The disclosure relates to a method, apparatus and system to wirelessly charge a device. Specifically, the disclosed embodiments provide improved charging stations for increased active charging area. In one embodiment, the disclosure relates to an offset device for use with a Power Receiving Unit (PRU). The offset device includes a conductive layer supporting an aperture, the aperture aligned with an inner most coil loop of the PRU; and a first slot formed in the conductive layer extending from the aperture to an outside edge of the conductive layer.

Method and apparatus for coil integration for uniform wireless charging

Techniques for focusing the energy radiated by a wireless power transmitting unit are described. An example power transmitting unit includes a transmitter coil configured to generate a magnetic field to wirelessly power a device within an active wireless charging area. The power transmitting unit also includes a power generating circuitry to deliver current to the transmitter coil to generate the magnetic field. The power transmitting unit also includes a shield disposed around the transmitter coil to reduce the strength of the magnetic field outside of the active wireless charging area.
