Design & Analysis of RF Energy Harvesting System for Energizing Low Power Device

Journal 4 Research - J4R Journal, 2016

Finite electrical battery life is encouraging the companies and researchers to come up with new ideas and technologies to drive wireless mobile devices for an infinite or enhance period of time. Common resource constrained wireless devices when they run out of battery they should be recharged. For that purpose main supply & charger are needed to charge drained mobile phone batteries or any portable devices. Practically it is not possible to carry charger wherever we go and also to expect availability of power supply everywhere. To avoid such disadvantages some sort of solution should be given and that can be wireless charging of mobile phones.[4] If the mobile can receive RF power signals from the mobile towers, why can " t we extract the power from the received signals? This can be done by the method or technology called RF energy harvesting. RF energy harvesting holds a promise able future for generating a small amount of electrical power to drive partial circuits in wirelessly communicating electronics devices. RF power harvesting is one of the diverse fields where still research continues. The energy of RF waves used by devices can be harvested and used to operate in more effective and efficient way.

A Simple Concept of Energy Harvesting Using Radio Frequency

MATTER: International Journal of Science and Technology, 2017

Energy harvesting is a process where certain sources is extracted and converted into DC output by connecting relevant circuits. This energy harvesting technique can reduce the usage of electricity for small power consuming devices. Some of the techniques of energy harvesting is solar energy, wind turbine, radio frequency and vibrations. Radio frequency energy harvesting can be done from the surrounding sources or from dedicated sources. This energy harvesting consists of several stages processing which starts with a 50ohms radio antenna, matching network and rectifier circuit and end as product of DC output. The proposed technique of energy harvesting is by connecting the radio antenna to an L-matching network and then to a single

Design of RF Energy Harvesting System for Energizing Low Power Devices

Progress In Electromagnetics Research, 2012

Electromagnetic energy harvesting holds a promising future for energizing low power electronic devices in wireless communication circuits. This article presents an RF energy harvesting system that can harvest energy from the ambient surroundings at the downlink radio frequency range of GSM-900 band. The harvesting system is aimed to provide an alternative source of energy for energizing low power devices. The system design consists of three modules: a single wideband 377 Ω E-shaped patch antenna, a pi matching network and a 7-stage voltage doubler circuit. These three modules were fabricated on a single printed circuit board. The antenna and Pi matching network have been optimized through electromagnetic simulation software, Agilent ADS 2009 environment. The uniqueness of the system lies in the partial ground plane and the alignment of induced electric field for maximum current flow in the antenna that maximizes the captured RF energy. The design and simulation of the voltage doubler circuit were performed using Multisim software. All the three modules were integrated and fabricated on a double sided FR 4 printed circuit board. The DC voltage obtained from the harvester system in the field test at an approximate distance of 50 m from GSM cell tower was 2.9 V. This voltage was enough to power the STLM20 temperature sensor.

An UHF Wireless Power Harvesting System–Analysis and Design

2011

This paper presents a system to harvest electromagnetic energy from the environment. The proposed solution differs from others already existent in the literature because it makes possible to harvest energy from a large frequency spectrum. Typically the existing energy harvesting systems only gather energy from one specific source, thus not taking advantage of the several RF sources existing in one place. The full system and its components are simulated and implemented, and the results obtained are shown. The system harvest energy from UHF sources, and converts the harvested energy to a DC voltage, in order to feed electronic devices. This conversion is made through the utilization of a voltage multiplier, followed by a voltage regulator.
