Analysis of graphene based triangular nano patch antenna using photonic crystal as substrate for wireless applications

The goal of this paper is to explore the effects of two dimensional photonic band gap (PBG) crystals substrate on the performance of a graphene based triangular nano patch antenna in terahertz region (1-3 THz). Graphene as patch conductor on photonic crystal has been used as substrate material for high bandwidth, radiation efficiency and highly directional resonant antenna. Good impedance matching is achieved at the resonating frequencies with 5.6% bandwidth. The radiation characteristics including radiation efficiency and absorption cross section show significant improve on account of using PBG crystals substrate for graphene based patch antenna. The simulation has been performed using High Frequency Simulator Software (HFSS), which is a commercially available electromagnetic simulator based on finite element method technique.
