SEALED WAVEGUIDE-TO-STRIPLINE TRANSITION Russian patent published in 2022 - IPC H01P5/107 

FIELD: microwave technology.

SUBSTANCE: invention relates to the field of ultra-high frequency (microwave) technology, radio engineering and can be used, for example, in electromagnetic energy transmission lines in receiving and transmitting antenna modules, measuring equipment. A sealed waveguide-to-stripline transition contains a waveguide section connecting radio engineering devices made in sealed enclosures and matching stages. The waveguide section is made of titanium alloy and is a rectangular waveguide with a cross section of 19 mm by 7.5 mm, one end of the rectangular waveguide is connected to one radio engineering device by means of a flange connector, matching stages are made in the inner space on the lower wide wall of the rectangular waveguide from its middle to the second end of the rectangular waveguide, providing the possibility of a coordinated transition to another type transmission lines, in the end part from the side of the matching stages there is a sealed inlet, mounted on a solder paste and providing an electrical connection by means of an internal conductor from the second radio device to the end part of the matching stages, while the waveguide-to-stripline transition is made with the possibility of rotating radio devices 360° relative to each other along the longitudinal axis of the waveguide section without disturbing the electrical connection.

EFFECT: increase in the efficiency of the device associated with minimizing transitions from different types of transmission lines, the possibility of rotating connecting devices relative to the longitudinal axis, maintaining tightness between different types of transmission lines, increasing structural strength, expanding the operating frequency range.
