Dielectric Resonators are being used as antennas in wireless communication systems presently due to advantages over microstrip like low loss particularly at higher frequencies. Also with ever increasing demand for bandwidth, wide banding has become one of the prime goals of antenna design. DRA wide banding can be done using stacking.

From optimization to dielectric resonator antenna (DRA) application of YIG: Synthesis approach
Journal of Alloys and Compounds, 2015Abstract The efficacy of yttrium iron garnet (YIG) as magneto-dielectric ceramic, depends heavily on its purity. The presence of undesirable phase(s) such as yttrium iron perovskite (YIP) has led to performance deterioration, which is critical especially in wireless communication devices. This work presents the use of an ANOVA-statistical approach to

Breast Cancer Detection with a Ring-Shaped DRA (Dielectric Resonator Antenna)
2019This paper presents simulation results of tumor detection by placing a phantom parallel to square ring-shaped DRA. This is based on the difference between malignant and normal breast tissues electrical properties. For this purpose, a square ring-shaped DRA with plus DGS in ground is designed. This has volumetric dimensions of 60 × 60 × 5.67 mm3.

Study on the Effect of Dielectric Structure to the Cylindrical Dielectric Resonator Antenna (DRA)
2014This paper presents the effect of variation of diameter and height of DR to the resonant frequency and radiation pattern of DRA. Analysis was carried out on the DR with diameter of 10.66 mm and height of 4.4 mm. The simulated and measured resonant frequencies were 3.67 and 3.77 GHz, respectively. The E-plane radiation pattern of CDRA was bi-directional

Journal of Materials Science: Materials in Electronics, 2014
YIG is useful for dielectric resonator antenna (DRA) but its narrow size of frequency bandwidth (0.38–0.44 GHz), negatively influenced the DRA performance. An investigation on Ce doped YIG through the conventional solid-state reaction based on the Y3−xCexFe5O12 (Cex; x = 0–1.5) system was carried out.
