MITRE is currently investigating the potential of a new generation of additive manufacturing (AM) to realize complex antenna geometries at low cost that are difficult to manufacture with conventional fabrication methods. This talk will discuss results of 3D printed dielectric and conductive material characterization, and give examples of several 3D printed antennas and RF devices that have been built and tested. A small, dual-polarized phased array was built to operate over 1 GHz – 7 GHz and scan +/- 45 degree over full azimuth. A proof of concept of multi-layer feed network, comprised of two- and three-way power splitters and embedded RF discrete components was also 3D printed as a single part to operate over 1 GHz – 6 GHz. It can be used as a beam-forming circuit for integration into 3D printed phased arrays. A novel bi-axial split resonator metamaterial was designed and built to demonstrate potential for a new class of frequency selective surface. Finally, best practices in design for AM of antennas based on experience with these prototypes will be presented.
