なる不具合がある。 First, in the mechanical bending method shown in FIG. 1, a long straight waveguide 1 is mechanically bent with a bend 2 and cut at a predetermined position 3. In this method, the cross-sectional shape of the waveguide changes due to mechanical bending, resulting in a problem of large variations in phase amount between products. In addition, the method of forming by electroforming as shown in Figure 2 is as follows: (1) Acrylic core 4
Do chemical plating 5. (2) Perform copper electroforming 6 on the chemical plating 5. (3) Place the whole thing in a low temperature bath, shrink the core 4, and remove it. Bend waveguides are manufactured through the above steps, but this method requires complicated processes, long flow times, and high costs.In addition, when brazing flanges on both ends, distortion occurs during the brazing process. There is a problem that this tends to occur and the accuracy deteriorates.

They are each joined together to form a donut shape, which is then divided into four parts in the circumferential direction.

きる。 Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 shows parts that have been precisely machined in advance; 11 is an outer ring, 12 is an inner ring, and 13 and 14 are side plates. These are welded and formed into a donut shape as shown in FIG. Note that the welding at this time is by electron beam welding, which is the least likely to cause distortion among various methods. Next, by cutting the doughnut-shaped tube into four equal parts as shown in FIG. 5, a bent waveguide can be obtained.

Additionally, the reduction in manufacturing steps shortens flow time and reduces costs.
