Dual band bandpass filter type Wilkinson power divider with microstrip composite resonators
A dual band bandpass filter type Wilkinson power divider is newly introduced in this paper. 2 degree bandpass filter topology with J inverters and composite series resonators is designed to replace two l/4 transmission lines in Wilkinson power divider application. Based on filter design theory, design equations are summarized by even and odd mode analysis. In experiment, one proposed Wilkinson power divider with central frequencies of 2.4 GHz and 5.2 GHz is designed and fabricated. There is good agreement between the simulated and measured results.
