Study Regarding the Influence of the Biasing Network in Designing a Switchable Frequency Selective Surface

In this paper some hints on the design of a switchable Frequency Selective Surface are proposed. The simulations of two distinct metallic constructions are performed, initially with no control network present and afterwards with control network (having the function to bias the active components inside the unit cells). The suggested designs have been evaluated using electromagnetic simulation. Different filtering bands are obtained below 12 GHz using the periodicity of the square-shaped unit cell with an 18 mm edge length.
