Provided is a video telephony apparatus and method for mobile terminals. The video telephony apparatus includes a controller, a display unit, a codec, and a content controller. The controller exchanges protocol signals for a video call with the other party terminal, and demultiplexes a moving image and a voice that are received from the other party terminal. The display unit displays the received moving image, and the codec plays the received voice. The content controller manages Right Objects (ROs) of multimedia contents received from the other party terminal, and captures the displayed moving image and the played voice according to the ROs. Accordingly, it is possible to protect portrait rights during the video call.

The present invention discloses an antenna for ultra-wideband (UWB) communication having a band-stop characteristic. According to an embodiment of the present invention, the UWB antenna is a patch antenna employing microstrip feeding. In order to expand a bandwidth at a low frequency band, a stub is formed in a radiating element. Furthermore, since steps are formed in a ground plane, an antenna characteristic at an intermediate frequency band can be improved and a UWB characteristic can be obtained. According to another embodiment of the present invention, the UWB antenna is a patch antenna employing microstrip feeding and has a recess formed in the ground plane, thereby implementing the UWB characteristic. The antenna of the present invention has an inverse U-shaped slot formed in the radiating element, thus implementing the band-stop characteristic at the UNII band. In addition, the antenna of the present invention has includes a ground plane having a small area and has omnidirectional radiating patterns accordingly.
