摘要

研究了(Mg0.93Ni0.07)2SnO4陶瓷的微波介电性能，以期将其应用于无线高温介质谐振器天线温度传感器。在1550℃下烧结4 h的(Mg0.93Ni0.07)2SnO4陶瓷的介电常数为8.1，质量因子为124,200 GHz，谐振频率温度系数为- 67 ppm/°C。记录了介质谐振器天线温度传感器的研制过程和测试结果。在25°C下测得的谐振频率和3db带宽分别为12.62 GHz和53 MHz。成功地实现了−0.99 MHz/°C的灵敏度。

A high-quality factor dielectric resonator antenna for use in a wireless high-temperature sensor

Abstract The microwave dielectric properties of (Mg0.93Ni0.07)2SnO4 ceramics were examined with a view to their exploitation for wireless high-temperature dielectric resonator antenna temperature sensor. A dielectric constant of 8.1, a quality factor of 124,200 GHz, and a temperature coefficient of the resonant frequency of −67 ppm/°C were obtained for (Mg0.93Ni0.07)2SnO4 ceramics that were sintered at 1550 °C for 4 h. The developing procedures and test results for dielectric resonator antenna temperature sensor were recorded. The resonating frequency and 3 dB bandwidth measured at 25 °C were 12.62 GHz and 53 MHz, respectively. A sensitivity of −0.99 MHz/°C was successfully achieved.
