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.
