Solar energy harvesting systems including an antenna and a rectifier are called rectenna. solar energy harvesting in this system is based on generating a time varying current on the surface of antenna by the time of radiation of an electromagnetic wave to this type of nano-antenna, leading to producing a potential difference at the antenna feed site where using a suitable rectifier, an appropriate DC power gets produced. The efficiency of this system depends on the design, geometry, dimensions, and characteristics of the nano-antenna, conductor, and rectifier used in it. This paper deals with the design and simulation of a silver helical nano-antenna to study the input impedance, radiation efficiency and polarization efficiency of the nano-antenna. The studied wavelength range is from 300 to 300 nm. Input impedance, because of its geometrical structure, has relatively linear behavior in all wavelengths except the wavelengths below 500 nm. In this particular scheme, the obtained efficiency of radiation from 700 to 2600 nm is more than 80%. Polarization efficiency is almost 100 percent in most bandwidths which results in increase of solar energy harvesting.
