Abstract

The invention relates to a wireless communication device 1 having an upper part 10 and a bottom part 11, the upper part 10 comprising one or more transmission antenna device(s) 12a, 12b; 15. The upper part 10 and the bottom part 11 are arranged movably in relation to each other, so that the bottom part 11, in use mode, is closer to the user than the upper part 10. The bottom part 11 comprises one or more reception antenna device(s) 14a, 14b, 14c, 14d.

First claim

The invention claimed is:

1. A wireless communication device having an upper part and a bottom part, the upper part comprising one or more transmission antenna device(s) and one or more reception antenna device(s), the upper part and the bottom part being arranged movably in relation to each other, so that the bottom part, in use mode, is closer to a user than the upper part, wherein the bottom part comprises one or more reception antenna device(s) arranged to receive a polarization orthogonal to the polarization of the one or more reception antenna device(s) of the upper part, wherein the wireless communication device comprises a laptop, a notebook computer, a pocket or a personal computer, and wherein the bottom part does not compromise any transmission antenna device(s).

2. The wireless communication device as claimed in claim 1 , wherein the one or more reception antenna device(s) comprises a microstrip antenna.

3. The wireless communication device as claimed in claim 1 , wherein the one or more reception antenna device(s) and the one or more transmission antenna device(s) operate in a cellular communication frequency band.

4. The wireless communication device as claimed in claim 1 , wherein the upper part and the bottom part are pivotally or slidably fastened to each other.

5. The wireless communication device as claimed in claim 1 , wherein the upper part comprises a lid of a laptop and the bottom part comprises a user input device of the laptop.

6. The wireless communication device as claimed in claim 2 , wherein the microstrip antenna is configured as a planar inverted F antenna or a rectangular patch antenna.

7. A wireless communication device having an upper part and a bottom part, the upper part compromising one or more transmission antenna device(s) and one or more reception antenna device(s), the upper part and the bottom part being arranged movably in relation to each other, so that the bottom part, in use mode, is closer to a user than the upper part, wherein the bottom part compromises one or more reception antenna device(s) arranged to receive a polarization orthogonal to the polarization of the one or more reception antenna device(s) of the upper part, wherein all transmission antenna device(s) of the wireless communication device are located in said upper part, wherein the wireless communication device compromises a laptop, a notebook computer, or a pocket or personal computer.
