STRIP-LINE BANDPASS FILTER Russian patent published in 2010 - IPC H01P1/203 

FIELD: radio engineering.

SUBSTANCE: device comprises dielectric substrate suspended between two screens, on both surfaces of which there are strip metal conductors applied, being electromagnetically connected to each other. Conductor on the firs surface of substrate is open at the ends and is arranged in the form of pin, and two conductors arranged on the second surface of substrate under open ends of the first conductor are closed to screen by adjacent ends at one edge of substrate. Besides on the second surface of substrate there is an additional conductor arranged under central part of open conductor, and it is closed to screen by one end.

EFFECT: reduced dimensions of narrow-band bandpass filters and improvement of their selective properties.
