Embodiment Construction

[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0035] When two mobile terminals with NFC antennas perform P2P operations, the size of the facing area of ​​the two NFC antennas has a significant impact on the sensitivity and success rate of communication. The mutual influence of the two NFC antennas decreases with the decrease of the facing area of ​​the two NFC antennas. Due to the symmetrical structure of the traditional NFC antenna, when two mobile terminals are placed back to back, the two NFC antennas just overlap, and the mutual interference between the two NFC antennas ...

Abstract

The invention discloses a mobile terminal and an NFC antenna. The mobile terminal includes: a terminal body; an NFC antenna, the NFC antenna is arranged on the back of the terminal body, and the NFC antenna passes through the The longitudinal centerline and / or the transverse centerline, and the parts of the NFC antenna located on both sides of the longitudinal centerline and / or the transverse centerline on the back of the terminal body are asymmetrical. The mobile terminal according to the embodiment of the present invention has a small resonance frequency shift when performing P2P operations, and has the advantages of high communication sensitivity, high communication success rate, and strong communication capability.

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...
