Description
Technical Field
The application belongs to the technical field of communication, and particularly relates to an antenna tuning method and electronic equipment.
Background
Specific absorption rate (Specific Absorption Rate, SAR) is a parameter that measures the impact of thermal energy generated by electromagnetic waves in electronic devices on the human body, and it is critical that the SAR value be kept under standard. In a concurrent scenario of an electronic device, i.e. a scenario in which multiple frequency bands of an antenna transmit signals simultaneously, the SAR value of the antenna may increase.
In the related art, the increase of the SAR value is generally controlled by reducing the maximum conduction power of the concurrent segment, however, the maximum conduction power also needs to meet the 3GPP standard and the authentication requirement, and therefore, the SAR value in the concurrent scenario still has a risk of exceeding the preset standard value.

Detailed Description
Technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of the protection of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The antenna tuning method provided by the embodiment of the application is described in detail below by means of specific embodiments and application scenarios thereof with reference to the accompanying drawings.
The implementation main body of the antenna tuning method provided in the embodiment of the present application may be an electronic device or a functional module or a functional entity capable of implementing the antenna tuning method in the electronic device, where the electronic device in the embodiment of the present application includes, but is not limited to, a mobile phone, a tablet computer, a camera, a wearable device, and the like, and the antenna tuning method provided in the embodiment of the present application is described below by taking the electronic device as an implementation main body as an example.
As shown in fig. 1, an embodiment of the present application provides an antenna tuning method, which may include steps 101-103:
step 101, under the condition that an antenna is in a multi-band concurrency scene, the electronic equipment detects concurrency antenna power of the antenna.
Optionally, the multi-band concurrency scenario may be a 4g+5g concurrency scenario existing in Non-independent Networking (NSA) mode of the fifth generation mobile communication technology (5th generation mobile networks,5G); the method can also be a same-mode multi-band concurrent scene existing in an uplink carrier aggregation (Carrier Aggregation, CA) mode, such as a 4G+WIFI concurrent scene or a 5G+WIFI concurrent scene existing in a mobile hotspot.
Since signals are simultaneously transmitted in a plurality of frequency bands in a multi-band concurrency scene, the SAR value of an antenna in an electronic device may increase. Since the SAR value is positively correlated with the antenna power, the change in SAR value can be determined by detecting the concurrent antenna power of the antenna.
It should be noted that, the electronic device may detect the concurrent antenna power of the antenna under the condition that the antenna tuning parameter of the antenna is a first parameter, where the first parameter may ensure the antenna equalization performance of the concurrent frequency band combination.
Step 102, under the condition that the power of the concurrent antenna is larger than a preset power, the electronic device respectively determines SAR influence values of each frequency band on the antenna.
Optionally, the antenna in the electronic device may include a first frequency band and a second frequency band, and the preset power may include at least one of the following: the antenna comprises first power and second power, wherein the first power is antenna power corresponding to the first frequency band under the condition that the concurrent SAR value of the antenna is the maximum SAR value; and the second power is the antenna power corresponding to the second frequency band under the condition that the concurrent SAR value of the antenna is the maximum SAR value.
In an exemplary embodiment, when the preset power includes a first power and a second power, the electronic device may compare the concurrent antenna power with the first power and the second power, and if the concurrent antenna power is greater than the first power and the second power, determine a SAR influence value of the first frequency band on the antenna and a SAR influence value of the second frequency band on the antenna, respectively.
It should be noted that, since the conduction power and the SAR value are in a positive correlation, the electronic device may determine the first power and the second power at the maximum SAR value by adjusting the conduction power. The maximum SAR value refers to a maximum value that satisfies the SAR detection criteria.
Optionally, the electronic device determines the SAR influence value of each frequency band on the antenna, which specifically may include: the electronic equipment can determine SAR influence values of each frequency band on the antenna according to the frequency of the frequency band; wherein, the SAR influence value of the frequency band with high frequency is larger than the SAR influence value of the frequency band with low frequency.
It should be noted that, the above SAR influence value is used to indicate the influence degree of one frequency band on the SAR value of the antenna.
Based on the scheme, the SAR influence value of each frequency band on the antenna can be determined according to the frequency of the frequency band, so that the influence of each frequency band on the SAR value of the antenna can be determined, and a basis is provided for adjusting the antenna tuning parameters of the antenna.
