Abstract
The utility model relates to a fan-shaped bow tie antenna for ultra-high-frequency electronic tags. The fan-shaped bow tie antenna comprises a dielectric substrate. Symmetrical upper and lower fan-shaped bow tie radiation elements and stubs connected with the radiation elements are applied on the dielectric substrate. The center of symmetry of the two fan-shaped bow tie radiation elements and the stubs is the feeding center. An ultra-high-frequency radio frequency identification tag can be obtained only by directly connecting a tag chip to the feeding input end of the antenna without the need for additional external components. The tag structure can be greatly simplified, and the reliability of tags can be improved.
Description
Technical field
The utility model relates to a kind of electronic component, relates in particular to a kind of radiation fin and be shaped as the super high frequency radio frequency identification label antenna of fan-shaped knot.
Background technology
The application cost of super high frequency radio frequency recognition technology is mainly the cost of its label, and label cost greatly depends on again the cost of label internal antenna.At present, the bending element antenna of the common electric tachometer indicator antenna of ultrahigh-frequency tag antenna and its distressed structure.These antenna and label are undesirable with chip impedance matching performance, and antenna size is large, and bandwidth is little, causes the cost of label high, is 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 mate with RFID tag chip, and profile is low, volume is little, lightweight, be convenient to the fan-shaped Bow―tie antenna of super high frequency radio frequency identification label integrated and electrical property variation and broadband.
The utility model solves the technical scheme that its technical problem adopts: the fan-shaped Bow―tie antenna of a kind of super high frequency radio frequency identification label, comprise dielectric substrate, the fan-shaped knot radiation element of the upper and lower two groups of symmetries of applying ointment or plaster on this dielectric substrate and the detail that is connected with radiation element, two groups of fan-shaped knot radiation elements and with the symmetrical centre of detail be feeding centre.
Described substrate has certain dielectric constant, and is rectangle.
Described substrate thickness is greater than radiation element thickness.
Described substrate four limit sizes are greater than radiation element and detail size.
Described radiation element and detail are good conductor.
Described radiation element is shaped as fan-shaped.
The detail of described connection radiation element is shaped as rectangle.
Described two groups of fan-shaped knot radiation elements and detail are for symmetrical in opposite directions.
The beneficial effects of the utility model are: fan-shaped Bow―tie antenna structure for super high frequency radio frequency identification label, integrate the various features of microstrip antenna, easily carry out impedance matching with at present popular ultrahigh-frequency tag with family chip, matching performance is better than traditional ultrahigh-frequency tag antenna, and antenna miniaturization is with the obvious advantage, be convenient in the future integrated to label chip and antenna, lay a good foundation for the further reduction application cost of super high frequency radio frequency identification and ultrahigh-frequency tag are embedded in body surface.As long as label chip is directly connected on the feed input of antenna, and without other outward element, just can obtain super high frequency radio frequency identification label.Can greatly simplify like this label construction, improve the reliability of label.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the face of the looking up figure of Fig. 1.
In figure: 1-substrate, 2-radiation element, 3-detail.
Embodiment
Below in conjunction with accompanying drawing and enforcement, the utility model is further illustrated.
Referring to Fig. 1 and Fig. 2, the fan-shaped Bow―tie antenna of a kind of super high frequency radio frequency identification label, by the Rectangular Enclosure with Participating Media substrate 1 with certain dielectric constant, on face of substrate, be laid with the fan-shaped knot radiation element 2 of conductor of two groups of symmetries and the rectangle detail 3 of bonding conductor radiation element, two groups of radiation elements 2 are feeding centre with the symmetrical centre of detail 3, substrate 1 thickness is greater than radiation element 2 and detail 3 sizes, substrate 1 four limit sizes are greater than the size of radiation element 2 and detail 3, radiation element 2 and detail 3 adopt good conductor, the label chip matching with fan-shaped Bow―tie antenna will be connected on this symmetrical centre position.
The operating frequency of antenna scope of this structure is in 860-960MHz, the impedance of antenna can obtain by changing its relevant parameter relatively easily, thus, antenna is easy to mate with at present popular ultrahigh-frequency tag chip, matching performance index is better than the antenna performance index of conventional dipole sub antenna and its distressed structure, the label made from this antenna is placed within the scope of the read write line read-write compatible with it, utilize reflection modulation principle, reading and writing device antenna sends electromagnetic wave energy and information, label internal antenna receives energy and the information that read write line is sent, make label chip according to instruction works, the information transmitting that impels label antenna to respond is gone out, 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 object of radio-frequency (RF) identification, have rational in infrastructure, manufacture simple, be easy in the future integrated by antenna and chip, label is embedded in to body surface and the low advantage of cost.
