In this paper, thermal stable Y 3 MgAl 3 SibO 12 -TiO 2 microwave composite ceramics were firstly fabricated by the high temperature solid phase reaction method. The influence of the sintering temperature , microstructure on microwave dielectric properties of Y 3 MgAl 3 SiO 12 by doping TiO 2 were investigated in detailed. TiO 2 addition reduced the ceramic sintering temperature and improved the distribution of grain size. The negative temperature coefficient of resonant frequency (τ f  = −32 ppm/°C) of Y 3 MgAl 3 SiO 12 was adjusted to near zero value. 0.8Y 3 MgAl 3 SiO 12 -0.2TiO 2 ceramic sintered at 1475 °C for 6 h achieved the optimized microwave dielectric properties: ε r  = 12.2, Q ×  f  = 21,050 GHz, τ f  = +5.2 ppm/°C, which indicated that 0.8Y 3 MgAl 3 SiO 12 -0.2TiO 2 is a potential candidate for dielectric patch antenna and substrate.
