ABSTRACT

This paper exhibits the design and implementation of a compact dual-band band-pass filter onboth inorganic (Rogers RT Duroid 5880) and organic (Teslin SP1200) substrates. The proposedfilter which works on the principle of signal interference technique has a parallel combinationof short-circuited coupled line and an H-shaped network of transmission lines with open stubs.Due to the superposition of signals of the two transmission paths, a second order dual-bandband-pass response with four transmission zeroes is achieved. To validate the proposed de-sign, theoretical analysis using lossless transmission line model is carried out and acknowl-edged. The developed dual-band filter prototype implemented on Rogers RT Duroid 5880with center frequencies 1.3 GHz and 4.224 GHz has 3-dB fractional bandwidths of 82.23%(0.79-1.859 GHz) and 19.64% (3.73-4.56 GHz), respectively. Filter prototype implemented onTeslin SP1200 with center frequencies 1.17 GHz and 4.06 GHz has 3-dB fractional bandwidthsof 82.56% (0.69-1.656 GHz) and 20.59% (3.645-4.481 GHz), respectively. The simulated andexperimental results are in good congruence with each other. The proposed dual-band band-pass filter can be used in various wireless applications, for example GSM900 (880-915 MHz),aircraft surveillance (960-1215 MHz), IRNSS (1.164-1.188 GHz), amateur radio (1.24-1.30GHz), GPS (1.559-1.61 GHz), satellite phones (1.616-1.626 GHz), and satellite communica-tion (3.7-4.2 GHz).

CHAPTER 1

INTRODUCTION

Band-pass filters (BPFs) are significant and integral components of the wireless framework intrend to forestall signal interference, unwanted signal dismissal and to sustain low insertionloss in the pass-band. A need for dual/multi-channel communication setup with high bitrateshas emerged following the advancement in technology. Features like compactness, multibandoperation and wider pass bands and stopbands incorporated in BPFs have proved to be ad-vantageous to the system. Multiple techniques [1]-[14] have been affirmed to construct dualband band-pass filters (DBBPFs). Resonators like complementary split-ring resonator (CSSR)[1], meander split loop resonator [2], penta-mode resonator (PMR) [3], T-shaped resonator [4],stepped impedance resonators (SIRs) [5],[6],[15],[16],[17],[19], stub loaded resonators [7]-[8]and open-loop ring resonators (OLRRs) [20] are highly prevalent in the design of dual bandBPFs. In [1], an SL-OCSRR is designed which consists of two dual band BPFs having zerothat can be adjusted. A meander split loop resonator has been used in [2] to construct a dualband BPF having a wide bandwidth and favorably low insertion loss. [3] utilizes a PMR (PentaMode Resonator) to generate the bands. The first pass-band is achieved by the two initialmodes, and the second pass-band is achieved by the three latter modes. In [4], a tunable mi-crostrip dual band BPF is developed making use of a resonator which resembles a T in shapealong with feeding lines. The characteristics of the filter can be varied by adjusting the physicallengths. Tri section SIR is incorporated in [5] to construct a BPF which plays a vital role inwireless applications including WLAN. [6] uses a cross stub SIR to fabricate a DW-BPF whichproves to be advantageous compared to half wavelength conventional resonators. In [7], thedesign of a dual band BPF having a wider stop-band and high isolation has been validated byemploying open circuited stub loaded resonators. [16] employs a modified SIR having a sin-uous arrangement to develop a dual band BPF in absence of an external impedance matchingunit. In [17], BPF with a DSIR (Defected SIR) is proposed where DSIR have a comparativelylower resonant frequency which in turn results in a relatively smaller size of the circuit. TheBPF used in [19] portrays a novel feature of obtaining two tunable pass-bands at the requiredfrequencies, achieved by using SIRs in comb-like configuration. [20] utilizes OLRRs (openloop ring resonators) to obtain a dual band BPF with low loss. In [9], a modified defected mi-crostrip structure using an F-shaped spurline is proposed to realize a DBBPF with independentcontrol of central frequencies. A compact and high selectivity DBBPF employing a dual-modedefected ground structure resonator and a dual-mode open-stub loaded stepped impedance res-onator (DOLSIR) is proposed in [10]. The advantage of the filter is that by changing theparameters of DOLSIR, the second passband frequency can be shifted in a wide range withoutsignificantly affecting the first pass band and out of band performances. A coplanar waveguide

