Development of Compact MIMO Antennas with Enhanced Isolation and Diversity Parameters for Efficient 5GA Communication

The deployment of 5G networks demands antenna systems that strike a balance between compactness, efficiency, and robust performance. This project presents a novel compact MIMO antenna design engineered to enhance isolation and diversity parameters, addressing key challenges in modern communication systems. By employing innovative isolation techniques such as electromagnetic bandgap (EBG) materials, and decoupling networks, the proposed design minimizes mutual coupling and improves signal integrity. Additionally, strategic element positioning and polarization diversity methods are integrated to optimize spatial multiplexing and reduce envelope correlation. The resulting antenna system not only ensures high gain and broad bandwidth but also maintains a minimal footprint, ideal for space-constrained 5G devices. Rigorous simulation and prototype testing validate its effectiveness, showcasing improved isolation, enhanced diversity performance, and superior communication reliability. The parametric study of the proposed antenna was carried out using the HFSS simulator. Key Words: MIMO Antenna, Electromagnetic Bandgap (EBG), 5G Technology, HFSS Software
