Description
Technical field
The present invention relates to field of antenna, and in particular to a kind of novel 3mm wave band antenna film coated plastic subreflector bracket.
Background technique
Reflector antenna is also known as " surface antenna ".The antenna of predetermined beams is formed using metal mirror.Its feed can be
Oscillator or layered transducer elements are also possible to loudspeaker or trumpet array.Reflecting surface can be one, can also be two.The former is known as " single reflection face
Antenna ", the latter are known as " dual reflector antenna ".There are commonly rotary parabolic surface antennas, cylindricality parabola antenna, incision paraboloid
Antenna, spherical-reflector antenna, horn reflector antenna, angular reflector antenna, Cassegrain antenna, deformation Cassegrain day
Line etc..
With the development of science and technology, the requirement for antenna tracking performance is higher and higher, and large-scale antenna is due to by gravity
The influence that deformation and wind are disturbed, the position of the subreflector of antenna and posture change in real time, to influence the acceptance of antenna
Energy.Currently, being typically based on an adjustment bracket to the adjustment of antenna subreflector strip hole is opened against four studs to adjust,
Or it is adjusted using hinge arrangement.But when carrying out the adjustment of antenna subreflector using above-mentioned adjustment mechanism, its structure is complicated
And Adjustment precision is lower.Bracket used is metal structure simultaneously, also can significantly influence the acceptance of reflector antenna
Energy.
Summary of the invention
The purpose of the present invention is to provide a kind of novel 3mm wave band antenna film coated plastic subreflector bracket, plastics platings
For film subreflector bracket using injection molding and antenna reflective face integral structure, left-hand thread may be either sealing day on surface antenna
Irdome, and can be reflecting surface support frame, leakproofness is enhanced, windage is improved, while avoiding blocking for support frame again, to drop
Low antenna side lobe, greatly reduces influence of the bracket to reflector antenna.
A kind of novel 3mm wave band antenna film coated plastic subreflector bracket, including subreflector, plastic stent and face day
Line, using tubaeform left-hand thread on surface antenna, the lower end of plastic stent is fixedly connected on surface antenna the plastic stent, described
The upper end of plastic stent is equipped with fossaperturate, and the subreflector is fixedly mounted in the fossaperturate of the upper end of plastic stent.
Preferably, the subreflector is biasing metal-coated membrane reflecting surface, and institute's plating metal is copper, silver or gold.
Preferably, the plastic stent material therefor is polyether-ether-ketone (PEEK) resin material.
Preferably, the plastic stent using injection molding and with the integrated structure of antenna subreflector.
The present invention has the advantages that structure is simple, using flexible, the film coated plastic subreflector bracket uses injection molding
With antenna reflective face integral structure, left-hand thread may be either encapsulated antenna cover on surface antenna, and can be reflecting surface support frame, increase
Strong leakproofness, improves windage, while avoiding blocking for support frame again, to reduce antenna side lobe, greatly reduces
Influence of the bracket to reflector antenna.
Detailed description of the invention
Fig. 1 is general structure schematic diagram of the invention；
Wherein, 1, good fortune reflecting surface, 2, plastic stent, 3, surface antenna
Specific embodiment
Embodiment one:
As shown in Figure 1, a kind of novel 3mm wave band antenna film coated plastic subreflector bracket, including subreflector 1, plastics
Bracket 2 and surface antenna 3, using tubaeform left-hand thread 3 on surface antenna, the lower end of plastic stent 2 is fixedly connected the plastic stent 2
On surface antenna 3, the upper end of the plastic stent 2 is equipped with fossaperturate, and the subreflector is fixedly mounted on the upper of plastic stent 2
In the fossaperturate at end.Plastic stent 2 may be either encapsulated antenna cover, and can be reflecting surface support frame, enhances leakproofness, improves
Windage, and avoid being originally blocking for metal supporting frames, to reduce antenna side lobe.
Embodiment two:
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
As shown in Figure 1, a kind of novel 3mm wave band antenna film coated plastic subreflector bracket, including subreflector 1, plastics
Bracket 2 and surface antenna 3, using tubaeform left-hand thread on surface antenna 3, the lower end of plastic stent 2 is fixedly connected the plastic stent 2
On surface antenna 3, the upper end of the plastic stent 2 is equipped with fossaperturate, and the subreflector 1 is fixedly mounted on plastic stent 2
In the fossaperturate of upper end.
The subreflector 1 is biasing metal-coated membrane reflecting surface, and institute's plating metal is copper, silver or gold.Realize subreflector
Function, and realize angle of lead while enhancing the electric conductivity and reflection electromagnetic wave intensity of reflecting surface.
2 material therefor of plastic stent is polyether-ether-ketone (PEEK) resin material.Both the damage in 3mm wave band had been reduced
Consumption, and it is able to satisfy high-intensitive impact.
The plastic stent 2 using injection molding and with surface antenna 3 and the integrated structure of subreflector 1.Quality is small, by force
Degree is high, meets special occasions requirement.
Specific embodiment and principle:
After producing plastic stent 2 using the technique of injection molding, subreflector 1 is first fixedly mounted on plastic stent 2
On, then plastic stent 2 is fixedly mounted on surface antenna 3, after installing, since plastic stent 2 is that tubaeform can play guarantor
Mask antenna 3 acts on, while plastic stent 2 plays supporting role well as the bracket of subreflector 1.
Based on above-mentioned, the configuration of the present invention is simple, using flexible, the film coated plastic subreflector bracket using injection molding with
Antenna reflective face integral structure, left-hand thread may be either encapsulated antenna cover on surface antenna, and can be reflecting surface support frame, enhancing
Leakproofness, improves windage, while avoiding blocking for support frame again, to reduce antenna side lobe, greatly reduces branch
Influence of the frame to reflector antenna.
As known by the technical knowledge, the present invention can pass through the embodiment party of other essence without departing from its spirit or essential feature
Case is realized.Therefore, embodiment disclosed above, in all respects are merely illustrative, not the only.Institute