Optionally, the electronic device may keep the antenna tuning parameters of the antenna unchanged in a case where the concurrent antenna power is less than or equal to the preset power.
Specifically, the concurrent antenna power being smaller than or equal to the preset power indicates that the SAR value of the antenna does not exceed the SAR detection standard, so the electronic device may keep the antenna tuning parameter of the antenna unchanged as the first parameter.
Based on the scheme, under the condition that the power of the concurrent antenna is smaller than or equal to the preset power, the electronic equipment can keep the antenna tuning parameters of the antenna unchanged, so that the electronic equipment can flexibly select whether to adjust the antenna tuning parameters or not, and the antenna is always in a normal running state.
Step 103, the electronic device adjusts the antenna tuning parameters of the antenna according to the SAR influence value, so that the SAR reduction value of the frequency band with the larger SAR influence value is larger than the SAR increase value of the frequency band with the smaller SAR influence value.
Alternatively, the electronic device may control the antenna tuning parameters to bias towards a frequency band where the SAR impact value is small. Thereby, the antenna power of the frequency band with smaller SAR influence value is increased, and the antenna power of the frequency band with larger SAR influence value is reduced.
Specifically, under the condition that the SAR influence value of the first frequency band is larger than the SAR influence value of the second frequency band, the electronic equipment can adjust the antenna tuning parameter of the antenna from a first parameter to a second parameter, wherein the SAR reduction value of the first frequency band is larger than the SAR increase value of the second frequency band; under the condition that the SAR influence value of the first frequency band is smaller than the SAR influence value of the second frequency band, the electronic equipment can adjust the antenna tuning parameter of the antenna from the first parameter to a third parameter, and the SAR increase value of the first frequency band is smaller than the SAR decrease value of the second frequency band.
Illustratively, as shown in table 1, the SAR influence value of the first frequency band is smaller than the SAR influence value of the second frequency band. Before adjusting the tuning parameters of the antenna, the SAR value of the first frequency band is 0.3, the SAR value of the second frequency band is 0.8, and the concurrent SAR value of the antenna is 1.1; after adjusting the tuning parameters of the antenna, the SAR value of the first frequency band is 0.4, the SAR value of the second frequency band is 0.5, and the concurrent SAR value of the antenna is 0.9. That is, although the SAR value of the first frequency band increases after the tuning parameter of the antenna is adjusted, since the SAR influence value of the first frequency band is smaller than the SAR influence value of the second frequency band, the concurrent SAR of the antenna is still reduced after the SAR value of the second frequency band is reduced.
TABLE 1
| First band SAR value | Second band SAR value | Concurrent SAR values | |
| Before adjustment | 0.3 | 0.8 | 1.1 |
| After adjustment | 0.4 | 0.5 | 0.9 |
Based on the above scheme, the SAR reduction value of the first frequency band can be larger than the SAR increase value of the second frequency band under the condition that the SAR influence value of the first frequency band is larger than the SAR influence value of the second frequency band; or under the condition that the SAR influence value of the first frequency band is smaller than the SAR influence value of the second frequency band, the SAR increase value of the first frequency band is smaller than the SAR decrease value of the second frequency band, so that the concurrent SAR value of the antenna can be ensured to be decreased, and the purpose of decreasing the SAR value of the antenna is achieved.
In the embodiment of the application, since the concurrent antenna power and the SAR value of the antenna are in a positive correlation relationship, in a multi-band concurrency scene, if the concurrent antenna power of the antenna is larger than the preset power, the SAR value of the antenna needs to be reduced by taking measures.

Optionally, the preset power includes at least one of: the antenna comprises first power and second power, wherein the first power is antenna power corresponding to the first frequency band under the condition that the concurrent SAR value of the antenna is the maximum SAR value; and the second power is the antenna power corresponding to the second frequency band under the condition that the concurrent SAR value of the antenna is the maximum SAR value.
Optionally, the determining module 202 is specifically configured to: determining SAR influence values of each frequency band on the antenna according to the frequency of the frequency band; wherein, the SAR influence value of the frequency band with high frequency is larger than the SAR influence value of the frequency band with low frequency.
