“…These co-fabrication methods are illustrated in Figure 2: (1) manufacture the DRAs and feed jointly in one substrate (see Figure 2a); (2) connect each DRA element with dielectric bridges so that the array becomes one connected body, as shown in Figure 2b; (3) mount each DRA element in a low-permittivity template to enhance the alignment accuracy with the feeding network, as depicted in Figure 2c; (4) substrate-integrated DRAs in metal cavities (SIDRAs) with drilled vias or dielectric-filled vias to excite the desired DR modes (see Figure 2d); and (5) SIDRAs realized in substrate-integrated gap waveguide (SIGW) technology, where the feeding network closely affects the DRA modes (see Figure 2e). Recent microwave and mmW compact DRA and DRA array designs based on the above methods are cross-compared in [17][18][19][20]; (c) in-template DRA [21,22]; (d) substrate-integrated DRA (SIDRA) [23][24][25][26][27][28][29];…”

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.

“…These techniques not only reduce the size of the antenna but also make DRA a successful antenna at mm-wave frequencies. A unique design is recently proposed in [93] where a compact and broad CP DRA using dielectric vias is designed. Filling a perforated printed circuit board (PCB) substrate with barium strontium titanate with a dielectric constant of 20 creates the dielectric vias.…”

Dielectric resonator antennas (DRA) are advantageous due to their small size, high radiation efficiency, ease of excitation, and minimal metallic losses. Enhancing the gain of DRA will make them suitable for a variety of applications such as wireless communication technology. High-gain antennas are required for wireless communication to overcome the difficulties of high path loss. The researchers have presented numerous techniques, including stacked DRA, DRA array, and higher-order mode excitation for enhancing the gain. This article provides a comprehensive summary of the state of art techniques and geometries including stacking, frequency-selective surfaces superstrate, electromagnetic band gap structures, hybrid techniques, arrays, etc., for increasing DRA gain. Techniques to improve other parameters like bandwidth and radiation efficiency along with gain are also discussed. The challenges in each technique and the possible applications are presented. Based on the studies, it is observed that the DRA array technique is suitable for obtaining gains up to 19 dBi for radar-based applications. For low-profile DRA requirements, hybrid DRAs prove prolific in enhancing gain up to 16 dBi.

“…The DR antenna (DRA) is a good choice for many microwave and millimeter wave applications due to its unique features such as low losses, high impedance bandwidth, compact structure, and ease of excitation. [1][2][3][4][5] Many wireless applications today require a wide beamwidth antenna, for example in satellite communications, to ensure stable communication with the terrestrial receiver, the terrestrial receiver antenna pattern is required to cover the entire upper half space. [6][7][8][9][10] In other applications such as military radar and target tracking systems and automotive radar, wide beamwidth antennas are needed.…”

A new method for beam widening of rectangular dielectric resonator antenna has been introduced by using anisotropic material inside its prism. It is proved that using this method, the radiation of the upper wall can be increased compared to the side walls of the antenna, which in turn leads to an increase in the beam width of the antenna. The antenna consists of two different dielectric layers that are placed alternately in the horizontal direction. The thickness of each of these substrates is small compared to the wavelength. Therefore, the resulting overall structure behaves like an anisotropic medium. A sample of the antenna is fabricated and measured. A good agreement between the simulated and measured results is attained.dielectric resonator antenna (DRA), gain, half power beam width, impedance bandwidth
