Abstract : This paper presents the enhancement of isolation in a compact 2×2 Multiple Input Multiple Output (MIMO) microstrip patch antenna system using RT-Duroid substrate for X-band applications. An inset-fed rectangular patch antenna is designed into a MIMO configuration. However, the initial design exhibits low isolation between antenna elements; therefore, novel metamaterial structures were introduced between the MIMO elements to enhance isolation. These metamaterials validated using the Nicolson-Ross-Weir method, exhibits distinct electromagnetic characteristics. This integration improves isolation from 35 dB to 57 dB, while maintaining a low envelope correlation coefficient (ECC) of 0.000015 and a stable diversity gain of approximately 10 dB at X-band frequency. The proposed design offers enhanced performance, making it suitable for high-efficiency, compact MIMO systems in advanced wireless communication.
