Frequency selective surfaces with non fractal geometry

Abstract

The use of FSS with non fractal geometry is proposed in this work. When non fractal details are applied to rectangular patch, the FSS frequency response can be drastically affected. The frequency of resonance can be reduced and new resonance can be obtained. Furthermore, the bandwidth between resonances can be modified. Then, these characteristics can be utilized to design FSS with multiband operations or to reduce the FSS dimensions. In this work, numerical results, obtained using the WCIP method, are presented and discussed to different FSS with non fractal geometry. Two FSS with non fractal geometry are characterized experimentally and the obtained results compared to numerical ones. The results indicate the potential of the non fractal geometry in the FSS design, which instigate the research for new applications.
