The millimeter wave conical horn antenna can meet different irradiation angle requirements and has the characteristics of simple processing, low cost and convenient installation.
Description
Technical field
The utility model belongs to millimetre-wave radar and millimetre-wave attenuator technical field, particularly a kind of millimeter wave conical horn antenna of mechanical type translation-angle.
Background technology
Along with the application of millimeter-wave technology, communicating by letter of the radar of millimeter wave and millimeter wave also obtains darker research and development.Wherein the utilization of conical-horn antenna is more extensive, and it is little that this antenna has a volume, anti-vibration, and shock resistance, cost is low, easily the advantage such as processing.The conical-horn antenna that existing market is used is fixing bore and fixing aerial angle, because radar and its operating distance of communication equipment and beam angle are inversely proportional to, and at some application occasions, often require the narrow operating distance of beam angle far away, but also there are a lot of radars and communication equipment to require the beam angle of irradiation wide, meet different irradiating angles and can only change different antenna capable of adjusting angles, the antenna of wanting to change different angles can only be changed the shell of machinery equipment, this can be to applying unit in the time with all bring economically certain impact, radar or communication equipment be not in the situation that change inner and appearance, can be applicable to again the angle that remote narrow beam and in-plant broad beam angular illumination best approach are exactly the conversion antenna simultaneously.
The utility model content
The purpose of this utility model is to provide a kind of can meet different irradiating angles, and processes the millimeter wave conical horn antenna of mechanical type translation-angle simple, with low cost, easy for installation.
The technical solution that realizes the utility model purpose is:
A kind of millimeter wave conical horn antenna of mechanical type translation-angle, comprise millimeter wave conical horn antenna and N conical horn section ring flange, N >=1, millimeter wave conical horn antenna comprises the horn antenna ring flange connected successively, waveguide, benchmark loudspeaker section and benchmark loudspeaker section ring flange, conical horn section ring flange is connected with benchmark loudspeaker section ring flange, conical horn section ring flange, with the tapering of benchmark loudspeaker section bore, is arranged successively according to caliber size.
The utility model compared with prior art, its remarkable advantage:
(1) due to the conical horn section ring flange that a plurality of different bores are installed successively, therefore can adjust caliber size, meet different needs.
(2) of the present utility model simple in structure, be convenient to processing, use and change.
Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 5 is that the millimeter wave conical horn antenna of a kind of mechanical type translation-angle of the utility model embodiment has been dismantled a part of conical horn section ring flange and formed to obtain a new bore conical-horn antenna.
Embodiment
As Fig. 1, shown in Fig. 2 and Fig. 3: the millimeter wave conical horn antenna of a kind of mechanical type translation-angle of the utility model, comprise millimeter wave conical horn antenna and N conical horn section ring flange 5, N >=1, millimeter wave conical horn antenna comprises the horn antenna ring flange 1 connected successively, waveguide 2, benchmark loudspeaker section 3 and benchmark loudspeaker section ring flange 4, horn antenna ring flange 1 and waveguide 2 are one processing, conical horn section ring flange 5 is connected with benchmark loudspeaker section ring flange 4 by bolt, conical horn section ring flange 5 is with the tapering of benchmark loudspeaker section 3 bores, according to caliber size, arrange successively.
Circumferentially at four direction, be symmetrical arranged interior location hole 6 with radius D edge on conical horn section ring flange 5, with radius R, along circumferentially at four direction, being symmetrical arranged outside fix hole 7, wherein D is less than R.
In conjunction with Fig. 1:
Embodiment: the heavy caliber narrow beam angle millimeter wave conical horn antenna that is the utility model mechanical type translation-angle, it is by millimeter wave conical horn antenna and 11 millimeter wave conical horns that (the demand setting of bore as required) conical horn section ring flange 5 forms of small-bore broad beam angle, wherein, as shown in Figure 4, be an independently millimeter wave conical horn antenna of broad beam angle.This antenna material is selected LY12 duralumin or H62 brass, first need as requested to do the conical-horn antenna of how many bores, then carrying out segmentation roughing according to the design size of different bores, each segmented pieces couples together conical horn section ring flange 5 with screw and shop bolt by the order of caliber size.Before conical horn section ring flange 5 connects, two end faces of each section will carry out fine finishining, the depth of parallelism that requires each end face is 0.02mm, perpendicularity is 0.05mm, the tolerance of thickness is 0.1mm, add and must unify positioning datum man-hour, reduce clamping times, be conducive to like this guarantee the machining accuracy of antenna.Carry out accurate processing at upper lathe after connecting into an integral body, its inside of the processing request of whole antenna is there is no step and smooth conical horn, obvious gap is not seen in conical horn section ring flange 5 internal connections, the concentricity of inner circle and cylindrical is at 0.05mm, fineness ▽ 8, carrying out surface treatment while all reaching requirement, by a plurality of bores, different conical horn section ring flanges 5 is combined in and just forms a heavy caliber narrow beam angle millimeter wave conical horn antenna like this, as shown in Figure 5: as the antenna of which bore of needs just takes off top part from its end, stay the part of back, the part of back just forms a new bore conical-horn antenna like this, the epimere part of taking off from top to bottom by that analogy different end faces just becomes the conical-horn antenna of different bores.
Its circular cone caliber size of thickness difference of conical horn section ring flange 5 is also different, the angle of its antenna is also fully different, in the situation that the tapering of benchmark loudspeaker section 3 bores is identical, the thicker bore of thickness of conical horn section ring flange 5 is just larger, just less gain is higher for its aerial angle, otherwise aerial angle is the larger gain end more just, in like manner just more wide-angle is just less for more its bores of the quantity of conical horn section ring flange 5.Therefore, the thickness of single conical horn section ring flange 5 determines the span of gain, and reality can gain-crossover as required arranges the thickness of single conical horn section ring flange 5.
