First Claim
Patent Images
1. A device, comprising:
- a housing for receiving an electronic device having at least one receive antenna; and
at least one parasitic antenna coupled to the housing and to couple with a near field generated by a transmit antenna and enhance the near field about the at least one parasitic antenna with an enhanced near field coupling mode region stronger than a near field coupling mode region of the transmit antenna.

Abstract
Exemplary embodiments are directed to wireless power transfer. A method may include wirelessly receiving power from a near field in a first near field coupling mode region with at least one parasitic antenna coupled to a housing having a chargeable device positioned therein. The method may further include generating an enhanced near field from the near field with the at least one parasitic antenna and wirelessly receiving power from the enhanced near field at an at least one receive antenna coupled to the chargeable device.