(CPW) feeding based DBBPF using series stepped capacitance and shunt meandered line in-ductance is reported in [11]. Novel resonator like quad-mode resonator is used in [27]-[28] todevelop dual-band filters where bandwidths can be adjusted simultaneously by stubs. A com-pact, dual band BPF is attained in [29] utilizing stub-loaded spiral short circuit λ/4 SIR havingwide stop-band characteristics. MMRs are put in use in [31] to construct UWB BPF with animprovement in upper stop-band performance. Apart from these techniques, signal interferenceconcept is also widely used in the design and development of DBBPFs [12]-[14],[21]-[26]. Hy-brid ring and branch line hybrid based transversal filtering sections loaded with double stubsare proposed in [12] to realize DBBPFs with widely separated passbands. A high selectivityDBBPF with 3-dB fractional bandwidths (FBWs) of 28.8% and 22.7% is developed using aT-shaped structure [13]. A compact dual-wideband BPF comprising quarter wavelength trans-mission lines and a short-circuited coupled line is reported in [14]. The fabricated prototypeoccupies an area of 0.16λg × 0.15λg, where λg is the guided wavelength of 5030 transmissionline at the center frequency of the first passband. In [21], a compact UWB BPF is demonstratedwhich makes use of the signal interference technique consisting of short-circuited coupled linesand a transmission line connected parallelly. [22] reports a simple dual-passband planar filtermodel with two transmission lines connected in parallel synthesizing multiple transmission ze-roes. Open stubs incorporated with a generalized branch-line hybrid have been employed forthe construction of a dual band planar BPF in [23]. Two in-parallel stepped impedance trans-mission lines have been utilized to design a double pass-band filter in [24], where the bandsare asymmetric with respect to bandwidth. [25] exhibits wide band planar filters with sharprejection and low insertion loss employing signal interference concepts.

Due to the exponential growth in the usage of communication devices, the e-waste is in-creasing tremendously. The substrate materials involved in the manufacturing of these mi-crowave devices or filters are inorganic and have an adverse effect on the environment. Inrecent years, the use of various biodegradable materials as substrates has been successfullydemonstrated. Paper being widely available renewable material, lightweight, and cheap is agood alternative for inorganic substrates. Flexible radio-frequency identification device (RFID)tag exploiting paper substrate and inkjet printing technology is presented in [33]. In [34], anultra-wideband antenna is realized through ink-jetting of conductive inks on commercial papersheets. A flexible monopole antenna using Teslin paper substrate is reported in [35]. A compactand wide harmonic suppressed rat-race coupler employing modified stepped impedance stuband interdigitated slot resonator is fabricated on the paper substrate [36]. As the paper materialhas low-temperature tolerances, the traditional soldering method for mounting components onit is a difficult task. In [37], this issue is addressed using an industrial solder process with alow-temperature solder. The paper substrate also lacks good barrier properties with water. Inorder to protect the hydrophilic substrates from moisture, parylene layer is deposited on a papersubstrate based dual-band antenna and submerged in distilled water for 48 days, and there is nosignificant degradation observed in its performance [38]. [39] demonstrates an innovative tech-nique of composing SIW components and antenna with paper substrate where the fabrication is

