Document Type and Number:
WIPO Patent Application WO/2016/111107

Abstract:
A first dielectric plate and a horn-type emitter which faces in an end-fire direction are formed. A first cavity is formed in a second dielectric plate which is overlaid on the first dielectric plate. The first cavity is disposed in a position that partially overlaps the horn-type emitter, the first cavity has an opening portion which faces in the same direction as the horn-type emitter, and the first cavity is coupled electromagnetically to the horn-type emitter. The horn-type emitter includes first and second conductor films disposed on an upper surface and a lower surface of the first dielectric plate, and a first post wall. The second conductor film is interposed between the first dielectric plate and the second dielectric plate. The first cavity includes a third conductor film disposed on the second dielectric plate, and a second post wall. Provided is a horn antenna having a structure suitable for bandwidth broadening.
