Abstract
An impedance matching apparatus is provided. The impedance matching apparatus includes a signal separation unit, an impedance detection unit, and an impedance matching unit. The signal separation unit separates a transmission and reception signal, and selectively passes a desired frequency corresponding to the transmission and reception signal. The impedance detection unit receives a signal outputted from the signal separation unit to detect first and second electric potentials between a plurality of impedances. The impedance matching unit compares the first and second electric potentials detected by the impedance detection unit to match the impedances.
