Abstract: The rapid evolution of wireless communication technologies necessitates the development of compact, high-performance antennas capable of supporting the high-frequency demands of 5G and future 6G systems. This work presents the design and analysis of a compact 2×2 Multiple-Input Multiple-Output (MIMO) microstrip patch antenna, optimized for millimeter-wave applications. The proposed antenna, with an overall footprint of 12.83 mm × 12.30 mm, features uniquely branched radiating patches and T-shaped feed lines, enabling operation over multiple bands from 10 GHz to beyond 80 GHz. S-parameter analysis, Voltage Standing Wave Ratio (VSWR), far-field radiation patterns, and 3D gain visualization confirm the antenna's wideband performance, high radiation efficiency, and suitability for integration in IoT and vehicular platforms. The design process was carried out using CST Studio Suite and iteratively optimized to meet the performance requirements of next-generation wireless systems.
