In this paper, an experimental RF (Radio Frequency) energy harvesting system using rectifying antenna (rectenna) to harvest ambient energy from cell phones operating at 900MHz GSM band is presented. The proposed circuit is a combination of RMPA (Rectangular Micro strip Patch Antenna) and rectifying circuit using Schottky diode for microwave RF to DC conversion. The performance of the rectenna is simulated by electromagnetic simulator Computer Simulation Technology (CST) Microwave Studio. Rectenna offers maximum radiation efficiency of around 55.61%, gain of 3.4dBi and directivity of 5.972dBi.
