Embodiment
For the ease of understanding of the those skilled in the art to the art of this patent scheme, meanwhile, in order that the technology of this patent
Purpose, technical scheme and beneficial effect are clearer, and the protection domain of claims is fully supported, below with tool
The form of body case makes further, more detailed description to the technical scheme of this patent.
A kind of chipless radio frequency identification print label, it is formed by printing of conductive inks, including be sequentially connected be used for connect
Receive wide-band reception antenna unit, the spiral band elimination filter for making the signal of specific frequency decay of broadband signal
Group and the wide-band transmission antenna unit for launching broadband signal, the spiral band elimination filter group include multiple spirals
Bandstop filter.
Optionally, the wide-band reception antenna unit, multiple spiral band elimination filters and wide-band transmitting antenna list
It is the coplanar waveguide structure of cascade between member.
Optionally, the wide-band reception antenna unit and wide-band transmission antenna unit include coplanar wave guide feedback line
With disc aerial radiation structure, the periphery of the spiral band elimination filter group is additionally provided with co-planar waveguide ground structure.
Optionally, the wide-band reception antenna unit and wide-band transmission antenna unit are that two polarization modes are orthogonal
Wideband monopole sub-antenna.
Optionally, the resonant frequency of the spiral band elimination filter the wideband monopole sub-antenna coverage it
Interior, the length of the helical structure of multiple spiral band elimination filters is different, and each helical structure correspond to one it is different
Resonance frequency.
As shown in Figure 2-5, the chipless radio frequency identification print label is designed as 2 orthogonal wideband monopoles of polarization mode
The form of the band stop filter structure of sub-antenna and helical structure cascade, it includes vertical polarization monopole antenna 1, spiral band elimination
Wave filter group 11, horizontal polarization monopole antenna 10, coplanar waveguide feeder line 9 and co-planar waveguide 2；Wherein spiral band elimination filter
Group 11 is by the first helical structure 3, the second helical structure 4, triple-helix structure 5, the 4th helical structure 6, the and of the 5th helical structure 7
6th helical structure 8 forms.
In the example, the frequency of all channel antenna is 1.9~6GHz, antenna size：D is 15mm, L 25mm, H 8mm, W
It is for 10mm, W1 2mm, W2 1mm, W3 1mm, W50 3.77mm, h1 1mm, h2 1mm, h3 3.77mm, g
0.15mm；
The resonant frequency of 6 helical structures is 1.9~2.4GHz, size：Spiral spacing d is 2mm, and the height Hr of spiral is
3mm, L1 8.6mm, L2 8.4mm, L3 8.2mm, L4 8mm, L5 7.8mm, L6 7.6mm, s 0.6mm, wline

The principle of chipless radio frequency identification is carried out as shown in figure 1, Chip-free label reader first passes through using the label
Transmitting antenna sends broadband interrogation signal, and the reception antenna of Chip-free label receives the hurricane band through end cascade later after signal
Resistance filter construction is encoded to signal, and then the signal after coding is returned to by the transmitting antenna of Chip-free label and is read
The reception antenna of device is read, because the signal characteristic that different labels returns is different, so as to realize the identification to label.
The label can utilize the ink-jet printer after repacking directly to print conductive ink on a surface of an.The label
In multiple helical structures length it is different thus can have different resonant frequency points, each helical structure corresponds to a frequency
Point, according to decay of the helical structure to the signal of specific frequency, it is possible to achieve to the coding of label.Reader passes through detection signal
The presence or absence of amplitude judges that coding is 0 or 1, and so, the helical structure of N positions just has 2NKind coding, can represent 2NIt is individual different
Label.
Fig. 6 is the simulation result figure of three kinds of various forms of encoded signals, it is seen then that this label has good identification effect
Fruit.
