Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As described in the background section, because the existing NFC antennas are all fixed planar antenna structures, when applied to electronic devices, a large planar layout space is required, which brings great challenges to the layout of the electronic devices and is not favorable for the development of miniaturization of the electronic devices.

It should be noted that, in the embodiment of the present invention, the strength of the signal radiated by the NFC antenna is related to the coverage area of the predetermined shape, and the larger the coverage area of the predetermined shape is, the stronger the signal strength of the NFC antenna is, and the better the performance of the NFC antenna is.
