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/cm 2 will be presented and discussed.
