Abstract
Disclosed are an impedance matching method, an impedance matching apparatus for the same, and a record medium. The impedance matching apparatus includes an impedance matching part connected to an antenna to transmit/receive a radio wave and including at least one variable capacitor, a detector to detect transmit power and reflected power reflected by the antenna, and a controller to set a first searching region within a whole variation range of the variable capacitor, to detect an optimal impedance matching point within the first searching region by using at least one of the transmit power and the reflected power, and to set a next searching region about the optimal impedance matching point to search for a final impedance matching point within the whole variation range of the variable capacitor.
