Problems solved by technology
The first method requires a large NFC antenna area, which cannot be realized on an all-metal body
Although the second method solves the shielding effect of the metal back shell on the NFC antenna by opening holes and gaps, the through holes and gaps open affect the integrity of the metal back shell and destroy the beauty and strength of the metal body.
This invention needs to install the NFC antenna near the camera, which has great design limitations

Embodiment Construction
[0020] The invention discloses a method for manufacturing an all-metal mobile phone NFC antenna.
[0021] The technical solutions in the present invention are clearly and completely described below in conjunction with the accompanying drawings. What has been described is only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0022] Such as figure 1 As shown, a method for manufacturing an all-metal mobile phone NFC antenna is illustrated, and the specific content includes the following steps:
[0023] The first step is to make a circular metal frame 101 . Ring metal frame 101 two ends are cut off, and the independent metal edge bar of annular metal frame 101 top is selected as the radiator or a part thereof of metal small antenna 107, an...

The invention discloses a manufacturing method of an all-metal mobile phone NFC antenna. The invention relates to the technical field of an NFC antenna. According to the manufacturing method, a metal frame is integrated with a metal back cover through in-mold injection molding, and furthermore an NFC antenna coil is manufactured on an annular plastic member. Therefore an NFC antenna function can be realized on the all-metal mobile phone without mounting the NFC antenna coil next to a camera lens hole or embedding a large-area plastic member into the metal back cover. Therefore the thickness of the mobile phone can be reduced without integrity reduction or strength reduction of a metal mobile phone housing. Furthermore the metal frame can be cut off. The manufacturing method is mainly used for a main antenna, a diversity antenna, a GPS+WiFi antenna, etc.
Description
technical field [0001] The invention relates to the technical field of antennas in wireless communication terminal equipment, in particular to a method for manufacturing an all-metal mobile phone NFC antenna. Background technique [0002] Smartphones, PDAs, mobile PCs and other mobile terminals are hereinafter collectively referred to as "mobile phones". A mobile phone with NFC function can be used as an RFID passive tag or as an RFID reader. With the popularization of applications such as mobile payment, NFC function will become the standard configuration of smart phones. The NFC antenna is usually acted by a metal coil, and the metal coil can be printed on the FPC, or it can be made on the plastic part by using LDS technology. At present, the built-in NFC antenna of the mobile phone has the following two processing methods: the first method is to install the NFC antenna on the plastic of the mobile phone back cover; hole and a gap from the through hole to the edge of th...
