The possibility of application of pseudocombline microwave structures with λ/2 resonators manufactured from sections of balanced striplines as bandpass filters is demonstrated. It is found that coupling coefficients of λ/2 resonators manufactured from sections of balanced striplines arranged in parallel to each other without mutual shift have nonzero values. The dependence of these coupling coefficients on the parameters of half-wave stripline resonators is studied. Frequency characteristics of some pseudocombline bandpass filters with λ/2 resonators are analyzed and experimental data are presented.
