Abstract

In order to improve the microwave dielectric properties of ZnO+$TiO_2$ ceramic systems, we studied the relations among microstructures, phases, and microwave dielectric properties at various mole ratio and sintering temperatures. The optimum composition was found to be 0.2ZnO+0.8$TiO_2$ when sintered at $1100^{\circ}C$, at which we could obtain following results: $Q{\times}f_o$ = 22,500 GHz, ${\varepsilon}_r$ = 73, and $\tau_f=+210ppm/^{\circ}C$.
