摘要: | 本論文提出兩種無線個人通訊系統中寬頻且低成本的手機接收天線.設計 和分析不同型態饋入線的平面印刷式天線:第一種是以共平面微帶線為金 屬平面板天線的饋入線;第二種是以雙側耦合微帶線為金屬板天線的饋入 線.我們使用以三角形基底為主的混位積分方程配合動差法來分析這兩種 結構.我們也改善平衡饋入線的設計並討論其對天線性能的影響.最後,以 測量結果驗證數值資料的正確性. This thesis presents two types of wideband and low-cost hand-set receiving antennas for wireless personal communication systems. Printed planar bow-tie antennas with different feed lines are designedand analyzed.One is formed by coplanar patches with coplanar-strips (CPS) feed line,and the other is formed by patches with broadside-coupledfeed line.Both configurations are analyzed using themixed-potential integral equation(MPIE) solved with triangular-basis domain with the Galerkin method of moments.The design of baluns on the feed-line circuits and their effects to the performances of these antennas are discussed and improved.Finally,the measurement datas are shown to be in good agreement with the numerical data. |
