In this paper, a moon-shaped aperture-coupled ring-shaped dielectric resonator antenna (DRA) is suggested, realized, and tested. The L-shaped microstrip line is designed to stimulate the aperture. Vital characteristics of the proposed radiator are as follows: (a) Broadband DRA with dual-frequency circular polarized (CP) response is realized by the mixture of HEM X 11δ and HEM Y 11δ mode inring DRA; (b) wide impedance bandwidth is attained with the help of dropping the effective permittivity of radiating structure by converting cylindrical shape into a ring shape. To test the practical feasibility, the proposed antenna design is fabricated and tested inside the anechoic chamber. Practical outcomes confirm that the proposed antenna works over the frequency range of 2.44-3.66 GHz along with supporting dual CP waves within the operating range, i.e., 2.44-2.64 and 3.4-3.65 GHz respectively. Broadsided (θ = 0 0 and ϕ = 0 0 ) RHCP radiation pattern makes the proposed antenna design applicable for IEEE 802.15.4 wireless sensor network (2.5 GHz) and WiMAX (3.5 GHz).

“…On the other hand, CP was achieving by [12], using an antenna consisting of a D-shaped patch and a modified ground plane, which covered spanning WLAN and WiMAX frequency bands. Also, [13,14] are proposed a dual-band two-element and four-element CP dielectric resonator-based MIMO antenna, respectively, which achieve a good value of diversity parameters. Also, [15] proposed a four-element MIMO antenna system, each with a dual-polarized port, to enhance bandwidth and mutual coupling with a smaller size and work in a C-band frequency that is a promising 5G smartphone application band.…”

Using a circularly polarized antenna is an attractive method for balancing polarization to transmit and receive the antenna. Therefore, this paper explores a wideband 4-port CP multiple-input multiple-output (MIMO) antenna to be used for 5G wireless technologies in the sub-6 GHz range (3.5-5.9) GHz. Also, the polarization diversity between the neighboring radiators is used to achieve high isolation between antenna components, resulting in a low envelope correlation coefficient (ECC). Other MIMO efficiency metrics are analyzed, such as the proposed structure's Diversity Gain (DG), Mean Effective Gain (MEG), and Channel Capacity Loss (CCL). The finding shows that the suggested design's suitability can be considered a possibility for imminent sub-6 5G MIMO applications.

In this article, Dual port excitation spiral shaped dielectric resonator multiple input multiple output (MIMO) antenna is explored for wideband application. Dual coaxial feeding in inner and outer edge of spiral geometry generates orthogonal hybrid modes. Merging of various hybrid modes lead to a wide bandwidth of operation. HE11δx, HE11δy and HE12δx, HE12δy0.25em orthogonal radiating modes are investigated at 8.7 GHz and 11 GHz resonant frequencies, respectively. Proposed antenna covers wide operating frequency range from 8–15.1 GHz to 7.8–14.6 GHz corresponding to excitation of Port‐1 and Port‐2, respectively, is achieved between ports. Isolation below −25 dB. Envelope correlation coefficient, diversity gain, Total active reflection coefficient, radiation pattern, channel capacity loss, gain, efficiency and various other characteristics of MIMO antenna are explored. This antenna can be used for various C and X band wireless applications.