carried out with bottom and top aluminium foils and milling manufacturing respectively. Thisproject presents the design of a compact DBBPF based on signal interference technique and itsimplementation on Rogers substrate, as well as paper substrate. The proposed design consistsof a short-circuited coupled line in path 1 and an H-shaped network of transmission lines withopen stubs in path 2. Due to the interference of signals from these two paths, a second-orderdual-band bandpass response with good inter stopband is observed. The closed-form equationsfor the transmission zeros (TZs) are derived based on the rigorous scattering-parameters theory.A DBBPF prototype with center frequencies 1.17 GHz and 4.06 GHz is fabricated on RogersRT Duroid 5880 (dielectric constant = 2.2, loss tangent = 0.0009) substrate and Teslin SP1200paper substrate (dielectric constant = 2.23 and loss tangent = 0.014). The fabricated prototypeoccupies an area of 0.125λg × 0.155λg for Rogers RT Duroid 5880 and 0.117λg × 0.136λg forTeslin SP1200. The full-wave simulated and experimental results are almost in good agreementwith each other.Following are some block diagrams showing the application of BPFs in various fields:

2.3 Compact Wideband Bandstop Filter With Five Trans-mission Zeros[44]

AUTHOR:Mrinal Kanti Mandal, Member, IEEE, Kandimalla Divyabramham, and Vamsi Kr-ishna Velidi[44]Publication:IEEE Microwave and Wireless Components Letters 22, no. 1 (2011): 4-6.[44]Year-2011INFERENCE:By combining the signal interference technique and the input-output coupling ,a compact fil-ter configuration is presented that provides five transmission zeros. The grooves on the innersides of the lines result in a stepped impedance line that reduces the number of zeros to four.This problem can be avoided by increasing the number of the grooves while keeping their di-mensions small to obtain θe=θo. Although five zeros are not clear from the measurement, theexpected attenuation level is achieved using a single unit and without any open-stub. Due to thecoupled-line geometry, the width of the filter is so thin that most of the time it is thinner thanthe hosting 50 Ω line. The BSF can be used as a building block of a high performance compactlow-pass filter. [44]

In this paper, two compact dual-band BPFs with closely spaced passbands and multiple trans-mission zeros are presented. The Kf can be easily adjusted by changing the parameter of S2.The proposed dual-band BPFs have very low Kf , wide stopband suppression, high passband se-lectivity, etc. These merits make the proposed filters attractive for channel selection in wirelesscommunication systems.

CHAPTER 3

DESIGN PROCEDURE

3.1 Design and analysis of the filter

3.1.1 Objectives of the filter1. To design a dual-band band-pass filter that has a good isolation between two passbands

(Radio Navigation and fixed satellite applications).

2. To obtain bandwidth of more than 500 MHz in each passband.

3. To obtain passband return loss greater than 20 dB.

4. To obtain insertion loss less than 0.5 dB.

5. To obtain high selectivity of the filter.

6. To obtain a filter which is compact size.

3.1.2 Transmission model of the filter

Figure 3.1: Transmission line model of the proposed dual-bandBPF having impedance values (a) Z1 = 50Ω (b) Z2 =120Ω (c) ZS = 90Ω (d) ZE = 100Ω (e) ZO = 85Ω

The transmission line model of the proposed DBBPF as shown in Fig. 3.1 consists oftwo transmission paths. Path 1 consists of a short-circuited coupled line having characteristicimpedances ZE and ZO, while path 2 consists of an H-shaped network of transmission lines(Z1,Θ), (Z2,Θ) and open stubs (ZS, Θ). The electrical length of transmission lines and stubsconsidering quarter wavelength is Θ= π/2 at the design frequency (f0).This arrangement provides a certain set of specifications for the proposed filter. Four transmis-sion zeros with two pass bands which are divided by the central frequency can be observed.Due to symmetry of the circuit the scattering-parameters can be derived by lossless transmis-sion theory equations. The reflection coefficient is S11 and transmission coefficient is S21.The impedance values of ZE, ZO, Z1, Z2, ZS are stated in Fig. 3.1. The same have beenderived after simultaneous analysis and simulations in Ansoft Designer SV (Circuit simulator).

