The circular wave guiding structures with various irregularities and layered dielectric filling set a class of devices which are widely used in the microwave equipment. The properties of various irregularities including selective properties allow using them as basic elements at development of various devices of microwave range.
In this work the general approach to synthesis of the waveguide filters is considered. The way of receiving initial approach of filter model which can be used for further characteristics optimization is described.
The problem of design of band-pass filters on circular waveguides is solved. The four-ridge circular waveguides are used as resonators and evanescent circular waveguides – as impedance. For increase of good quality and expansion of a filter stop-band it is offered to use circular dielectric inserts in a space between ridges of resonators. The results of modeling of filters on three resonators are presented.
