Abstract

Radio Frequency Energy Transfer is a research area of on demand technology, related to sustainability which could turn into a promising alternative to existing energy resources. Energy harvesting 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 Harvesting is rectifying circuit that converts the RF signal to DC signal. In this project an optimum rectifying circuit is designed, simulated by using the Advance Design System (ADS) 2011 software then fabricated and measured in the laboratory. Frequency 2.4GHz are proposed for this project. This rectifying circuit consists of a single stub matching network, voltage doubler and dc to dc converter at the output port of rectifier. The simulation result of rectifying circuit is 6.7V while in the measurement the output result is 6.2V at input signal 20 dBm. When connect with dc to dc converter the output voltage boost to 10.5V at 20 dBm power input.