3.1.3 Analysis of S Parameters

The theory of the design is validated after obtaining S-parameters by performing ABCD andY-parameter conversion. The relationship between S-parameters and Y-parameters is found tobe

S11 =Y 20 − Y 2

11 + Y 221

(Y11 + Y0)2 − Y 221

(1)

S21 =−2Y21Y0

(Y11 + Y0)2 − Y 221

(2)

12

The transmission zeros can be obtained when S21=0 is satisfied which leads to Y21=0. TheABCD parameters of the short circuited coupled line which is in path 1 can be obtained from[21] and for the H-shaped transmission line network can be written as

The transmission Zeroes can be obtained when S21=0 is satisfiedWe know that,

Since, −2YO/∆Y is a constant,Therefore, we will analyse Y21=0The equations 7 and 9 are derived respectively from [42] (page number 102, table number 4.2)As the Paths 1 and 2 are parallel to each other considering admittance (Y-parameter) calculationinstead of impedance calculation will be prudent. Since the transmission zero frequencies canbe calculated by setting Y21 = 0, the Y21 of the filter can be written as

[Y21]Filter = [Y21]Path1 + [Y21]Path2 =−1

On solving (21) by using Z1 = 50, Z2 = 120, Zs = 90, ZE = 100, ZO = 85;We get,

θfTZ2= 80.6555

θ0 = 90

fTZ2 =80.655

90(2.65) = 2.37GHz

Now,θTZ3 = π − θTZ2 = 99.345

fTZ3 =99.345

90(2.65) = 2.925GHz

Considering f0 = 2.65 GHz and Θ0 =π/2, and employing equations (14) and (15), TZs areattained at 2.37 GHz and 2.92 GHz for impedance values of Z1 = 50 Ω, Z2 = 120 Ω, ZS = 90Ω, ZE = 100 Ω and ZO = 85 Ω. The calculated TZ frequencies are exactly matching with thecircuit simulated values and therefore, validate the closed form design equations.

Figure 3.2: Circuit simulated magnitude response of the proposeddual-band BPF

The magnitude response in Fig. 3.2 has been obtained from simulations carried out in cir-cuit simulator (Ansoft Designer SV).Ansoft Designer is a circuit simulating tool which is used for designing and simulating RF,complex analog and mixed applications which then further, analyses signal integrity and veri-fies high performance package/IC designs.

The analysis performed met the prime objectives of our proposed filter design.

1. Bandwidth obtained – more than 500MHz

2. Return loss – more than 20dB

3. Insertion loss – less than 0.5dB

4. Highly selective

The two passbands obtained targets specific applications –

1. Radio navigation

2. Fixed navigation

The values of impedances are varied and the S-parameters and 3dB-FBW are examined andrespective alteration in the simulation is noted.

• A study on Z1 increase delineates reduction in return loss in the passbands. Addition-ally, there is a noticeable shift in the central frequencies of both the pass-bands. There isalso a narrow decrease in the width of the stopband.

• A surge in Z2 value increases the return loss in both the passbands by an apprecia-ble amount. No other significant change is observed.

• An increase in the ZS value increases the return loss in the passbands by a favorableamount. There is a slight shift in the central frequencies in both the passbands.

• A hike in k value increases the return loss in both the passbands.

• On increasing the value of Z1, the 3dB-FBW increases for both the pass-bands.• A surge in Z2 value shows a decrease in the 3dB-FBW for both the pass-bands.

17

• Though change in ZS led to no significant deviation in 3dB-FBW, however, as ZS increasesthe center frequency ratio decreases.

• As k increases, the 3dB-FBW decreases for both the pass-bands.

The variations can be observed clearly in Fig.3.3, 3.4, 3.5, 3.6. The above results havebeen plotted by using MATLAB and varying the values. Minor changes are observed in thecharacteristics by varying the values of k, Z1, Z2, ZS.

3.1.4 Design and Analysis in HFSS

Further, the filter has been designed and analyzed in HFSS (an EM full wave simulator) wherethe specifications of the substrate have been obtained. The implementation has been done intwo substrates: -

1. Rogers RT Duroid 5880 (Inorganic Substrate)

2. Teslin SP1200 Paper Substrate (Organic Substrate)

3. HFSS abbreviates for High Frequency Structure Simulator.

4. HFSS is a system which employs Tetrahedron Mash element. An arbitrary 3D geometri-cal model can be solved, even figures including complexity.

