Fig. 2 is another surface view of near-field communication device of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further elaborated:
As shown in Figure 1, near-field communication device 1 includes NFC antenna 11 and circuit board 12, one surface of circuit board 12 is provided with the first clearance zone 121a, this first clearance zone 121a is from the surface indentation of circuit board 12, being provided with the frequency range module 122 being connected with NFC antenna 11 in clearance zone 12, this frequency range module 122 is the conducting wire being arranged in clearance zone 12.
Specifically, this NFC antenna 11 is chip type NFC antenna 11, substantially in rectangular shape, NFC antenna 11 is provided with coil, for transmitting/receiving signal.As the preferred scheme of one, NFC antenna 11 is substantially in rectangular shape, and its length is 3.2mm, and width is 1.6mm, height range for 0.2-0.4mm.
When NFC antenna 11 is assembled on circuit board 12, being positioned at the first clearance zone 121a of circuit board 12, this NFC antenna 11 is formed with frequency range module 122 and electrically connects, and frequency range module 122 controls NFC antenna 11 and launches/receive the signal of near-field communication.In the present embodiment, frequency range module 122 is wire coil.
Being additionally provided with ground hole 123 on circuit board 12, ground hole 123 is positioned at around the first clearance zone 121a.Having earth lead in ground hole 123, this ground connection is arranged, and the circuit on circuit board 12 can be connected with the earth lead of this ground hole 123 thus ground connection.Owing to the earth lead of ground hole 123 is positioned at around the first clearance zone 121a, therefore, when the magnetic field that the earth lead of ground hole 123 is subject to NFC antenna 11 and frequency range module 122 generation affects, it may occur that magnetized phenomenon, thus increasing the magnetic flux of this near-field communication device 1.
As in figure 2 it is shown, in the present embodiment, another surface of circuit board 12 is provided with the second clearance zone 121b, is again provided with frequency range module 122 in the second clearance zone 121b.Having a connection member 124 and a through hole on circuit board 12, this connection member 124 runs through this circuit board 12 by the through hole on circuit board 12.Frequency range module 122 in two clearance zone forms electrical connection by this connection member 124.By above-mentioned setting, the length of frequency range module 122 (wire coil) can be increased, thus increasing the magnetic flux of near-field communication device 1.
