Abstract:	A novel broadband design of a planar passive UHF-RFID tag based on a split-ring resonator (SRR) antenna and the T-match network is presented in this work. The radiation properties of the SRR working at its second resonance are exploited to design a radio frequency identification (RFID) tag for the first time. The potential usefulness of the T-match based design methodology to achieve perfect matching between the SRR antenna and any typical RFID chip is demonstrated. A 0. 23 λ₀ × 0. 23 λ₀ tag has been fabricated. The measured read range is higher than 13 m within the whole UHF-RFID band with a peak value of 16 m at 915 MHz.
