Design modeling for education as a mimo

This paper presents the design, simulation, fabrication, and testing of a novel MIMO antenna optimized for wideband applications, with specific suitability for standards such as Bluetooth, Wi-Fi, LTE, and IEEE ۸۰۲.۱۱ a/b/g/n. The antenna exhibits strong impedance matching over four operating bands: ۲.۱۷-۲.۶۲ GHz, ۳.۶-۳.۸ GHz, ۶.۶۸–۸.۴۲ GHz, and ۸.۸۵-۲۴.۸۵ GHz. The design incorporates a parasitic element to enhance isolation and reduce mutual coupling between ۱×۲ antenna elements, achieving an isolation level exceeding ۲۱ dB across the operating bands. Simulated and measured results are in close agreement, with minor deviations attributed to fabrication tolerances and connector losses. The antenna maintains a stable gain between ۳.۹ dB and ۶.۹ dB, demonstrating excellent omnidirectional and bidirectional radiation patterns in the E-plane and H-plane, respectively. These results confirm the antenna's potential for use in modern wireless communication systems requiring compact designs, high isolation, and wideband performance.
