Village's label can receive the signal that the read write line goes out, and first be believed the UHF received by coupling part 31 thereon by the second antenna 3
Number by coupling make first antenna 11 receive UHF read determine signal, corresponding signal can be transmitted to chip, realizes reading electronic labels
Information.
Due to not being by being rigidly connected between the second antenna 1 and first antenna, and couple and form signal circuit, both can be with
Avoid damaging chip during washing or chip comes off, easily welded when label chip can be avoided directly to be connected with an antenna again
Point loosens, and influences to use.In theory, rigid antenna base material can accomplish with label chip sizableness, will not be right during washing
Washing facility or the article used produce any influence, can be widely applied to clothing washing, hotel needs to clean and reused
Bedding, Item Management is easy in and the article that uses of the more repeated washing of the quantity such as hospital or place.
For in theory, the gap between the first antenna 11 and coupling part 31 is extra small, and frequency skew during coupling is extra small,
The coupling part couples longer with first antenna, and frequency skew during coupling is extra small.But in actual fabrication UHF electronic tags,
It can not accomplish to fix by design attitude completely between first antenna and coupling part, thus there is also certain error, the first antenna
Deviation between coupling part is in ± 1mm, interior controllable coupling frequency skew.
In order to solve the required precision existing for above-mentioned implementation between first antenna 11 and coupling part 31.The present invention also proposes
Another embodiment.
As shown in Figure 3-4, fixing groove 13 is provided with the rigid antenna base material 1, the both sides of the fixing groove 13 extend to
The side of rigid antenna base material 1, the fixing groove 13 are located at the outside of first antenna 11, and its shape is identical with first antenna 11.Solid
When determining the making of groove 13, degree of precision can be accomplished, make the distance between fixing groove 13 and first antenna 11 identical, when fixing groove 13
When section is suitable with the diameter of the second antenna 3 of flexibility, will be placed in the second antenna 3 in fixing groove 13 it is fixed after, positioned at
The second antenna of part 3 in fixing groove 13 forms coupling part 31, and the coupling part 31 is also inevitable identical with the distance of first antenna 11,
Avoid the second antenna 3 being fixed on base material 2 under flexibility, and when first antenna 11 is located at rigid antenna base material 1, to production technology compared with
High-precision requirement, the other structures of electronic tag are same as the previously described embodiments.
Contact friction during in order to avoid rubbing soft with the hands between the end of fixing groove 13 and the second antenna 3, by the fixing groove 13
End set to be horn-like, make between the second antenna 3 and two ends of fixing groove 13 in larger clearance position.
As seen in figs. 5-6, can also be as needed, the fixing groove 13 is arranged on side and the position of rigid antenna base material 1
In the outside of first antenna, its shape is identical with first antenna 11, and 13 two ends of fixing groove now can also be set with consolidating
Determine the consistent clearance position of the vertical direction of groove 13, the clearance position both ends extend respectively into the upper and lower surface of rigid antenna base material 1.
As shown in fig. 7, the present invention also provide it is a kind of it is above-mentioned apply a preparation method for UHF electronic tags, the UHF electronic tags
Preparation method include,
S10 steps, tag circuit body making step, printed circuit board (PCB) are taken as rigid antenna base material 1, in rigid antenna
Being set on base material 1 needs the first antenna 11 and label chip 12 of shape, first antenna 11 is formed signal with label chip 12
Connection, form tag body.
S11 steps, label carrier making step, appropriately sized flexible sheet material is taken to be used as flexible upper base material 4 and soft
Property under base material 2, the fixed labels circuit main body on base material 4 under base material 2 or flexibility in flexibility, then fixation has coupling part 31 and two
Second antenna 3 of individual extension 30, make coupling part 31 identical with the shape of first antenna 11 in tag circuit main body, and spacing is equal
It is even, electric pathway can be formed with first antenna under UHF signals, form label carrier.Specifically, the flexible upper He of base material 4
The lower material of base material 2 of flexibility is selected as needed, can use waterproof material.
S12 steps, flexible parent metal composite steps, in the label carrier for being fixed with the second antenna 3 and tag circuit main body
Another flexible parent metal is covered, makes two compound fixations of flexible parent metal, forms UHF electronic tags.Specifically, when the second antenna 3
When being fixed on base material 2 under flexibility with tag circuit main body, then base material in flexibility 4 is covered into the separately base material 2 under flexibility in this step
On, make the antenna 3 of rigid antenna base material 1 and second between flexible lower base material 2 and flexible upper base material 4, then pass through existing process
Gluing or the mode such as thermosol make both adhere fixation, and vice versa, repeats no more.Second antenna 3 can certainly be fixed on
The lower base material 2 of flexibility, tag circuit main body are fixed on base material 4 in flexibility, then two base materials progress are compound, are controlling precision
Situation can also realize, its shortcoming is that the position accuracy demand of compound tense is high, it is impossible to offset, otherwise first antenna and the
It can not couple to form electric pathway between two antennas.
When using compound tense is heated, being provided with hot melt adhesive layers between base material 2 under base material 4 and flexibility in flexibility, pass through heat
