UWB THz plasmonic microstrip antenna based on graphene

Abstract

This paper proposes design and investigates of graphene based plasmonic microstrip antenna for terahertz high speed communication and application systems 0.1-20 THz. The proposed antenna structure composed of graphenebased rectangular patch and transmission line mounted on a grounded silicone dioxide substrate. SPP (Surface Plasmon Polariton) waves that appear in graphene at THz band is analyzed. The proposed antenna simulation was done by using numerical method CST program. The simulation results show the scattering parameter S11 less than -10 dB at frequency band (0.1-20) THz. Also, the presented antenna system has a good gain along the frequency band.

“…Hence, several plasmonic appliances are advised and studied, such as antennas, filters for THz applications. In the correlation with gold or silver, the graphene backings SPP waves at extremely small frequencies in the THz regime [10]- [12]. The SPP wave presents in the noble metals at the nearinfrared and visible frequency of the radio frequency spectrum.…”
