Line part.Coaxial ridge waveguide conversion section is coaxial fitting, coaxial ridge waveguide conversion section along direction of an electric field respectively with left ridge 3,
Right ridge 4 makes electrical contact with, and ridge curved portion terminates at the start-up portion that loudspeaker cavity opens, and the start-up portion that loudspeaker cavity opens is square
Shape and the length of the rectangle are 2 times of width.In the technical program, coaxial ridge waveguide conversion section selects 50 Ω end such as
SMA, N-type etc., but should be noted that inner wire wants long enough, to be deep into corresponding ridge and to ensure electrical contact, together
The inner wire outer wall of axle should close proximity to ridge terminal.Additionally, it is also contemplated that in the loudspeaker cavity 2 increase dielectric material 5 with
Change the wavelength in pipe of main mould and higher mode in loudspeaker, and then adjust the phase when electromagnetic wave of different mode reaches bell mouth surface
Position relation, makes the field distribution in mouthful face reach perfect condition.
From above-described embodiment as can be seen that advantage of the present utility model is：
Have the advantages that small volume, efficiency high, compact conformation, longitudinal size are short.
Specific embodiment of the utility model is described in detail above, but the utility model is not restricted to the above
The specific embodiment of description, it is intended only as example.To those skilled in the art, any equivalent modifications and substitute also all
Among category of the present utility model.Therefore, the impartial conversion made in the case where not departing from spirit and scope of the present utility model
And modification, it should all cover in the range of the utility model.
