Abstract

In this paper, rectangular and circular shape antennas are designed for analyzing the performance characteristics of an antenna. Semiconducting Carbon Nanotube (CNT), Metallic Carbon Nanotube (MCNT), Copper and Graphene are considered as the patch materials. There are different parameters but conductivity has been taken to differentiate between these patch materials. Each patch material has its own conductivity through which a comparative analysis has been implemented in this paper. Different types of parameters like Return loss, Gain, Voltage Standing Wave Ratio (VSWR) and Radiation pattern are obtained and discussed to analyze the results. Resonant frequency for the metallic CNT rectangular patch antenna has been noticed at 2.85 GHz. Resonant frequencies of 2.87 GHz and 2.88 GHz has been obtained for Copper and Graphene patch antenna in rectangular shape. Comparison of simulated results has been obtained in the same manner for circular shape antenna. A resonant frequency of 18.74 GHz has been noticed for patch antennas in circular shape. On comparing the simulated results, Graphene patch antennas has been observed to deliver best performance.
