WI-FI ENERGY HARVESTER WITH DIFFERENTIAL MATCHING ANALYSIS FOR LOW-POWER APPLICATIONS

This paper deals with the simulation and modeling of a radio-frequency (RF) energy harvesting system. In this model, a power source is taken as an antenna that can receive wireless-fidelity (Wi-Fi) 2.4GHz frequency band signals. A load impedance of 1 kΩ is chosen. A single-stage Villard multiplier is implemented for amplification and rectification. The design provides analysis for four matching techniques like inductor-capacitor, inductor-inductor, single stub, and quarter wave transformer. The performance of each matching configuration is compared to visualize the most efficient matching technique using the Advanced Design System (ADS) software. Hardware modeling and simulation is done using the Proteus professional software.
