Abstract
Embodiments described herein provide for integrating a transmit phased-array (Tx) antenna and a receive phased-array (Rx) antenna onto an electrically-conductive plate that forms a ground plane. The plate includes groves that operate as an RF choke. The RF choke mitigates the energy coupling between the Tx antenna and the Rx antenna. Spatial features of the grooves are selected based on a scan angle of at least one of the Tx antenna and the Rx antenna. Due to the electronic scanning performed by the Tx antenna and the Rx antenna, the energy coupling between the Tx antenna and the Rx antenna dynamically varies and may depend upon the relative scan angles between main beams of the antennas. The energy coupling may also depend upon the side lobe energy pattern of the Tx antenna, which varies based on the scan angle of the Tx antenna.
