Design of an Efficient RF Energy Harvesting System at 900 MHz

Abstract

In this paper a more efficient Radio Frequency(RF) energy harvesting system is designed at 900 MHz of ISM band. A schottky diode based Dickson voltage multiplier is used for enhancing the output DC voltage. The output efficiency is tested at the input power range from −10dBm to 40dBm using 1st, 2nd and 3rd stages of the multiplier. The maximum efficiency of the system is achieved at 10dBm which is 84.18 %.
