  • Patent number: 10854994
    Abstract: A broadband phased array antenna system is set forth comprising a support member; an antenna array mounted to the support member, the antenna array having a plurality of uniformly excited hybrid radiating elements arranged in a symmetric array on a substrate; a baseband controller mounted to the support member; a radio controller mounted to the support member for modulating and demodulating signals between the baseband controller and antenna array; and a communications interface for removably connecting and disconnecting the antenna system. In one aspect, the antenna array comprises a substrate; a plurality of uniformly excited hybrid radiating elements arranged in a symmetric array on the substrate; a hybrid feeding network for transmitting RF-signals to the hybrid radiating elements; and artificial materials surrounding opposite sides of the symmetric array for suppressing edge scattered fields and increasing gain of the antenna system.

  • Patent number: 9257735
    Abstract: An antenna apparatus comprises a lower assembly and an upper assembly, which together forming a cavity to contain an RF circuit device. The upper assembly comprises a waveguide flange interface at an external surface of the upper assembly. The waveguide flange interface comprises a waveguide channel extending from the external surface to an internal surface forming a surface of the cavity. An opening of the waveguide channel at the internal surface is substantially centered about a first centerline of the upper assembly parallel with the external surface and offset from a second centerline of the upper assembly parallel with the external surface, whereby the second centerline perpendicular is to the first centerline. The upper assembly is removably attachable to the lower assembly in either of a first orientation or a second orientation, whereby the second orientation represents a 180 degree rotation of the upper assembly relative to the first orientation.
