“…To further enhance directivity, researchers have employed a superstrate structure over the DRA, achieving a gain of 17.8 dBi in the V band and 18.4 dBi in the W band. However, it is important to note that the introduction of a superstrate or lens may also increase the on-chip footprint size [ 45 , 46 ].…”

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.

“…The PRS-antenna configuration increases the peak broadside gain of the patch antenna by 12 dB, from 6.5 to 18.5 dBi 17 and the high-gain antenna for 60 GHz wireless networks fed by an microstrip with PRS has a maximum experimental gain of 16.4 dBi 18 ; The simulated total efficiency of the antenna which consists of a single-layer dielectric superstrate and an aperture type feed is greater than 88% over the entire operating band (55.2-65 GHz) 19 ; A 16-way 34 GHz low-profile RCA is fed by multiple spherical DRs demonstrates high overall efficiency of 80%. 20 In addition, the first work on the integration of EBG technology with chip-based antennas results in a high-gain, low-profile system with high radiation efficiency as well as high aperture efficiency. 21 Inspired by the above researches, a dual-band resonator is introduced into the mm-wave antenna design and low-gain fed source antenna.…”

A high-gain dual-band electromagnetic band-gap (EBG) resonator antenna (ERA) which is suitable for 60 GHz short-range communication and 77 GHz vehicle collision avoidance application is proposed. The EBG is constructed by two identical slabs over a fully reflective ground plane. A dipole in Taiwan Semiconductor Manufacturing Company (TSMC) 65 nm process is employed to serve as a feeder of the resonator. By combining the frequency resonances of the EBG and the feeding chip fabricated on the LTCC substrate, the proposed ERA obtains dual-band performance. Furthermore, the proposed ERA achieves a high gain by designing two slabs to have phase shifts introduced by multiple reflections of the wave between the ground and slabs at double certain frequency points. Finally, the prototype of the antenna is simulated by High Frequency Structure Simulator (HFSS) and good agreement was achieved between simulated and measured data. The results demonstrate that it has a 10-dB return loss bandwidth of 57.7 to 62.1 GHz and 75.2 to 77.4 GHz. Radiation efficiencies are 27.5% and 60% with 8.3 dBi gain and 14.4 dBi gain at 60 and 77 GHz, respectively.

“…Since the additional functionality considered in this paper, power combining/dividing, is reciprocal, the term combiner is used instead of combiner/divider for the rest of the article. Implementation of on-antenna power combination architectures implemented with cavities [2]- [4], patches [5] - [7], slots [8] - [10] and loops [11] - [16] have been previously reported. However, these single-frequency resonant struc- tures fail to provide a reasonable bandwidth for the combiner action.…”

This article presents a quasi-self-complementary radiator structure designed to operate simultaneously as a combiner and an antenna. The dual-port architecture comprises axially symmetric nested microstrip loops. The upper half of the radiator structure placed on the top plane is nearly complementary to the lower half on the bottom plane. The nested loop is loaded with a Yagi element for improved performance. This additional element in the radiator enhances the end-fire radiation from the nested loop wideband dual port structure without disturbing the parallel combiner action. An additional gain of nearly 3 dB is obtained with this element across the operating bandwidth. Measurement of both the fabricated prototypes, with and without the Yagi element, reveal the desired parallel combiner action for an operating range of 1.8 -2.3 GHz with good matching. The quasi-self-complementary nested loop architecture offers a wide operational bandwidth. The proposed radiator structure is a compact and low-loss alternative for antenna arrays.
