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).
The ongoing deployment of 5G cellular systems is continuously exposing the inherent limitations of this system, compared to its original premise as an enabler for Internet of Everything applications. These 5G drawback...

In recent years, finger vein recognition has taken a noticeable attention. It is greatly employed for many applications due to its multiple advantages; for example: small and easy to use scanning device, its accuracy and convenience compared to other hand-based biometric models. For years researcher presented promising finger vein recognition approaches, nevertheless, there are problems and challenges in finger vein localization, feature extraction and identification. In this paper, we study twenty two finger vein recognition systems and view the methods and the techniques for which these systems built to serve. the variety of methodologies of these systems are reflects the differences in accuracy and performance for which it is vital to know which presented methods and proposed ways to reduce the outcome; so that more suitable techniques to be produced for building more robust systems.
