Abstract
The utility model relates to a bent slot antenna for an ultrahigh-frequency radio-frequency tag. The bent slot antenna comprises a chip, wherein a radiating piece for a bent slot is pasted on one surface of the chip. The structure of the bent slot antenna for an ultrahigh-frequency radio-frequency tag integrates the various characteristics of slot antennas, and the bent slot antenna can be easily matched in impedance with currently popular serial chips for ultrahigh-frequency radio-frequency tags, while the matching performance is better than that of a traditional ultrahigh-frequency tag antenna. Therefore, tag chips and antennas can be integrated conveniently in the future, which lays a foundation for the further cost reduction of ultrahigh-frequency radio-frequency recognition and the embedment of ultrahigh-frequency tags into the surface of an object. As long as the tag chip is directly connected to the input terminal of the antenna, an ultrahigh-frequency radio-frequency recognition tag can be obtained, while no other external devices are required. Therefore, the structure of the tag can be greatly simplified, the reliability of the tag is improved, and the tags and the antennas can be conveniently integrated in the future, so that the application cost of the radio-frequency recognition technology is greatly reduced.
Description
[technical field]
The utility model relates to a kind of electronic component, relates in particular to a kind of super high frequency radio frequency identification label in bending slit that is provided with bending slot antenna on radiation fin.
[background technology]
The application cost of super high frequency radio frequency recognition technology mainly is the cost of hyperfrequency label, and the label cost greatly depends on the cost of its antenna again.At present, the hyperfrequency label antenna is seen the antenna of electric tachometer indicator antenna and its distressed structure more, and these antenna and label chip impedance matching performance are not ideal enough, antenna size is big, and bandwidth is little, is not easy to integrated, cause the cost height of label, be unfavorable for the popularization and application of super high frequency radio frequency recognition technology.
[utility model content]
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of super high frequency radio frequency identification frequency range in 860-960MHz, be easy to impedance matching, and profile is low, volume is little, in light weight, processing is simple, easily with object is conformal and electrical property is diversified and the super high frequency radio frequency identification label in broadband with bending slot antenna.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of super high frequency radio frequency identification label comprises substrate with the bending slot antenna, is bonded with the radiation fin in bending slit on this substrate one side.
Described substrate has certain dielectric constant.
Described substrate thickness is greater than radiation fin thickness.
Described substrate four limit sizes equate with radiation fin four limit sizes.
Described substrate and radiation fin are shaped as rectangle.
Described radiation fin is a good conductor.
Described bending seam shape is a rectangle.
Described bending slit has certain width.
Center, described bending slit is a feeding centre.
The beneficial effects of the utility model are: super high frequency radio frequency identification label is with bending the slot antenna structure, the many characteristics that integrate slot antenna, carry out impedance matching with present popular hyperfrequency label with family chip easily, and matching performance is better than traditional hyperfrequency label antenna, be convenient in the future that label chip and antenna is integratedly, lay a good foundation for the further reduction application cost of super high frequency radio frequency identification and hyperfrequency label are embedded in body surface.As long as label chip directly is connected on the input of antenna, and need not other outward element, just can obtain super high frequency radio frequency identification label.So not only can greatly simplify label construction, improve the reliability of label, and be convenient in the future integrated with label chip and antenna, thereby reduce the application cost of REID widely.
[description of drawings]
Fig. 1 is the utility model structural representation;
Fig. 2 is the upward view of Fig. 1.
Among the figure: the 1-substrate, the 2-radiation fin, 3-bends the slit.
[embodiment]
Below in conjunction with drawings and Examples the utility model is further specified:
Referring to Fig. 1 and Fig. 2, a kind of super high frequency radio frequency identification label has substrate 1 with the bending slot antenna, is pasted with the radiation fin 2 in bending slit 3 on this substrate 1 one side, and wherein substrate 1 has certain dielectric constant, and substrate 1 is shaped as rectangle with radiation fin 2; Substrate 1 thickness is greater than radiation fin 2 thickness; Substrate 1 four limit sizes equate with radiation fin 2 four limit sizes.Wherein radiation fin 2 adopts good conductor, and the bending slit of offering in radiation fin 23 is shaped as rectangle, and has certain width.The center in bending slit 3 is a feeding centre.The label chip that matches with the bending slot antenna will directly be connected on the center position that bends slit 3.The operating frequency of antenna scope of this structure is in 860-960MHz, and the impedance of antenna can more easily obtain by changing its relevant parameter.Thus, the impedance matching of the hyperfrequency label chip that antenna is easy with at present popular, the matching performance index is better than the antenna performance index of dipole antenna and its distressed structure.Such label is placed in the read write line read-write scope compatible with it, utilize the reflection modulation principle, reading and writing device antenna sends electromagnetic wave energy and information, label antenna receives energy and the information that read write line is sent, make label chip according to instruction works, the information of impelling label antenna to respond is launched, and reading and writing device antenna receives this again and responds the information of coming.Like this, read write line and label just can exchange messages, thereby reach the purpose of radio-frequency (RF) identification.The utlity model has rational in infrastructure, make simple, be easy in the future with antenna and chip integrated, label is embedded in body surface and the low advantage of cost.
