Abstract

A housing for a wireless communication device includes a decorative film having an antenna pattern formed thereon, a protective coating covering the antenna pattern, and a substrate moldingly attached to the decorative film and the protective coating. The antenna pattern is a conductive ink coating. The antenna pattern and the protective coating are sandwiched between the decorative film and the substrate.

Claims

1. A wireless communication device, comprising:

a main body comprising a printed circuit board therein, the printed circuit board comprising a conductive pole mounted thereon, for sending and/or receiving electromagnetic waves; and

a housing mounted on the main body, comprising;

a plastic decorative film having an antenna pattern directly formed thereon;

a protective coating covering the antenna pattern; and

a substrate moldingly attached to the decorative film and the protective coating;

wherein the antenna pattern is a conductive ink coating, the antenna pattern and the protective coating being sandwiched between the decorative film and the substrate, a gap between the conductive pole and the antenna pattern is less than 0.5 mm.

2. The wireless communication device as claimed in claim 1, wherein the substrate is made of a moldable material selected from the group consisting of polycarbonate, acrylonitrile butadiene styrene, polyethylene, poly ethylene terephthalate, and poly propylene, poly methyl methacrylate, and silicone.

3. The wireless communication device as claimed in claim 1, wherein the conductive pole of the printed circuit board enters into a through hole of the substrate and is in contact with the antenna pattern.

4. The wireless communication device as claimed in claim 1, wherein the conductive ink coating has at least one of gold powder, silver powder, copper powder, carbon powder, and graphite powder mixed therein.

5. The wireless communication device as claimed in claim 1, wherein the antenna pattern is from 0.002 mm to 0.015 mm thick.

6. The wireless communication device as claimed in claim 1, wherein the protective coating is an ink coating from 0.002 mm to 0.015 mm thick.
