緩變槽線天線陣列(Tapered Slot Antenna Array)乃是由單一緩變槽線天線(Tapered Slot Antenna)在E平面或是H平面所組合而成 因此，單一緩變槽線天線的特性將會被提出並做一簡單的討論 而有關於具有鋸齒狀邊緣槽線天線的特性及效應也會在此篇論文中作一比較以對此效應有更深入的瞭解 此外，我們也將介紹一種雙面鰭線(Bilateral Fin-line)饋入的線性緩變槽線天線並且在比較量測結果後發現可藉以設計出具有高增益及低交互極化位準(cross polarization level)的緩變槽線天線 最後，有關於兩種不同饋入結構所構成的線性緩變槽線天線陣列將會被設計操作在不同頻率 所有的設計程序以及量測的結果與有關的特性都將會在此篇論文中討論

The tapered slot antenna arrays were integrated the single element of the tapered slot antenna (TSA) on E- or H-plane. Therefore, the characteristics of the TSA will be made a review and discussed. The measured results of the single element of TSA with corrugated edges will be presented and compared with the single element of TSA to realize the effects of corrugated edges. We will introduce the bilateral fin-line fed linear tapered slot antenna (LTSA) and comparing the measured results with the unilateral fin-line fed LTSA to design a TSA which has high gain and low cross polarization level. Finally, the LTSA arrays of two different feeding structures will be proposed. The design procedures and the characteristics of the LTSA arrays will be discussed.
