Corrugated matched horn with low side-lobes for high performance offset reflector systems
A tri-pin tri-mode corrugated matched horn with low side lobes is proposed to compensate the cross-polar component in high performance offset reflector systems. The simulated results are presented, showing that the cross-polar isolation in the offset tri-reflector compact range is improved from 30.5dB to 48.2dB when the proposed horn is used.
