MICROSTRIP BROADBAND BANDPASS FILTER Russian patent published in 2015 - IPC H01P1/203 H03H9/17 

FIELD: radio engineering, communication.

SUBSTANCE: microstrip broadband bandpass filter comprises a dielectric substrate, one side of which is coated with a grounded base and the second side has strip conductors, one of the strip conductors being in the form of an irregular meander. Extended strip conductors which are grounded on the base on the side of the free ends of the meander are deposited in parallel along the longer sides of the filter, said strip conductors being electromagnetically coupled with both the meander and the outermost extended strip conductors different from the latter on length and width.

EFFECT: wider operating frequency band and improved selective properties.
