Abstract

A mobile terminal includes a window including a transparent region and an opaque region surrounding the transparent region, a metal case provided below the window to accommodate the window, having a rear surface portion facing the window and a side surface portion formed to extend from the rear surface portion toward a front surface, and exposed outwardly, a non-metal member formed in a region formed by cut away a portion of the case and having a slot formation portion spaced apart from the side surface portion at a predetermined interval and a pair of sectioning portions extending from the slot formation portion and traversing the side surface portion to section the side surface portion into first to third members, and first to third antenna patterns formed in the opaque region and electrically connected to the first to third members to form first and third antennas, respectively.

First claim

What is claimed is:

1. A mobile terminal comprising:
a window including:
a transparent region; and
an opaque region surrounding the transparent region;
a metal case provided below the window to accommodate the window, the metal case comprising:
a rear surface portion facing the window;
a side surface portion formed to extend from the rear surface portion toward a front surface, and exposed outwardly;
a non-metal member provided in a cut away portion of the case, the non-metal member having:
a slot formation portion forming a slot extending from the side surface portion or spaced apart from the side surface portion at a predetermined interval;
a pair of sectioning portions extending from the slot formation portion and traversing the side surface portion to section the side surface portion into first, second and third members to radiate electromagnetic waves independently; and
first, second and third antenna patterns formed in the opaque region and electrically connected to the first, second and third members, respectively, to form first, second and third antennas,
wherein the first, second and third antenna patterns are disposed on a lower surface of the window and have different antenna modes.

2. The mobile terminal of claim 1 , wherein the slot formation portion is disposed to be adjacent to an upper end portion of the mobile terminal.

3. The mobile terminal of claim 2 , wherein a through hole is provided in an upper portion of the case,
wherein a Near Field Communication (NFC) antenna is provided within the through hole, and
wherein first and second horizontal slot formation portions are formed at both end portions of the slot formation portion in a width direction of the mobile terminal to face the through hole.

4. The mobile terminal of claim 1 , wherein the first antenna is formed on a first side of an upper end of the case,
wherein the third antenna is formed on a second side, opposite to that of the first side, of the upper end of the case,
wherein the second antenna is formed between the first antenna and the third antenna, and
wherein the second antenna is a loop antenna.

5. The mobile terminal of claim 4 , wherein the first antenna and the third antenna are either a slot antenna or a planar inverter F-type antenna (PIFA).

6. The mobile terminal of claim 5 , wherein the first antenna is a PIFA and includes a first feeding part and a first grounding part connected to a main circuit board provided between the metal case and the window.

7. The mobile terminal of claim 6 , wherein the first grounding part is located at a point where the first member and the main circuit board are connected.

8. The mobile terminal of claim 6 , wherein the second antenna includes a second feeding part and a second grounding part connected to the main circuit board.

9. The mobile terminal of claim 8 , wherein the third antenna is a slot antenna and includes a third feeding part connected to the main circuit board, and
wherein the third antenna is spaced apart from a ground member at a predetermined interval to form a slot.

10. The mobile terminal of claim 4 , wherein a matching module for impedance matching of the first, second and third antennas is electrically connected to a main circuit board and is provided in at least one of the first, second and third members.

11. The mobile terminal of claim 4 , wherein the first, second and third antenna patterns are in contact with the first, second and third members by a contact in at least one point, respectively.

12. The mobile terminal of claim 1 , further comprising:
a wireless communication unit operably coupled to the first and second antennas and operable to permit communications between the mobile terminal and a wireless communication system, communications between the mobile terminal and another mobile terminal, and communications between the mobile terminal and an external server.

13. The mobile terminal of claim 12 , wherein the first and second antennas comprise a first member and a second member formed on the side surface portion, and
wherein at least one of the first and second antennas include an antenna pattern formed in the opaque region and electrically connected to the at least one of the first and second antennas.
