Abstract:
With the rapid advancement of 5G networks, the demand for efficient, compact, and multi-functional smartphone antennas has increased significantly. This paper presents the design and analysis of a compact Four-Element, Four-Port mushroom-shaped MIMO antenna system optimized for sub-6 GHz 5G smartphone applications to address these requirements. The proposed antenna array utilizes mushroom structures and Defected Ground Structures (DGS) to enhance polarization diversity, improve isolation, and suppress mutual coupling without complex decoupling networks. Designed on an FR-4 substrate with miniaturized radiators, the antenna system is optimized for space-constrained smartphone platforms, offering full radiation coverage and multiple resonance points. Simulated results demonstrate efficient radiation patterns, low reflection coefficients (below -10 dB), and excellent MIMO performance, with low Envelope Correlation Coefficients (ECC) below 0.04 through the entire frequency band. The design is well-suited for future 5G devices, ensuring reliable performance and high spectral efficiency for multi-band, multi-port communication systems.
