Summary:An assembly includes a wire antenna including at least on conductive turn, a first fibrous substrate on which the antenna extend. The first substrate comprises at least one coated paper including a fibrous base containing at least 30 mass % of natural fibers in the fibrous mass. The antenna is connected to a face of the flexible substrate. The paper includes on that face at least one surface layer containing at least one mineral load and a coating binder. The fibrous base may contain at least 40 mass %, preferably 50 mass %, more preferably 60 mass % and ideally at least 70 mass % of natural fibers, with preferably a lower proportion of long natural fibers relative to short ones when the fibrous mass includes synthetic fibers, in particular between 5 and 25% of synthetic fibers.
