Broadband and Efficient Full Wave Rectenna for Wireless Energy

Abstract

This paper presents a novel approach to realize a broadband full wave rectenna for wireless energy transfer at 2.45 GHz ISM band. The full wave rectenna structure is designed using a center shorted dual edge feed microstrip patch antenna and two Schottky diodes. This antenna is inherently broadband in nature and can provide differential voltage at its two feed points. An optimized full wave rectenna is fabricated and tested. The proposed rectenna provides more conversion efficiency than a rectenna with similar antenna and conventional half wave rectifier.
