[0024] like Figure 1 and Figure 2 As shown, the RFID electronic tag 100 provided in the embodiment of the present application includes a PCB 101 and an IC chip 102, wherein:

[0025] The PCB 101 includes a chip mounting portion 1011 and an onboard antenna portion 1012 ;

[0026] The chip mounting portion 1011 is used to mount the IC chip 102;

[0027] The onboard antenna portion 1012 includes an antenna integrated with the PCB 101 . The antenna of the onboard antenna portion 1012 is electrically connected to the chip mounting portion 1011 to achieve electrical connection with the IC chip 102 .

[0028] That is, in this embodiment of the present application, the PCB 101 on which the IC chip 102 is mounted and the antenna are integrated. When manufacturing the PCB 101, the antenna can be fabricated onto the outside of the chip mounting portion 1011 and connected to the chip mounting portion 1011. Thus, when manufacturing the RFID tag 100, it is only necessary to mount the IC chip 102 onto the chip mounting portion 1011 on the PCB 101 and connect the antenna to the PCB 101.

[0029] It should be noted that, in the embodiments of the present application, the present application does not specifically limit the specific position of the antenna in the PCB 101. As long as the antenna and the PCB 101 are integrated into one structure, they are within the scope of protection of the present application.

[0030] Furthermore, in the embodiment of the present application, PCB 101 can be a single-layer board structure or a multi-layer board structure; PCB 101 can be a traditional rigid circuit board or a flexible circuit board; the base material of PCB 101 can be epoxy resin, polyimide, ceramic substrate, etc., which is not limited in this application.

[0031] Furthermore, in the embodiment of the present application, the antenna can be arranged in a single layer or in a multi-layer layout, and the present application does not limit this.

[0032] Furthermore, in the embodiment of the present application, the specific method of installing the IC chip 102 on the PCB 101 can be bonding, binding or flip-chip welding, etc., and the present application does not limit this.

[0033] It can be seen that the solution provided in the embodiment of the present application simplifies the structure of the RFID electronic tag, thereby simplifying the production process of the RFID electronic tag, improving production efficiency, and increasing the production yield, that is, improving production quality.

[0034] In the embodiment of the present application, the number of antennas in the onboard antenna portion 1012 is at least one, and the antennas are located on at least one side of the chip mounting portion 1011 .

[0035] That is, the number of antennas in the onboard antenna unit 1012 may be one, or two or more, which may be determined according to the number of antenna interfaces of the IC chip 102 .

[0036] The antenna of the onboard antenna unit 1012 may be arranged on one side of the chip mounting portion 1011 , may be arranged on multiple sides of the chip mounting portion 1011 , or may be arranged around the periphery of the chip mounting portion 1011 .

[0037] In a specific embodiment, the number of antenna interfaces of the IC chip 102 is 2, such as Figure 2 As shown, the onboard antenna portion 1012 also has two antennas, including a first antenna 201 and a second antenna 202 . The first antenna 201 and the second antenna 202 are located on opposite sides of the chip mounting portion 1011 .

[0038] use Figure 2 The length of the PCB 101 is greater than 10 mm and less than 60 mm. Preferably, the length of the PCB 101 is greater than 25 mm and less than 40 mm. For example, the length of the PCB 101 can be 30 mm.

[0039] Disposing the first antenna 201 and the second antenna 202 on opposite sides of the chip mounting portion 1011 can reduce interference between the antennas and ensure the performance of the RFID electronic tag 100 .

[0040] Of course, in other specific implementation schemes, the first antenna 201 and the second antenna 202 may also be located on one side of the chip mounting portion 1011 , or on two adjacent sides of the chip mounting portion 1011 , which will not be described in detail here.

[0041] exist Figure 2 In the illustrated embodiment, the onboard antenna portion 1012 may extend along the length of the PCB 101 , and the antenna of the onboard antenna portion 1012 may be repeatedly bent in various forms.

[0042] exist Figure 2 In the illustrated embodiment, the width of the onboard antenna portion 1012 is partially smaller than the width of the chip mounting portion 1011 .

[0043] Of course, in other specific implementation schemes, the width of the onboard antenna portion 1012 may also be smaller than the width of the chip mounting portion 1011 .

[0044] By reducing the width of the onboard antenna portion 1012 , the area of ​​the RFID electronic tag 100 can be reduced, making the RFID electronic tag 100 suitable for more usage scenarios.

[0045] In the embodiment of the present application, the copper thickness of PCB 101 is greater than 0.5 ounces. Preferably, the copper thickness of PCB 101 is 2 ounces. Using a thicker copper thickness not only ensures the performance of RFID tag 100, but also further enhances the strength and toughness of onboard antenna 1012.

[0046] The present application also provides a tire, comprising the above-mentioned RFID electronic tag 100.

[0047] Compared to existing RFID tags, the RFID tag 100 provided in this embodiment not only has a simpler production process, but also has a smaller footprint and a thinner thickness, making it suitable for a wider range of scenarios. Tires using this RFID tag 100 also have higher reliability.
