Problems solved by technology

The inductance in the NFC antenna in the prior art adopts a metal frame. The performance of the NFC antenna depends entirely on the diversity community part (metal frame), but due to the limitation of the diversity scheme with other antennas, the length of the NFC antenna of the community is limited. As a result, the performance of the NFC antenna is poor

Embodiment Construction

[0029] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. 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.

[0030] In order to facilitate the understanding of the mobile terminal provided by the embodiment of the present application, the mobile terminal provided in the embodiment of the present application will first be described below. There is a first antenna, such as a GPS antenna or a WiFi antenna, a main antenna or a diversity antenna, etc., and when set, the first antenna and the NFC antenna are a common antenna. In order to improve the...

Abstract

The invention provides a mobile terminal. The mobile terminal comprises an NFC antenna; the NFC antenna comprising a feed source, and an inductor and a capacitor which are connected with the feed source and are connected in parallel; the NFC antenna further comprises one or more from a first distributed inductor, a second distributed inductor, a third distributed inductor and a fourth distributedinductor; the first distributed inductor is positioned between the feed source and the inductor; the second distributed inductor is positioned between the inductor and a first grounding point; the third distributed inductor is positioned between the feed source and the capacitor; the fourth distributed inductor is located between the capacitor and a second grounding point, the inductor comprises alumped inductor and a metal section connected with the lumped inductor in series, the distributed inductors can enlarge the loop area of the NFC antenna, then the magnetic flux is increased, the coupling energy is increased, and therefore the performance of the NFC antenna is improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a mobile terminal. Background technique [0002] At present, with the rapid development of smart terminals (such as mobile phones and tablet computers), NFC functions are becoming more and more common. NFC functions are card simulation mode (that is, used as IC cards such as credit cards and bus cards), card reader mode and point-to-point mode. (That is, data interaction between terminals, similar to Bluetooth), so after turning on the NFC function, the smart terminal will face many IC cards and POS machines, which need better performance to be compatible. The inductance in the NFC antenna in the prior art adopts a metal frame. The performance of the NFC antenna depends entirely on the diversity community part (metal frame), but due to the limitation of the diversity scheme with other antennas, the length of the NFC antenna of the community is limited. As a ...
