3d Printed antennas

This document describes the design of 3D printed antennas. It outlines initial inspirations from industry antennas and homemade designs. Early models included 3D printed mounts for dipole and tripole antennas. Further prototypes tested designs like a dipole and tripole antenna. The document then introduces the solution called the Copernican Gear Antenna, which uses 3D printed gears to enable three-dimensional turning of mounted antennas. This unique design offers potential for omnidirectional sensing and increased modularity for a wide range of applications.

3d Printed antennas By Allan Regis 1
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 Advantages Cost effective Wide variety available Compact Disadvantages Confined to two-dimensional board
Initial inspirations Homebrew Antennas 5 Antennas fashioned by individuals using whatever works Advantages Functional antennas that are cheap & easy to construct Disadvantages Typically fragile Aesthetic nightmare
Initial inspirations Metal 3D Printed Antennas 6 Prints Gallium to create a three- dimensional antenna array Advantages Highly innovative Customizable designs Disadvantages Very expensive Can 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 10 Dipole Antenna (Fourth wire is currently M.I.A.)
Works-like prototypes Tripole Antenna 11
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?

Key features 18 Glass domes protect insides from unwanted damage or tampering, but still allows operators to see inner mechanisms Antennas transmission lines go through hole in bottom glass, and through bottom of stand Copernicans 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
Equation-driven gears 21
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 antennas orientation via microprocessors in large machinery Increased WiFi reception for personal laptop computers
conclusions 23 Usefulness? The Copernican offers the potential for omnidirectional sensing with virtually any type of antenna Modularity? Copernican is cost efficient, and can be quickly customized to fit a wide 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!!
