ABSTRACT:
An antenna device for a portable terminal, which allows a whip antenna and helical antenna of a terminal to be retracted and withdrawn along an extension from the terminal, while not causing them to protrude out of the terminal. The antenna device provided with a whip antenna and helical antenna further includes an antenna housing disposed at a desired position in the main body, which permits the whip antenna to be retracted and withdrawn through the helical antenna, while causing the helical antenna to be withdrawn along an extension from the main body at the same time, and permits the helical antenna to be retracted, so that it can be inserted into the main body; and a housing coupling portion disposed in the main body for supporting the antenna housing.
