A printed two‐dipole array antenna with a high front‐back ratio is proposed for ultra‐high‐frequency (UHF) radio‐frequency identification handheld readers. The proposed antenna is a parasitic dual‐element array with the ends of both elements folded back towards each other for additional coupling. The antenna features a compact size of 89 mm × 87 mm and works properly with satisfactory gain and total efficiency in the wide UHF band of 860–960 MHz. Furthermore, the front‐to‐back ratio of 15–26.8 dB, the peak gain of 3.7–4.4 dBi and the total efficiency of more than 80% in the Federal Communication Commission (FCC) band make the proposed antenna attain high performance in the FCC band.
