Abstract


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.
