Abstract
A mobile communication device having a wireless power receiver and wireless communications unit, in which inductors of the communications unit and the power receiver are in close proximity to each other, is provided. The mobile communication device includes a wireless communications unit including a first inductor configured to transmit and receive data via inductive coupling, and a wireless power receiver. The wireless power receiver includes a second inductor which is disposed above the first inductor and receives power via inductive coupling, a ferrite shield disposed between the first inductor and the second inductor, and a compensator disposed between the first inductor and the ferrite shield. Compensator is adapted to compensate for variations in the inductance of the first inductor caused by the ferrite shield.
