Abstract

This paper describes the design of a compact polarizer that rotates the linear polarization of a fully metallic geodesic Luneburg lens antenna for applications requiring polarization diversity. The polarization rotation is achieved by loading the radiating aperture of the antenna with two metallic screens. The integrated antenna operates in the K a -band, from 25 to 31 GHz, showing around 20% bandwidth with S 11 below −10 dB, and a scanning range of 100°.
