Abstract
The present application discloses a horn antenna, including a frequency selective surface (FSS), a connection structure, and a waveguide tube. The connection structure includes a first dielectric slab, a second dielectric slab, and a dielectric wall, which jointly form a hollow structure. A first surface of the first dielectric slab is a hyperboloid whose surface is protruding, a second surface of the first dielectric slab is connected to the dielectric wall. The dielectric wall has a tubular structure, a first surface of the dielectric wall is covered by the first dielectric slab, a second surface of the dielectric wall is covered by the second dielectric slab. There is a hole at a middle position of the second dielectric slab. The FSS covers the first surface of the first dielectric slab. A part of the waveguide tube is inserted into the hole of the second dielectric slab.
