  • Radiation assembly, waveguide antenna sub-array, and waveguide array antenna
    Patent number: 11831081
    Abstract: The present disclosure relates to a radiation assembly, a waveguide antenna sub-arrays, and a waveguide array antenna. The radiation assembly for the waveguide array antenna comprises: a first radiation layer having a plurality of first radiation windows, each of the plurality of first radiation windows has a metal grid that divides the corresponding first radiation window into two radiation holes; and a second radiation layer having a plurality of second radiation windows, the plurality of second radiation windows has a one-to-one correspondence with the plurality of first radiation windows, and the plurality of second radiation windows of the second radiation layer do not have a metal grid. The thickness of the second radiation layer is greater than the thickness of the first radiation layer, and the first radiation layer and the second radiation layer are manufactured independently of each other.
    Type: Grant

  • Microwave antennas for extremely low interference communications systems
    Patent number: 9835664
    Abstract: Microwave antennas having optimized performance are provided. The microwave antennas include a primary reflector having effective foci arranged in a generally circular or elliptic range around a central axis thereof, and a matching component filling a hole at a bottom center portion thereof. The structural parameters of the microwave antenna are tuned by an aperture field analysis method to optimize the overall performance.
