Abstract
A printed Luneburg lens whose permittivity distribution is controlled by photo lithographically etching holes of different sizes into one side of a PCB ground plane is reported. The lens designed to operate in TE~01~ mode has a measured −3‐dB beamwidth of 5.2° with 14.2‐dB gain at 27.22 GHz for a 12.2λ, 13.4‐cm diameter lens. Its low profile, 3.175‐mm thickness, 85 g, ±20° scanning range, and 15% bandwidth makes it useful for land mobile telemetry and vehicular applications in the millimeter waveband. © 2007 Wiley Periodicals, Inc.
