In this paper the evolution of the called “ChessBoard” structure to reduce RCS is presented. Initially, by combining PEC cells and AMC cells a single frequency RCS reduction is achieved. This narrow band limitation can be overcome by substituting the PEC by another AMC structure, guiding to a dual band behavior or a broadband one, with operational bandwidths around 40% of RCS reduction. Different cell configurations are being studied to be presented in the congress.
