Abstract

Mobile communication devices are provided. A mobile communication device includes a planar antenna, an input unit and a display unit pivotally connected to the input unit. The display unit includes a first casing having a first outer surface. The planar antenna includes a conductive element exposed on the first outer surface.

Claims

1. A mobile communication device, comprising:

an input unit;

a display unit pivotally connected to the input unit, wherein the display unit comprises a first casing, and the first casing has an outer surface; and

a planar antenna, comprising a conductive element exposed on the outer surface.

2. The mobile communication device as claimed in claim 1, further comprising a pattern exposed on the outer surface, wherein the conductive element constitutes at least a part of the pattern.

3. The mobile communication device as claimed in claim 1, further comprising a hinge pivotally connecting the input unit and the display unit.

4. The mobile communication device as claimed in claim 1, wherein the planar antenna further comprises a ground connected to the first casing.

5. The mobile communication device as claimed in claim 4, wherein the first casing further comprises a first inner surface, and the ground is a metal or a conductive coating on the first inner surface.

6. The mobile communication device as claimed in claim 1, wherein the planar antenna is a patch antenna.

7. The mobile communication device as claimed in claim 1, wherein the planar antenna is a slot type antenna.

8. The mobile communication device as claimed in claim 1, wherein the display unit further comprises a printed circuit board, and the planar antenna further comprises a ground disposed on the printed circuit board.

9. The mobile communication device as claimed in claim 8, wherein the ground is metal.

10. The mobile communication device as claimed in claim 8, wherein the display unit further comprises a main display, and the printed circuit board comprises a display drive circuit to drive and control the main display.

11. The mobile communication device as claimed in claim 8, wherein the display unit further comprises a sub display disposed on the first casing, and the printed circuit board comprises a display drive circuit to drive and control the sub display.

12. The mobile communication device as claimed in claim 1, wherein the display unit further comprises a second casing connected to the first casing, and the planar antenna further comprises a ground connected to the second casing, separated from the conductive element.

13. The mobile communication device as claimed in claim 12, wherein the second casing comprises a second inner surface substantially parallel to the first outer surface, and the ground is a metal or a conductive coating on the second inner surface.

14. The mobile communication device as claimed in claim 1, wherein the planar antenna is a planar inverted F antenna (PIFA).

15. The mobile communication device as claimed in claim 1, wherein the planar antenna further comprises a ground exposed on the first outer surface.
