Claims

[Claims for Utility Model Registration] At the front end of the slot waveguide, with a space in front of the front end in between,
A pair of dielectric plates whose thickness is sufficiently thin compared to the wavelength used is provided protrudingly, and electromagnetic waves transmitted through the vicinity of the base of the dielectric plates and emitted are reflected to the outside of the pair of dielectric plates. In a slot array antenna device comprising a reflector, the pair of dielectric plates are arranged such that at least one of the outward facing surface or the inward facing surface of the dielectric plate is in contact with the corresponding one of the other dielectric plate. and a vertical polarization suppressing element is installed near the front end of the slot waveguide between the pair of dielectric plates.
