ANTENNA SYSTEM HAVING A RADIATING DIAGRAM RECONFIGURABLE FROM SECTORIAL AND DIRECTIONAL RADIATING DIAGRAMS, AND CORRESPONDING TRANSMITTER AND/OR RECEIVER DEVICE

摘要

The invention relates to an antenna system having a radiating diagram that can be reconfigured from a set of diagrams including, for at least one plane associated with a given azimuth direction, at least one directional radiating diagram in said plane and at least one sectorial radiating diagram in said plane. The system includes a plurality of source antennas (74) and a reconfiguration means for switching from one diagram to another in said set of radiating diagrams. The reconfiguration means includes a means (702) for managing the power supply of the source antennas and a dielectric lens (701) focusing the radiation of the powered source antennas. The means (702) for managing the power supply of the source antennas generates a plurality of supply configurations each associated with a radiating diagram distinct from the set of radiating diagrams. The plurality of supply configurations includes, at least for a plane associated with a given azimuth direction: at least a first configuration associated with the directional radiating diagram in said plane, in which N source antenna(s) contained in said plane is/are powered, with N = 2; and at least a second configuration associated with a sectorial radiating diagram in said plane, in which N' source antennas contained in said plane are powered, with N' > N.
