The implemented filters contain two-order, three-order, and four-order ones which possess the Chebyshev’s response. These filters structures are fabricated on the two-layer PCB board. Specifically, suitable inductive and capacitive couplings are introduced such that one-pair of ransmission zeros may be created to realize a 4th-order filter with elliptic response to improve the filter selectivity. Finally, used step-impedance resonator for filter design , and implement by two-layer substrate RO4003. Because of the slow-wave effect of step-impedance resonator, the size of filter is small and stopband response is better.第一章 簡介 .................................1 1-1 研究動機............................1 1-2 文獻回顧...........................3 1-3 本論文章節簡介......................4 第二章 基板合成波導..........................7 2-1 矩形導波管.........................7 2-2 基板合成波導.......................8 2-3 共振腔饋入電路.....................14 第三章 基板合成波導帶通濾波器................19 3-1 濾波器簡介..........................19 3-2 阻抗轉換與頻率轉換.................24 3-3 分散式濾波器之理論與分析...........26 3-4 耦合濾波器.........................36 3-5 共振頻率與 耦合係數的粹取..........39 第四章 帶通濾波器研製........................53 4-1 二階基板合成波導濾波器實作.........53 4-2 三階基板合成波導濾波器實作..............55 4-3 四階基板合成波導濾波器實作.........57 4-4 基板合成波導濾波器的改良...........63 第五章 結論..................................92 參考文獻.....................................945343225 bytesapplication/pdfen-US濾波器filterthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/58786/1/ntu-95-R93942063-1.pdf
