Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in further detail.
Referring to illustrated in figures 1 and 2, the utility model embodiment provides a kind of NFC combined antenna for the mobile phone mobile payment, comprise PCB(Printed Circuit Board, printed circuit board (PCB)) coil 1, skeleton 3, coiled wire-wound coil 2, two coils on skeleton 3 connect pad 4 and two antenna ports 5, coiled wire-wound coil 2 adopts copper wire to form by same direction coiling along skeleton 3, and the diameter of copper wire, the number of turn can be determined according to the demand of antenna parameter.The skeleton 3 general bigger ferrite materials of magnetic permeability that adopt are made, and work to support coiled wire-wound coil 2.Skeleton 3 is provided with two coils and connects pad 4, the two ends of PCB coil 1 respectively by coil connect pad 4 and coiled wire-wound coil 2 two ends be connected in parallel, the magnetic line of force direction of coiled wire-wound coil 2 is vertical with the magnetic line of force direction of PCB coil 1, two coils connect pad 4 and respectively extend an antenna port 5, coiled wire-wound coil 2, skeleton 3, two coil connection pads 4 and two antenna port 5 encapsulation are as a whole, are convenient to the welding encapsulation.
The operation principle of the utility model embodiment is elaborated as follows:
Referring to Fig. 3 and shown in Figure 4, the NFC combined antenna is connected with the antenna matching network of the NFC chip module 6 of mobile phone inside by antenna port 5, forms complete NFC module.In real work, produce electric current I on the NFC chip module 6 of mobile phone inside, connect pad 4 through coil after, split into electric current I 1 on the PCB coil 1 and the electric current I 2 on the coiled wire-wound coil 2, if I1 produces the magnetic field B 1 of a horizontal direction, I2 then produces the magnetic field B 2 of a vertical direction.Therefore the signal on the NFC chip module 6 can be launched to two different directions with magnetic field B 2 by magnetic field B 1.In fact the NFC combined antenna can equivalence be two shunt inductances, by adjusting line footpath, winding diameter and the number of turn of PCB coil 1 and coiled wire-wound coil 2, can change the proportionate relationship of electric current I 1 and electric current I 2, thereby change the intensity relation of magnetic field B 1 and magnetic field B 2, concrete enforcement personnel can adjust the intensity in magnetic field on the different directions according to this characteristic.
Referring to shown in Figure 3, application scenarios under the barrier metallization 7 of mobile phone inside is arranged in the NFC combined antenna, barrier metallization 7 can be battery of mobile phone, SIM card seat or TF deck etc., the magnetic field B 1 that electric current I 1 on the PCB coil 1 produces is vertical with barrier metallization 7 planes, be subjected to the shielding of barrier metallization 7, the magnetic field B 1 that PCB coil 1 produces can be weakened greatly, can't normally send signal; And magnetic field B 2 directions and barrier metallization 7 plane parallel that the electric current I 2 on the coiled wire-wound coil 2 produces are subjected to the shielding of barrier metallization 7 hardly, can send signal normally and ensure transmission.
Referring to shown in Figure 4, be arranged in the application scenarios of NFC combined antenna side at the barrier metallization 7 of mobile phone inside, barrier metallization 7 can be battery of mobile phone, SIM card seat or TF deck etc., magnetic field B 1 and magnetic field B 2 all are not subjected to the shielding of barrier metallization 7, so the signal on the NFC chip module 6 of mobile phone inside can be launched to two different directions with magnetic field B 2 by magnetic field B 1.Fig. 3 and Fig. 4 can express the application scenarios of the inner NFC combined antenna of most mobile phones substantially, no matter the NFC combined antenna is under which kind of environment, all can guarantee to have at least the signal on the direction can normal transmission, so the handset compatibility of this NFC combined antenna be better.
