[0020] like Figure 1 、 2 As shown, an optional embodiment of the present invention provides a circuit board with a built-in NFC antenna, including a PCBA board 1 and a PCBB board 2 electrically connected to each other, and also includes an NFC module 3. The NFC module 3 includes an NFC chip 30 arranged on the PCBA board and an NFC antenna 31 printed inside the PCBB board body.

[0021] In this embodiment, the NFC antenna is arranged inside the PCBB board, thereby reducing the occupied space and strengthening the protection of the NFC antenna.

[0022] like Figure 2As shown, in another optional embodiment of the present invention, the PCBB board 2 includes an upper plate body 21 and a lower plate body 22, and an NFC antenna 31 is placed between the upper plate body 21 and the lower plate body 22. The upper plate body 21 and the lower plate body 22 are stacked and formed as one piece, and the NFC antenna 31 is arranged circumferentially along the edge inside the lower plate body 22.

[0023] In this embodiment, the PCBB board 2 is divided into an upper plate body 21 and a lower plate body 22, so that the NFC antenna 31 can be installed therein. At the same time, the upper and lower stacked integrally formed structure can also protect the NFC antenna 31. At the same time, because the NFC antenna 31 is arranged along the circumference of the inner edge of the lower plate body 22, the overlap between the NFC antenna 31 and the components integrated on the PCBB board 2 is reduced, thereby avoiding poor working sensing and increasing the sensing range.
