Abstract

This paper presents the development of a frequency selective surface, FSS, with three bands of rejection, with the central bandwidth applied to the 2.4 GHz frequency band. The three rejection bands are obtained from the association of crossed- dipoles and matryoshka ring geometries. For each geometry the initial design equations are proposed. The procedure to obtain the matryoshka geometry is described step by step. Numerical results are presented for each geometry, and also to the associated   geometries, considering different incident angles (θ=0°,15°,30° and 45°). The current distribution of each resonant frequency was shown, allowing to visualize the respective excited geometry. After the numerical results, we verify that the resonant frequencies associated to the respective geometry remains practically unchanged even for the associated geometries. A FSS prototype with the associated geometries was designed, fabricated, and characterized, with a very good agreement between numerical and experimental results, obtaining an attenuation of at least 15 dB in the 2.4 GHz frequency band.
