    Abstract: 本論文分為兩個部分,第一部分為微型化雙頻帶通濾波器設計,是結合傳輸線、耦合線以及接地電桿的方式,設計出微型化雙頻帶通濾波器。此電路具有尺寸極小、隔離度好以及選擇性高等優點,可進而提升雙頻帶通濾波器特性。 第二部分介紹四工器應用於無線擴音模組,使用四組帶通濾波器作為基本單位架構來設計四工器,其基本單位架構包含分佈式耦合饋入線、分佈式耦合輸出線與一對C型諧振腔,然後把四工器應用於含有四個頻段的無線擴音模組系統之中。上述兩個電路設計,使用電磁模擬軟體IE3D進行模擬輔助,以及實際製作電路進行量測。經由電磁模擬與量測的結果比較,兩者具有良好的一致性。
    The thesis contains two parts. The first part will introduce a design of compact dual-band bandpass filters ,which combine the transmission lines, parallel coupled lines and grounded inductor are integrated to design a compact dual-band bandpass filters. The proposed circuit has compact size, high isolation, and high selectivity….etc. of benefits to improve the performance of dual-band bandpass filters. The second part will introduce a quadruplexer for wireless microphone system.We use four band pass filters as unit cells and put those four cells together to design a quadruplexer for wireless microphone system. The unit cell contains distributed coupling feed line, distributed input/output lines and a pair of C-shaped resonators.We eventually put quadruplexers into wireless microphone system for application. These two circuits are simulated with electromagnetic simulator software IE3D, and the prototype of these two circuits are fabricated and measured. Comparing the simulated results with the experimental data, we can see that the measured results can match well with the EM simulation.
