Embodiment Construction

[0013] In order to make the purpose, technical solutions and advantages of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0014] attached figure 1 It is a schematic diagram of the metal back cover 1 and the metal back cover 2 of the mobile phone of the present invention without connecting points. The metal back shell includes a metal back cover 1 and a metal back cover 2, wherein the length of the metal back cover 1 is 40 mm, and the width is 8 mm. The distance between the metal back cover 1 and the metal back cover 2 is 1.3 mm. The metal back cover 2 has a length of 110mm and a width of 40mm. The NFC antenna is placed inside the metal back shell. The metal back cover 1 and the metal back cover 2 are connected through plastic gaps to form an integral metal back shell.

Abstract

The invention discloses an antenna for mobile phones with a metal back shell and a mobile phone using the same. The antenna comprises an all-metal back shell, an NFC antenna, and a PCB motherboard. The all-metal back shell includes a metal back cover 1 and a metal back cover 2 which are adjacent to each other. There is a gap between the metal back cover 1 and the metal back cover 2. The NFC antenna is arranged on the inner side of the all-metal back shell. The PCB motherboard is arranged on the inner side of the NFC antenna. The antenna is characterized in that a metal connection point is arranged at the midpoint of the gap between the metal back cover 1 and the metal back cover 2. According to the antenna for mobile phones with a metal back shell and the mobile phone using the same, the NFC antenna has good communication performance.

Description

technical field [0001] The invention relates to the application of an NFC antenna for a portable mobile terminal, in particular to an NFC antenna for a metal back shell mobile phone. Background technique [0002] With the rapid development of mobile communications, the forms of mobile phones are becoming more and more diverse, and mobile phones with metal back covers are more beautiful in appearance and feel better. From a structural point of view, compared with plastics such as PC and ABS, metal back covers The back shell of the material is also more wear-resistant. The traditional NFC antenna can only be placed on the plastic back shell, and when it is applied on the traditional metal back shell, the metal back shell has a blocking effect on the signal, and the NFC antenna cannot work normally. The use of metal materials improves the aesthetics and durability of the product, but it brings greater challenges to the design of NFC antennas. Traditional antenna forms can no ...
