A Low Cost Solution for the Realisation of Finite Planar Frequency Selective Shields

This work introduces a low cost solution for the realization of frequency selective spatial filters for wireless applications. The paper illustrates a complete solution to model, design and measure the frequency behaviour of these devices. In particular, an experimental setup that takes into account real case installations is described. To demonstrate the validity of the application, some prototypes were designed, manufactured and measured. All realizations were perfectly transparent to light propagation and offered good selective multiband rejection to microwaves.
