This work proposes a novel Multiple-Input Multiple-Output (MIMO) cylindrical dielectric resonator antenna (CDRA) incorporating a surface-mounted horn to enhance performance for 5.8 GHz Wireless Local Area Network (WLAN) applications. The integrated horn element substantially improves the realized gain, achieving 14 dBi, while maintaining high port-to-port isolation (> 20 dB) and a low envelope correlation coefficient (ECC), enabling robust diversity performance. The antenna employs a single cylindrical radiator excited by dual coaxial feeds, offering compact geometry and efficient MIMO operation. Comprehensive evaluations of channel capacity loss (CCL), mean effective gain (MEG), total active reflection coefficient (TARC), and diversity gain (DG) are conducted through full-wave simulations in HFSS and verified experimentally. An equivalent circuit model is also developed, demonstrating close agreement with electromagnetic simulations and measurements. The results confirm the proposed design’s potential for high-gain, high-isolation MIMO antennas in next-generation WLAN systems.
