Abstract
The utility model discloses a UHF RFID linear polarization antenna, comprising an antenna base plate with a folding edge, an insulation base material and an E-type radiant plate. A radio frequency connector lug is arranged on the back of the antenna base plate. The insulation base material is of square block structure, and fixed on the antenna base plate through an insulation bolt. The E-type radiant plate is arranged on the surface of the insulation base material. The end, fixed on the back of the antenna base plate, of the radio frequency connector lug is a joint for the signals to be inputted and outputted and the other end of the radio frequency connector lug traverses the insulation base material and is welded on the E-type radiant plate. The linear polarization antenna provided by the utility model is characterized by long identification distance, and high reading accuracy and is not easy to omit.
Description
Technical field
The utility model 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.
Utility model content
The purpose of this utility model is to provide a kind of UHF RFID linear polarized antenna.
What the utility model 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 utility model solves its technical problem employing is: the utility model comprises Antenna baseplate, insulating substrate and the 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 beneficial effects of the utility model are: it is far away to the utlity model has decipherment distance, reads the feature that accuracy rate is high.Be applied to logistics management, production line, gate inhibition and pass in and out the field such as system, vehicle management, the utility model can read one by one and identify the mobile people in these fields or article, is difficult for causing careless omission phenomenon.
The utility model can form the antenna of the optimum impedance coupling that meets ultra-high frequency band (902-928MHz).
