MICROSTRIP BROADBAND BAND-PASS FILTER Russian patent published in 2018 - IPC H01P1/203 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to radio engineering, in particular to filters. Microstrip broadband band-pass filter contains a dielectric substrate, one side of which is fully metallized and performs the function of a grounded base, and irregular strip conductors of resonators are applied on the other side. Narrow areas of the irregular conductors of the external resonators are short-circuited on one side of the screen, and the internal resonators are conductively connected at one end to each other and connected to external short-circuited conductors with the help of additional conductors. Input and output transmission lines are connected to the conductors of the external resonators, which are orthogonal to the conductors of the internal resonators up to the point of their conductive connection with additional conductors.

EFFECT: increasing the compactness of the device, increasing the length of the high-frequency band of the barrier of the microstrip broadband band-pass filter.
