    • A patch antenna for receiving high frequency wireless signal and a rectenna using the same, more particularly, an impedance-matched patch antenna adopting a slot capacitive coupling structure and a rectenna capable of generating electrical energy from the wireless signals having different frequency band. A rectenna for receiving an A.C. wireless signal carrying electrical energy and converting the wireless signal into a D.C. electrical energy, is comprised of: a patch antenna for receiving the wireless signal comprising an dielectric substrate, a patch that is formed at the upper area of the surface of the dielectric substrate and providing the first frequency response characteristics, a ground plane formed on the other surface of the dielectric substrate, and an impedance matching means providing the second frequency response characteristics; and a rectifying unit that converts the wireless signal, received via the patch antenna, into a D.C. electrical energy by rectifying the wireless signal.
