This research presents a small rectifier that can gather ambient radio frequency (RF) power. Controlling the resonant frequency of the antenna allows the designer to target the available sources of electromagnetic energy, such as Wi-Fi, WLAN, and Wi-MAX, altering current (AC) by the antennas and converting it into direct current (DC) by the receiver. The receiver is designed on an FR-4 substrate using a single-stage voltage multiplier at 2.4, 3.6, and 5 GHz. This is one of the beneficial energy sources for RF Energy Harvesting (RFEH) that has a large range, little path loss, and high input power. The proposed RFEH rectifier at 2.4 GHz achieves a simulated RF-to-DC (RF to direct current) power conversion efficiency (PCE) of 45.22% for 10 dBm input power. Additionally, the rectifier attained a 2.2 V DC output voltage across the 3 kΩ load terminal. The input power level is changed from -10 to 25 dBm. ADS software (Advanced Design System) is used to simulate the proposed structures.
