Parth Thakar, Ameya Kadam . Review Paper on RF based Energy Harvesting System. Communications on Applied Electronics. 7, 26 ( Feb 2019), 1-7. DOI=10.5120/cae2019652811
As the law of conservation of Energy states that energy can neither be created nor be destroyed, it can only be converted or transformed from one form to another, moreover there are various sources of energy like solar, wind, geothermal etc. The purpose of this paper is to put light on radio frequency based energy harvesting systems. The said RF energy is currently transmitted from various sources/transmitters which include mobile base stations, mobile, telephone, TV/radio broadcast stations and handheld radios. The propensity to gather or harvest RF energy from the committed sources empowers or authorizes wireless charging for low power appliances or devices which furthermore results in better product design dependableness and utilization. The battery operating systems can be charged gradually and slowly to abolish battery replacements or to extend battery durability disposable batteries can be used. The battery free systems i.e. RF energy based devices can be designed to work upon availability i.e. when the sufficient charge is accumulated. In all the cases mentioned above the devices or the appliances can be operated without the usage of cables battery panels connectors which can make these devices more mobile and portable while operation and charging as well. All this and more can be achieved by RF based energy harvesting and main cause or reason to harvest RF based energy is that it is consequentially FREE energy. The sources of RF energy are increasing day by day like mobile based transmitters from which more and more energy can be harvested. This paper more importantly focuses on parameters to design the system, methods, different frequency ranges that can be utilized and the respective circuitry for converting Low voltage output to High voltage for various applications using RF based energy harvesting.
