dc.description.abstract | 論文中我們提出了利用四分之一波長及準四分之一波長諧振腔的微型微帶線交錯耦合濾波器。四分之一波長諧振腔可使我們為了實現正交錯耦合或負交錯耦合濾波器的面積更小。我們一提出了一個新的諧振腔結構,即為準四分之一波長諧振腔。因為準四分之一波長諧振腔的左右兩側有一百八十度的相位差,因此我們只要用四分之一波長及準四分之一波長諧振腔任意組合以達到恰當的相位就可以達成我們欲設計的交錯耦合濾波器。在此論文中我們提出了一個新的方法來解釋交錯耦合與主耦合間相位不同所產生的各種響應。我們可利用此相位比較的方法預測我們所提出的濾波器其頻率響應的結果。 在此論文的最後,完成了應用兩種諧振腔任意組合成的八種不同的濾波器。這八種濾波器分別為三階和四階,且符合廣義柴比契夫函數的響應或是擁有平緩傳輸延遲。電路的量測結果也相當符合理論預測值。 | zh_TW |
dc.description.abstract | Miniaturized microstrip filters using quarter-wave or quasi-quarter-wave resonator with cross coupling is proposed in this paper. The quarter wavelength resonators make filter very compact for realizing a positively or negatively cross-coupled filter. The combination of quarter-wave and quasi-quarter-wave resonator makes it easy to realize a cross coupling with proper coupling phase. A new explanation for the coupling phase between main coupling and cross coupling is proposed. Different kinds of filters using proposed resonators are realized, which can have either quasi-elliptical function response or flat group, delay response. The measured results matched well with theoretical prediction. | en_US |
