Summary:The invention discloses an RFID tag antenna comprising a first antenna and a second antenna. The distance between the first antenna and the second antenna can be adjusted telescopically. The reading distance of the RFID tag antenna is long, and test shows that the reading distance can be up to 11-13m. The RFID tag antenna is stretchable and length-adjustable, and can be used in a complete set of package of which the width is basically fixed and the length is not fixed. The RFID tag antenna has great practical values, good antenna performance, low standing wave ratio, low return loss and high gain, and is omnidirectional.
