Below described preferred embodiments is elaborated: as shown in Figure 2, in described step a, described super material sheet material comprises at least one super material layer 20, each super material layer 20 comprises a medium substrate 22 and is attached to a plurality of artificial micro-structural 24 of described medium substrate 22, as being positioned at the pattern of the grid that is formed by dotted line among Fig. 2, described pattern only is an example of described artificial micro-structural 24, is not construed as limiting the invention.Each artificial micro-structural 24 is the plane with certain geometrical shape or stereochemical structures that the line segment by certain-length forms.Described a plurality of artificial micro-structural 24 can be attached to two surfaces relatively of described medium substrate 22, also can only be attached to arbitrary surface of described medium substrate 22.Generally, described a plurality of artificial micro-structurals 24 are periodically arranges, and also, described a plurality of artificial micro-structurals 24 are periodically to be arranged on the described medium substrate 22.Generally, medium substrate 22 parts at each artificial micro-structural 24 and place thereof are called a super material cell 26, thus, described super material layer 20 can be regarded as by a plurality of described super material cell 26 arrays and forms.The physical dimension of each super material cell 26 is relevant with the electromagnetic wavelength that passes described super material radome 10, is 1/10th of electromagnetic wavelength as its physical dimension.When described super material sheet material comprises a plurality of described super material layer 20, can allow a plurality of described super material layers 20 be superimposed and make by mechanical connection, welding, mode hot-forming or that other are bonding along the direction perpendicular to lamella.So, when making described super material sheet material:
A1. design a plurality of artificial micro-structurals.
A2. make described a plurality of artificial micro-structurals at medium substrate.
In described substep a1; electromagnetic environment according to the use occasion of described super material radome; it mainly is the operating frequency of considering its claimed antenna; use electromagnetic theory, and geometry, size and the arrangement mode of a plurality of artificial micro-structurals as described in designing as CST (by the pure electromagnetic field simulation software of German CST company product) etc. by computer analog software.Generally, we only design geometry and the size of an artificial micro-structural, and then are that sample copies and forms described a plurality of artificial micro-structurals with it.This shows that the geometry of described a plurality of artificial micro-structurals all is identical with size.But save design time and improve design efficiency like this.Certainly, if not for this purpose, the geometry of described a plurality of artificial micro-structurals and/or size fully can be inequality.
In described substep a2, in advance at one or both sides set metal forming such as the Copper Foil of described medium substrate, etch described a plurality of artificial micro-structural according to geometry, size and the arrangement mode of described a plurality of artificial micro-structurals of design and the control by computer program in described metal forming.Described medium substrate is made by thermoplastic, and described a plurality of artificial micro-structural is except can being made of copper, also can wait other metals or electric conducting materials such as graphite, carbon nano-tube to make by silver, tin indium oxide (ITO), also namely, the film of being made by above-mentioned electric conducting material in the one or both sides set of described medium substrate.Described a plurality of artificial micro-structural also can by electroplate, bore quarter, photoetching, electronics is carved or ion is carved mode is formed on the described medium substrate.
In the reality, the super material sheet material among the described step a makes by the etching copper-clad plate, when it comprises the super material layer of multilayer, can make by the multilayer copper-clad plate of pressing through etch processes.Super material sheet material 30 shown in Fig. 3 is roughly rounded, and its medium substrate is made by ABS, and artificial micro-structural is the metal micro structure that is made of copper cash, and is attached to two surfaces relatively of described medium substrate.
In described step b, described framework is made through suitable processing technology such as injection mo(u)lding, compression molding or machining by thermoplastic, supports described super material sheet material and can bear the heavy burden that the described super material radome 10 of outer bound pair applies as long as can play.Generally, for the ease of welding, described medium substrate and framework are by making with a kind of thermoplastic.If not for this purpose, described medium substrate and framework can have any thermoplastic to make respectively.The geometry of described framework can be decided according to actual conditions, as annular, cross, skeleton shape etc.An embodiment of described framework as shown in Figure 3, it is a circular frame 40 that matches with the edge contour of described super material sheet material 30, (be Acrylonitrile Butadiene Styrene by acrylonitrile-butadiene-styrene (ABS), be called for short ABS) make, comprise annulus portion 42 and by described annulus portion 42 surround and form uncovered 44, the cross section of described annulus portion 42 is roughly L-shaped.Described frame 40 can utilize the ABS raw material through an injection moulding or compression molding and make; Also can utilize the ABS raw material to make the similar semi-finished product that the circular shallow disc shape at the end is arranged earlier through injection moulding or compression molding, the method by machining cuts out described uncovered 44 in described half-finished bottom and makes again.
In described step c; place described super material sheet material on the described framework and cover described opening; and its edge contacts with the side of described framework; at this moment it is integrally welded with them to pass through modes such as ultra-sonic welded, laser welding, thereby is formed for protecting the super material radome 10 of antenna.Ultra-sonic welded can be used for the described super material sheet material made by any material and the combination between the framework, as between the resin, between resin and the metal and between other material.Certainly, ratio is easier to combination when making by same material (its fusing point should not greater than 350 ℃) for described super material sheet material and framework, and the super material radome of making 10 is also more firm.Contact position at described super material sheet material and framework also can arrange some fit structures, in order to form the super material radome 10 of watertight and airtight better performances.
The described super material sheet material that the material that laser welding is mainly used in melting by absorbing enough laser is made and the combination between the framework, be specially adapted to the combination between the diverse polymer in aspect such as structure, softening temperature and reinforcing material, and can select different laser equipments to weld according to the material for the manufacture of described super material sheet material and framework.For example, neodymium-doped yttrium-aluminum garnet synthetic crystal (Nd3+:YAG) and diode laser, the optical maser wavelength of its generation is about 1064nm, 800-1000nm respectively, is suitable for described super material sheet material and the framework made by the resin that contains particular fillers or pigment; And carbon dioxide (CO
2) laser, the optical maser wavelength of its generation is about 10600nm, although be absorbed easily, its penetrability is bad, is applicable to thinner described super material sheet material and the combination between the framework.Compare with ultra-sonic welded, laser welding can greatly reduce vibration stress and the thermal stress of described super material radome 10, slows down its aging speed.
Described super material sheet material 30 and the frame 40 made by ABS shown in Fig. 3 are made described super material radome 10 by the method for ultra-sonic welded, because the intensity of its weld is close to the intensity of described super material radome 10 itself, thereby make integrated super material radome 10.
For globality and its aesthetic property of raising that keeps described super material radome outward appearance; can be armor coated at the surfaces externally and internally of described super material radome; described protective layer can be made by any existing protective coating that is used in the radome surface; should have good wave penetrate capability, anti-season, strong adhesion; as polyurethane, fluororesin, fluorocarbon resin etc., and the weld of described super material radome modified.
