The antenna reflection face of the laminar film plastic satellite antenna adopts a transverse parabola structural design, a back support is flexible in rotating, the offset antenna adopts laminar film plastic materials, and the laminar film plastic satellite antenna has the advantages of corrosion resistance, small side lobes, high energy efficiency and low highlight reflection interference and can be widely applied to various satellite antenna receiving fields.
Description
Technical field
The utility model relates to a kind of antenna, is specifically related to a kind of laminar film plastics satellite antenna.
Background technology
In recent years; Cable TV has attracted countless spectators with its abundant program and the image of high-quality, and the satellite programming signal is the star turn source that many wired stations receive, and has received satellite programming; Image with high-quality is spectator services, becomes the task of many station most important things naturally.According to the relative position of the feed and the surface of emission, satellite antenna is divided into three kinds on front feed antenna, rear feed antenna and offset-fed antenna usually.Traditional offset-fed antenna does not have subreflector, and mostly structure is vertical parabolic shape, and the reinforcement at its back is radial, and simultaneously the smooth surface structure is taked in the front, causes that the light reflection interference is big, secondary lobe is high, the fragile defective such as serious of amplifying circuit.
Satellite earth antenna is in satellite receiving system foremost, and the quality of its structural behaviour directly affects the quality of received signal quality, especially under the abominable situation of environment, uses.Therefore, need the improvement of satellite antenna being carried out structure badly, to adapt to the needs that satellite-signal receives.
Summary of the invention
The utility model overcomes the deficiency of prior art; A kind of laminar film plastics satellite antenna is provided; Through the structure of antenna reflective face and antenna back frame is improved; With the material of sheet molding compound, reach corrosion-resistant, efficiency is high, secondary lobe is few, the antenna surface precision is high, reflection interference is little, rotate flexible characteristic as the offset-fed antenna.
The technical scheme of the utility model is following: a kind of laminar film plastics satellite antenna; Structure is made up of supporting construction, orientation clamping plate, antenna reflective face, pitching clamping plate, reinforcement, antenna base and offset-fed antenna; Said antenna reflective face links to each other with supporting construction with the orientation clamping plate through the pitching clamping plate, and the orientation clamping plate are positioned at the back of antenna reflective face, and the back of antenna reflective face is furnished with reinforcement; Antenna base is positioned at lowermost end, links to each other with supporting construction.
Said offset-fed antenna adopts the sheet molding compound material to process, and said sheet molding compound is for adopting the sheet material compression molding, and corrosion resistance is strong, and ageing resistance is strong.
Said antenna reflective face adopts horizontal parabolical structural design, and the X-direction area is increased, and helps reducing secondary lobe, improves efficiency, and reflecting surface adopts the orange peel design simultaneously, avoids emergency light reflex to disturb or damage amplifying circuit.
Said reinforcement is the graticule distribution form that intersects anyhow, can guarantee the antenna surface precision.
But said orientation clamping plate are the circular design of supporting antenna face rotation, help receiving satellite signal.
Said pitching clamping plate adopt U type structure and orientation clamping plate combine to make antenna surface not only can left rotation and right rotation, rotate up and down, can also on the XYZ axle, do three-dimensional the rotation, improve many stars receiving feature.
The attainable beneficial effect of the utility model is:
1, antenna reflective face replaces traditional vertical parabola mechamism and smooth surface design, changes horizontal parabola laminated structure into and adopts the orange peel design, helps reducing secondary lobe, improves efficiency, avoids emergency light reflex to disturb;
2, strong muscle becomes the graticule form of intersecting anyhow, antenna surface precision height with traditional radial different;
3, antenna back frame adopts the design of orientation clamping plate and pitching clamping plate to make antenna surface can on the XYZ axle, do three-dimensional the rotation, improves many stars receiving feature;
4, with the material of sheet molding compound as the offset-fed antenna, corrosion resistance is strong, and ageing resistance is excellent, and moulding is prone to, and can be widely used in each satellite antenna and receive the field.
Description of drawings
Fig. 1 is the end view of the utility model.
Fig. 2 is the schematic rear view of the utility model.
Wherein 1 is supporting construction, and 2 are the pitching clamping plate, and 3 is the orientation clamping plate, and 4 is reinforcement, and 5 is antenna reflective face, and 6 is antenna base.
Embodiment
Be described further below in conjunction with the embodiment of accompanying drawing the utility model:
As shown in Figure 1; A kind of laminar film plastics satellite antenna; Antenna reflective face (5) links to each other with supporting construction (1) with orientation clamping plate (3) through pitching clamping plate (2), and orientation clamping plate (3) are positioned at the back of antenna reflective face (5), and antenna reflective face (5) back is furnished with reinforcement (4); Antenna base (6) is positioned at lowermost end, links to each other with supporting construction (1).
The embodiment of the utility model is following:
A kind of laminar film plastics satellite antenna; When receiving satellite signal, concave upright with antenna reflective face (5) is because the parabola receiving plane of transversary design; The X-direction area increases; Make that reception signal area is wide, can reduce the generation of secondary lobe, the reinforcement (4) that the graticule that its back intersects anyhow distributes has guaranteed the precision of reflecting surface (5) face type.
If think the convert signals receive direction, direct rotational orientation clamping plate (3), thereby the rotation of drive antenna reflective face (5); The location of carrying out all directions receives; For with offset-fed antenna better fit, adjustable antenna pitching clamping plate (2) make antenna reflective face (5) on the XYZ axle, do three-dimensional the rotation; Can improve many stars receiving feature, make signal receive that approach is wideer, signal is more smooth and easy.
The utility model owing to adopt the material of sheet molding compound as the offset-fed antenna, makes that the offset-fed antenna corrosion resistance of its more traditional material is stronger at low temperature, when moist environment uses down, and is littler to the influence of signal reception.
