Embodiment
The present invention is described in further detail below by specific embodiment and with reference to accompanying drawing.
As Figure 1-3, the embodiments of the invention provide a kind of antenna, the antenna can apply in mobile terminal, should
Antenna has the first distributing point 10 and the second distributing point 11 being connected, and this antenna can specifically include the (Printed of pcb board 20
Circuit Board, printed circuit board), metal edge frame 21, the first branch switch 22, the second branch switch 23 and master switch 24.
Pcb board 20 can provide energy for antenna, so that antenna realizes the radiation function of itself.Metal edge frame 21 can be specifically mobile
The center of terminal, it has the clearance zone 12 for being used for setting antenna between pcb board 20, and has adjacent set on metal edge frame 21
The first breaking joint 211 and the second breaking joint 212 put, both can completely cut off the output of energy, and then ensure the radiance of antenna.The
One breaking joint 211 and the second breaking joint 212 can be opened in the bottom of metal edge frame 21.It is located at the first breaking joint on metal edge frame 21
211 and the second part between breaking joint 212 form radiant body, the first distributing point 10 and the second distributing point 11 connect with the radiant body
Connect.
The first electrical communication path, the second distributing point 11 and pcb board 20 are formed between above-mentioned first distributing point 10 and pcb board 20
Between form the second electrical communication path, the first electrical communication path and the second electrical communication path constitute individually enter in whole antenna
The radiation path of the transmitting-receiving work of row signal.First branch switch 22 is series on the first electrical communication path, the second branch switch
23 are series on the second electrical communication path, and master switch 24 is series at the first branch switch 22 and pcb board 20, the second branch switch 23
Between pcb board 20.After being arranged such, the first branch switch 22, the second branch switch 23 and master switch 24 can just control
The break-make of one electrical communication path and the second electrical communication path, to switch the work shape of the first distributing point 10 and the second distributing point 11
State.
Specifically, when master switch 24 be in the first electrical communication path of connection, the first branch switch 22 it is in the conduction state when,
First electrical communication path is in the conduction state, and now the first distributing point 10 works；Accordingly, when master switch 24 is in connection second
When electrical communication path, the second branch switch 23 are in the conduction state, the second electrical communication path is in the conduction state, now the second feedback
Electricity point 11 works.Accordingly, the first branch switch 22, the second branch switch 23 and master switch 24 can be controlled so that whole antenna
Worked in the first distributing point 10, the second distributing point 11 does not work, or the first distributing point 10 does not work, the work of the second distributing point 11
Make, either the first distributing point 10 and the second distributing point 11 work or the first distributing point 10 and the second distributing point 11 not work
The state of work.
After said structure, it is possible to control the shape of the first branch switch 22, the second branch switch 23 and master switch 24
State, realization is only used as signal output part by the first distributing point 10 or the second distributing point 11.When mobile terminal runs into hand-held influence
During problem, it is possible to control the signal output part of antenna away from human hand, that is, that farther distributing point of chosen distance human hand
Work, reduces the hand-held influence to electric wire performance, so that the performance of antenna is more excellent with this.
In addition, above-mentioned antenna controls first using the first branch switch 22, the second branch switch 23 and master switch 24 simultaneously
The state of electrical communication path and the second electrical communication path, can not only improve reliability during switching electrical communication path, additionally it is possible to
Effectively shorten the length of electrical communication path so that the frequency of antenna preferably meets requirement.
In specific embodiment, the quantity of above-mentioned master switch 24 can be selected flexibly, generally can be by the quantity of the master switch 24
One is set to, the master switch 24 can connect with the first branch switch 22, the second branch switch 23 simultaneously.It is described herein
" master switch 24 can be connected with the first branch switch 22, the second branch switch 23 " be referred to simultaneously when being connected master switch 24 with
There is connection bus, one end of the connection bus is connected with master switch 24 between first branch switch 22, the second branch switch 23,
The other end separates Liang Ge branches, and the first branch switch 22 and the second branch switch 23 are connected respectively, is not to say that master switch 24 must
There must be the state for connecting the first branch switch 22 and the second branch switch 23 simultaneously.This structure only by a master switch 24 just
Foregoing technique effect can be realized, therefore the amount of parts of antenna can be reduced, and then reduces the space that antenna takes.
With reference to Fig. 4, it is preferable that at least one of the first branch switch 22, the second branch switch 23 and master switch 24 are
Single-pole double-throw switch (SPDT).When three is disposed as single-pole double-throw switch (SPDT), two working conditions of master switch 24 are respectively：With first
Branch switch 22 is connected, connected with the second branch switch 23, and two working conditions of the first branch switch 22 are respectively：Connection the
One electrical communication path, the first electrical communication path of cut-out, two working conditions of the second branch switch 23 are respectively：The electricity of connection second
Access path, the second electrical communication path of cut-out.
During specific design, the position of the first distributing point 10 and the second distributing point 11 can be obtained by measurement, a kind of preferred
In embodiment, the direction interval of the first distributing point 10 and the second distributing point 11 along the bottom parallel to metal edge frame 21 can be made
Distribution.This measure can be carried out after the rational position of the first distributing point 10 and the second distributing point 11 is measured, by presenting first
Make fine setting in position after electricity point 10 and the second distributing point 11 are measured so that both position relationships meet aforementioned claim,
The radiance of the first distributing point 10 and the second distributing point 11 can suitably be improved by so setting, and then lift the property of whole antenna
Energy.
Further, antenna provided in an embodiment of the present invention can be symmetrical structure, and the line of symmetry of antenna is the first feedback
The center line of line between electricity point 10 and the second distributing point 11.First, this structure can simplify the structure of antenna so that antenna
Processing technology tend to simplify；Secondly, antenna is set to after symmetrical structure, frequency range of antenna etc. when the first distributing point 10 works
The parameter such as frequency range of antenna tends to be identical when parameter works with the second distributing point 11 so that no matter the first distributing point 10 works, also
It is that the second distributing point 11 works, the performance of whole antenna is basically identical, so as to improve the performance of antenna to a greater degree.
