Design of V-shaped Salisbury Screen Absorber

Abstract

This paper proposed a V-shaped absorber based on Salisbury screen. Its innovation lies in the PEC ground inclined 45° and the vertical resistive sheet. This design makes the distance between the PEC ground and the resistive sheet not a unique value, which greatly widens the absorption bandwidth. The singlepolarization simulation results show that the single resistive sheet V-shaped absorber has an absorption bandwidth of 14.8-30 GHz (67.9%) with S11 <-10 dB approximately, and the triple resistive sheet V-shaped absorber has an absorption bandwidth of 2.86-30 GHz (165.2%). Finally, we demonstrated the 3D model of the foldable V-shaped Salisbury Screen absorber.
