Connection PCB mainboard, switch matching network circuit is provided with the PCB main board, and the switch matching network circuit connects with switch
Access point connects.
Preferably, the switch matching network circuit includes switch control chip, the switch being connected with switch control chip
Path matching body, switch and switch ways microstrip line, by switch access point access switch control chip, then pass through switch ways
Matching body crosses switch ways microstrip line access PCB main board.
Preferably, the switch matching network circuit is arranged on the empty regions of the PCB main board, advantageously ensures that switch
The normal work of matching network circuit.
Preferably, the switch ways matching body is inductively or capacitively, the magnitude range of electric capacity and inductance can be according to reality
Antenna requirements are set, and flexibility is strong.
Preferably, the quantity of the switch ways matching body is at least two, and multiple switch path matching body is set can be with
Cover broader frequency range so that the performance of antenna for mobile phone is more preferable.
Preferably, the switch control chip is connected with switch access point.
Preferably, the switch is single-pole single-throw switch (SPST) or single pole multiple throw.
Preferably, the width of the switch ways microstrip line is more than 0.1mm, and its periphery headroom is more than 1mm, can make tune
It is more excellent to try effect.
Preferably, the antenna body form is PIFA, IFA, LOOP, metal edge frame, narrow frame, three-stage and U-lag
In any one, make antenna optimization have more selections.
Compared with prior art, the beneficial effects of the present invention are：Matching network circuit is switched by setting, is first determined just
Begin the resonance conditions of each path, then switch the setting of each frequency range, is carried out by antenna body main resonance or so frequency deviation
The length of switch ways microstrip line is debugged, without changing the use function of switch, the increase of switch ways microstrip line physical length
So that resonance is deeper, bandwidth is wider, change the limitation of former matching and debugging, and variable connector state is set in the confined space
Broader frequency range can be covered by putting so that the performance of antenna for mobile phone is more preferable, allows antenna prioritization scheme to have more choosings
Select.

Embodiment
In order that those skilled in the art is better understood from technical scheme, below in conjunction with the accompanying drawings to the present invention
Technical scheme be further elaborated.
As Figure 1-3, a kind of handset switch combined antenna, including antenna body 1 and PCB main board 3, the antenna body
1 includes distributing point 5, earth point 6 and switch access point 4, and switch access point 4 is arranged on the centre of antenna to stub area, fed
5 and the connection PCB mainboard 3 of earth point 6 are put, switch matching network circuit 2, the switch pair net are provided with the PCB main board 3
Network circuit 2 is connected with switch access point 4.
Switch 12 is traditional single-pole single-throw(SPST or single pole multiple throw, and switch 12 is adjusted according to common debud mode
Examination, and the length of switch ways microstrip line 13 includes antenna and antenna body 1 forms completed antenna.
Switch matching network circuit 2 is arranged on the empty regions of the PCB main board 3, including switch control chip 7, with opening
Switch ways matching body, switch 12 and switch ways microstrip line 13 that control chip 7 connects are closed, switch ways microstrip line 13
Width is more than 0.1mm, and its periphery headroom is more than 1mm, logical by the access switch control chip 7 of switch access point 4, then by switching
Road matching body crosses switch ways microstrip line 13 and accesses PCB main board 3.
Switch ways matching body is inductively or capacitively, the magnitude range of electric capacity and inductance can set according to actual antennas demand
Put, and its quantity is at least two, multiple switch path matching body, which is set, can cover broader frequency range so that mobile phone day
The performance of line is more preferable.
Switch ways matching body shares four, and first switch path matching body 8, second switch path matching body the 9, the 3rd are opened
Path matching body 10 and the 4th switch ways matching body 11 are closed, the length of individual channel to the switch ways microstrip line 13 on ground differs
Sample, also can be different in the size of individual channel frequency deviation with frequency range, and the length of switch ways microstrip line 13 is led humorous depending on antenna body 1
Left and right frequency deviation shake to be debugged, the change centering high frequency effect of its length becomes apparent from, and we can be by switch during Antenna Operation
Normal principle selects different switching pathways and switch ways matching body, different antenna conditions is debugged, to reach wideband
Effect.
Embodiment：As shown in figure 4, it is contrast optimization 1800mHz-2100mHz resonance figures, wherein switch 12 uses hilted broadsword four
Throw switch, contrast test is carried out by first switch path matching body 8, reset condition only changes first switch path matching body
8 matching value, first switch path matching body 8 here is electric capacity, and its matching value is 3.3pf, now occurs one preferably
Resonance, as shown in lines A, the matching value of first switch path matching body 8 is then remained 0 ohm again, only change first
The physical length and width of switch ways microstrip line 13 corresponding to switch ways matching body, a more preferable resonance can be obtained,
As indicated by line b, the contrast test figure of two states efficiency is as shown in Figure 5,6.
Test result according to Fig. 5 and Fig. 6 can find that the length of debugging switch ways microstrip line 13 is compared with width
Former common switch ways matching body debugging, is deepened in the frequency band resonance to be optimized, and bandwidth broadens, and in 1800mHz-
2100mHz sections, peak efficiencies improve 10% or so, and most of frequency improved efficiency is more than 5%, in 2500mHz-2700mHz sections,
Peak efficiencies improve 5% or so.
It is described above for the preferable embodiment of the present invention, in the case of present inventive concept is not departed from, carry out it is any aobvious and
The deformation and replacement being clear to, belong to protection scope of the present invention.
