This paper presents a novel RFID tag antenna for metallic objects.This antenna contains a coupling ground and wing-shape radiation patch.The antenna has the compact size of 84 mm×25 mm×4.5 mm.If the Circularly polarized reader antenna gain is 7.5 dBi,the radiated power is 30dbm,the reading distance can be reached to 10 m in 902~928 MHz range.The measured results indicate that the tag antenna has a good long-range recognition performance on the surface of the metal objects.

Key words: tag antenna;anti metal;coupling structure
