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) 12 a, 12 b; 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) 14 a, 14 b, 14 c, 14 d.

First claim

The invention claimed is:

1. A wireless communication device comprising:
a first part that comprises one or more transceiver antenna devices arranged to operate in a cellular communication frequency band, wherein one or more of said one or more transceiver antenna devices comprises a transmission antenna device and a reception antenna device; and
a second part that comprises one or more reception antenna devices arranged to operate in a cellular communication frequency band, wherein the first part and the second part are arranged movably in relation to each other, and any transmission antenna device that is included in the wireless communication device and that is arranged to operate in the cellular communication frequency band are located in the first part.

2. The wireless communication device of claim 1 , wherein the first part, in use mode, is closer to the user than the second part.

3. The wireless communication device of claim 1 , wherein
said one or more reception antenna devices included in the second part are arranged to receive a polarization orthogonal to the polarization of said one or more reception antenna devices included in the first part.

4. The wireless communication device of claim 1 , wherein said one or more reception antenna devices included in the second part comprises a microstrip antenna.

5. The wireless communication device of claim 4 , wherein the microstrip antenna is either a planar inverted F antenna or a rectangular patch antenna.

6. The wireless communication device of claim 1 , wherein the first part and the second part are pivotally or slidably fastened to each other.

7. The wireless communication device of claim 1 , wherein the wireless communication device is a mobile phone.

8. The wireless communication device of claim 1 , wherein the wireless communication device is a laptop.
