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.

An antenna system for use on a spacecraft, comprising:
- first and second offset reflectors disposed adjacent first and second sides of the spacecraft;
- a predetermined number of feed horns, comprising a first plurality of feed horns that feed the first reflector, and a second plurality of feed horns that feed the second reflector;
- the feed horns and first and second offset reflectors cooperating to produce a predetermined number of beams that are contiguous in one dimension;
- and wherein 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.
An antenna system for use on a spacecraft, comprising:
- first and second offset reflectors disposed adjacent first and second sides of the spacecraft;
- eight feed horns, four of which feed the first reflector, and four of which feed the second reflector;
- the feed horns and first and second offset reflectors cooperating to produce eight beams that are contiguous in one dimension;
- and wherein 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.
