Abstract
The synthesis procedure of the microstrip band-pass filter based on resonators with quarter-wave coupling is considered. The nonuniform microstrip line electromagnetic field complexity demands using of some mathematical models with the stepby-step field specificity taking into account, when the previous model calculations results become the initial data for the next model. The component coupling increases and new type wave modes appear when the frequency rises and the filter dimensions decrease. According to the concerned procedure: the filter in the 11 GHz band was designed (synthesized and made), the filter in the 26 GHz band was synthesized.
