DEVICE FOR ISOLATING DC INPUT AND OUTPUT OF MICROSTRIP LINE Russian patent published in 2025 - IPC H01P5/18 

FIELD: microwave equipment.

SUBSTANCE: device for isolating input and output of microstrip line by direct current, comprising a section of connected microstrip lines with high-resistance microstrip loops connected to opposite ends of connected sections of microstrip lines, connected in series to open low-resistance microstrip loops. Microstrip short-circuits in the form of open sector loops are used as open low-resistance loops.

EFFECT: providing reliable isolation of the input and output of a microstrip line with a quasi-TEM wave without significant attenuation of the transmitted microwave signal in a wide band covering up to one and a half octaves.
