Definitions

a detachable connection is to be established between a coaxial line and a waveguide, suitable measures must be taken which ensure good galvanic contact between the outer conductor of the coaxial line and a waveguide wall.
Flange connection technology is usually used for this.
the quality of the electrical connection depends on how tightly the two flanges are screwed, soldered or glued together. All of these connection technologies are intended on the one hand to provide a mechanical connection between the Make coaxial line and the waveguide and on the other hand good electrical contact between the two.
a high requirement for the quality of the electrical connection of such galvanic contacting can only be realized with a relatively high outlay on connection technology.
the invention is therefore based on the object of specifying an arrangement for coupling a probe to a waveguide, which requires as little effort as possible for the electrical connection of the connecting line belonging to the probe to the waveguide.
the object is achieved according to the features of claim 1 in that the waveguide consists of two interconnectable housing parts, one of which carries the probe, and that a filter structure is present in the parting plane between the two housing parts in the vicinity of the probe, which the coupled waves reflected.
the filter structure can then be a waffle iron structure which is embedded in at least one of the two housing parts.
the probe can be, for example, the inner conductor of a coaxial line, the outer conductor of which is galvanically connected to the housing part carrying the probe.
the probe can also start from a strip line running on a substrate, the substrate forming a housing part, and a ground plane of the substrate belonging to the strip line lying in the parting plane between the two housing parts.
the housing part carrying the probe be it the inner conductor of a coaxial line or the extension of a strip line, merely needs to be mechanically connected to the other housing part of the waveguide.
the mechanical connection between the two housing parts does not additionally have to meet high requirements for an electrical connection.
a purely mechanical connection requires less complex connection techniques.
the filter structure realized according to the invention between the two housing parts namely causes the waves coupled by the probe to be reflected in the parting plane of the two housing parts in such a way that the coupling is not impaired by non-ideal galvanic contacts at the fastening points between the two housing parts.
the first housing part 2 is a base body in which the waveguide 1 is embedded, and the second housing part 3 has the function of a cover for the waveguide 1.
This cover 3 closes an opening of the waveguide 1 through which a probe 4 enters the Waveguide protrudes.
the illustrated embodiment is the probe 4 of the inner conductor of a coaxial line, the outer conductor 5 of which is galvanically connected to the housing part 3 designed as a cover.
a filter structure is provided around the opening for the probe 4.
the section A-A shown in FIG. 2 through the waveguide parallel to the parting plane shows this filter structure 6 which surrounds the coupling opening 7 in the waveguide 1 and which is designed here, for example, as a waffle iron structure.
This filter structure 6 has the effect that waveguide waves are reflected in the parting plane, so that connection points located further away between the housing part 3 and the housing part 2 do not influence the waves.
the filter structure 6 is to be dimensioned such that this effect occurs over the entire useful frequency range of the coupled waves.
the filter structure can be provided either in the base body 2 (as shown in the drawing) or in the cover 3 or in both housing parts 2 and 3.
parting plane between the two housing parts 2 and 3 lies at the outermost edge of the waveguide 1, other positions can also be chosen for the parting plane.
the waveguide shown in Figure 1 has a cross-sectional jump 8, which has the function of an impedance transformation, but does not play a role in the invention.
FIG. 3 shows the same waveguide 1 as in FIG. 1, the same housing part 2 as the base body for the waveguide 1 and also with a Partition plane provided filter structure 6 to a second housing part 9 formed as a cover.
the probe 4 belongs to a strip line 10, which runs on a substrate forming the housing part 9. The probe 4 is contacted with the strip line 10, is passed through the substrate 9 to the opposite side and protrudes into the waveguide 1.
the ground surface 11 belonging to the strip line 10 is located on the side of the substrate 9 facing the waveguide 1.
the ground surface has a recess 12 around the probe 4. Together with the filter structure 6, the ground surface 11 ensures the reflection of the surface of FIG waves penetrating the parting plane.
the probe protruding into the waveguide can be provided with discontinuities in order to achieve an optimal adaptation between the line belonging to the probe and the waveguide over the broadest possible frequency range.
adaptation means can also be provided on the stripline substrate in the vicinity of the probe.
