[Industrial application field]

The present invention relates to an adjustment structure for a waveguide converter used in a microwave band communication device, and in particular, a simple waveguide converter in which an adjustment screw is screwed into the other side of a dielectric support into which an inner conductor is fitted. Regarding the adjustment structure of the device.

In recent years, with the rapid progress of wireless communication and the expansion of its range of use, there has been a trend toward higher frequencies (microwaves, millimeter waves, etc. with shorter wavelengths) being used in these devices. The printed wiring board uses a dielectric substrate with low high-frequency loss, and has a microstrip line on one side and a ground pattern on the other side to connect the microstrip line and the inner conductor inserted into the waveguide. Connected waveguide transducers are often used.

[Conventional technology]

FIG. 2 is a side sectional view of a main part explaining the adjustment structure of a conventional waveguide converter.

In the figure, a microstrip line 1 made of a conductor is formed on one side of a dielectric substrate 2 made of ceramic or the like, and a ground pattern 3 is formed on the other side, so that the ground pattern 3 is in contact with a casing 4. to be implemented. Then, the inner conductor 5 is inserted into the dielectric pillar 6 made of Teflon or the like and has an insertion hole 61 for the inner conductor 5 in the waveguide 7, and the inner conductor 5 is formed on the dielectric substrate 2 to form a microstrip line. This is a structure in which 1 and 1 are connected.

[Problems to be Solved by the Invention] In the adjustment structure of the conventional waveguide converter described above, the inner conductor fitted into the dielectric pillar inserted into the waveguide protrudes into the waveguide. The dimensions (shown in Figure 2) greatly affect the characteristics of the waveguide converter, and to adjust it, the protruding dimensions of the inner conductor must be adjusted, making adjustment difficult and requiring a large amount of man-hours. There was a problem that it was necessary.

[Means for Solving the Problems] The present invention solves the above problems and provides a simple adjustment structure for a waveguide converter that does not require dimensional adjustment of the inner conductor.

That is, a dielectric support 8 into which an inner conductor 5 connected to a microstrip line 1 formed on a dielectric substrate 2 is fitted.
The adjusting structure of the waveguide converter in which the inner conductor 5 is inserted into the waveguide 7 is inserted into the dielectric support 8 through a screw hole 8 on the other side where the inner conductor 5 is inserted.
2, and screw the adjustment screw 9 into this screw hole 82,
This problem can be solved by adjusting the thread size.

[Effect]

The adjustment structure of the above-mentioned waveguide converter is to fit an inner conductor into a dielectric support that is inserted into the waveguide, and screw in an adjustment screw from the other side where this inner conductor is inserted. The waveguide converter can be easily adjusted by taking it in and taking it out.
