本論文是以Sm(Mg1/2Ti1/2)O3系統為基礎，根據Hume-Rothery規則，利用Co+2(0.082nm)、Zn+2(0.075nm)的離子半徑與Mg+2(0.078nm)的離子半徑接近，進行取代，並以固態反應法完成Sm(A1/2Ti1/2)O3，(A = Zn、Co)系統之微波介電材料，並藉由添加燒結促進劑B2O3，降低燒結溫度，來量測其特性並討論之。
　　在濾波器元件的實作方面，利用直接耦合的方式來製作矩形微帶線帶通濾波器，並使用FR4、Al2O3、Sm(Co1/2Ti1/2)O3做為濾波器的基板，比較之間的差異。藉由高介電常數與品質因數來縮小濾波器的體積與獲得良好的頻率響應。濾波器設計的規格：中心頻率2.45GHz及5.25GHz，使用電磁模擬軟體IE3D來進行電腦模擬並與實作量測結果做比較，以得到元件縮小化之實現。

　　Based on Sm(Mg1/2Ti1/2)O3 system, this thesis was to discuss the microwave properties of Sm(A1/2Ti1/2)O3, (A=Zn, Co) dielectric ceramic materials. According to Hume-Rothery rule, the ion radius of Co+2(0.082nm ) and Zn+2(0.075nm ) are close to the ion radius of Mg+2(0.078nm ); therefore, Co+2 and Zn+2 were used to replace Mg+2 to finish the reaction of Sm(A1/2Ti1/2)O3, (A=Zn, Co) microwave dielectric materials. Addition of sintering aid B2O3 reduced the sintering temperature. The properties of Sm(Co1/2Ti1/2)O3 dielectric ceramic materials were measured and discussed.
　　In addition, we designed and fabricated microstrip rectangular ring filter component on FR4, Al2O3 and Sm(Co1/2Ti1/2)O3 substrate. The center frequency 2.45GHz and 5.25GHz were designed and simulated by electromagnetic simulation software, IE3D.
