The frequency of structure 51 and first antenna structure 51 also close to when, GPS antenna structure 53 can will reduce making for first antenna structure 51
Use efficiency.For example, the coverage area of GPS antenna 53 is 1500-1600MHz, and first antenna structure 51 is in frequency of use intermediate frequency
When segment limit 1710-2700MHz, because of the limitation of complete machine width, because of GPS antenna structure 53 and 51 phase of first antenna structure
Neighbour, at this moment can reduce first antenna structure 51 1710MHz or so efficiency.According to the radiation of the first antenna structure 51 frequency
Section, determines the connection relation of the GPS antenna structure 53 and the radio-frequency module 54.When first antenna structure 51 is switched to intermediate frequency
When so that GPS antenna structure 53 is disconnected with radio-frequency module 54, to reduce GPS antenna structure 53 to main collection antenna structure
Efficiency influences, and puies forward the efficiency of antenna module.
It should be noted that processor 60 and the logic control switch 56 that control switch 56 can be integral type, it can also
It is that processor 60 is provided separately with control switch 56, processor 60 connect to control control switch 56 with control switch 56.
It should be noted that the number of antenna structure is not limited to three, the antenna structure may be four, five or
More.

Match circuit 70 can also use various ways, the present embodiment no longer to go to live in the household of one's in-laws on getting married the concrete mode of match circuit 70 one by one
It states.
Please refer to Fig.1 the flow diagram that 1, Figure 11 is antenna switching method provided by the embodiments of the present application.
The antenna switching method is applied to electronic equipment, and the electronic equipment includes processor 60 and antenna module 50, institute
Antenna module 50 is stated to include first antenna structure 51, the second antenna structure 52, GPS antenna structure 53, radio-frequency module 54, tune and open
55 and control switch 56 are closed, the control switch 56 and the tuning switch 55 are coupled with the processor 60；Wherein, described
First antenna structure 51 close to the GPS antenna structure 53, second antenna structure 52 far from the GPS antenna structure 53,
Collect antenna based on the first antenna structure 51, the second antenna structure 52 is diversity antenna；Radio-frequency module 54 is opened by a control
It closes 56 and is coupled respectively to the first antenna structure 51, the second antenna structure 52 and GPS antenna structure 53；
Processor 60 described in S101 obtains the radiating bands of the first antenna structure 51；
Processor 60 described in S102 controls the GPS antenna structure 53 and the radio-frequency module by the control switch 56
54 connection relation.
It should be noted that switching the radiating bands of first antenna structure 51 by the tuning switch 55, to realize
The radiation of antenna structure full frequency band, full frequency band include low-frequency range (700-960MHz), Mid Frequency (1710-2170MHz) and height
Frequency range (2300-2690MHz) signal.
When the first antenna structure 51 switches to intermediate frequency, the control switch 56 is so that the GPS antenna structure 53
It is disconnected with the radio-frequency module 51.For example, when first antenna structure 51 is transformed into intermediate frequency by low frequency, processor 60 detects
When reaching 1710MHz to the radiating bands of the first antenna structure 51, then so that GPS antenna structure 53 and the radio-frequency module
54 disconnect, or when it is described when first antenna structure 51 by high frequency conversion to intermediate frequency when, processor 60 detects described first
When the radiating bands of antenna structure 51 reach 2170MHz, then so that GPS antenna structure 53 disconnects company with the radio-frequency module 54
Connect, will not thus reduce GPS antenna structure 53 to first antenna structure 51 Mid Frequency radiation efficiency, to provide antenna
The performance of component 50.
When the first antenna structure 51 switches tremendously low frequency or high frequency, the control switch 56 is so that the GPS antenna
Structure 53 is connect with the radio-frequency module 54.
Detailed Jie has been carried out to antenna module 50, electronic equipment and antenna switching method provided by the embodiments of the present application above
It continues, specific examples are used herein to illustrate the principle and implementation manner of the present application, and the explanation of above example is only
It is to be used to help understand the application.Meanwhile for those skilled in the art, according to the thought of the application, in specific embodiment party
There will be changes in formula and application range, in conclusion the contents of this specification should not be construed as limiting the present application.
