  • Beam steering in sub-arrayed antennae
    Patent number: 6661375
    Abstract: A method is presented for operating a phased array antenna comprising a number of sub-arrays. The method comprises the steps of introducing phase offsets into signals received from/transmitted to each element in the antenna, to provide directional transmit or receive sensitivity in a first direction; summing signals received from each element in each sub-array to provide respective sub-array signals; introducing respective phase offsets into the respective sub-array signals to adjust the direction of maximum sensitivity within a sensitivity envelope defined by the phase offsets applied to each element of the antenna as a whole.
    Type: Grant
    Filed: February 15, 2002
    Date of Patent: December 9, 2003
    Assignee: Roke Manor Research Limited
