本論文提出一種應用在GPS系統之圓極化陶瓷天線在非對稱接地面上設計。首先在非對稱接地面上置入一L形狹縫型槽孔,使之分離成兩個獨立接地面,也就是讓天線所屬之接地面為對稱的,接下來在極細同軸線上利用四分之一阻抗轉換方式來有效阻隔兩接地面之表面電流,使得天線在正常操作時其接地面上產生的表面電流能分佈均勻,在操作頻帶上產生一良好的圓極化輻射場型。
Design of the circularly polarized ceramic antenna, suitable for GPS system, on an asymmetric ground plane is presented in this thesis. Firstly, to obtain two isolated ground planes, we insert an L slit on an asymmetric ground plane, making the antenna with a symmetric ground plane. Then, we isolate the excited surface current between the two ground planes by using a quarter-wavelength mini-coaxial cable. The surface current can distribute uniformly on the ground plane when the proposed antenna is in operation, which makes possible a good circularly polarized radiation pattern in the operation band.
