MODULAR ANTENNAS IN WIRELESS POWER TRANSMISSION SYSTEMS
A wireless power transmission system includes a transmitter configured to transmit power waves including printed circuit boards and antenna boards, where each antenna board comprises one or more antenna elements, at least one antenna board resides on a printed circuit board, and the at least one antenna board is connected with a power feeding line. The transmitter further includes a heat sink attached to the at least one printed circuit board, wherein placement of the heat sink with respect to the at least one antenna board comprising the one or more antenna elements and shape of the heat sink is configured such that the heat sink operates as a reflector to direct wireless power waves transmitted from the one or more antenna elements of the at least one antenna board in a pre-determined direction.
