Design and optimization of UWB antenna for the 5G mobile communication applications using a fuzzy expert system

This study proposes a small MIMO antenna design with excellent isolation for wireless applications in 5 G-linked devices. This 45x40mm2 MIMO antenna system comprises two elliptical antennas that are symmetrically placed next. For UWB applications, a MIMO antenna with excellent isolation is suggested. The proposed MIMO antenna comprises two symmetric slot antenna components to improve impedance bandwidth. A decoupling network slot is added in the common ground to enhance isolation at the lower band. The suggested antenna would offer better than 20 dB isolation throughout the operational range of 1.5 to 9.5 GHz. The radiation patterns, peak gain, envelope correlation coefficient, mean effective gain and diversity gain of the UWB MIMO antenna will all be considered. The proposed simulation model is performed in matlab software and aims to improve the knowledge of the best technology, which is currently determined based on subjective degrees. The technologies of the generations of the Internet are constantly evolving after 4G. This work proposes a new Fuzzy Expert System for the evaluation and quantitative analysis of different Internet generations to determine the best generation of networks concerning the input parameters of the system are represented by frequency, service, multiplexing, data rate and period.
