Abstract

Based on the models of single walled carbon nanotubes (SWCNTs) and bundled SWCNTs antennas, we analyse the spectral efficiency of an SWCNT bundled dipole antenna based MIMO system in the Terahertz band. Two scenarios are considered: the large scale MIMO and the conventional scale MIMO. It is found that, in order to get the maximum spectral efficiency, the CNT bundle size should be optimized to obtain a tradeoff between antenna efficiency and the number of antennas for a given area. This work also takes into account the random fluctuation in the bundle size during the CNT bundled antenna fabrication which reduces the system spectral efficiency.
