Department of Electrical and Electronic Engineering, BRAC University Gold nanoparticle absorption Scattering Near field Far- field Nanoparticle plasmon coupling Field enhancement Directivity Gain and FDTD simulation Time-domain analysis. Finite differences. This thesis is submitted in partial fulfilment of the requirements for the degree of Master of Science in Electrical and Electronic Engineering, 2021. Cataloged from PDF version of thesis. Includes bibliographical references (pages 94-96). In this study, we have investigated the optical property of single and coupled plasmonic antenna using the finite-difference time-domain (FDTD) method. The extinction efficiency, plasmon coupling, and near and far-field enhancement have been investigated as a function of size and shape for dipole, bowtie, and rectangular nanoantenna. Additionally, we have investigated the patch and probe antenna in terms of return loss, near field power, input impedance, and directivity and observed how antenna parameters can be tuned by changing their dimensions. The findings of this study will be helpful to design a cost-effective and efficient plasmonic nanoantenna by replacing the typical RF antenna in terms of size, efficiency, cost, and convenience.
