Design and Analysis of Compact Pentagonal Hybrid Plasmonic Nano-Antenna

In this paper, a hybrid plasmonic pentagonal shaped nano patch antenna with SOI (Silicon on Insulator) configuration has been proposed in a foot print area of 1100 x 800 nm2. It has been designed for operating frequency range of 160-250 THz and to resonate at 193.5 THz. For arrant impedance matching the proposed pentagon shaped antenna is inset fed to SOI configured waveguide. Through, the numerical simulation using CST microwave studio suite, the proposed antenna results bandwidth, gain and efficiency as 77.34 THz, 5.354 dB, 91.10%occurring at operating range. With the help of standard semiconductor processing technology the proposed pentagonal shaped nano antenna can be realized practically. The proposed antenna could be used for number of chip scale applications such as photoemission, photo detection, heat transfer, optical sensing, energy harvesting and scattering.
