Electronic device
A mobile terminal including a display unit including a window glass and a display module; a front case and a rear case configured to support the display unit; an antenna including a first coil formed on an edge region of a rear surface of the window glass or formed on an edge region of a front surface of the front case, a second coil formed at a height different from that of the first coil in a thickness direction of the mobile terminal, and a conductive hole configured to electrically connect the first coil and the second coil; a battery configured to supply power to the mobile terminal; and a battery cover positioned on a back side of the display unit and including a metal.
1. A mobile terminal, comprising:
a window glass;
a display module positioned behind the window glass;
a case positioned behind the display module;
a first electrode connected to a rear surface of the window glass and connected to a front surface of the case;
a second electrode connected to the rear surface of the window glass, connected to the front surface of the case, and adjacent to the first electrode;
a first coil formed on the rear surface of the window glass and electrically connecting the first electrode and the second electrode; and
a second coil formed on the front surface of the case and electrically connecting the first electrode and the second electrode.
2. The mobile terminal of claim 1 , wherein the first coil is positioned in an outer region of the display module.
3. The mobile terminal of claim 1 , wherein the first coil and the second coil have a loop shape, and form at least one turn.
4. The mobile terminal of claim 1 , wherein the first coil surrounds the display module.
5. The mobile terminal of claim 4 , further comprising:
a printed circuit board (PCB) electrically connected to the first coil or the second coil and configured to transmit and receive an electrical signal to and from the first coil and the second coil.
6. The mobile terminal of claim 1 , further comprising:
a flexible printed circuit board (FPCB) configured to connect a lower portion of the display module,
wherein the first coil is electrically connected to the FPCB in at least one portion thereof.
7. The mobile terminal of claim 1 , further comprising:
a speaker positioned in at least a portion of the case.
8. The mobile terminal of claim 7 , wherein the second coil is positioned in an outer region of the speaker.
9. The mobile terminal of claim 7 , wherein the second coil is positioned on a plane perpendicular to a plane on which the first coil is positioned.
10. The mobile terminal of claim 7 , wherein the case further includes a speaker housing configured to protect the speaker, and
wherein the second coil enfolds a side surface of the speaker housing.
11. The mobile terminal of claim 1 , wherein the second coil is positioned in a lower end portion of a rear surface of the display module.
12. The mobile terminal of claim 1 , further comprising:
a printed circuit board (PCB) configured to transmit and receive an electrical signal to and from the first and second coils,
wherein the second coil is positioned on the PCB.
13. The mobile terminal of claim 1 , wherein the case includes an edge frame and center frame,
wherein the center frame supports the display module, and
wherein the second coil is formed on an upper surface of the edge frame.
14. The mobile terminal of claim 1 , further comprising:
a battery configured to supply power to the mobile terminal; and
a battery cover positioned on a back side of the display module and including a metal.
15. The mobile terminal of claim 1 , wherein a first area surrounded by the first coil is larger than a second area surrounded by the second coil.
16. The mobile terminal of claim 15 , wherein the first area and the second area face each other.
