Abstract
An ultra-wideband (UWB) terahertz (THz) graphene plasmonic bowtie antenna is investigated in this paper. Because of its unique electronic and plasmonic properties at THz band, graphene plasmonic bowtie antenna shows excellent performance in THz frequency regime in terms of more stable UWB performance, high miniaturization and easy reconfiguration.The proposed antenna provides an ultrawideband of impedance bandwidth of 340% and stable omnidirectional radiation pattern. Graphene plasmonic bowtie antenna has more than 5 times bandwidth and 22 times less size than the gold bowtie antenna of same operational frequency. Moreover, frequency reconfiguration is easily achievable by variation of graphene chemical potential. The proposed graphene plasmonic bowtie THz antenna can be promising for a wide range of UWB THz applications from sensing to communication.
