The RF Energy Harvesting Antennas Operating in Commercially Deployed Frequency Bands: A Comparative Stud

Abstract

This paper deals with suitable antennas for energy harvesting, which is a growing research field due to the utilization of nowa-days ubiquitous and abundant RF energy. Four types of basic antenna structures suitable for harvesting applications, namely the patch antenna, slot antenna, modified inverted F antenna and dielectric resonator antenna are compared from the view-point of reflection coefficient, efficiency, radiation patterns and dimensions. The frequencies of interest were chosen so that they cover several main wireless systems operating between 0.8 GHz and 2.6 GHz, i.e. GSM, UMTS and Wi-Fi.This paper deals with suitable antennas for energy harvesting, which is a growing research field due to the utilization of nowa-days ubiquitous and abundant RF energy.
