Design and Simulation of a High Performance Dual Band MIMO Antenna for Wireless Applications

The purpose of this research is to demonstrate a fractal shape MIMO antenna that may be used for wireless applications. Two frequency ranges intended for different wireless applications where the suggested antenna resonates including 6.8 GHz, and 11.8 GHz. The solo unit antenna diameter of the presumed twin-band antenna is 20 mm × 10 mm × 1.6 mm. At 6.8 GHz, and 11.8 GHz, the antenna’s gain is found to be 7.1 dBi and 6.3 dBi. The overall simulated radiation efficiency is found above 80%. The nominated MIMO antenna's over all dimension was 20× 17mm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup>, which was engraved on a Fr-4 substrate at a height of 1.6mm, ε<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">r</inf>= 2.2 and designed based on the parameters of length (mm), width (mm), and thickness (mm) using CST STUDIO SUITE 2019 software. Our comparison analysis demonstrates that the little size of the recommended antenna’s straightforward design, strong gain, and radiation efficiency make it an excellent option.
