  • Active electronically steered array for satellite communications
    Patent number: 10910702
    Abstract: An AESA for SATCOM includes a PCB; a plurality of ICs; an RF feed network for an array; a plurality of patch antennas; a SPI bus for controlling phase shifting of the ICs; phase shifters being operable for selectively introducing a phase shift internal to each of the plurality of ICs such that the radiation pattern resulting from the patch antennas connected to a single IC are steered; and wherein the plurality of ICs are operable to selectively provide either left hand circular polarization, right hand circular polarization, horizontal polarization or vertical polarization.
    Type: Grant
    Filed: July 26, 2019
    Date of Patent: February 2, 2021
    Assignee: AvL Technologies, Inc.
    Inventors: Bryan Keith Edenfield, Ian J. Timmins, Bruce Barratt, Adam Gropp, Alan E. Ellis, James L. Oliver
