Development of environmental agreement type transparent thin microwave absorber to protect information

In this research, ultra thin microwave absorber as an improvement technology of the multi-path environment for UHF-RFID system is reported. Additionally, a transparent feature is given to this absorber. Because the microwave absorber should not increase the blind area of the observation camera in the region for which UHF-RFID system is used(around the entrance gate of offices or warehouses). In an actual warehouse, the verified result about the effectiveness of tag identification probability improvement with this absorber is also presented.
