Abstract
The bandwidth of ultrathin sheet absorber in low frequency is difficult to broaden, therefore, high permeability material is introduced in this paper. Finally, it realizes to broaden the frequency bandwidth and simulation analysis is carried out. At last, the absorption rate of the absorber between 1.15GHz and 2.37GHz is more than 90% with the thickness of 2.4mm and the absorber is insensitive to polarization and achieves high absorption rate in wide incidence angle.
