Abstract: The rapid adoption of fifth-generation (5G) wireless technology has intensified the demand for compact, efficient, and high-performance MIMO antenna arrays in electronic devices such as smartphones and tablets. While MIMO technology is central to achieving enhanced spectral efficiency, high data rates, and reliable connectivity, its integration into limited device footprints remains constrained by challenges including mutual coupling, impedance mismatch, and reduced radiation efficiency. This study investigates the performance optimization of 5G-enabled electronic devices by designing and implementing novel MIMO antenna arrays with defected ground structures, neutralization lines, and engineered array geometries. Using both simulation and experimental methods, the study evaluates key performance metrics including gain, bandwidth, isolation, efficiency, and envelope correlation coefficient across sub-6 GHz (3.5 GHz) and mmWave (28 GHz) bands. The optimized designs demonstrate significant improvements over baseline models, achieving up to 2.6 dB higher gain, broader impedance bandwidth, and isolation values exceeding −20 dB, while reducing correlation coefficients below 0.1. These enhancements validate the effectiveness of structural innovation over miniaturization alone in addressing the constraints of compact device integration. The results indicate that such optimizations not only improve channel capacity and energy efficiency but also ensure robust performance under real-world usage scenarios, thereby aligning with the critical key performance indicators of 5G systems. The study concludes that integrating advanced isolation and decoupling techniques provides a practical pathway for the commercial realization of reliable, high-capacity, and user-friendly 5G-enabled electronic devices.
