Document Type and Number:
WIPO Patent Application WO/2018/064835
Kind Code:
A1
Abstract:
Disclosed in the present invention is a horn antenna, comprising: a frequency selection surface (FSS), a connection structure and a waveguide tube; the connection structure comprises a first medium plate, a second medium plate and a medium wall, a first surface of the first medium plate being a convex-surface hyperboloid, and a second surface being connected to the medium wall, wherein the distance between the two surfaces is the thickness of the first medium plate; the medium wall has a cylindrical structure, a first surface of the medium wall being covered by the first medium plate, and a second surface of the medium wall being covered by the second medium plate, wherein the distance between the two surfaces is the height of the medium wall; the central position of the second medium plate is provided with a hole; the medium wall, the first medium plate and the second medium plate jointly form a hollow structure; the FSS covers the first surface of the first medium plate; and a part of the waveguide tube is inserted into the hole of the second medium plate. The horn antenna disclosed in the present invention may reduce the height of a sidelobe of a light beam passing through the FSS, which improves the directivity of the antenna; at the same time, the present invention has higher radiation efficiency.
