We review dielectric resonator antenna (DRA) designs. This review examines recent advancements across several categories, specifically focusing on their applicability in array configurations for millimeter-wave (mmW) bands, particularly in the context of 5G and beyond 5G applications. Notably, the off-chip DRA designs, including in-substrate and compact DRAs, have gained prominence in recent years. This surge in popularity can be attributed to the rapid development of cost-effective multilayer laminate manufacturing techniques, such as printed circuit boards (PCBs) and low-temperature co-fired ceramic (LTCC). Furthermore, there is a growing demand for DRAs with beam-steering, dual-band functions, and on-chip alignment availability, as they offer versatile alternatives to traditional lossy printed antennas. DRAs exhibit distinct advantages of lower conductive losses and greater flexibility in shapes and materials. We discuss and compare the performances of different DRA designs, considering their material usage, manufacturing feasibility, overall performance, and applications. By exploring the pros and cons of these diverse DRA designs, this review provides valuable insights for researchers in the field.

“…A DRA is a resonator antenna composed of nonmetallic dielectric materials with a high dielectric constant. The interface between dielectric materials and air can be equivalent to an electric wall or a magnetic wall, which composes the electromagnetic resonance domain 8,9 . The bandwidth of a DRA can be expanded by exciting multiple resonant modes with adjacent frequencies based on a reasonable method 10,11 .…”

A novel wideband cube resonator antenna (CRA) composed of metasurfaces is proposed in this letter, which can be applied to an active integrated antenna system. The resonant region of the CRA is formed by six metasurfaces of 4 × 4 arrays. The six surfaces can be equivalent to ideal electric walls. With the improved feeding slot, the dominant mode TE1δ1 and high‐order mode TE1δ3 are effectively excited, which enables a wideband and high gain performance for the CRA. A prototype of the antenna is fabricated and measured to verify the antenna design principle. The antenna has a measured impedance bandwidth of 17.0% (4.42–5.24 GHz) and a peak gain of 8.51 dBi, and good agreement between the simulated results and measured results is obtained. The proposed CRA shows resonant mode and radiation performance similar to those of traditional dielectric resonator antennas, which provides a new technique for the design of resonator cavity antennas.

“…For this reason, a solution is needed to increase the isolation between elements [14,15]. Several studies to improve the isolation of massive MIMO antennas have been proposed previously, such as the development of a dielectric resonator antenna (DRA) [16][17][18][19][20][21], using a frequency selective surface wall [22,23], using parasitic elements [24], using an antenna filtering method [25], and adding stacked patch antenna design [7]. Besides, it is also proposed a combination of dielectric resonator design with shielded metasurface [26], fractal design techniques to increase radiation efficiency [27][28][29][30], and decoupling technique to improve isolation between elements to improve antenna performance [31][32][33][34][35].…”

High isolation between massive MIMO antenna elements is one of the important parameters that improves antenna performance, especially for 5G communication applications. In this study, we propose a design to improve isolation between elements to enhance the antenna performance. The proposed solution to improve the performance of massive MIMO antennas is to use a combination of dielectric resonator, electromagnetic bandgap (EBG) and defected ground structure (DGS) techniques at the frequency band 3.5 GHz as the 5G frequency band under 6 GHz. The material used is FR-4 which has a dielectric constant ($${\varepsilon }_{r}$$ ε r ) of 4.3. Simulation results and measurements between antenna elements show an improvement in mutual coupling, widening the bandwidth and increasing the gain of the antenna. The proposed design using the dielectric resonator antenna (DRA) by MIMO 8 × 8 16 port—64 elements and the addition of EBG and DGS structures on the ground plane—has shown to suppress mutual coupling parameter lower than without using DRA-EBG-DGS design by 15 dB, increase bandwidth to 246 MHz, increase gain to 24.7 dB and improve the overall envelope correlation coefficient (ECC) parameter.
