US Patent 11489573 Hybrid digital-analog mmwave repeater/relay with full duplex

A repeater for transmitting millimeter wave signals. A transceiver communicates with a plurality of remote locations over millimeter wave communications links. The of transceiver comprises a patch antenna array including a plurality of patch antennas. The plurality of patch antennas include a transmitter array portion in a first orientation for transmitting signals and a receiver array portion in a second orientation for receiving signals. The receiver array portion is vertically separated from the transmitter array portion by a predetermined distance. The first and second orientations and the predetermined distance vertically separating the transmitter array portion from the receiver array portion limit interference between the transmitted signals and the received signals. Transceiver circuitry transmits the millimeter wave signals with at least a first millimeter wave transceiver at first one of the plurality of remote locations and a second millimeter wave transceiver at a second one of the plurality of remote locations.
