Claim Text:
1. A feed network for use with an antenna array, comprising: a. a first RF input for a first sub-band signal coupled to a first sub-band parameter control; b. a second RF input for a second sub-band signal coupled to a second sub-band parameter control; c. a combiner network having a first diplexer coupled to first outputs of the first and second sub-band parameter controls and a second diplexer coupled to second outputs of the first and second sub-band parameter controls, the combiner network also having a branchline hybrid having a first input coupled to the first sub-band parameter control and a second input coupled to the second sub-band parameter control, the combiner network also having at least one output comprising a combination of the first sub-band signal and the second sub-band signal; and d. a beamforming network, the beamforming network coupled to outputs of the branchline hybrid of the combiner network and having a plurality of RF outputs; wherein the first and second sub-band parameter controls are independently adjustable and wherein adjustment of the first and second sub-band parameter controls independently adjusts a down-tilt of first and second sub-band beams.
