Claims

[Claims for Utility Model Registration] A pair of dielectric plates protruding in front of the slotted waveguide, sandwiching a space in front of the slot waveguide, and having a thickness sufficiently thin compared to the wavelength of the electromagnetic waves used, and A slot-shaped device is constructed by providing a reflector on the outside of a pair of dielectric plates to reflect electromagnetic waves transmitted through the vicinity of the base of the dielectric plates and then emitted. In the array antenna device, ribs with a thickness sufficiently thin compared to the wavelength of the electromagnetic waves used are provided at the tips of the pair of dielectric plates and on the outside of the dielectric plates from the tips of the dielectric plates to the opening of the reflector plate. It consists of a plurality of ribs installed at appropriate intervals, and all or some of the ribs are provided with their lower ends extending and hanging down, and the extended hanging portions of the ribs are connected directly or with connecting members. A slot array antenna device characterized in that it is configured to be attached to a pedestal via.
