Provided is a wireless communication device for receiving a mobile broadcasting signal and transmitting/receiving a Bluetooth® signal through a single antenna, which allows separation of the two signals using a difference in their frequency bands. A diplexer separates the signals using different band-pass filters. The signals are respectively input into a mobile broadcasting module and a Bluetooth® module. The wireless communication device allows reception of mobile broadcasting and Bluetooth signals within different frequency bands through a single antenna, thus achieving a compact and thin device with a reduced antenna mounting space.
