Abstract
Zinc-substituted magnesium titanate ZnxMg1−xTiO3 (x = 0.00–0.10, δx = 0.025) solid solutions were synthesized using auto-ignition combustion process and characterized for structural, dielectric and reflection properties. X-ray diffraction analysis discovered the creation of single-phase MgTiO3. Scanning electron microscopy (SEM) indicated the existence of low porosity closely packed grains. The study of the dielectric properties indicated that for ZnxMg1−xTiO3 with x = 0.05, a reasonably great combination of the relative permittivity (ɛr) with value 16.60, loss tangent (tanδ) of 0.9 × 10−3 and temperature coefficient of resonant frequency (τf) of − 41.37 ppm/°C at 10 kHz was observed. The electromagnetic reflection analysis at microwave frequencies (12.4–26.5 GHz) revealed that composition x = 0.05 shows maximum 90% reflection bandwidth of 5.60 GHz in the Ku frequency band and 4.59 GHz in the K frequency band. These materials with low to intermediate relative permittivity, low losses, and a minor negative temperature coefficient of resonant frequency might be utilized as a resonator, antenna, and filter substrate for next-generation communication devices.
