Abstract

The invention discloses an NFC antenna assembly and an electronic device. The NFC antenna assembly comprises an NFC driving chip, NFC antenna radiator which is connected with the NFC driving chip, anda coupling piece which is located in the radiation range of the NFC antenna radiator; the coupling piece and the NFC antenna radiator are spaced; and the coupling piece and the NFC antenna radiator can be coupled with each other, so that the current passing through the NFC antenna radiator and the current passing through the coupling piece are consistent in direction. According to the NFC antennaassembly, the coupling piece spaced from the NFC antenna radiator is added in the radiation range of the NFC antenna radiator, and the coupling piece and the NFC antenna radiator can be coupled witheach other, so that the current passing through the NFC antenna radiator and the current passing through the coupling piece are consistent in direction, the magnetic field intensity can be effectivelyenhanced, and the performance of the NFC antenna assembly is improved. And meanwhile, the number of turns of an NFC antenna radiator coil is reduced, so that the weight of a whole machine is reduced.In addition, the coupling piece can be independently processed, is flexible and convenient in design, and can be placed at different positions as required.

Description

technical field [0001] The present application relates to the technical field of NFC antennas, in particular to an NFC antenna assembly and electronic equipment. Background technique [0002] In related technologies, NFC (Near Field Communication, NFC for short) antennas have been increasingly applied to electronic devices such as mobile phones. In order to improve the radiation intensity of the NFC antenna, in the prior art, the performance is mainly improved by arranging a multi-turn coil. , However, the way of multi-turn coils leads to an increase in the quality of the NFC antenna. Contents of the invention [0003] The present application proposes an NFC antenna assembly. The NFC antenna assembly has a strong magnetic field strength and is conducive to reducing the number of radiator coils of the NFC antenna. [0004] The present application also proposes an electronic device, which includes the above-mentioned NFC antenna assembly. [0005] The NFC antenna assembly...
