It is about a method.

Portable terminals have become common to the general public due to rapid spread, and accordingly, portable terminals having a complex concept with various functions added to satisfy consumer needs in addition to a simple call function have been developed. For example, an on-demand video viewing function, a video call function, a digital camera function, an internet function, a TV viewing function, etc., in addition to the existing voice call, refer to an added service required by the user.

Among the various additional services mentioned above, the portable terminal having a TV viewing function refers to a complex mobile communication terminal that can watch TV broadcast programs using a display device in addition to the mobile communication telephone function.

The portable terminal having a TV function includes at least two RF units because frequency bands required for transmission and reception of unique voice and data transmissions and TV broadcasts are different from each other. It has a standby mode and a TV mode that also serves as the standby mode and the image receiving mode. A typical TV broadcast signal antenna is connected to an internal tuner, and an antenna for transmitting and receiving voice signals is generally connected to a duplexer.

However, a portable terminal having a TV function needs to receive a TV broadcast signal as well as a signal for general voice transmission and reception, thereby providing two antenna apparatuses for receiving these signals and a structure of the apparatus according to the general voice call portable terminal.
