发明名称 Multi-beam antenna communication system and method
摘要 A communication system and method for reconfigurably transmitting and receiving signals via a multi-beam reflector antenna array are disclosed. The multi-beam antenna system comprises a plurality of rings of single beam reflectors, each reflector having its own feed, wherein the plurality of rings are substantially concentric or nested and disposed on separate planes such that the reflectors of adjacent rings are substantially interleaved. The method, in one embodiment, comprises generating beams from a first, second and third ring of single beam feeds, respectively reflecting each beam from the first, second and third ring of single beam feeds on a separate reflector to a substantially separate coverage area, wherein the first, second and third rings are substantially concentric and disposed on separate planes such that the reflectors of adjacent rings are substantially interleaved.
