An apparatus for wireless power reception in an electronic device may include a casing configured to house electronic components of the electronic device. The casing may include a non-conductive support substrate and a metal layer disposed on the support substrate. The apparatus may include a power receiving element configured to magnetically couple to an externally generated magnetic field to produce power for one or more of the electronic components of the electronic device.

Wireless power transfer using direct field penetration through a metal object

Disclosed is a wireless power transfer apparatus that includes a case for an electronic device. The case may have an electrically conductive panel portion and side portions defined along sides of the panel portion. The case further have at least one opening formed one of the side portions. A coil configured to couple to an externally generated magnetic field may have first segments that span a width of the panel portion of the case and second segments arranged along the side portions of the case and exposed through the at least one opening.

Multi-turn coil on metal backplate

This invention describes a method and apparatus to cancel the mutual inductance between mutually coupled transmit coils, each of the transmit coils fed by individual power amplifiers, and the transmit coils all sharing a common ground with the power amplifiers. The methods and systems disclosed consist of coupling the return legs of each transmit coil to a mutual inductance cancellation circuit near a common ground return connection. The cancellation circuit uses a combination of inductors and capacitors to bridge various combinations of the transmit coils without physically connecting the 'bridged' transmit coils. Transmit coils 'bridged' using inductors have positive mutual inductance added to them, while transmit coils &#x201c;bridged&#x201d; using capacitors have negative mutual inductance added to them. Additionally, manipulation of the transmit coil overlap of overlapping transmit coils and/or manipulation of the location of the cancellation circuit can be used finely tune the mutual inductance between the transmit coils.
