Abstract The original magnesium titanate powders were pre-sintered, and the 0.95MgTiO3-0.05CaTiO3 (95MCT) ceramics were prepared by the pre-sintered magnesium titanate showed better dielectric properties than by the original powders. Because the magnesium titanate (MgTi2O5) phase was not detected. Then the microwave patch antenna was designed by the prepared ceramic measured at 2.8 GHz exhibited a 4.83% bandwidth (return loss ≤ −3 dB) of the center frequency.

预烧结工艺对微波天线用95MCT的影响

摘要 对钛酸镁原粉进行预烧结，预烧结钛酸镁制备的0.95MgTiO3-0.05CaTiO3(95MCT)陶瓷具有比原粉更好的介电性能。因为没有检测到钛酸镁 (MgTi2O5) 相。然后用制备的陶瓷设计微波贴片天线，在 2.8 GHz 下测量显示中心频率的 4.83% 带宽（回波损耗≤ -3 dB）。
