“…1. The b-DRA shape appears similar to that of the notched rectangular DRA of [8]. However, two crucial differences can be identified: First the b-DRA is constructed from a high-dielectric-permittivity material, and second, it uses only thin material plates, resulting in notch dimensions larger than for the notched DRA.…”

“…The strong relation between the dielectric resonator geometry (shape and materials) and its operational properties has been extensively demonstrated in the literature [3]- [8]. For example, an inversed trapezoidal DRA and an inversed pyramidal DRA were presented in [3] and [4], respectively, demonstrating a wide impedance bandwidth and well-behaved broadside radiation patterns.…”

“…Furthermore, various multilayer DRAs in rectangular [6] and cylindrical [7] configurations have demonstrated that the combination of different materials can be exploited to enhance the bandwidth of DRA operation. Finally, a notched rectangular DRA demonstrating a 28% wide bandwidth and broadside patterns was investigated in [8]. This DRA comprised an aperture-fed rectangular parallelepiped whose central part had been removed.…”

Abstract-Different configurations of bridge-shaped dielectric resonator antennas (b-DRAs) made of high-permittivity materials are presented in this letter. These DRA geometries can be seen as an evolution of the notched rectangular DRAs introduced by other authors, but their operational principle is different. The particularities and advantages of the proposed geometry will be investigated and demonstrated for a single bridge first. Afterward, the concept will be extended to two realizations of well-operating dual-mode b-DRAs with stable radiation patterns and low cross polarization. For the analysis of these structures, a full-wave analysis solver (HFSS) was used. Prototype fabrication and measurements confirm the results of the simulations.

“…Some feeding structures [5,8] can also be used to obtain a wide-band DRA. The second approach is to use more than one dielectric resonator (DR) element [4][5][6][7][8][9], which is often called as a "stacked" DRA, with different sizes of different dielectric materials.…”

Abstract-In this paper, a novel nine elements array dielectric resonator antenna (DRA) is presented. The DRA was excited by a microstrip feeder with a rectangular aperture coupled slots. The slot positions were determined based on the characteristic of standing wave ratio over a short ended microstrip. The measured gain of the array DRA operating at 5.84 GHz was about 10 dBi having impedance bandwidth of 60 MHz. The proposed DRA exhibits an enhancement of the gain in comparison with a single pellet DRA. The size of the whole antenna structure is about 60 mm × 40 mm and potentially can be used in wireless systems.

In this article, a hybrid two segments ring dielectric resonator antenna with partial ground plane, for ultrawideband application is described. The proposed antenna structure consists of annular shape microstrip line along with two ring dielectric resonators having different permittivity. By applying the combination of shifted annular shape microstrip line (used as a radiator as well as to convert TM01δ mode to TE01δ mode) and two segments ring dielectric resonator, ultra wide bandwidth has been achieved. Prototype of proposed structure has been fabricated and tested. Measured results show good agreement with the simulated ones. The proposed antenna structure operates over a frequency range of 3.45‐10.9 GHz with a fractional bandwidth of 103.83% and having better gain and radiation characteristics. © 2015 Wiley Periodicals, Inc.
