A compact and tunable ultra-high frequency (UHF) radio frequency identification (RFID) tag antenna is proposed. The antenna comprises a rectangular ring, two symmetrical radiating arms formed by multiple L-shaped stubs, and two interdigitated structures. By adjusting the parameters of double interdigitated structures, the resonant frequency of the antenna can be tuned coarsely and finely, while maintaining a nearly constant maximum power transmission coefficient. The proposed tag antenna has a size of 28 mm × 16 mm (0.086λ×0.049λ at 920 MHz). Measurement results show that the proposed antenna can achieve the maximum reading distance of 6.8 m at 920 MHz under the condition of 3.28 W effective isotropic radiated power. The proposed RFID tag antenna offers several advantages, including compact size and frequency tunability, making it well suited for various RFID system applications. [ABSTRACT FROM AUTHOR] |
