Design of a paper-based reconfigurable frequency selective surface structure

Abstract

In this study, a paper-based reconfigurable frequency selective surface (FSS) that can be applied as wallpaper inside buildings to control the indoor spectrum was designed using the ink-jet printing method. The designed paper-based FSS uses a PIN diode to block 5 GHz band signals in the OFF condition and to transmit the signals in the ON condition, offering frequency characteristics stable to polarization and incident angles. To verify the operation of the designed FSS, the FSS was printed on a 0.2 mm thick paper using the ink-jet printing method by attaching a PIN diode using a conductive adhesive to manufacture the FSS with a switching function. It was confirmed that the measured frequency transmission characteristics according to the switching operation corresponded to the calculated results, and stability was exhibited for polarization and incident angles.
