To provide a satellite reflection antenna system where each antenna beam demarcates individual arrival range cell in a beam arrival range and, antenna feeds, a sub reflector and a main reflector are placed and oriented so that each antenna beam nearly symmetrically shaped is supplied adjacent over the arrival range on the basis of the global scale.
A feed array 22 includes a plurality of feeds that are coupled with a feed network acting like combining radiation beams of a pre-selected feed number so as to produce a plurality of composite radiation beams 23 shaped to have a prescribed contour. Each composite radiation beam is oriented to be made incident on each predetermined location of a sub reflector 27 that orients the radiation beams to a main reflector 25 and the main reflector reflects each composite radiation beam in a pre-selected direction.
