The utility model discloses a central concentrated load short circuit wire symmetry dipole tag antenna, comprising a substrate; a dipole, a short circuit wire and an IC welding position are printed on the substrate; one end of the dipole is connected with the IC welding position, the other end is an open circuit, the two dipoles are connected by the short circuit wire at one end around the IC welding position; the whole tag antenna is bilaterally symmetrical with the symmetry axis which passes through the center of the IC welding position and is vertical to the feed transmission line. The utility model is convenient to adjust the input impedance of the tag antenna due to the loaded short circuit for making the tag antenna better matching with a radio frequency tag chip impedance conjugate, realizing the maximum transportation of energy, and thereby effectively improving the tag recognition distance, the recognition distance is over 10 meters after matching with the radio frequency tag chip. The utility model is applicable for railcar management, aviation passenger and freight transportation, highroad vehicles management, logistics, propagation breeding management, archives management, access control system, security and safeguard, anti-fake labels, etc.
