The(1-x) MgTiO$_3$-xSrTiO$_3$(x=0.03~0.04) ceramics were fabricated by the conventional mixed oxide method. The structural and microwave dielectric properties were investigated by XRD, SEM, EDS and network analyzer. The sintering temperature and time were 1275$^{circ}C$~135$0^{circ}C$ and 2hours, respectively. In the XRD results of 0.96MgTiO$_3$-0.04SrTiO$_3$ceramics, the perovskite structure of SrTiO$_3$and ilmenite structure of MgTiO$_3$phase were coexisted. The dielectric constant($varepsilon$(sub)${gamma}$) and temperature coefficient of resonant frequency($ au$(sub)f) were increased with addition of SrTiO$_3$. In thie case of 0.96MgTiO$_3$-0.04SrTiO$_3$ ceramics sintered at 13$25^{circ}C$, the dielectric constant, quality factor(Q) and temperature coefficient of resonant frequency($ au$(sub)f) were 20.13, 7956(at 7.27GHz), and +1.76ppm/$^{circ}C$, respectively.
