摘要註:	在這篇論文中，提出一個利用步階式阻抗傳輸線和電容性負載的新式威爾金森功率分配器。在這各架構中的電容性負載是串接在兩個輸出端附近，而這兩個電容性負載是可以很容易的利用兩個開路殘段來替代與製作，因此，可以避免掉使用離散元件所造成的不連續效應，這樣就不會因為不連續效應而得到不想要的影響，而這樣的結構也可以縮小的電路面積並且提供良好的隔離度。除此之外，我們所提出結構擁有慢波(slow wave)的特性，此特性可以把第一諧波頻率推往較高頻率點，也代表著可以改善非工作頻率段的響應。此研究中，設計等功率和不等功率分配器所需要的公式是被推導出來，利用此公式可以得到可設計的參數解，此參數解所實作出來的電路佈局也證明了所需電路面積小於傳統的威爾金森功率分配器。 A new Wilkinson power divider utilizing stepped impedance transmission lines and capacitive loads is presented. In this design, the capacitive loads are shunted near two output ports and can be implemented easily by two open stubs; as a result, the usage of lumped capacitors, which may cause some unexpected discontinuity, can therefore be avoided. Based on this structure, a small circuit area and high isolation between two output ports can be achieved at the same time. Furthermore, the proposed divider is a slow wave structure capable of pushing the first harmonic to a higher frequency, meaning that the non-operating band responses can also be improved. In this study, the design equations of equal and unequal power ratio dividers have been derived for designing the proposed power dividers. Besides, the implemented circuit layouts also show that the sizes thereof are smaller than that of the conventional Wilkinson power divider.
