Abstract
Disclosed herein is an antenna device for use with a portable wireless terminal having a main body, and a sub-body slidably coupled to the main body. The antenna device includes a first antenna mounted in the main body, and a second antenna mounted on the sub-body. The second antenna is selectively exposed to the outside as the sub-body moves on the main body in a sliding manner. In case of a conventional sliding-type terminal, there is a problem in that an antenna device incorporated in its main body is interfered with by body parts of a user, thereby causing deterioration in the performance thereof. However, the antenna device according to the present invention compensates for such a deterioration in performance by using the additional second antenna mounted on the sub-body of the terminal. This improves the transmitting/receiving signal quality of the terminal. Furthermore, as such an antenna device is incorporated inside a sliding-type terminal or a pop-up type terminal, it is possible to eliminate a risk of damage and to diversify the design of the terminal.
