Nature inspired fibonacci sequence microstrip patch antenna for energy harvesting applications

Abstract

In this paper, design and simulation of Nature Inspired Fibonacci sequence golden spiral antenna is presented. It is based on the snail’s shell structure which is frequently found in nature. The proposed antenna geometry has its unique design and it is used for energy harvesting applications. For energy harvesting applications rectenna is designed which has an antenna, matching circuit, voltage doubler circuit and load. The antenna is designed in CST (computer simulation technology) microwave studio software. Using CST software S-parameter, surface current, E-field, H-field are simulated and results are analyzed. The antenna is simulated in 3 GHz to 10 GHz frequency band and achieves multiband return loss characteristics and positive gain at respective frequencies.
