Abstract

Disclosed herein is a mobile terminal including a terminal body comprising a circuit board formed to process radio signals, a first and a second member configured to form an external appearance of the terminal and disposed to cover a lateral surface of the circuit board, a power feed connecting portion to allow the first member and the circuit board to be power feed connected, and a ground connecting portion to allow the first member and the circuit board to be ground connected. Accordingly, an electrical element and an antenna are disposed adjacent to each other, allowing the effective use of a space within the terminal.

First claim

What is claimed is:

1. A mobile terminal comprising:
a circuit board;
at least one antenna pattern disposed inside of a case that forms an exterior of the mobile terminal such that no portion of the at least one antenna pattern is exposed externally, wherein the at least one antenna pattern is operable as a radiator;
a metal cover constructed as part of the case, the metal cover divided into a first member and a second member separated from the first member such that the first member does not contact the second member, wherein the first member is electrically connected to a part of the at least one antenna pattern without a contact structure between the first member and the part of the at least one antenna pattern, and wherein the first member and the second member are separated from each other by a first slit portion formed at a first end portion of the first member and a second slit portion formed at a second end portion of the first member;
a power feed connector for facilitating an electric power feed connection between the first member and the circuit board; and
a ground connector for facilitating an electric ground connection between the first member and the circuit board,
wherein the at least one antenna pattern is separated from the first member by a gap having a predetermined distance for coupling with the first member, and
wherein the first slit portion and the second slit portion are configured to block a current flow from the first member to the second member.

2. The mobile terminal of claim 1 , further comprising a speaker module, an interface module or a microphone module located in an area defined by the circuit board, the first member, and the second member.

3. The mobile terminal of claim 1 , wherein the at least one antenna pattern comprises:
a first pattern extending from the power feed connector and forming a conductive loop, the first pattern separated from the first member by a gap having a predetermined distance for facilitating a coupling for power feeding.

8. The mobile terminal of claim 1 , wherein:
the power feed connector, the first member and the ground connector form a conductive loop; and
the conductive loop has one or more paths that connect the power feed connector to the ground connector via the first member and that have a length of a half wavelength corresponding to a specific frequency.

9. A mobile terminal comprising:
a circuit board;
at least one antenna pattern disposed inside of a case that forms an exterior of the mobile terminal such that no portion of the at least one antenna pattern is exposed externally, wherein the at least one antenna pattern is operable as a radiator;
a metal cover constructed as part of the case forming an exterior of the mobile terminal, the metal cover divided into a conductive member and a bezel member separated from the conductive member such that the conductive member does not contact the bezel member, wherein the conductive member is electrically connected to a part of the at least one antenna pattern without a contact structure between the conductive member and the part of the at least one antenna pattern;
a power feed connector coupled with the conductive member;
a ground connector coupled with the conductive member and an embedded ground such that the ground connector, the conductive member and the power feed connector form a conductive loop, and
either a through portion that is located at an end of the mobile terminal and passes through at least a portion of the conductive member in order to adjoin an interior and the exterior of the mobile terminal or a slit portion separating the conductive member into a plurality of members,
wherein the at least one antenna pattern is separated from the conductive member by a gap having a predetermined distance for coupling with the conductive member, and
wherein the through portion or the slot portion is configured to block a current flow from the conductive member to the bezel member.

10. The mobile terminal of claim 9 , wherein the conductive loop has one or more paths connecting the power feed connector to the ground connector via the conductive member.

11. The mobile terminal of claim 10 , wherein the one or more paths have a length of a half wavelength corresponding to a specific frequency.

12. The mobile terminal of claim 9 , further comprising a speaker module, an interface module or a microphone module located adjacent to the conductive member.
