  • Combined DMB and mobile communication antenna apparatus for mobile communication terminal
    Patent number: 7425923
    Abstract: Disclosed is a combined DMB and mobile communication antenna apparatus for a mobile communication terminal. The antenna apparatus includes one whip antenna for receiving both signals in a DMB frequency band and in a mobile communication frequency band, a first contact coupled to the whip antenna to receive the signal in the mobile communication frequency band from the whip antenna, and a second contact located under the first contact within a terminal main body and coming in contact with the whip antenna at a lower end of the whip antenna to receive the signal in the DMB frequency band when the whip antenna is drawn out.
