Compositionally induced phase transitions in the system Sr(Zr x Ti 1−x )O 3 were analyzed using a combination of X-ray diffraction, FT-Raman and FTIR spectroscopy. Sr(Zr x Ti 1−x )O 3 system showed at least two tilting of phase transitions, pm3m–I4mcm and I4/mcm–pnma. The structural transition occurred due to tilting of BO 6 octahedra. Dielectric constant measured with Hakki–Coleman technique decreased from 253 to 25 with increase of Zr content. The value of τ f found 1771ppm/°C for SrTiO 3 which decreased to −82ppm/°C for the SrZrO 3 . The dielectric resonator antenna (DRA) was investigated experimentally and numerically using a monopole antenna through an infinite ground 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≤1.0.
