Microwave dielectric properties of (1-x)ZnW $O_4$-xTi $O_2$ ceramic systems were investigated with calcination temperatures and Ti $O_2$ contents. The ZnW $O_4$ ceramic could be suitably sintered at 1075$^{circ}C$ and showed the dielectric constant of 13.6, quality factor(Q$ imes$ $f_{O}$value) of 22,000 and temperature coefficient of resonant frequency($ au$$_{f}$) of -65$pm$2ppm/$^{circ}C$. Increasing the amount of Ti $O_2$ in the range of 0.25 to 0.45 mol, the dielectric constant and $ au$$_{f}$ increased due to the role of Ti $O_2$ but the quality factor decreased due to the increase of phase boundaries. The 0.7ZnW $O_4$-0.3Ti $O_2$ ceramic showed the dielectric constant of 19.8, qualify factor(Q$ imes$ $f_{0}$) of 20,000 and $ au$$_{f}$ of -3$pm$1ppm/$^{circ}C$.>.EX>.>.>.
