The covering of state, and exist simultaneously a preferable LTE B39 mode.
Combination two: when switched matching circuit 6 and first switch 7 are connected, and second switch 8 disconnects, slot antenna sheet
The signal cover of body 2 is the second band limits, and specifically, at this moment slot antenna ontology 2 is in the first tuner section 4 to gap day
The resonance of the first end of line ontology 2 can be realized in the first tuner section 4 to the resonance between feeding point 31 to LTE B39 mode
Covering exist simultaneously a preferable LTE B41 mode.
Combination three: when switched matching circuit 6 and second switch 8 are connected, and first switch 7 disconnects, slot antenna sheet
The signal cover of body 2 is third band limits, and specifically, at this moment slot antenna ontology 2 is in the second tuner section 5 to gap day
The resonance of the first end of line ontology 2 can be realized in the second tuner section 5 to the resonance between feeding point 31 to LTE B8 mode
Covering.Wherein, the frequency range that the first band limits, the second band limits and third band limits cover is different.
Wherein, in summary combination one and 2 two kind of switch state, can effectively realize B39 41 interband CA modes
Covering, and traditional switch solution lacks switched matching circuit 6, has lacked the adjustment mode of antenna mode, cannot be considered in terms of
B39 41, there is no B41 when there is B39, there is no B39 when having B41.In addition, said combination mode three is directed to, due to control switch 62
Closure, passive element 61 in parallel (inductance or capacitor) do not work, play the matching effect for B8, improve the spreadability of B8
Energy.
When the conducting of switched matching circuit 6 is described above, the scene that three switch combinations are turned on or off is explained below
When switched matching circuit 6 disconnects, scene that three switch combinations are turned on or off.

The resonance of the first end of line ontology 2 can be realized in the second tuner section 5 to the resonance between feeding point 31 to LTE B5 mode
Covering, since the passive element 61 (inductively or capacitively) in parallel of control switch 62 plays a role, to B5 state play string inductance or
Person's serial capacitors effect, is matched for B12, effectively improves B5 efficiency.Wherein, second switch 8 may include that multi-channel control is opened
It closes, one or more can be connected in multiple control switches, can condition switching loss when multichannel simultaneously turns on.Wherein be worth pointing out be,
Under this combination, using the high frequency multiplication of low frequency modal, i.e., B41 mode is covered using the frequency multiplication mode of B5.
Combination six: when switched matching circuit 6 and second switch 8 disconnect, and first switch 7 is connected, slot antenna sheet
The signal cover of body 2 is the 6th band limits.Specifically, at this moment slot antenna ontology 2 in the first tuner section 4 to gap day
The resonance of the first end of line ontology 2 can be realized in the first tuner section 4 to the resonance between feeding point 31 to LTE B40 mode
Covering, due to the presence of switched matching circuit 6, by matching effect effectively by the mode vectors correlation of optimum radiation body to B40 frequency
Section can greatly improve B40 radiation efficiency, and traditional B40 passes through the switch number (T number) for increasing second switch 8, to adjust
B40 length will lead to the variation of parasitic parameter in this way, so as to cause the reduction of all frequency ranges.It is past in order to be compatible with all frequency range effects
B40 mode can not be effectively covered toward the performance of certain frequency ranges can be sacrificed so as to cause traditional switch antenna.
Combination seven: when switched matching circuit 6, first switch 7 and second switch 8 disconnect, slot antenna ontology 2
Signal cover is the 7th band limits, and at this moment slot antenna ontology 2 is at the first end of feeding point 31 to slot antenna ontology 2
The resonance at end can realize the covering to LTE B12 mode, in the passive element 61 (inductively or capacitively) in parallel of control switch 62
To effect, string inductance or serial capacitors effect are played to B12 state, is matched for B12, effectively improves B12 efficiency.Its
In, the 4th band limits, the 5th band limits, the 6th band limits and the frequency range of the 7th band limits covering are different.
To sum up, the embodiment of the present invention passes through switch by adding a switched matching circuit between feeding point and feed
Be turned on or off with the combination between circuit and first switch and the second switch, realize mutiple antennas frequency range (such as B5,12,39,
40, multiplexing 41 etc.), and the radio-frequency performance of each frequency range is matched, the covering of interband CA under especially compatible different antennae mode.
