Abstract

The present study proposes to investigate the properties of graphene based nano patch antenna considering the semi-infinite, geometries of the graphene attaining zigzag and armchair structures. The antenna designs are simulated on HFSS software and the performance is analyzed in terahertz band based on the different electronic properties. Depending on the edge shapes of structure obtained after cutting the infinite graphene sheet, arrangements formed are named as the zigzag and armchair. As these configurations exhibit different electronic properties, it is suggested that the respective graphene antenna will also lead to varying radiations properties. It is evident from the various results in terms of return loss, gain, radiation efficiency and bandwidth that the graphene antenna based on zigzag arrangement realizes better characteristic as compared to armchair arrangement.
