Design of Dual Band RF-DC Energy Harvester
Design and implementation of an RF-DC rectifier for use in RF Energy Harvester which will utilize various high frequency sources present in air to power robust low voltage circuit is presented. The harvester is capable of extracting energy from multiple frequency band to output a steady DC. Only commercial off-the-shelf components were used to materialize the proposed circuit. The paper starts with introduction to energy harvester and talks about some prospective uses. Later design approach to the energy harvester is discussed along with subsequent behavioral model. Expected theoretical behavior is followed by methodology of selecting off-shelf component. Finally, the behavior of prototype circuit is compared against expected behavior obtained from circuit model. Simulation was conducted using Advanced Design Studio (ADS) produced by Keysight EEsof EDA and prototype was built in house at technology lab.
