Abstract: A system designs a thin and relatively flat microwave focusing lens that can produce multiple simultaneous beams, using readily-available isotropic dielectric materials, and having a gradient-index (GRIN) profile. The design optimizes the lens to achieve beam scanning and/or multiple beams over a wide field of regard (FOR) with broad bandwidth and a very short focal length compared with conventional lenses. The lens can be used individually or as an element in a more complex antenna having multiple lenses in various orientations that are independently switched, selected and/or excited simultaneously as elements in a phased array. The antenna terminal incorporates such lens into an array of lenses along with one or more feeds to produce single or multiple beams covering a broad field of regard for such applications as satellite communications on-the-move, cellular, broadband point-point or point-multipoint and other terrestrial or satellite communications systems.

Abstract: A multi-band antenna system that includes a first antenna array and a second antenna array. The first antenna array includes a plurality of lens sets, each including a lens and feed element(s) configured to transmit and/or receive electromagnetic signals that pass through the lens. The second antenna array includes a plurality of antenna elements, each disposed between two of the lenses of the first array.

Abstract: An antenna beam tracking system has dynamic interference reduction. The system includes antennas that can form multiple beams, each beam of which can continually track or point its beams independently in various angular directions. A first beam continually tracks and receives (downlink) signals from a desired source or node such as a satellite or terrestrial node which generally has an apparent motion relative to the antenna. A second beam continually tracks and receives potentially harmful interference signals that may arise from different directions. The signals of the second beam are dynamically coupled to the signals in the first beam in such a manner as to effect cancellation or substantial reduction of the interference.

Abstract: A low profile mobile in-motion antenna and transmit/receive terminal system for two-way “VSAT” type satellite communication using FSS service, preferably in Ku band, supporting at the same time TV signal reception from the same satellite or a separate DBS satellite located at the same or nearby geo-stationary orbital position.
