Abstract

The invention is related to a communication device and a method for wireless signal transmission. An interference reduction means is arranged in between a transmitting path and a receiving path. The interference reduction mean is a wideband interference reduction means which converts a signal from said transmitting path into an anti-phased signal to provide the anti-phased signal to said receiving path.

First claim

1 . A communication device for wireless signal transmission,
wherein an interference reduction means is arranged in-between a transmitting path and a receiving path; and wherein the interference reduction means is a wideband interference reduction means which converts a signal from said transmitting path into an anti-phased signal to provide the anti-phased signal to said receiving path.

2 . The communication device according to claim 1 , further comprising at least a transceiver, wherein said transceiver comprises said transmitting path and said receiving path and wherein said transceiver further comprises a common antenna for a wireless signal transmission to external devices.

3 . The communication device according to claim 1 , comprising a plurality of transceivers in a common housing of the communication device,
wherein said transmitting path is a transmitting path of a first transceiver and said receiving path is a receiving path of a second transceiver and wherein said transmitting path is also a transmitting path of the second transceiver and said receiving path is also a receiving path of the first transceiver.

4 . The communication device according to claim 3 , wherein an antenna of the first transceiver is arranged in spatial proximity to an antenna of the second transceiver.

5 . The communication device according to claim 1 , wherein the interference reduction means comprises an attenuation module.

6 . The communication device according to claim 1 , wherein the propagation delay of the interference reduction means is equal to the propagation delay between the transmitting path and the receiving path.

7 . The communication device according to claim 1 , wherein the interference reduction means comprises a transformer, wherein the winding direction of a first winding is opposite to the winding direction of a second winding.

8 . The communication device according to claim 1 , wherein the interference reduction means comprises at least an inverting amplifier means.

9 . The communication device according to claim 1 , wherein the interference reduction means comprises a micro strip arrangement.

10 . The communication device according to claim 9 , wherein the micro strip arrangement comprises resistance elements.

11 . The communication device according to claim 9 , wherein the micro strip arrangement comprises a defected ground structure.

12 . The communication device according to claim 9 , wherein the micro strip arrangement comprises a Z-structure or a double-Z-structure.

13 . The communication device according to claim 1 , wherein the interference reduction means comprises a frequency adjusting means.

14 . The communication device according to claim 1 , wherein a combining element is used to combine said transmission path and said receiving path in a transceiver.

15 . A method for wireless signal transmission with a communication device, the method comprises the steps of:
providing a signal to a transmission path of said communication device; converting the signal into an anti-phased signal by an interference reduction means, wherein the interference reduction means is a wideband interference reduction means; and providing the anti-phased signal to a receiving path of the communication device.

16 . The method according to claim 15 , wherein the signal is provided by a first transceiver of the communication device and wherein said transmitting path is part of the first transceiver and wherein said receiving path is part of a second transceiver arranged in the communication device.

17 . The method according to claim 15 , wherein the communication device is a communication device for wireless signal transmission, wherein:
an interference reduction means is arranged in-between a transmitting path and a receiving path; and the interference reduction means is a wideband interference reduction means which converts a signal from said transmitting path into an anti-phased signal to provide the anti-phased signal to said receiving path.

18 . The method according to claim 15 , further comprising combining the transmission path and the receiving path in a transceiver.
