Abstract

Disclosed are an antenna module and a mobile terminal having the same. The antenna module includes a ground plate; a metal plate spaced apart from the ground plate by a distance such that a surface of the metal plate faces a surface of the ground plate; a first conductive member spaced apart from an edge of the ground plate by a distance, the first conductive member encompassing the edge; a feeding part formed on the ground plate; a second conductive member formed on the ground plate and coupled to the feeding part, wherein the second conductive member indirectly feeds the first conductive member and the metal plate; and a first connection member and a second connection member that couple the ground plate to the metal plate.

First claim

What is claimed is:

1 . An antenna module, comprising:
a ground plate; a metal plate spaced apart from the ground plate by a distance such that a surface of the metal plate faces a surface of the ground plate; a first conductive member spaced apart from an edge of the ground plate by a distance, the first conductive member encompassing the edge; a feeding part formed on the ground plate; a second conductive member formed on the ground plate and coupled to the feeding part, wherein the second conductive member indirectly feeds the first conductive member and the metal plate; and a first connection member and a second connection member that couple the ground plate to the metal plate.

2 . The antenna module of claim 1 , wherein positions, at which the first connection member and the second connection member are formed, are variable between an end portion of the first conductive member and an intermediate portion of the first conductive member.

3 . The antenna module of claim 2 , further comprising:
a third conductive member formed on the metal plate and spaced apart from the second conductive member by a distance, and the third conductive member is indirectly fed by the second conductive member.

4 . The antenna module of claim 3 , wherein the second conductive member and the third conductive member are coupled by a third connection member.

5 . The antenna module of claim 1 , further comprising a fourth conductive member and a fifth conductive member, each having a first end connected to the feeding part and a second end connected to the metal plate.

6 . The antenna module of claim 1 , further comprising a first switch and a second switch that are configured to selectively operate a fourth connection member and a fifth connection member to connect the first conductive member to the metal plate.

7 . The antenna module of claim 6 , wherein the fourth connection member and the fifth connection member are provided at an inner side of a region where the first connection member and the second connection member are connected with the first conductive member.

8 . The antenna module of claim 1 , wherein the first conductive member has a “C” shape.

9 . The antenna module of claim 1 , wherein the ground plate is a printed circuit board.

10 . The antenna module of claim 9 , wherein the first conductive member is formed on an extension part of the printed circuit board.

11 . The antenna module of claim 1 , wherein the first conductive member is formed on a carrier having a dielectric constant, or formed at an outside of an insulation part formed on an edge of the ground plate.

12 . The antenna module of claim 1 , wherein the first conductive member is one of a conductive line, a pogo pin, a c-clip, or an electromagnetic interference (EMI).

13 . A mobile terminal, comprising:
a terminal body; and an antenna module provided within the terminal body and comprising:
a ground plate;
a metal plate spaced apart from the ground plate by a distance such that a surface of the metal plate faces a surface of the ground plate;
a first conductive member spaced apart from an edge of the ground plate by a distance, the first conductive member encompassing the edge;
a feeding part provided on the ground plate;
a second conductive member formed on the ground plate and coupled to the feeding part, wherein the second conductive member indirectly feeds the first conductive member and the metal plate; and
a first connection member and a second connection member that couple the ground plate to the metal plate.

14 . The mobile terminal of claim 13 , wherein the metal plate is a rear cover covering the terminal body.

15 . The mobile terminal of claim 13 , further comprising:
a third conductive member formed on the metal plate and spaced apart from the second conductive member by a distance, wherein the third conductive member is indirectly fed by the second conductive member.

16 . The mobile terminal of claim 15 , further comprising:
a fourth conductive member and a fifth conductive member, each having a first end connected to the feeding part and a second end connected to the metal plate, wherein the fourth conductive member and the fifth conductive member are formed at an inner side of a side surface of the terminal body.

17 . The mobile terminal of claim 13 , further comprising a first switch and a second switch that are configured to selectively operate a fourth connection member and a fifth connection member to connect the first conductive member to the metal plate.

18 . The mobile terminal of claim 13 , wherein the ground plate is a printed circuit board or an intermediate frame provided within the terminal body.
