Abstract
The utility model discloses a UHF RFID circular polarization reader-writer antenna of Internet of things. The antenna comprises an antenna base plate, a radiant panel and a ballast cover. The antenna base plate is of a square structure and is provided with flanging all around. The radiant panel is a square panel and arranged in an enclosed space of the flanging. The radiant panel is fixed on the antenna base plate through an air gap insulation stud and a gap is provided between the radiant panel and the antenna base plate. A rectangular groove is arranged on one diagonal of the radiant panel. A grounding needle is arranged on one side of the rectangular groove. A radio frequency connector lug is fixedly arranged on the back of the antenna base plate. The ballast cover covers above the antenna base plate. The antenna of the utility model is strong in anti-interference capability, and long in identification distance and is accurate to read the signals.
Description
Technical field
The utility model relates to reading and writing device antenna field, especially a kind of Internet of Things UHF RFID circular polarization reading and writing device antenna.
Background technology
At present, the antenna of read write line is the equipment that transmits and receives radio-frequency carrier signal, but existing reading and writing device antenna structural design shortcoming reasonability, and stability is not high, and decipherment distance is near, easily causes the problem that accuracy rate is low that reads being disturbed under environment.
Utility model content
The purpose of this utility model is to provide a kind of Internet of Things UHF RFID circular polarization reading and writing device antenna.
The existing reading and writing device antenna structural design shortcoming reasonability that is of the utility model solution, stability is not high, and decipherment distance is near, easily causes the problem that accuracy rate is low that reads under complex environment.
The technical scheme that the utility model solves its technical problem employing is: the utility model comprises Antenna baseplate, radiant panel and ballast cover; Described Antenna baseplate is square structure, and its surrounding is provided with flanging; Described radiant panel is square plate and is located in the space that described flanging encloses, radiant panel utilize air gap insulating bolt to be fixed on Antenna baseplate and radiant panel and Antenna baseplate between be provided with gap; A diagonal of described radiant panel is provided with rectangular through slot; One side of described rectangular through slot is provided with grounding pin; The back side of described Antenna baseplate is installed with radio-frequency connections head; Described ballast cover covers in Antenna baseplate top.
The beneficial effects of the utility model are: the utility model reasonable in design, and stability is high, and decipherment distance is far away.It is all identical utilizing circular polarized antenna to make the signal inducing, and system is reduced the susceptibility of antenna bearingt.And circular polarized antenna electromagnetic property is good, and antijamming capability is strong.
Antenna Design in the utility model can form the optimum impedance coupling antenna that meets ultra-high frequency band (902-928MHz), and decipherment distance is greater than 8 meters.
Utilize reading and writing device antenna described in the utility model to realize people's automatic identification and management under different conditions (mobile, static or adverse circumstances) to each type objects or equipment (personnel, article), be suitable for logistics management, the fields such as gate control system.
