Description
Technical field
The utility model belongs to field of radio frequency identification, more particularly, relates to a kind of anti-metal electronic tag.
Background technology
Along with the fermentation of Internet of Things concept, REID is more and more paid attention to.Countries in the world and each large organizing have all been formulated relevant art standard according to s own situation, and the band limits that different standards relates to is also not quite similar.Only just there are 840MHz-845MHz and two frequency ranges of 920MHz-925MHz in China.And as the anti-metal electronic tag of REID important component part, it is the identification of the object of metal for surface, for example, container, flame snuffer.Anti-metal electronic tag has been used widely and has been also had larger application prospect at present.But anti-metal tag bandwidth is narrower under normal circumstances, can only be used for single frequency range, there is larger application limitation.
Utility model content
The technical problems to be solved in the utility model is, for the single shortcoming of prior art anti-metal electronic tag service band, provides a kind of two-band anti-metal electronic tag that can use under two kinds of different frequency bands.
The utility model solves the technical scheme that its technical matters adopts: construct a kind of two-band anti-metal electronic tag, formed by radiation matrix 1 and frequency adjustment pad 2, wherein said radiation matrix Shang Xia 1 both sides be label antenna 4, on described label antenna 4, label chip 3 is installed, described frequency adjustment pad 2 is arranged on the side that described label chip 3 is installed on described radiation matrix 1.
Further, described radiation matrix 1 is made up of insulating material.
Further described label antenna 4 comprises the Copper Foil being arranged on described radiation matrix 1 upper and lower surfaces and the short circuit hole 5 that is connected described radiation matrix both sides Shang Xia 1.
Further, described frequency adjustment pad 2 is made up of insulating material, and its two sides does not all arrange Copper Foil.
Further, described radiation matrix 1 two sides is electrically connected by short circuit hole 5 as the Copper Foil two ends of label antenna 4.
Further, described label chip 3 installation sites can regulate according to the difference of label tuning-points apart from the distance in short circuit hole 5.
Further, described radiation substrate 1 and described frequency adjustment pad 2 combine by pressing or bonding mode.
Implement a kind of anti-metal electronic tag of the present utility model, there is following beneficial effect: when the one side that has frequency adjustment pad on described two-band anti-metal electronic tag is affixed on to metal surface, due to the effect of described frequency adjustment pad, described label antenna is equivalent to an electric small loop antenna perpendicular to metal surface that electrical length is larger, and now electronic tag presents compared with low resonant frequency; Described two-band electronic tag is affixed on to metal surface without the one side of frequency adjustment pad, and described label antenna is equivalent to one perpendicular to the less electric small loop antenna of the electrical length of metal surface, and now electronic tag presents upper resonance frequency.So, anti-metal electronic tag just can meet the frequency needs of two kinds of various criterions.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of two-band anti-metal electronic tag of the present utility model;
Fig. 2 is the inner structure schematic diagram of a kind of two-band anti-metal electronic tag of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further.
As shown in Figure 1 and Figure 2, in a kind of two-band anti-metal electronic tag of the utility model embodiment, this electronic tag comprises radiation matrix 1 and frequency adjustment pad 2, wherein radiation matrix Shang Xia 1 both sides be label antenna 4, label antenna 4 comprises and covers the radiation patch of radiation matrix 1 upper and lower surface and be arranged on the label chip 3 in arbitrary radiation patch wherein, and frequency adjustment pad 2 is positioned at the side that label chip 3 is installed on radiation matrix 1.In the two ends of radiation matrix 1, radiation patch, offer the short circuit hole 5 that makes to be positioned at the radiation patch electrical connection on radiation matrix 1 upper and lower surface through radiation matrix 1.Short circuit hole 5 is for covering copper vias.
In the present embodiment, radiation matrix 1 and frequency adjustment pad 2 form one by pressing or bonding mode.
In the present embodiment, above-mentioned radiation matrix 1 and frequency adjustment pad 2 are all made up of insulating material, for example FR4, and wherein the upper and lower surface of radiation matrix 1 is label antenna 4.
In the time that electronic tag has frequency adjustment pad 2 one sides to be affixed on metal object surface, electronic tag presents relatively low frequency, in the time that electronic tag is affixed on metal object surface without frequency adjustment pad 2 one sides, presents relatively high-frequency characteristic.Can regulate tuning-points by the position that regulates label chip 3 distance short circuit hole on label antenna.
Outside dimension of the present utility model is 50mm × 5mm × 3mm.This electronic tag is mainly made up of two parts: the radiation matrix and the frequency adjustment pad that is of a size of 50mm × 5mm × 1.5mm that are of a size of 50mm × 5mm × 1.5mm.Label antenna is coated with the radiation patch of 49mm × 4mm × 0.035mm away from the radiating surface of frequency adjustment pad one side.Radiation patch adopts Copper Foil to make.In the radiation patch that label antenna is 49mm × 4mm × 0.035mm near the radiating surface of frequency adjustment pad one side, reserved chip is installed the Copper Foil in gap, and label chip nation is fixed or be welded in this reserving gaps place.This clearance distance radiation patch wherein distance on one side is 25mm.Have apart from 2mm place of radiation patch edges at two ends place the short circuit hole that a diameter is 2mm, two radiation patch up and down of label antenna are electrically connected by these two short circuit holes.While a side that has frequency adjustment pad being affixed on to metal object surface when use, electronic tag center resonant frequency is 840MHz, and when a side that is provided with frequency adjustment pad is affixed on to metal object surface, electronic tag center resonant frequency is 922MHz.These two frequency ranges are just desired two frequency ranges of Chinese national standard.
