Abstract :
A wave absorber based on reinforced plastic including glass fiber with periodic lattice is proposed, the absorption and the shielding effect are examined at 5.8 GHz for ETC. As a result, the absorption of 10 dB or more can be obtained at the incident angle ranging from 5 to 55 degrees for circularly polarized wave. Furthermore, the shielding effect of 20 dB or more is also obtained. Therefore, realization of the wave absorber with periodic lattice for ETC is clarified.
