Multi-band antenna system for satellite communications

摘要

The present invention provides an improved antenna system on moving platform that is in communication with multiple satellites for simultaneous reception and transmission of RF energy at multiple frequencies. The antenna is implemented as a multi-beam, multi-band antenna having a main reflector with multiple feed horns and a sub-reflector having a reflective surface defining an image focus for a Ka band frequency signal and a prime focus for a Ku band frequency signal.