5. It may be utilized to analyze certain parameters. E.g. S parameters, EM fields, VSWRetc.

Figure 4.3: Simulated and measured S-parameters of the Rogers substratebased DBBPF.

A comparison of simulated and measured frequency responses is depicted in the Fig 4.3.The center frequencies of the two passbands are obtained at 1.3 GHz and 4.224 GHz for 3dBbandwidths ranging from 0.79 to 1.859 GHz and 3.73 to 4.56 GHz, respectively. In contrast tothe calculated transmission zeroes, obtained at frequencies 0, 2.37, 2.92 and 5.3 GHz, the mea-sured transmission zeroes for the tested prototype were obtained at 0, 2.34, 2.85 and 5.1GHz.The insertion loss was measured as 0.35 dB an 0.55 dB, while the return loss was found to be23.12 dB and 20.68 dB, for the first and second passbands respectively. For both the passbands,the group delay is less than 1ns.The deflection of the measured result from the simulated one can be attributed to connector

The measurements above were carried out by using Vector Network Analyzer.

A VNA (Vector Network Analyzer) is an electronic device which contains a source, whichgenerates a preset stimulus signal as well as a bunch of receivers, which determines the varia-tions in the signal caused due to the presence of the DUT (Device Under Test).

Figure 4.4: Working of a VNA

First, the signal stimulus is fed into the DUT. The VNA, then measures the reflected signalfrom the input end and the signal that passes to the output end. The VNA receivers collectand measure the output signals and compare them with the preset stimulus signal. Further, themeasured signals are processed by an external or internal PC. These are later delivered to thedisplay unit.

VNAs are used to measure a variety of signal characteristics:

1. S-parameters (S11, S21 etc.)

2. Gain

3. Insertion loss

4. Electrical length

5. Delay

CHAPTER 5

5.1 Implementation using inorganic substrate

Taking a note of the above performed analysis, the design was implemented on Teslin SP1200.To provide conduction the organic substrate was layered with an adhesive copper layer of thick-ness 0.035mm on both its upper and bottom surfaces. The fabrication process began withsketching and etching out the DBBPF layout of the the adhesive copper which was then gluedon the Teslin paper substrate. Two substrate of thickness 0.305mm each were combined withan adhesive to obtain the desired substrate height of 0.61mm.A prototype of the filter having dimensions L1 = 10mm, L2 = 21.4mm, L3 = 24.45mm, Lc =21mm, Ls = 21.7mm, W1 = 2.4mm, W2 = 2.5mm, W3 = 0.35mm, Wc = 0.75mm, Ws = 1mm,d = 0.4mm, g = 1.852mm is shown in the fig 13. Its area coverage is 0.127λg0.148λg.

Figure 5.2: Fabricated prototype ofthe proposed DBBPF us-ing Teslin SP1200-bottomview.

A comparison of simulated and measured frequency responses is depicted in the Fig.15.The center frequencies of the two passbands are obtained at 1.17GHz and 4.06 GHz for 3dBbandwidths ranging from 0.69 to 1.656 GHz and 3.645 to 4.481 GHz, respectively. In con-trast to the calculated transmission zeroes, obtained at frequencies 0, 2.37, 2.92 and 5.3 GHz,the measured transmission zeroes for the tested prototype were obtained at 0, 2.34, 2.85 and5.1GHz. The insertion loss was measured as 0.48dB an 0.87dB, while the return loss was foundto be 25.64dB and 19.85dB, for the first and second passbands respectively.

Fig.16. shows the simulated and experimental group delay of the proposed DBBPF. For boththe passbands, the group delay is less than 1ns. The deflection of the measured result from thesimulated one can be attributed to connector losses and fabrication restraints.

