This project presents a radio frequency harvesting system designed to cover GSM 1.8 GHz (1.6-2.1GHz), and WLAN 2.5 GHz (2.2 –2 .8 GHz). The system consists of two-part: A wideband circularly polarized monopole antenna with IBW of (1.55-2.47 GHz) and AR-BW of (1.80-2.62 GHz) and a rectifier circuit to convert the collected RF signal to DC power with a wideband range of frequency starting from 1.5 GHz to 2.7 GHz with minimum output voltage of 0.14 V at input power -10 dBm, and the maximum output voltage of 7.14 V at input power 20dbm, and the maximum efficiency is 67.1%,. the proposed rectenna shows the following measured results: At frequency 1.8 GHz at 0dbm the DC output volage equal 180 mV, at 20dbm the DC output volage equal 1.73V. At frequency 2.1 GHz at 0dbm the DC output volage equal 150 mV, at 20dbm the DC output volage equal 1.6 V. At frequency 2.4 GHz at 0dbm the DC output volage equal 0.13 V, at 20dbm the DC output volage equal 2.1 V.
