Abstract: The rapid evolution of 5G technology requires advanced antenna systems that ensure high isolation, compact design, and efficient performance. This project focuses on the development of a compact MIMO antenna with enhanced isolation for 5G applications. The proposed design integrates innovative isolation techniques, including defected ground structures (DGS), electromagnetic bandgap (EBG) materials, and decoupling networks, to minimize mutual coupling and improve signal integrity. Additionally, optimized element positioning and polarization diversity are employed to enhance spatial multiplexing and reduce envelope correlation. The antenna is designed to achieve high gain, wide bandwidth, and superior diversity performance, making it suitable for compact 5G devices. The design is simulated using HFSS, and extensive parametric analysis is conducted to validate its performance. The results confirm significant isolation improvement, enhanced efficiency, and reliable communication performance, demonstrating the antenna's suitability for next-generation wireless applications. Keywords: 5G MIMO, High Isolation, Mutual Coupling, DGS, EBG, Decoupling Networks, Spatial Multiplexing, HFSS Simulation, Wireless Communication.
