ABSTRACT:
An antenna includes a keypad assembly having a plurality of key buttons, a main antenna unit, and a second antenna unit where a predetermined pattern is formed. The second antenna unit is interposed between components of the keypad assembly. Accordingly, a separate installation space for the antenna radiator is not required in the main board, thus contributing to volume reduction of the terminal. Also, since an installation area corresponding to the total area of the keypad assembly is available, antennas for different bands may be installed.
