ABSTRACT:
The present invention relates to a radiating device intended to receive and/or transmit electromagnetic signals comprising at least two antennas connected by slot and having a common slot. Connection means enable at least one antenna to be connected to processing means of electromagnetic signals. The connection means include two connection lines connected to the processing means. The two lines are terminated by an open circuit and are coupled electromagnetically to the common slot of the two antennas so as to enable a phase difference to be introduced between the electromagnetic signals of the two antennas when the connection is switched from one line to the other by means of a switching device present on the connection lines.
