Annotation: 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.
