1. A transmitter of a wireless power transmission system comprising:

  • a transmitter board comprising a plurality of electrical ports, each respective electrical port being configured to;

    receive any one of a plurality of antenna boards, andprovide electrical signals to a received antenna board, wherein each respective antenna board comprises antenna elements configured to transmit radio frequency (RF) power waves using the provided electrical signal; and

    a processor configured to;

    determine whether antenna boards of the plurality of antenna boards are connected to respective electrical ports of the plurality of electrical ports, andafter determining that a respective antenna board of the plurality of antenna boards has been received at a respective electrical port;

    instruct the transmitter board to provide, via the respective electrical port, electrical signals to the respective antenna board; and

    control transmission of RF power waves by respective antenna elements of the respective antenna board to cause each of the RF power waves to constructively interfere with at least one other RF power wave of the RF power waves at a receiver device located within a transmission field of the transmitter, wherein energy from the RF power waves is used by the receiver device to power and/or charge the receiver device.
