FIELD: electricity.
SUBSTANCE: invention relates to microwave engineering and is intended for frequency selection of signals. In a highly selective microstrip bandpass filter, the strip conductors of at least one pair of adjacent resonators are closed by one end to the screen on opposite sides, and their open ends are galvanically connected to each other by an additional strip conductor, length and width of which are selected from the condition of formation of transfer coefficient zeros at required frequencies.
EFFECT: high selectivity of a bandpass filter.
