To keep the technical problems solved, the adopted technical scheme and the technical effect achieved by the invention clearer, below
It will the technical scheme of the embodiment of the invention will be described in further detail in conjunction with attached drawing, it is clear that described embodiment is only
It is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those skilled in the art exist
Every other embodiment obtained under the premise of creative work is not made, shall fall within the protection scope of the present invention.
Fig. 2A is please referred to, is a kind of antenna system of the antenna switching method provided in the specific embodiment of the invention
Connection schematic diagram, the antenna system are set to terminal, as shown in the figure comprising：
More antennas 11, wireless transceiver 12, reflection feedback device 13 and multi-pole, multi-throw switch 14；The more antennas 11
It is connected respectively with multiple pins of one end of multi-pole, multi-throw switch 14, a pin of the other end of the multi-pole, multi-throw switch 14
It is connected by reflection feedback device 13 with the primary path of wireless transceiver 12, remaining pin diversity with wireless transceiver 12 respectively
Access is connected；The feedback end of the reflection feedback device 13 is connected with the reflection collection terminal of the wireless transceiver 12.
Wireless transceiver 12 is the controlling component that terminal realizes communication, and antenna 11 is connect with wireless transceiver 12, wirelessly
Transceiver 12 controls antenna 11 and sends and receives radiofrequency signal.Standing-wave ratio is for describing standing wave antinode voltage and peak voltage amplitude
The ratio between, also known as standing-wave ratio.When standing-wave ratio is equal to 1, the impedance exact matching of feeder line and antenna 11 is indicated, at this time high-frequency energy
It is all radiate by antenna 11, not the reflection loss of energy；When standing-wave ratio is infinitely great, total reflection is indicated, energy is complete
It does not radiate；Reflection feedback device 13 is i.e. for detecting reflection loss.Multi-pole, multi-throw switch 14 realizes each antenna 11
Switching.In fig. 2,2 antennas 11 are only set, more antennas 11 can be set according to the actual demand of terminal, it is specific to switch
Process is identical.In fig. 2, FBRX indicates the physical path for receiving the testing result of reflection feedback device 13, is wirelessly receiving
It sends out in device 12, FBRX is accessed by reflection collection terminal, TRX indicates that primary path, DRX indicate diversity access, determine in other attached drawings
Justice is identical.
On the basis of above-mentioned antenna system, the method for further realizing antenna switching, as shown in Figure 2 B, this method packet
It includes：
Step S11：Wireless transceiver issues wireless transmission signal to current antenna by primary path, and passes through reflection acquisition
End receives the feedback result of reflection feedback device.
The process of wireless communication realizes that wireless signal is also derived from the electric current along conductor propagation by wireless signal；Electricity
Subsignal reaches antenna 11 from transmitter, and then antenna 11 is obtained using electronic signal as a series of electromagnetic radiations into air
To wireless signal.Signal is by air borne, until it reaches target position.The wireless transmission signal of one terminal is another
The wireless reception of signals of one terminal.For electronic signal during reaching antenna 11 from transmitter, electronic signal may be due to
The reasons such as structure, material, external environment lossless cannot launch, and can generate no line reflection signal at this time.In the present solution, nothing
Line reflection signal can be sent to the reflection collection terminal of wireless transceiver 12 by the feedback end of reflection feedback device 13, by wirelessly receiving
Hair device 12 further judges the result fed back.

Power without line reflection signal.Several simple corresponding relationships, standing-wave ratio 1.0,2.0,3.0,4.0,5.0,7.0,10,1520
When, reflectivity is respectively 0.00%, 11.11%, 25.00%, 36.00%, 44.44%, 6.25%, 66.94%, 76.56%,
81.86%.Specific calculating process belongs to general scheme, does not elaborate herein.
Step S13：When the standing-wave ratio of current antenna is higher than preset threshold value, antenna is switched by multi-pole, multi-throw switch,
Successively calculate the standing-wave ratio of remaining antenna.
If current antenna can ensure signal quality, that is, the standing-wave ratio of current antenna can be in the aspiration level of position
Communication service, even if there may be the better antennas 11 of signal quality than current antenna, without switching.
Only it is higher than preset threshold value in the standing-wave ratio of current antenna, when having influenced communication service, just passes through multitool
Multithrow switch 14 switches antenna 11, and each antenna 11 is sequentially ingressed into primary path, respectively calculates standing-wave ratio, specific calculating process
It is identical as the calculating process in step S12.
Step S14：The minimum antenna of standing-wave ratio is adjusted to current antenna by multi-pole, multi-throw switch.
The minimum antenna 11 of standing-wave ratio illustrates that reflectivity is minimum, has best signal emission results, is adjusted to work as
Preceding antenna.
Next this programme is illustrated in conjunction with actual handoff procedure, specifically please refers to Fig. 2 C and Fig. 2 D.Figure
2C and Fig. 2 D can be considered as the state change of Fig. 2A, and in fig. 2, all antennas 11 disconnect.Fig. 2 C is please referred to, it is false
If reflection feedback can be passed through at this time when the antenna 11 of front upper place is connected as current antenna with the primary path of wireless transceiver 12
Device 13 detects the connection status of current antenna, i.e. standing-wave ratio.If the standing-wave ratio of current antenna is lower than preset threshold value, can
Desired communication instruction is obtained, multi-pole, multi-throw switch 14 keeps current connection state.Otherwise, multi-pole, multi-throw switch 14 is adjusted
So that the antenna 11 of lower section is connected as current antenna, such as Fig. 2 D institute of connection status at this time with the primary path of wireless transceiver 12
Show.As the detection process of the antenna 11 of top, the standing-wave ratio of the antenna 11 of lower section is obtained, to the standing-wave ratio of two antennas 11
Judged, regard the minimum antenna 11 of standing-wave ratio as current antenna.That is, if the standing-wave ratio of the antenna 11 of lower section is low
In the standing-wave ratio of the antenna 11 of top, the connection status in Fig. 2 D is saved；Otherwise the connection shape in Fig. 2 C is also switched back into
State.
In conclusion the primary path in the wireless transceiver 12 of terminal connects reflection feedback device 13, reflection feedback device
13 will emit the corresponding reflection signal feedback generated of signal to wireless transceiver 12, be calculated according to reflection signal and transmitting signal
The standing-wave ratio for emitting signal, when standing-wave ratio increases to a certain extent, by multi-pole, multi-throw switch 14 successively by each antenna 11
Primary path is accessed, the standing-wave ratio of all antennas 11 is detected, the minimum antenna 11 of standing-wave ratio is switched to current antenna, avoids letter
The unordered switching of antenna 11, improves the stability of 11 function of antenna when number intensity is low.
