Abstract
In this paper, an absorptive frequency selective surface with a wide high selective passband and two absorption bands is proposed. The absorptive frequency selective surface, is formed by generating two absorption bands besides the broadband transmission bands. The resistive layer and FSS layer consist of a wideband absorber and frequency selective surface respectively. It is shown by full-wave simulation that the structure has a 3dB transmission window from 7.8 to 12 GHz with a 42.4% fractional pass-bandwidth. And from 4 to 16.5GHz, the reflection coefficient can be reduced to −10dB.
