  • Publication number: 20080085734
    Abstract: A method and device for receiving a digital multimedia broadcasting (DMB) signal in a wireless terminal where an external antenna is detachable from the wireless terminal, an internal antenna is embedded in the wireless terminal, a switch connects one of the external antenna and the internal antenna to a DMB receiver. The DMB receiver receives a DMB signal through one of the external antenna and the internal antenna. A controller controls the switch to connect the internal antenna and transmit the DMB signal to the DMB receiver when the external antenna is detached from the wireless terminal and controls the switch to connect the external antenna to the DMB receiver and transmit the DMB signal to the DMB receiver, when the external antenna is attached to the wireless terminal.
