“…The band-rejection can be achieved by implementing slots of certain lengths in the radiating patch or the feed line [6,[15][16][17][18][19][20]. In this design, a rotated C-shape slot is etched in the radiating patch as shown in Figure 4.…”

<p class="Default">In this paper, a new approach to the design of an UWB monopole antenna with dual band-notched characteristics is presented. The antenna has the form of an elliptical monopole over a ground plane having an elliptical slot to achieve the UWB. The dual-band notch function is created by inserting a U-shaped and a C-shaped slots on the radiating patch, thus no extra size is needed. The proposed antenna shows a good omnidirectional radiation pattern across the band from 3.2 to more than 14 GHz. The dual band-rejection is for 4.88-5.79GHz centered at 5.4GHz and 7.21-8.46 GHz centered at 7.8 GHz. The antenna prototype using the FR-4 substrate with ε<sub>r</sub>=4.3 has a compact size of 25mm×25 mm ×1.45mm. The fabricated prototype showed experimental results comparable to those obtained from the simulations.</p>

“…Elmegri et al have designed a small DRA with T‐shaped feeding network operating between 3.1 GHz‐and‐5.5 GHz . A compact UWB DRA for 23% BW between 9.97 GHz‐and‐12.558 GHz with band notch centered at 10.57 GHz has also been designed . Abedian et al have proposed a novel UWB U‐shaped microstrip feed line excited DRA with more than 122% impedance bandwidth with avoiding interference problem for 3.22 GHz‐to‐4.06 GHz (WiMAX) and 4.84 GHz‐to‐5.96 GHz (WLAN) bands.…”

“…The maximum available literature have been categorized in four separate sections like; DRA for microwave band applications, specific frequency based DRA application, technology‐based DRA application, millimeter‐wave‐based DRA application, respectively. But some articles are still not covered in these sections and felt by the authors to be discussed in a separate section from their application, novelty, and importance point of view.…”

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.

“…The fractal structure offers wide impedance bandwidth which has been reported on rectangular, cylindrical and hemispherical DRAs [6,7]. Stacked DRA, dual-segment, hybrid DRA and slots in ground plane also well suited for improving the impedance bandwidth of DRA [8][9][10][11][12]. However, this makes the antenna bulky and less compact.…”

This paper presents a novel compact Koch snowflake fractal ring based Dielectric Resonator Antenna (DRA) for ultra wideband application. Firstly, Koch snowflake fractal geometry is implemented on the conventional Cylindrical Dielectric Resonator Antenna (CDRA). Further, the performance of the DRA is enhanced by fractal ring created on the snowflake geometry. With the application of the fractal and the fractal ring geometry, the Q-factor of DRA is reduced, thus the bandwidth of DRA is increased. The proposed antenna offers a wide impedance bandwidth of 90% ranging from 4.7 GHz-12.4 GHz. The effect of the fractal geometry enhances the gain of DRA. The proposed antenna achieves radiation efficiency more than 78%, throughout the bandwidth. Interestingly, the proposed configuration reduces the DRA volume by 76.63% with reduced volume of 7.91 cm 3. The experimental verification of the proposed structure shows good agreement between simulated and measured results.
