Title:
WAVEGUIDE DEVICE, AND ANTENNA DEVICE INCLUDING THE WAVEGUIDE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/207796
Kind Code:
A1
Abstract:
A waveguide device is for use in propagating an electromagnetic wave of a band having a shortest wavelength λm in free space. The waveguide device includes: a first electrically conductive member having an electrically conductive surface and a first throughhole; a second electrically conductive member including a plurality of electrically conductive rods and having a second throughhole which overlaps the first throughhole as viewed along an axial direction of the first throughhole; and a pair of electrically-conductive waveguiding walls positioned so that at least a portion of a space between the first throughhole and the second throughhole is interposed therebetween. The pair of waveguiding walls are surrounded by the plurality of electrically conductive rods, and allow an electromagnetic wave to propagate between the first throughhole and the second throughhole. The pair of waveguiding walls each have a height which is less than λm/2.
