Development of theory and circuit solutions of non-minimum-phase planar filters with mixed couplings for telecommunications

Development of theory and circuit solutions of non-minimum-phase planar filters with mixed couplings for telecommunications

The object of the study is non-minimal-phase radio-wave filters of planar design (stripline and microstrip), which, in addition to reflection-type resonators, contain through-type resonators, and which use mixed electromagnetic couplings between resonators.
The subject of research is the influence of mixed electromagnetic coupling on the frequency characteristics of more complex non-minimal-phase planar filters, which should lead to the creation of a new theory.
