As a kind of preferred version, described first line and the second circuit are respectively positioned at a left side for the lower end of mobile phone shell moulding Right both sides corner, the 5th circuit and the 4th circuit are located at the left and right sides corner of the upper end of mobile phone shell moulding respectively, and this Three circuits are located at by the downside of the 5th circuit.

As a kind of preferred version, described first line is MAIN_LOW antenna end, and this second circuit is MAIN_HI antenna End, this tertiary circuit is WIFI antenna end, and the 4th circuit is SUB antenna end, and the 5th circuit is gps antenna end.

As a kind of preferred version, fill metal in described via and form conducting body.

As a kind of preferred version, the top surface of described conducting body is concordant with the highest face of circuit.

The utility model compared with prior art has clear advantage and beneficial effect, specifically, by above-mentioned technology Scheme understands：

Form each line slot by laser carving is carried out to mobile phone shell moulding, and coordinate to the plating of each carrying out of line slot Metal and form each circuit, thus constituting antenna for mobile phone, instead of the mode of printing of tradition, each circuit of this product is thick Thin uniformly serviceability is good, and once change plating can complete, and make efficiency is high.

For more clearly illustrating architectural feature of the present utility model and effect, it is right to come with specific embodiment below in conjunction with the accompanying drawings The utility model is described in detail.

Specific embodiment

Refer to shown in Fig. 1 to Fig. 8, that show the concrete structure of the preferred embodiment of the utility model, include Mobile phone shell moulding 10.

The back side laser carving of this mobile phone shell moulding 10 is formed with first line groove 11, the second line slot 12, tertiary circuit groove 13rd, the 4th line slot 14 and the 5th line slot 15, this first line groove 11, the second line slot 12, tertiary circuit groove 13, the 4th line Homogenizing gold-plated genus in road groove 14 and the 5th line slot 15 and be respectively formed with first line 21, the second circuit 22, tertiary circuit 23, 4th circuit 24 and the 5th circuit 25, this first line 21, the second circuit 22, tertiary circuit 23, the 4th circuit 24 and the 5th line The front that corresponding via 30 connects mobile phone moulding 10 is respectively passed through on road 25.

In the present embodiment, described first line 21 and the second circuit 22 are respectively positioned at the lower end of mobile phone shell moulding 10 Left and right sides corner, the 5th circuit 25 and the 4th circuit 24 are located at the left and right sides of the upper end of mobile phone shell moulding 10 respectively Angle, this tertiary circuit 23 is located at by the downside of the 5th circuit 25.And, described first line 21 is MAIN_LOW antenna end, should Second circuit 22 is MAIN_HI antenna end, and this tertiary circuit 23 is WIFI antenna end, and the 4th circuit 24 is SUB antenna end, should 5th circuit 25 is gps antenna end.
