Description
Technical field
The present invention relates to reading and writing device antenna field, especially a kind of Internet of Things UHF RFID circular polarisation reading and writing device antenna.
Background technology
At present, the antenna of read write line is the equipment launching and receiving radio-frequency carrier signal, but existing reading and writing device antenna structure design shortcoming reasonability, stability is the highest, identifies that distance is near, easily causes and read the problem that accuracy rate is low under being disturbed environment.
Summary of the invention
It is an object of the invention to provide a kind of Internet of Things UHF RFID circular polarisation reading and writing device antenna.
The existing reading and writing device antenna structure the being design shortcoming reasonability that the present invention solves, stability is the highest, identifies that distance is near, easily causes and read the problem that accuracy rate is low under complex environment.
The present invention solves its technical problem and the technical scheme is that the present invention includes Antenna baseplate, radiant panel and ballast cover；Described Antenna baseplate is square structure, and it is formed around flanging；Described radiant panel is square plate and is located in the space that described flanging encloses, and radiant panel utilizes the air gap insulating bolt to be fixed on Antenna baseplate and is provided with gap between radiant panel and Antenna baseplate；One diagonal of described radiant panel is provided with rectangular through slot；The 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 above Antenna baseplate.
The invention has the beneficial effects as follows: present configuration is reasonable in design, stability is high, identifies that distance is remote.The signal utilizing circular polarized antenna to make to induce is all identical so that the sensitivity of antenna bearingt is reduced by system.And circular polarized antenna electromagnetic property is good, and capacity of resisting disturbance is strong.
Antenna Design in the present invention can form the optimum impedance coupling antenna meeting ultra-high frequency band (902-928MHz), and identifies that distance is more than 8 meters.
Reading and writing device antenna of the present invention is utilized to realize people to each type objects or equipment (personnel, article)
Automatically identifying and management under different conditions (mobile, static or adverse circumstances), is suitable for the fields such as logistics management, gate control system.
