A simple means using rectangular patch antennas to feed a 2D planar Luneburg lens is presented. The lens together with the patch launching system is modelled using commercial 3D electromagnetic software. The −23 dB return loss, better than −20 dB port to port isolation of the patches, as well as 15 dB antenna gain and 5.3° −3 dB H‐plane (lens plane) beamwidth indicate excellent lens performance potential at 23.3 GHz. © 2007 Wiley Periodicals, Inc.
