BAND PASS FILTER Russian patent published in 2018 - IPC H01P1/203 

FIELD: electrical engineering.

SUBSTANCE: invention relates to microwave technology and can be used in selective paths of receiving and transmitting systems. Band-pass filter contains a dielectric substrate, on one side of which a grounded metallized base is applied, and a strip conductor partially split by a longitudinal slit at one end is applied on the second. New is the fact that the unsplit strip of the strip conductor from the slot side is grounded to the metallized base through the hole in the dielectric substrate, and the slit-split segments of the strip conductors are folded U-shaped, while the band-pass filter may contain n electromagnetically connected spaced cords of the strip conductors, where n = 2,3,4 etc.

EFFECT: band pass filter according to the invention has a wider relative bandwidth and better frequency-selective properties.
