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...
This paper aims to investigate the fundamental properties of single-walled carbon nanotubes bundles dipole antenna at THz frequency band by using Drude method. Due to their metallic conducting properties, the armchair-SWCNTs will be utilized in this work to configure the bundle of SWCNTs. The cross section of bundle that will be investigated in the current work can be in a rectangular geometry filled...
This work investigates the fundamental properties of armchair single-wall carbon nanotubes (armchair-SWCNTs) dipole antenna at THz band using Drude method. Due to their metallic conducting properties, the armchair SWCNTs will be utilized in this work. The radiation pattern, s11 parameters, phase velocity and antenna directivity are presented for this antenna. The results demonstrate that armchair-SWCNTs...
A meandered dipole Yagi-Uda antenna with parabolic reflector for 1.575 GHz of the Global Positioning System (GPS) application is presented. The intention of this work is to attain the consequence for optimum presentations of the antenna established to gain, size and directivity. This antenna radiates at the frequency between 1.52 GHz and 1.88 GHz. The gain for this antenna is 4.521 dB at 1.575 GHz...
The investigation on the changes of Specific Absorption Rate (SAR) inside the head due to metallic straight pin with simple braces added is presented in this paper. The finite integration in time domain (FIT) computer simulation technique was used in this investigation. The head is irradiated by dipole sources in front of the Specific Anthropomorphic Mannequin (SAM) face. Parametric studies show that...
