Paper Abstract

In this paper, new design of Yagi-Uda nano-antenna (NA) based on ellipsoid shape is introduced and numerically analyzed using 3-D finite difference time domain method (3-D FDTD) via Lumerical software package. The NA parameters are optimized using the particle swarm optimization (PSO) algorithm to achieve high directivity at a wavelength of 500 nm for wireless point-to-point applications. To illustrate the performance of the proposed antenna, different radiation parameters such as radiation pattern, directivity, and radiation efficiency have been studied. The optimized ellipsoid nano-antenna shows a directivity of 22.36 which is enhanced by 86.3 % relative to the conventional spherical counterpart. Moreover, the fabrication tolerance of the reported design is studied to ensure the accuracy of the introduced NA parameters to the fabrications errors.
