Ansoft Designer™Planar EM Capability Overview• Designer can accurately simulate very large structures, quickly!

– SVD fastsolve– Low memory requirements

• Geometries can be drawn or imported– User friendly GUI– Dxf, iges, and popular geometry imports– Ansoft Links for other CAD tools

• Full Parameterization• Solver on Demand

– The ability of designer that lets the user decide which solver to use on an element by element basis

• Co-Simulation– The capability of designer to seamlessly integrate circuit, system

and EM simulations

• Matrix Plot– 2D/3D Cartesian, polar plotting, gain, etc

• Fields– 3D Field Plots, Data Edit Sources, Radiation Patterns, etc

Ansoft DesignerAnsoft Designer™™ Planar EMPlanar EMPatch Patch EstimatorDesigner allows easy design of single patches.Patch estimator tool gives a good first approximation.

T-Line Estimates transmission-line quantities such as the characteristic impedance of a line, the line width corresponding to a characteristic impedance, the guided wavelength and the effective relative permittivityof a microstrip line or stripline, and the losses associated with a line.

Impedance Match Estimates the dimensions of a quarter-wave section to match a load impedance to an input impedance. Also estimates the location and dimension of a tuning stub for matching an input impedance to a complex load impedance.

Printed Antennas Estimates the dimensions of patch antennas.

Microwave Calculator Converts between the mismatch loss, the reflection coefficient, the return loss, and the voltage standing wave ratio (VSWR). Also converts between dB and the ratio for both power and voltage values.

Units Sets the current working units.

The menus in the Estimate module have the following functions:

To access the Estimate module, click Estimate on the Planar EM menu. Use the Estimate module to estimate parameters related to the following:

• Microstrip line

• Quarter-wave transformer

• Tuning stub

• Rectangular patch

• Circularly polarized (CP) patch
