Description
Technical field
The utility model relates to feedhorn technology field, is specially a kind of multimode corrugated horn.
Background technology
Reflector antenna is the antenna with high-gain, is therefore widely used at distance radio communication and radar system.And be applied to the feed of antenna system, adopt traditional corrugated horn, corrugated horn to have the voltinisms such as directional diagram are good, cross polarization level is low, double frequency matching properties is good more
Etc. advantage, in communication, radar, guidance, remote measurement, remote sensing, astronomy and television broadcasting etc., there is 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.But the processing for the corrugated horn of millimere-wave band especially short millimeter band encounters very large difficulty, particularly when required precision is very high, difficulty of processing is just more difficult, and processing cost also increases exponentially, and then causes rate of finished products low.
Therefore, for the problems referred to above, the utility model proposes a kind of new technical scheme.
Utility model content
The purpose of this utility model is to provide a kind of operating accuracy multimode corrugated horn high, easy to process.
The utility model is achieved through the following technical solutions:
A kind of multimode corrugated horn, comprise connect successively circular waveguide, become mould section A, become mould section B and radiant section, abrupt step is provided with between described circular waveguide end and change mould section A, between described change mould section A and change mould section B, bolt is installed, spring washer is provided with in described bolt, described change mould section A and change mould section B is stepped impedance type structure, and described radiant section is made up of some periodic corrugated structures linearly gradually opened.
Further, the groove both sides of described change mould section A are equipped with diaphragm.
Further, the groove width of described change mould section A is all different with the facewidth.
Further, the diaphragm width of the groove both sides of described change mould section A is all different with the degree of depth.
Further, the groove width in described radiant section each cycle is all identical with the facewidth.
Further, described radiant section is in gradually opening type horn structure.
The beneficial effects of the utility model are: the utility model matches by becoming film section A and becoming film section B, produce useful higher mode, improve precision, optimize radiance, this structure is combined by many parts simultaneously, ensure that by the machining accuracy in mechanical processing process, also reduce difficulty of processing, improve rate of finished products, and electrical property is excellent, improves the efficiency of reflector antenna.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of multimode corrugated horn of the utility model.
Wherein: 1, circular waveguide, 2, become film section A, 3, become film section B, 4, radiant section, 5, abrupt step, 6, diaphragm, 7, bolt, 8, spring washer, 9, become the A groove of film section, 10, become the A tooth of film section, 11, tooth, 12, groove.
Embodiment
Illustrate below in conjunction with accompanying drawing and the utility model is illustrated with doing a step.
A kind of multimode corrugated horn as shown in Figure 1, comprise the circular waveguide 1, change mould section A 2, change mould section B 3 and the radiant section 4 that connect successively, abrupt step 5 is provided with between circular waveguide 1 end and change mould section A 2, become mould section A 2 and become between mould section B 3 and bolt 7 is installed, spring washer 8 is provided with in bolt 7, becoming mould section A 2 and becoming mould section B 3 is stepped impedance type structure, and radiant section 4 is made up of some periodic corrugated structures linearly gradually opened.Groove 9 both sides becoming mould section A are equipped with diaphragm, become the wide and wide equal difference of tooth 10 of the groove 9 of mould section A, diaphragm 6 width becoming groove 9 both sides of mould section A is all different with the degree of depth, and the groove 12 in radiant section 4 each cycle is wide wide all identical with tooth 11, and radiant section 4 is in gradually opening type horn structure.
The utility model matches by becoming film section A and becoming film section B, produce useful higher mode, improve precision, optimize radiance, this structure is combined by many parts simultaneously, ensure that by the machining accuracy in mechanical processing process, also reduce difficulty of processing, improve rate of finished products, and electrical property is excellent, improves the efficiency of reflector antenna.
