Title:
WILKINSON POWER DIVIDER
Document Type and Number:
WIPO Patent Application WO/2019/085368
Kind Code:
A1
Abstract:
The present invention relates to a Wilkinson power divider, comprising a dielectric layer, a signal metal layer attached to one side of the dielectric layer, and a metal underlayer attached to the other side of the dielectric layer, wherein the signal metal layer, the dielectric layer and the metal underlayer form a microstrip line structure, and the signal metal layer comprises: microwave transmission branches for dividing one path of microwave signals into at least two paths of microwave branch signals; output ports for outputting the at least two paths of microwave branch signals, wherein the number of output ports matches the number of microwave transmission branches; and electromagnetic bandgap structures, wherein the electromagnetic bandgap structures are provided at positions of the output ports and are used for suppressing harmonics generated by the output signals of the power divider. Compared with a traditional Wilkinson power divider for carrying out out-of-band harmonic suppression by means of adding an additional harmonic suppression filter circuit, the Wilkinson power divider of the present invention effectively suppresses the higher harmonics of output signals, and greatly reduces the layout area of a circuit.
