本篇論文主要分別介紹四大部分，第一、二和三部分將介紹新開發的微波介電材料，第四部分介紹濾波器的模擬與實測。
首先第一部分為Li2Co2(MoO4)3陶瓷之微波介電特性，由實驗結果發現，在燒結溫度為840℃並持溫4小時擁有最佳的微波介電特性ε_r~9.1、Q×f~34,000 GHz、τ_f~-72 ppm⁄℃。第二部分為Li2Ni2(MoO4)3陶瓷之微波介電特性，觀察實驗結果，在燒結溫度為660℃並持溫4小時擁有最佳的微波介電特性ε_r~9.6、Q×f~28,000 GHz、τ_f~-71 ppm⁄℃。第三部分為利用Zn2+去進行少量取代，探討Li2Ni2-xZnx(MoO4)3 (0≤x≤0.1)陶瓷之微波介電特性，觀察實驗結果，在燒結溫度為660℃，x=0.05的Li2Ni1.95Zn0.05(MoO4)3擁有最佳的微波介電特性ε_r~10.9、Q×f~56,000 GHz、τ_f~-62 ppm⁄℃ 。
最後第四部分，我們以HFSS模擬濾波器電路，並將電路實作於FR4、氧化鋁、Li2Ni1.95Zn0.05(MoO4)3基板上，由結果可知，高介電常數能使電路面積縮小且高Q×f提高濾波器在頻率選擇上的表現。

In order to obtain a novel low-temperature co-fired ceramics, microwave dielectric properties of Li2Co2(MoO4)3 and Li2Ni2-xZnx(MoO4)3 (0≤x≤0.1) ceramics had been investigated. The experimental results show that Li2Co2(MoO4)3 has best properties at sintering temperature 840℃ for 4 hours, with ε_r~9.1, Q×f~34,000 GHz and τ_f~-72 ( ppm)⁄℃﹔the Li2Ni2(MoO4)3 has best properties at sintering temperature 660℃ for 4 hours, with ε_r~9.6 Q×f~28,000 GHz and τ_f~-71 ( ppm)⁄℃ ﹔the Li2Ni1.95Zn0.05(MoO4)3 has best properties at sintering temperature 660℃ for 4 hours, with ε_r~10.9 Q×f~56,000 GHz and τ_f~-62 ( ppm)⁄℃.In this paper, the band-pass filter was designed with Square open-loop resonator which contains Open-stub. According to the results of measurements, the performance of the filter was improved by using low-loss dielectric ceramics as the substrate, and its size was reduced by using high dielectric constant ceramics.
