Graphene nanoribbon based antenna for terahertz band communication

Nanotechnology has enabled the use of Nanosized devices for various purposes i.e. biological, industrial, and military and especially in communication field.By using graphene the antennas can be implemented in nano scale. And the miniature antennas would work more efficiently than the conventional antennas. The miniature device can transmit data in terabyte scale. Conventional antennas would require very high frequency which is quite unfeasible. But the slower movement of electrons in graphene would enable the grapheme nano antennas to operate at a feasible frequency.[1][2]. In this paper we designed, Graphene nano ribbon based antenna that would operate in terahertz band and investigatedits radiation characteristics in the 2.45-2.98 THz band. The proposed antennas are also compared with the conventional antennas operating in terahertz band. The antenna is simulated by using the finite element method based simulator -CST (computer simulation technology).
