Description
Technical field
The utility model relates to field of data recognition, particularly relates to a kind of passive electronic label.
Background technology
REID is a kind of non-contact automatic identification technology realized based on radio frequency recognition principle.It is with radiofrequency signal and Space Coupling, transport property, drives electronic tag circuit to send the coding of its storage.RFID antenna is the key components determining radio-frequency recognition system performance, the electromagnetic intensity of antenna transmission and directivity, determine operating distance and the induction of electronic tag, the electrical quantitys such as the impedance of antenna and bandwidth, can affect the matching degree of collector and antenna.The design of antenna needs the factor such as size, watt level considering antenna.The transmitting and receiving of aerial signal, its performance directly determines the success or not of radio communication.
In order to adapt to the normal condition of Internet of Things, it is enough little that the trend of the design of label antenna will meet size, can be attached on the article of needs; Directivity wants omnidirectional or hemisphere to cover, and does not limit the placement of label; Maximum signal energy can be provided to the chip of label.
In existing technology, REID is guarantee accuracy and the reliability of antenna, and its Antenna Design normally arranges two doublet antennas, and has limitation on size shape, cannot meet difform product.In order to maximum signal energy can be provided to the chip of label, its design is comparatively complicated.But REID adopts conductive material compared to the common bar code adopting ink, and himself cost is higher, adds complicated profile design, adds the cost of antenna.Market lacks a kind of shape freely, reliability is high, lower-cost passive electronic label.
Utility model content
Goal of the invention of the present utility model is the limitation solving above-mentioned existing passive electronic tag, and provide a kind of shape freely, reliability is high, lower-cost passive electronic label.
A kind of passive electronic label of the utility model, comprises substrate, chip that the short-circuited conducting sleeve antenna be positioned on substrate is connected with the feeding point on the downside of short-circuited conducting sleeve antenna; Described short-circuited conducting sleeve antenna central upper is provided with an outside joint; Described connector end is spread out respectively to both sides and is stretched out the symmetrical Branching Antenna of two mirrors, described Branching Antenna is strip and encloses the rectangle frame do not closed, described short-circuited conducting sleeve antenna is located in rectangle frame, described Branching Antenna end is respectively equipped with broadside, and described Branching Antenna is provided with the arcuate structure to rectangle frame indent.
After adopting above structure, the utility model compared with prior art, has the following advantages:
A kind of passive electronic label of the utility model adopts the Branching Antenna of strip to be strip and encloses the rectangle frame do not closed, and single strip structure is simply clean and tidy, saves material and cost; Rectangle frame structure of the present utility model, is different from common strip doublet antenna, the length of described rectangle frame and widely can to arrange in any proportion, to adapt to difform product; Described short-circuited conducting sleeve antenna is placed in described rectangle frame, takes full advantage of the space of passive electronic label, the size of passive electronic label can be accomplished minimum; Described rectangle frame is provided with the arcuate structure of indent, and concave inward structure does not take redundant space, and arcuate structure makes impedance variation mild as transition structure, and adds the length of Branching Antenna, is conducive to reception and the transmitting of signal.In guarantee antenna passive electronic label shape described in the utility model freely, reliability is high, and cost is lower for the utility model.
As preferably, described arcuate structure is located at the left and right sides of described rectangle frame.Rationally distributed, make full use of space, reduce the size of passive electronic label.
As preferably, described short-circuited conducting sleeve antenna and Branching Antenna material can be copper or aluminium or silver slurry and electrically conductive ink.
As preferably, the material of described substrate can be fragile paper or polyvinylchloride or resin glue ABS or poly-to phenyl formic acid glycol ester PET or polyimide PI.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Shown in figure 1, substrate, 2, short-circuited conducting sleeve antenna, 3, chip, 4, Branching Antenna, 5, rectangle frame.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The chip 3 that passive electronic label as a kind of in Fig. 1 comprises substrate 1, the short-circuited conducting sleeve antenna 2 be positioned on substrate 1 is connected with the feeding point on the downside of short-circuited conducting sleeve antenna 2; Described short-circuited conducting sleeve antenna 2 central upper is provided with an outside joint; It is characterized in that: described connector end is spread out respectively to both sides and stretched out the symmetrical Branching Antenna 4 of two mirrors, described Branching Antenna 4 is strip and encloses the rectangle frame 5 do not closed, described short-circuited conducting sleeve antenna 2 to be located in rectangle frame 5, described Branching Antenna 4 end is respectively equipped with broadside, and described Branching Antenna 4 is provided with the arcuate structure to rectangle frame 5 indent.Described arcuate structure is located at the left and right sides of described rectangle frame 5.Described short-circuited conducting sleeve antenna 2 and Branching Antenna 4 material can be copper or aluminium or silver slurry and electrically conductive ink.The material of described substrate 1 can be fragile paper or polyvinylchloride or resin glue ABS or gather phenyl formic acid glycol ester PET or polyimide PI.
In addition, both sides described in the utility model Branching Antenna 4 can be that respectively to have an indent arcuate structure also can be multiple indent arcuate structures varied in size; Meanwhile, also can paste the shape of the product of passive electronic label as required, change size and the length breadth ratio of the rectangle frame 5 of passive electronic label described in the utility model.
It is that example is illustrated that the utility model both sides Branching Antenna 4 respectively has an indent arcuate structure, but is not limited only to above-mentioned this form.
