Mobile terminal embodiment:
The present embodiment introduces antenna assembly 1 set-up mode on mobile terminals as a example by mobile phone.As it is shown in figure 1, antenna
Device 1 designs nonmetal back cover 2 inwall at mobile phone.In order to optimize the quality factor of antenna assembly 1, it is also possible to corresponding to antenna
Device 1 arranges ELECTROMAGNETIC REFLECTION device (not shown), and to increase the antenna Net long wave radiation distance in certain direction, ELECTROMAGNETIC REFLECTION fills
Putting can be such as ferrite, arranges position and is generally located at the inner side (i.e. closer to the side of interior of mobile phone) of antenna assembly 1,
That is: antenna assembly 1 is between ELECTROMAGNETIC REFLECTION device and back cover 2.
For other mobile terminal, the set-up mode of antenna assembly 1 can refer to mobile phone.
In the terminal, according to functional requirement, configurable WPC chip and/or FM chip, and NFC chip and/or
RFID chip, these functions are then supported by antenna assembly 1.Below by way of several specific embodiments knot to antenna assembly 1
The connected mode of each functional chip describes in detail with mobile terminal for structure and antenna assembly 1.
Antenna assembly first embodiment:
Refering to Fig. 2, typically applying as one, the antenna assembly 1 in the present embodiment achieves WPC function and NFC function
Multiplexing.Correspondingly, need in the terminal to arrange WPC chip 3 and NFC chip 4, to support WPC function and NFC function.
This antenna assembly 1 uses one side cabling mode to be designed, and the main body of antenna assembly 1 is a coil 11, and this line
Circle 11 is one side coiled wire-wound coil, the rectangular helical form of coil 11 cabling.
The two ends of coil 11 are provided with the first feed point 13 for being connected to WPC chip 3, wherein, the first of coil 11 the inner

Outfan, forms WPC charge loop.
Coil 11 is provided with a switch element 12, and coil 11 is divided into two concentric coil gradings 111,112, its
In, coil grading 111 is positioned at the periphery of coil grading 112.Owing to coil 11 is one side coiled wire-wound coil, this two coil grading 111,
In 112 are i.e. generally aligned in the same plane, and direction of winding is identical.When switch element 12 turns on, two coil gradings 111,112 are connected
It is integrally formed；When switch element 12 disconnects, two coil gradings 111,112 are electrically isolated from each other.
Two second feed point 14 for being connected to NFC chip 4 it are respectively provided with on two coil gradings 111,112.Coil grading 111
On two second feed point 14 respectively drawn by a wire jumper 18, the coil grading 111 part between two second feed point 14 is by structure
Become to support the NFC antenna of NFC function.Two second feed point 14 on coil grading 112 are respectively drawn by a wire jumper 19, this coil
The segmentation 112 part between two second feed point 14 also constitutes the NFC antenna supporting NFC function.This two parts NFC antenna is the most also
Connection, and it is electrically connected to NFC chip 4.
The operation principle of this antenna assembly 1 is as follows:
Under antenna assembly 1 works in WPC functional mode, i.e. when WPC chip 3 works, switch element 12 turns on, two coils
Segmentation 111,112 is linked as entirety, and WPC function supported by antenna assembly 1.Now, antenna assembly 1 equivalent circuit diagram as it is shown on figure 3,
Coil 11 between two first feed point 13 constitutes complete closed-loop path by wire jumper 16 and WPC chip 3.NFC function is then passed through
Measure relevant in mobile terminal is isolated, and the second feed point 14 on coil 11 is inoperative.
In the present embodiment, owing to two first feed point 13 lay respectively at outer end end points and the inner end points of coil 11, now,
Whole coil 11 all constitutes the charge coil of WPC.In order to ensure charging current and the charge efficiency of WPC, the sectional area of coil 11
Increasing under conditions of design allows with cabling area, its cabling can use copper cash, FPC (Flexible Printed as far as possible
