WIRELESS POWER TRANSMISSION FOR ELECTRONIC DEVICES
First Claim
1. An apparatus for wireless power transfer, comprising:
- an antenna circuit; and
a power circuit coupled to the antenna circuit and configured to;
selectively drive the antenna circuit to output wireless power at a first level sufficient to charge or power a first load; and
selectively provide to a second load power received by the antenna circuit via a wireless field at a second level sufficient to power or charge the second load.

Abstract
Exemplary embodiments are directed to wireless power transfer. A wireless power receiver includes a receive antenna for coupling with a transmit antenna of transmitter generating a magnetic near field. The receive antenna receives wireless power from the magnetic near field and includes a resonant tank and a parasitic resonant tank wirelessly coupled to the resonant tank. A wireless power transmitter includes a transmit antenna for coupling with a receive antenna of a receiver. The transmit antenna generates a magnetic near field for transmission of wireless power and includes a resonant tank and a parasitic resonant tank coupled to the resonant tank.
