Design, Simulation, and Performance Evaluation of a 2.4 GHz RF Energy Harvester

Abstract

 A radio frequency energy harvester is a device that can power low-power devices without using typical power sources by converting ambient radio frequency electromagnetic waves into usable electrical energy. A new 2.4 GHz frequency band RF energy harvester is suggested in this article. The circuit employs a voltage multiplier cum rectifier for rectification purposes, and a low forward volatge drop Schottky diode HSMS2860_20000301 is utilized for rectifier implementation. LC impedance matching is used to increase the RFEH circuit performance in terms of conversion efficiency and output voltage. The rectifier is simulated with the Advanced Design System (ADS). The Proposed rectifier circuits exhibits the performs optimally at load impedance of 500Ω. After simulation, results reveal a conversion efficiency of 71.88% and 1.896V of output voltage with 10 dBm RF input power at 2.4 GHz frequency band.
