Paper Abstract

In this paper, study of novel design of gold tip slotted square patch nanoantenna placed over silica substrate has been done. Designed antenna is optimised on basis of various geometrical parameters such as antenna length, thickness, gap between the antenna etc. using COMSOL Multiphysics a finite element method (FEM) based simulation software for the near field analysis. Both single and coupled tip slotted square patch antenna are analysed and the effect of slot on the antenna performance is also studied. The operational wavelength is in the near and mid infrared range of the electromagnetic (EM) spectrum as nanoantenna finds various applications in the field of near field microscopy, spectroscopy, infrared(IR) detection, waste energy and solar energy harvesting.
