UHF RECTENNA USING A BOWTIE ANTENNA

By G. Monti and F. Congedo

Full Article PDF (622 KB)

Abstract:
In this paper, a rectifying antenna (rectenna) for energy scavenging applications is presented. The proposed device uses a modified bowtie antenna to collect the electromagnetic energy coming from UHF RFID systems, and RF Schottky diodes to convert it into DC power. Experimental results at 866 MHz demonstrating an RF-to-DC conversion efficiency of about 65% with an input power density of 60 μW/cm2 will be presented and discussed.
