The proposed system mainly framed by the comparative analysis has been done about various designs reported in works considering the trend of performance across different designs. This paper presents the design and prototyping of an IoT-enabled MIMO antenna system optimized for future 5G wireless communication networks. The study focuses on the development of the antenna with some attention paid to the most significant parameters: impedance matching, gain, radiation patterns, and isolation to increase data rates, coverages, and reliability in 5G applications. This paper includes the study of the dependence of the number of elements, frequency band, bandwidth, and gain values and an investigation of frequency spectrum requirements with cell sizes for 5G FR1 and FR2 stages. The work also investigates bandwidth and frequency efficiency across different categories of antennas, and MIMO antenna classifiers were used to analyze frequency vs. bandwidth characteristics for specific applications. This also measures the relationship that exists between the number of elements and gain levels associated with antennas. Also, measurements of gain at dBi coupled with radiation performance are carried out in different levels of frequency-GHz.
