在2014提出了由兩段短傳輸線、兩段四分之一波長傳輸線、隔離電容及隔離電阻所組成的新式威爾金森功率分配器，但因此兩段四分之一波長傳輸線關係，導致電路尺寸過大。故本論文提出四種功率分配器電路，分別以T型及π型混合電路做輸出埠的阻抗轉換器替代，並使其電路尺寸縮小。且本論文在操作頻率下的實驗結果會與2014所提出的新式威爾金森功率分配器實驗結果相似。

In 2014, a Wilkinson power divider composed of two short lines, two quarter-wavelength (λ/4) transformers, an isolation resistor, and an isolation capacitor was proposed. However, the circuit area has a large size caused by the two λ/4 transformers. Thus, this study presents four power dividers using mixed T-shaped and -shaped circuits to design impedance transformers near output ports and then compact circuit sizes can be achieved in the all proposed circuits. In the operating band, similar results are obtained between the proposed dividers and the previous divider in 2014.
