Mobile communication device with wireless communications unit and wireless power receiver
First Claim
1. A mobile communication device comprising:
- a wireless communications device configured to transmit and receive data using a first inductor;
a wireless power receiver configured to receive power wirelessly using a second inductor disposed above the first inductor;
a shield for magnetic shielding configured to be disposed between the first inductor and the second inductor; and
a compensator configured to;
be disposed between the first inductor and the shield, andcompensate for inductance of the first inductor,wherein the compensator compensates the inductance of the first inductor to an initial value by generating a magnetic field having a direction opposite to a magnetic field generated by the first inductor.

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.
