Embodiment 1

[0031] This embodiment illustrates the antenna of the present invention and its manufacturing method.

[0032] Using Ultramid plastic produced by BASF Company (the plastic base material is aromatic polyamide) as raw material, an injection molding machine (TOYO Company, Model 100T) is used to prepare a mobile phone antenna bracket, which contains an organic metal compound The thickness of the layer of plastic is 1.3 mm.

[0033] Use a laser machine (Tide laser machine, model DPY-M50) to irradiate the surface of the bracket with laser light to form a groove (the shape of the groove is as follows figure 1 Shown in the shaded part of ), the depth of the groove is 0.05 mm.

[0034] Wash the stent after laser irradiation with water. Then take the support as the cathode, and copper as the anode, electroplating in the electroplating solution, the composition of the electroplating solution and the content of each component are: copper sulfate of 1.8 grams per liter, sodium hydroxide ...

Embodiment 2

[0036] This embodiment illustrates the antenna of the present invention and its manufacturing method.

[0037] ABS / PC plastics (acrylonitrile-butadiene-styrene copolymer / polycarbonate) produced by Pocan plastics produced by Bayer Corporation (the plastic base material is polybutylene terephthalate) and GE Corporation As raw material, prepare the support of mobile phone antenna by two-color injection molding machine (Farrack (FUNAC) company, two-color machine model 100T), the described support that obtains comprises the plastics that contains organometallic compound and does not contain organometallic compound Plastic, the thickness of the plastic containing the organic metal compound is 0.5 mm, and the thickness of the plastic not containing the organic metal compound is 0.8 mm.

[0038] Use a laser machine (Tide laser machine, model DPY-M50) to carry out laser irradiation on the surface of the plastic layer containing the organometallic compound of the bracket, and form groov...

Embodiment 3

[0041] This embodiment illustrates the antenna of the present invention and its manufacturing method.

[0042] The Bayblend plastic (the plastic base material is ABS / PC) that Bayer / Albis company produces and the ABS / PC plastic (acrylonitrile-butadiene-styrene copolymer / polycarbonate) that GE company manufacturer produces are raw material, Prepare the support of mobile phone antenna by two-color injection molding machine (Faraq (FUNAC) company, two-color machine model 100T), the described support that obtains comprises the plastics that contains organometallic compound and does not contain the plastics of organometallic compound, so The thickness of the plastic containing the organometallic compound is 0.5 mm, and the thickness of the plastic not containing the organometallic compound is 0.8 mm.

[0043] Use a laser machine (Tide laser machine, model DPY-M50) to carry out laser irradiation on the surface of the plastic layer containing the organometallic compound of the bracket...
