Height and size to GSM antenna are had higher requirement, and for GSM antenna, impedance
Join the important obstruction being to stop miniaturization.
To this end, the designer of the present invention is because drawbacks described above, by concentrating on studies and designing, the longest
Phase is engaged in experience and the achievement of related industry for many years, and research design goes out a kind of mobile phone GSM antenna, with gram
Take drawbacks described above.
Summary of the invention
The technical problem to be solved in the present invention is: along with the demand of miniaturization, to the height of GSM antenna and
Size is had higher requirement, and for GSM antenna, impedance matching is the weight stoping miniaturization
Hinder.
For solving the problems referred to above, the invention discloses a kind of mobile phone GSM antenna, comprise a substrate and letter
Number line, it is characterised in that:
The side of this substrate is provided with ground structure, and described ground structure is provided with high frequency earthing portion and the length of L-shaped
Square low frequency grounding parts, is connected between described low frequency grounding parts and high frequency earthing portion and has ground connection feeding portion；
The middle part of described substrate is provided with high frequency radiation body, and one end of this high frequency radiation body is provided with signal feed-in part；
The opposite side of described substrate is provided with low frequency radiation body, and described low frequency radiation body is by a convoluted company of bending
The portion of connecing is connected to described signal feed-in part；It is provided with male part between described low frequency radiation body and high frequency radiation body；
Described holding wire is provided with signal section and grounding parts, and described signal section is fixed on signal feed-in part, described
Grounding parts is fixed on ground connection feeding portion.
Wherein: described connecting portion is the laminated structure being made of metal.
Wherein: described male part is made of metal.
By said structure, the mobile phone GSM antenna of the present invention has the following technical effect that

2, its simple in construction, with low cost, and practicality is more preferable.
The detailed content of the present invention can be obtained by explanation described later and institute's accompanying drawing.
Accompanying drawing explanation
Fig. 1 shows the schematic diagram of mobile phone GSM antenna of the present invention.
Detailed description of the invention
See Fig. 1, it is shown that the mobile phone GSM antenna of the present invention.
Described mobile phone GSM antenna comprises a substrate 1 and holding wire 2, and the side of this substrate 1 is provided with and connects
Ground structure, described ground structure is provided with the high frequency earthing portion 16 of L-shaped and rectangular low frequency grounding parts 17,
It is connected between low frequency grounding parts 17 with high frequency earthing portion 16 and has ground connection feeding portion 18.
The middle part of described substrate 1 is provided with high frequency radiation body 12, and one end of this high frequency radiation body 12 is provided with letter
Number feeding portion 11；The opposite side of described substrate 1 is provided with low frequency radiation body 13, described low frequency radiation body 13
Being connected to described signal feed-in part 11 by a junction 14, wherein, described connecting portion 14 is for bend back
Rotation shape, it is the laminated structure being made of metal, and each of described connecting portion 14 bends width distance and height
Spend and differ, and being provided with, between described low frequency radiation body 13 and high frequency radiation body 12, the coupling that metal is made
Component 15.
Described holding wire 2 is provided with signal section 21 and grounding parts 22, and described signal section 21 is fixed on signal feedback
Entering portion 11, described grounding parts 22 is fixed on ground connection feeding portion 18.
Thus, when signal feed-in part 11 feed-in high frequency electric, this high frequency electric is by signal feed-in part 11
Return again to signal feed-in part 11 toward the flowing of high frequency radiation body 12 surrounding, and high frequency radiation body 12 can be made to connect
High-frequency signal is penetrated in sending and receiving, again when this signal feed-in part 11 feed-in low-frequency current, owing to connecting portion 14 sets
Between low frequency radiation body 13 and signal feed-in part 11, promote this low-frequency current can be from feeding portion 11 toward even
Meet portion 14, the flowing of low frequency radiation body 13 surrounding returns again to signal feed-in part 11, to increase low-frequency current
Travel path so that this low frequency radiation body 13 can receive, launch low frequency signal.Owing to connecting portion 14 sets
There is multiple spacing 141,142,143, electric current can be made discontinuous and produce the coupling of multiple magnetic field, thus carry
High impedance matching effect.
Owing to being provided with male part 15 between this low frequency radiation body 13 and high frequency radiation body 12, thus can avoid
Second electric current 131 of low frequency radiation body 13 offsets toward the direction of high frequency radiation body 12, and can promote low frequency
The impedance of radiant body.
By said structure, the mobile phone GSM antenna of the present invention has the advantage that
1, GSM impedance matching effect is improved, it is ensured that mobile phone signal transmission quality；
2, its simple in construction, with low cost, and practicality is more preferable.
It is readily apparent that above description and record are only to illustrate rather than in order to limit the present invention's
Disclosure, apply or use.Although describing the most in an embodiment and being described in the drawings reality
Execute example, but the present invention be not intended to by accompanying drawing example and be described as in an embodiment it is now recognized that optimal
Pattern is to implement the specific examples of the teachings of the present invention, and the scope of the present invention will include the explanation fallen into above
Book and any embodiment of appended claim.
