Development of Thin Electromagnetic Wave Absorption Wall using Patch Elements
Wireless telecommunication devices such as mobile phones, wireless LANs (2.45 GHz, 5.2 GHz) and UHF radio frequency identification (UHF-RFID) systems have proliferated all over the world. Therefore, electromagnetic interference (EMI) problems have increased. In indoor use, the wireless telecommunications environment can deteriorate due to multiplex reflection interference. This interference must be suppressed to improve wireless communications. Therefore, establishment of a multiplex reflection interference suppression technology is needed. In this study, a convenient, thin EM wave absorption wall was developed. The practicality of this wall was verified through the experimental results of a prototype absorption wall and the calculated results of a finite-difference time-domain (FDTD) numerical analysis. The proposed thin EM absorption wall and the verification results are described in this paper.
