The Evolution of Terahertz technology led to focus of Scientists and Researchers on this technology field. Terahertz region lies between optics frequency range and electronics, so THz frequencies are lowest frequencies make the free space conventional optics enable still be utilized before microwave components adopt. In this paper, CST studio suite 2018 simulator is utilized to simulate and design a new Microstrip Wi-Fi-shape Nanoantenna (MWNA) & Microstrip Wi-Fi-shape Slot Nanoantenna (MWSNA). Reflection coefficient (S11), Directivity, Gain and Bandwidth are computed. The results that achieved working at Terahertz frequencies in Nano size. The Bandwidth of MWNA design and the MWSNA design working in the range of (103.3-110.3 THz) and (124.5 -127.8 THz) respectively. The Microstrip nanoantenna that utilized consist of three layers, Patch made from Gold, Substrate layer that utilized Silicon and Ground plane layer made from Gold. So the applications of these bands of THz frequencies work at visible region and near infrared (IR).
