Abstract
The present invention relates to a mobile terminal and a manufacture method of an antenna system thereof. The mobile terminal comprises a housing having a holding space, a body arranged in the holding space and a circuit board. The mobile terminal further comprises an antenna system arranged on the surface, toward the holding space, of the housing. The antenna system includes a laser activation coating pasted on the surface, toward the holding the space, of a rear cover, and an antenna formed on the laser activation coating through the adoption of a LDS (laser direct structuring), wherein the antenna is electrically connected with the circuit board. Regardless of the adoption of any material, an antenna may be formed at the surface of the housing through the LDS as long as the laser activation coating is sprayed on the surface of the housing, and materials are not restricted, therefore the RF performance of the antenna may be maximized and the mobile terminal may be much thinner.
Description
[technical field]
The present invention relates to mobile communication equipment field, more particularly, relate to the manufacture method of a kind of mobile terminal and LDS antenna system thereof.
[background technology]
Along with mobile phone develops towards slimming, also more and more higher to the designing requirement of the antenna system of interior of mobile phone.
Laser direct structuring technique (LaserDirectStructuing) refers to the motion of the TRAJECTORY CONTROL laser utilizing computer according to conductive pattern, by laser projection on molded three-dimensional plastic device, within the time in a few second, activated circuit pattern.For the design and production of antenna for mobile phone, refer on shaping plastic stent, utilize laser technology on plastic stent, directly change plating and form metal antenna pattern.The material of this technology to support has many restrictions.Such as not all material is all applicable to LDS technology, the material usually adopted is PC and ABS material.But present phone housing is not only satisfied with plastic casing, the shell of the even glass of metal is popularized gradually, and LDS technology cannot on these materials straight forming antenna.And the support adopting PC and ABS material to make is placed on interior of mobile phone, be subject to the impact of periphery components and parts, the RF performance of antenna cannot maximize.
[summary of the invention]
The technical problem to be solved in the present invention is, for the above-mentioned defect of prior art, provides the manufacture method of a kind of mobile terminal and antenna system thereof.
The technical solution adopted for the present invention to solve the technical problems is: construct a kind of mobile terminal, it comprise there is accommodation space housing, be located at body in described accommodation space and circuit board, this mobile terminal also comprises is located at described housing towards the antenna system on the surface of described accommodation space, described antenna system comprises and is covered on described bonnet towards the laser activation coating on described receiving space surface and adopt LDS technology to take shape in antenna in described laser activation coating, and described antenna is electrically connected with described circuit board.
Preferably, described housing comprises bonnet and forms the front panel of described accommodation space with described bonnet, and described antenna system is positioned on described bonnet and/or front panel.
Preferably, described housing adopts plastics, metal or glass to make.
Preferably, described antenna surface is also electroplate with corronil.
Preferably, described antenna is also coated with one deck priming paint.
Preferably, described antenna comprises one or more in main antenna, diversity antenna, gps antenna, WIFI antenna or NFC antenna.
Another technical scheme that the present invention solves the employing of its technical problem is: the manufacture method proposing a kind of antenna system as described above, and it comprises the following steps:
(1) on the surface of accommodation space, described laser activation coating is sprayed at described housing;
(2) laser activation coating described in laser activation;
(3) pattern of LDS technology shaping described antenna in described laser activation coating is adopted;
(4) described antenna pattern is electroplated;
(5) the surface spraying priming paint of described antenna pattern is being provided with.
Preferably, the material that in step (4), plating adopts is corronil.
Implement mobile terminal of the present invention and antenna system thereof, there is following beneficial effect: no matter which kind of material housing adopts, as long as LDS technology can be adopted at surface of shell contoured beam antenna in surface of shell spraying laser activation coating, do not have the restriction of material, the while that the RF performance of antenna obtaining maximized, mobile terminal can do thinner.
[accompanying drawing explanation]
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the structural representation of mobile terminal of the present invention;
Fig. 2 is the Making programme figure of antenna system in mobile terminal of the present invention.
[embodiment]
As shown in Figure 1, in a preferred embodiment of the invention, a kind of mobile terminal 100 comprise there is accommodation space housing, be located at main body 101 in accommodation space and circuit board.Housing comprises bonnet 102 and surrounds the front panel of accommodation space with bonnet 102.This mobile terminal 100 also comprises is located at the antenna system of bonnet 102 towards the surface of accommodation space.This antenna system comprises and is covered on bonnet 102 towards the laser activation coating on the surface of accommodation space and adopt LDS technology to take shape in antenna in laser activation coating.Understandable, front panel also may be used for contoured beam antenna towards the surface of accommodation space, as long as cover one deck laser activation coating on a surface.
Laser activation coating is a kind of special coating, and it can make LDS technology contoured beam antenna on any material.Therefore, use this can after laser activation coating, no matter bonnet 102 be that plastics, metal or glass or other materials can as the carriers of antenna system.In the present embodiment, bonnet 102 integrated injection molding.Understandable, antenna system can also take shape on other possible surfaces of mobile terminal 100.
In the present embodiment, antenna comprises main antenna 103, diversity antenna 104 and gps antenna 105.In other embodiments, antenna can also comprise NFC antenna and WIFI antenna.These antenna is all electrically connected with circuit board.
In addition, one deck corronil can also be electroplated in LDS antenna surface and cover one deck priming paint to protect antenna, ensureing the stable of its performance with the useful life of extension antenna.
Because antenna system is attached to the surface of bonnet 102, mobile terminal need not consider the problem of thickness when designing, therefore can do thin as much as possible, meet the development trend of mobile terminal slimming.And antenna system takes shape in the surface of bonnet 102, the RF performance of antenna system can be maximized.
Fig. 2 is the Making programme figure of antenna system in mobile terminal of the present invention.Its manufacture method mainly comprises following step:
(1) on the surface of accommodation space, laser activation coating is sprayed at bonnet 102;
(2) laser activation aforementioned laser washcoat;
(3) pattern of LDS technology contoured beam antenna in laser activation coating is adopted;
(4) pattern of plated antenna;
(5) the surface spraying priming paint of antenna pattern is being provided with.
Wherein, the material that in step (4), plating adopts is corronil.
Compared with the method for traditional LDS technology contoured beam antenna, this method does not have the restriction of material, can meet the development need of now mobile communication equipment well.And the requirement that the method does not have other special to production line and equipment (equipment continuing to use traditional LDS technology contoured beam antenna can be continued), therefore can not increase extra production cost.
