Specific implementation mode
With reference to specific embodiment, the present invention is described in further detail, it is described be explanation of the invention and
It is not to limit.
As shown in Figure 1, the electromagnetic horn disclosed by the invention with inserted sheet includes：Feed waveguide 2, waveguide transmission section 3, loudspeaker
4, inserted sheets of radial chamber and pedestal 1.The slot 5 (i.e. gap in figure) that loudspeaker radiation chamber 4 is stayed in figure is to be reserved to inserted sheet
Position, for the addition of inserted sheet.
As shown in Fig. 2, it is FBP100 (GBT11449.2-1989) that pedestal, which uses ring flange, specification, when processing, can integrally add
Work, also can be with antenna horn main body separate machined, welding forming.There are 4 through-holes, a diameter of 4.17mm of through-hole on ring flange.
Pedestal 1 is connected with 2 rear end of feed waveguide, and 2 rear end of feed waveguide is fixed on the rear end of band transmission section 3.
In the present embodiment, transmission main mould is TE10 moulds, and 2 rear end of feed waveguide is national standard waveguide BJ100, caliber size
22.86mm×10.16mm.The caliber size of waveguide transmission section 3 is 48.26mm × 10.16mm.In waveguide segment, we utilize mouth face
The thought of segmentation designs a waveguiding structure being divided into two, and recycles the separation of variable to be asked according to Helmholtz equation
It solves, the waveguiding structure of the one-to-two optimized after excellent ginseng.
The loudspeaker radiation chamber 4 is connected with waveguide transmission section 3, expands the loudspeaker day that mouth face can be obtained a double outlets
Line.Caliber size is different from waveguide transmission section 3, is increased on the direction of the faces E, and the faces H are consistent on direction, and caliber size is
48.26mm×42.44mm.Inserted sheet is connected with loudspeaker radiation chamber 4 and waveguide transmission section 3, and the thickness of inserted sheet is 0.5mm.
As shown in figure 3,6 be the section shape outside loudspeaker, 7 be the section shape of inserted sheet.Insert section is embedded in waveguide segment,
Rest part is divided into two parts, waveguide in loudspeaker radiation intracavitary, by the electromagnetic wave that waveguide segment transmits in loudspeaker radiation intracavitary
Section axial length is 29.50mm, and the axial length of inserted sheet is 43.50mm, and loudspeaker entirety axial length is 73mm.
Antenna horn material of main part is copper, and surface of internal cavity roughness is integrally not more than 1.6.
Each junction rounding off of surface of internal cavity；Silver-plated process, 1 μm of silver plating thicknesses.
Advantages of the present invention can be further illustrated by following emulation：
After carrying out modeling and simulation processing to above-mentioned antenna using HFSS, gain contrast is as shown in figure 4, the faces E, the faces H are imitated
