Abstract
An apparatus and method for matching impedance of an antenna by using Standing Wave Ratio (SWR) information is provided. While the impedance of the impedance matching unit is controlled, a region of a Smith chart in which initial total impedance of the impedance matching unit and the antenna is located by using an SWR calculated by an SWR operation unit, and the impedance of the impedance matching unit is controlled according to the determined region, thus correctly matching the impedance of the antenna.
