Abstract

A method of manufacturing an antenna-embedded case for a mobile communications terminal includes providing an antenna pattern, forming a first injection-molded member covering one surface of the antenna pattern, and disposing the first injection-molded member, provided with the antenna pattern on one surface thereof, in a second mold with the antenna pattern disposed in a space inside the second mold, and injection-molding a second injection-molded member covering the other surface of the antenna pattern to embed the antenna pattern between the first injection-molded member and the second injection-molded member.

Claims

1. A method of manufacturing an antenna-embedded case for a mobile communications terminal, the method comprising:

providing an antenna pattern;

forming a first injection-molded member covering one surface of the antenna pattern; and

disposing the first injection-molded member, provided with the antenna pattern on one surface thereof, in a second mold with the antenna pattern disposed in a space inside the second mold, and injection-molding a second injection-molded member covering the other surface of the antenna pattern to embed the antenna pattern between the first injection-molded member and the second injection-molded member.

2. The method of claim 1, wherein the antenna pattern is formed into a flat type, and includes an interconnection pin extending from one surface of the antenna pattern.

3. The method of claim 2, wherein in the forming of the first injection-molded member, injection-molding is performed such that an open end of the interconnection pin is exposed to an opposite surface to a surface of the first injection-molded member contacting the antenna pattern.

4. The method of claim 1, further comprising processing the antenna pattern into a structure having a three-dimensional shape, before the forming of the first injection-molded member.

5. The method of claim 1, wherein the forming of the first injection-molded member comprises:

inserting the antenna pattern in a first mold having a an internal space having a shape of the first injection-molded member; and

injecting a molding material into the first mold and molding the first injection-molded member covering one surface of the antenna pattern.

6. A mobile communications terminal manufactured according to the method of manufacturing an antenna-embedded case for a mobile communications terminal of claim 1.

7. An antenna-embedded case for a mobile communications terminal, comprising:

an antenna pattern;

a first injection-molded member covering one surface of the antenna pattern; and

a second injection-molded member injection-molded to cover the other surface of the antenna pattern such that the antenna pattern is embedded between the first injection-molded member and the second injection-molded member.

8. The antenna-embedded case of claim 7, wherein the antenna pattern is formed into a flat type, and includes an interconnection pin extending from one surface of the antenna pattern and having one end exposed to a surface of the first injection-molded member.

9. The antenna-embedded case of claim 7, wherein the first injection-molded member and the second injection-molded member are formed of different materials.

10. The antenna-embedded case of claim 9, wherein the first injection-molded member includes a material for shielding electromagnetic waves.
