1. A wireless power receiver comprising:

  • a flexible printed circuit board comprising a first surface and a second surface opposite the first surface;

    a first antenna disposed on the first surface of the flexible printed circuit board for wireless charging;

    a second antenna disposed on the first surface of the flexible printed circuit board for wireless communication such that it surrounds the first antenna;

    a plurality of contact terminals configured to electrically connect the first antenna to a battery for charging the battery and the second antenna to a wireless communication module; and

    a magnetic sheet on the first antenna and the second antenna;

    wherein the first antenna comprises a first coil pattern wound multiple times, a first terminal placed at an outside of the first coil pattern, and a second terminal placed at an inside of the first coil pattern;

    wherein the second antenna comprises a second coil pattern wound multiple times, a third terminal placed at an inside of the second coil pattern, and a fourth terminal placed at an outside of the second coil pattern;

    wherein the first terminal is electrically connected to a first connector by a first sub-connection part that crosses, and is physically insulated from, the second coil pattern, and the first sub-connection part is disposed on the second surface of the flexible printed circuit board;

    wherein the second terminal is electrically connected to a second connector by a second sub-connection part that crosses, and is physically insulated from, both the first coil pattern and the second coil pattern, and the second sub-connection part is disposed on the second surface of the flexible printed circuit board;

    wherein the plurality of contact terminals comprises a first contact terminal and a second contact terminal that connect the first antenna and the battery for charging the battery;

    wherein the first connector is electrically connected to the first contact terminal by a first connection conductive line, and the first connection conductive line is disposed on the first surface of the flexible printed circuit board;

    wherein the second connector is electrically connected to the second contact terminal by a second connection conductive line, and the second connection conductive line is disposed on the first surface of the flexible printed circuit board;

    wherein the first antenna and the second antenna are disposed between the magnetic sheet and the flexible printed circuit board;

    wherein the plurality of contact terminals comprises a third contact terminal and a fourth contact terminal that connect the second antenna and the wireless communication module;

    wherein the first, second, third, and fourth contact terminals are disposed as a 2×

    2 matrix;

    wherein the first contact terminal and the second contact terminal are disposed on a first line in the 2×

    2 matrix and the third contact terminal and the fourth contact terminal are disposed on a second line in the 2×

    2 matrix;

    wherein the third terminal is electrically connected to the third contact terminal by a third sub-connection part physically insulated from the second coil pattern;

    wherein the fourth terminal is electrically connected to the fourth contact terminal by a fourth sub-connection part physically insulated from the second coil pattern; and

    wherein a first line connecting the first terminal and the first contact terminal through the first sub-connection part, the first connector and the first connection conductive line, and a second line connecting the second terminal and the second contact terminal through the second sub-connection part, the second connector and the second connection conductive line are disposed between the third terminal and the fourth terminal.
