在本論文中將探討 Nd(Zn1/2Ti1/2)O3 陶瓷系統的微波介電特性及材料的微結構。由實驗結果顯示，Nd(Zn1/2Ti1/2)O3在1330℃燒結4小時，可得最佳之介電特性εr~31.55，Q׃~170000(at 8.55GHz)，τƒ~-42 ppm/oC。由於τƒ為負值，我們選擇添加 CaTiO3(+850 ppm/oC) 及 SrTiO3(+1100 ppm/oC)調整其τƒ。再者，添加CuO使其燒結溫度降低到1270℃~1300℃。
此外，本論文還分別以FR4、Al2O3及Nd(Zn1/2Ti1/2)O3作為基板來設計一緊密微帶線帶通濾波器，濾波器的規格為:中心頻率 2GHz、頻寬約5%，並使用電磁模擬軟體HFSS 來進行電腦模擬。

The microwave dielectric properties and the microstructures of the series of Nd(Zn1/2Ti1/2)O3 ceramics system were investigated. The experiment results show that
Nd(Zn1/2Ti1/2)O3 has the best properties with sintering temperature at 1330℃, the dielectric properties are εr ~ 31.55 , Q×f ~ 170000(at 8.55 GHz) , τƒ ~ -42 ppm/oC. Concerning about the negative value of τƒ, we choose adding the CaTiO3 (+850 ppm/oC) and SrTiO3 (+1100 ppm/oC) to adjust the value. The CuO additives lowered the sintering temperature of NZT ceramics to the range 1270℃~1300℃.
Besides, a compact microstrip bandpass filter on FR4、Al2O3 and Nd(Zn1/2Ti1/2)O3 substrates have been design. The band-pass frequency is 2GHz, the bandwidth is 5% and simulated by electromagnetic simulation software, HFSS.
