MOBILE COMMUNICATION DEVICE WITH WIRELESS COMMUNICATION UNIT AND WIRELESS ENERGY RECEIVER Russian patent published in 2015 - IPC H04M1/00 

FIELD: radio engineering, communication.

SUBSTANCE: mobile communication device contains the housing which accommodates the battery, the wireless communication unit and the wireless energy receiver. The wireless communication unit contains the first inductance coil used for data reception and transmission by means of inductive coupling. The wireless energy receiver contains the second inductance coil used for energy reception by means of inductive coupling. The second inductance coil is located near and above the first inductance coil. The wireless energy receiver also contains the ferrite screen located between the first inductance coil and the second inductance coil, and the compensating element located between the first inductance coil and the ferrite screen. The compensating element is implemented with a possibility of compensation of change of inductance of the first inductance coil as a result of the ferrite screen placement near it.

EFFECT: compensation of change of inductance of the inductance coil of the wireless communication unit as a result of the ferrite screen placement near it of the inductance coil of the wireless energy receiver, due to use of the compensating element between the ferrite screen and the inductance coil of the wireless communication unit.
