Description

technical field

[0001] The present invention relates to the field of communication, in particular to a mobile terminal and an NFC antenna. Background technique

[0002] The NFC (Near Field Communication) antenna in the related art is composed of a circuit substrate and a planar coil. When two mobile terminals with NFC antennas perform P2P (peer-to-peer network) operations, the two NFC antennas will interfere with each other, resulting in a large shift in resonance frequency, which affects the sensitivity and success rate of communication. Contents of the invention

[0003] The present invention is based on the discovery of the following facts and problems by the inventor of the present application: the inventor has conducted a large number of experiments and analyzed the test results to obtain that the mutual influence of two NFC antennas increases with the In the initial stage when the facing area of ​​the two NFC antennas is gradually decreasing, the reduction of the re...
