Project goal
Design antennas with unique aesthetic designs, and dual polarization for good performance.
2
Initial inspirations Antenna Designs in Industry
3
Patch Antennas Dish Antenna
Horn Antenna
Turnstile Antenna
Initial inspirations Theoretical/Research Antennas
4
Metal etched onto circuit boards
AdvantagesCost effectiveWide variety availableCompact
DisadvantagesConfined to two-dimensional
board
Initial inspirations ‘Homebrew’ Antennas
5
Antennas fashioned by individuals using ‘whatever works’
AdvantagesFunctional antennas that are
cheap & easy to construct
DisadvantagesTypically fragileAesthetic nightmare
Initial inspirations Metal 3D Printed Antennas
6
Prints Gallium to create a three-dimensional antenna array
AdvantagesHighly innovativeCustomizable designs
DisadvantagesVery expensiveCan be fragile
Early antenna models
7
Two 3D printed mounts, plus base plate
Two screws hold antenna together
Copper wires fed through small loops at the of the 3D
printed ‘arms’
Form & Function Studies: Dipole Antenna
Early antenna models Same two screws can support
tripole design
Each dipole carefully measured to be equidistant from center
Uses two of the same pieces for increased modularity
Form & Function Studies: Tripole Antenna
8
Early antenna models
9
Mounting Pieces support 3D printed antennas for either tripole or dual dipole antennas
Form & Function Studies: Tripole Antenna
Works-like prototypes Tripole Antenna w/ Support
12
Tripole pieces 3D printed in acrylic to
preserve finer details
Design challenges
13
How might we incorporate more unique aesthetic designs?
Can we make the antennas modular, so customers could get more use from them?
What unique functions can our technology provide that competitors cannot?
The solution:
The Copernican Gear Antenna

Key features
18
Glass domes protect insides from unwanted damage or tampering, but still allows operators to see
inner mechanismsAntenna’s transmission lines go through hole in
bottom glass, and through bottom of
stand
Copernican’s gears enable three-dimensional turning of
mounted antennas, which can give non-tripole antennas more
sensory capabilities
Key features
19
Tripole OR dual dipole can snap into center gear. Highly modular
Radial marks help determine exactly how far from rest position the antenna has
turned
Key features
20
Bottom stand is removable, meaning the Copernican can be
integrated into a variety of systems (other than tabletop
sensing)
All gears are equation-driven, and can be modified to a
certain size within seconds, while maintaining optimal
meshing conditions
Markets and uses
22
Could be used as a tabletop research antenna for test field strengths in Communication Labs
Gears can be attached to electromechanical systems to control the antenna’s orientation via microprocessors in large machinery
Increased WiFi reception for personal laptop computers
conclusions
23
Usefulness? The Copernican offers the potential for omnidirectional sensing withvirtually any type of antenna
Modularity? Copernican is cost efficient, and can be quickly customized to fit awide variety of sensing applications
Elegance? The Gear Antenna breaks the monotony of standard antenna designs,especially those of dipoles, dual dipoles, and tripole antennas.
No other product on the market can provide all these benefits…
The Gear Antenna is a GO!!
