Abstract
The invention discloses a UHF RFID linearly-polarized antenna which comprises an antenna base plate with flanges, an insulating base material and an E-shaped radiating plate, wherein the back side of the antenna base plate is provided with a radiofrequency connecting lug, the insulating base material includes a square block structure, and is fixed to the antenna base plate via insulating bolts, and the E-shaped radiating plate is arranged at the surface of the insulating base material. The end, which is fixed to the back side of the antenna base plate, of the radiofrequency connecting lug includes a signal input and output joint, and the other end of the radiofrequency connecting lug is welded onto the E-shaped radiating plate. The UHF RFID linearly-polarized antenna is characterized by long identification distance and high reading accuracy, and tends not to cause oversight.
Description
Technical field
The present invention relates to field of antenna, especially a kind of UHF RFID linear polarized antenna.
Background technology
At present, RFID technology is widely used in the fields such as logistics management, production line, gate inhibition's turnover system, but existing antenna structure, and decipherment distance is short, easily causes that to read accuracy rate low, omits the problem reading, thereby causes unnecessary loss.
Summary of the invention
The object of this invention is to provide a kind of UHF RFID linear polarized antenna.
What the present invention solved is existing antenna structure, and decipherment distance is short, easily causes that to read accuracy rate low, omits the problem reading.
The technical scheme that the present invention solves its technical problem employing is: the present invention includes Antenna baseplate, insulating substrate and E type radiant panel with flanging; The back side of described Antenna baseplate is provided with radio-frequency connections head; Described insulating substrate is square block structure, utilizes insulated bolt to be fixed on Antenna baseplate; Described E type radiant panel is located at the surface of insulating substrate; One end that described radio-frequency connections head is fixed on the Antenna baseplate back side is the joint of signal input and output, and the other end is welded on type radiant panel through insulating substrate.
The invention has the beneficial effects as follows: it is far away that the present invention has decipherment distance, read the feature that accuracy rate is high.Be applied to logistics management, production line, gate inhibition and pass in and out the fields such as system, vehicle management, the present invention can read one by one and identify the mobile people in these fields or article, is difficult for causing careless omission phenomenon.
The present invention can form the antenna of the optimum impedance coupling that meets ultra-high frequency band (902-928MHz).
