Embodiment is crossed to be described.
Embodiment 1
The utility model embodiment provides a kind of electromagnetic antenna plate.Illustrate that the utility model is real with reference to Fig. 1 to Fig. 7
The electromagnetic antenna plate of example offer is provided.As shown in figure 1, the electromagnetic antenna plate includes：Electromagnetic antenna layer 1, two insulating barriers 2 and interfaces
Plate 3；Electromagnetic antenna layer 1 includes some first coils 11 and some second coils 12 of mutually insulated, and electromagnetic antenna layer 1 is located at two
Between individual insulating barrier 2；Some first coils 11 and some second coils 12 are connected with interface board 3 respectively.
The coil 12 of first coil 11 and second that electromagnetic antenna layer 1 includes can be fixed on two insulating barriers by PUR
On 2, to avoid the coil 12 of first coil 11 and second from being shifted over.
Wherein, as shown in Fig. 2 each first coil 11 includes the first common port lead, the first signal end lead and some
Some circle main lines that the bearing of trend of circle main coil, the first common port lead and the first signal end lead includes with first coil 11
The bearing of trend of circle is vertical.In coiling first coil 11, the first common port lead and the first signal end lead pass through shown in Fig. 3
Coil tool in the middle of support on 90 ° of wrapping post bending, it is vertical with some circle main coils that first coil 11 includes.
As shown in figure 4, each second coil 12 includes the second common port lead, secondary signal end lead and some circle main lines
Circle.
Electromagnetic antenna layer 1 in electromagnetic antenna plate is formed by stacking by the coil 12 of first coil 11 and second of mutually insulated,
Reception antenna and transmitting antenna are used as using the coil 12 of first coil 11 and second.Some circle main coils that first coil 11 includes
Shape and the shape of some circle main coils that includes of the second coil 12 be rectangle.In order to ensure the strong of transceiving electromagnetic signals
Degree, the shape for the main coil that the coil 12 of first coil 11 and second includes must accurately ensure product orientation precision.In order to true
Protect the shape of main coil that the coil 12 of first coil 11 and second includes accurate, the utility model by special coil tool come
The coil 12 of coiling first coil 11 and second, as shown in Fig. 2 the coil tool includes winding frame and wrapping post, the shape of winding frame
Shape be evenly distributed with rectangle, the four edges of winding frame it is spaced apart between many wrapping posts, two neighboring wrapping post.
And also it is evenly distributed with wrapping post on an also support, support inside the winding frame of coil tool.In coiling first coil 11
During with the second coil 12, according to the position and size of each first coil 11 and each second coil 12, by wire in coil
Square coil is wound out on the wrapping post of tool.
In the utility model embodiment, as shown in figure 5, being said by taking two first coils 11 and two the second coils 12 as an example
The arrangement mode of first coil and the second coil in bright the present embodiment, and in order to seem directly perceived, first coil 11 and in Fig. 5
Some circle main coils in two coil 12 are illustrated with thicker single line circle.Fig. 5 is refer to, what first coil 11 included
