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.

A low loss reflectarray element based on a dielectric resonator antenna (DRA) with a parasitic strip
2008 IEEE Antennas and Propagation Society International Symposium, 2008A strip-loaded DRA has been proposed as a promising reflectarray element in Ka-band. Varying the length of the strip enables one to adjust the phase of each DRA cell. A phase variation of 320deg and low loss (less than 0.6dB) are achieved at 30 GHz. This concept has been checked experimentally in C-band.

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.
