Abstract(in English) Recently, the use of the wireless system LAN and Bluetooth system is active. The indoor electromagnetic environment is deteriorated with an increase in the wireless system equipment. The electromagnetic radiation absorption wall is used in effective method of improving the indoor transmission environment. However, because the frequency sued for wireless system LAN is a plural, the RF absorption wall should absorb the electromagnetic radiation of two or more frequencies. Therefore, the electromagnetic radiation absorption wall with an excellent absorption characteristic for dual frequency band (2.4GHz and 5.2GHz) is proposed in this paper. It was confirmed to obtain the frequency selective of 2GHz band by the size and the position of the insertion metallic plate and show the reflection loss 20dB or more in the bandwidth used by the wireless LAN. In addition, the thickness of absorber achieved making of the thickness of about 50% thin at 2.4GHz band compared with λ/4 type wave absorber.
