Abstract
The utility model discloses a kind of aerial coils based on wireless radio-frequency; including a substrate; substrate is connected with high frequency antenna; high frequency antenna is divided into two strands, and per share to wind in the shape of a spiral, high frequency antenna is lamination layer structure; it is followed successively by conducting wire, PET insulators, electromagnetic shield and armouring guard cover from inside to outside; there is the conductive coil graph layer that there is printing to be formed on substrate the coat of metal, conductive coil graph layer to be electrically connected with high frequency antenna on conductive coil graph layer.The advantageous effects of the utility model are：The noise suffered by aerial coil can be greatly reduced, even if the size of aerial coil becomes smaller, it can also ensure that and adequately check sensitivity, each component of the check device other than the aerial coils such as composition electronic circuit can be made to minimize, required cost is lower, more competitive advantage.
Description
Technical field
The utility model is related to a kind of aerial coil more particularly to a kind of aerial coils based on wireless radio-frequency.
Background technology
The aerial coil of the prior art is acceptant when receiving signal to arrive various noises, although has in the prior art various
Noise reducing apparatus, but it is just difficult to miniaturization using these noise reducing apparatus aft antenna coils, cost can greatly promote.
Utility model content
The purpose of this utility model is to provide a kind of aerial coils based on wireless radio-frequency, solve the prior art and deposit
Shortcoming.
The utility model adopts the following technical solution realizes：
A kind of aerial coil based on wireless radio-frequency, which is characterized in that including a substrate, the substrate and high frequency
Antenna is connected, and the high frequency antenna is divided into two strands, and per share to wind in the shape of a spiral, the high frequency antenna is lamination layer structure, by interior
It is followed successively by conducting wire, PET insulators, electromagnetic shield and armouring guard cover outward, on the substrate there is printing to be formed
Conductive coil graph layer has the coat of metal, conductive coil graph layer and high frequency antenna electricity on the conductive coil graph layer
Gas connects.
Further, the substrate is polyethylene terephthalate film piece.
The advantageous effects of the utility model are：The noise suffered by aerial coil can be greatly reduced, even if day
The size of line coil becomes smaller, and can also ensure that and adequately checks sensitivity, can make other than the aerial coils such as composition electronic circuit
Check device each component miniaturization, required cost is lower, more competitive advantage.
Description of the drawings
Fig. 1 is that the basis of aerial coil constitutes schematic diagram.
Fig. 2 is the lamination layer structure schematic diagram of high frequency antenna.
Fig. 3 is the diagrammatic cross-section of substrate.
Fig. 4 is the schematic top plan view for including substrate and conductive coil graph layer.
Specific implementation mode
By the following description of the embodiment, public understanding the utility model will more be contributed to, but can't should
Specific embodiment given by applicant is considered as the limitation to technical solutions of the utility model, it is any special to component or technology
The definition of sign be changed and/or to overall structure make form and immaterial convert the technology of the utility model of being regarded as
Protection domain defined by scheme.
Aerial coil 1 based on wireless radio-frequency as shown in the figure, including a substrate 2, substrate 2 and high frequency antenna 3
It is connected, it is two strands that high frequency antenna 3, which is divided to, per share to wind in the shape of a spiral, and high frequency antenna 3 is lamination layer structure 4, by the notch in figure
9 as can be seen that lamination layer structure 4 is followed successively by conducting wire 5, PET insulators 6, electromagnetic shield 7 and armouring protection covering from inside to outside
Object 8, the conductive coil graph layer that there is on substrate printing to be formed, has the coat of metal, conductor wire on conductive coil graph layer
It encloses graph layer to be electrically connected with high frequency antenna, substrate is polyethylene terephthalate film piece.
Certainly, the utility model can also have other various embodiments, without departing substantially from the spirit of the present invention and its essence
In the case of, those skilled in the art can make various corresponding change and deformations, but this according to the utility model
A little corresponding change and deformations should all belong to the protection domain of the utility model the attached claims.
