Abstract In this paper an experimental RF energy harvester using rectifying antenna (rectenna) to harvest ambient energy from cellular device operating at 900 MHz GSM band is proposed. The circuit is a combination of antenna and rectifying circuit using Schottky barrier diode for microwave (RF) to DC conversion. The performance results of the rectenna shows radiation efficiency of around 58.81%, gain of 3.9 dB and directivity of 5.972 dBi. The proposed rectenna design can prove to be a low cost device for wireless power transmission and RF energy harvesting. The prototype is fabricated with simulated and measured results in good agreement, having a return loss of 21 dB at frequency of around 885 MHz. The overall efficiency is enhanced by using ISS351-TB-E Schottky diode which is categorized by a low junction capacitance and a low threshold voltage to achieve higher conversion efficiency.

This work presents, a printed wideband microstrip antenna that can be used for portable RF energy harvesting applications. The antenna is designed, simulated and validated using 3D electromagnetic HFSS simulator. The targeted frequency band of operations are from 0.825 GHz to 1.05 GHz for catering GSM/3G wireless applications. Following the antenna design in the HFSS software, the structure has been fabricated on low cost substrate FR4 and the structure performance is analyzed experimentally. The achieved wideband, omni directional patterns with constant gain monopole antenna can be suitable for all portable system applications.
