Abstract
A method and system for providing power to a chargeable device via radio frequency link are provided. In one aspect, a method of providing power to a chargeable device via radio frequency link comprises generating a substantially unmodulated signal. The method further comprises radiating a substantially unmodulated radio frequency (RF) signal to the chargeable device via a transmit antenna based on the substantially unmodulated signal. The method further comprises powering or charging the chargeable device with power delivered by the substantially unmodulated RF signal.
Claims54
A system configured to provide power to a chargeable device via radio frequency link, the system comprising:
- a transmitter configured to generate a substantially unmodulated signal for powering or charging the chargeable device;
- and
- a transmit antenna configured to receive the substantially unmodulated signal from the transmitter and radiate a substantially unmodulated radio frequency (RF) signal to the chargeable device.
A system configured to provide power to a chargeable device via a radio frequency link, the system comprising:
- a first transmitter configured to transmit a first signal via a first antenna for powering or charging the chargeable device;
- and
- a second transmitter configured to transmit a second signal via a second antenna for powering or charging the chargeable device,
- wherein the combination of the first and second signals power or charge the chargeable device.
The system of 18, wherein each of the first and second signals comprises a substantially single frequency signal.
A method of providing power to a chargeable device via radio frequency link, the method comprising:
