        abstract = {The rapid growth of modern wireless communication and radar systems has increased the demand for compact multiple-input multiple-output (MIMO) antennas with high isolation, improved bandwidth, and enhanced radiation performance. However, conventional MIMO antenna configurations often suffer from strong mutual coupling between closely spaced antenna elements, which degrades system performance, in range. To overcome these limitations, this project proposes the design and development of a metamaterial based high isolation MIMO antenna for S-band applications. The proposed antenna system employs engineered meta material structures to suppress surface waves and reduce electromagnetic coupling between antenna elements. By incorporating meta material unit cells between the radiating elements, the isolation is significantly enhanced without increasing the overall antenna size. This approach enables compact antenna design while maintaining high gain, improved impedance matching, and stable radiation characteristics. The meta material structure effectively modifies the electromagnetic properties of the substrate, leading to better control of near-field interactions and improved MIMO performance parameters such as envelope correlation coefficient (ECC) and diversity gain. The antenna design is simulated and optimized using electromagnetic simulation tools, and a detailed parametric analysis is carried out to study the effects of meta material geometry, element spacing, and substrate properties on isolation and bandwidth. The proposed MIMO antenna is intended for S-band radar and wireless communication applications, where compact size, high isolation, and reliable performance are essential. Overall, the meta material-based approach offers an efficient solution for next generation high-performance MIMO antenna systems. These antennas adapt to dynamic environments and improve the gain and reducing the space for exposed hardware. Overall, they represent the future of antenna technology.},
