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...
In this paper, a compact printed antennas with a band-stop characteristic for ultra-wideband application are proposed. The dual-oval shape is introduced to reduce the size of the dimension, thus make it more compact. In order to increase the impedance bandwidth of the proposed antenna, a partial ground and circular slot are used. By attaching an inverted Y-shaped open-circuited stub in the circular...
A high gain and high directive microstrip patch antenna formed from Barium Strontium Titanate (BST) ceramics and covered with dielectric substrate has been investigated. The Computer Simulation Technology (CST) Microwave Studio is used for the simulation. We measured the gain and directivity of antennas with and without a superstrate and found that the gain of a single BST array antenna with a superstrate...
