ABSTRACT:
Compact multi-band antenna system (500) includes a main reflector (502) having a shaped surface of revolution about a boresight axis of the antenna operable at a plurality of frequency bands spectrally offset from each other. A multi band feed system (300) is provided for the main reflector that includes a subreflector (304) formed as a shaped surface of revolution about the boresight axis of the antenna, and a horn antenna (302). The horn antenna has one or more ridges (312) disposed in a throat region (314) of the horn antenna extending in a direction aligned with the boresight axis (3100of the antenna. The horn antenna is coupled to the shaped surface of revolution defining the subreflector.
