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.
