Abstract
The invention provides a method for manufacturing antenna module group through laser carving, which includes steps: metal material (for example, silver, copper etc.) is attached to substrate by using spraying method, then metal material is refitted to accomplish antenna shape through laser carving. Thereby, shape and sculpt of antenna are not limited, and can be manufactured on non-plane substrate, further can reach effect of reducing whole antenna module group.
Description
Technical field
The present invention relates to a kind of manufacture method of antenna modules, directly rebuild metal material accompanying on the substrate to finish the manufacture method that antenna is shaped by laser engraving in particular to a kind of.
Background technology
Because the mobile communication technology development fast, makes that the application of portable type electronic product is more popular, for example mobile phone, notebook computer etc.These portable type electronic products are in order to meet portable requirement, trend towards to the miniaturization development always, and the space that makes inside accommodate element is seen more and dwindled.In order to comply with this trend, the many at present plate type antennas that used of antenna.
When traditional this type of plate type antenna of processing and manufacturing, as shown in Figure 1, is antenna 1 with metal material (for example copper) punch forming earlier, and then it is fitted on the plastic plate 2, thereby constitute an antenna module.Because the antenna 1 of metal material is by stamped, and precision is not enough in this case, therefore can not make undersized antenna, make the traditional antenna assembly must occupy the certain space of portable type electronic product.
Have again,, therefore make antenna pattern be constrained to tabular because the antenna 1 of metal material is by stamping forming, can only fit on the plastic plate 2, can't fit on the on-plane surface plastic plate, this is another bottleneck on the traditional antenna assembly is made, and remains to be improved.
Abideing by Patent Cooperation Treaty (Patent Cooperation Treaty, PCT) case of Ti Jiaoing number is PCT/IL2005/000611, international open day is on December 22nd, 2005, name is called in the international patent application formerly of " Three DimensionalAntennas Formed Using Wet Conductive Materials and Methods for Productionthereof (utilizing the dimensional antenna and the manufacture method thereof of wet conductor moulding) ", provided a kind of method for manufacturing antenna, this method provides the substrate with at least one three-dimensional surface, and to this at least one three-dimensional surface utilization conductor coating, by on a surface, forming antenna at least, and give and be applied to antenna on the substrate with three-dimensional surface a kind of comprising by the conductor coating.Should first to file by reference integral body incorporate this paper into.
Owing to should utilize conductor coating (Conductive Coating) technology to make three-dimensional antenna in first to file, but the demand of wideband and densification makes that the pattern of antenna is increasingly sophisticated, if therefore rely on the conductor coating technique merely, be to realize required antenna pattern.
Summary of the invention
The present invention is directed to the shortcoming that the classic flat-plate antenna module is made, a kind of brand-new method for manufacturing antenna is provided, the method comprising the steps of: substrate is provided; By spraying method with metal material attached on the described substrate and by laser engraving this metal material being rebuild to finish antenna pattern.Wherein the material of substrate can be plastics, pottery, paper or magnadure etc., or belongs to the some of portable type electronic product, like this, makes entire antenna no longer include spatial limitation, to meet the requirement of portable type electronic product densification; And because antenna pattern is finished by laser engraving, therefore make that antenna can be the shape of any complexity or densification, have the utilization of antenna manufacturing comparatively widely scope.
Simultaneously, therefore the present invention has high precision, so can be fit to make the different antenna of size dimension because antenna is finished antenna pattern by the laser engraving trimming.
Have, the present invention finishes antenna pattern by laser engraving after spray metal electric conducting material or the rough antenna pattern again on substrate again, therefore makes substrate can right and wrong flat, arc for example, even also can be three-dimensional 3D shape.
In addition, manufacture method of the present invention also can be applied in and make match circuit on the substrate, and is applied in the surface mount technology (SMT) and is used for solder(ing) paste is arranged on the printed circuit board (PCB).
Hereinafter, the embodiment shown in reference to the accompanying drawings introduces manufacture method step of the present invention and effect in detail.

Fig. 5 B: the antenna that is method manufacturing of the present invention is gain (gain) figure of 880MHz in the horizontal plane frequency.
Embodiment
With reference to Fig. 2, manufacturing process of the present invention comprises step:
By spraying method with metal material attached on the described substrate 20, and
By laser engraving this metal material is rebuild to finish the shape of antenna 10.
With reference to Fig. 3, show the antenna of making according to method of the present invention, this antenna is to make like this: by spraying method with metal material attached on the substrate 20, and then rebuild the shape of finishing antenna 10 by laser engraving.Wherein spraying method can be methods such as spraying plating, immersion plating, coating or plating, and the conductive metallic material that is attached on the substrate 20 can be copper, silver etc.
The material of substrate 20 can be plastics, pottery, paper or magnadure etc., also can be any parts such as the shell of portable type electronic product or internal circuit board.Certainly, this substrate 20 is the plane not necessarily, also can be on-plane surface, cambered surface, even three-dimensional 3D shape for example.
With reference to Fig. 4 A, Fig. 4 B and Fig. 5 A, Fig. 5 B, make (as shown in Figure 1) and the experiment contrast of the antenna of the same shape of (as shown in Figure 3) of making according to method of the present invention according to traditional process for stamping shown in these figure.
Fig. 4 A is voltage standing wave ratio (VSWR) figure of the antenna of traditional process for stamping manufacturing, and Fig. 4 B is voltage standing wave ratio (VSWR) figure of the antenna of method manufacturing of the present invention; As can be seen from the figure, these two antennas performance aspect voltage standing wave ratio is very approaching.Fig. 5 A is gain (gain) figure of antenna on the frequency level face of 880MHz that traditional process for stamping is made, and Fig. 5 B is gain (gain) figure of antenna on the frequency level face of 880MHz of method manufacturing of the present invention, as can be seen from the figure, both maximum gains and average gain are also close.Therefore, the antenna that produces of method of the present invention has practicality.
Have, laser engraving manufacture method of the present invention except being applied to antenna, also can being applied in and making match circuit on the antenna substrate again, for example earlier copper is sprayed on the substrate, and then carries out laser engraving and finish match circuit; Certainly, the present invention also can be used in the surface mount technology (SMT) and be used for solder(ing) paste is arranged on the printed circuit board (PCB).
