| Popis: | The microwave dielectric characteristics of La(Mg0.5-xCaxSn0.5)O3 ceramics are studied for application in the dielectric resonator antenna temperature sensor network. La(Mg0.49Ca0.01Sn0.5)O3 ceramics that were sintered at 1600 °C for 4 h have a bulk density of 6.57 g/cm3, a dielectric constant (er) of 19.9, a quality factor (Q × f) of 94,300 GHz, and a temperature coefficient at the resonant frequency (TCF) of − 87 ppm/°C. The respective sensitivity of − 88.96, − 93.40, and − 91.02 ppm/°C for sensor 1, sensor 2, and sensor 3 is achieved. The linearity of sensor 1, sensor 2, and sensor 3 is 6.6%, 6.7%, and 6.3%, respectively. |
