Abstract :
In this study, a novel design of nano-antenna for energy harvesting is proposed and analysed using three-dimensional finite difference time-domain method. The new design consists of three elements nano-antenna with elliptical shape and with air gap. The numerical simulations are investigated for improving the harvesting efficiency of the nano-antennas within the wavelength range from 400 to 1400 nm. The suggested design has high efficiency of 74.6% at 500 nm where the irradiance of the sun is maximum. The proposed nano-antenna shows an improvement in the harvesting and the total harvesting efficiency over the conventional dipole antenna by 15 and 32.7%, respectively.
