Apparatus for impedance matching in dual standby portable terminal and method thereof

A method of impedance matching in a dual standby portable terminal, the method comprising:

• executing radio communication using a first module of the portable terminal;
• determining a function associated with a slot time of a second module of the portable terminal;
• and
• connecting at least one of a sending end, a receiving end and an impedance matching circuit unit of the second module to an antenna of the second module according to the determined function associated with the slot time.

An apparatus for impedance matching in a dual standby portable terminal, the apparatus comprising:

• a first module;
• and
• a second module,
• wherein the second module comprises:
• an antenna;
• an impedance matching circuit unit comprising a specific impedance value;
• a switch unit;
• and
• a control unit for controlling the switch unit to selectively connect one of the impedance matching circuit unit and a signal path of the second module to the antenna in accordance with whether the second module is executing a scheduled communication.
