Definitions

  • the present invention relates to a transition from a waveguide to a microstrip line, wherein a substrate penetrates into the waveguide, which is short-circuited at the end and is provided on one of its two sides with a strip line which projects into the inner region of the waveguide and which couples the waveguide waves and which is provided by a of the waveguide wall is guided channel, and which does not have an electrically conductive counter-coating to the strip conductor on the other side within the waveguide has a ground surface.
  • Such a waveguide-microstrip line transition is known from DE-PS 2 421 795.
  • a problem with the transition from a microstrip line, consisting of a strip line running on one side of a substrate and a ground surface applied on the opposite side of the substrate, to a waveguide is always the contacting of the ground area of the microstrip line with the waveguide, because the quality of the ground contact depends crucially the broadband and the loss of continuity of the transition.
  • the invention is therefore based on the object of creating a transition from a waveguide to a microstrip line of the type mentioned, in which the wave of the waveguide is converted into the microstrip line or vice versa with broadband and low attenuation.
  • the figure shows an opened, two-part housing, in the lower part 1 of which a substrate 2 is accommodated, on the top of which a strip conductor structure 3 is arranged and the underside of which is provided with a ground surface (hatched).
  • a rectangular waveguide piece short-circuited at its end is embedded in the front of the housing; namely, the rectangular waveguide piece is divided into two shells 4 and 5 according to the housing.
  • the dividing plane of the waveguide is where the wall currents running across this plane are minimal.
  • the waveguide is divided into two half shells.
  • the substrate 2 crosses the waveguide in the parting plane between the two shells 4 and 5.
  • ground surface of the substrate as the area not hatched and delimited by the dashed line shows, is removed in the region of the interior of the waveguide and the waveguide wall. There is therefore no contact between the ground surface of the substrate and the waveguide wall.
  • ground contact with the entire housing 1 can also be dispensed with.
  • a strip conductor 6 which acts as a coupling probe, is provided on the substrate, which leads laterally, parallel to the short-circuit wall 7, into the waveguide.
  • the distance of this strip conductor 6 from the short-circuit wall 7 is approximately 1 / s A G ... '/ 4 , G where ⁇ is the operating wavelength of the waveguide.
  • a channel 8 embedded in a side wall of the upper waveguide shell 5 serves as a contact-free passage of the strip conductor 6 into the waveguide.
  • the channel without substrate represents a waveguide operated below the cutoff frequency.
  • the ground surface belonging to the stripline begins on the underside of the substrate.
