A novel multiple-input multiple-output double asymmetrical cylindrical dielectric resonator antenna (MIMO-DCDRA) with modified stub line feed is discussed and proposed in this work. Two unequal CDRA are placed diagonally to each other and are electromagnetically coupled with feeding arrangement via two asymmetrical circular apertures. By performing the optimization of the dimensional parameters, a significant impedance bandwidth of 70.84% ranging from 2.87 to 5.76 GHz and axial ratio bandwidth (ARBW) of 34.89% is obtained. Antenna gain is about 5.0 dBi within the operating frequency. The proposed MIMO-DCDRA exhibits a low mutual coupling of (jS 21 j & jS 12 j < À20 dB) with the incorporation of a neutralization line. There are various diversity parameters that are also discussed in terms of mutual coupling, envelop correlation coefficient (ECC < 0.002), diversity gain (DG > 9.995), and channel capacity loss (CCL < 0.3 bits/s/Hz) over the entire impedance bandwidth.

“…High speed wireless data transfer became possible because of advent of multiple input multiple output (MIMO) technology. Different configurations of MIMO DRA are presented in recent times [10][11][12][13][14][15][16]. In [10] authors reviewed recent MIMO DRAs with various perspective and concluded that multi-port MIMO DRA are tough to design owing to problems associated with them.…”

In modern communication systems, dielectric resonator antennas (DRA) play an important role due to its several advantages over contemporary antennas. In this paper, novel flower-shaped multiple input multiple output (MIMO) DRA is proposed for wireless applications in X- band. The proposed antenna with four ports displays more than -15 dB isolation between ports with defected ground technique. The antenna exhibits 7.2-7.5 GHZ impedance bandwidth and 4.66 dBi gain at 7.3 GHz. MIMO performance parameters: Envelope Correlation Coefficient (ECC) and Diversity Gain (DG) of the proposed antenna are also studied and calculated.

In this article, a dual‐band circularly polarized multiple‐input‐multiple‐output (MIMO) dielectric resonator antenna (DRA) is proposed for 3.5 and 5.5 GHz bands, both being located under 6 GHz. Known as sub‐6 (or as mid‐band), they provide good coverage and capacity in the newly targeted fifth‐generation (5G) systems. The proposed structure consists of two ring DRAs (RDRAs) etched on a 0.8 mm thick RT Duroid substrate. Measured impedance bandwidths in broadside direction are 3.1‐3.75 GHz (19%) and 5.3‐5.6 GHz (9.4%) and circular polarization (CP) bandwidths are 3.425‐3.6 GHz (5%) and 5.45‐5.55 GHz (2%), respectively. CP is achieved by exciting HE modes using two probes placed orthogonaly to each other, that is, at an azimuthal angular distance of 90∘. Varying the lengths of the probe allows achieving the necessary time‐phase quadrature between modes. Comparison between recent multiband circularly polarized MIMO DRAs and proposed prototype has revealed that CP bandwidth in both bands is one of the highlighting advantages of the present configuration.
