Confering to a wallpaper electromagnetic filtering capacities is an interesting way to answer to the increasing demand of isolation from electromagnetic waves. In this article, we demonstrate the feasibility of such a product with flexographic conductive ink printing. Prototypes samples with novel frequency selective surface patterns show insensibility to the polarization and to the angles of incidence. Measured attenuation levels of 21 and 22 dB are obtained with a prototype-sample produced with a industrial printing machine. Two frequencies rejection well adapted to WiFi applications and three frequencies adapted to GSM applications can be realized.
