Referring to Fig. 2, in the method for adjustment first embodiment of inventive antenna performance, the method for adjustment of the antenna performance is answered
For mobile terminal, the mobile terminal includes: PCB, antenna and microphone, and the microphone includes microphone body and Mike
Wind ontology is in PCB upward wiring；
The method of adjustment of the antenna performance includes:
Step S11 obtains the initial position of antenna, microphone body and cabling with respect to PCB, test initial position antenna
Bandwidth is coupled, and using the coupling bandwidth of initial position antenna as initial coupling bandwidth.
Mobile terminal needs to test after manufacture antenna and receives the corresponding bandwidth of signal, since antenna local environment is complicated,
It is in existing technology that the devices such as antenna and microphone are separate, to ensure that the bandwidth of antenna reception signal meets the need of practical application
Want, but be also possible that allow antenna far from devices such as the electronic devices such as USB joint, microphone, loudspeaker after, what antenna received
Signal cannot still satisfy the use demand, thus propose in the present invention using antenna and microphone body, microphone on PCB
Cabling generates coupling effect, and (coupling effect (Coupling Induction), also referred to as interactive effect, connected effect is in group mind
In, people by interaction affect one another individual two or more in group to join together to generate reinforcement
Phenomenon, referred to as coupling effect, also referred to as interactive effect or connected effect) so that antenna coupling bandwidth (coupling bandwidth:
That is, the beamwidth of antenna that coupling effect generates changes, and corresponding bandwidth under antenna coupling effect) it satisfies the use demand.
Specifically, dispose the position of antenna, microphone body and cabling with respect to PCB as initial first on mobile terminals
Position, antenna, microphone body and cabling can generate coupling effect under initial position, test the strap of antenna under initial position
Width, and the antenna coupling bandwidth that test is got is as initial coupling bandwidth.
Step S12, judges whether initial coupling bandwidth meets preset rules.
Specifically, it is disposed due to antenna, microphone body and cabling opposite with pcb board to be normal, that is, antenna, Mike
Coupling effect can be generated between wind ontology and cabling, but the corresponding coupling bandwidth of coupling effect not necessarily meets antenna performance and wants
(requirement of mobile terminal) is asked, needs to judge whether initial bandwidth meets the regular (preset rules are as follows: according to operator of setting
The demand bandwidth that bandwidth requirement is correspondingly arranged, the transmitting of demand bandwidth and the application market of mobile terminal, different operator's signals
Frequency has relationship, can be configured in the details for determining mobile terminal), that is, initial coupling bandwidth is obtained, and will be first
The coupling bandwidth that begins is compared with demand bandwidth；If initially coupling bandwidth and demand bandwidth match, the initial bandwidth that couples meets
Preset rules, if initially coupling bandwidth and demand bandwidth mismatch, the initial bandwidth that couples does not meet preset rules.
It is opposite to adjust antenna, microphone body and cabling if initially coupling bandwidth does not meet preset rules by step S13
The position of PCB, so that the adjustment coupling bandwidth of adjustment position meets preset rules.
If initially coupling bandwidth does not meet preset rules, that is, initial coupling bandwidth and demand bandwidth mismatch, then adjust day
The position of line, microphone body and cabling with respect to PCB can correspond to one in adjustment antenna, microphone and cabling these three elements
A or multiple element position, so that antenna, microphone and cabling are relative to the adjustment strap for adjusting position on pcb board
Width meets preset rules, in the present invention further include: if initially coupling bandwidth meets the demand bandwidth of mobile terminal, by day

Before the method for adjustment step S10 of performance further include:
Step S21 determines the position of microphone body and antenna, tests the corresponding antenna performance bandwidth of antenna performance, and
By antenna performance bandwidth compared with demand bandwidth.
Specifically, it pays the utmost attention to not utilize coupling effect first before using coupling bandwidth, to after disposing microphone
(that is, after external environment of determining antenna), debugs the performance of antenna, and whether test antenna performance can satisfy demand band
Width, that is, determine the position of microphone body and antenna, and test obtains the corresponding bandwidth of antenna, and the beamwidth of antenna that test is obtained
As antenna performance bandwidth, antenna performance bandwidth is compared with demand bandwidth.
