Transmitter board allowing for modular antenna configurations in wireless power transmission systems
First Claim
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.

12. A method performed by a processor of a transmitter of a wireless power transmission system, the method comprising:
-
identifying, by a processor of a transmitter board having a plurality of electrical ports each configured to receive any one of a plurality of antenna boards, that a first antenna board of the plurality of antenna boards is connected to a first electrical port of the plurality of electrical ports, wherein each respective antenna board comprises antenna elements configured to transmit radio frequency (RF) power waves; selectively activating, by the processor, the first antenna board connected to the first electrical port, by instructing the transmitter board to provide, via the first electrical port, electrical signals to the first antenna board, wherein respective antenna elements of the first antenna board use the electrical signals to transmit RF power waves; and controlling, by the processor, transmission of the RF power waves via the respective antenna elements of the first 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. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
