SINGLE-SECTION WILKINSON POWER DIVIDER

WIPO Patent Application WO/2018/218995

A1

The present invention relates to a single-section Wilkinson power divider. The single-section Wilkinson power divider comprises: a dielectric layer, and an input port, a first output port and a second output port which are located on the dielectric layer, a first branch line provided between the input port and the first output port and having matched input and output, a second branch line provided between the input port and the first output port and having matched input and output, an isolation resistor provided between the first output port and the second output port, and a first open circuit microstrip line and a second open-circuit microstrip line respectively provided at two ends of the isolation resistor and used for introducing a reflection zero. Two ends of the isolation resistor being respectively connected to the first open circuit microstrip line and the second open circuit microstrip line is equivalent to introducing a transmission zero, improving characteristics, such as the operation bandwidth, of the single-section Wilkinson power divider, such that the single-section Wilkinson power divider above has the advantages of a simple structure, ultra-wideband, low insertion loss, and small layout area.
