STRIP HARMONIC FILTER Russian patent published in 2016 - IPC H01P1/203 

FIELD: radio engineering and communications.

SUBSTANCE: invention is intended for use in selective channels of radio equipment for different purposes. Filter comprises dielectric substrate on one side of which there are strip conductors, pole mains switch with one end, and on second side there are also strip conductors, short-circuited from one end. Conductors forming each of filter resonators, are located on different surfaces of substrate and shorted by opposite ends. According to invention width of strip conductors forming resonators, at least in one of them differs by at least 1.1 times from width of strip conductors of other resonators.

EFFECT: expansion of high-frequency band while maintaining high manufacture ability.
