Amplification, filtering, and launched by antenna after duplexer；The filtering for the signal that complete twin aerial receives, then into
Enter radio frequency chip module to be demodulated.
Duplexer 50 and antenna tuning module 40 (i.e. antenna adjustments system), to be directed to transmission line structure, pair net
Network, antenna resonating element, antenna and antenna feed be adjusted, i.e., according to carrier wave polymerize Frequency Band Selection match accordingly
Circuit, distributing point and short dot etc. are also the respective antenna structure of each frequency range for having selected carrier wave to polymerize.
Herein, antenna tuning module 40 has multiple input and multiple output ends.Illustrated for emitting link below.It is sending out
It penetrates in link, the multicarrier output of the multiple input end difference respective antenna switch of antenna tuning module, antenna tuning module
Multiple output ends correspond to the multiple distributing points and short dot of multiband antenna respectively.(the ratio when needing to carry out multiple carrier wave polymerizations
As three carrier waves of carrier wave 2, carrier wave 5 and carrier wave L polymerize), each carrier transmission signal is exported from duplexer to antenna tuning module
Afterwards, baseband chip control antenna tuning module selects to be suitble to carrier wave 2, carrier wave 5 according to the frequency of each carrier signal of required transmitting
With the match circuit, distributing point and short dot of carrier wave L etc.；Then each carrier transmission signal is sent via respective feed points to day

Except, in Antenna Design, the distance of other distributing points and possible short dot in each distributing point to radiator, and belong to
The distance of value and ground plane away from radiator of reactance circuit matching network between distributing point and switch is all variable.Pass through
Use multiband antenna so that the antenna is functionally similar to contain the antenna for supporting different frequency bands.
Based on above structure feature, a workflow of terminal is as follows：
On transmitting chain road, modulates baseband signals that radio frequency chip module exports baseband chip to high-frequency carrier signal
On, and the radiofrequency signal for exporting smaller power is filtered and amplifies to radio frequency front-end devices, then reaches duplexer；By
When duplexer, under the control of baseband chip, each carrier signal passes through carrier wave 1 respectively, the ports carrier wave 2 ... carrier wave L export
To antenna tuning module；Baseband chip selects corresponding according to the FREQUENCY CONTROL antenna tuning module of required transmitting signal at this time
With circuit, distributing point and short dot etc.；Then transmitting signal is sent via distributing point to antenna, free space is radiated to, with base station
System carries out wireless communication.
In receives link, the downlink signal that antenna emits the antenna for base station received is sent to antenna tuning module, this
When the information of each frequency range that receives of baseband chip synchronization gain；Baseband chip is according to the frequency of each frequency range received, control
Antenna tuning module selects corresponding match circuit, distributing point and short dot etc., and each frequency band signals are by respectively suitable later
Tuning access enters duplexer, then send again to duplexer, reaches rf chip receiving terminal by receives link, is penetrating
Frequency chip interior carries out down coversion, and demodulation becomes baseband signal, and is sent to baseband chip and carries out information processing.
It should be noted that antenna under different job requirements, can select a short dot by tuning block come
Be connected to ground, can also select be directly connected to, can also between two or more short dot and ground all selection use.
That is, according to the varying environment of Antenna Operation, the short circuit of antenna the access distributing point and suitable position and quantity of suitable position is determined
Point,
Compared with the relevant technologies, an antenna is still only needed here, and need not use multiplexer.By including more feeds
It puts and supports all frequency ranges with multiband antenna, antenna tuning module and the switching of more short dots, eliminating multiplexing
The volume of antenna will not be increased while device.In aspect of performance, the existing scheme using all channel antenna, need to prop up working as
When holding the carrier wave polymerization of multiple frequency ranges, for example there is the Out-of-band rejection when low frequencies in an intermediate frequency, a low frequency, wide frequency antenna
Bad, when harmonic wave is just fallen into midband, antenna can not just provide preferable degree of suppression.But when using multiband antenna
When going to support the two frequency ranges, intermediate-frequency section can individually improve the efficiency in midband and the degree of suppression outside band, low frequency part
Also efficiency and Out-of-band rejection degree in low-frequency band can be improved simultaneously, and the promotion for meaning antenna performance is improved with internal efficiency,
And Out-of-band rejection degree improves the reduction then meaned to other band interferences, to reduce the interference of carrier wave polymerization, optimizes carrier wave
The performance of terminal when polymerization.
Fig. 5 is the work flow diagram of illustrated steps according to an embodiment of the invention, as shown in figure 5, specific real
The mode of applying is：When terminal works are in carrier aggregation mode, it is poly- which frequency range baseband chip determination first will use carry out carrier wave
It closes；Then each frequency range being polymerize according to carrier wave, configuration duplexer, antenna tuning module and the corresponding match circuit of selection,
Distributing point and short dot etc. select the corresponding antenna structure of each frequency range；After the completion of above-mentioned configuration and selection, that is, complete to each
The corresponding antenna structure of frequency range is tuned so that corresponding antenna structure is operated on desired working frequency range；Then, make
Send with the tuned antenna structure of each frequency range/receive signal.
In conclusion the embodiment of the present invention realizes following advantageous effect：
Firstly, since using multiband antenna, it, in this way can be bright so as to save the Diplexer on radio frequency link
