1. A transmitter in a wireless power transmission system, the transmitter comprising:

  • a transmitter board with opposing first and second surfaces, the transmitter board comprising one or more electrical ports on the first surface, each of the one or more electrical ports being configured to receive electrical signals from the transmitter board and provide the electrical signals to an antenna board;

    one or more antenna boards, each antenna board comprising antenna elements configured to transmit radio frequency (RF) power waves to a receiver using the electrical signals from a respective electrical port of the one or more electrical ports, wherein;

    each of the one or more antenna boards is configured to removably connect to any one of the one or more electrical ports of the transmitter board; and

    the receiver is configured to convert the received RF power waves into usable energy to power and/or charge an electronic device; and

    a heat sink attached to the first surface of the transmitter board, the heat sink being configured to;

    absorb heat generated by the transmitter board, andreflect at least some of the RF power waves transmitted by the one or more antenna boards in a pre-determined direction.
