Publication number: 20230198113Abstract: A stub tuner includes a first conductor, and a rod-shaped conductor shaft. The first conductor is inserted into a tube axial direction inner side from an opening in a waveguide tube transmitting high frequency waves. The first conductor includes a plate-shaped first shape extending in a direction intersecting a tube axial direction, inside the waveguide tube, and a plate-shaped second shape extending from the outer end in the tube radial direction of the first shape toward the tube axial direction outer side in the tube axial direction. An outer circumferential surface of the second shape is separated from an inner surface of the waveguide tube. An electrical length of the outer circumferential surface in the tube axial direction is ¼ of a wavelength of the high-frequency waves. The conductor shaft is electrically connected to the waveguide tube, supports the first conductor, and extends in the tube axial direction.Type: ApplicationFiled: February 23, 2023Publication date: June 22, 2023Applicant: FURUNO ELECTRIC CO., LTD.Inventors: Kazuyoshi FUJISAKI, Mitsuhiko Hataya
