Abstract

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.

Description

technical field [0001] The present invention generally relates to an antenna for a mobile communication terminal such as a mobile phone, and in particular, to a dual antenna capable of controlling the emission characteristics of the mobile communication terminal. A mobile communication terminal, preferably a folding type (dual LCD (liquid crystal display) folding type) mobile communication terminal, has two directional antennas - one mounted on the folding portion and the other mounted on the main body of the mobile communication terminal, so that the emission characteristics The standby state in which the folded part is folded toward the main body and the talking state in which the folded part is unfolded from the main body are separately controlled, which contributes to the improvement of antenna performance and the reduction of electromagnetic waves radiated toward the user's head. Background technique [0002] Generally, a mobile communication term...
