“…4 Sani et al proposed wideband MIMO applications with a K-shaped microstrip line-fed cylindrical DRA. A Wideband feature has been achieved through metallic patch loading over the DR. 5 Similarly, isolation enhancement is another important area of research. There are multiple methods available in open literature such as the use of space diversity.…”

In this article, a modified layout of cylindrical dielectric material-based, resonator-type multiple input multiple output antenna (MIMO) is presented.The beam tilting feature is achieved by using a conducting plate placed in the mid of two antenna elements. Dual frequency-band operation, that is, 2.4-4.02 and 4.78-6.21 GHz is obtained by sourcing the ring DRA electromagnetically with asymmetric S-shaped aperture via microstrip line. Dual CP waves are supported by the designed antenna within the operating frequency band, that is, 2.84-2.95 and 5.63-5.66 GHz. The two ports are placed in parallel. Some salient features of the designed antenna are (i) pattern diversity (θ = ±30 in XZ plane) is obtained between two parallel placed ports by applying conducting plate; (ii) polarization diversity is obtained by simply taking a mirror image of the proposed aperture. The most favorable value of diversity parameters of the suggested DR-based MIMO antenna makes it satisfactory for smart transport and vehicular communication applications in the sub-6-GHz range.
