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 square circuit. Two branch antennas are disposed on a side of the signal circuit opposite to the chip. The two branch antennas respectively extend to two sides of the square circuit. Each branch antenna comprises a plurality of bending sections. Width of the last bending section is eight times of width of other bending sections. Length of the bending section is larger than a side length of the square circuit. The branch antennas derived by two pins are beneficial for clearness and stability of signals, the branch circuits on two sides are beneficial for increasing emission and reception of signals, and increasing reading distances of signals. Variation of dimension of the bending sections in the bending portion realizes transmission of special signals. The electronic tag is specifically suitable for EC chips, and is suitable for object management such as clothes and medicine.

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 utility model provides a kind of stable performance, is suitable for clothes, pharmaceutical product is 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 square loop, shown in a side derivative two Branching Antennas relative with chip on signal line, two Branching Antennas extend to the both sides in square loop respectively, each Branching Antenna forms by a plurality of bending segments, the width of last bending segment be all the other bending segment width doubly, the length of bending segment is greater than the length of side in square loop.

In described kink, the width of last bending segment is 8mm.

Described bending segment has four, and four bending segments are arranged in parallel and through curved bend broken line, connect successively.

The length of side in described square loop is 14-16mm.

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

Two derivative Branching Antennas of pin are beneficial to the steady and audible of signal, the branched line of both sides is beneficial to increases transmitting and receiving of signal, increase the distance that reads of signal, the variation of the bending segment size in kink realizes special signal transmission, and be specially adapted for EC chip, this label is suitable for the Item Managements such as clothes, medicine.

Accompanying drawing explanation:

Fig. 1 is the structural representation of the utility model intelligent electronic label;

Embodiment:

Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.

As shown in Figure 1, the utility model intelligent electronic label, it comprises substrate 1, be located at the signal line 2 on substrate 1, the chip 3 being connected with signal line 2, described chip 3 forms a square loop with signal line 2, shown in a side derivative two Branching Antennas 4 relative with chip 3 on signal line 2, two Branching Antennas extend to the both sides in square loop respectively, each Branching Antenna 4 forms by a plurality of bending segments 5, the width of last bending segment 5 is 8 times of all the other bending segment 5 width, the length of bending segment 5 is greater than the length of side in square loop, the length of bending segment 5 is preferably 30mm.

Wherein, in described kink, the width of last bending segment 5 is 8mm.

Described bending segment 5 has four, and four bending segments 5 are arranged in parallel and through curved bend broken line, connect successively.

Concrete, the length of side in described square loop is for there being multiple choices, such as: 14mm, 15mm or 16mm.
