This chapter focuses on the design and analysis of a unique flexible, transparent, and wideband 4-port MIMO antenna with a connected ground plane, specifically tailored for Sub-6 GHz 5G and WLAN frequency bands. The chapter starts by discussing the single antenna geometry and its evolution mechanism, along with the incorporation of the MIMO configuration and isolating structure. Through comprehensive analysis, this chapter demonstrates how the antenna’s geometry, material selection, and fabrication techniques meet the stringent requirements for impedance bandwidth, gain, radiation efficiency, and radiation patterns. To validate the design and analysis, numerical computation and experimental measurement studies are employed, providing reliable results and ensuring the antenna’s performance. Additionally, the chapter presents a detailed bending analysis, evaluating the antenna’s behavior under different bending conditions, and examines the MIMO diversity performance parameters for the desired operational frequency bands. By combining simulation and measurement studies, this chapter showcases the effectiveness and performance of the flexible MIMO antenna design, making it a valuable resource for researchers and engineers involved in Sub-6 GHz 5G and WLAN applications.
