Abstract

An electronic device having antenna structure is provided. The electronic device includes a first body, a pivot assembly, a second body and an antenna structure. The pivot assembly is pivoted to the first body along a first axis. The second body is pivoted to the pivot assembly along a second axis. The antenna structure is disposed in the pivot assembly and has a first radiation portion, a second radiation portion and a third radiation portion. The first radiation portion and the second radiation portion have a slot therebetween to form a slot antenna. The third radiation portion forms a monopole antenna and is aligned to the slot. The third radiation portion and the slot are not coplanar.

Claims

1. An electronic device, comprising:

a first body;

a pivot assembly, pivoted to the first body along a first axis;

a second body, pivoted to the pivot assembly along a second axis;

at least one antenna structure, disposed in the pivot assembly and having a first radiation portion, a second radiation portion and a third radiation portion, wherein the first radiation portion and the second radiation portion have a slot therebetween to form a slot antenna, the third radiation portion forms a monopole antenna and is aligned to the slot, and the third radiation portion and the slot are not coplanar.

2. The electronic device as recited in claim 1, wherein the second body is opened from or closed to the first body through a relative pivoting between the first body and the pivot assembly along the first axis.

3. The electronic device as recited in claim 1, wherein the first axis is perpendicular to the second axis.

4. The electronic device as recited in claim 1, wherein the pivot assembly has a metal shaft, the antenna structure has a grounding portion, and the grounding portion is connected to the metal shaft.

5. The electronic device as recited in claim 1, wherein a length of the slot is equal to one-fourth or one-half of a wavelength of a first signal, a length of the third radiation portion equals to one-fourth of a wavelength of a second signal.

6. The electronic device as recited in claim 5, wherein a frequency of the second signal is greater than a frequency of the first signal.

7. The electronic device as recited in claim 1, wherein the antenna structure has a connecting section, the connecting section is connected with the first radiation portion and located in the slot, the third radiation portion comprises a first section and a second section that are bent with each other, and the first section is connected between the connecting section and the second section.

8. The electronic device as recited in claim 1, further comprising a cable, wherein the cable comprises a signal line and a ground line, the connecting section has a feed point, the second radiation portion has a ground point, the signal line is connected to the feed point, and the ground line is connected to the ground point.

9. The electronic device as recited in claim 1, wherein the pivot assembly has a plastic casing, and the antenna structure is disposed on the plastic casing.

10. The electronic device as recited in claim 1, wherein the pivot assembly has a metal casing, and the antenna structure is disposed on the metal casing.

11. The electronic device as recited in claim 10, wherein the pivot assembly has a plastic member, and the plastic member is engaged in the metal casing and aligned to the slot.

12. The electronic device as recited in claim 1, wherein the second radiation portion has a folded wall.

13. The electronic device as recited in claim 1, wherein the slot has an open end, the antenna structure has a feed point in the slot, and a width of the slot gradually increases from the feed point towards the open end.

14. The electronic device as recited in claim 1, wherein the slot is a closed slot.
