This paper presents an equivalent single conductor (ESC) model for multi-wall carbon nanotubes (MWCNTs) using transmission line theory. Based on the model, for the first time, it gives the radiation properties of the symmetrical dipole antenna of MWCNTs. The results show that, for 1V excitation and 100 nm length, the resonant frequency of the antenna is in the terahertz band, and with the number of MWCNT shells increasing, the radiation resistance, the resonant frequency and the radiation efficiency increase accordingly at the same time. We can also find unique feature of that return loss of the antenna is fairly high and the radiation efficiency is fairly low compared with traditional antennas.
