DEVICE FOR RECEIVING AND/OR TRANSMITTING ELECTROMAGNETIC SIGNALS FOR USE IN THE FIELD OF WIRELESS TRANSMISSIONS.

摘要

The invention concerns a device for receiving and/or transmitting signals comprising at least two wave reception and/or transmission means consisting of a slot antenna (10, 11) and means for connecting at least one of said reception and/or transmission means to means using multibeam signals. The connection means consist of a common feeder line (12) the line being electromagnetically coupled with the slots of the slot antenna and being terminated by an electronic component enabling through a control signal to simulate a short circuit or an open circuit at the end of said line so that, when the component is in on-state the radiation pattern derived from the device is different from the radiation pattern derived from the device when the component is in off-state. The invention is applicable to the field of wireless transmissions.
