Summary:This work introduces a Multiple-Input Multiple-Output (MIMO) patch antenna operating from 5.84 to 6.01 GHz for Vehicle-to-everything (V2X) communication. The proposed MIMO antenna is fabricated on low cost FR4 substrate with compact dimensions of 1.17λo×1.17λo×0.03λo (λo is the wavelength at the smallest operating frequency). The study highlights the importance of MIMO technology in V2X communication. The antenna elements are placed orthogonally to improve the isolation. The mutual coupling is further reduced by employing the Defected Ground Structure (DGS) consisting of circular rings and swastika-shaped rectangular slits. The presented MIMO antenna has diverse radiation pattern characteristics ensuring the maximum coverage area with high radiation intensity. The maximum Envelope Correlation Coefficient (ECC) of 0.02 is obtained in the operating frequency range. Other MIMO parameters are also calculated and verified. The suggested antenna exhibits a peak realized gain of 6.3 dBi. These results strongly imply that the proposed antenna is suitable for the V2X communications.
