A Novel Compact Circular Hybrid Plasmonic Nano-Antenna for Optical Applications

In this article, we propose a circle shaped hybrid plasmonic nano patch antenna with SOI (Silicon on Insulator) configuration in a foot print area of 1100 x 800 nm2. It has been designed for operation in frequency range of 160-240 THz and to resonate at 193.5 THz. For the purpose of impedance matching proposed circle shaped antenna was inset fed by SOI configured waveguide and has been implemented using FEM based solver (CST MWS) and observed that the proposed antenna results in bandwidth, gain and efficiency of 67.6 THz, 5.25 dB, 91.10%, occurring at resonant frequency 193.5 THz. The suggested antenna is possible for practical realization and can be manufactured with the aid of standard semiconductor fabrication processes. The proposed antenna can be used for numerous chip scale applications like photoemission, photo detection, heat transfer, optical sensing, energy harvesting and scattering.
