Vorrichtung mit einstellbarer frequenzselektiver Oberfläche

摘要

The subject of the invention is a device with frequency-selective surface including at least one network (1) of conducting elements constituting elementary patterns (2). According to the invention, the device includes coupling means (4) between the conducting elements, selected and controlled by control means (3) so as to modify the apparent dimension of the patterns, thereby rendering the selective network tunable within a wide frequency range, these coupling means (4) including a first series of electronic components (44), a second series of electronic components (45) making it possible to actuate the components of the first series and to monitor their conduction, the components (45) of the second series being connected by at least one addressing wire (41, 42) to the control means (3).
