The radio frequency tag 2 sequentially comprises a base material 21, an impedance matching network 22, a chip 23 and an adhesive layer 24; the impedance matching network 22 is coupled to the antenna 3, which may also be referred to as an antenna radiator. The base material of the radio frequency tag includes a PET (Poly Ethylene Terephthalate) film, a plastic film or a resin film, that is, the material of the base material 21 may be a PET material, or may be other plastic or resin materials, such as a polyimide film, and the dielectric loss tangent value of the base material is small. The impedance matching network 22 may be formed by etching a conductive material, or by laser engraving a conductive material, for example, the impedance matching network 22 is formed by etching or laser engraving a conductive material such as aluminum, copper, etc. The chip 23 is a radio frequency chip, and is bonded to the impedance matching network 22 through a flip-chip (flip-chip) process. The thickness of the radio frequency tag 2 is set between 0.06mm-0.15mm, such as 0.06mm, 0.07mm, 0.08mm, 0.09mm, 0.1mm, 0.11mm, 0.12mm, 0.13mm, 0.14mm or 0.15 mm.
Referring to fig. 4, a schematic diagram of an example of an impedance matching network of a radio frequency tag according to an embodiment of the present application is shown.
The impedance matching network 22 as shown comprises: a first inductive microstrip circuit 226, a second inductive microstrip circuit 227, a first feed microstrip line 225 and a second feed microstrip line 228; the first inductive microstrip circuit 226 and the second inductive microstrip circuit 227 are connected in parallel, the first feeding microstrip line 225 is conducted with the first inductive microstrip circuit 226 and the second inductive microstrip circuit 227, and the second feeding microstrip line 228 is conducted with the first inductive microstrip circuit 226 and the second inductive microstrip circuit 227. The first feed microstrip line 225 and the second feed microstrip line 228 feed the antenna 3 in a coupled manner.
The first inductive microstrip circuit 226 is composed of a second microstrip line 222, a third microstrip line 223 and a fourth microstrip line 224; the second inductive microstrip circuit 227 consists of a second microstrip line 222, a third microstrip line 223 and a first microstrip line 221; the first feeding microstrip line 225 is conducted with the second microstrip line 222, and the second feeding microstrip line 228 is conducted with the third microstrip line 223.
Optionally, the second microstrip line 222 and the third microstrip line 223 are meander microstrip lines, and the first inductive microstrip circuit 226 and the second inductive microstrip circuit 227 can obtain higher equivalent inductance with a smaller physical size by means of meander. The impedance matching network 22 can be made to conjugate match a Radio Frequency (RFID) chip that is capacitive with a small physical size. The impedance matching network 22 is formed by connecting two inductive microstrip circuits (226, 227) in parallel, and compared with the inductive impedance matching network formed by a conventional L-shaped impedance matching network, the impedance of the inductive impedance matching network is relatively less affected by the surface metallization pattern of the package and the internal objects when the inductive impedance matching network is partially shielded.
In the embodiment of the application, the box is formed by pasting after the cardboard is folded, and radio frequency tag 2 and antenna 3 are attached 1 inboard of box. Two feed microstrip lines (225, 228) of the radio frequency tag 2 are located right above the antenna 3 and perform coupling feed on the antenna radiator, and the radio frequency tag 2 and the antenna 3 can be located at various positions inside the box body 1 and can be selected based on actual requirements.
In the embodiment of the present application, the antenna 3 is a metal film, an electrochemical aluminum foil, or a conductive ink layer. The antenna 3 may be made of a conductive material. The antenna 3 may be a metal film formed by die cutting, an electrochemical aluminum foil obtained by stamping, or a conductive ink layer formed by printing, for example.
