Abstract

A spray non-contact cutting type antenna fabrication method is disclosed to have an antenna radiator be formed on a plastic shell by means of spray-painting a metallic spray paint on the surface of the plastic shell and then cutting the metallic coating into shape, and then to cover the plastic shell with a cover layer by means of an insert molding or spray paining technique to have the antenna radiator be enveloped in the cover layer.

Claims

1. A spray non-contact cutting type antenna fabrication method, comprising the steps of:

a) forming a plastic shell;

b) spray-painting said plastic shell with a metallic spray paint to form a metal coating layer on said plastic shell;

c) cutting said metal coating layer into an antenna subject to a predetermined pattern; and

d) covering said plastic shell with a cover layer by means of an insert molding technique to have said antenna be enveloped in said cover layer.

2. The spray non-contact cutting type antenna fabrication method as claimed in claim 1, wherein said plastic shell has a feed-in contact hole and a grounding contact hole;

the step b) of spray-painting said plastic shell with a metallic spray paint to form a metal coating layer on said plastic shell is to have said metallic spray paint be coated in said feed-in contact hole and said grounding contact hole to form therein a feed-in contact and a grounding contact.

3. A spray non-contact cutting type antenna fabrication method, comprising the steps of:

a) forming a plastic shell;

b) spray-painting said plastic shell with a metallic spray paint to form a metal coating layer on said plastic shell;

c) cutting said metal coating layer into an antenna subject to a predetermined pattern; and

d) covering said plastic shell with a cover layer by means of a spray painting technique to have said antenna be enveloped in said cover layer.

4. A device shell comprising:

a plastic shell;

an antenna formed of a metallic spray paint been spray-painted on said plastic shell and cut into shape subject to a predetermined pattern; and

a cover layer covered on said plastic shell over said antenna by means of an insert molding technique.

5. The device shell as claimed in claim 4, wherein said plastic shell comprises a feed-in contact hole and a grounding contact hole;

said antenna comprises a feed-in contact and a grounding contact respectively extended to the inside of said feed-in contact hole and said grounding contact hole.
