Performance Analysis between SWCNT and Copper Antennas in High Frequency Region

IEEE
A theoretical investigation is carried out to predict the radiation characteristics of single walled carbon nanotube (SWCNT) and bundled SWCNT antenna in the terahertz region. Simulated results indicates that radiation efficiency of a bundled SWCNT antenna is much higher than SWCNT antenna which is above 80%. In the terahertz region, the bundled SWCNT dipole antenna is found more efficient than that of copper dipole antenna.

Analysis of Bending and Human Body Effects on Sleeve-Badge Textile Antenna Performance

IEEE
This article presents the effects of bending and human body interaction with Sleeve-Badge textile antenna on performance. The antenna resonance frequency has been notably shifted due to bending and the human body interaction. The simulated result indicates that there is a significant effect on SAR values under different bending conditions and the distance of the antenna from the human body.
