Abstract

There is disclosed a mobile terminal comprising a rear case made of metal and forming an exterior of a rear surface of the mobile terminal, the rear case comprising a first slit; a reinforcing member made of a non-conductive material, coupled to a first region of the rear having the first slit, wherein the reinforcing member protrude inward of the rear case and form an uneven portion; a first conductive pattern coupled to an inner surface of the rear case and forming a cut-off region in the first region, the first conductive pattern formed in a ring shape; and a second conductive pattern provided in a corresponding shape to uneven portion of the reinforcing member and electrically connecting the cut-off region of the first conductive pattern.

First claim

What is claimed is:

1. A mobile terminal comprising:
a case defining at least a portion of an exterior of the mobile terminal;
a slit provided in a region of the case;
a reinforcing member coupled to an inner surface of the region of the case, the reinforcing member filling in the slit, the reinforcing member being made of a non-conductive material, the reinforcing member protruding inward of the case and having an uneven portion at an inner surface of the reinforcing member;
a first conductive pattern coupled to an inner surface of the case and having two separated ends that define a cut-off region at the region of the case, the first conductive pattern having a ring shape; and
a second conductive pattern electrically connecting the two separated ends of the first conductive pattern that define the cut-off region, the second conductive pattern having a shape that corresponds to a shape of the uneven portion of the reinforcing member.

2. The mobile terminal of claim 1 , wherein the second conductive pattern is injection-molded and fixed to the first conductive pattern by Surface Mount Technology (SMT).

3. The mobile terminal of claim 2 , wherein the second conductive pattern comprises phosphor bronze or stainless steel.

4. The mobile terminal of claim 1 , wherein the second conductive pattern is longer than a distance between the two separated ends of the first conductive pattern that define the cut-off region.

5. The mobile terminal of claim 1 , further comprising:
a first flexible printed circuit board (FPCB) having the first conductive pattern located thereon and coupled to the inner surface of the case; and
an electromagnetic wave shield configured to cover the first FPCB.

6. The mobile terminal of claim 5 , wherein the electromagnetic wave shield is a ferrite sheet.

7. The mobile terminal of claim 5 , further comprising a second FPCB having the second conductive pattern located thereon.

8. The mobile terminal of claim 1 , further comprising a gold plating portion coated on the second conductive pattern.

9. The mobile terminal of claim 1 , further comprising an insulator configured to cover the second conductive pattern.

10. The mobile terminal of claim 1 , wherein an outer surface of the reinforcing member and an outer surface of the case are coplanar.

11. The mobile terminal of claim 1 , wherein the case is a rear case made of metal.

12. The mobile terminal of claim 11 , further comprising a rear camera,
wherein the rear case includes an opening configured to expose the rear camera, and
wherein the first conductive pattern is located around the opening.

13. The mobile terminal of claim 1 , wherein the first conductive pattern is an inductance wound several times, and
wherein the second conductive pattern includes a plurality of lines connected to the first conductive pattern.

14. The mobile terminal of claim 1 , wherein the first conductive pattern and the second conductive pattern provide a Near Field Communication (NFC) antenna.

15. The mobile terminal of claim 1 , further comprising a protection layer on an outermost surface of the case, the protection layer being a transparent film.

16. The mobile terminal of claim 1 , further comprising a coating layer on an outermost surface of the case, the coating layer including an anodized metallic material.

17. A mobile terminal comprising:
a front case;
a display located at the front case;
a rear case defining an exterior of a rear surface of the mobile terminal;
a slit provided in a region of the rear case;
a reinforcing member coupled to an inner surface of the region of the rear case, the reinforcing member filling in the slit, the reinforcing member being made of a non-conductive material, the reinforcing member having a first portion located in the slit and a second portion protruding inward of the rear case, the second portion having an uneven portion at an inner surface of the reinforcing member;
a first conductive pattern coupled to an inner surface of the rear case and having two separated ends that define a cut-off region at the region of the rear case, the first conductive pattern having a ring shape; and
a second conductive pattern electrically connecting the two separated ends of the first conductive pattern that define the cut-off region, the second conductive pattern having a shape that corresponds to a shape of the uneven portion of the reinforcing member.

18. The mobile terminal of claim 17 , wherein the rear case is made of metal.

19. The mobile terminal of claim 17 , wherein the first conductive pattern and the second conductive pattern provide a Near Field Communication (NFC) antenna.

20. The mobile terminal of claim 17 , further comprising a rear camera,
wherein the rear case includes an opening configured to expose the rear camera, and
wherein the first conductive pattern is located around the opening.
