The development of the communication systems comes from the wide application of these systems in our daily life .
Antennas are found around us in abundance when we are in the midst of communicating either locally or globally via radio frequencies or microwave technologies. Since the inception of classical electromagnetics to the wonders of modern electromagnetism antennas in any size or form have and are still working diligently to uphold their purpose,that is, to convert the electromagnetic energy available in free space into confined electric signals and vice versa. As the telecommunication industry is reaching new technological heights, antennas in any size or form have and are still working diligently to uphold their purpose,that is, to convert the electromagnetic energy available in free space into confined electric signals and vice versa. As the telecommunication industry is reaching new technological heights, the demand for energy consumption is also surging,resulting in an increase in environmental problems in the form of carbon emissions One proposed solution is the concept of “green communication,” which primarily aims at improving the energy efficiency while reducing the CO2 emissions and energy consumption of communication networks In order to realize this concept, researchers are now persuaded on designing antennas by utilizing the electromagnetic spectrum in the high frequency bands (THz), which
fulfills the bandwidth hunger requirements of smart devices, provides low cost designs with high connectivity, and satisfies the consumer needs while keeping the environment clean and energy consumption to a minimum. The antennas designed in the THz regime are given the name of optical antennas.
And this kind of antenna's applications wasn't just in the communication but it omit this edge and have applications in the solar systems to absorb the light waves . and because of it’s range that idecate to fabricate it in nanno dimension
