As shown in FIG. 3, when the second body 60 is slid up, the connecting terminal 90 and the second contact terminal 92b are brought into contact with each other, and thus the DMB receiving module 78 and the second body are in contact with each other. DMB antennas 70 embedded in 60 are in a state of being electrically connected to each other.

As shown in FIG. 4, when the second body 60 is swinged in the horizontal direction, the connection terminal 90 and the third contact terminal 92c are brought into contact with each other. The DMB antennas 70 embedded in the two bodies 60 are electrically connected to each other.

The portable terminal according to the present invention constructed and operated as described above has an advantage that the design of the terminal can be beautiful because there is no protruding portion of the terminal body because the antenna for the DMB is embedded in the second body.

In addition, there is no need to draw the DMB antenna to the outside of the terminal body, there is an advantage that it is convenient to use when implementing the terrestrial DMB.

 In addition, since the DMB antenna is built in the upper rear side of the second body, interference with other components mounted on the terminal body can be avoided, and there is no change in reception rate according to the slideless / down position of the first body, thereby improving antenna reception performance. There is an advantage that can be improved.

In addition, by embedding the DMB antenna on the upper rear of the second body, there is an advantage that the terminal can be miniaturized because the antenna mounting portion for removably mounting the DMB antenna to the first body is unnecessary.
