▎ 摘　　要

A tunable terahertz nanoantenna based on graphene is presented. The proposed antenna has a characteristic of dynamic frequency reconfiguration, high miniaturization, easy integration, low reflection coefficient, and good omnidirectional radiation pattern. The attractive properties of the graphene antenna has the potential to be used in nanoscale wireless communications and sensing systems. (c) 2014 Wiley Periodicals, Inc.
