This article proposes a design of the 2.45‐GHz radio frequency identification tag antenna with a small size of 30 × 7.3 × 0.5 mm 3 . The proposed antenna consists of two radiating elements: one is a combination of the first‐order Hilbert fractal structure and the folded dipole; the other is the bent dipole. The interaction between two radiating parts makes the proposed antenna a 150 MHz broad bandwidth covering 2.37–2.52 GHz and a 2‐dB gain across the operating frequency band. Simulated and measured results validate the good performance of the proposed tag antenna. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1905–1908, 2015
