Abstract

This paper provides a comprehensive characterization of a graphene based microstrip antenna which shows plasmonic behaviour at terahertz (THz) frequency spectrum. The study focuses on analysing the behaviour of Surface Plasmon Polariton (SPP) waves in graphene sheets through the design and analysis of a rectangular patch antenna. The unique properties of graphene are analysed, and a thorough numerical and analytical investigation of SPP wave propagation in graphene is conducted. The dispersion equation, as well as the intraband and interband conductivity of graphene, are explained using Kubo's formula. The patch antenna is designed to operate at a resonant frequency of 0.55 THz, and its electrical characterization is performed using the High Frequency Structure Simulator.
