Abstract (en)
[origin: WO2018011294A1] This device comprises a substrate, a network of elementary conductive patterns (8) printed on a surface of said substrate, and a network of coupling components (12, 12a, 12b), each connecting two adjacent elementary conductive patterns (8) and having a modifiable capacitance. The device comprises a control assembly for selectively controlling the value of the capacitances of groups (20a, 20b) of coupling components (12, 12a, 12b) according to a first band-stop mode, in which the capacitance of the assembly of groups (20a, 20b) is fixed at a given value, and a second band-pass mode, in which the capacitance of the coupling components (12, 12a, 12b) of a first assembly of groups (20a) is fixed at a first value, and the capacitance of the coupling components (12, 12a, 12b) of a second assembly (20b) of groups, complementary to the first assembly, is fixed at a second value.
