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 a three-dimensional metallic antenna pattern including first and second surfaces and an interconnection pin extending from the first surface;

forming a first injection-molded member including first and second surfaces and covering the first surface of the antenna pattern from which the interconnection pin extends; and

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

the interconnection pin and the antenna pattern are formed in an integrated manner.

2. The method of claim 1, wherein the antenna pattern excluding the interconnection pin is formed into a flat type.

3. The method of claim 2, wherein the forming comprises injection-molding the first injection-molded member such that an open end of the interconnection pin is exposed to the second surface of the first injection-molded member.

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

5. The method of claim 1, wherein the forming comprises:

inserting the antenna pattern in a first mold including a 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 the first surface of the antenna pattern.

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

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

a three-dimensional metallic antenna pattern including first and second surfaces and an interconnection pin extending from the first surface;

a first injection-molded member including first and second surfaces and covering the first surface of the antenna pattern from which the interconnection pin extends; and

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

the interconnection pin and the antenna pattern are formed in an integrated manner.

8. The antenna-embedded case of claim 7, wherein the antenna pattern excluding the interconnection pin is formed into a flat type.

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.
