在本論文內將討論AB2O6（ZnTa2O6、MgTa2O6、MgNb2O6）介電瓷材料，分別添加不同CuO及B2O3含量時，產生的液相對其微波特性的影響。實驗結果顯示，適當的燒結促進劑除了降低AB2O6的燒結溫度外，亦使其頻率漂移係數趨近於零。
另外，本論文以氧化鋁及MgNb2O6為基板，製作一交錯耦合的slow-wave open-loop 濾波器。其規格為：中心頻率4.5GHz、頻寬為2.6％。

The effects of microwave dielectric properties of AB2O6 (MgNb2O6、MgTa2O6 and ZnTa2O6) adding different amounts of sintering aids B2O3 and CuO which could produce liquid phase have been discussed in this paper. The results show that adding sintering aids not only lower the sintering temperature of AB2O6 ceramics but shift the temperature coeifficient of resonant frequency toward to zero. Besides, a cross-coupling slow-wave open-loop filter on Al2O3 and MgNb2O6 substrates have been design.The bandpass frequency is 2.45GHz,the bandwidth is 2.6％.
