2.45-GHz 무선전력송신을 위한 렉테나 구현.

This paper presents the design and fabrication of a rectenna that receives 2.45 GHz RF signals and converts them into DC power. The rectenna comprises a patch antenna, matching network, and rectifier. It was manufactured and measured using a 0.76-mm thick RF-35A2 board. The matching network was implemented using transmission lines and open stubs and designed to stably convert the RF signal into a fixed DC voltage by employing parallel inductors. The measured rectenna achieved a maximum RF–DC conversion efficiency of 38 % at 2.3-dBm input power and a 1.5-kΩ load. When used in conjunction with the fabricated patch antenna, it transmitted 1.8 V of power at 36 mW into a 90-Ω load at a distance of 10 cm. [ABSTRACT FROM AUTHOR]
