在本論文內將討論0.34CaTiO3-0.66Ca(Mg1/3Nb2/3)O3介電陶瓷材料，藉由分別添加不同燒結促進劑B2O3、CuO、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1250℃，此時可得介電特性εr~44，Q×f~29700 (7GHz)，τf~-1.9 (ppm/oC)。

　　另外，本論文以FR4、氧化鋁、0.34CaTiO3-0.66Ca(Mg1/3Nb2/3)O3為基板，製作一個堆疊的步階阻抗濾波器，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 0.34CaTiO3-0.66Ca(Mg1/3Nb2/3)O3 dielectric ceramic materials are discussed in this paper. By adding different sintering aids B2O3、CuO and V2O5 respectively, we study the effects of liquid phase for the microwave properties of 0.34CaTiO3-0.66Ca(Mg1/3Nb2/3)O3. The experimental results show that 0.34CaTiO3- 0.66Ca(Mg1/3Nb2/3)O3 with 0.25wt% B2O3 addition can efficiently reduce sintering temperature from 1450 oC to 1250 oC, and the dielectric properties the ceramics are εr~44，Q×f~29700(7GHz) and τf~-1.9(ppm/oC).

　In addition, a stacked stepped-impedance resonator filter on R4, Al2O3 and 0.34CaTiO3-0.66Ca(Mg1/3Nb2/3)O3 are fabricated. The experimental measurements demonstrate that the ceramic 0.34CaTiO3-0.66Ca(Mg1/3Nb2/3)O3 with added sintering aids can be used for microwave applications for their superior microwave properties of low loss, smaller device area, high Q*f value and high relative dielectric constant substrate.
