Abstract
The utility model discloses an ultrahigh-frequency long-distance reader-writer antenna, comprising an antenna base plate with a folding edge, a base radiant plate and a radiant plate. The base radiant plate comprises a square plate and a connection bridge. The base radiant plate and the radiant plate are fixed on the antenna base plate through an air interval insulation stud. Grounding needle is arranged at the center of the antenna base plate, the base radiant plate and the radiant plate. The connection bridge surrounds one corner of the square plate in an L-shape. An extension segment is arranged on one edge of the connection bridge. A radio frequency coaxial connector is disposed on the folding edge of the antenna base plate. A radio frequency connector lug is disposed on the radio frequency coaxial connector. The radio frequency connector lug traverses the folding edge and is in welding fixation with the extension segment. The antenna of the utility model is capable of realizing multi-path identification and reading, and enlarging identification scope and has the characteristic of long-distance automatic identification.
