摘要: 在本論文,我們將在橫向電磁波的假設下,使用空間替代法分析非均勻耦合 微帶傳輸線的方法.此法能快速計算非均勻耦合微帶傳輸線的反射係數,以 確定非均勻耦合微帶傳輸線的阻抗匹配效果,我們也使用等效串接網路鏈 的方法去確認上述結果.我們以兩條及三條的錐狀微帶線結構,當作理論說 明,最後並以一個測量電路驗證理論之正確性. In this thesis, we present a method for analyzing coupled non- uniform microstrip transmission lines in the frequency domain quasi-TEM assumption. The method incorporates a Chebyshev expansion into the telegrapher's equations. The method is proved to be very efficient and flexible to predict the reflection coefficients. From the calculated reflection coefficients,the matching performanceof the coupled nonuniform transmission lines can be known. We validate the results using an equivalent cascaded network chain method. The results of a two-line and a three-line tapered microstrip structures are reported. Finally a two-line coupled nonuniform microstrips is measured. The measure- ment has good agreement with the calculated data.
