Modular antenna boards in wireless power transmission systems
First Claim
1. An antenna board for wirelessly delivering power to a receiver device, the antenna board comprising:
- a connector configured to;
detachably 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, andreceive an electrical signal from the first electrical port when the connector is connected with the first electrical port; and
one or more antenna elements 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 electrical port, wherein;
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 device within a transmission field of the antenna board; and
energy from the RF power transmission waves is used by the receiver device to power and/or charge the receiver device.

Abstract
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.

11. A method of wirelessly delivering power to a receiver device, the method comprising:
at an antenna board comprising a connector and one or more antenna elements; connecting, via the connector, the antenna board to a first electrical port of a transmitter board, wherein the transmitter board includes a plurality of electrical boards, including the first electrical port; after connecting the antenna board to the first electrical port; receiving an electrical signal from the first electrical port; transmitting, via the one or more antenna elements, radio frequency (RF) power transmission waves using the electrical signal received from the first electrical port, wherein; 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 device within a transmission field of the antenna board; and energy from the RF power transmission waves is used by the receiver device to power and/or charge the receiver device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
