Design and Verification of Cross-Polarization Compensation Feed for Single Reflector Compact Antenna Test Range over a Wide Bandwidth



Measurement applications using a Compact Antenna Test Range (CATR) often require low cross-polarization or high polarization purity of the Quiet Zone (QZ).

This requirement is often the main motivation for choosing the more complex and thus expensive compensated dual reflector system as opposed to the simpler and cheaper single reflector system. In this paper, a novel wide-band, conjugate matched feeding concept is presented.
