Abstract

A portable electronic apparatus with an embedded antenna module includes a main body, a flipper, and an axle having a hinge. The axle is used for connecting the main body and the flipper. The antenna module disposed in the axle is fixed to the main body. The antenna module is aligned to the hinge.

Claims

1. An embedded antenna device disposed in a portable electronic apparatus, the portable electronic apparatus at least comprising a hinge, the embedded antenna device comprising:

a sleeve having a cavity, the sleeve aligned with the hinge;

an antenna disposed in the cavity; and

a conductor electrically connecting the antenna and the portable electronic apparatus.

2. The embedded antenna device according to claim 1, -wherein the conductor comprises a cam disposed in the cavity for fixing the antenna inside the sleeve.

3. The embedded antenna device according to claim 2, wherein the conductor further comprises an elastic piece having a first end and a second end, the first end electrically connected with the cam, the second end protruding from the sleeve.

4. The embedded antenna device according to claim 3, wherein the portable electronic apparatus comprises a printed circuit board, the second end of the elastic piece closely connected to the printed circuit board.

5. The embedded antenna device according to claim 2, wherein the cam is a copper cam.

6. The embedded antenna device according to claim 1 further comprises a fixing portion having a non-circular flange for fixing the sleeve to the portable electronic apparatus.

7. The embedded antenna device according to claim 6, wherein the fixing portion further has a slit positioned on the non-circular flange for holding the first end of the elastic piece.

8. The embedded antenna device according to claim 1, wherein the antenna is a spiral antenna.

9. An embedded antenna device, comprising:

a sleeve having a first cavity;

a fixing portion having a second cavity, disposed adjacent to the sleeve;

an antenna received in the first cavity;

a cam having a first end and a second end, the first end of the cam inserted to the antenna, the second end of the cam received in the second cavity whereby the antenna is fixed in the sleeve; and

an elastic piece having a third end and a fourth end, the third end of the elastic piece electrically connected with the cam, the fourth end of the elastic piece protruding from the fixing portion, wherein the antenna is electrically conducted outside the sleeve by the elastic piece.

10. The embedded antenna device according to claim 9, wherein the fixing portion has a non-circular flange.

11. The embedded antenna device according to claim 10, wherein the fixing portion has a slit positioned on the non-circular flange for holding the first end of the elastic piece.

12. The embedded antenna device according to claim 9, wherein the cam is a copper cam.

13. The embedded antenna device according to claim 9, wherein the antenna is a spiral antenna.

14. A portable electronic apparatus, comprising:

a main body;

a flipper;

an axle comprising a hinge for connecting the main body and the flipper; and

an antenna module received in the axle and fixed to the main body, wherein the antenna module is aligned with the hinge.

15. The portable electronic apparatus according to claim 14, wherein the antenna module comprises:

a sleeve having a cavity;

an antenna disposed in the cavity; and

a conductor electrically connecting the antenna and the portable electronic apparatus.

16. The portable electronic apparatus according to claim 15, wherein the conductor further comprises a cam disposed in the cavity for fixing the antenna in the sleeve.

17. The portable electronic apparatus according to claim 15, wherein the conductor further comprises an elastic piece having a first end and a second end, the first end of the elastic piece electrically connected with the cam, while the second end of the elastic piece protrudes from the sleeve.

18. The portable electronic apparatus according to claim 14 further comprises a printed circuit board, the second end of the elastic piece closely connected with the printed circuit board.

19. The portable electronic apparatus according to claim 15, wherein the sleeve further comprises a non-circular flange, and the main body further comprises a groove, the non-circular flange fastened to the groove for fixing the antenna module to the main body.

20. The portable electronic apparatus according to claim 19, wherein the sleeve further comprises a slit positioned on the non-circular flange for receiving the elastic piece.
