Abstract

Recently, wireless telecommunication devices have been used with worldwide spread of the mobile phone, wireless LAN (2.45GHz, 5.2GHz) and UHF-RFID. Therefore, EMI (Electro Magnetic Interference) problems have been so serious. In the case of indoor use, wireless telecommunication environment is deteriorated by multiplex reflection interference. That interference has to be suppressed for improving wireless communication circumstance. Therefore, establishment of multiplex reflection interference suppression technology is needed. Thus, handy EM wave absorption wall of the thin type is developed, and it is reported. Additionally, a lightweight, thin EM wave absorber is experimentally fabricated, and the result of verifying practical use is shown in this report too.