CONCLUSION

The above demonstration of a dual-band BPF on organic and inorganic substrate is a successfulin meeting the expectations. The design exhibits a filter framework having a short circuited cou-pled line and an H-shaped network of transmission lines. The application of lossless transmis-sion line theory verified the frequencies of transmission zeroes obtained for both the substrates.Passbands of the proposed filter are significantly separated by a stopband which makes it suit-able for using in different communication, navigation, etc. systems. With effective circuit sizeof 0.125λg0.155λg(inorganic substrate) and 0.117λg0.136λg (organic) the compactness of thefilter can be verified. For Teslin SP1200 paper substrate the measured 3-dB FBWs are 82.56%and 20.59% around the center frequencies of 1.17 GHz and 4.06 GHz, respectively. Finally, thework also addresses the environmental concern and provided a solution to the growing e-waste.

This paper exhibits the design and implementation of a compact dual-band bandpass filter on paper sub-strate. The proposed filter which works on the principle of signal interference technique has a parallelcombination of short-circuited coupled line and an H-shaped network of transmission lines with openstubs. Due to the superposition of signals of the two transmission paths, a second order dual-band band-pass response with four transmission zeroes is achieved. To validate the proposed design, theoreticalanalysis using the lossless transmission line model is carried out and acknowledged. The developeddual-band filter prototype with center frequencies 1.17 GHz and 4.06 GHz has 3-dB fractional band-widths of 82.56% (0.69–1.656 GHz) and 20.59% (3.645–4.481 GHz), respectively. The simulated andexperimental results are in good congruence with each other. The proposed dual-band bandpass filtercan be used in various wireless applications, for example, Global System for Mobile Communications(880–915 MHz), Aircraft surveillance (960–1215 MHz), Indian Regional Navigation Satellite System(1.164–1.188 GHz), Amateur radio (1.24–1.30 GHz), Global Positioning System (1.559–1.61 GHz),Satellite phones (1.616–1.626 GHz), and Satellite communication (3.7–4.2 GHz).

1. Introduction

Band-pass filters (BPFs) are significant and integral componentsof the wireless framework in trend to forestall signal interference,unwanted signal dismissal and to sustain low insertion loss in thepass-band. A need for dual/multi-channel communication setupwith high bitrates has emerged following the advancement in tech-nology. Features like compactness, multiband operation and widerpassbands and stopbands incorporated in BPFs have proved to beadvantageous to the system. Multiple techniques [1–18] have beenaffirmed to construct dual-band band-pass filters (DBBPFs).Resonators like complementary split-ring resonator (CSSR) [1],meander split loop resonator [2], penta-mode resonator (PMR)[3], T-shaped resonator [4], composite right-/left-handed resonator[5], stepped impedance resonators (SIRs) [6,7] and stub loadedresonators [8,9] are highly prevalent in the design of dual bandBPFs. In [10], a modified defected microstrip structure using anF-shaped spurline is proposed to realize a DBBPF with independentcontrol of central frequencies. A compact and high selectivity

DBBPF employing a dual-mode defected ground structure res-onator and a dual-mode open-stub loaded stepped impedance res-onator (DOLSIR) is proposed in [11]. The advantage of the filter isthat by changing the parameters of DOLSIR, the second passbandfrequency can be shifted in a wide range without significantlyaffecting the first passband and out-of band performances. A copla-nar waveguide (CPW) feeding based DBBPF using series steppedcapacitance and shunt meandered line inductance is reported in[12]. In [13–15], different coupled line configurations and stubsare used to realize DBBPFs with multiple transmission zeros andpoles. Apart from these techniques, signal interference concept isalso widely used in the design and development of DBBPFs [16–18]. Hybrid ring and branch line hybrid based transversal filteringsections loaded with double stubs are proposed in [16] to realizeDBBPFs with widely separated passbands. A high selectivity DBBPFwith 3-dB fractional bandwidths (FBWs) of 28.8% and 22.7% isdeveloped using a T-shaped structure [17]. A compact dual-wideband BPF comprising quarter wavelength transmission linesand a short circuited coupled line is reported in [18]. The fabricatedprototype occupies an area of 0.16kg 0.15kg , where kg is theguided wavelength of 50 X transmission line at the center fre-quency of the first passband.

dual-band BPFs with symmetrical quasi-reflectionless differential-mode behavior are proposed in [19].

