“…Broadly, these approaches can be divided into four categories; firstly, according to the antenna geometry (DR shape/fractal/EBG/metamaterial), secondly, the coupling mechanism (feeding type/aperture shape), thirdly, the DR permittivity, and lastly, according to the excitation of specific mode. From ease of readers' point of view, these techniques are discussed separately for single‐band, dual‐band, and multi‐band,, respectively. Moreover, some other characteristics say radiation/notch…”

“…Next to DRA shape, the coupling mechanism plays an important role in controlling performance characteristics of DRA. This technique is also known as bandwidth improvement by means of impedance matching and this can be established either by modification in feeding line or slot types …”

“…Weng et al, have used the air dielectric between the rectangular DR and the ground plane for enhancing the bandwidth up to 61%. Deng et al, have introduced a pair of symmetrical edge resonators to antenna, where each resonator is composed of a T‐shaped slot etched on the edge of the radiator and a strip printed on the opposite side of the substrate along with U‐slot DFS concept to achieve dual band of 2.4 to 2.48 GHz for Bluetooth and 3.1 to 10.6 GHz for UWB frequency bands. Rahimian et al, have used branch line coupler to excite a rectangular DRA for operating over more than 90% impedance bandwidth.…”

This article shows a compressed chronological overview of dielectric resonator antennas (DRAs) emphasizing the developments targeting to bandwidth performance characteristics in last three and half decades. The research articles available in open literature give strong information about the innovation and rapid developments of DRAs since 1980s. The sole intention of this review article is to, (a) highlight the novel researchers and to analyze their effective and innovative research carried out on DRA for the furtherance of its performance in terms of only bandwidth and bandwidth with other characteristics, (b) give a practical prediction of future of DRA as per the past and current state-of-art condition, and (c) provide a conceptual support to the antenna modelers for further innovations as well as miniaturization of the existing ones. In addition some of the significant observations made during the review can be noted as follows; (a) hybrid shape DRAs with Sierpinski and Minkowski fractal DRAs seems comfortable in obtaining wideband as well as multiband, (b) combination of multiple resonant modes (preferably lower modes) can lead to wider impedance bandwidth, (c) at proper matching wider patch with slotted dielectric resonator can exhibit better bandwidth.

“…In these proposed monopole antennas, a large solid ground plane having the shape of a square, rectangle, circle, or ellipse is usually adopted. Different from these antennas, a novel ground structure named DGS has recently been investigated and found to be a simple and effective method to reduce the antenna size as well as excite additional resonance modes [11][12][13][14][15].…”

A novel triple-band microstrip-fed planar monopole antenna with defected ground structure (DGS) is proposed for WLAN and WiMAX applications. The proposed microstrip-fed antenna consists of a rectangular patch, dual inverted L-shaped strips and a defected ground. The designed antenna can generate three separate resonances to cover both the 2.4/5.2 GHz WLAN bands and the 3.5 GHz WiMAX bands while maintaining a small overall size of 20 mm × 27 mm. A prototype is experimentally tested, and experimental results show that the antenna gives good radiation patterns and enough antenna gains over the operating bands.
