Design of multilayered space filters using conductive film grid sheet and dielectric materials

Abstract

As the newly EMC materials, the authors have been proposed the bandpass space filters consisting the metal wire grid with negative relative permittivity and dielectric materials. In this study, the novel space filters using conductive film grid, instead of a metal wire grid, are proposed. Next, the transmission characteristics of the proposed space filters for a Wifi router in the 2.4GHz band or the 5.0GHz band are evaluated by the measurement in free space and the calculation of transmission line theory.
