Union between a microstrip line and a waveguide.

摘要

Arrangement for a junction between a line micrDisposición to a junction between a microstripline and a waveguide, comprising - a líobanda and a waveguide, comprising - a microstrip line (ML) applied to a supenea side microstrip (ML) applied to an upper side of a dielectric substrate (S), - a derior guide a dielectric substrate (S), - a waveguide applied on the upper side of sustrat waves applied on the upper side of the substrate ( S) with an opening (OB) on at least one superfo (S) with an opening (OB) on at least a front surface, a side wall of the guide ICIE front, in a side wall of the waveguide is a metallized layer (LS) on sobde waves is a metallized layer (LS) formed on the substrate (s), - a recess (a) made lre the substrate (s), - a recess (a) held in the layer metallised (LS), into which surplus metallized layer (LS), to dent ro which protrudes the microstrip line (ML) through aesale the microstrip line (ML) through the opening (OB) into the waveguide, - ubertura (OB) into the guide waves - a rear-face metallization (RM) on Sobna rear-face metallization (RM) held on a rear side of the substrate (S), - holes dere a rear side of the substrate (S), - vias (VH) electrically conductive ent interconnection (VH) electrically conducting between the metallized layer (LS) on the upper side re the metallized layer (LS) on the upper side of the substrate (S) and the metallization traserodel side substrate (S) and metallizing rear side (RM), which surround the recess (a), CHARACTERIZATION (RM), which surround the recess (a), characterized in that in the region of the opening (OB) of guada because the area of ​​the opening (OB) of the waveguide in a side wall opposite the ladoía wave in a a, opposite to the upper side of the substrate (S) of the waveguide, and upper substrate (S), the waveguide side wall is made a stepped structure (ST) conecstá made a stepped structure (ST) conductively connected to the line Tada microstrip conductively to the microstrip line (ML) in at least one part (ST1), in that escal (ML) in at least one part (ST1), in that the steps the stepped structure (ST) have a aones of stepped structure (ST) have an increasing width in the longitudinal direction, increasing apanchura in the longitudinal direction, away from the junction of the waveguide. rtada binding of the waveguide.
