Microwave dielectric ceramics in the Ca_1-xSr_xTiO₃ (0 ≤ x ≤ 0.7) composition series were fabricated via conventional solid state, mixed oxides route. The structural, microstructural and microwave dielectric properties of the sintered samples were investigated. The XRD patterns revealed the formation of a single-phase perovskite-structured compositions calcined at 1000 °C for 3 h in air. The structure was observed to be transformed from noncentrosymmetric orthorhombic (Pnma) to centrosymmetric cubic (Pm3m) at 0.5 ≤ x. Microwave dielectric properties like relative permittivity (ε_r), quality factor (Qxf) and dielectric loss (tan δ) were measured at relatively lower frequency for millimeter (mm) wave wireless applications.
