Sinterability and microwave dielectric properties of $xZWO_{4}-(1-x)TiO_{2}$ ceramic systems with zinc-borosilicate glass and $TiO_{2}$ contents for LTCC(Low Temperature Co-fired Ceramics) were investigated. The addition of $3{sim}10;wt%$ ZBS glass ensured the sinterability below $900^{circ}C$. In general, increasing ZBS glass content seemed to enhance the sinterability, but the quality factor($Qxf_{0}$) significantly decreased due to the formation of an excessive liquid and second phases. As for the addition of $TiO_{2}$, the dielectric constant(${varepsilon}_{r}$) and temperature coefficient of resonant frequency(${ au}_{f}$) showed to increase, while the quality factor($Qxf_{0}$) did not show an apparent change. The composition of $0.7xZnWO_{4}-0.3TiO_{2}$ ceramics sintered at $900^{circ}C$ with 5 wt% ZBS glass demonstrated 21.6 in dielectric constant(${varepsilon}_{r}$), 14,800 in quality factor($Qxf_{0}$), and $+5;ppm/^{circ}C$ in temperature coefficient of resonant frequency(${ au}_{f}$).
