摘要： The present application discloses a coaxial dual-band antenna, including a waveguide tube, a ring groove, a high frequency feed, and a dielectric ring. The high frequency feed and the dielectric ring have a same axis with the waveguide tube. The waveguide tube has a tubular structure, and is configured to transmit a first electromagnetic wave, the ring groove whose opening direction is the same as an output direction of the first electromagnetic wave is on a wall of the waveguide tube. The high frequency feed is located in the waveguide tube. The dielectric ring is filled between the waveguide tube and the high frequency feed, and has a multi-layer structure. The area sizes of planes that are at layers of the dielectric ring and that are perpendicular to the axis alternately change, and a height of the dielectric ring is less than a height of the waveguide tube.

摘要： 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.
