Dual Polarized CATR Feed for Cross Polarization Reduction

CXR
A novel CATR feed concept to significantly improve the cross-polar performance of any uncompensated CATR systems, such as side/corner-fed single reflector systems. Provides wideband dual-polarized conjugate field matching, effectively cancelling the Geometrical Optics (GO) cross-polar component induced by the offset reflector of any single reflector CATR configuration.
