本論文首先提出一個小型化的圓極化槽孔天線設計,進而相繼提出一些新穎的設計方法與概念,達到增進圓極化軸比頻寬的目的,不僅具有小型化與寬頻圓極化的設計要點,並且同時具有單向輻射場形的設計特色。首先,一個大幅縮小天線尺寸的圓極化正方形槽孔天線設計,利用一個叉形共面波導饋入信號線,藉由調整其垂直與水平段金屬微帶的長度,可形成良好的圓極化操作,並且天線的圓極化和阻抗匹配可分別獨立完成。其次,為改善小型圓極化槽孔天線設計之具有窄頻帶的圓極化特性,除了同樣使用一個叉形共面波導饋入訊號線以外,並且利用ㄧ個在槽孔內浮接的正方環形金屬貼片形成高、低頻段的圓極化頻帶,結合形成的寬頻圓極化操作。一個特殊設計的金屬反射體,可形成單向輻射操作,並且維持與原有雙向輻射天線相近的圓極化頻寬。再者,為一大幅增寬圓極化軸比頻寬的正方形槽孔天線設計,以不對稱T形共面波導饋入結構,取代原有的叉形結構設計,可產生一個11%的圓極化頻寬,藉由一個在饋入結構延伸出的長直金屬微帶和一個浮接長方形金屬貼片,達到增加圓極化頻寬4倍的設計,並且利用一個植入的接地金屬微帶降低圓極化頻帶,完成阻抗匹配,達到縮小化的設計目標。最後,提出一個新穎的寬頻圓極化正方形槽孔天線的設計方法,同樣採用不對稱T形的共面波導饋入結構,形成在低、高頻段兩個圓極化頻帶。植入的接地金屬微帶,將高頻段圓極化頻帶降頻,並且藉由植入的L形接地金屬微帶,來達到優化整個圓極化頻帶的軸比值,完成寬頻圓極化的設計目的。使用一個特殊設計的金屬反射體,達到具有單向輻射特性的天線設計,並且提高天線的輻射增益。
In this thesis, we propose firstly a compact-size circularly polarized (CP) square slot antenna (SSA) design. The next, we propose new procedures and concepts to enhance the axial-ratio bandwith (ARBW). The proposed antennas not only have the campact-sizes and broad ARBWs but also have the unidirectional CP patterns. The first one is a new miniaturized CP SSA fed by a halberd-shaped co-planar waveguide (CPW). The good ARs can be obtained by adjusting the lengths of vertical and horizontal strips of feedline. The characteristics of the design are that the CP operation and impedance matching can be achieved independently. The second design, we propose a newly designed compact wideband CP SSA, to ehance the ARBW of first design, in the square slot of which are a halberd-shaped feeding line and a square ring patch. By placing a specially designed reflector behind the bidirectional CP SSA, one can obtain unidirectional CP patterns with the associated 3-dB ARBW almost the same as that of the bidirectional antenna. The third design, we propose a greatly enhanced ARBW for CP SSA. We replace the halberd-shaped CPW feeding line by an asymmetrical T-shaped one to gain a 3-dB ARBW about 11%. The 3-dB ARBW can largely increase to 4 times by a stretched metal strip and an embedded rectangular metal patch in square slot. A grounded metal strip is employed to result that the CP band can be moved to lower ones to obtain the compact design and achieve the optimum impedance matching. The last design, we propose a novel procedure for broadband CP SSA. We employ the asymmetrically T-shaped CPW feedline as same as the third design to obtain the lower and higher CP band. The higher CP band can be lowered by the implanted grounded strip and the ARs improved by the grounded L-shaped strip. The unidirectional patterns can be gained and the radiating gains increased by the specially designed reflector.
