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 $WO_{3}$.
