Abstract
A method and apparatus for reconfigurably transmitting shaped beam satellite signals via reflector array antennas are disclosed. The apparatus comprises a reflector for reflecting RF signals having a reflector focal plane and a feed array comprising a plurality of feed elements wherein said feed array is defocused from said reflector focal plane, yet produces a wavefront substantially similar to a wavefront that would be produced by a feed array located at the reflector focal plane. The method of transmitting a signal in accordance with the present invention comprises forming a wavefront with a feed array, wherein said feed array is defocused from a reflector focal plane, yet produces a wavefront substantially similar to a wavefront that would be produced by a feed array located at the reflector focal plane and reflecting said wavefront to a coverage area.
