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.
