SEALED WAVEGUIDE-MICROSTRIP JUNCTION Russian patent published in 2023 - IPC H01P5/107 

FIELD: radio engineering.

SUBSTANCE: sealed waveguide-microstrip junction contains a piece of rectangular waveguide shorted at one end with an end wall, having a possibility to connect to the sealed volume and having a rectangular slot and a double-sided PCB with an end metallization. One side of the PCB has a terminating element, and the other side has a terminating element and a microstrip line. A cavity with a rectangular slot is made in the wall of the sealed volume, into which a PCB is sealed by soldering through a plate having a rectangular slot, so that part of each of the matching elements and the microstrip line are located in the sealed volume, in turn, the PCB is installed in the rectangular slot of the end wall, so that another part of each of the matching elements is located in a segment of the rectangular waveguide

EFFECT: invention disclose reduction of the overall height dimensions of the microwave module or unit in which the claimed sealed waveguide-microstrip junction is used.
