Antenna structure and electronic device including same

1 . An electronic device comprising:

a battery;

a main circuit board operatively connected to the battery; and

an antenna structure operatively connected to the main circuit board, the antenna structure including:

a base board disposed above the battery;

a wireless charging coil disposed on the base board, and comprising a first wound part including a first end portion and a second end portion and a second wound part wound inward from a third end portion to a fourth end portion, wherein the first wound part is wound around the second wound part; and

a first flexible printed circuit board (FPCB) configured to electrically connect the first end portion of the first wound part and the third end portion of the second wound part to the main circuit board; and

a conductive member disposed on the base board and being overlapped with a portion of the second wound part, the conductive member electrically connecting the second end portion of the first wound part and the fourth end portion of the second wound part, and

a second flexible printed circuit board (FPCB) extending through a gap between the battery and the base board, wherein the conductive member does not overlap with the second FPCB.

2 . The electronic device of claim 1 , wherein the first coil wound part is extended in a first rotation direction from the first end portion toward the second end portion, and

wherein the second wound part is extended in a second rotation direction from the third end portion toward the fourth end portion, the second rotation direction being opposite to the first rotation direction.

3 . The electronic device of claim 1 , wherein the first wound part extends in a first rotation direction from the first end portion toward the second end portion,

wherein the second wound part extends in the first rotation direction from the fourth end portion toward the third end portion, and

wherein the second wound part has a shape wound at least twice.

4 . The electronic device of claim 1 , further comprising a display,

wherein the second FPCB is electrically connected to the display.

5 . The electronic device of claim 4 , wherein the conductive member is not overlapped with the second FPCB in a thickness direction of the electronic device.

6 . The electronic device of claim 1 , further comprising a heat dissipation sheet between the battery and the base board.

7 . The electronic device of claim 6 , wherein at least a portion of the heat dissipation sheet is disposed between the battery and the conductive member in a thickness direction of the electronic device.

8 . The electronic device of claim 1 , wherein each of the first wound part and the second wound part includes a conductive pattern on a surface of the base board.

9 . The electronic device of claim 1 , wherein the antenna structure further comprises a third wound part outside the first wound part and the second wound part.

10 . The electronic device of claim 9 , wherein the third wound part includes a conductive pattern on a surface of the base board.

11 . The electronic device of claim 1 , further comprising a shielding sheet between the battery and the base board.

12 . The electronic device of claim 1 , further comprising:

a sub-circuit board; and

a third FPCB electrically connected to the main circuit board and the sub-circuit board.

13 . The electronic device of claim 12 , wherein the conductive member is not overlapped with the third FPCB in a thickness direction of the electronic device.

14 . The electronic device of claim 1 , wherein the conductive member is overlapped with at least the portion of the second wound part in a thickness direction of the electronic device.

15 . The electronic device of claim 14 , wherein the conductive member is disposed to cross the at least the portion of the second wound part.

16 . The electronic device of claim 1 , wherein the first wound part has a semi-circle shape, and

wherein the second wound part has a spiral shape.
