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, decipherment distance is short, easily causes that to read accuracy rate low, omits the problem reading, can not improve management, thereby cause 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, and omission is read, and can not improve management, thereby causes the problem of unnecessary loss.
The technical scheme that the present invention solves its technical problem employing is: the present invention includes Antenna baseplate, insulated substrate and 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 superposes from bottom to up and utilizes insulating bolt to be fixed on Antenna baseplate; On described insulated substrate, be installed with grounding pin.
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.The present invention is applied to logistics management, production line, gate inhibition and passes in and out the field such as system, vehicle management, and 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 realize the optimum impedance coupling antenna that meets ultra-high frequency band (902-928MHz).
