Definitions
- the quality of the electrical connection depends on how tight the two flanges screwed together, soldered or are glued. So all of these connection techniques are supposed to on the one hand a mechanical connection between the Coaxial line and the waveguide and the other one Establish good electrical contact between the two. A high demands on the quality of the electrical connection such a galvanic contact can only with a relatively high amount of connection technology realize.
- a coaxial waveguide transition is shown in each case an inner conductor of a coaxial line is electromagnetically coupled to a waveguide.
- the waveguide consists of two interconnectable housing parts, one of which is the Inner conductor carries. In a parting plane between the two housing parts is in the vicinity of the A filter structure that reflects the coupled waves.
- the invention is therefore based on the object Arrangement for coupling a probe to a waveguide to indicate which for the electrical connection of the to the Connection cable belonging to the probe with the waveguide requires as little effort as possible.
- the object is achieved by a device with the Features of claim 1 solved.
- the probe can for example the inner conductor of a coaxial line, whose outer conductor with the housing part carrying the probe is galvanically connected.
- the probe can also be moved from one to the other strip line extending from a substrate, where das.Subat forms a housing part, and one for Stripline belonging to the ground plane of the substrate in the Separation level between the two housing parts.
- the probe be it the inner conductor of a coaxial line or the extension of a stripline
- carrying Housing part needs only mechanically with the other Housing part of the waveguide to be connected.
- the mechanical connection between the two housing parts does not need additional high demands on you electrical connection.
- a purely mechanical Connection requires less effort Joining techniques.
- the invention between the filter structure realized in both housing parts namely that the waves coupled by the probe in the Separating plane of the two housing parts are reflected so that there is no impairment of the coupling by not ideal galvanic contacts at the fastening points between the two housing parts.
- FIG. 1 shows a cross section through a waveguide 1 shown, which consists of a first housing part 2 and a second housing part 3 exists.
- the first is 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 one Probe 4 protrudes into the waveguide.
- the probe 4 of the Inner conductor of a coaxial line the outer conductor 5 with the housing part 3 formed as a cover galvanically connected is.
- a filter structure is provided in the parting plane between the two housing parts 2 and 3 of the waveguide 1 is around the opening for the probe 4 .
- the one shown in Figure 2 Section A-A through the waveguide parallel to the parting plane this shows the coupling opening 7 surrounding the waveguide 1 Filter structure 6, which here, for example, as Waffle iron structure is executed.
- This filter structure 6 causes waveguide waves to reflect in the parting plane be so that connection points further away between the housing part 3 and the housing part 2, the waves do not affect.
- the filter structure 6 is closed dimension that this effect over the whole Usable frequency range of the coupled waves occurs. you can the filter structure either in the base body 2 (as in shown in the drawing) or in the lid 3 or in both Provide housing parts 2 and 3.
- Parting plane between the two housing parts 2 and 3 am outermost edge of the waveguide 1
- others can Layers can be selected for the parting plane.
- the waveguide shown in Figure 1 has one Cross-sectional jump 8 on the function of a Has impedance transformation, but none for the invention Role play.
- the probe 3 shows the same waveguide 1 as in FIG. 1 shown, the same housing part 2 as a base body for the waveguide 1 and also with a Filter structure 6 provided parting plane to a cover trained second housing part 9.
- the probe 4 belongs to one in this embodiment Stripline 10, which on a housing part 9th forming substrate.
- the probe 4 is with the Stripline 10 is contacted by the substrate 9 the opposite side passes through and protrudes into the Waveguide 1 into it.
- On the waveguide 1 facing Side of the substrate 9 is the to Strip line 10 belonging to ground plane 11.
- the ground plane has a recess 12 around the probe 4. Together with the filter structure 6, the ground surface 11 ensures that already described above the reflection in the parting plane penetrating waves.
- the trained as a cover for the waveguide 1 Housing part be it the one connected to the coaxial line conductive plate 3 or the stripline substrate 9 either with a few screws or simply by gluing (no contact adhesive required) with the other Housing part 2 connected.
- the probe protruding into the waveguide can also be used Discontinuities are provided to deal with a optimal adaptation to the widest possible frequency range between the line belonging to the probe and the Achieve waveguide. To optimize the customization between the strip line and the waveguide can also on the stripline substrate near the probe Adaptation means are provided.
