Analysis and design of a novel coupled-line wideband Wilkinson power divider

In this paper, a novel compact wideband Wilkinson Power Divider (WPD) is proposed and is analyzed by using the even-and oddmode theory. The even-mode equivalent circuit of the WPD is designed to have both a wide stopband and a wide passband. The passband is then used as the wide operating frequency band of the WPD with low return loss. The even-mode circuit parameters are determined by using the derived formulas and an optimization algorithm. The remaining circuit parameters of the WPD are obtained from the analysis of the odd-mode circuit of the WPD. Finally, a microstrip WPD is designed with a center frequency of 3.0 GHz and an operating frequency band covering 1.5 ~ 4.5 GHz (FBW=100%). The microstrip WPD is compact, occupying an area of only 0.20 × 0.13 , and its measured performance satisfies the design specifications quite well.
