Description
Technical field
The utility model relates to a kind of antennas, more particularly, to a kind of and diversity antenna common antenna cabling NFC antenna.
Background technique
NFC be it is a kind of provide easily, safety and the wireless connection technology that rapidly communicates, NFC has that distance is close, bandwidth is high
With the characteristics of low energy consumption.Secondly, NFC is compatible with existing contactless smart card technology, have become to obtain more and more masters at present
The official standard for wanting manufacturer to support.Again, NFC or a kind of short-range connection protocol, provide various equipment rooms easily, safety,
It communicates rapidly and automatically.Compared with other connection types in wireless connection field, NFC is a kind of secret communication of short distance
Mode, NFC play huge effect in the fields such as gate inhibition, public transport, mobile-phone payment.
Most current mobile phone is built-in with NFC chip, and matched NFC antenna is arranged, and NFC antenna is all independent
Design, and certain space need to be occupied, but mobile phone is increasingly stringenter thickness requirement at present, also increasingly focus on cost.Therefore
Current being separately provided for NFC antenna limits further decreasing for mobile phone thickness, also limits further decreasing for manufacturing cost.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of and diversity day to overcome the problems of the above-mentioned prior art
The NFC antenna of line common antenna cabling.
The purpose of this utility model can be achieved through the following technical solutions: a kind of and diversity antenna common antenna cabling
NFC antenna, the rear shell including mobile terminal further includes that NFC antenna and diversity antenna share cabling and two inductances: day
Line inductance a and inductance b, inductance a and inductance b are separately positioned at two feed points of NFC antenna.This is at two
Inductance is used to be promoted the inductance of NFC antenna, increases the physical length of antenna with this, improves the operational efficiency of antenna.
Further, the NFC antenna connects NFC chip by NFC antenna match circuit.
Further, the inductance a and inductance b being arranged at two feed points of the NFC antenna, are separately connected
NFC antenna match circuit both ends, forming circuit.
The NFC antenna is a part or entirety of diversity antenna cabling, a feedback in two feed points of NFC antenna
Point is set near the feeding point of diversity antenna, or shares a feed point with diversity antenna；Another feed point is set to diversity day
The end of line cabling, or wherein one section in diversity antenna cabling.
Further, NFC antenna and diversity antenna share the width of cabling for 2-5mm, length 10-50mm, as far as possible
Increase the width and length of cabling, so as to improve the efficiency of antenna.
Further, the NFC antenna and diversity antenna share cabling and the screen plane of mobile terminal is pressed from both sides at 90 degree
Angle.
The rear shell is non-metallic material or diversity antenna region is nonmetallic materials, wherein non-metallic material master
It will be using ceramics or glass.
In addition, NFC antenna does not need to control by other external devices with diversity antenna, NFC antenna system can with point
Collect antenna system and share an antenna cabling as radiator,
Compared with prior art, the NFC antenna cabling in the utility model and diversity antenna cabling are under nonmetallic environment
A cabling is shared, so that NFC antenna is not required to individually designed, cost has been saved, has reduced thickness, and model structure is simple,
Mobile phone space is saved.
