Wafer-Level Integrated Antenna Array For Wireless Battery Charging

Systems and methods are described for transmitting and receiving wireless power. In some embodiments, a wireless power transmission system comprises an antenna array comprising a plurality of antennas and a transceiver module configured to receive a plurality of beaconing signals via the antenna array from a wireless client during a beacon cycle. The system also comprises a controller configured to measure a phase of each of the plurality of beaconing signals and determine a transmit phase configuration for each of the antennas, and a transceiver module configured to send signals to the antenna array based on the transmit phase configuration for delivery of wireless power to the wireless client.
