Abstract
A tiny dual‐band frequency selective surface structure is proposed in this paper. With dual‐band rejection characteristics at the corresponding frequency points of the S‐band and C‐band, suitable for antenna stealth. To achieve miniaturization, the unit‐cell architecture resembles the shape of a “S.” First of all, the author describes the parameters of the surface element, and then, the transmission characteristics of the surface element are analyzed by the equivalent circuit method. By maintaining a constant response to TE and TM polarization patterns and oblique incident angles, the suggested device ensures angular independence. The measured findings from the constructed FSS are used to validate the computed results. Finally, a new unit structure is provided for the application of FSS in antenna stealth.Keywords