Step S22 fixes the position of microphone body and antenna if antenna performance bandwidth and demand bandwidth match.
If antenna performance bandwidth is with demand bandwidth match, (antenna performance bandwidth refers to demand bandwidth match: antenna performance
Bandwidth is identical as demand bandwidth better than demand bandwidth or antenna performance bandwidth), then fix the position of microphone body and antenna
It sets, that is, not generate coupling effect, antenna performance tests the bandwidth demand that corresponding antenna performance is sufficient for mobile terminal.
Step S23 debugs antenna, if antenna performance bandwidth and demand bandwidth mismatch so that antenna performance
Bandwidth meets preset rules.
If antenna performance bandwidth is mismatched with demand bandwidth, (antenna performance bandwidth refers to demand bandwidth mismatch: antenna
Capability bandwidth is unsatisfactory for demand bandwidth), then antenna is debugged, so that antenna performance bandwidth meets preset rules, specifically,
According to the relationship of antenna performance bandwidth and demand bandwidth, the debugging (debugging of preset times: can be with of preset times is carried out to antenna
It is interpreted as repeatedly debugging, the number of debugging can be carried out automatically controlling by mobile terminal antenna performance test personnel) so that antenna
Capability bandwidth and demand bandwidth match do not need to utilize day if repeatedly debugging aft antenna capability bandwidth and demand bandwidth match
In PCB upward wiring generation coupling effect, the performance of antenna can satisfy demand bandwidth, corresponding for line and microphone body and microphone
The fixed position for meeting antenna when needing bandwidth, microphone body.
If the debugging aft antenna capability bandwidth of preset times and demand bandwidth mismatch, microphone is set and is walked on PCB
Line can also use the different combinations of antenna feed point so as to generate coupling effect between antenna, microphone body and cabling
And the multiple adjustment mode of position is adjusted, measurement antenna couples bandwidth, and corresponding the step of executing step S11 in Fig. 2, with
Antenna is set to couple bandwidth meet demand bandwidth.
In the present embodiment during mobile terminal antenna performance adjustment, it is first determined antenna external condition, in day
After the external condition of line determines, antenna performance is debugged, it is directly solid if antenna performance corresponds to bandwidth meet demand bandwidth
Determine aerial position, if antenna performance is unable to meet demand bandwidth, antenna, microphone body and cabling are set relative to PCB
The position of plate makes it generate coupling effect, and antenna is accordingly made to generate coupling bandwidth, and such method can guarantee mobile terminal
Making the working efficiency of mobile terminal antenna performance test personnel while antenna performance has a degree of promotion；When antenna sheet
Body debugging reach capacity state when, can also pass through modification microphone track lengths, with the spacing and antenna feed point of antenna body
Different combinations and position multiple adjustment mode, integrally to promote antenna radiation performance, and can achieve optimization it is specific
The purpose of frequency point performance.
Further, referring to Fig. 4, during the 3rd embodiment of the method for adjustment of inventive antenna performance provides, the antenna
After the method for adjustment step S12 of performance further include:
Step S31 is adjusted in antenna, microphone body and cabling if initially coupling bandwidth does not meet preset rules
Position of one or more element relative to PCB.
Specifically, if initially coupling bandwidth does not meet preset rules, that is, antenna, microphone body and cabling are relative to PCB
The coupling bandwidth that the initial position of plate generates does not meet demand bandwidth, then needs to adjust initial position, it may be determined that antenna, microphone
Relative to the position of pcb board, adjustment adjustment microphone makes to couple in the length or/and cabling of PCB upward wiring and the spacing of antenna
Bandwidth obtains corresponding adjustment (in conjunction with the track lengths of adjustment 31 in Fig. 8, Fig. 8.Wherein, microphone body 32 and mobile phone PCB connect
It connects sufficiently, and cabling of the microphone 3 on PCB, also to carry out packet ground shielding processing, with antenna reference sufficiently connect.It is logical
