RF Energy Harvesting using Efficient Power Management System

Abstract

The paper presents an RF energy harvesting system consisting of a Microstrip antenna, matching circuit, voltage multiplier circuit followed by robust control algorithms for DC-DC signal processing. Here the antenna is fabricated only for the 1800 MHz of the GSM band. The output of the antenna is about 0.3mV at matching circuit output and amplified output for the 5.256V at the output of the voltage multiplier circuit is achieved. Further, the control algorithms help in achieving the optimum maintained output of the entire system.
