っていた。Conventionally, as shown in FIG. 3, this type of coaxial waveguide converter has a dielectric converter provided inside a rectangular waveguide 1 at a position approximately 1/4 wavelength away from the short-circuiting surface 2 in terms of the tube wavelength. It had a structure in which a tubular antenna conductor pin 5 was inserted into a body sleeve 4.

ある。In the conventional coaxial waveguide converter described above, the position of the waveguide short-circuit surface 2, the protrusion distance of the antenna conductor pin 5 into the waveguide, and the dielectric sleeve 4 are determined by the mechanical precision during manufacturing.
Due to variations in shape, impedance deviations occur in the band of use, which has the drawback of not being able to be manufactured with good reproducibility. Furthermore, when shifting the used band, there is a drawback that all the antenna parts used must be replaced.

It has the original content of being able to change the electrical length of the antenna within the waveguide.

In order to guide the waveguide 1, a dielectric sleeve 4 is inserted from the lower surface of the waveguide 1, an antenna conductor pin 5 (tubular shape with a stepped portion on the outer periphery) is inserted into the dielectric sleeve 4, and an antenna conductor pin 5 is inserted into the dielectric sleeve 4. A dielectric sleeve 6 is inserted to fix the position of the pin 5 within the dielectric sleeve 4.

ねじにより固定されている。Furthermore, dielectric rods 7 are inserted into the dielectric sleeve 6 to prevent these dielectric rods 7 from protruding from the lower surface of the waveguide 1 and falling. For this purpose, an antenna support metal plate 8 is fixed to the lower surface of the rectangular waveguide 1 with screws.

This embodiment differs from the embodiments shown in FIGS. 1(a) and 1(b) in that a metal ring 9 is inserted between the lower end of the antenna conductor pin 5 and the upper end of the dielectric sleeve. In the example shown in FIG. 1(a), the metal ring 9 and dielectric sleeve 6 are replaced.

めに有効である。As explained above, the present invention has the advantage that the electrical length of the antenna can be freely changed by changing the length of the dielectric rod inserted into the second dielectric sleeve. In addition, by inserting a metal ring directly under the antenna conductor pin, the range in which the electrical length can be varied can be further expanded. Therefore, it is effective for matching when a product whose impedance is shifted due to variations in machining dimensions or the like is inserted.
