Abstract
The utility model discloses a UHF RFID linear polarization antenna, comprising an antenna base plate with a flanging, an insulation substrate and a radiant panel. A radio frequency connector lug is arranged on the back of the antenna base plate. The insulation substrate comprises a lower insulated panel, a middle insulated panel and an upper insulated panel. The radiant panel comprises a lower radiant panel and an upper radiant panel. The lower radiant panel is arranged on the lower surface of the lower insulated panel. The upper radiant panel is arranged on the upper surface of the upper insulated panel. The lower insulated panel, the middle insulated panel and the upper insulated panel are superposed from the bottom to the top and fixed on the antenna base plate through an insulation stud. A grounding needle is arranged on the insulation substratein a penetrating manner. The linear polarization antenna provided by the utility model has the characteristics of long identification distance and high reading accuracy.
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, decipherment distance is short, easily causes that to read accuracy rate low, omits the problem reading, can not improve management, thereby cause 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, and omission is read, and can not improve management, thereby causes the problem of unnecessary loss.
The technical scheme that the utility model solves its technical problem employing is: the utility model comprises Antenna baseplate, insulated substrate and the radiant panel with flanging; The back side of described Antenna baseplate is provided with radio-frequency connections head, and described insulated substrate comprises lower floor's insulation board, middle level insulation board and upper strata insulation board; Described radiant panel comprises lower radiant panel and upper radiant panel; Described lower radiant panel is located at the lower surface of lower floor's insulation board, and described upper radiant panel is located at the upper surface of upper strata insulation board; Described lower floor's insulation board, middle level insulation board and upper strata insulation board superpose from bottom to up and utilize insulating bolt to be fixed on Antenna baseplate; On described insulated substrate, be installed with grounding pin.
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.The utility model is applied to logistics management, production line, gate inhibition and passes in and out the fields such as system, vehicle management, and 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 be realized the optimum impedance coupling antenna that meets ultra-high frequency band (902-928MHz).
