BROADBAND SIMPLE TOPOLOGY CIRCUIT FOR SUPPLYING DIRECT CURRENT TO A STRIP LINE Russian patent published in 2023 - IPC H01P1/15 

FIELD: radio engineering.

SUBSTANCE: circuits for supplying direct current to strip lines. A broadband DC supply circuit to a strip line contains a central, short-circuited, quarter-wavelength stub at the mid-frequency range with increased impedance. One end of the cable is connected to the strip line, and the other end is connected to a capacitor, the opposite side of which is grounded. A short-circuited loop is connected to the middle of a line segment with a length equal to half a wave at the middle frequency of the range, and with a lower impedance than the main line, which is included in the regular main line.

EFFECT: improved transmission characteristics.
