This paper presents a compact ultra-wideband (UWB) MIMO antenna enhanced using metamaterial structures. A two-element antenna system is designed with very close spacing, where split-ring resonators (SRRs) are introduced to reduce mutual coupling and improve isolation. The proposed antenna operates over a wide frequency range (1GHZ-5GHz) with good impedance matching, high efficiency, and stable radiation characteristics. Key performance parameters such as envelope correlation coefficient (ECC) and diversity gain (DG) show significant improvement, making the design suitable for 5G and IoT applications. The results demonstrate reduced size, enhanced bandwidth, and better overall system performance
