Patent ID: 7242360

Claim:
An antenna system comprising: a main reflector having a parabolic dish shape with a concave reflective surface; a sub-reflector disposed above and spaced apart from the concave reflective surface of the main reflector with a first focal point aligned with a focal point of the main reflector; a first feedhorn cluster that includes a plurality of first feedhorns operative to transmit and receive radio frequency signals within a first frequency band, the first feedhorn cluster extends through the concave reflective surface with its radiating aperture's phase center substantially aligned with a second focal point of the sub-reflector, wherein the plurality of first feedhorns distribute the total power of an output signal through spatial combining of the plurality of feedhorns; and a second feedhorn cluster that includes a plurality of second feedhorns operative to transmit and receive radio frequency signals within a second frequency band, the second feedhorn cluster extends through the concave reflective surface with its radiating aperture's phase center substantially aligned with the second focal point of the sub-reflector.
