RF Energy Harvesting Using Transparent Antenna for IoT Application

Abstract

This paper presents a broad band fully transparent antenna for radio frequency energy harvesting. This antenna is used for powering internet of things low power devices especially in the smart museums. The proposed antenna has a high transparency that reached to 90%. So that it can be fixed on museums glass windows, buildings or cars without any effect on the eye vision and decoration. Moreover, it is the first time to fabricate a fully transparent antenna in Egypt. So, the proposed antenna has simple structure just to master the fabrication technology. Glass is used as a substrate and the indium tin oxide is used as a transparent conductor. The proposed antenna has low cost material and fabrication technology. The same proposed antenna is printed on opaque FR4 substrate which is used for comparison. The chosen opaque substrate has thickness and dielectric constant close to the transparent glass substrate.
