Abstract

In modern microwave systems, a wide variety of frequency-selective devices are used, which are performed according to certain technologies. Waveguide microwave filters are currently a rapidly developing class of functional devices. The variety of manufacturing technologies, calculation methods and designs of such filters is great. In this paper, we consider a band-pass filter on a rectangular waveguide with a cross section of 35×15 mm, in which, instead of the classic thin plane-transverse diaphragms, plane-longitudinal diaphragms are used. Four classical rectangular windows are used as a resonant window, which makes it possible to conduct electrodynamic analysis and show good convergence of the calculation and simulation results. Calculations were performed using the computer-aided design environment CST Studio.
