“…An air gap was introduced in the middle section to obtain this enhanced bandwidth and a peak gain of 5–7 dBi was also achieved with this design [115]. Generation of higher-order modes and merging of modes technique was adopted to achieve a bandwidth of 8.2 GHz with a gain of 9 dBi using the dual excitation method for RDRA in the same year [116]. A 124.4% impedance bandwidth was reported in a work where a cylindrical DRA was fed by a rounded bevel-shaped patch.…”

Dielectric resonator antennas (DRAs) are developed antennas that are lightweight, wideband, small-sized and have high radiation efficiency. A DRA is an appropriate candidate for any radio communication including radar applications mainly because of its high efficiency and wideband performance. As the development of DRAs has been a continuous process for more than five decades the plethora of the same has become magnificent in all possible ways. Scientists have walked the technical path for more than centuries and tried to meet the various challenges in the most graceful ways. Reduction of loss, lightweight, and desired radiation patterns are some of the issues which are effectively met by DRAs. This paper presents a brief comprehensive review of the state of art techniques, giving an exhaustive idea of achieving broadband and multi-frequency operations in the areas of DRAs. The paper associates the references of the past and correlates with the current and future trends of research in DRAs that could be of immense help to the young upcoming researchers interested in this field.
