“…This is mainly attributed to the fact that DRAs do not suffer from conduction losses and characterize by high radiation efficiency, when the feed is excited properly. For bringing a new horizon, an overview of basic shapes DRAs and a complete state‐of‐the‐art for mm‐wave DRAs are presented, as a comparative focus. Then, a working methodology in the form of design, simulation, and analysis of basic shaped DRAs at 60 GHz mm‐wave frequency band are reported.…”

This review article provides an extensive literature survey on the research progress of dielectric resonator antenna (DRA) at millimeter‐wave frequency band that includes concepts of DRAs, their empirical formulae and design methodologies for different shaped DRAs at 60 GHz frequency band. The different shaped DRAs such as cylindrical, rectangular, hexagonal, and octagonal at 60 GHz are designed, simulated and analyzed using CST microwave studio solver. The −10 dB impedance bandwidth of cylindrical, rectangular, hexagonal, and octagonal DRAs are 52.7 to 62.8 GHz, 57 to 62.2 GHz, 55.8 to 64.2 GHz, and 54.2 to 63.5 GHz, respectively. The idea behind getting broad impedance bandwidth is due to use of double‐layer substrate with different permittivity (εr1 = 4 and εr2 = 11.9). Empirical formulae are deduced for hexagonal and octagonal DRA, by studying the analogy of dielectric resonator geometry. Consequently, the mode of different shaped DRAs, that is, HEM111 and TE111 are investigated by the electric field and magnetic field distribution. With these analysis, a comprehensive research review over the period of the last two decades is carried for investigating various techniques, targeted to realized gain, circular polarization, and impedance bandwidth. Along with these analysis the state‐of‐the‐art at different shaped DRAs at mm‐wave frequency band are also reported.

A higher mode-based dielectric resonator antenna (DRA) featuring attractive characteristics has been explored and successfully demonstrated for use in wireless industry. In here, an improvised elevated feed platform has been conceived to exploit HEM 12δ mode in a cylindrical DRA. An additional filtering mechanism by a selective loading has been introduced to achieve a clean and exclusive HEM 12δ resonance. A single unit has been characterized at C-band based on the available characterization facility and experimentally verified ensuring 22% wide matching bandwidth with as much as 11 dBi peak gain. A practical 2 × 2 array with a corporate feed has been successfully demonstrated. A consistent radiation pattern over about 10% matching bandwidth has been experimentally demonstrated. This ensures a flat peak gain (13-14 dBi) over the full usable frequency band. This is novel in terms of its pure higher mode operation supporting a wireless system with uniform gain characteristics. Its improved features compared to the earlier designs have been clearly discussed.

“…The shrinking effect of the LTCC substrates makes it more challenging and expensive in terms of its fabrication process. In [12], a monolithic polymerbased high gain Dielectric Resonator Antenna (DRA) was implemented efficiently. In [13] a wideband magneto electric dipole antenna was designed, despite the high bandwidth…”
