Summary:A dual antenna capable of controlling a radiation characteristic in a folder type mobile communication terminal. The dual antenna comprises a first directional antenna mounted on a folder of the mobile communication terminal, and a second directional antenna mounted on a body of the mobile communication terminal. In a suspended state where the folder is folded against the body, the first and second directional antennas have directivities in an opposite direction. However, in a call state where the folder is unfolded away from the body, the first and second directional antennas have directivities in the same direction. Preferably, the first directional antenna is mounted on a rear side of the body of the mobile communication terminal, and the second directional antenna is mounted on an outer side of the folder of the mobile communication terminal.
