Abstract
The present invention relates to an apparatus for impedance matching in a dual standby portable terminal, and a method thereof. The apparatus for impedance matching is configured with first and second modules. The second module includes an antenna for radiating a radio frequency signal, a radio communication unit having a sending end for outputting a radio frequency signal and a receiving end for receiving a radio frequency signal, an impedance matching circuit unit having a specific impedance value, a switch unit for connecting one of the sending end, the receiving end, and the impedance matching circuit unit, to the antenna and a control unit for controlling the switch unit to selectively connect one of the sending end, the receiving end, and the impedance matching circuit unit, to the antenna.
