Dual-band UHF RFID tag for metallic items

This work presents a UHF RFID tag mounted on metallic objects operating in the European and American frequencies (866 and 915 MHz). It is based on a modified patch antenna with a planar structure without the need to shorting pins or holes for a low cost, a very simple and inexpensive manufacturing process with a promising read range of 11m and 9.7m at 866 MHz and 915 MHz respectively
