Performance Investigation of Loop and Helical Carbon Nanotube Antennas

This paper introduces new configurations for the carbon nanotube (CNT) antenna, namely loop and helical CNT antennas. The design of these antennas depends on the geometry which consists of one or more CNT elements. To model these antennas, the CNT is replaced by an equivalent solid wire having frequency dependent complex permittivity which reflects that of the CNT material. The developed CNT model can be used easily with commercial electromagnetic software solvers to predict the characteristics of these advanced antennas. The simulation results reveal that CNT antennas exhibit multiband operation and this property is more emphasized when loop or helical configurations are used
