Japan, March 5 -- WASEDA UNIV has got intellectual property rights for 'WAVEGUIDE, METHOD OF MANUFACTURING WAVEGUIDE AND ANTENNA.' Other related details are as follows:
Application Number: JP,2022-208578
Category (FI): H01P11/00,101,H01P5/02,601
Stage: PROBLEM TO BE SOLVED: To achieve miniaturization of a waveguide while favorably maintaining frequency characteristics of the waveguide.SOLUTION: A waveguide 1 includes a first conductor plate 11 and a second conductor plate 12 in contact with the first conductor plate 11. The first conductor plate 11 includes: a groove portion 111 that has a rectangular cross section and that is formed parallel to a first main surface, which is a flat surface of the first conductor plate 11 on the second conductor plate 12 side, such that the longitudinal direction thereof becomes a first direction; and a first vertical tube portion 112 formed in a direction away from the second conductor plate 12 in a second direction orthogonal to the first direction and the first main surface, with a branch position in the groove portion 111 as a starting point. The second conductor plate 12 includes a reflection portion 122 that is inserted into the groove portion 111 in a manner protruding from a second main surface, which is a flat surface of the second conductor plate 12 in contact with the first main surface, and has a reflection surface R that reflects a radio wave, propagated along the groove portion 111, toward the first vertical tube portion 112.SELECTED DRAWING: Figure 1 (Grant)
