Title:
DIELECTRIC FILTER, ARRAY ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/053972
Kind Code:
A1
Abstract:
The purpose of the present invention is to obtain a dielectric filter that is small and suitable for a laminated structure. The dielectric filter is configured using: a dielectric waveguide formed from a conductor pattern and vias in a lamination direction within a multilayer dielectric substrate; two strip lines formed in a planar direction of the multilayer dielectric substrate; and two strip line-waveguide converters that perform transmission line conversion between the dielectric waveguide and each strip line. By doing this, it is possible to provide the dielectric filter for which the surface area occupied in the planar direction of the multilayer dielectric substrate is suppressed.
