Wide bandwidth multiband feed system with polarization diversity

摘要: A multiband feed system for a reflector antenna, capable of operating simultaneously at plurality separate bands wide bandwidths and having both frequency polarization diversity, comprises common tapered waveguide carrying the multiplexed orthomode junctions spaced along length coupling signals in single band out waveguide. 90° 180° narrowband devices between transducers provide diversity. dual-depth corrugated flared horn beamwidth saturation mode with gives radiation pattern low cross-polarization content nearly equalized subreflector illumination all operation.
