Two-element MIMO Antenna with High isolation based on Zigzag-shaped Slot on the ground for 5G and IOT applications

This paper proposed the two port antenna with zigzag-shaped slot decoupling structure and high isolation for 5G and IoT applications. The microstrip-fed radiator is accomplished to design the two-port MIMO element antenna where the ground decoupling structure between antenna elements improves the ground length and matching of the antenna. The Zigzag-shaped slot is introduced on in the ground which improves the isolation and diminishes the surface current between antenna elements. The operating bandwidth achieved from 4 GHz to 5.1 GHz with |S21|> 24 dB isolation where the maximum isolation is obtained up to 37dB. The two-port MIMO antenna covers the radar altimeter (4.2 GHz to 4.4 GHz), 5G (n79 - 4.4 GHz to 5 GHz), and 5 GHz IOT/Wi-Fi applications.
