The antenna body 22 is composed of a radiation element 221, an antenna ground 222, a feed pin 223 connected with a radio frequency chip, a short-circuit pin 224 and a gap compensation structure 225. The gap compensation structure is not covered by a metal layer, so that a gap is formed, and the adaptability to objects contained in the packing box is improved, such as the adaptability of various metal objects in the packing box is improved. As shown in fig. 2, the gap compensation structure 225 is a stepped gap compensation structure, and in actual processing, the gap compensation structure may also be in a trapezoidal shape, a triangular shape, or the like, and may be specifically adjusted based on requirements.
When the radio frequency tag 2 is pasted on a packing box, the part where the antenna ground 222 is located is pasted on the inner side of the side paper board of the packing box, and the parts where the short circuit pin 224 and the feed pin 223 are located are pasted on the inner side of the top paper board of the packing box. As shown in fig. 2, the antenna ground 222 is separated from the radiation element 221, the feed pin 223 and the short-circuit pin 224 by a boundary line, i.e. after the rf tag is bent, the antenna is located on one side of the boundary line, and the short-circuit pin, the feed pin and the radiation element are located on the other side of the boundary line, which is used to mark the boundary position of the bent structure, and may not exist in the actual process. Of course, in some scenarios, a boundary may also be provided to facilitate bending, which is not limited in the embodiments of the present application. Wherein the gap compensation structure 225 may be arranged to be entirely located below the dividing line; it may be provided that a part is located below the dividing line and another part is located above the dividing line.
In one example, the portions below the dividing line (antenna ground 222, a portion of the gap compensation structure 225) are affixed to the inside of the side sheet of the package, and the portions above the dividing line 20 (the radiating element 221, the feed pin 223, the shorting pin 224, and another portion of the gap compensation structure 225) are affixed to the inside of the top sheet of the package.
Based on the structure of the radio frequency tag, the radio frequency tag can form a three-dimensional structure after being bent, and the radio frequency tag with the three-dimensional structure can effectively reduce the obstruction of metal in other surrounding packing boxes to electromagnetic wave radiation, so that the integral reading rate of a radio frequency tag system is improved.
In the embodiment of the application, the distance a between the radio frequency tag 2 attached to the radio frequency packaging box and the vertical edge of the packaging box 1 is the vertical edge with the minimum distance from the packaging box 1. The distance a has the following characteristics:
wherein, lambda is the operating frequency of radio frequency antenna to when the content 3 of packing box is the metal object, radio frequency label can obtain good radio frequency performance.
Wherein, the metal articles carried in the radio frequency packaging box comprise metalized packaging articles. Such as aluminum foil packaged products, products wrapped by aluminum foil heat-insulating materials and the like.
After metal articles are loaded in the radio frequency packaging box and the box is sealed, the part, attached to the top paperboard, of the radio frequency tag is located between the attached top paperboard 11 and the other top paperboard 12, so that the radio frequency chip is protected by the two layers of paperboards, and the possibility of failure of the radio frequency tag can be reduced. And the radio frequency tag is in an invisible state after the box is sealed, so that the radio frequency tag can be prevented from being maliciously peeled off, and the function of anti-channel conflict inspection in the field of supply chain management can be effectively realized by combining a hidden radio frequency reading device. 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.
The rf chip 23 is electrically connected to the feeding pin 223 through the anisotropic conductive adhesive. The feed pin 223, the shorting pin 224 and the gap compensation structure 225 form an impedance matching network of the rf chip. Namely, the impedance matching network of the antenna body is composed of a T-match structure consisting of a feed pin and a short-circuit pin and a stepped gap compensation structure.
As shown in fig. 4, when the metal object 3 in the rf packaging box approaches the rf tag, electromagnetic coupling is generated between the antenna ground of the antenna body and the metal object, and a mirror current is generated on the metal layer of the metal object, so that the metal layer of the metal object is used as a supplementary ground of the antenna body to increase the antenna gain.
Meanwhile, the real part and the imaginary part of the impedance of the antenna are simultaneously increased due to the influence of the metal, which may cause the reduction of the center frequency of the RFID tag and the deterioration of the radio frequency performance. The distance b is the distance between the part of the radio frequency tag attached to the inner side of the paperboard on the side of the packing box and the metal article in the packing box, and the distance c is the distance between the part of the radio frequency tag attached to the inner side of the paperboard on the top of the packing box and the metal article in the packing box. In view of the above problem, the antenna body of the rf tag of the embodiment of the present application has the gap compensation structure 225, and the series inductance introduced by the gap compensation structure 225 can greatly reduce the impedance influence of the metal object on the antenna body. When the distances b and c are smaller, for example, the packing box is full of articles, the real part and the imaginary part of the impedance of the antenna body are increased, and the gap compensation structure of the embodiment of the application is affected by the fact that b and c are smaller at the same time, so that the series inductance introduced by the gap compensation structure is reduced, and the degree of the increase of the real part and the imaginary part of the impedance is reduced, and vice versa. Therefore, the gap compensation structure can effectively improve the adaptability of the radio frequency tag to various metal articles in the radio frequency packaging box.
In the embodiment of the present application, the end of the radiating element 221 of the antenna body has a curved structure, and as shown in fig. 2, the end has a loop structure. Therefore, the end of the radiation oscillator with the capacitive load is provided with metal charges stored in a large area, and the physical size of the radiation oscillator can be effectively reduced. Meanwhile, the radiation directivity of the antenna formed by the curve structure is changed, so that the RFID tag can still be read by radio frequency reading and writing equipment in the direction of spacing metal objects, and the stability of radio frequency performance is ensured.
