Description
Summary:Hybrid plasmonic optical nano-patch antenna (ONPA) was examined for operating at the frequencies 125 - 250 THz by employing the finite element method (FEM) applied in Ansoft High-Frequency Structure Simulator (HFSS). The antenna proposed has a wide bandwidth of 67.66 THz. (166.04THz-233.7THz) for the slots thickness Wc=200nm, Wf=100nm, and d=0 nm. The results show the 0.03Ω imaginary part of reactance, an input impedance of 50.4Ω, and real part of input resistance at the operation frequency. Electric and magnetic field distribution and far-field pattern at resonating frequencies (174.5, 200.5, 219.6, 229.6) THz have been studied. The maximum gain of 17.3 dB was obtained for the resonance frequency of 219.6 THz. Performance of antenna is in comparison to previous configurations. The antenna arrays are proposed in one and two dimensions to suitable optical frequencies applications.
