Disclosed herein is an antenna device for a mobile phone having a body housing, a sliding housing for sliding up or down lengthwise along the body housing, a sliding module for connecting the sliding housing to the body housing in the manner that allows the sliding housing to slide up or down, and a main antenna device in the sliding housing. In the antenna device for the mobile phone, at least one sub-antenna device is installed lengthwise facing the sliding module and is electrically connected to or separated from the body housing, slidingly approaching or moving away from the body housing along with the sliding module, and at least one connection unit electrically connects the sub-antenna device to the body housing for signal transmission between the sub-antenna device and the body housing.

What is claimed is: 1. An antenna device in a mobile phone having a body housing, a sliding housing for sliding up or down in a lengthwise direction along the body housing, a sliding module for connecting the sliding housing to the body housing to allow the sliding housing to slide up or down, and
What is claimed is: 1. An antenna device in a mobile phone having a body housing, a sliding housing for sliding up or down in a lengthwise direction along the body housing, a sliding module for connecting the sliding housing to the body housing to allow the sliding housing to slide up or down, and a main antenna device installed on a first plane in the sliding housing, the antenna device comprising: at least one sub-antenna device installed in the lengthwise direction facing the sliding module and on a second plane perpendicular to the first plane, for electrically connecting to or separating from the body housing, slidingly approaching or moving away from the body housing along with the sliding module; and at least one connection unit for electrically connecting the at least one sub-antenna device to a main printed circuit board (PCB) installed on a third plane parallel to the first plane and in the body housing for signal transmission between the at least one sub-antenna device and the main PCB. 2. The antenna device of claim 1, wherein two sub-antenna devices are symmetrically installed with respect to the body housing in the vicinity of the inner side surfaces of the sliding module. 3. The antenna device of claim 1, wherein the at least one sub-antenna device is formed in a meander line pattern. 4. The antenna device of claim 1, wherein the at least one connection unit includes a connection terminal provided at one end of the at least one sub-antenna device, and a connector is provided at an end of the body housing for electrically connecting to the connection terminal. 5. The antenna device of claim 4, wherein the connector is formed of metal. 6. The antenna device of claim 4, wherein the connector includes a screw engagement portion at an end of the connector, for securing the connector to the body housing, and a connection portion at an other end of the connector, for being electrically connected to the connection terminal. 7. The antenna device of claim 6, wherein the screw engagement portion includes a curved fixing portion for fixedly engaging with a fixing groove formed in the body housing. 8. The antenna device of claim 6, wherein the connection portion is a pin connector. 9. The antenna device of claim 8, further comprising a connector hole formed in the body housing, for allowing the pin connector to extend through the connector hole. 10. The antenna device of claim 4, further comprising two antenna engagement portions in the main PCB, for being electrically connected to the screw engagement portion, and a connection line between antenna engagement portions, for electrically connecting the two antenna engagement portions. 11. The antenna device of claim 1, wherein as the sliding module slides up the sliding housing in the lengthwise direction away from the body housing, a connector of the at least one sub-antenna device slides up along with the sliding module and is electrically connected to a connection portion of the connector, whereby increasing reception sensitivity is achieved by using both the at least one sub-antenna device and the main antenna device as an antenna, and wherein, as the sliding module slides down the sliding housing in the lengthwise direction toward the body housing, the connector of the at least one sub-antenna device slides down along with the sliding module and is electrically separated from the connection portion of the connector, and only the main antenna device is used as the antenna. 12. An antenna device in a sliding type mobile phone having a body housing, a sliding housing for sliding up or down in a lengthwise direction along the body housing, and a main antenna device installed on a first plane in the sliding housing, the antenna device comprising: at least one sub-antenna device installed in the lengthwise direction in the sliding housing and on a second plane perpendicular to the first plane, for electrically connecting to or separating from the body housing, slidingly approaching or moving away from the body housing along with the sliding housing; and at least one connection unit for electrically connecting the at least one sub-antenna device to a main printed circuit board (PCB) installed on a third plane parallel to the first plane and in the body housing for signal transmission between the sub-antenna device and the main PCB. 13. An antenna device in a mobile phone having a body housing, a sliding housing for sliding up or down in a lengthwise direction along the body housing, a sliding module for connecting the sliding housing to the body housing to allow the sliding housing to slide up or down, and a main antenna device installed on a first plane in the sliding housing, the antenna device comprising: at least one sub-antenna device installed in the lengthwise direction facing the sliding module and on a second plane perpendicular to the first plane, for electrically connecting to or separating from the body housing; and at least one connection unit for electrically connecting the at least one sub-antenna device to a main printed circuit board (PCB) installed on a third plane parallel to the first plane and in the body housing for signal transmission between the at least one sub-antenna device and the main PCB.
