UWB PASS FILTER USING STEPPED IMPEDANCE GROUND CIRCUIT STUB AND OPEN STUB

摘要

The present invention is to provide a UWB pass filter in which a radial combined open stub is added to the principle of a stepped impedance ground circuit stub and a triple mode resonator including the same. The UWB pass filter comprises: first and second multiple coupled lines, wherein a central transmission line is configured in a horizontal direction and multiple coupled lines are configured between an input side port and an output side port of the central transmission line; a stepped ground stub having a stepped impedance ground circuit stub structure on one side in a direction vertical to the central transmission line between the first multiple coupled line and the second multiple coupled line; a first open stub having a radial combined open stub structure on one side in the direction vertical to the central transmission line between the input side port and the first multiple coupled line; and a second open stub having a radial combined open stub structure on one side in the direction vertical to the central transmission line between the output side port and the second multiple coupled line.;COPYRIGHT KIPO 2016
