Impact of Antenna Element Directivity and Reflection-Interference on Line-of-Sight Multiple Input Multiple Output Terahertz Systems

Abstract

Terahertz (THz) communications are envisioned as the future of wireless communications. In order to combat the high path loss experienced by THz signals, beamforming using multiple-input multiple-output (MIMO) systems has been suggested. In this paper, two practical challenges for THz line-of-sight MIMO systems are investigated for the first time: the impact of antenna element directivity and self-induced inter-symbol interference on performance. Additionally, experimental results are presented to verify the findings.
