Investigation on Characteristics of Metamaterials by Using Metallic Rod Structure for Antenna Engineering

Abstract

In this research, the investigation of metallic rod type metamaterials is presented. In the study, the simulation and numerical analysis are performed to analyze the classification of metamaterials when the metallic rods are arranged in various patterns, including permittivity, permeability and reflection index. From the simulation and numerical results, it was found that metallic rod is classified in epsilon near zero characteristics when metallic rods are arranged with double and three layers. Electromagnetic properties of proposed structure are electromagnetic band gap and partially reflective surface at the designed frequency. In addition, the band gap of the proposed structure is studied. The proper layer number and pattern of metallic rods structure can control the operating frequency band. The structure can be future applied such as improving characteristic of antenna and electromagnetic interference. © 2022 Wydawnictwo SIGMA-NOT. All rights reserved.
