COMPACT COAXIAL WAVEGUIDE ADAPTER OF THE PROBE TYPE Russian patent published in 2023 - IPC H01P5/103 

FIELD: microwave technology.

SUBSTANCE: invention is related to compact coaxial waveguide transitions of the probe type. The coaxial waveguide transition contains a section of regular waveguide 1, shorted by end wall 2, and a section of coaxial line 3 located perpendicular to it, which is laid along the inner side of the wide wall of the regular waveguide. The coaxial line at the entrance to the waveguide and at its end inside the waveguide along the outer metal shell is galvanically connected to the wall of the waveguide, for example, by soldering. Cylindrical probe 4 is connected to the central conductor of the coaxial line at the end of the line located inside the waveguide, parallel to the electric field inside the waveguide, while the axis of the probe is perpendicular to the axis of the coaxial line. The distances from end wall 2 to probe 4, from the ends of probe 4 to the wide walls of the waveguide, and from the cylindrical surface of probe 4 to the metal sheath of coaxial line 3 inside the waveguide are selected according to the minimum reflection coefficient of the transition as a whole.

EFFECT: simplification of the design of coaxial waveguide transition and the possibility of implementing the most compact coaxial waveguide transition with a parallel arrangement of the waveguide and the coaxial line.
