Abstract

In this paper, a novel miniaturized UHF Radio-Frequency Identification (RFID) tag dipole antenna is proposed. Its original structure consists on a series of parallel arms connected to a perpendicular line at their ends. This configuration allows decreasing the physical length of the dipole antenna. A short stub is used at the input to provide a flexible impedance tuning. Two antennas were designed with different sizes. The first antenna, designed for both North American and European bands, has a size of 76.5 mm times 16 mm. The second designed antenna operates in the North American band and has a size of 48.5 mm times 25.5 mm. The two antennas exhibit respective efficiencies of 85 per cent and 74 per cent, making them suitable for RFID applications.
