An aspect of of the present present invention, a kind of radio-frequency (RF) tag is provided, this label comprises substrate, metal film and chip, it is characterized in that: described substrate is provided with inner groovy, described inner groovy surface is provided with metal film, and described chip is placed on substrate and is connected with the metal film on inner groovy surface or described chip directly is pasted on the metal film on inner groovy surface.
Another aspect of the present invention provides a kind of preparation method of radio-frequency (RF) tag, comprises the steps:
A) adopt the casting mode to produce upper surface in batches with each substrate of inner groovy, all be connected by the coupling part between each substrate;
B) adopt vacuum coating mode metal-plated membrane in the inner groovy of the upper surface of each substrate and each substrate;
C) metal film with each substrate top surface removes, and only stays the metal film on inner groovy surface as the antenna of label;
D) chip be arranged on respectively on each substrate and be connected with the metal film on inner groovy surface and realize and the antenna binding, perhaps chip being pasted respectively on the metal film on inner groovy surface;
E) cut off coupling part between each substrate, each radio-frequency (RF) tag that is prepared from is separated, namely complete the batch production of radio-frequency (RF) tag.
Beneficial effect of the present invention is:
1. label construction of the present invention and preparation method thereof is easily realized the batch production to label, and namely guaranteed performance, do not need again the techniques such as PCB production, milling cutter cutting and corrosion, namely simplified technological process, be convenient to large-scale mass production, reduced again cost, save time.
2. the present invention produces three-dimensional label substrate in batches in the mode of casting, avoids the later stage to cut into the technique of given shape with milling cutter.
3. label of the present invention adopts common plastics as label substrate, avoids using expensive pcb board material (being mainly epoxy resin), and does not need complicated PCB processing technology.

Embodiment
Below in conjunction with accompanying drawing, radio-frequency (RF) tag of the present invention and preparation method thereof is done further detailed description.
As shown in Figure 3, radio-frequency (RF) tag of the present invention comprises substrate 1, metal film 2 and chip 3.Adopt the casting mode to prepare the substrate 1 that upper surface has inner groovy 4 in this example, in the shape of substrate 1 and casting process in mould the shape of each substrate adapt, can be rectangle, trapezoidal, circular or other arbitrary shapes, this example describes as an example of isosceles trapezoid example.On substrate 1, the shape of inner groovy is decided according to the design of concrete label antenna, can have any shape., inner groovy 4 surfaces are provided with metal film 2, and chip 3 is placed on substrate 1 and is connected with the metal film 2 on inner groovy surface or described chip directly is pasted on the metal film on inner groovy surface.
As shown in Figure 2, the preparation method of radio-frequency (RF) tag of the present invention comprises the steps:
A) adopt the casting mode to produce upper surface in batches with each substrate 1 of inner groovy 4, between each substrate, 1 all is connected by coupling part 5; The concrete technology of casting mode is: adopt injection machine to be heated to melt liquid to insulating material, melt liquid is arrived airtight mould Inner with high-pressure injection, through cooling and shaping, eject upper surface after die sinking with each substrate 1 of inner groovy 4;
The insulating material of using in the casting mode in this example (for example adopts plastics, the materials such as PET, ABS, PMMA, HIPS) make substrate, can avoid like this using expensive pcb sheet material, and do not need metal etching process, not only reduced cost, the preparation method is also simpler, easily operation.the upper surface that the mold shape of using in this example and the present invention need make adapts with the substrate shape of inner groovy, for the step that simplifies the operation, be reserved with a connection channel between the model of need each substrate in mould, like this when injecting melt liquid in mould, interface channel also can be filled, be coupling part 5 recited above after die sinking, its material is also plastics, can realize easily that so just disposable injection melt liquid can mass-produce a plurality of substrates 1 in the mould, not only save time, increase work efficiency, each substrate of making also conveniently carries out subsequent operation.
