Patent attributes
An antenna board for wirelessly delivering power, including a connector configured to: (i) connect with any one of a plurality of electrical ports of a transmitter board, including a first electrical port of the plurality of electrical ports, and (ii) receive an electrical signal from the first electrical port when the connector is connected with the first electrical port. The antenna board further includes antenna element(s) configured to, when the connector is connected with the first electrical port, transmit radio frequency (RF) power transmission waves using the electrical signal received from the first port. Each of the RF power transmission waves constructively interferes with at least one other RF power transmission wave of the RF power transmission waves at a receiver within a transmission field of the antenna board and energy from the RF power transmission waves is used by the receiver to power and/or charge the receiver.
