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 case forming an exterior of the mobile terminal and comprising a first conductive strip and a second conductive strip;
a display placed on the front surface of the case;
a metal plate placed on a rear surface of the display;
a first antenna formed by the first conductive strip and the metal plate;
a second antenna formed by the second conductive strip and the metal plate;
non-conductive material filling a space between metal plate and the first conductive strip, and the metal plate and the second conductive strip;
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,
wherein a length of the first conductive strip is longer than a length of the second conductive strip, and
wherein a resonant frequency of the first antenna is lower than a resonant frequency of the second antenna.

2. The mobile terminal of claim 1 , further comprising a connection unit to couple the metal plate to at least one of the first conductive strip and the second conductive strip.

3. The mobile terminal of claim 2 , 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.

4. The mobile terminal of claim 3 , 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 non-conductive material integrates the metal plate, the first conductive strip and the second conductive strip using an insert injecting scheme.

6. 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.

7. The mobile terminal of claim 6 , wherein the stub is positioned at a plane different from the first conductive strip or the second conductive strip.

8. The mobile terminal of claim 7 , wherein the case comprises 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.

9. The mobile terminal of claim 8 , 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.

10. The mobile terminal of claim 6 , wherein a first direction and a second direction are a horizontal direction of the case and wherein the stub is extended in a vertical direction along a side of the case.

11. The mobile terminal of claim 10 , 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 an end of the first coupling pattern and an end of the second coupling pattern are closely arranged in a manner of facing with each other.

12. The mobile terminal of claim 6 , wherein the stub is arranged in a manner of being separated from the metal plate and wherein the first antenna and the second antenna are extended in accordance with a length of the stub.

13. The mobile terminal of claim 6 , wherein the first feeder is extended according to the first conductive strip.

14. 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, wherein the switch is configured to change a flow of an electric current flowing through the first antenna.

15. 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.
