Enhancing the Performance Characteristic of Patch Antenna using Split-Ring Resonator Metamaterial

Abstract

A patch antenna preferred for the utilization of ultra wide-band operations is designed to enhance its characteristics and it is based on the compound right-left handed transmission process. This antenna model will be designed using the concept of metamaterials and practically simulated using HFSS (High-Frequency Structural Simulator) software. Here three left-handed metamaterial split-rings are aligned in one axis to bring a single convention patch to a different version. This split-ring resonator is refashioned a little bit from the original pattern and used along with capacitively loaded strips. Besides a coplanar waveguide is introduced along the sides of the feed line to decrease the trace width that can lead to some distortions in the transmission line. The main objective involved in this work is to represent a simple patch antenna by shaping its patch in such a manner to improve gain and bandwidth that will produce a better quality factor.
