Description of drawings
Figure 1A to Fig. 1 G shows the schematic diagram of the process of antenna manufacturing of the present invention;
Fig. 2 A and Fig. 2 B are antenna structure views of the present invention.
Embodiment
Figure 1A-Fig. 1 F shows in the antenna fabrication process of the present invention, and the antenna structure view of each step is described method for manufacturing antenna of the present invention in detail below in conjunction with Fig. 1.
Shown in Figure 1A, at first prepare a basal body structure spare 10, this basal body structure spare 10 can adopt traditional technology to make, and material can be selected for use such as ABS etc. and be fit to electroplate material with chemical plating, and its shape can customize as required.
Then, shown in Figure 1B, do not need to form coated resistance plating agent 15 on the outer surface of radio-frequency (RF) component figure at basal body structure spare 10, this resistance plating agent 15 can adopt for example resistance to plate printing ink etc.The scope of not coated resistance plating agent can be greater than the radio-frequency (RF) component figure, so that there are enough spaces to form antenna radio-frequency (RF) component figure.
Then, shown in Fig. 1 C.Fig. 1 C shows the partial enlarged drawing of this substrate structural member 10.In this step, use nickel chemical plating technology, basal body structure spare 10 is carried out chemical nickel plating.Because in the step of Figure 1B, be coated with resistance plating agent 15 at basal body structure spare 10 part surfaces, therefore, can be coated with chemical Ni-plating layer on the surface that scribbles resistance plating agent 15 of basal body structure spare 10, and on the surface of its not coated resistance plating agent, form chemical Ni-plating layer 20.Though be that nickel chemical plating technology is an example in the present embodiment, be appreciated that other chemical plating metal technology can be used here, for example copper facing etc.Should not be limited to nickel chemical plating technology in the method for the present invention, can use other suitable chemical plating metal technology yet.
Then, the chemical Ni-plating layer 20 that forms on this basal body structure 10 is carved,, removed unnecessary chemical Ni-plating layer 20 from basal body structure 10 surfaces according to needed antenna pattern, remaining chemical Ni-plating layer is antenna radio-frequency (RF) component figure 40, sees also Fig. 1 D.In the present embodiment, engraving can adopt laser-engraving technique.
See also Fig. 1 E again, after having formed antenna radio-frequency (RF) component figure 40, adopt electroplating technology, this antenna pattern 40 is carried out copper electroplate, form copper electroplating layer 50 on antenna pattern, Fig. 1 F is the decomposing schematic representation of Fig. 1 E.This technology should not be limited to electro-coppering, can use other coats of metal such as silver-plated etc. yet.
At last, shown in Fig. 1 G, on the antenna pattern of electro-coppering 50, re-plating nickel 60 plays the effect of protection to the antenna radio-frequency (RF) component.Here should not only limit to nickel plating, other have coating such as gold-plated this technology that also is fit to of protective effect.Here need to prove that this electronickelling 60 is optional steps.
Describe the antenna structure that obtains based on above-mentioned steps manufacturing of the present invention below with reference to Fig. 2 A and Fig. 2 B, wherein Fig. 2 A shows the schematic diagram of antenna structure of the present invention; Fig. 2 B is the profile of the antenna structure of Fig. 2 A.Antenna structure provided by the invention comprises two parts: basal body structure spare 10 and antenna radio-frequency (RF) component 70.Antenna radio-frequency (RF) component 70 is positioned on the basal body structure spare 10, and it comprises chemical Ni-plating layer 20 and electro-coppering 50, electronickelling (layer) 60.According to adopting different chemical plating metal technology in the manufacturing process, this chemical Ni-plating layer 20 can be other chemical plating metal layer.Equally, electro-coppering, nickel dam also can adopt other electroplated metal layer.
As mentioned above, method for manufacturing antenna of the present invention and antenna structure thereof are compared with traditional technology, have following advantage:
Owing in technical process, adopt metallising process to form radio-frequency (RF) component, eliminated the gap between radio-frequency (RF) component and all elements, and then eliminated the adverse effect of gap distortion antenna RF performance stability.And this method helps the adjustment and the change of radio-frequency performance, again owing to have only one deck plastics, therefore with by electrodepositable and not the antenna formed of two kinds of materials of electrodepositable compare, can provide than large space for radio-frequency performance design.Another important advantage is to form various antenna patterns as required on the three-dimensional geometry matrix of complexity.