Due to the exponential growth in the usage of communicationdevices, the e-waste is increasing tremendously. The substratematerials involved in the manufacturing of these microwavedevices or filters are inorganic and have an adverse effect on theenvironment. In recent years, the use of various biodegradablematerials as substrates has been successfully demonstrated. Paperbeing widely available renewable material, lightweight, and cheapis a good alternative for inorganic substrates. Flexible radio-frequency identification device (RFID) tag exploiting paper sub-strate and inkjet printing technology is presented in [20]. In [21],an ultra-wideband antenna is realized through ink-jetting of con-ductive inks on commercial paper sheets. A flexible monopoleantenna using Teslin paper substrate is reported in [22]. A compactand wide harmonic suppressed rat-race coupler employing modi-fied stepped impedance stub and interdigitated slot resonator isfabricated on the paper substrate [23]. As the paper material haslow-temperature tolerances, the traditional soldering method formounting components on it is a difficult task. In [24], this issueis addressed using an industrial solder process with a low-temperature solder. The paper substrate also lacks good barrierproperties with water. In order to protect the hydrophilic sub-strates from moisture, parylene layer is deposited on a paper sub-strate based dual-band antenna and submerged in distilled waterfor 48 days, and there is no significant degradation observed inits performance [25].

This paper presents the design of a compact DBBPF based onsignal interference technique and its implementation on papersubstrate. The proposed design consists of a short-circuited cou-pled line in path 1and an H-shaped network of transmission lineswith open stubs in path 2. Due to the interference of signals fromthese two paths, a second-order dual-band bandpass responsewith good inter stopband is observed. The closed-form equationsfor the transmission zeros (TZs) are derived based on the rigorousscattering-parameters theory. A DBBPF prototype with center fre-quencies 1.17 GHz and 4.06 GHz is fabricated on the TeslinSP1200 paper substrate having dielectric constant 2.23 and losstangent 0.014. The fabricated prototype occupies an area of0.117kg 0.136kg . The full-wave simulated and experimentalresults are almost matching with each other.

2. Design and analysis of the proposed DBBPF

The transmission line model of the proposed DBBPF as shown inFig. 1 consists of two transmission paths. Path 1 consists of a shortcircuited coupled line having characteristic impedances ZE and ZO,while path 2 consists of an H-shaped network of transmission lines(Z1; h), (Z2; h) and open stubs (ZS; h). The electrical length of trans-mission lines and stubs considering quarter wavelength ish ¼ p/2 at the design frequency (f 0). The circuit simulated fre-quency responses of the proposed DBBPF are depicted in Fig. 2.Two passbands separated by a stopband and four TZs can beobserved.

The response of the proposed design is validated after obtainingS-parameters by performing ABCD and Y-parameter conversion.The relationship between S-parameters and Y-parameters is foundto be

ð1Þ

S21 ¼ 2Y21Y0

ðY0 þ Y11Þ2 Y221

ð2Þ

The TZs can be obtained when S21 = 0 is satisfied which leads toY21 = 0. The ABCD parameters of the short circuited coupled linewhich is in path 1 can be obtained from [26] and for theH-shaped transmission line network can be written as

As the paths 1 and 2 are parallel to each other considering admit-tance (Y-parameter) calculation instead of impedance calculationwill be prudent. Since the TZ frequencies can be calculated by set-ting Y21 = 0, the Y21 of the filter can be written as

