Abstract
The utility model provides a flexible UHF-RFID reader-writer antenna. The flexible UHF-RFID reader-writer antenna uses a metallic thin belt as a core. A nonmetallic insulating protection layer is combined on the surface of the metallic thin belt. The flexible UHF-RFID reader-writer antenna is soft and can be folded arbitrarily. According to specific application, the antenna with required length is cut and is pasted on the surface of another object or is embedded into the object in order to form the antenna of an UHF-RFID label reader-writer. By the above structure, UHF-RFID engineering application products can be easily and flexibly designed and produced and a product experiment environment can be easily and flexibly established. In the case of the engineering design and assembly of a strip-shaped antenna in a metallic totally-enclosed cabinet, the flexible UHF-RFID reader-writer antenna has practicability. In addition, in the aspect of industrial manufacture of engineering products, the flexible UHF-RFID reader-writer antenna also has positive effects.
Description
Technical field
The utility model relates to a kind of flexible UHF-RFID reading and writing device antenna, specifically, relates to a kind of for the stripline antenna in the metal all-closed bin.
Background technology
The UHF-RFID reading and writing device antenna plays a key role in label and read write line data communication process, and on the one hand, the chip enable circuit of label is started working, and needs to obtain enough energy by its antenna in the electromagnetic field that read write line produces; On the other hand, reading and writing device antenna has determined the quality of communication channel between label and the read write line.
Under normal conditions, the read-write of electronic tag in a complex environment, wherein the antenna of read write line and setting are actually an engineering problem, especially in the space that radio-wave reflection broken line background is arranged.For example in metal all-closed environment, the radio wave that read write line is launched at its antenna, in above-mentioned environment, can produce unsettled cavity resonance effect, when producing interference noise, consume lot of energy, thereby form erratic blind area, these situations will reduce the discrimination of electronic tag greatly.
In addition, radio wave has such characteristic, when frequency and amplitude all two train waves identical, that direction of vibration is consistent, the direction of propagation is opposite can superpose and form new ripple.Its waveform was constantly pushed ahead when ripple was propagated in medium, so claim the row ripple; Above-mentioned two train waves stack back waveform is not pushed ahead, so claim standing wave, namely is the hole of radio wave at the annex of standing wave point, states in the hole as if the positive place of electronic tag, and then read write line can't be done read-write operation to this label.
Up to the present, the UHF-RFID reading and writing device antenna when product runs into the radio wave applied environment of described complexity, can not effectively solve engineering problem based on the fixing microstrip antenna of specification.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of flexible UHF-RFID reading and writing device antenna, in the radio wave applied environment of complexity, engineering set-up mode by special-shaped antenna, establish the application solution of UHF-RFID tag recognition targetedly, make its more positive effect of performance in Internet of Things is used.
The flexible UHF-RFID reading and writing device antenna that the utility model provides is characterised in that: it is core that flexible UHF-RFID antenna adopts metal sheet band, the nonmetal insulating protective layer of surface recombination.
Flexible UHF-RFID reading and writing device antenna provided by the utility model has the characteristics of softness, random bending fold owing to its structure.
Described metal sheet band in the flexible UHF-RFID reading and writing device antenna described in the utility model has good electrical conductivity and ductility, can be copper, aluminium or their composite material.
Flexible UHF-RFID reading and writing device antenna described in the utility model is characterized in that: described surface recombination protective layer, be non-metal insulating material, and insulating properties is strong, and good stretch-resistance is arranged, and is covered in described metal sheet band surface fully.
Flexible UHF-RFID antenna of the present utility model, in actual applications can be convenient, flexible design and produce UHF-RFID engineering application product, build the product testing environment, especially at engineering design and the assembling of stripline antenna in the metal all-closed bin, have more practicality; And described flexible UHF-RFID reading and writing device antenna at engineering product industrialization manufacture view, also can be brought into play positive effect.
