Abstract
AbstractIn this paper, we proposed a dual‐band complementary frequency selective surface (CFSS) with narrow stop band and large stop band. The proposed CFSS combines two simple geometries, the square loop with grid and the crossed dipole. The resonant frequencies are 2.53 and 5.38 GHz. The bandwidths of 280 MHz and 1.77 GHz were obtained, at –10 dB level, for the first and second bands, respectively. These frequencies and bands show that the structure can be applied in Wi‐Fi (2.4–2.5 GHz) and C‐band (4–6 GHz) frequencies. The simulated and measured results show that the chosen geometry has angular stability and polarization independence up to 45°. We can observe a good agreement between simulated and measured results.
