The use of massive antenna arrays for creating extremely directive antenna radiation patterns is considered vital for overcoming high path loss and atmospheric absorption of terahertz links. However, high directivity also results in frequent misalignment of beams due to small-scale/micro-mobility of user equipment (UE), such as shakes and rotations, leading to the spontaneous degradation of SNR level and waste of communications time for the beam searching procedure. In this paper, we make the initial steps to investigate the behavior of terahertz band link characteristics subject to the small-scale mobility of UE. We show that the optimal antenna directivity angle leading to the highest, on average, capacity heavily depends on the micro-mobility pattern of the UE. Further investigations in this area will contribute to the design of robust and high-performance communication systems in the terahertz band.
