Abstract

Radio Frequency Energy Scavenging is a research area of on demand technology, related to sustainability which could turn into a promising alternative to existing energy resources. Energy scavenging offer a potential solution to the barrier faced by Wireless sensor networks (WSNs) in order to supply power without the need of wiring and also replacement of battery. One of the crucial parts in RF Energy scavenging is rectifying circuit that converts the RF signal to DC signal. In this project a dual frequency of rectifying circuit is designed, simulated, fabricated and measured by using the Advance Design System (ADS) 2011 software. Frequency 1.8 GHz and 2.45 GHz are proposed for this project. This rectifying circuit consists of a single stub matching network, multistage Wilkinson power combiner and voltage doubler. The simulation result of this dual band rectifying circuit is 6.7V while in the measurement the output result is 5.2V at input signal 20 dBm.
