窄頻帶中使多重耦合微帶線相速相等之簡易法

Abstract

在本論文中,提出一種使多重耦合微帶線相速相等的技巧﹐此法利用調 整上金屬蓋做補償來達成﹐其次我們利用耦合微帶共振環及直線形多重耦 合微帶線驗證模擬結果﹐本文所介紹的補償方法可以應用在需要相速相等 的窄頻帶電路設計中。 This thesis proposes a housing-height compensation technique to equalize the modal phase velocities of multiple coupled microstrip lines. Measurements using coupled annular ring resonators and section of multiple coupled microstrip lines are performed to validate the technique. It is found that this method is suitable for the design of coupled lines where equal phase velocities are required for narrow band purpose.
