Title:
STEERABLE BEAM ANTENNA
Document Type and Number:
WIPO Patent Application WO/2021/002904
Kind Code:
A3
Abstract:
A steerable beam antenna includes a plurality of semiconductor chips arranged along a longitudinal axis. Each of the chips has a ground plane on its upper surface, and is doped to form an array of semiconductor switches arranged along the longitudinal axis. A corresponding array of scattering elements, each having a first leg and a second leg, is mounted on each chip along the longitudinal axis. A first electrode of each switch is configured for connection to a control circuit, a second electrode is connected to the ground plane, and a third electrode is connected to the first leg of one of the array of scattering elements, the second leg of which is connected to the ground plane. A dielectric element is mounted on the antenna chips along the longitudinal axis above the arrays of switches and scattering elements and is separated from the scattering elements by an air gap.
