PURPOSE: A power coupler is provided to increase output power. CONSTITUTION: A power coupler(100) includes a base board(110), a conductive line pattern(120), a capacitor(130), and a wire structure(140). The base board supports the components of the power coupler. The conductive line pattern is included in power coupling by being coupled electrically. The capacitor(130) includes an input capacitor(132) and an output capacitor(134). The wire structure is equipped on the conductive line pattern and is included in the power coupling by being coupled with the conductive line pattern electrically.
