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 transceiver antenna device(s) wherein one or more of the transceiver antenna device(s) comprises a transmission antenna device and a reception antenna device, 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 the user than the upper part, wherein the bottom part comprises one or more reception antenna device(s) and wherein all transmission antenna device(s) of the wireless communication device are located in the upper part.

2. The wireless communication device as claimed in claim 1 , wherein transmission frequencies and reception frequencies are separated by one of a duplex filter and a switch being connected between transmission circuitry, reception circuitry and the transceiver antenna device.

3. The wireless communication device as claimed in claim 1 , wherein the one or more reception antenna device(s) comprises a microstrip antenna such as a planar inverted F antenna or a rectangular patch antenna.

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

5. 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.

6. The wireless communication device as claimed in claim 1 , wherein the wireless communication device is a mobile phone.

7. The wireless communication device as claimed in claim 1 , wherein the wireless communication device is a laptop.

8. The wireless communication device as claimed in claim 7 , wherein the upper part comprises the lid of a laptop and the bottom part comprises the user input device of the laptop.
