  • Patent number: 12148996
    Abstract: A slot array antenna includes a waveguide and a horn. The waveguide has a first surface including multiple slots arranged along a longitudinal direction of the first surface to radiate radio waves. The width of the first surface in the lateral direction is greater than half of a wavelength of the radio waves. The horn, fixedly attached to the waveguide, enlarges towards a radiation direction of the radio waves. The horn has upper and lower portions bent inwards twice with respect to a lateral direction of the first surface to form first and second narrow openings. An opening width of the first narrow opening is less than the width of the first surface. An opening width of the second narrow opening is less than or equal to two fifth of the wavelength. Thus, a side lobe generated due to horizontal polarization of the radio waves is suppressed.

  • Patent number: 12046829
    Abstract: A method and system are provided for aligning signals in a phased array system having multiple tiles. Tile-to-tile signal alignment is achieved through the use of internally-generated local oscillator signals and existing coupling paths between transmit and receive antenna elements in adjacent tiles of the phased array system. The relative phases of the local oscillator signals are measured in both directions between adjacent tiles to determine phase differences that can then be used for alignment of the signals between the adjacent tiles. The self-alignment process can then be repeated on subsequent adjacent tile pairs, thus providing a fully aligned and phase-balanced phased array system. Because there is no need for any external signals or components that are not already resident on the tiles, self-alignment can be performed as part of system startup, e.g., to align the multi-tile phased array before the system is placed into operation in a live network.
