  • Axial choke horn antenna
    Patent number: 10355359
    Abstract: An antenna includes a horn including an axial waveguide and a circular radome including a central cavity. The circular radome is configured to protrude into the axial waveguide. The antenna further includes a coil element provided over a coil frame and configured to fit inside the central cavity. The horn includes a conical structure having multiple circular chokes that are configured to shape a beam of the antenna to provide a desired gain by reducing sidelobes.

  • Dual reflector system and method for synthesizing same
    Patent number: 7006049
    Abstract: In one embodiment of the present invention, an offset folded reflector pair is optimized for scanning off boresight by enforcing the Abbe Sine condition using a least-error approximation. Coma and astigmatism compare favorably over single reflector system and Gregorian pairs over a moderate field of view. A folded-pair reflector system of the present invention offers good performance in a compact size.

  • Large instantaneous bandwidth reflector array
    Patent number: 6184839
    Abstract: A reflector for an antenna includes a plurality of reflector elements, each having a transmission line and an aperture at a distal end of the transmission line. Each transmission line having a length which varies in accordance with the position of each aperture relative to the antenna. The varying length of transmission creates a time delay that phases re-radiated waves.
