The present invention relates to a device for receiving and/or transmitting electromagnetic waves with radiation diversity. This device comprises, on a common substrate, at least one antenna of the slot type formed by a closed curve, known as a slot antenna, electromagnetically coupled to a first supply line, and an antenna radiating parallel to the substrate, positioned inside the slot antenna and connected to a second supply line, said first and second supply lines being connected via a switching means to means for exploiting the electromagnetic waves. The device can be applied, in particular, in the field of wireless transmissions.

The invention relates to a device for receiving and/or transmitting electromagnetic signals comprising three annular slots (20, 21, 22) which are tangent in pairs at two points P1 and P2. These slots are supplied by two supply lines (23, 24) so as to produce a line/slot transition. One of the lines 23 passes through the point P1 while the other line 24 passes through the point P2, the two lines being connected via a T-shaped junction at a common port 1. A diode 25 or 26 is mounted at the free end of each line, making it possible to simulate a short circuit or an open circuit at the end of one of the lines and an open circuit or a short circuit at the end of the other line.

The invention relates to a planar antenna realised on a substrate (2) comprising a slot (1) of closed form dimensioned to operate at a given frequency in a short-circuit plane of at least one feed-line (3, 4). In this case, the perimeter of the slot is designed such that p=kλs where k is a whole number greater than 1 and λs the guided wavelength in the slot. On the other hand, it comprises at least one first feed-line (3) placed in an open circuit zone of the slot and a second feed-line (4) placed at a distance d=(2n+1) λs/4 from the first line, where n is an integer greater than or equal to zero. The invention is particularly applicable to wireless transmissions.

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.

The present invention relates to an antenna system designed to be used in a wireless link, having polarization directions, respectively for reception and emission identical to the polarization directions, respectively for emission and reception, presented by a similar system placed in a geometric configuration of use that is different from that of the said first system. The invention enables identical devices to be implemented in separate items of equipment and in distinct positions while enabling the antenna pair to function correctly.