Considering f 0 = 2.65 GHz and h0 ¼ p/2, and employing Eqs.(17) and (18), TZs are attained at 2.37 GHz and 2.92 GHz for impe-dance values of Z1 = 50 X, Z2 = 120 X, ZS = 90 X, ZE = 100 X andZO = 85 X. The calculated TZ frequencies are exactly matching withthe circuit simulated values and therefore, validate the closed formdesign equations. The design analysis will be engaged for imple-mentation of proposed design on paper substrate. The values ofimpedances are varied and the S-parameters and 3 dB-FBW areexamined and respective alteration in the simulation is noted.Fig. 3 captures the deviations and provides an insight into thebehaviors of the above mentioned parameters. Although a studyon Z1 increase delineates reduction in return loss in the passbands,we notice that a surge in Z2; ZS and coupling factor (K = (ZE-ZO)/(ZE+ZO)) values increases the return loss in both the passbandsby an appreciable amount. The 3-dB FBW variations with respectto various parameters are shown in Fig. 4. On increasing the value

of Z1, the 3 dB-FBW increases for both the pass-bands while anopposite trend is observed when Z2 and K are increased. Thoughchange in ZS led to no significant deviation in 3 dB-FBW, however,as ZS increases the center frequency ratio decreases.

3. Fabrication and measurement

On the basis of above mentioned analysis, the final impedancevalues are chosen as Z1 = 50 X, Z2 = 120 X, ZS = 90 X, ZE = 100 Xand ZO = 85 X. The electrical length of all the transmission linesis p/2 at the design frequency of f 0 = 2.65 GHz. The proposedDBBPF is designed on a Teslin SP1200 paper substrate and an adhe-sive copper sheet of thickness 0.035 mm has been used as the con-ductive layer on the top and bottom of the substrate. Thefabrication process of the proposed DBBPF is described as follows:at first, the DBBPF layout is sketched and etched out from the adhe-sive copper and then it is pasted on the Teslin paper substrate. Thedesigned Teslin paper DBBPF has a substrate height of 0.61 mm.The available paper substrate height is 0.305 mm, so two papershave been integrated with an adhesive to get the required height.The layout of the proposed filter is depicted in Fig. 5. The dimen-sions are L1 = 10 mm, L2 = 21.4 mm, L3 = 25.35 mm, LC = 21 mm,LS = 19.7 mm, W1 = 1.82 mm, W2 = 1.9 mm, W3 = 0.27 mm,WC = 0.59 mm, WS = 0.64 mm, d = 0.4 mm, and g = 1.1 mm. Thefabricated prototype shown in Fig. 6 occupies an area of0.117kg 0.136kg and it is tested using Keysight TechnologiesN9926A Vector Network Analyzer.

Fig. 7(a) depicts the comparison of simulated and measuredfrequency responses for proposed DBBPF. The measured 3 dBbandwidths for both the passbands are from 0.69 to 1.656 GHzand 3.645 to 4.481 GHz, respectively, and their center frequenciesare 1.17 GHz and 4.06 GHz, respectively. The measured insertionloss (return loss) at first and second center frequencies are0.48 dB (25.64 dB) and 0.87 dB (19.85 dB), respectively. The testedprototype obtained TZs at 0, 2.34, 2.85 and 5.1 GHz, respectively(where as the calculated TZ frequencies are 0, 2.37, 2.92 and

The slightdeflection between the simulated and measured results may beimputed to fabrication tolerances and connector losses. Table 1highlights the advantages of the proposed DBBPF when comparedto the previously reported filters. The proposed DBBPF is compactand has good 3-dB FBW. Except for this DBBPF, all other designs aremanufactured using non-organic substrates.

4. Conclusion

The filter structureemploys a short circuited coupled line and an H-shaped networkof transmission lines and open circuit stubs. The frequencyresponse of the filter contains two passbands separated by a goodstopband. The transmission zero frequencies have been success-fully verified by employing a lossless transmission line theory.The fabricated prototype occupies an area of 0.117kg 0.136kg .The measured 3-dB FBWs are 82.56% and 20.59% around the centerfrequencies of 1.17 GHz and 4.06 GHz, respectively. The developedDBBPF can be used in telecommunication, navigation and satellitecommunication applications.
