Abstract

The utility model provides an intelligent electronic tag, comprising a substrate, a signal circuit disposed on the substrate, and a chip connected with the signal circuit. The chip and the signal circuit form a rectangular circuit. The chip is disposed on a side of the rectangular circuit in an offset manner. Two sides of the chip respectively derive a left branch antenna and a right branch antenna. The right branch antenna comprises a first bending portion formed by a plurality of bending sections, and a second bending portion. The first bending portion is disposed below the rectangular circuit. The second bending portion is connected with the first bending portion and is on a side of the rectangular circuit. An upper end of the second bending portion is parallel with an upper end of the rectangular circuit, and a lower end is parallel with a lower end of the first bending portion. The left branch antenna comprises a left bending portion below the rectangular circuit and a straight section extending to the left. The left bending portion is formed by a plurality of bending sections. Conditions that the tag is cut are effectively prevented, and loss is greatly reduced.

Description

Intelligent electronic label

Technical field

The utility model relates to field of radio frequency identification, is a kind of intelligent electronic label specifically.

Background technology

Electronic tag claims again radio-frequency (RF) tag, transponder, data carrier; Reader is called again readout device, scanner, read head, communicator, read write line and depends on whether electronic tag can wireless rewrite data.Between electronic tag and reader, by coupling element, realize the contactless coupling in space of radiofrequency signal; In coupling channel, according to sequential relationship, realize transmission and the exchanges data of energy.Along with popularizing of Internet of Things, electronic tag is widely used the various occasions in people's life, for example, and the ETC of High-Speed Automatic charge; Automatic unlatching and the charge of parking lot railing; Special food source and the inquiry of sale whereabouts and tracking; Tracking on production line from semi-manufacture to finished product.In a word, electronic tag brings great convenience to people's production and daily life.The chip that the electronic tag of prior art generally comprises substrate, be located at signal line on substrate is antenna, be electrically connected to signal line, chip and signal line form a loop, and synchronous signal circuit has certain extension to strengthen the reception of signal.Below the usable range of also having mentioned electronic tag is very wide, and different occasions has different demands.The standard of considering electronic tag performance is mainly the false proof tracking performance of signal receiving performance and beared information etc., signal receiving performance shows the stability of signal reception and the distance that signal receives, certainly the performance of signal receiving performance also needs to consider use occasion and the position of electronic tag, in actual use, adjust the antenna of label and the stability of chip guarantee signal according to different use occasions.

Utility model content:

For solving above-mentioned technical matters, the intelligent electronic label that the products such as the utility model provides a kind of stable performance, is suitable for jewelry, jewellery are used.

The technical solution of the utility model is, a kind of intelligent electronic label with following structure is provided, it comprises substrate, be located at the signal line on substrate, the chip being connected with signal line, described chip and signal line form a rectangle loop, described chip biasing is positioned at a side in rectangle loop, the both sides of described chip are two Branching Antennas in derivative left and right respectively, right branch antenna comprises the first kink and the second kink being comprised of a plurality of bending segments, the first bending part is in the below in rectangle loop, the second kink is connected and is positioned at a side in rectangle loop with the first kink, the upper end of the second kink is parallel with the upper end in rectangle loop, lower end is parallel with the lower end of the first kink, left branch antenna comprises the flat segments that is positioned at the left kink of below, rectangle loop and the extension of turning left, left kink is comprised of a plurality of bending segments.

In the second described kink, the width of last bending segment is three times.

The width of described flat segments is the twice of bending segment in left kink.

The length of described flat segments is 40mm, and width is 1mm.

Adopt after said structure, the utlity model has following advantage:

The branched line of both sides is beneficial to increases transmitting and receiving of signal, increase the distance that reads of signal, special Branching Antenna structure realizes special signal transmitting, be beneficial to distinguishing of signal, the performance of performance in like product is more outstanding, the compound tense cross cutting of being more convenient for, the side-play amount while having reduced cross cutting, effectively prevented from switching to the situation of label, the loss reducing greatly.And be beneficial to and increase the tagged distance that reads, be suitable on logistics, storehouse management and article checking.
