Abstract

According to the present invention, a mobile terminal includes a main body including a front side with which a display unit is combined, a first antenna mounted on the main body, extended in a first direction and including a first slot of which one end is closed and another end is opened, a second antenna mounted on the main body, extended in a second direction corresponding to a direction opposite to the direction to which the first slot is extended and including a second slot of which one end is closed and another end is opened, a power supply unit mounted in the inside of the main body, a first feeder configured to supply power to the first antenna from the power supply unit and a second feeder configured to supply power to the second antenna from the power supply unit.

First claim

What is claimed is:

1. A mobile terminal, comprising:
a main body containing a front side with which a display unit is combined;
a metal plate mounted on the main body;
a connection unit coupled to one side of the metal plate;
a first conductive strip extended from the connection unit in a first direction in a manner of being separated from the metal plate with a prescribed space;
a second conductive strip extended from the connection unit in a direction opposite to the first conductive strip and positioned in a manner of being separated from the metal plate with a prescribed space;
a first antenna mounted on the main body, containing a first slot of which first end is opened and second end is closed, wherein the first slot is formed by the first conductive strip, the connection unit and the metal plate;
a second antenna mounted on the main body containing a second slot of which first end is closed and second end is opened, wherein the second slot is formed by the second conductive strip and the space between the connection unit and the metal plate;
a power supply unit;
a first feeder configured to supply power to the first antenna from the power supply unit; and
a second feeder configured to supply power to the second antenna from the power supply unit.

2. The mobile terminal of claim 1 , wherein the metal plate is positioned at a rear side of the display unit and corresponds to a part of a middle frame supporting the display unit.

3. The mobile terminal of claim 2 , wherein a middle frame further comprises an injected material integrating the metal plate, the first conductive strip and the second conductive strip with each other in a manner of using an insert injecting scheme on a circumstance of the metal plate, the first conductive strip and the second conductive strip.

4. The mobile terminal of claim 2 , further comprising:
a main board positioned at a rear side of the middle frame; and
an external terminal connection unit combined with a rear side of the main board,
wherein at least a part of the first conductive strip and the second conductive strip is positioned at a rear side of the external terminal connection unit.

5. The mobile terminal of claim 1 , wherein the metal plate, the connecting unit, the first conductive strip and the second conductive strip are integrated with each other.

6. The mobile terminal of claim 1 , wherein the first conductive strip and the second conductive strip correspond to a metal deco exposed to an exterior of the main body of the mobile terminal.

7. The mobile terminal of claim 1 , wherein the first slot and the second slot are filled with an electric insulation material.

8. The mobile terminal of claim 1 , wherein the first conductive strip and the second conductive strip correspond to a strip board containing a metallic material and wherein the connection unit comprises a screw configured to connect the strip board and a middle frame with each other.

9. The mobile terminal of claim 1 , further comprising a stub extended in a manner of being connected with at least one of the first conductive strip and the second conductive strip.

10. The mobile terminal of claim 9 , wherein the stub is positioned at a plane different from the first conductive strip or the second conductive strip.

11. The mobile terminal of claim 10 , wherein the main body comprises a front case covering a front side and a rear case covering a rear side and
wherein the stub is formed on the rear side of the rear case and connected with at least one of the first conductive strip and the second conductive strip by penetrating the rear case.

12. The mobile terminal of claim 11 , further comprising a screw connected with the stub and combined with the first conductive strip or the second conductive strip by penetrating the rear case.

13. The mobile terminal of claim 9 , wherein the first direction and the second direction are horizontal direction of the main body and wherein the stub is extended in a vertical direction along a side of the main body.

14. The mobile terminal of claim 9 , wherein the stub is arranged in a manner of being separated from the metal plate and wherein the first slot and the second slot are extended in accordance with a length of the stub.

15. The mobile terminal of claim 9 , wherein the first feeder is extended according to the first conductive strip.

16. The mobile terminal of claim 1 , further comprising:
a first coupling pattern connected with the first conductive strip and extended in the second direction; and
a second coupling pattern positioned in the vicinity of the first antenna, connected with the power supply unit extended in the first direction,
wherein end of the first coupling pattern and end of the second coupling pattern are closely arranged in a manner of facing with each other.

17. The mobile terminal of claim 1 , further comprising a switch configured to be turned on and off in a manner of being connected with the first conductive strip and the switch configured to change a flow of an electric current flowing through the first antenna.

18. The mobile terminal of claim 1 , further comprising:
a third coupling pattern extended from the second conductive strip; and
a fourth coupling pattern positioned in the vicinity of the second antenna and extended from the power supply unit.

19. The mobile terminal of claim 1 , wherein a length of the first slot is longer than a length of the second slot.
