“…When the dielectric constant of the DRA is equal to or more than 20, a high degree of coupling is realized because a high dielectric constant material will concentrate the field under the DRA. Thus, a high dielectric constant material is required at the bottom layer when the microstrip line is used to feed the structure [53]. Conversely, increasing substrate thickness will increase the spurious feed radiation and surface waves.…”

A comprehensive review on recent developments and applications of circularly polarized (CP) dielectric resonator antennas (DRAs) is proposed in this paper. DRAs have received more considerations in various applications due to their advantages such as wide bandwidth, high gain, high efficiency, low losses, and low profile. A broad justification for circular polarization and DRAs is stated at the beginning of the review. Various techniques such as single feed, dual, or multiple feeds used by different researchers for generating circular polarization in DRAs are briefly studied in this paper. Multiple-input-multiple-output (MIMO) CP DRAs, which can increase channel capacity, link reliability, and data rate, have also been analyzed. Additionally, innovative design solutions for broadening the circular polarization bandwidth and reducing mutual coupling are studied. Several applications of DRA are also discussed comprehensively. This paper finishes with concluding remarks.

The change of two cylindrical dielectric sections in an appropriate arrangement is used to improve the bandwidth of DRA . Several other techniques were challenged to increase the bandwidth of DRA such as changing the shape of the tetrahedral and the conical shape dielectric resonator .…”

In this article, we propose a conical dielectric resonator antenna with metamaterial operating in the C band and excited by a circular polarization. The circular polarization of the antenna is produced by an inclination of 45° on the two environments with a different dielectric constant of the slot excitation. The metamaterial is superimposed on the antenna by λr and thus allows to increase the gain of 3 dB in all the bandwidth. Simulation results are carried out using Ansoft's HFSS software. The parametric study of the antenna has been performed by varying the permittivity ɛ2 and the radius a2 in a first step and by adding the metamaterial in a second step. The obtained bandwidths of the conical dielectric resonator antenna without and with metamaterial are 1.14 GHz and 1.07 GHz, respectively, with a corresponding increase in gain of about 3 dB.
