PATCH ANTENNA AND RECTENNA USING THE SAME
First Claim
1. A patch antenna comprising:
- an dielectric substrate;
a patch that is formed on the first surface of the dielectric substrate and provides the first frequency characteristics; and
a ground plane that is formed on the second surface of the dielectric substrate,wherein an impedance matching means, that is capacitively coupled with the patch, is formed on the one side of the ground plane.

Abstract
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.
