WAVEGUIDE
Document Type and Number:
WIPO Patent Application WO/2023/042466
Kind Code:
A1
Abstract:
This waveguide comprises: a first multilayered board in which a first dielectric layer and a plurality of first conductive layers the latter of which has a first opening are stacked; a first through via group in which a plurality of first through vias for electrically connecting the first conductive layers are aligned, in an in-plane direction of the first multilayered board, at intervals that are equal to or less than the one-half wavelength of an electromagnetic wave that is to be caused to propagate through the waveguide; and a second through via group in which a plurality of second through vias for electrically connecting the first conductive layers are aligned at said intervals in the in-plane direction. The waveguide does not have any through vias other than the plurality of first through vias and the plurality of second through vias. The first through via group and the second through via group are arranged, in the in-plane direction, in a direction orthogonal to the direction of the electric field of signals propagating in the thickness direction of the first multilayered board and are opposed to each other with the first opening therebetween.
