MICROSTRIP BANDPASS SHF-FILTER Russian patent published in 2023 - IPC H01P1/203 

FIELD: SHF radio technology, in particular, filters.

SUBSTANCE: microstrip microwave bandpass filter comprises a double-sided board having a dielectric substrate, on one surface of which a grounded base is applied, and a strip conductor is applied on the second surface. A double-sided board with a strip conductor made in the form of separate rectangular conductors of various lengths and widths connected in series is fixed on one side in the filter housing, while the input and output of the strip conductor are conductively connected through matching individual rectangular conductors with RF coaxial connectors installed respectively at the input and output of the filter housing, and the grounded base of the dielectric substrate is connected to the filter housing by means of screws, whereas the filter housing, having adjusting screws in the housing cover, is a transcendental waveguide at high frequencies.

EFFECT: expanding the functionality of the frequency-selective properties of the microstrip band-pass microwave filter while achieving high reliability and ensuring high manufacturability of its manufacture.
