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.
