UHF RFID transponders antenna design for metal and wood surfaces

Abstract

In this paper, metal and wood support effect on UHF RFID transponders are investigated. New antennas designed for passive UHF RFID transponders mounted on metal and wood surfaces are described. Simulation results are presented which are in good agreement with measurement data. The transponder reading distance measurement shows good performance. In particular the reading distance obtained with the tags designed for metal surfaces is higher compared to the available commercial Metal Mount UHF tags.
