Abstract

A mobile phone includes an antenna of relatively small thickness, and a shelter member of non-metal material mounted in such a manner to conceal the antenna underneath. A logo is provided on an outer face of the shelter member to provide an aesthetic appearance of the mobile phone.

Claims

1. An electronic instrument comprising:

an outer metal casing;

a mother board disposed within said outer metal casing;

a coupling wire;

an antenna disposed on said outer metal casing and electrically connected to said mother board by said coupling wire; and

a shelter member disposed on said outer metal casing in such a manner to conceal said antenna thereunder.

2. The electronic instrument according to claim 1, wherein said shelter member is made from non-metal materials, which include plastic or paper.

3. The electronic instrument according to claim 1, wherein said shelter member is provided with a logo or a label.

4. The electronic instrument according to claim 1, wherein said antenna has a plate configuration, and includes a printed circuit board.

5. The electronic instrument according to claim 1, wherein said antenna has a plate configuration, and is a patch antenna.

6. The electronic instrument according to claim 1, wherein said antenna has a plate configuration, and includes a FPC (flexible printed circuit) or a ceramic antenna.

7. The electronic instrument according to claim 1, wherein said outer metal casing has an outer surface, and a recess that extends inwardly from said outer surface, said antenna being disposed in said recess.

8. The electronic instrument according to claim 7, wherein said recess in said outer metal casing is defined by a recess-confining wall that has a bottom wall portion formed with a through hole, said coupling wire extending through said through hole in said bottom wall portion and electrically interconnecting said mother board and said antenna.

9. The electronic instrument according to claim 8, wherein said bottom wall portion of said recess has a depth ranging from 2 mm to 4 mm measured with respect to the outer surface of said outer metal casing.

10. An electronic instrument comprising:

a casing enclosing a plurality of electronic parts of said instrument, and having an outer surface and a recess that extends inwardly from said outer surface, said recess being defined by a recess-confining wall that has a bottom wall portion formed with a through hole;

a mother board disposed within said casing below said recess;

an antenna disposed within said recess in said casing;

a co-axial coupling wire extending through said through hole in said recess for interconnecting said mother board and said antenna; and

a shelter member disposed on said casing in such a manner to cover said recess and said antenna thereunder.

11. The electronic instrument according to claim 10, wherein said casing is made from a metal material.

12. The electronic instrument according to claim 10, wherein said casing is formed with an electroplating layer on said outer surface thereof.

13. The electronic instrument according to claim 10, wherein said shelter member is made from non-metal materials, which include plastic or paper.

14. The electronic instrument according to claim 10, wherein said antenna has a plate configuration, and includes a printed circuit board.

15. The electronic instrument according to claim 10, wherein said antenna has a plate configuration, and is a patch antenna.

16. The electronic instrument according to claim 10, wherein said antenna has a plate configuration, and includes a FPC (flexible printed circuit) or a ceramic antenna.

17. The electronic instrument according to claim 10, wherein said bottom wall portion of said recess in said casing has a depth ranging from 2 mm to 4 mm measured with respect to said outer surface of said casing.

18. An electronic instrument comprising:

a metal casing formed with a recess defining an opening for access to said recess;

an antenna disposed in said recess for transmitting and receiving signals via said opening; and

a shelter member disposed on said casing in such a manner to cover said opening of said recess.

19. The electronic instrument according to claim 18, wherein said shelter member is provided with a logo on an outer face thereof.

20. The electronic instrument according to claim 18, wherein said shelter member is made from a non-conductive material.

21. The electronic instrument according to claim 18, wherein said antenna has a plate configuration, and includes a printed circuit board, a patch antenna, a FPC (flexible printed circuit) or a ceramic antenna.
