Novel Rectenna Using Modified Ground Plane for RF Energy Harvesting

摘要

In this paper, a novel antenna using modified ground plane for RF energy harvesting was proposed. This antenna is composed of the main radiator and the modified ground plane. The main radiator designed as a dipole type covers WCDMA-band in Korea and the ground plane is used to harvest the RF energy from the main radiators, which don't disturb the main radiator's electrical performance. The ground plane has a rectangular structure with vertical metallic walls in order to suppress and harvest the back-lobe of the antenna. The amount of the harvested energy from this rectenna is approximately 1% of the originally radiated power. The simulated gain of the proposed antenna is almost same with that of the printed dipole without the metallic walls. And the back-lobe of the proposed rectenna was reduced to 7.0 dB.
