Shared antenna arrays with multiple independent tilt

An antenna, comprising:

• a. a feed network, having;
• 1. a first RF input for a first sub-band coupled to a first sub-band tilt control;
• 2. a second RF input for a second sub-band coupled to a second sub-band tilt control, the second sub-band tilt control being controllable independently with respect to the first sub-band tilt control;
• 3. a combiner network including a first diplexer coupled to first outputs of the first and second sub-band tilt controls and a second diplexer coupled to the outputs of the first and second, sub-band tilt controls, the combiner network further having a first branchline hybrid coupled to the first diplexer common port and a second branchline hybrid coupled to the second diplexer common port, 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
• 4. a beamforming network, the beamforming network coupled to the combiner network and having a plurality of RF outputs;
• and
• b. an array of radiating elements, the radiating elements being coupled to the RF outputs.
