Multi Wide-Band Frequency Selective Surface for Automotive Applications

A symmetrical double-layer frequency selective surface (FSS) is proposed for multi wide-band filtering applications. The structure consists of three pairs of circles on the two sides of the supporting dielectric layer. A parametric analysis concerning the frequency response versus the angle of incidence is reported., demonstrating that the structure exhibits a satisfactory response to incidence up to 45°, for both TE and TM cases. The configuration can be used for filtering in the X band for example in Automotive applications.
