  • Apparatus and methods for reducing mutual couplings in an antenna array
    Patent number: 10135133
    Abstract: A device is presented for improving radio frequency (RF) and microwave array antenna performance. The device sits in the near field, the reactive region, of the antenna array with a pattern of electrically isolated rectangular, cross-shaped, ell, and/or similarly-shaped patches of flat metal or other conductor in a flat plane. The patches are segmented into smaller shapes no greater than 0.3 of a shortest wavelength of the nominal operating range of the antenna and/or the height of the plane is greater than 0.25 and/or less than 0.4 of the center frequency's wavelength.
    Type: Grant

    Date of Patent: November 20, 2018
    Assignee: The Chinese University of Hong Kong
    Inventors: Ke-Li Wu, Changning Wei, Xide Mei
