Rate is 102～104 ohm/meter, little in the loss of 100kHz～the radio frequency band of 10 megahertzs, is used in wireless more
Electric aerial coil, radio intermediate-frequency transformer.The feature of soft magnetic ferrite is: saturation flux density is low, magnetic conductance
Rate is low, and Curie temperature is low, and medium-high frequency loss is low, low cost.First three is low is its shortcoming, limits making of it
By scope, the most make great efforts to improve.Latter two is low is its advantage, is conducive to entering high frequency market, the most just
Making great efforts extension.
For getting rid of the interference of electromagnetic wave, the present invention utilizes this soft magnetic ferrite at ordinary times without magnetic force, by outside
If giving magnetic field, magnetic flux can gather together the performance of then electromagnetic wave absorption, manufactures antenna, utilizes soft magnet
Oxysome improves the effect of the performance of antenna.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and provide a kind of at soft magnet oxygen
The method directly manufacturing antenna on body.
The purpose of the present invention can be achieved through the following technical solutions: one directly manufactures sky on soft magnetic ferrite
The method of line, it is characterised in that the method is directly to arrange antenna on soft magnetic ferrite, will be provided with the soft of antenna

Compared with prior art, the present invention is to arrange antenna on soft magnetic ferrite layer, by antenna function with cover electricity
The function of magnetic wave combines, thus is excluded by the electromagnetic wave on antenna, improves the performance of antenna, and
The position variation of antenna can be made.Such as, in present antenna for mobile phone manufacture method, it is usually and antenna is set
Put on the plastic casing of mobile phone, but this plastic shell surface out-of-flatness, and have certain hardness, antenna installation difficulty
Greatly, and production efficiency is low, uses the inventive method, and arranging antenna on soft magnetic ferrite layer has two big advantages:
The first, soft magnetic ferrite layer is plane, and soft, and simple at printed thereon or stickup antenna, forming can
A sheet of disposably to print or to paste, cut the most as required, batch production, production efficiency can be realized
Improve more than 10 times.
The second, can make the position variation of antenna, due to the interference of electromagnetic wave of worrying, existing antenna arranges position
Limited, typically can only manufacture antenna on the plastic casing of mobile phone, even if using the inventive method just electromagnetic wave to be occurred
The place in source, it is also possible to antenna is set.Particularly in antenna manufacturing process in-FPCB manufacturing process, use model
Enclosing can be diversified, as long as occurring direction to start at the reverse side of soft magnetic ferrite from electromagnetic wave form antenna pattern, just
Antenna performance can be improved with electromagnetic wave shielding.
3rd, the thickness of antenna can be reduced, thus reduce the thickness of product.
It addition, the ink of enhancing adhesive force of the present invention is also one of characteristic of the present invention, because, existing
The conductive ink used in antenna manufacturing process is to cooperate with the material PC, PC/ABS of electronic devices and components such as mobile phone
Or the such material of ABS is fabricated by, even if so, conductive ink is still deposited after being printed in mobile phone shell
Bond insecure at antenna with metal or plastics frame, drop to cause on pcb board the risk of short circuit, particularly
Diversified failtests is also done, so the adhesive force of antenna must be very well in mobile phone.Further, soft magnetism
Ferritic material is to be mixed into the multiple mixture such as manganese, zinc in ferrum oxide, the pottery sintered under about 900 degree
Porcelain composition, the attachment of general conductive ink is not all right, it addition, conductive ink traditional on protective layer adheres to the most not
OK, therefore, use the ink of enhancing adhesive force of the present invention, conductive ink firmly can be sticked at soft magnetism
On ferrite layer, safe and reliable.
