A Planar Dual-Band UHF RFID Tag for Metallic Items
Résumé
In this paper, a comparison of three tags based on modified patches for UHF RFID in term of size and read range performance is proposed. The antenna structure consists of a patch with an open stub and meander line for feed. The tags are dedicated to being mounted on metallic items and to operate on dual-band frequencies (European and American UHF RFID frequency bands). Moreover, the structure of the antennas is planar without any via holes or multilayers for a low cost and easy fabrication. Good agreement between simulation and experimental results has been obtained at 866 MHz and 915 MHz.
