0.15$(Ba_{0.95}Sr_{0.05})$O-0.15$(Sm_{2(1-x)}Nd-{2x})O_3-0.7TiO_2 (x=0{\sim}10[m/o])$ ceramics were fabricated by mixed-oxide method. Microwave dielectric properties was investigated with the contents of $Nd_2O_3$. Increasing the contents of $Nd_2O_3$ from 0 to 6[m/o], sintered density was increased 5.53 to $5.68[g/ cm^3]$. In the specimen with contents of $Nd_2O_3$(6[m/o]), dielectric content was maximum value of 78.14 and decreased with increasing the contents of $Nd_2O_3$. Quality factor was increased with the contents of $Nd_2O_3$.
