A novel conjugate matched feed for standard single reflector Compact Antenna Test Ranges (CATR) has recently been presented.

Significant reduction of the cross polarization component in the Quiet Zone (QZ) can be achieved with a dualpolarization feed in a nominal 1.5:1 bandwidth. In this paper, we report on the application of the proof-of-concept demonstrator for standard corner-fed CATR applications. The concept is validated by QZ probing. It is shown, that the spatial distribution of the cross polarization field of the QZ is significantly reduced and homogenized.
