In this paper, an elliptical-shaped microstrip feed super-wideband (SWB) 2-elements MIMO antenna is proposed for high-speed terahertz (THz) applications. It has 2:1 VSWR operating bandwidth from 0.33-10THz (187%) with 19dBi peak realized gain. Radiation Efficiency is also greater than 70% throughout SWB bandwidth. The 2-element MIMO antenna is designed with a compact size of 1000x1400x101.29 mu m(3) on RT5880 substrate having relative permittivity of 2.2. Simulated results of antenna-like return loss, isolation, and diversity performance parameters (ECC, DG, TARC, etc.) are in an acceptable range. Therefore this antenna is useful for B5G, vehicular communications, Imaging, 3D printing, Terahertz wave Radar, Health care, and Astronomical radiometric application.
