Description
Technical field
The utility model relates to a kind of loudspeaker, particularly relates to a kind of corrugated horn.
Background technology
Corrugation loudspeaker feed source has the advantages such as the voltinisms such as directional diagram are good, cross polarization level is low, double frequency matching properties is good, in communication, radar, guidance, remote measurement, remote sensing, astronomy and television broadcasting etc., have boundless application prospect.
At present, the known feed for Satellite microwave remote sensing antenna system, the corrugated horn that many employings are traditional.Comprise and be transitioned into the ripple changeover portion of 1/4 wavelength groove depth and the corrugated radiation section of 1/4 wavelength groove depth gradually by 1/2 wavelength groove depth.Its shortcoming is: at millimeter wave or more high band, because loudspeaker size is less, the difficulty of processing of ripple changeover portion is very large, the circular waveguide radius of general 90GHz millimeter wave Feed Horn is 1.3 ~ 2mm, the ripple groove depth of corrugated horn throat is about 1.68mm(1/2 wavelength), this makes changeover portion be difficult to processing near the wave groove of horn throat, and the bad guarantee of size, adds and easily rupture man-hour.
Therefore, for solving the problem, spy provides a kind of new technical scheme.
Utility model content
The utility model provides a kind of corrugated horn.
The technical solution adopted in the utility model is:
A kind of corrugated horn, comprise the circular waveguide section, change film section and the corrugated radiation section that connect successively, be provided with abrupt step between described change film section end and corrugated radiation section, be provided with flange in corrugated radiation section outside, the linear half angle degree gradually opened of described corrugated radiation section is between 25-30 °.
The width of the groove of the ripple in each cycle of described corrugated radiation section is all identical.
The width of the tooth of the ripple in each cycle of described corrugated radiation section is all identical.
The beneficial effects of the utility model are: simple and reliable for structure, adopt half angle degree between 25-30 °, optimize the stability of loudspeaker, abrupt step is adopted to motivate higher mode, effectively can optimize the radiance of loudspeaker, this kind of corrugated horn is easy for installation simultaneously, meets the demand of various model.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, circular waveguide section, 2, become film section, 3, corrugated radiation section, 4, abrupt step, 5, flange, 6, groove, 7, tooth.
Embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to protection range of the present utility model.
A kind of corrugated horn as shown in Figure 1, comprise the circular waveguide section 1, change film section 2 and the corrugated radiation section 3 that connect successively, become between film section 2 end and corrugated radiation section 3 and be provided with abrupt step 4, in corrugated radiation section 3 outside, flange 5 is installed, the linear half angle degree gradually opened of corrugated radiation section 3 is between 25-30 °, the width of the groove 6 of the ripple in each cycle of corrugated radiation section 3 is all identical, and the width of the tooth 7 of the ripple in each cycle of corrugated radiation section 3 is all identical.
The beneficial effects of the utility model are: simple and reliable for structure, adopt half angle degree between 25-30 °, optimize the stability of loudspeaker, abrupt step is adopted to motivate higher mode, effectively can optimize the radiance of loudspeaker, this kind of corrugated horn is easy for installation simultaneously, meets the demand of various model.
The above; it is only preferred embodiment of the present utility model; not restriction the utility model being made to any other form, and any amendment done according to technical spirit of the present utility model or equivalent variations, still belong to the utility model scope required for protection.
