Performance evaluation of the electromagnetic behavior of the bundle SWCNTs with circular geometry

This paper presented for the purpose of study and estimates the fundamental electromagnetic properties of the bundle of single-walled carbon nanotubes with circular geometrical structure. The bundle of single-walled carbon nanotubes (SWCNTs) dipole antenna will be employed for this purpose by using Drude method at THz frequency range. The armchair-single-walled carbon nanotube (armchair- SWCNTs) will be utilized in this work, Due to their metallic conducting properties, in order to configure the bundle of SWCNTs. The bundle that will be investigated in the current work is filled by identical SWCNTs having the same radius and same length. The radiation pattern, s11 parameters and antenna directivity of bundle SWCNTs dipole antenna are presented in this paper. Based on the performance evaluation presented in this paper, the bundle of SWCNT dipole antenna is a good candidate for the nano-antenna application instead of SWCNT dipole antenna. Also, the problem that associated with SWCNT dipole antenna can be reduced by the bundle. All results in this work explained that the bundle of SWCNTs can be used to design bundle of SWCNTs dipole antenna in a wide THz frequency band. The performance of this dipole antenna will be evaluated by using Computer Simulation Technology (Microwave studio) CST (MWS), which presents and analyses the key parameters of the antenna.
