Abstract

We present the material characteristics, device design, and device manufacturing process of high performance, low loss 3D printed GRIN lenses like a Luneburg-style lens. To validate the technology, a simple spherical, radially symmetric GRIN lens was designed and printed using a commercial DLP printer and low loss polymer dielectric material. The lens was mounted to a co-axe to waveguide transition and served to increase gain of the resulting antenna system. The device was tested in the Ka band, and the practical test results are compared against HFSS simulated results. The result is a passive lens design that has the capability form and steer beams in the Ka-band.
