Abstract

This letter presents a compact six-port multiple-input-multiple-output (MIMO) antenna system with three antenna modules, each arranged in divergent directions for optimal spatial reuse, polarization diversity, and isolation enhancement. Decoupling components are incorporated to achieve shared-aperture decoupling. Measured results show isolation exceeding 11.5 dB between ports, a −6 dB bandwidth covering 3.4 GHz to 3.6 GHz, and radiation efficiency above 50% per port. The proposed design improves spatial reuse and integration for mobile applications, making it a promising solution for next-generation MIMO communications.
