Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0024] Such as figure 1 As shown, the horn antenna with a blade disclosed in the present invention includes: a feeding waveguide 2 , a waveguide transmission section 3 , a horn radiation cavity 4 , a blade and a base 1 . The slot 5 (that is, the gap in the figure) reserved by the horn radiation cavity 4 in the figure is a reserved position for the insertion piece, which can be used for adding the insertion piece.

[0025] Such as figure 2 As shown, the base adopts a flange, and the specification is FBP100 (GBT11449.2-1989). During processing, it can be processed as a whole, or it can be processed separately from the main body of the antenna horn, and welded to form. There are 4 through holes on the flange, and the diameter of the through holes is 4.17mm. The base 1 is connected to the rea...

Abstract

The invention discloses a horn antenna with an insertion sheet. The antenna comprises a base. The base is connected with the back end of a feeding waveguide. The front end of the feeding waveguide isconnected with the back end of a waveguide transmission segment. The front end of the waveguide transmission segment is connected with the horn antenna. An insertion sheet is embedded in the horn antenna. One part of the insertion sheet is embedded in the waveguide segment and the other parts are arranged in a horn radiation cavity, so electromagnetic waves transmitted by the waveguide transmission segment are divided into two parts in the horn radiation cavity. According to the invention, by introducing the insertion sheet, compared with a common horn antenna, the gain is improved to some extent; the directivity of the H face is improved; the horn antenna of the E face is characterized by high gain and good direction; and the horn antenna is simple in structure and easy to process.

Description

technical field [0001] The invention belongs to the technical field of microwave band antenna equipment, and in particular relates to a horn antenna with inserts. Background technique [0002] The horn antenna is a widely used microwave antenna. Its advantages are simple structure, wide frequency band, large power capacity, easy adjustment and use. As a kind of horn antenna, the pyramid horn has high gain, wide frequency band, and low side lobe. Features, so that it has important application value in electronic countermeasures, radar and other fields. [0003] However, there are two main problems in the existing horn antenna. First, the gain is low; second, the directivity is general, and the design of the horn in the prior art cannot solve these two problems. Contents of the invention [0004] In order to overcome the above-mentioned defects in the prior art, the object of the present invention is to provide a horn antenna with a patch, which can increase the gain and im...
