New Wilkinson Power Dividers Based on Compact Stepped-Impedance Transmission Lines and Shunt Open Stubs

This study presents new Wilkinson power dividers using compact stepped-impedance structures and capacitive loads to achieve the required power splitting. This approach can produce additional transmission zeros and efiectively suppress the desired stopbands because shunt open stubs realize capacitive loads. This study proposes two equal-split dividers and two unequal-split dividers. For the flrst equal-split case, one shunt open stub forms the needed capacitor in each transmission path, creating one additional transmission zero in each path. To obtain one more transmission zero in each transmission path, the second Wilkinson power divider uses two shunt open stubs in each path to achieve the same capacitor value as the flrst divider. This study also tests unequal-split dividers with one and two transmission zeros in each path to conflrm that compact stepped-impedance transmission lines and shunt-to-ground capacitors can be utilized in unequal power division.
