EM performance analysis of double square loop FSS embedded C-sandwich radome

Double square loop frequency selective surface (DSL-FSS) for the broadbanding of C-sandwich radome is presented. Equivalent transmission line method in conjunction with equivalent circuit model is used for the EM performance analysis of aperture type double square loop embedded C-sandwich radome. EM analysis shows that the DSL-FSS embedded C-sandwich radome panel has superior performance parameters as compared to C-sandwich alone.
