To keep the purpose of the present invention, content and advantage clearer, with reference to the accompanying drawings and examples, to of the invention
Specific embodiment is described in further detail.
Fig. 1 is a kind of structural schematic diagram of RFID label antenna suitable for vehicle glass surface of the invention, such as Fig. 1 institute
Show, antenna includes: antenna body 1, ceramic bases 2 and chip 3.
As shown in Figure 1, antenna body 1 is arranged in ceramic bases 2.Antenna body 1 includes: first wedge-shaped part 11 and
Two wedge-shaped parts 12.First wedge-shaped part 11 and 12 opposite chip 3 of the second wedge-shaped part are symmetrical arranged.First wedge-shaped part 11 and second
Wedge-shaped part 12 becomes narrow gradually inwardly from outside.The hollow-out parts 12 around chip 3 are formed in the position of chip 3.Hollow-out parts
The end of the first wedge-shaped part 11 of side and the second wedge-shaped part 12 connects chip 3.
As shown in Figure 1, wherein hollow out 12 is at ellipticity.
As shown in Figure 1, first wedge-shaped part 11 and the second wedge-shaped part 12 become narrow gradually inwardly from outside, and close to core
It slightly broadens at piece 3, slightly broadens and be positioned around hollow-out parts 12.
As shown in Figure 1, antenna body 1 is thin slice made of having etching aluminum foil, and after process for pressing, aluminium foil appearance bread
Wrap up in PVC base and papery outer surface.Label has gum, can be pasted onto the case surface of non-metal shell.
As shown in Figure 1, the size of antenna body 1 is 75mm*15mm.The length and width of hollow out 12 depend on the output of matching chip
Resistance value.
The method that RFID label antenna suitable for vehicle glass surface of the invention designs, in each neck of RFID management
In domain, being managed article has the needs intensively put, when intensively putting, with the shortening of distance between label, the day of label
Line can interfere with each other, and common electronic tag performance will receive influence.
The present invention designs a kind of label antenna, and this tag antenna structure is special, and the small pieces metal by short distance interferes
When, performance decline is unobvious.The phase of label metal antenna can be effectively reduced after the distance between label is less in this characteristic
Mutually interference guarantees recognition effect when electronic tag is intensively put.The present invention is mainly applied to liquid article management
