Wherein, when antenna assembly uses PCB printed antenna, antenna pattern can be formed in the main circuit board of electronic equipment
On.That is, the bracket that the part main circuit board of electronic equipment can be used as antenna assembly uses, to carry out antenna pattern
Cabling, and do not have to the cabling that the individual circuit board of in addition setting one carries out antenna pattern.
For convenience of description, it is in a manner of following enterprising walking lines of part main circuit board by antenna pattern in electronic equipment
Example, is described the scheme of the present embodiment.
As shown in Figure 1, in this example using metal fixing as being illustrated for antenna radio frequency minor matters.
In the electronic equipment of the embodiment, the feeding point 1 and radio frequency for antenna assembly are provided on main circuit board 8
Signal wire 2.Wherein, antenna pattern includes the radio-frequency antenna extraction section 10 and radio frequency minor matters 7 in 8 upward wiring of main circuit board.Radio frequency
One end of signal wire 2 is connect with the feeding point 1 of main circuit board 8, and the other end and radio-frequency antenna of rf signal line 2 draw section 10
One end connection, the other end that radio-frequency antenna draws section 10 are electrically connected by sheet metal 4 with metal fixing 5.Radio frequency branch
Wherein one end of section 7 can be electrically connected by sheet metal 4 with metal fixing 5, can also directly draw with radio-frequency antenna
Section 10 links together out, so that radio frequency minor matters 7, metal fixing 5 can be used as two separated from radio-frequency antenna extraction section 10
A minor matters come using.
Radio-frequency antenna is drawn section 10 and is arranged on main circuit board 8, and the work of connection antenna pattern and rf signal line 2 is played
With.In addition, the radio-frequency antenna, which draws section 10 itself, can also play the role of antenna, no longer illustrate herein.Certainly, for
For those skilled in the art, radio-frequency antenna can not also be used to draw section 10, directly by the end of rf signal line 2 and radio frequency
Minor matters 7, metal fixing 5 are electrically connected together.
Wherein, feeding point 1 is used for feed-in radiofrequency signal, this belongs to the common knowledge of those skilled in the art, herein no longer
It illustrates.It further, further include the match circuit 3 being connected electrically between feeding point 1 and antenna pattern.Wherein, radio frequency is believed
One end of number line 2 is connect with feeding point 1, and the other end of rf signal line 2 is connect with one end of match circuit 3, match circuit 3
The other end is drawn section 10 with radio-frequency antenna and is connect.Match circuit 3 is used to adjust the resonance frequency of antenna.Optionally, match circuit 3
It can be π type match circuit or T-type match circuit.
For main circuit board 8 to be fixed in the shell of electronic equipment, which is located at and day metal fixing
In the corresponding empty regions 6 of line apparatus, and metal fixing is not contacted with ground area.
In one example, metal fixing can be screw 5.The material of sheet metal 4 is, for example, copper.When screw 5 screws
Afterwards, the nut of sheet metal 4 and screw 5 is engaged together.In this way, when the nut of 5 end of screw fixes main circuit board 8, energy
Enough and exposed sheet metal 4 comes into full contact with, and radiofrequency signal can be transmitted directly to gold by rf signal line 2 and match circuit 3
Belong to piece 4, and then is transferred in a radio frequency minor matters of the antenna that screw 5 forms and signal radiation is gone out by screw 5.
It should be noted that in a vacuum, 1/4 wavelength of general 5G antenna is 1.5cm, due to practical main circuit board 8
Dielectric constant is bigger than vacuum, along with the influence of track on main circuit board 8 and sheet metal 4 etc., the length of antenna actually debugged
Degree can be shorter than theoretical length.
In practical application, by adjusting the match circuit 3 between screw 5 and feeding point 1, it is in antenna resonance
Between 5150MHz~5850MHz, so that it may realize that screw 5 is used directly as a radio frequency minor matters of 5G antenna.
For the antenna of multiband, then need to adjust the antenna pattern and match circuit 3 of the empty regions 6 of antenna, also
It is to say, is connected to the antenna in empty regions 6 from the radiofrequency signal of feed-in from feeding point 1 by rf signal line 2 and match circuit 3
On pattern, by adjusting match circuit 3, the racemosus section for enabling radiofrequency signal to form to the greatest extent along antenna pattern and screw 5
It is radiate in antenna.In this way, the function of 5G antenna not only may be implemented, the function of other more frequency ranges can also be realized.
In this example, the screw 5 in empty regions 6 is not contacted with ground area or metallic region, in this way, 5 conduct of screw
One radio frequency minor matters of 5G antenna are in use, can have good radiation space, and can save the cost of manufacture of antenna.
Meanwhile in practical applications, it can according to need the length for changing antenna pattern, also can in a disguised form change antenna in this way
The length of one radio frequency minor matters makes antenna resonance in required frequency range.
As shown in Fig. 2, in this example using metal fixing (screw 5) as being said for one of antenna parasitic minor matters
It is bright.
In this example, including feeding point 1, feedback place (view does not provide), rf signal line 2.Wherein, antenna pattern includes posting
Raw minor matters 9 and radio frequency minor matters 11.
One end of rf signal line 2 is connect with the feeding point 1 on main circuit board 8, the other end and radio frequency of rf signal line 2
Minor matters 11 connect.One end of parasitic minor matters 9 is connect with the feedback place (ground terminal) on main circuit board 8, the other end through sheet metal 4 with
Metal fixing electrical connection, so that metal fixing can be used as the extension of parasitic minor matters 9
It further, further include match circuit 3 in antenna assembly shown in Fig. 2.Wherein, one end of rf signal line 2 with
Feeding point 1 connects, and the other end of rf signal line 2 is connect with one end of match circuit 3, the other end and radio frequency of match circuit 3
Minor matters 11 connect.Wherein, match circuit 3 is used to adjust the resonance frequency of antenna.
Wherein, feeding point 1 is used for feed-in radiofrequency signal.Match circuit 3 is used to adjust the resonance frequency of antenna.Optionally,
Match circuit 3 can be π type match circuit or T-type match circuit.
In this example, from the radiofrequency signal of feed-in from feeding point 1, headroom is connected to by rf signal line 2 and match circuit 3
In radio frequency minor matters 11 in region 6, radiofrequency signal is set to radiate to the greatest extent along radio frequency minor matters 11 by adjusting match circuit 3
It goes out.
To increase the bandwidth of a certain frequency range, the parasitism of antenna can be made by the length of cabling in the parasitic minor matters 9 of adjusting
The resonance of minor matters 9 is in this frequency range, to realize the purpose for increasing this band bandwidth.It should be noted that parasitic minor matters 9
It is connected to ground terminal, but parasitic minor matters 9 are not the ground of main circuit board 8 in itself.
Electronic equipment provided in this embodiment makees the metal fixing of the ungrounded setting of empty regions in electronic equipment
For a part of antenna pattern, the empty regions in electronic equipment can be efficiently used, make antenna that there is good radiation space.
