Abstract

The invention discloses a metal rear shell-based NFC antenna structure and a manufacturing method thereof. The metal rear shell-based NFC antenna structure comprises a metal rear shell, an antenna support body, an antenna coil, a metal channel and a plastic insulating material. The metal rear shell-based NFC antenna structure is unique in design and novel in structure; the metal rear shell of communication equipment is utilized by an NFC antenna coil; and a helical antenna coil is cut on the outer side surface of the metal rear shell. The interference to a magnetic field generated by the NFC antenna caused by vortex of a metal back cover is effectively reduced, so that good electrical property between the NFC antenna and a reader-writer in a working process is ensured. The metal rear shell-based NFC antenna structure is simple and beautiful, can be widely applied to communication equipment with the metal rear shell and meets the requirements of a mobile payment function.

Description

technical field

[0001] The invention relates to the technical field of mobile phone antenna manufacturing, in particular to an NFC antenna structure based on a metal back shell and a manufacturing method thereof. Background technique

[0002] With the development of the near-field communication function of mobile devices at this stage, the NFC (Near Field Communication short-distance wireless communication technology) function will be configured in more handheld devices, which will prompt more and more research on the design of NFC antennas. attention. In traditional NFC antenna applications, it is generally chosen to place the FPC, that is, the NFC antenna radiator on the battery. At the same time, in order to reduce the negative impact of the battery on the NFC antenna, it is necessary to add a piece of ferrite between the FPC and the battery. The above-mentioned NFC antenna design solution is only suitable for the case where the back cover of the handheld device is made ...
