Abstract
The invention relates to an antenna of an ultrahigh frequency radio frequency transponder, in particular to a transponder antenna for UHFRFID electronic tag, which belongs to the technical field of ultrahigh frequency radio frequency transponders. In the invention, a conductor pattern extending on both sides of a metal contact point that adheres the pins of an integrated circuit IC is designed symmetrically, i.e. the conductor pattern is long on one side while short on the other; therefore, the antenna is beneficial to be bent and adhered with 180 degrees at the bottle neck and is used together with a H3 chip of the Higges to get good reading capability; and the antennae at two sides prevent the mutual counteraction caused by oscillation. Experiment results show that the reading distance is quite far and longer than 3.8 m, and the antenna can be encoded freely, encrypted and destroyed invisibly and has uniqueness. The invention is suitable for being stuck at a bottle neck, or on an object having a bent surface, or an object the surface of which enables the two sides of a traditional symmetrical antenna to counteract with each other resulting from the oscillation; and the invention is applicable for marking, anti-counterfeiting and logistics management.
Description
Technical field
The present invention relates to a kind of antenna of ultrahigh frequency radio frequency transponder, relate in particular to the employed a kind of transponder antenna of UHFRFID electronic tag, belong to the ultrahigh frequency radio frequency transponder technical field.
Background technology
Along with science and technology development, field that electronic tag is used and occasion are more and more, but different fields also has different requirements with occasion to the transponder structure in the electronic tag, and for example the bottle of the bottle of filling liquid series products and Related product all wishes to have corresponding electronic label to be pasted on the bottleneck position in sign, false proof and logistics management.The antenna pattern design of transponder is generally symmetric form in the existing general UHF RFID electronic tag, promptly is the center with IC, designs a little ring, serves as that the basis radiate to bilateral symmetry with little ring.General universal ultrahigh frequency electronic tag reads distance at 4-6 rice, it is the longest also to read distance, after sticking on the bottle, reading distance can drop within 1.5 meters, on practicality, have a greatly reduced quality, trace it to its cause Shi Yin Wei Stickers to bottle on after, the antenna of chip Two Side symmetrical expression has produced concussion for receiving the electric wave that reader sends, because after the label doubling, if because of direction cancel each other cause. but for avoiding shaking cancelling each other of causing, and whole label is attached to bottle list Side, again can because of the antenna lower end can the liquid level in bottle under, and moisture is to absorb electric wave, causes received-signal strength to reduce, make that reading distance descends, therefore also infeasible.
Summary of the invention
The antenna that the purpose of this invention is to provide a kind of ultrahigh frequency radio frequency transponder, the antenna that overcomes transponder in the existing electronic tag is not suitable for being pasted on bottle, especially is not suitable for being pasted on the deficiency at bottleneck position, by the present invention, the realization working frequency range is 860-960MHz, be fit to be pasted on the bottleneck position, improve and read distance, help sign, false proof and logistics management.
The objective of the invention is to be achieved through the following technical solutions, a kind of antenna of ultrahigh frequency radio frequency transponder, the metallic contact that comprises bonding integrated circuit (IC) pin, metallic contact top alignment mark at interval, it is characterized in that, the metallic contact both sides are extended the conductor that constitutes antenna and are asymmetric long figure, and promptly a side is long, a side is short.
The both sides of the short side conductor of metallic contact are provided with the bending mark.
Described bending is labeled as half round cut.
The conductor fig that the present invention extends the metallic contact both sides of bonding integrated circuit (IC) pin is asymmetrical design, promptly a side is long, one side is short, help pasting in the 180 degree bendings at bottleneck position, cooperate the H3 chip of Higges to use, splendid reading performance is arranged, the both sides antenna is avoided because of cancelling each other that concussion produces, experiment shows that the present invention reads apart from far away relatively, can reach more than 3.8 meters, have and to encode arbitrarily, has uniqueness, can encrypt, can invisiblely disappear and function such as ruin, the present invention is fit to be pasted on the bottleneck position, the object that perhaps has flexure plane, perhaps wall-attached surface can make the object of cancelling each other because of concussion produces in traditional symmetrical expression antenna both sides, is suitable for sign, false proof and logistics management.
Description of drawings
Fig. 1 is an embodiment of the present invention structural representation.
Embodiment
Further specify the present invention in conjunction with the accompanying drawings and embodiments, the present invention is by the metallic contact 3 of bonding integrated circuit (IC) pin, metallic contact 3 tops alignment mark 4 at interval, and metallic contact 3 anisopleual long conductor 1 figures that constitute antennas that extend constitute.
Figure 1 shows that the version of an embodiment of the present invention, be separated with alignment mark 4 between metallic contact 3 tops of present embodiment, the figure of 3 liang of side conductor 1 asymmetric length of metallic contact is a rectangle, has axial groove 2 on the rectangular conductor 1 under the metallic contact 3.Rectangular conductor 1 length overall is 83.5～84.5mm, width is 2.9～3.1mm, axial groove 2 length on the conductor 1 are 23～24mm, width is 0.9～1.1mm, the both sides of metallic contact 3 short side conductor 1 corresponding axial groove 2 ends are provided with bending mark 5, bending mark 5 is a half round cut, and the short side end edge of half round cut centre-to-centre spacing is 23.5～24.5mm.
The conductor 1 that extend metallic contact 3 both sides among the present invention can be other figure, and the size of asymmetric figure is not restricted to the described embodiments.
