Embodiment

[0022] Such as Figure 1-5 As shown, this embodiment discloses a four-ridge pyramid horn antenna, which includes a rectangular waveguide 1 , a pyramid horn 2 , a feed port 3 , two waveguide section ridges 4 and four horn section ridges 5 .

[0023] Wherein, the rectangular waveguide 1 has a cuboid structure, the length of the wide side of the opening end is 3 inches, the length of the narrow side is 2 inches, and the length of the rectangular waveguide is 1 inch. see image 3 In the orientation shown, the pyramid horn 2 is located below the rectangular waveguide 1 , together forming a pyramid horn antenna, and the feeding port 3 is located above the rectangular waveguide 1 .

[0024] Specifically, see figure 1 , the pyramid horn 2 has a hollow square truss structure and is made of metal. The length of the wide side of the diameter is 6.445 inches, the length of the narrow side of the diameter is 5.063 inches, and the length of the pyramid horn 2 is 10.743 inches. One end of...

Abstract

The invention discloses a four-ridge pyramidal horn antenna, which comprises a rectangular waveguide, a pyramidal horn and a feeding port; the rectangular waveguide is a hollow structure, one end is connected with the feeding port, and the other end is connected with the pyramidal horn; The pyramid horn is a hollow quadrangular truss, including a waveguide section ridge and a horn section ridge; the waveguide section ridge is arranged inside the rectangular waveguide, one end is in contact with the feed port, and the other end is in contact with the horn section ridge; the horn section ridge includes There are two sets of upper and lower sets, each of which is arranged in the shape of a "herringbone" in the two wide walls of the pyramid horn. By optimizing various parameters of the ridge, the invention can realize more uniform field distribution than the traditional horn, thereby realizing higher gain.

Description

technical field [0001] The invention relates to a horn antenna, in particular to a four-ridge pyramid horn antenna. Background technique [0002] The basic form of the horn antenna is formed by gradually expanding the opening surface of the rectangular waveguide and the circular waveguide, which improves the matching between the waveguide and the free space, and makes the reflection coefficient in the waveguide small. The horn antenna has the advantages of simple structure and easy control of the pattern, and is often used as a standard antenna in antenna measurement; a unit antenna of a phased array; a feed source of a large radio telescope, etc. [0003] The existing horn antenna has the defects of uneven field distribution and low gain. Contents of the invention [0004] Purpose of the invention: In order to overcome the defects of the prior art, the present invention provides a four-ridge pyramidal horn antenna, which has the characteristics of uniform field distribut...
