MICROWAVE FILTER Russian patent published in 2022 - IPC H01P1/203 

FIELD: microwave technology.

SUBSTANCE: invention relates to the technique of ultrahigh frequencies, in particular to filters. The microwave filter contains a dielectric substrate, on one side of which a grounded base is applied, and on the second side electromagnetically connected strip conductors are applied, consisting of extended wide segments offset relative to each other, grounded to the base from the free ends. On the opposite side, they are connected to each other by means of extended segments of strip conductors, and on the inside with segments of extended narrow strip conductors. At the same time, extended wide segments of four strip conductors are grounded to the base from the free ends through a pair of L-shaped segments, and from the inside, each of them, except the extreme ones, is connected to a single extended narrow segment of the strip conductor. These narrow adjacent segments are located parallel to each other and are made in pairs.

EFFECT: increase in power suppression on both sides of the bandwidth.
