Abstract
The utility model discloses a small-sized radio-frequency antenna molded through three-dimensional printing. The small-sized radio-frequency antenna comprises an antenna bearing base material and an antenna pattern arranged on the base material, wherein the surface of the base material on which the antenna pattern is arranged is a three-dimensional face, and the antenna pattern is formed by bonding an electric-conducting printing ink coating with the surface of the base material into a whole by using a three-dimensional printing process. According to the utility model, an existing plastic member in mobile equipment can be utilized to serve as a radio-frequency antenna bearing base material, the three-dimensional printing process is directly adopted to print the antenna pattern onto the surface of the base material to form the radio-frequency antenna without additional design and arrangement of the base material, and the small-sized radio-frequency antenna is small in occupied space and easy to manufacture and has a favorable electric performance.
Description
Technical field
The utility model relates to a kind of radio-frequency antenna architecture advances technology.
Background technology
Mobile communication terminal device such as mobile phone, notebook etc. all need radio-frequency antenna to carry out the emission and the reception of electromagnetic wave signal, and along with the volume at terminal constantly dwindles, improving constantly of cost pressure had higher requirement to design, the making of radio-frequency antenna.What radio-frequency antenna required good radiance, bigizationner utilizes spatial volume, lower production and material cost.
Radio-frequency antenna can be divided into according to its manufacture method at present:
1. shell fragment hot melten type radio-frequency antenna, such antenna holder is a plastic material, utilizes injection mo(u)lding; The metal radiation fin is a sheet metal, through stamping-out, bending technological forming.The two separate machined uses the hot melt post to carry out fixed to one another at last.This frame mode can produce the rigging error between antenna holder and the metal clips on the one hand, also be difficult to accomplish " driving fit " fully on the other hand between the two, thereby cause consistency bad, even serious meeting influences the complete machine performance of mobile phone.
2. FPC (FPC) form radio-frequency antenna, such antenna be with the antenna radiation unit design on FPC, use gum the FPC antenna to be pasted the mobile phone location of appointment at last.Owing to its have non-corrosive, long service life, and the low advantage of cost enjoy the favor of mobile phone producer.But the existing problem of such antenna is to debug inadequately to make things convenient for.
3. double-shot moulding formula radio-frequency antenna, such antenna holder adopts two kinds of material different injection mo(u)ldings, a kind ofly is the PC material, another kind ofly is the ABS material, and wherein the PC material is support, and ABS expects formation antenna radiation unit Wiring structure.After the injection mo(u)lding, the re-plating nickel dam.Because the PC material can not nickel plating in the electroplating process, and the ABS material can plated with nickel, therefore after plating, has only the surface of ABS to keep metallic nickel.Metallic nickel is the radiant body of antenna, and PC is a support, and ABS is a transition bracket, thereby accomplishes the whole machining process process of antenna.
The utility model content
In view of this, the utility model technical problem that will solve provides a kind of three dimensional printing moulding Miniature RF antenna little, that be easy to make that takes up room.
The utility model adopts following scheme to realize:
A kind of three dimensional printing moulding Miniature RF antenna; Comprise the antenna supporting substrate and be arranged at the antenna pattern on the base material; The substrate surface that antenna pattern is set is the 3 D stereo face, and said antenna pattern is the electrically conductive ink coating, fitting through three-dimensional printing art and substrate surface is one.
As improvement, at the antenna pattern electroplating surface or be coated with to be equipped with and prevent antenna pattern oxidation and the protective layer that increases resistance to wear to such scheme.
Existing plastic parts double as is the congenital supporting substrate of radio frequency in the utility model mobile device capable of using; Directly adopt three-dimensional printing art that the nature graphic printing is formed radio-frequency antenna in this substrate surface; And need not to design in addition and install additional base material; It is little to take up room, and is easy to make, and has good electric property.
Description of drawings
Fig. 1 is the utility model embodiment overall structure sketch map.
Embodiment
Below will combine accompanying drawing and embodiment that the utility model is described in further detail for the ease of it will be appreciated by those skilled in the art that:
Shown in accompanying drawing 1, the radio-frequency antenna that the utility model embodiment discloses adopts three-dimensional printing art to make, and volume is little, is easy to make, and can in mobile terminal device, has straight forming on the plastic parts now, is installed on use and does not receive spatial constraints.
The three dimensional printing moulding Miniature RF antenna that is designed in this programme comprises antenna supporting substrate 1 and is arranged at the antenna pattern 2 on the base material 1; Wherein, Base material 1 surface that antenna pattern 2 is set is the 3 D stereo face; Present embodiment is a three-dimension curved surface, and antenna pattern 2 is an electrically conductive ink coating and to fit through three-dimensional printing art and base material 1 this three-dimension curved surface surface be one.
In order to protect the antenna pattern 2 on base material 1 surface, at antenna pattern 2 electroplating surfaces or be coated with to be equipped with and prevent antenna pattern 2 oxidations and the protective layer that increases resistance to wear.
Such radio-frequency antenna can be through various feed syndeton modes, are connected to such as metal clips mode or Pogo pin mode etc. on the small-sized mobile communication terminal device circuit such as mobile phone, realize antenna function.
More than be a wherein concrete implementation of the utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these conspicuous replacement forms all belong to the protection range of the utility model.
Claims (2)
1. three dimensional printing moulding Miniature RF antenna; Comprise antenna supporting substrate (1) and be arranged at the antenna pattern (2) on the base material; It is characterized in that: the substrate surface that antenna pattern is set is the 3 D stereo face, and said antenna pattern is the electrically conductive ink coating, fitting through three-dimensional printing art and substrate surface is one.
2. three dimensional printing moulding Miniature RF antenna according to claim 1 is characterized in that: at the antenna pattern electroplating surface or be coated with to be equipped with and prevent antenna pattern oxidation and the protective layer (3) that increases resistance to wear.
