The design of a frequency selective surface (FSS) screen constructed using a coupling configuration to implement a broadband microwave absorber is presented in this paper. The reflectivity representation recognizes the characterization of the absorber. Simulation and measurement results are presented and analyzed. A coupling FSS screen is introduced in order to obtain a better bandwidth and absorption. The bandwidth with the reflectivity below -10dB could get 5.52-18GHz, compared with the 6.52-18GHz of the absorber with square patches FSS, provided that the thickness of the absorber is 4mm.
