Abstract
A wireless power transmission system is disclosed. In one aspect, the system includes a transmitting antenna configured to transmit power, via a magnetic field, to a receiving antenna to power a load. The system also includes a tuning loop electrically isolated from the transmitting antenna and being movable relative to the transmitting antenna to adjust a coupling between the transmitting antenna and the tuning loop.
Claims21
A wireless power transmission system, comprising:
- a transmitting antenna configured to transmit power, via a magnetic field, to a receiving antenna to power a load;
- and
- a tuning loop electrically isolated from the transmitting antenna and being movable to adjust a coupling between the transmitting antenna and the tuning loop.
A method of transmitting power, comprising:
- transmitting power, via a magnetic field, from a transmitting antenna to a receiving antenna to power a load, the transmitting antenna electrically isolated from a tuning loop;
- and
- moving the tuning loop to adjust a coupling between the transmitting antenna and the tuning loop.
A wireless power receiver, comprising:
- a receiving antenna configured to receive power, via a magnetic field, from a transmitting antenna to power a load;
- and
- a tuning loop being electrically isolated from the receiving antenna and being movable relative to the receiving antenna to adjust a coupling between the receiving antenna and the tuning loop.
