Optimizing RF energy harvester design for low power applications by integrating multi stage voltage doubler on patch antenna

Abstract

The results of this paper based on analysis of design patch antenna with minimum dimensions and permittivity acquirable that produces a maximum power output. Since RF (Radio Frequency) energy harvesting is a recurring theme which enormously effective and applicable in occasions where remote charging and wireless power transmission take place. The potential use of RF energy was investigated experimentally. The aim of this work is to investigate the power levels that can be harvested from the air and processed to achieve the energy levels that are sufficient to charge low power electronic circuits. An RF collection system has been specifically designed, constructed, and shown to successfully collect enough energy to power circuits. For an equivalent incident signal the circuit can produce required voltage across load. This voltage can be used to power low power sensors in sensor networks ultimately to replace the batteries.