In an alternative embodiment, as shown in fig. 1 and 2, the antenna 3 is in the form of a strip, and the antenna 3 is die-cut from a metal film to form a metal strip, and then is adhered to the inner surface of the cardboard packaging material by an adhesive. The antenna 3 is composed of three radiators which are conducted with each other, and includes: a first radiator 31, a second radiator 32, and a third radiator 33 that are conductive to each other. After the box body is bonded, the first radiator 31, the second radiator 32 and the third radiator 33 are respectively arranged on three sequentially adjacent surfaces of the box body 1 to form an omnidirectional antenna with a C-shaped structure, and meanwhile, the first radiator 31, the second radiator 32 and the third radiator 33 are respectively in three different directions relative to a logistics object inside the package, so that the influence of articles inside the radio-frequency packaging box is small, and even if liquid and metal are borne in the radio-frequency packaging box, the radio-frequency packaging box disclosed by the embodiment of the application can also read the RFID tags from multiple directions to obtain good radio-frequency performance.
As shown in the example of fig. 2, the first radiator 31 is adhered to the upper opening insert 11, the second radiator 32 is adhered to the top plate 12, and the third radiator 22 is adhered to the rear end plate 14. After the box body is bonded, the first radiator 31, the second radiator 32 and the third radiator 33 are respectively arranged on the top surface of the box body 1 and three surfaces of two opposite side surfaces of the box body, so as to form an omnidirectional antenna with a C-shaped structure. For another example, the first radiator 31 is adhered to the lower opening insert 19, the second radiator 32 is adhered to the bottom plate 18, and the third radiator 22 is adhered to the front end plate 15, which may be set according to requirements.
In another alternative embodiment, as shown in fig. 5 and 6, the antenna 3 and the rf tag 2 are disposed on the upper adhesive plate 13. Wherein, the surface of the paperboard can form a metallized pattern by using an electrochemical aluminum stamping process. When the metallized pattern is hot stamped by using the processes of hot stamping of the alumite and the like, the antenna 3 can be synchronously processed by using the metallization processes of hot stamping of the alumite and the like at the position of the upper rubber plate 13. After the antenna 3 is processed, the radio frequency tag 2 is labeled at the position shown in fig. 5, and the coupling feeding of the radio frequency tag 2 to the antenna 3 is completed. Correspondingly, after the box body is bonded, the antenna 3 and the radio frequency tag 2 are hidden between the upper rubber plate 13 and the side plate 16, so that the possibility that the RFID tag 2 is manually stripped and damaged can be reduced, and the RFID anti-channel conflict function can be realized. For example, in the stages of warehousing and ex-warehouse of warehouse management, information carried by the radio frequency tag on the radio frequency packaging box can be read based on radio frequency reading equipment, so that whether the objects to be warehoused and ex-warehouse are accurate or not can be determined.
An example of palletization is shown in figure 7. Because the radio frequency tag 2 and the antenna 3 are positioned at the corner joint of the radio frequency packaging box, under a group reading environment, such as batch stacking on a tray, the radio frequency performance of the radio frequency tag is less influenced by articles which have serious obstruction to electromagnetic wave radiation, such as metal, liquid and the like in the intelligent packaging.
In the embodiment of the application, the box body material of the radio frequency packaging box can be corrugated board or other paperboards, and can be specifically set according to requirements.
In the embodiment of the application, the impedance matching network and the antenna of the radio frequency tag are processed separately, the etching or laser engraving process can be adopted for the impedance matching network part with higher processing precision requirement, and the die cutting process is adopted for the antenna part with lower processing precision requirement. Meanwhile, the size of the impedance matching network part is small, so that the efficiency of a flip-chip (flip-chip) process can be greatly improved, and the processing cost is further reduced.
The radio frequency performance of the embodiment of the application is less influenced by the environment. The antenna of one example is an omnidirectional antenna composed of a three-dimensional C-shaped structure, is slightly influenced by articles inside the intelligent package (even if liquid and metal exist), and can read the RFID tag from multiple directions to obtain good radio frequency performance. Another example antenna and rf tag is mounted at the corner junction of a carton, whose rf performance in a group reading environment is less affected by items in the carton that have a significant obstruction to electromagnetic wave radiation, such as metal and liquid.
And the impedance matching network is formed by connecting two inductive microstrip circuits in parallel, and is less influenced by the surface metallization pattern of the package and internal articles compared with the inductive impedance matching network formed by a conventional L-shaped impedance matching network.
