This survey article outlines a comprehensive investigation of research carried out on dielectric resonator antennas (DRAs) in the last three and half decades, in an application‐oriented approach. DRAs have created a remarkable position in antenna engineering for their adept characteristics like high efficiency, low loss, wide bandwidth, compact size, 3‐dimensional modeling flexibility, etc. The use of DRAs for different commercial and defense applications associated with the wireless communication is highlighted in this article. To make a smooth and effective survey article, all the application‐oriented DRAs available in the open literature are classified in five different categories like microwave bands, specific frequency, technology, millimeter‐wave, and miscellaneous types. The ultimate aims of this review article are as follows: (i) highlights the usability of DRAs for different commercial and defense applications, (ii) helpful for the antenna industries/manufacturers to find out the best DRA for any specific application as per their requirement, and (iii) points out research gap in some application domains which will be quite helpful for future antenna researchers. In the authors' opinion, this survey may be helpful to DRA researchers as such a survey process is not available in the open literature.

“…In recent years, several advanced techniques are developed to solve the DRA's fabrication and positioning issue in an array, making it more competitive in future wireless communication systems. Some efforts have been done on the design of wideband DRAs . In Reference , the reported DRA can achieve a bandwidth of 35% by using stacking technology, but the DRs' sizes need to be different.…”

“…In Reference , the DRA with two operating modes, characterized by a lattice structure, exhibits a wide impedance bandwidth of 39%. Meanwhile, some special‐shaped DRAs such as T‐shaped DRAs in Reference , E‐shaped DRAs in Reference , and A‐shaped DRAs in Reference , can provide very wide bandwidths by exciting several adjacent resonances. For instance, the T‐shaped DRA can obtain an impedance bandwidth of 75.1% .…”

A wideband stacked dielectric resonator antenna with stable patterns is proposed for fifth‐generation of mobile technology in this paper. With the help of inserted air gaps to reduce the radiation Q factor, the stacked structure with two thin high permittivity sheets and two hollow low permittivity slabs can provide four adjacent resonant modes to form a wide bandwidth. Measured results demonstrate that the antenna obtains an impedance bandwidth of 54% for |S11| < −10 dB and a peak gain of 9.2 dBi. The radiation patterns remain stable and symmetrical over the entire operating band.

“…The designs of compact UWB antennas are very important aspect in the progress of UWB technology, which impose the constraints of low cost and embedding of antennas into the wireless devices and RF circuits. The dielectric resonator antenna (DRA) is obviously a good choice for such applications because of its several advantages, such as compact size, higher power handling capacity, radiation efficiency, considerable bandwidth, light weight, and the most important feature of DR is that it does not have any conductor and surface wave losses. Moreover, the electromagnetic coupling between the microstrip feed and the DRA improves the bandwidth (impedance) considerably.…”

This article presents the experimental study of a ultra‐wideband (UWB) active antenna comprising of a chaotic oscillator coupled to a dielectric resonator antenna. Wideband spectrum properties of chaotic signals are used to design an UWB active antenna. In contrast to classical active UWB antenna designed using patch, the proposed active antenna is capable of enhancing the bandwidth, easy to integrate with the oscillator and is small in size. The proposed UWB antenna using DR can be employed in UWB wireless communication systems.
