A New Compact Dual-Polarized MIMO Antenna Using Slot and Parasitic Element Decoupling for 5G and WLAN Applications

This paper presents a compact dual-polarized multiple-input multiple-output (MIMO) antenna for fifth generation (5G) and wireless local area network (WLAN) applications. At first, two-element MIMO designed to operate at 3.5 GHz was developed. After that, some modifications were performed in the initial configuration, 5.35 GHz. A simple decoupling technique using parasitic element slot used enhance isolation between radiating elements achieve an above 18 dB over band ranging from 3.4 3.6 first antenna, isolations 19.8 16.75 second 5.15 5.85 antenna. Simulations Ansoft HFSS software numerical characterization prototype fabricated with FR-4 dielectric measured, presenting good agreement simulated measured results. Furthermore, envelope correlation coefficient (ECC) diversity gain (DG) analyzed present
