  • Antenna apparatus for folder type mobile phone
    Patent number: 6897825
    Abstract: An antenna apparatus for a folder type mobile phone, wherein a first antenna is installed in a main body of the folder type mobile phone, and a second antenna is installed in the folder. The folder type mobile phone installs a main antenna apparatus in the main body, and an antenna apparatus for maximizing the diversity effect in the folder. As a result, it becomes more convenient to carry the folder type mobile phone based on the diversity mode, while securing a broader separation distance between two antennas at the same time.

  • Dual antenna capable of controlling radiation characteristics in a mobile communication terminal
    Patent number: 6707431
    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.
