本論文將討論介電陶瓷材料x(Mg0.95Zn0.05)TiO3-(1-x)Na0.5La0.5TiO3系統，藉由正負共振頻率溫度係數，使其達到共振頻率溫度係數為零值。(Mg0.95Zn0.05)TiO3 的微波特性為 ~17.1，Q × f ~264,000在9GHz以及 約-40 ppm/℃；Na0.5La0.5TiO3為 ~122， Q × f ~9800以及 約480 ppm/℃，調整x值使其頻率溫度飄移係數趨近於零。除此之外，嘗試添加不同燒結促進劑B2O3、CuO，探討其添加量對材料微波特性的影響。實驗結果顯示，當x=0.88且燒結溫度在1300℃持溫4小時下具有良好的微波特性：Q×f~103000(9GHz)， ~23.39， ~1.1(ppm/)℃。
最後，本論文以FR4、氧化鋁、自製基板，使用雙模態曲折形環形共振器製作設計一中心頻率定為2GHz的帶通濾波器，再利用電腦模擬與實做量測結果比較。

The microwave properties of x(Mg0.95Zn0.05)TiO3-(1-x)Na0.5La0.5TiO3 dielectric ceramic materials have been discussed in this paper.Using positive and negative temperature coefficients would achieve zero temperature coefficient of resonant frequency. Na0.8La0.5TiO3 has dielectric properties of ~122，Q × f value ~9800 and a positive value ~ 480 ppm/℃. (Mg0.95Zn0.05)TiO3 possesses high dielectric constant ( ~17)，high quality factor (Q × f ~260,000 at 9GHz) and negative value(-40 ppm/℃).By appropriately adjusting the x value in the x(Mg0.95Zn0.05)TiO3-(1-x)Na0.5La0.5TiO3 ceramic system, zero value can be achieved. The experiment results show that it has excellent dielectric properties(Q×f~103000(9GHz)， ~23.39， ~1.1ppm/oC) when x value equal to 0.88. Besides, we attempt to add different sintering aids B2O3 and CuO respectively and discuss the effects of the microwave properties by various amounts of sintered aids. 0.88(Mg0.95Zn0.05)TiO3-0.12Na0.5La0.5TiO3.
Finally, we design and fabricate a band-pass filter using dual-mode meader loop resonators with 2GHz center frequency on FR4、Al2O3、88MZNLT substrate respectively. And we compared with the result of the simulation and measurement.
