Abstract

A housing for a wireless communication device includes a substrate and an antenna pattern formed on the substrate. The antenna pattern is a conductive paint coating.

Claims

1. A housing for a wireless communication device, comprising:

a substrate; and

an antenna pattern disposed on the substrate;

wherein the antenna pattern is a conductive paint coating.

2. The housing as claimed in claim 1, wherein the substrate is acrylonitrile-butadiene-styrene, polycarbonate, or a mixture of acrylonitrile-butadiene-styrene and polycarbonate.

3. The housing as claimed in claim 1, wherein the substrate is silicone or glass.

4. The housing as claimed in claim 1, wherein the conductive paint coating comprises a resin component and at least one conductive component consisting of gold powder, silver powder, copper powder, carbon powder, and graphite powder.

5. A wireless communication device, comprising:

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

a housing mounted on the main body, comprising;

a substrate; and

an antenna pattern disposed on the substrate;

wherein the antenna pattern is a conductive paint coating.

6. The wireless communication device as claimed in claim 5, wherein the substrate is acrylonitrile-butadiene-styrene, polycarbonate, or a mixture of acrylonitrile-butadiene-styrene and polycarbonate.

7. The wireless communication device as claimed in claim 5, wherein the substrate is silicone or glass.

8. The wireless communication device as claimed in claim 5, wherein the gap between the conductive pole and the antenna pattern is less than 0.5 mm.

9. The wireless communication device as claimed in claim 5, wherein the conductive pole contacts the antenna pattern.

10. A method for manufacturing a housing for a wireless communication, comprising:

providing a substrate; and

spray coating a conductive paint onto the substrate to form an antenna pattern.

11. The method as claimed in claim 10, wherein the substrate is made of acrylonitrile-butadiene-styrene, polycarbonate, or a mixture of acrylonitrile-butadiene-styrene and polycarbonate.

12. The method as claimed in claim 10, further comprising a step of plasma activating one surface of the substrate in a plasma of nitrogen gas, oxygen gas, or hydrogen gas, the antenna pattern being formed on the plasma activated surface of the substrate.

13. The housing as claimed in claim 10, wherein the substrate is silicone or glass.
