Abstract:Emerging use of passive Ultra‐High Frequency (UHF) Radio Frequency Identification (RFID) systems requires application‐specific tag antennas for challenging materials. The operability of folded microstrip patch‐type tag antenna affixed to objects containing conductive and liquid‐based materials is analysed and tested in the UHF RFID bands within 865 928 MHz. The performance of the antenna design using Electronic Product Code (EPC) Gen 1 and Gen 2 standards is also analysed. The results show that the antenna design is operable in the studied UHF RFID bands and its performance improves when Gen 2 standard is used.
