A Self-Decoupled MIMO Patch Antenna System for V2X Communications
This article presents a new method for self-decoupling in multiple-input-multiple-output (MIMO) circular patch antenna (CPA) system. In the presented method, three shorting vias are strategically placed in the E-plane of the probe-fed CPA resonating in TM11 mode to create a weak-current density region on the ground plane where the adjacent antenna element can be placed. Initially, a two-element MIMO antenna system is designed, developed, and tested for vehicle-to-everything (V2X) communication in the IEEE 802.11p band. High inter-port isolation of 78 dB across the entire 5.82 to 5.98 GHz operating band is obtained. Both antenna pairs exhibit identical radiation properties, with a peak gain of 7.4 dBi. Furthermore, a 10-element MIMO antenna system is developed, showing promising results for V2X MIMO communications.
