Abstract

The structural properties of the Ba(1−x)Dy(2x/3)ZrO3 system were investigated by means of XRD, FT-Raman, and FTIR spectroscopy. XRD analysis exhibited that lattice parameter gradually decreased with increase of Dy content. FT-Raman and FTIR analyses showed that with increase of Dy content more ordered structure was formed in the composition. The surface morphology of sintered pellets was studied by the SEM. The microwave dielectric constant and quality factor were investigated by the method as proposed by Hakki–Coleman. The microwave dielectric constants of sintered pellets were found to be decreased from 38.40 to 21.13, and the value of τf changed from 384.71 to 62.71 ppm/°C. The Q × f values changed from 5731 to 5173 in the composition between x = 0.0 and 0.1. The dielectric resonator antenna (DRA) was investigated experimentally and numerically, using a monopole antenna through an infiniteground plane and Ansoft’s high-frequency structure simulator software, respectively. The required resonance frequency and bandwidth of DRA were investigated in the composition between 0 ≤ x ≤ 0.1.
