  • Aperiodic phased array antenna with single bit phase shifters
    Patent number: 10553946
    Abstract: An antenna array can include multiple radiating cells, each comprising a radiating element and a phase shifter. Further, each radiating element can comprise a first radiating element port and a second radiating element port. Each of the radiating cells can be configured to selectively connect the phase shifter to one of the radiating element ports. Each of the radiating cells can further comprise a phase delay difference between the signal paths associated with the radiating element ports. Further, the radiating cells can have physical polarization orientations that can be different from at least one other radiating cell.
    Type: Grant
    Filed: May 3, 2019
    Date of Patent: February 4, 2020
    Assignee: Viasat, Inc.
