Abstract

In recent years, UHF- radio-frequency identification (RFID) systems are paid to attention as one of technologies which achieve the unattended shop or production field. However, the reliability of indoor telecommunication is adversely affected by multiple reflection interference. In order to actualize those unattended systems, the microwave absorber that suppresses the electromagnetic interference is essential. However, because existing microwave absorbers are not transparent, it blocks the monitoring camera's field of view. Therefore, flexible, transparent microwave absorber to improve the freedom degree of construction is developed, and evaluated results of the absorption performance are described in this report.
