In this study, a compact four equal way Wilkinson Power Divider (WPD) circuit design was designed for UHF applications. The circuit whose center frequency was selected as 0.8 GHz operates between the frequencies of 0.54-1.08 GHz and has a bandwidth of approximately 67.5%. The length of each outlet way has been curved to take up less space in the circuit. In this respect, the proposed WPD has a compact structure with high applicability. A butterfly stub, the length of which was determined by parameter sweep, has been placed in the input for the purpose of matching impedance.
The simulation and measurement results of the designed circuit were well aligned with each other below 15 dB Return Loss and Isolation. In addition, 0.3 dB Insertion Loss was obtained on the output ways. It has been calculated that the proposed four-way power divider takes about 40% less space than the conventional circuit design.
