Detailed description of the invention
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing, those skilled in the art is more clearly understood and how to put into practice the present invention.Describe the present invention although should be appreciated that in conjunction with its preferred specific embodiments, these embodiments are intended setting forth, instead of limit the scope of the invention.
As Fig. 1, shown in Fig. 2, it is a kind of packing jar with electronic tag shown in figure, specifically, refer to the residual oil in tank of packing jar, comprise a metal can 1, the upper surface of metal can 1 is provided with a ring-type indentation 8, metal can 1 upper surface posts an electronic tag 3, edge and the ring-type indentation 8 of electronic tag 3 are tangent, edge near points of tangency on electronic tag 3 is provided with a fixed connector 4, electronic tag 3 is provided with a conducting rod 7 away from the edge of points of tangency, electronic tag 3 is by fixed connector 4, conducting rod 7 is connected to metal can 1, electronic tag 3 is provided with a pulling eye 2 near conducting rod 7 place.User can pull pulling eye 2 to be opened by tank body 1 along this ring-type indentation, electronic tag 3 and fixed connector 5 is pulled down from metal can 1, and when user pulls pulling eye 2, conducting rod 7 is pulled off.Fixed connector 5 herein can be metal rivet, by electronic tag 3 together with the metal can partial fixing below electronic tag 3, conducting rod 7 is metallic rod body, the diameter of the part body of rod of conducting rod 7 is 0.1-5.0 millimeter, some body of rod of conducting rod 7 is very thin, and metal can 1 can be opened easily.
Electronic tag 3 comprises chip 5 and antenna, chip 5 is radio-frequency (RF) identification chip, described antenna is microstrip antenna, described antenna comprises the dielectric 61 and radiation body 62 that are close together from the inside to the outside successively, it is generally be surrounded by layer of metal layer (or tinsel) in the side of electronic tag that 62 dielectrics 61 are attached to metal can 1 upper surface, dielectric 61 and radiation body 62 is encased.Radiation body 62 comprises two radiation fins 621,622 separated from one another, a gap 9 is provided with between two radiation fins 621,622, be generally rectilinear slot, chip 5 is erected on gap 9 or is placed in gap 9, two radiation fins are electrically connected with chip 5 respectively, one radiation fin 621 is electrically connected by fixed connector 4 and metal can 1, and another radiation fin 622 is electrically connected by conducting rod 7 and metal can 1.
The total length L of two radiation fins 621,622 meets formula
, f is labeling task frequency 915MHZ, c is the light velocity, and h is label thickness, and W is radiation fin width,
it is the relative dielectric constant (because the shape of label is different, above length and width all refer to Length x Width effectively) of 61 dielectrics.Reduce fixed connector and can reach the object reducing antenna size, equal zero at the electric field of the position TM10 pattern of fixed connector.When fixed connector is narrower than radiation fin width, the effective inductance of antenna can increase and resonance frequency lower than traditional Shorted post loaded microstrip antenna, so reduce the width of fixed connector, can reduce antenna size further.
The label of prior art is the distortion in half-wave symmetry a period of time, and this label directional pattern and impedance when near metal will be had a strong impact on, and the reflex of tank body metal pair label seriously undermines original electromagnetic wave signal intensity in addition, causes label to read.In the present invention, load its Shorted post on label both sides, microstrip antenna label being become amount to a period of time or two terminal shortcircuits to load, greatly can promote the radiance of label like this, have outstanding antijamming capability.Destroy fixed connector when label is removed, cause the structure of this anti-metal to be broken, label cannot read near metal.Metal can 1, conducting rod 7 and fixed connector 4 form grounded antenna jointly, this grounded antenna and dielectric 61 are together with radiation body 62, form RFID antenna, enhance decipherment distance and the sensitivity of RFID antenna, effectively improve RFID antenna radiation effect.
When this metal can 1 is opened, user pulls pulling eye 2, and conducting rod 7 is pulled off, and grounded antenna is also just drawn bad.Conducting rod 7 is metal connector, and the diameter of the part body of rod of conducting rod 7 is 0.1-5.0 millimeter, and some body of rod of conducting rod 7 is very thin, is easy to be pulled off, metal can 1 can be opened easily.
Fixed connector 4 is vitals that antenna realizes anti-metal function and adjusts frequency, when chip distance fixed connector 4 is far away, then the impact of change on frequency of the width of fixed connector 4 is more responsive, experiment show that the bandwidth of general anti-metal tag is 30MHz, and the distortion of fixed connector 4 can change more than frequency 50MHz, and label cannot be worked, and in the process of the draw ring opened, fixed connector 4 can be pulled out of shape, and directly destroys the anti-metal structure of antenna, cannot work.Even if other parts are good, this entire physical also cannot complete its function, thus causes electronic tag can not be recycled again.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
