This research work addresses the challenges associated with isolation techniques in MIMO antenna design. The proposed 4-port L-Slotted Ultra-wideband (UWB) Multiple-Input Multiple-Output (MIMO) antenna design aims to offer a simple and compact solution that naturally ensures isolation between antenna elements. By employing innovative design strategies, notably incorporating L-Slotted structures, the research aims to extend the impedance bandwidth to 14.28 GHz, with a notch band covering the X-band and the lower portion of the Ku-band. The antenna's performance is evaluated by examining key metrics such as reflection coefficient ( – 10 dB), isolation ( – 20 dB), and diversity parameters. The proposed antenna achieved notable maximum |S11| of 22.77 dB at 6.945 GHz, a peak gain of 10.61 dBi, ECC 0.0044, TARC – 10 dB, and a diversity gain of approximately 9.999 dB. The wide impedance bandwidth and compatibility with various frequency bands make this antenna design adaptable to diverse applications and environments, providing flexibility for different system requirements. With its compact and efficient design, this antenna can be integrated into Internet of Things (IoT) devices and smart appliances, enabling reliable and high-speed wireless connectivity. Wide impedance bandwidth makes this antenna design suitable for various wireless communication applications, including Wi-Fi, 5G, and beyond. |
