Abstract

In this paper, an antenna has been proposed for the operation of mobile devices such as Zigbee. The presented rectenna operates at ISM (Industrial Scientific Medical) band of 2.45 GHz and consists of $2{\times}2$ array patch antenna and Villard voltage double rectifier circuit for high conversion efficiency. $2{\times}2$ array patch antenna is fabricated in FR4 substrate having thickness of 1.6mm and dielectric constant of 4.7. The proposed $2{\times}2$ array patch antenna resonates at 2.56GHz with return loss of 38.36dB, VSWR of 1.0244, and its impedance is matched to $50{\Omega}$. The fabricated rectenna has maximum conversion efficiency of 59.8% at an input power lever of 15dBm and load resistance of $500{\Omega}$.
