Patent ID: 7110716

Claim:
A multiple beam antenna system comprising: a set of reflectors common to both a downlink frequency band and an uplink frequency band, said set of reflectors generating a plurality of beams in a cell reuse pattern; at least one dual-band frequency-dependent horn feeding said set of reflectors, said downlink frequency having a phase center in said horn that is separated from a phase center of said uplink frequency by a predetermined distance, said downlink phase center of said at least one dual-band frequency dependent horn being close to a focal point of at least one reflector in said set of reflectors, said uplink phase center of said at least one dual-band feed horn being positioned away from a focal point of said at least one reflector; said horn illuminating at least one reflector in said set of reflectors at said downlink frequency while under illuminating at least one reflector in said set of reflectors at said uplink frequency.
