FIELD: physics.;SUBSTANCE: invention relates to microwave devices. Filter contains a substrate with a relative permittivity and thickness, on one side of which a metal screen is made, on the opposite side of the substrate there is an irregular strip conductor rolled in the form of a meander, wide and narrow segments thereof are microstrip resonators connected to each other in a cascade, forming five parallel rows, with wide segments in adjacent rows opposite the narrow ones.;EFFECT: improvement of the frequency-selective properties of the microstrip low-pass filter, improving the manufacturability of its manufacture, as well as reducing the size of the structure.;1 cl, 2 dwg
