Customized shaped Luneburg Lens Antenna Design by Additive Fabrication

—In this paper we present the design and fabrication of modified Luneburg lens antennas. The lens was designed using a quasi-conformal transformation optics approach and fabricated using additive manufacturing. We experimentally validated our methods by designing and fabricating a modified Luneburg lens operating at 24–40 GHz with a beamforming capability of -50° to 50°.
