Dielectric Properties of (Mg(1-x)Cox)2SnO4 for Application in Dielectric Resonator Temperature Sensor
The microwave dielectric properties of (Mg1-xCox)2SnO4 were investigated by X-ray diffraction (XRD) patterns, Rietveld refinement, Raman spectroscopy, and microstructural observation. The ceramic was prepared using the conventional solid-state reaction method. (Mg0.95Co0.05)2SnO4 ceramic that was sintered at 1550 °C for 4 h had a dielectric constant ( ) of 8.3, a quality factor (εr) of 8.3, a quality factor (Q×f) of 120,200 GHz (at 17.6 GHz), and a temperature coefficient of resonant frequency (τf) of -63 ppm/°C. The development process and test results of dielectric resonator antenna temperature sensor composed of (Mg0.95Co0.05)2SnO4ceramics were recorded. The resonant frequency and 3 dB bandwidth measured at room temperature were 17.566 GHz and 17.0 MHz, respectively. The sensitivity of -1.1 MHz/°C was successfully achieved.
