Abstract

A mobile terminal including a frame having a depressed portion; a display panel positioned on a first side of the frame facing the display panel; and a short range antenna disposed in the depressed portion and between the frame and the display panel and having a radiation direction toward the display panel.

Claims

1. A mobile terminal comprising:

a display panel;

a printed circuit board;

a frame having a first surface supporting the display panel and a second surface facing the printed circuit board;

a back cover coupled to the frame to cover a battery and formed of a metal;

a short range antenna disposed on the first surface of the frame and disposed between the frame and the display panel and having a radiation direction toward an opposite direction to the metal; and

the battery disposed on a portion of the second surface opposite to the first surface,

wherein the frame has a first depressed portion recessed from a portion of the first surface of the frame and a second depressed portion within the first depressed portion and being recessed from the first depressed portion,

wherein the short range antenna is disposed within the second depressed portion,

wherein the frame has a first portion overlapped with a portion of the printed circuit board and including the second depressed portion, and a second portion where the battery is disposed on,

wherein at least part of the display panel, the short range antenna, the frame and the printed circuit board are stacked sequentially in a region where the second depressed portion of the frame is formed, and the short range antenna radiates a short-range communication signal toward the display panel,

wherein the short range antenna is disposed on a flexible printed circuit board, and

wherein the display panel and the flexible printed circuit board are disposed at the first depressed portion.

2. The mobile terminal of claim 1, wherein the frame includes a metal material.

3. The mobile terminal of claim 1, further comprising:

a shielding layer disposed between the frame and the short range antenna.

4. The mobile terminal of claim 1,

wherein the flexible printed circuit board electrically connects the display panel to a controller, and

wherein the short range antenna is disposed on the flexible printed circuit board and is electrically insulated from the flexible printed circuit board.

5. The mobile terminal of claim 4, further comprising:

a substrate including at least one electronic element, the substrate being on the second surface of the frame,

wherein the controller is mounted on the substrate.

6. The mobile terminal of claim 5, wherein the flexible printed circuit board electrically connects the display panel to the controller, and

wherein the short range antenna extends from the flexible printed circuit board.

7. The mobile terminal of claim 1, wherein the short range antenna is disposed in the second depressed portion corresponding to an upper portion of the display panel when the display panel is in a portrait view.

8. The mobile terminal of claim 1, wherein the short range antenna is disposed in the second depressed portion corresponding to a central portion of the display panel.

9. The mobile terminal of claim 1, wherein the short range antenna is disposed in the second depressed portion corresponding to an outer portion of the display panel.

10. The mobile terminal of claim 1, wherein the short range antenna includes one wire and forms a winding on different planes.

11. The mobile terminal of claim 10, wherein the short range antenna includes a first coil and a second coil, which is connected to the first coil and is formed on a plane different from the first coil.

12. The mobile terminal of claim 11, wherein the first coil and the second coil have a loop shape, and

wherein the first and second coils of the loop shape form at least one turn.

13. The mobile terminal of claim 11, wherein the second coil is connected to the first coil and is formed at a height different from the first coil in a thickness direction of the mobile terminal.

14. The mobile terminal of claim 1, wherein the short range antenna comprises a near field communication antenna.

15. The mobile terminal of claim 1, further comprising:

a controller configured to control the short range antenna to transmit payment information to an external payment terminal in response to the mobile terminal being with a short range from the external payment terminal.

16. The mobile terminal of claim 1, wherein the mobile terminal comprises a smart watch.

17. The mobile terminal of claim 1, wherein the short range antenna is formed on the flexible printed circuit board such that the a portion of flexible printed circuit board is also disposed in the second depressed portion and the short range antenna faces the display panel.

18. The mobile terminal of claim 17, wherein the second depressed portion is formed at a position of the frame corresponding to an upper portion of the display panel when the display panel is in a portrait view.

19. The mobile terminal of claim 18, wherein the flexible printed circuit board extends lengthwise under the display panel and connects to a lower portion of the display panel and also passes through an opening in the frame to connect to a lower portion of a printed circuit board disposed below the frame.
