Embodiment

Below form with regard to the structure of the utility model, and the effect and the advantage that can produce, conjunction with figs., the preferred embodiment detailed description of act the utility model is as follows.Must understand, description is only applicable to an embodiment of the utility model, is not the scope in order to restriction the utility model.

The embodiment of the utility model is following, and please refer to shown in Fig. 2-3, and the machine shell panel of the utility model comprises:

First planar dielectric (being generally a glassy layer) 10 is desired to hold the antenna metal and is sentenced the mode of the face of falling and form one and fall face district 20 at the edge of this first planar dielectric; Wherein fall the face district and be about the thickness of the radiating antenna of desiring to hold than remaining surperficial recessed degree of depth.Wherein this first planar dielectric 10 can be the panel of the display screen top of an electronic installation, and its material can be glass, plastic cement, polyester film or other transparent material, and generally this first planar dielectric also can form the base material of Touch Screen.Forming first planar dielectric in the utility model falls the method for face and can be modes such as laser carved, etching, sandblast, grinding, cutting.

Second planar dielectric 30 (being generally a plastic layer or polyester film) is positioned at the top of this first planar dielectric 10, decorates China ink layer 40 in edge's coating one of this second planar dielectric 30.

At least one antenna metal level 50 (being radiating antenna) can be produced on the below of the decoration China ink layer 40 of this second planar dielectric 30; Or be produced in the face that the falls district 20 of first planar dielectric 10.The production method of antenna metal level 50 can adopt printing in the utility model, sputter, and electrochemical deposition (for example, electroplating), vapor deposition, other physical gas phase deposition technologies, chemical vapour deposition technique, japanning is sprayed paint, or these technological combinations, or the like.Also can adopt FPC (Flexible print circuit) flexible printed circuit to make.When adopting the FPC flexible printed circuit to make antenna, antenna can fit in the face that the falls district 20 of first planar dielectric 10, or fits in the below of decorating China ink layer 40, and the position in the face that the falls district 20 of corresponding first planar dielectric 10 in position.The degree of depth in the face that the falls district 20 of first planar dielectric 10 then cooperates the gross thickness of FPC antenna itself and employed applying glue.

Wherein this second planar dielectric 30 (together with the decoration China ink layer 40 and the antenna metal level 50 that apply on it) is layed onto on this first planar dielectric 10 so that the mode of fitting is glutinous, between this second planar dielectric 30 and this first planar dielectric 10, forms an optical clear glue-line 60.This antenna metal level 50 will push this optical lens gelatin 60 and moves toward the face that the falls district 20 of these first planar dielectric 10 in the applying process.Fall in the face district 20 when antenna metal level 50 is made in, antenna metal level 50 can directly be filled and led up the cup depth that falls face district 20, with optical lens gelatin 60 first planar dielectric 10 is fitted in second planar dielectric 30 more afterwards.

Please refer to Fig. 2-3, it shows the side sectional view and the vertical view of the utility model.

When on second planar dielectric 30, making one deck antenna metal level 50; The banded position 31 that one protrusion is arranged at an end of this second planar dielectric 30; The current fed line 51 of this antenna metal level 50 and earth connection 52 can be produced on this banded position 31, and along with banded position 31 extends out.Afterwards with FPC (flexible printed circuit) 70 and current fed line 51 and earth connection 52 crimping; And when follow-up assembling, banded position 31 being bent and is hidden in interior downwards, the vestige that so can avoid on second planar dielectric 30, being produced after the circuit crimping exposes to the visible range of this second planar dielectric 30.

After above way can avoid first planar dielectric 10 and second planar dielectric 30 to fit, antenna metal level 50 protruded from second planar dielectric 30.Therefore on this second planar dielectric 30, can see smooth outward appearance, can not influence whole outward appearance because of this antenna metal level 50 is set.

The advantage of the utility model is fallen the face place for the formation face of falling on first planar dielectric 10 of a panel makes antenna can be housed in this, and makes the surface of whole electronic installation not have the vestige of antenna protrusion, presents beautiful smooth outward appearance; The current fed line of this antenna metal level and earth connection can be produced on this banded position; And along with banded position extends out; And with after flexible printed circuit is connected; The banded position bending of current fed line and earth connection also is hidden in interior, can avoid circuit crimping vestige to expose to the visible range on this casing surface.

Above-listed detailed description is specifying to a possible embodiments of the utility model; Only this embodiment is not the claim in order to restriction the utility model; Allly do not break away from the equivalence that the utility model skill spirit does and implement or change, all should be contained in the claim of the utility model.
