Case of electronic device having antenna pattern frame embedded therein, mold therefor and method of manufacturing thereof
There is provided a case of an electronic device having an antenna pattern embedded therein, the case including: a radiator frame injection molded so that a radiator including an antenna pattern part and formed on a film is formed on one surface thereof; a case frame injection molded upwardly of the radiator frame and provided with the radiator embedded between the radiator frame and the case frame; and a boundary part forming a boundary between the radiator frame and the case frame and having a groove formed inwardly of the case frame.
1. A case of an electronic device having an antenna pattern embedded therein, the case comprising:
a radiator frame having a through hole, a radiator including an antenna pattern part disposed on a surface of the radiator frame, the antenna pattern part being apart from the through hole with a predetermined distance; and
a case frame covering the radiator frame such that the case frame is secured to the radiator frame via the through hole.
2. The case of claim 1 , wherein the antenna pattern part includes a loop antenna wound around an outer portion of the through hole.
3. The case of claim 1 , wherein the radiator frame and the case frame are integrally formed.
4. The case of claim 2 , further comprising a through hole boundary groove formed at a boundary between the case frame and the through hole.
5. The case of claim 4 , wherein the through hole boundary groove has an inclination, a depth of which becomes shallower in a direction from the through hole toward the case frame formed at an inner portion of the through hole.
6. The case of claim 1 , further comprising an outer boundary groove formed at a boundary between an outer portion of the radiator frame and the radiator frame.
7. The case of claim 6 , wherein the outer boundary groove has an inclination, a depth of which becomes shallower in a direction from the radiator frame toward the case frame formed at an outer portion of the radiator frame.
8. The case of claim 1 , wherein the antenna pattern part includes an antenna coil wound multiple times so that a low frequency signal may be transmitted or received.
9. The case of claim 8 , wherein the radiator frame includes an over-mold part covering a portion of each of adjacent antenna pattern parts.
10. The case of claim 8 , wherein the radiator frame includes an over-mold part covering all antenna pattern parts adjacent thereto.
11. The case of claim 1 , wherein the radiator includes a connection terminal part formed on one surface of the radiator frame, and the connection terminal part is injection molded to be exposed on a connection terminal support formed to protrude to an outer portion of the radiator frame.
12. The case of claim 9 , wherein the connection terminal support includes an interconnection hole formed in a position corresponding to that of the connection terminal part.
13. The case of claim 1 , wherein the radiator frame includes an outer jaw disposed to be higher than an upper surface of the radiator.
14. The case of claim 1 , wherein the radiator includes at least two differently patterned antenna pattern parts.
15. The case of claim 1 , wherein the film is made of a polymer plastic material containing a Cu component.
16. The case of claim 1 , wherein the case frame is engaged with the radiator frame via the through hole via molding.
17. A case of an electronic device having an antenna pattern embedded therein, the case comprising:
a radiator frame injection molded so that a radiator including an antenna pattern part and formed on a film is formed on one surface thereof;
a case frame injection molded upwardly of the radiator frame and provided with the radiator embedded between the radiator frame and the case frame; and
a boundary part forming a boundary between the radiator frame and the case frame and having a groove formed inwardly of the case frame,
wherein the radiator frame includes a through hole, and the through hole is inserted into an inner boundary jaw of a mold of the case of an electronic device through which the case frame is injection molded.
18. The case of claim 17 , further comprising a through hole boundary groove formed at a boundary between the case frame and the through hole.
19. The case of claim 17 , further comprising an outer boundary groove formed at a boundary between an outer portion of the radiator frame and the radiator frame.
20. A case of an electronic device having an antenna pattern embedded therein, the case comprising:
a radiator frame having a through hole, a radiator including an antenna pattern part disposed on a surface of the radiator frame, the antenna pattern part being apart from the through hole with a predetermined distance; and
a case frame covering the radiator frame and having a mold portion being inserted to the through hole so that the case frame is secured to the radiator frame.
21. A case of an electronic device, the case comprising:
a radiator frame comprising a through hole;
an antenna pattern disposed on the radiator frame so that the antenna pattern surrounds the through hole; and
a case frame attached to the radiator frame so that the antenna pattern is disposed between the radiator frame and the case frame;
wherein the case frame comprises a projection extending into the through hole; and
the projection comprises a boundary groove adjoining an edge of the through hole.
