Modular antennas with heat sinks in wireless power transmission systems
First Claim
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.

Abstract
A wireless power transmission system includes a transmitter configured to transmit power waves including printed circuit boards where a printed circuit board 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 at least one antenna board in a pre-determined direction.

15. A method comprising:
-
providing a transmitter board with opposing first and second surfaces, the transmitter board comprising one or more electrical ports, 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, detachably connecting a first antenna board to a first electrical port of the one or more electrical ports, wherein the first antenna board comprises antenna elements configured to transmit radio frequency (RF) power waves to a receiver using electrical signals received via the first electrical port, and transmitting, by respective antenna elements of the first antenna board, RF power waves to the receiver using the electrical signals, wherein the receiver converts the received RF power waves into usable energy to power and/or charge an electronic device; and reflecting, by a heat sink attached to the first surface of the transmitter board at least some of the RF power waves transmitted by respective antenna elements of the first antenna board in a pre-determined direction. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
