摘要： Planar antenna carried by a substrate comprising an annular slot, which is dimensioned to operate at a given frequency and which is fed via a line (2), such as a microstrip line, in a short-circuit plane of which the slot is situated.
The annulus formed by this slot (1a), is deformed as indentations in at least one zone of the plane in which the electric field is a minimum for the given frequency and a given mode, this making it possible to obtain a lengthening of the slot perimeter with respect to an annular slot (1) of corresponding circular shape, without surface extension of the substrate zone wherein the slot is made.

摘要： The present invention relates to a device for the reception and/or the transmission of electromagnetic signals comprising at least two means of reception and/or of transmission of electromagnetic signals of the slot-fed antenna (11a, 11b, 11c, lid) type and means of connection for connecting at least one of the said means of reception and/or of transmission to means of utilization of the multibeam signals, in which the means of connection consist of two feed lines (12, 13) connected by a connection element to the utilization means (P), the two lines being coupled electromagnetically with the slots of the slot-fed antennas, each line terminating in a switching element (14, 15) arranged in such a way as to simulate, as a function of a monitoring signal, an open circuit or a short circuit at the extremity of one of the lines and a short circuit or an open circuit at the extremity of the other line so as to obtain different radiation patterns.
