Description
Technical field
The utility model relates to field of antenna, more particularly, to a kind of universal antenna modules.
Background technique
NFC near-field communication is a kind of wireless communication technique of short distance, is capable of providing safety, rapidly wireless communication company
It connects, and can allow to carry out contactless Point-to-Point Data Transmission and data interaction between electronic equipment.NFC technique is wide at present
It is applied on each communication equipment generally.Existing day line access mode is all by antenna by feed point in the market, with smart machine
Mainboard is connected, and the circuit for controlling antenna and matching are all on its mainboard.And different facility environments is needed through debugging antenna ginseng
Matching on several and circuit board is to meet the performance requirement of antenna under circumstances.For in the prior art to environmental requirement
Compare stringent problem, it is urgent to provide a kind of antenna modules that just can be suitably used for various environment using preset parameter matching.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of universal day to overcome the problems of the above-mentioned prior art
Line mould group.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of universal antenna modules, including be from top to bottom successively bonded aerial coil, magnetic separator, sheet metal and
Pcb board, one end of the pcb board are set there are two feed point, which connect with aerial coil, the pcb board it is another
One end is set there are three feed point, one of feed point ground connection, and other two feed point is used to connect with the circuit board of smart machine.
Further, the area of the sheet metal is greater than the area of the surrounded plane of aerial coil.I.e. sheet metal is being just
The orthographic projection of the surrounded plane of aerial coil can be completely covered for projection.
Further, the sheet metal with a thickness of 0.2mm~0.3mm.
Further, the material of the sheet metal is copper or aluminium.
Further, the magnetic separator is plate-like structure, and area is greater than the area of sheet metal.That is magnetic separator
Orthographic projection the orthographic projection of sheet metal can be completely covered, so just but also the effect every magnetic is best.
Further, the magnetic separator with a thickness of 0.1mm~0.3mm.
Further, the magnetic separator is nanocomposite or Ferrite Material.
Compared with prior art, the utility model has the advantage that
1, layer of structure is clearly demarcated, is simply easily assembled, it is only necessary to which two feed points on pcb board are connected to the electricity of smart machine
Road plate, therefore can accomplish plug and play；
2, NFC antenna and sheet metal are fitted in the utility model, external environment can be effectively reduced to antenna performance
Influence, therefore only need to mix up antenna modules performance parameter in advance, it is subsequent without debugging matching, it can be applicable in a variety of set
It is standby；
3, due to not needing to reduce research and development cost according to different machine environment de-regulation antenna performances, also make
The production for obtaining antenna is more convenient.

Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.
Embodiment
Universal antenna modules include the aerial coil 1 being from top to bottom successively bonded, magnetic separator 2, sheet metal 3 and PCB
Plate 4, referring to Fig. 1 and Fig. 2.
One end of the pcb board 4 is set there are two feed point, which connect with aerial coil 1, the pcb board 4
The other end set there are three feed point, one of feed point ground connection, other two feed point with the circuit board of smart machine for connecting.
Referring to Fig. 3.When it is implemented, feed point a 41 and feed point b 42 are connect with antenna, feed point c 43, feed point e 45 and smart machine
Circuit board connection, feed point d 44 are grounded.
The area of sheet metal 3 is greater than the area of the surrounded plane of aerial coil 1, i.e. the orthographic projection of sheet metal 3 can be by antenna
The orthographic projection of the surrounded plane of coil 1 is completely covered, and aerial coil 1 can be made to be attached on sheet metal 3 in this way.Specific real
Shi Shi, the thickness of sheet metal 3 are chosen for 0.2mm~0.3mm, and the material of sheet metal 3 can choose copper or aluminium.
Magnetic separator 2 is plate-like structure, and area is greater than the area of sheet metal 3.I.e. the orthographic projection of magnetic separator 2 can incite somebody to action
The orthographic projection of sheet metal 3 is completely covered, so just but also the effect every magnetic is best.The magnetic separator 2 with a thickness of
0.1mm~0.3mm.The magnetic separator 2 is nanocomposite or Ferrite Material.
Obviously, relevant technical staff in the field can carry out various changes and deformation without departing from this reality to this utility model
With novel spirit and scope.If these modification and variation of the utility model in this way belong to the claim of the utility model
And its in the range of equivalent technologies, then including the utility model is also intended to forgive these changes.
