Abstract: A waveguide half-wave resonator with a stub and filter designs based on it are considered. It is shown that the location of the stub in the center of a half-wave resonator leads to an increase in signal attenuation near the passband of filters compared to filters based on half-wave resonators. Using this type of resonator, the pole can be obtained both below the passband and above. The geometric dimensions of the four- and eightsection filters with a symmetrical frequency response are given.

Keywords: waveguide resonator, stub, attenuation pole, band pass filter

Funding: The study was carried out within the framework of the state assignment of the Federal State Autonomous Educational Institution of Higher Education “Siberian Federal University” (number FSRZ-2023-0008).
