Description
Technical field
The utility model relates to field of radio frequency identification, is a kind of RFID tag specifically.
Background technology
RFID tag claims again electronic tag, transponder, data carrier; Reader is called again readout device, scanner, read head, communicator, read write line (depend on electronic tag whether can wireless rewrite data).Between electronic tag and reader, by coupling element, realize space (contactless) coupling 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 RFID tag of prior art generally comprises substrate, is located at the signal line (being antenna) on substrate, the chip being electrically connected to signal line, described 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, and the performance of signal receiving performance also needs to consider use occasion and the position of electronic tag certainly.The RFID tag of prior art is longer, mainly due to signal circuit, is provided with Branching Antenna, and the extension by Branching Antenna improves signal reception, will certainly lengthen so again the length of RFID tag.And in a lot of occasions, paste and use the position of label due to limited space, cannot paste lower RFID tag, for example, some small-sized precise parts, long and narrow label is attached on part and is easily wound around, thereby affects recognition effect.
Utility model content
The technical problems to be solved in the utility model is a kind of suitable length to be provided, and can to play the RFID tag of good recognition effect.
Technical solution of the present utility model is, a kind of RFID tag of following structure is provided, and comprises substrate, is located at the signal line on substrate, the chip being electrically connected to signal line, and described chip and signal line form a loop; Below loop, connect main antenna, the symmetrical extension toward both sides from main antenna, extend respectively left branch antenna and right branch antenna, left branch antenna and right branch antenna include a flat segments and two bending sections, described left branch antenna and right branch antenna all also comprise end antenna, described end antenna is connected to the end of bending section and extends upward, and upwardly extending length is 35-50mm.
Adopt above structure, the utility model compared with prior art has the following advantages: adopt the utility model, because left branch antenna and right branch antenna all also comprise end antenna, described end antenna is connected to the end of bending section and extends upward, upwardly extending length is arranged within the scope of certain numerical value, signal line is converted to from horizontal expansion extending longitudinally, thereby greatly reduce the length of product, also kept the signal reception that product is good simultaneously.
As improvement, described substrate is provided with two circular metal pasters, two described circular metal pasters respectively along chip be symmetricly set in chip directly over and under; Because prior art cannot be found rapidly the position that chip is installed, therefore as a reference point by two circular metal pasters are set, by finding the center between the two, the installation site that just can find chip to be connected with signal line.
As improvement, on described substrate, be also provided with cruciform metal patch, cruciform metal patch laterally consistent with the direction of flat segments, cruciform metal patch longitudinal consistent with the upwardly extending direction of end antenna; Due in whole forming label process, need to etch signal line, by the setting of cruciform metal patch, can guarantee etched linearity and verticality, thus further improving product performance.
As improvement, the end of the end antenna of left branch antenna and right branch antenna is inwardly laterally bending all; Described inwardly refers to toward chip direction, since so further extended antenna, has promoted signal reception, can not add again the length of long products.
As improvement, the length of the horizontal bending on end antenna is 5 ~ 15mm.In this vertical scope, signal reception is better.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model RFID tag.
As shown in the figure 1, substrate, 2, signal line, 3, chip, 4, main antenna, 5, left branch antenna, 6, right branch antenna, 7, flat segments, 8, bending section, 9, end antenna, 10, circular metal paster, 11, cruciform metal patch.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, RFID tag of the present utility model, comprises substrate 1, is located at the signal line 2 on substrate 1, the chip 3 being electrically connected to signal line 2, and described chip 3 forms a loop with signal line 2; Below loop, connect main antenna 4, the symmetrical extension toward both sides from main antenna 4, extend respectively left branch antenna 5 and right branch antenna 6, left branch antenna 5 and right branch antenna 6 include a flat segments 7 and two bending sections 8, described left branch antenna 5 and right branch antenna 6 all also comprise end antenna 9, described end antenna 9 is connected to the end of bending section 8 and extends upward, and upwardly extending length is 35-50mm.
Described substrate 1 is provided with two circular metal pasters 10, two described circular metal pasters 10 respectively along chip 3 be symmetricly set in chip 3 directly over and under; The thickness of described circular metal paster 10 is equal to or greater than the thickness of signal line 2.
