Abstract

The effect on the microwave properties was investigated for the barium titanate doped with impurity of $WO_{3}$ 0.230 mole% produced by conventional solid state reaction method. Microwave resistance, reactance and impedance of the barium titanate were measured with 2-port s-parameter method by using network analyzer, in the range of room temperature to $160^{\circ}C$ and of frequency 300 kHz to 300 MHz. And possibility of frequency sensor and temperature sensor was estimated with barium titanate doped with $WO_{3}$.

$WO_{3}$가 첨가된 $BaTiO_{3}$를 고상법으로 제작하여 상온에서 $160^{\circ}C$의 온도 범위와 300 kHz - 300 MHz의 주파수 범위에서 회로망분석기를 이용하여 2포트 S-파라메터 방법으로 고주파 저항, 리액턴스 및 임피던스를 측정하여 $130^{\circ}C$ 이하에서 주파수 및 온도센서로서의 가능성을 진단하였다.
