Abstract
The invention relates to an antenna. The antenna comprises an insulating substrate and an antenna pattern. The substrate is provided with an inner surface and an outer surface opposite to each other. The antenna pattern is arranged on the inner surface. The antenna further comprises a sheet pasted to the outer surface, the sheet is made of ferrite materials which have the high resistance rate and the high permeability, and when the antenna is close to a metal object, the sheet is located between the antenna pattern and the metal object, and electromagnetic waves reflected by the metal object can be effectively dredged.
Description
Technical field
The present invention relates to a kind of antenna.
Background technology
Full frequency band concealed antenna (Full Band Internal Antenna) in mobile device (mobile phone, flat board or notebook computer etc.) is when near metal object, and the electromagnetic wave of metal object reflection probably can cause the radiation efficiency of antenna to drop to and cannot use.
So, be necessary above-mentioned technical problem to improve.
Summary of the invention
The object of the present invention is to provide a kind of antenna that improves radiation efficiency that has.
For realizing aforementioned object, the present invention adopts following technical scheme: a kind of antenna, it comprises insulated substrate and antenna pattern, described substrate has relative inside and outside surface, antenna pattern is arranged in inner surface, described antenna also comprises the thin slice that is fitted in outer surface, and described thin slice is that Ferrite Material is made.
Antenna of the present invention comprises the thin slice that is fitted in outer surface, described thin slice is that Ferrite Material is made, Ferrite Material has high resistivity and high magnetic permeability, when antenna is near metal object, sheet metal is between antenna pattern and metal object, can effectively dredge the electromagnetic wave that metal object reflects, electromagnetic wave energy is converted into the energy (being mainly heat energy) of other form and is consumed, reduced the interference of metal object to the radiation efficiency of antenna, make the radiation efficiency of antenna keep stable, ensure antenna reliability service.
Accompanying drawing explanation
Fig. 1 is that antenna of the present invention is near the schematic diagram of metal object.
Embodiment
Refer to Fig. 1, antenna 10 of the present invention comprises an insulated substrate 11, antenna pattern 12 and a thin slice 13, substrate 11 is printed circuit board (PCB), pottery, plastic cement or glass etc., substrate 11 has relative inside and outside surface, antenna pattern 12 is arranged on inner surface, thin slice 13 is fitted in outer surface, is oppositely arranged with antenna pattern 12, and the length of thin slice 13 and width are more than or equal to antenna pattern 12.
Thin slice 13 is made by Ferrite Material, according to required magnetic permeability, select, Ferrite Material has high resistivity and high magnetic permeability, when antenna 10 is near metal object 20, thin slice 13 is between antenna pattern 12 and metal object 20, can effectively dredge the electromagnetic wave that metal object 20 reflects, electromagnetic wave energy is converted into the energy (being mainly heat energy) of other form and is consumed, reduced the interference of the radiation efficiency of 20 pairs of antennas 10 of metal object, make the radiation efficiency of antenna 10 keep stable, ensure antenna 10 reliability services.
Although be example object, the preferred embodiment of the present invention is disclosed, but those of ordinary skill in the art will recognize, in the situation that not departing from by the disclosed scope and spirit of the present invention of appending claims, various improvement, increase and replacement are possible.
