Dual Polarized CATR Feed for Cross-Polarization Reduction

3300 MHz - 18000 MHz

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.
