摘要： A thinned multiple beam phased array antenna which includes, in a sending array configuration, an antenna element, beam forming network, feeding circuits, a phase and gain controller, and a phase control algorithm storage unit. A feeding circuit is coupled to an associated antenna element and the beam forming network, and passes a beam forming signal between the antenna element and the beam forming network. The antenna element preferably includes a plurality of radiators and a plurality of band pass filters, wherein a band pass filter is dedicated to each radiator. The beam forming network preferably includes a stripline power divider and a power distributor. The feeding circuits preferably include a plurality of impedance-matching isolators, a plurality of solid state power amplifiers, a plurality of n:1 signal combiners, a plurality of monolithic microwave integrated circuits (MMICs), and a plurality of phase shifters. This configuration is integrated into a single system which provides flexibility of beam placement, narrow beam width, simultaneous, independent multiple beams and reduces the overall system weight and cost.

摘要： An antenna element and beamforming network (10) preferably comprises a plurality of radiators (12), a plurality of band pass filters (14) and a plurality of test couplers (16). Each radiator (12) is coupled to a dedicated MMIC (18). The output of MMICs (18) are coupled to a power stripline combiner (20) to provide a single output. Each of MMICs (18) is independently controllable to shape the antenna beams as desired for producing nulls in pattern coverage. The output of stripline combiner (20) may also be coupled through an output test coupler (46) to a jammer detector and correlator (24). In one embodiment, radiators (12) are horns that include filters (14). The output of each horn is coupled to the input of its dedicated MMIC (18). In another embodiment, radiators (12) are a patch array coupled together by a stripline combiner. The output of the stripline combiner is coupled by band pass filter (14) to the input of the respective MMICs (18). The present invention integrates these components into a single package with reduced size and weight.
