The electronic tag of the present application includes an antenna layer 1, a substrate 2, a rechargeable power supply layer 3, and a metal chassis 4 arranged from top to bottom. The substrate 2 may be a substrate commonly used for PCB, and the antenna layer 1 may be formed on the substrate 2 by a laser etching process, which is a mature technology and will not be described herein. It should be noted that, the ratio of the thickness of the antenna layer 1 to the thickness of the substrate 2 and other components shown in the drawings is only for convenience of illustration, and is not intended to limit the ratio of each part of the actual product, in which the antenna layer 1 is usually um-level, and is far smaller than the thickness of the substrate 2, and it can be understood in combination with a common PCB board.
Referring to fig. 2 to 4, the active tag portion L1 of the present application includes: the microwave RFID processing device comprises a microstrip antenna 9 and a microwave induction feedback loop 10 which are formed on the upper surface of a substrate 2, a chargeable power layer 3 which is configured on the lower side of the substrate 2, and a microwave RFID processing chip 11 which is connected in series with the microwave induction feedback loop 10; the metal bottom plate 4 is arranged on the lower side of the power supply layer 3; the power supply layer 3 is electrically connected to the microwave RFID processing chip 11 for supplying power to the RFID processing chip 11. Referring to fig. 5, the microwave induction feedback loop 10 is in a ring shape, and has a connection port 10A for connecting the microwave RFID processing chip 11, and the power layer 3 is used for supplying power to the microwave RFID processing chip 11 when the microwave RFID processing chip 11 is configured at the connection port 10A. The impedance of the microwave induction feedback loop 10 can be correspondingly adjusted according to the specific schemes of the microstrip antenna 9 and the microwave RFID processing chip 11. The connection between the microwave RFID processing chip 11 and the connection port 10A may be a common welding method. The microwave-induced feedback loop 10 is not in direct communication with the microstrip antenna 9, but is energy-transmitting in a coupled manner.
The passive tag portion L2 includes: the ultra-high frequency antenna comprises two axisymmetric ultra-high frequency antennas 5 and 6 which are formed on the upper surface of a substrate 2 and can receive ultra-high frequency signals, an ultra-high frequency induction feedback loop 7 which is formed on the upper surface of the substrate 2 and is positioned between the two first antennas 5 and 6, and an ultra-high frequency RFID processing chip 8 which is connected in series with the ultra-high frequency induction feedback loop 7; the ultrahigh frequency antennas 5 and 6 are electrically connected to the metal base plate 4; the ultra-high frequency RFID chip 8 is electrically connected to the power layer 3, and the ultra-high frequency RFID chip 8 can convert the ultra-high frequency signals received by the ultra-high frequency antennas 5 and 6 into electric energy to be stored in the rechargeable power layer 3. The uhf antenna of the present embodiment is a PIFA antenna, which is symmetrically disposed on the left and right sides of the upper surface of the substrate 2. The PIFA antenna structure has larger receiving area, can receive more external signal energy, and the symmetrical double PIFA antenna structure can ensure the maximum energy receiving efficiency of the symmetrical center where the ultra-high frequency induction feedback loop is positioned. The uhf inductive feedback loop is not directly connected to the PIFA antenna, but is coupled for energy transfer. The uhf inductive feedback loop 7 is also substantially annular. The connection between the ultra-high frequency RFID chip 8 and the ultra-high frequency inductive feedback loop 7 may be similar to the connection between the microwave RFID processing chip 11 and the microwave inductive feedback loop 10.
The passive tag portion L2 can receive signals having frequencies of 917-925Mhz, and the passive tag portion L2 is compatible with ISO/IOE 18000-6C, EPC Class 1Gen 2 protocol standards. The active tag portion L1 can receive signals at frequencies between 2.4GHz and 2.45GHz. The ultra-high frequency RFID processing chip 8 is, for example, an FM13UF02J chip or an FM13UF02G chip.

The impedance of the uhf inductive feedback loop 7 may be correspondingly adjusted according to the specific scheme of the uhf antennas 5, 6 and the uhf RFID processing chip 8. Referring to fig. 2, in an embodiment, when the uhf RFID processing chip 8 is an FM13UF02J chip, the uhf antenna may be a PIFA antenna, and the uhf inductive feedback loop 7 may be the structure in fig. 7, where the uhf inductive feedback loop 7 includes a middle portion of a cuboid, two L-shaped edge portions disposed on two sides of the block portion and symmetrically disposed, and a gap is formed between the lower sides of the two edge portions and the middle portion. Referring to fig. 3, in an embodiment, when the microwave RFID processing chip 11 is an nRFl01 chip, the microstrip antenna 9 and the microwave induction feedback loop 10 may be the structure in fig. 3, where the microstrip antenna 9 has a rectangular block portion and a strip portion connected to the block portion, and the microwave induction feedback loop 10 is generally in a square structure with an opening.
The active tag portion has an active processing circuit 12, which may be formed on the lower surface of the substrate 2; when the microwave RFID processing chip 11 is disposed at the connection port 10A, the power supply layer 3 is electrically connected through the active processing circuit 12. The power supply layer 3 can supply the microwave RFID processing chip 11 with the electric energy required for operation through the active processing circuit 12.

The active processing circuit 12 may also be a microwave RFID processing chip 11 or integrated with the active processing circuit 12.
Referring to fig. 6, in one embodiment, the rechargeable power source layer 3 includes a rechargeable battery 3B. The power layer 3 further comprises a foam board 3A, and the rechargeable battery 3A may be disposed on the foam board 3B, specifically, the foam board 3A may have a recess adapted to the rechargeable battery 3B, and the rechargeable battery may be disposed in the recess. The rechargeable battery 3A has two terminals which are connected to the microwave-induced feedback loop 10 when the rechargeable battery 3A is arranged in the recess of the foam board 3A. The foam board 3A provides protection for the rechargeable paper battery while allowing the overall structural height to be increased. When the electronic tag is used, the metal bottom plate 4 is a part close to the surface of the material, and when the material is made of metal, the whole structural height is increased due to the foam plate, so that the anti-metallic property of the tag can be improved. The rechargeable battery 3B is, for example, a rechargeable button battery or a rechargeable paper battery.
The structural size of the electronic tag can be 50mm by 4mm.
The reading distance of the passive tag part of the electronic tag can cover 0-5m, the reading distance of the active tag part can cover 0-20m, and the application of checking, searching materials and the like in the RFID warehouse management system can be met.
In other embodiments, the rechargeable power source layer 3 may be selected to be capable of wireless charging.
The ultrahigh frequency antenna with the passive tag part is two groups, the microstrip antenna with the active tag part is one group, and the whole receiving area of the ultrahigh frequency antenna is larger than that of the microstrip antenna. Because the passive tag part is passive, the two groups of ultrahigh frequency antennas have larger receiving areas, thereby being beneficial to improving the energy conversion amount in unit time. Whereas the active tag portion itself has a power plane for power supply, it does not require a microstrip antenna having a large area. The existing RFID antenna adopts a dipole single-layer structure, and can be designed only in a non-metal environment, when the antenna is attached to a metal surface, the antenna of the tag is changed in impedance matching, radiation efficiency and directivity, so that the reading distance of the tag is rapidly reduced, and even the tag is difficult to read, namely the existing RFID antenna is poor in metal resistance. The ultra-high frequency antenna and the microstrip antenna of the PIFA type technical proposal all form a multilayer three-dimensional structure with the substrate, the power supply layer and the metal bottom plate, and the PIFA type antenna can normally work in a metal environment and a nonmetal environment and has better anti-metallic property.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, and various modifications and variations may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
