第一高階漏波模槽線天線之設計

Abstract

本論文提出二種饋入方式激發有限導體槽線第一高階漏波模。第一種是使用平行帶線(parallel-strips)饋入, 第二種是使用微帶線(microstrip line)饋入,並比較以微帶線藕合(microstrip line coupled)饋入結構。文中提出一種饋入方法可達到不錯的頻寬。我們構建一模型來計算天線的輻射場型,最後,以量測結果驗證理論的正確性。

This thesis presents two types of feedline structure to excite the first slotline's higher order leaky mode. First type is parallel-strips fed, second type is microstrip line fed and to compare with microstrip line coupled fed. We use a fed method that can obtain wide bandwidth. We establish a modal to calculate antenna radiation patterns. Finally, the measurement results are shown to be in good agreement with the numerical results.
