Abstract

In this paper, an experimental RF energy harvesting system using rectifying antenna (rectenna) to harvest ambient energy from Wi-Fi at 2.45 GHz is presented. The proposed circuit is a combination of RMPA, followed by a third order stepped impedance low-pass filter, matching network and rectifier 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 198 mV of output DC voltage at a distance of about 15 cm from the router. Slots are added to proposed rectenna thereby making it a multiband rectenna thereby operating in ISM band.
