Abstract
We have fabricated (Sr1-xMgx)TiO3, (x = 0.00 & 0.3) sintered ceramics by mixed oxide route and studied the structural and microwave dielectric property of the samples with respect to variation of frequency (1 GHz to 2 GHz) using Impedance spectroscopy. This study revealed that the XRD patterns shown cubical structure along with space group (Pm-3m) while SEM images shown spherical like grains of the samples. The microwave dielectric properties of the samples vary with Mg2+ dopants and operating frequency as well. The distinctive absorption peak of hydroxyl vibration at 1350 cm−1 was observed for both samples while hydroxyl vibrational mode was also observed only in doped sample at 3000 cm−1. The microwave dielectric properties strongly depend upon Mg2+ contents and resonating frequency. The optimum microwave dielectric properties have been recorded which may help for the application of microwave wireless communication devices.
