Abstract
In this paper, we designed and fabricated EM wave absorbers using Sendust, $Al(OH)_3$ and CPE(Chlorinated Polyethylene). We compared the absorption properties of samples containing 0 wt.%, 3 wt.%, 5 wt.%, 7 wt.% of $Al(OH)_3$. The optimized composition ratio of $Al(OH)_3$ is 5 wt.%, and the absorption property curve just has the tendency to improve at 5 wt.% of $Al(OH)_3$. And we used this characteristics to design the double-layered EM wave absorber. The double-layered EM wave absorber has thickness of 2 mm and has absorption ability more than 18.5 dB at a wireless LAN frequency band using 2.4 GHz.
