"Design of Compact Circular Microstrip Patch Antenna by Using Metamaterial Structure"

Abstract

In today’s modern communication industry, antennas are the most essential components required to create a communication link. Micro strip antennas are the most suited for aerospace and cellular applications because of their low cost, light weight and low power handling capacity. The paper provides a detailed study of the design of compact circular microstrip patch antenna by using metamaterial structure.The metamaterial antenna is designed in FR4 Epoxy substrate with dielectric constant of 4.4, height of the substrate is 1.6 mm with a circular patch. Metamaterial analysis and simulation was done using HFSS 2022 R2 Software yields a best results of gain at their operating frequency (fr) and return loss. Desirable voltage standing wave ratio between 1 and 2 is achieved, after introducing artificial magnetic unit cell metamaterial on the circular patch antenna. Hence multiband antenna is obtained used for Sub-6 GHz 5G applications, operates in S, C, X, Ku bands.
