3D U-shaped yagi uda nantenna for nanoscale applications

Abstract

In this paper, a compact 3D U-shaped Yagi-Uda nantenna with different high permittivity and permeability materials has been studied and compared with variation in the spacing between the elements. Modern communication demands high speed data processing at nanometer wavelength and it is basically relying on the speed and bandwidth of emitters & detectors on the nanoscale. In order to achieve this goal, antenna made of material with high permittivity and permeability dielectrics are required which allow the enhancement of light and high frequency RF communication and sensing. Optical Yagi-Uda nantenna offers unique directive property which mobilizes concept like beam forming and beam scattering and can be predominately useful in various application areas. To fulfill this motive we need to study suitable material technology in order to improve various properties such as gain, return loss, radiated power etc. ANSYS HFSS v15.0 is the software that provides a platform to design the antenna with the changes in dielectric permittivity and permeability and the spacing between the elements is relying on the operating wavelength.
