Abstract
A broadband 90 polarization rotator frequency selective surface (FSS) based on substrate integrated waveguide (SIW) technology is introduced in X band. Bandwidth enhancement is provided by two kinds of perturbation in the square SIW cavity. This is achieved by placing a metallic via at the center of the cavity and slanted via edge in the corners. The proposed structure is numerically investigated by CST software and the obtained results show the structure exhibits a relative impedance bandwidth of 12% (8.52 - 9.61 GHz) with a maximum insertion loss of 0.65 dB. Co-polarized reflection coefficient is less than -10 dB in the operating bandwidth.
