초록

Microwave dielectric properties of A1$_2$O$_3$ ceramics resonator were investigated with impurity addition. Increasing the contents of Bi$_2$O$_3$Q-value and Q $\times$ f were increased. In the specimen with the content of Bi$_2$O$_3$(0.3wt%), dielectric constant, quality factor and temperature coefficient of resonant frequency(TCRF, $\tau$$_{f}$) had a good values of 10.76,23,253(at 9.68[GHz]) and -39.09(ppm/$^{\circ}C$), respectively. The TCRF value was decreased with MnO$_2$ and increased with Sm$_2$O$_3$. La$_2$O$_3$.>.
