BANDPASS MICROWAVE FILTER Russian patent published in 2018 - IPC H01P1/203 H03H9/00 

FIELD: electronics.

SUBSTANCE: bandpass microwave filter belongs to the technique of ultrahigh frequencies and can be used in selective ducts of receiving and transmitting systems. Filter comprises dielectric substrate (1), on one side of which there is grounded base (2), and on the second one there are strip conductors (2-19) of three electromagnetically interconnected resonators applied. Novelty is in fact, that the narrow and the wide rectangular strip conductors interconnected in series and grounded to the base from the free end of the input (output) of the strip conductor are three times folded in the form of an irregular meander. Also, the filter is characterized in that the strip conductors are folded p times in the form of an irregular meander, where p = 5, 7, 9, …, and it contains n electromagnetically interconnected resonators, where n = 4, 5, 6, … .

EFFECT: technical result of the claimed solution is to improve frequency-selective properties of the band-pass microwave filter.
