Abstract

A portable device with a sliding variable built-in antenna is provided including a main body, a variable built-in antenna which is assembled at a predetermined location of the main body and configured to slide up/down with respect to the main body according to an antenna reception sensitivity, and an electrical connection device for signal transmission between the main body and the variable built-in antenna.

Claims

1. A portable device comprising:

a main body;

a variable built-in antenna which is assembled at a predetermined location of the main body and configured to slide up/down in a longitudinal direction of the main body according to antenna reception sensitivity, the variable built-in antenna comprising a slidable antenna housing to receive and cover at least four indented sides of an edge of the main body when retracted; and

an electrical connection device for signal transmission between the main body and the variable built-in antenna.

2. The portable device of claim 1, wherein the antenna housing comprises:

an edge portion, first and second side portions, and a rear portion to cover a predetermined portion of the main body, wherein

the first and second side portions facilitate an opening/closing of the antenna housing, such that the antenna housing slides in a longitudinal direction of the main body while facing the main body, and wherein,

the opening/closing of the antenna housing is based upon an antenna reception sensitivity.

3. The portable device of claim 1, wherein the variable built-in antenna is assembled with a top portion or a bottom portion of the main body.

4. The portable device of claim 1, wherein the main body comprises:

a front surface;

a sliding housing mounted on the front surface of the main body, wherein the sliding housing is configured to linearly slide in the longitudinal direction of the main body while facing the main body;

at least one of a speaker unit, a display unit neighboring the speaker unit, and a first keypad which neighbors the display unit and which comprises a plurality of keys, mounted on a front surface of the sliding housing; and

at least one of a second keypad which comprises a plurality of keys being exposed when the sliding housing is slid upward, and a microphone unit neighboring the second keypad, mounted on the front surface of the main body.

5. The portable device of claim 1, wherein the variable built-in antenna is configured to slide up/down in any one of an automatic, manual and semiautomatic operation modes.

6. A portable device comprising:

a main body;

a folder which is rotatably opened/closed with respect to the main body on a hinge axis;

a variable built-in antenna which is assembled to face a bottom portion of the main body and configured to slide up/down in a longitudinal direction of the main body according to an antenna reception sensitivity, the variable built-in antenna comprising a slidable antenna housing to receive and cover at least four indented sides of an edge of the main body when retracted; and

an electrical connection device for signal transmission between the main body and the variable built-in antenna.

7. A portable device comprising:

a main body;

a folder which is rotatably opened/closed with respect to the main body on a hinge axis;

a variable built-in antenna which is assembled to face a top portion of the folder and configured to slide up/down in a longitudinal direction of the folder according to an antenna reception sensitivity, the variable built-in antenna comprising a slidable antenna housing to receive and cover at least four indented sides of an edge of the main body when retracted; and

an electrical connection device for signal transmission between the folder and the variable built-in antenna.

8. A portable device comprising:

a main body;

a swing housing which is rotatably opened/closed on a hinge axis while facing a front surface of the main body;

a variable built-in antenna which is assembled to face a bottom portion of the swing housing and configured to slide up/down in a longitudinal direction of the swing housing according to an antenna reception sensitivity, the variable built-in antenna comprising a slidable antenna housing to receive and cover at least four indented sides of an edge of the main body when retracted; and

an electrical connection device for signal transmission between the swing housing and the variable built-in antenna.

9. A portable device comprising:

a main body;

a swing housing which is rotatably opened/closed on a hinge axis while facing a front surface of the main body;

a variable built-in antenna which is assembled to face a top portion of the swing housing and configured to slide up/down in a longitudinal direction of the swing housing according to an antenna reception sensitivity, the variable built-in antenna comprising a slidable antenna housing to receive and cover at least four indented sides of an edge of the main body when retracted; and

an electrical connection device for signal transmission between the swing housing and the variable built-in antenna.

10. A portable device comprising:

a main body;

a sliding housing which is assembled around a predetermined portion of the main body and configured to slide up/down in a longitudinal direction of the main body and receive and cover at least four indented sides of an edge of the main body when retracted;

a variable built-in antenna which is assembled to face a top portion of the sliding housing and configured to slide up/down in a longitudinal direction of the sliding housing according to an antenna reception sensitivity; and

an electrical connection device for signal transmission between the sliding housing and the variable built-in antenna.

11. A portable device comprising:

a main body;

a sliding housing which is assembled around a predetermined portion of the main body and configured to slide up/down in a longitudinal direction of the main body and receive and cover at least four indented sides of an edge of the main body when retracted;

a variable built-in antenna which is assembled to face a bottom portion of the sliding housing and configured to slide up/down in a longitudinal direction of the sliding housing according to an antenna reception sensitivity; and

an electrical connection device for signal transmission between the sliding housing and the variable built-in antenna.
