在本論文內將討論0.93(Mg0.7Zn0.3)TiO3-0.07CaTiO3介電陶瓷材料，分別藉由添加不同燒結促進劑B2O3與V2O5，探討產生的液相對其微波特性的影響。實驗結果顯示，添加0.25wt%的B2O3可有效降低燒結溫度到1200℃，此時可得介電特性εr~23.58，Q×f ~74100 (8.9GHz)，τf ~+1.41 (ppm/℃)。
另外，本論文以FR4、氧化鋁、0.93(Mg0.7Zn0.3)TiO3-0.07CaTiO3為基板，製作一個濾波器，利用電腦軟體模擬與實作的測量值比較，可獲得縮小濾波器的面積與較好的頻率響應結果。

The microwave properties of 0.93(Mg0.7Zn0.3)TiO3-0.07CaTiO3 dielectric ceramic materials are discussed in this paper. By adding different sintering aids B2O3 andV2O5, we studied the effects of liquid-phase aids for the microwave properties of 0.93(Mg0.7Zn0.3)TiO3-0.07CaTiO3. The experimental results showed that of 0.93(Mg0.7Zn0.3)TiO3-0.07CaTiO3 with 0.25wt% B2O3 addition could efficiently be reduced the sintering temperature from 1300℃ to 1200℃ and the dielectric properties of the ceramics were εr~23.58，Q×f ~74100(8.9GHz) and τf ~+1.41(ppm/℃).
In addition, a stacked stepped-impedance resonator filter on FR4, Al2O3 and 0.93(Mg0.7Zn0.3)TiO3-0.07CaTiO3 substrates were fabricated. The experimental measurements demonstrate that the ceramic 0.93(Mg0.7Zn0.3)TiO3-0.07CaTiO3 with the sintering aids are applicable for microwave applications because of their superior microwave properties of low loss, smaller device area, high Q×f value and high relative dielectric constant substrate.
