  • Reconfigurable reflectarry for passive communications
    Patent number: 11289817
    Abstract: A reconfigurable reflectarray antenna (RAA) system includes a reconfigurable RAA and a controller. The RAA includes a metasurface having a dynamically tunable electromagnetic characteristic and is configured to receive a signal of opportunity. The signal of opportunity is generated separately and independently from the reconfigurable RAA system. The controller is in signal communication with the reconfigurable RAA and is configured to generate a control signal configured to dynamically tune the electromagnetic characteristic of the metasurface. The electromagnetic characteristic includes a reflection phase, which when varied, dynamically beam steers the signal of opportunity reflected from the metasurface.
