WIRELESS CHARGING OF METAL BACKED ELECTRONIC DEVICES

摘要

A method and system for providing wireless power transfer through a metal object by forming a loop conductor from the metal object through a feature or component embedded within the metal object and by replacing portions of the metal object with insulating components. The method and system utilize a recessed channel (610) to install and isolate conductors (616) that are connected to transmitter or receiver circuits and enable wireless power transfer and other communications. The recessed channel creates a loop around at least a portion of the metal object (604) such that the conductor installed therein may form a loop conductor, which may be connected to a source or sink. In some implementations, a logo embedded within the metal object may create a loop formed by the metal object with a current path around the logo, wherein the metal object itself may be configured to operate as the conductor.
