A novel miniaturized UHF RFID tag antenna (26.4 × 24 × 1.6 mm 3 ) for broadband operation over the UHF RFID band with good read range characteristics are proposed. The tag consists of a T‐matched dipole antenna with tapered meandered arms whose ends are folded to one side and an RFID chip is connected to the terminals of the antenna. The resonant frequency can be tuned by varying the gap width between the folded arms so that maximum read range can be achieved in the required territory's allotted band, without affecting its overall size. The measured read range variations with angular ranges for the proposed tag designed for maximum read range at 915 MHz are also presented. © 2017 Wiley Periodicals, Inc.
