Abstract
An efficient multi-beam antenna system for use with a high capacity communications satellite or spacecraft that maximizes frequency re-use of the allocated frequency spectrum. The antenna system has first and second offset reflectors disposed adjacent first and second sides of the spacecraft. A first plurality of the feed horns feed the first reflector, and a second plurality of the feed horns feed the second reflector. The feed horns and offset reflectors cooperate to produce a predetermined number of beams. Even numbered beams use a set of frequencies and polarizations that are orthogonal to a set of frequencies and polarizations used by odd numbered beams. The antenna beams are contiguous in one dimension.
