MICROSTRIP PASS-BAND FILTER Russian patent published in 2013 - IPC H01P1/00 H03H9/46 

FIELD: radio engineering, communication.

SUBSTANCE: microstrip pass-band filter comprises a dielectric substrate (1), onto one surface of which a grounded base (2) is applied, and onto the second surface strip conductors are applied, which are connected in the form of a closed rectangular frame, at the same time two strip conductors (3), arranged on the short side of the rectangular frame, have different width, two strip conductors (4) have stepped variation of width, besides, in parallel to the closed rectangular frame, along long sides, there are strip conductors applied (5), which are electromagnetically connected to it.
