HIGH-SELECTIVE HIGH-PASS STRIP FILTER Russian patent published in 2020 - IPC H01P1/205 

FIELD: radio equipment.

SUBSTANCE: invention relates to radio engineering, particularly, to ultrahigh frequency equipment. High-pass strip filter, containing a dielectric substrate suspended in a metal housing, on which there are irregular strip conductors of resonators, formed by connection of narrow and wide sections of a strip line, closed by the end of a narrow segment on the screen, and on the second surface under the wide sections of adjacent resonators there are additional strip conductors, characterized in that the filter is configured to change the frequency position of zeros of the transmission coefficient by varying the gap between the additional conductors with invariable parameters of the pass band.

EFFECT: wider pass band and high selectivity of the high pass strip filter.
