提出了一种无源LC无线温度传感器。该传感器设计为螺旋电感和叉指电容的并联连接，并采用LTCC（低温共烧陶瓷）技术制作在导电层中。叉指电容器电极涂覆有铋掺杂的钛酸钡（Ba0.9Bi0.066TiO3）的薄膜，其介电常数随温度变化，这直接引起叉指电容器的电容变化，从而改变传感器的谐振频率。使用矢量网络分析仪（E5071B，Agilent Technologies，Santa Clara，CA，USA）进行传感器的S参数的测量，其端口连接到放置在传感器周围的天线线圈，以便能够无线检测温度，温度范围为25 °C至165 °C。
This paper presents a passive LC wireless sensor for measuring temperature. The sensor is designed as a parallel connection of a spiral inductor and an interdigitated capacitor and it was fabricated in a conductive layer using LTCC (Low Temperature Co-fired Ceramic) technology. The inderdigitated capacitor electrodes were coated with a thin film of bismuth doped barium titanate (Ba0.9Bi0.066TiO3), whose permittivity changes with temperature, which directly induces changes in the capacitance of the interdigitated capacitor and consequently changes the resonant frequency of the sensor. The measurements of S-parameter of the sensor were performed using a Vector Network Analyzer (E5071B, Agilent Technologies, Santa Clara, CA, USA), whose port was connected to the antenna coil that was placed around the sensor in order to be able to wirelessly detect temperature, in the temperature range from 25 °C to 165 °C.
