Problems solved by technology

In addition, due to the development trend of metallization of the back shell of the mobile terminal, the radiation area of ​​the NFC antenna is getting smaller and smaller, and it is difficult to guarantee the evasion design of the NFC antenna to the metal back shell. These pose severe challenges to the design of the NFC antenna in the mobile terminal. challenge

Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations. In addition, the character " / " in this article generally indicates that the contextual objects are an "or" relationship.

[0021] It should be noted that, in order to clearly ...

Abstract

The invention provides a mobile terminal, relates to the technical field of communication, and is used for increasing a radiating area of an NCF (Near Field Communication) antenna in the mobile terminal to improve the performance of the NCF antenna. The mobile terminal comprises a rear housing and a metal frame; a flexible printed circuit board is attached inside the rear housing; the flexible printed circuit board is provided with a first feed point, a second feed point, a first connection point and a second connection point; the first feed point is electrically connected with the first connection point; the second feed point is electrically connected with the second connection point; the first feed point and the second feed point are overlapped with a metal area; the first connection point and the second connection point are overlapped with a non-metal area; a third connection point and a fourth connection point are arranged on the metal frame; the third connection point is electrically connected with the first connection point; the fourth connection point is electrically connected with the second connection point; and the metal frame among a first metal routing, a second metal routing, the third connection point and the fourth connection point is formed into an annular loop, thereby realizing receiving and sending of NFC signals. The mobile terminal provided by the invention is used in manufacturing of the mobile terminal.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a mobile terminal. Background technique [0002] With the continuous development of communication technology, users also put forward higher requirements on mobile terminals, not only the requirements on the functions that can be realized by the mobile terminals are getting higher and higher, but also the requirements on the appearance of the mobile terminals are getting higher and higher. Among them, in terms of functions, near-field communication technology (full name in English: Near Field Communication, NFC for short) is more and more compatible with NFC technology due to its convenience, ease of use, and more intuitive features. In terms of appearance, the metal back shell has been favored by more and more users in recent years due to its unique texture and luster. [0003] However, there are certain contradictions in the implementation of NFC technology a...
