Ultra high frequency RFID gateway system for identification of metallic equipment

Metallic equipment and objects require special attention for identification in a Radio Frequency Identification (RFID) system, due to their interference negative effects. This paper presents an application of ultra-high frequency RFID in a gateway configuration, used to identify metallic equipment. The main purpose of the proposed system is to identify items with metallic content and regardless of their position when passing through the gateway. The UHF (Ultra High Frequency) RFID technology with passive tagging was implemented. Different tagging configurations were tested and results for each configuration are presented.
