Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
The scheme of the application is suitable for the mobile terminal, and the mobile terminal can be a mobile phone, a tablet computer, a notebook computer and the like.
In the embodiment of the application, the mobile terminal is provided with an antenna and an antenna auxiliary unit, the antenna auxiliary unit at least comprises another antenna which is connected with the antenna of the mobile terminal in parallel, the overall signal radiation performance of the mobile terminal can be improved through the antenna auxiliary unit, and the situations that the mobile terminal is in a signal blind area and communication abnormity occurs are reduced.
For ease of understanding, the mobile terminal of the present application will be described first.
For example, referring to fig. 1, a schematic diagram of a component structure of the mobile terminal of the present application is shown.
As can be seen from fig. 1: the mobile terminal comprises at least a processor 101, a first antenna 102 and an auxiliary antenna unit 103. The processor is coupled to the first antenna and the auxiliary antenna element.
The auxiliary antenna unit 103 at least includes a second antenna 104 connected in parallel with the first antenna 102. For example, the first antenna and the second antenna may be connected to the same feed point. Wherein the operating frequency band of the first antenna and the operating frequency band of the second antenna at least partially overlap.
It can be understood that, because the operating frequency bands of the first antenna and the second antenna overlap, in a case where the radiation performance of the first antenna is weak, by enhancing the radiation intensity of the second antenna, it is beneficial to enhance the signal reception performance of the mobile terminal in at least a part of the operating frequency bands supported by the first antenna.
The processor 101 is configured to obtain a current radiation performance parameter of a first antenna in the mobile terminal; acquiring whether the radiation performance of the first antenna meets a first condition or not based on the radiation performance parameter; and controlling to enhance the radiation intensity of an auxiliary antenna unit in the mobile terminal under the condition that the radiation performance of the first antenna does not meet the first condition.
In particular, the specific operations performed by the processor may be referred to as the operations at the mobile terminal side in fig. 2-6 as follows.
It is to be understood that fig. 1 is merely a schematic diagram of a mobile terminal. In practical applications, the connection between the processor of the mobile terminal and the first antenna and the second antenna of the auxiliary antenna unit is specifically realized by a signal processing module, for example, the signal processing module may be a radio frequency module, a baseband module, or the like.
As shown in fig. 1, a radio frequency module 105 may be connected between the processor 101 and the first antenna and the second antenna of the auxiliary antenna unit.
Of course, the mobile terminal may further include a memory 106 for storing program data required for the mobile terminal to perform operations.
In addition, the mobile terminal may further include a display screen, an input unit, and the like, which are not listed herein.
With reference to the above, referring to fig. 2, which shows a flowchart of an antenna control method according to the present application, the method of the present embodiment may be applied to, for example, an upper mobile terminal, and the method of the present embodiment includes the following steps:
s201, obtaining the current radiation performance parameter of a first antenna in the mobile terminal.
The radiation performance parameter of the first antenna can be a parameter which characterizes the radiation performance of the first antenna, and the radiation performance is a relevant parameter which influences the transmission and the reception of signals by the first antenna.
For example, the radiation performance parameter may include the radiation intensity of the first antenna, and the like.
The radiation performance parameter may be an overall average radiation performance of the first antenna in different directional regions. For example, in the case where the radiation performance parameter is the radiation intensity, the radiation intensity may be an average radiation intensity of the first antenna in each directional area.
Optionally, in order to obtain more comprehensive understanding of the radiation performance of the first antenna in each directional area, radiation performance parameters of the first antenna in each directional area may be obtained. For example, the radiation intensity of the first antenna in each directional area is acquired. The direction area is a direction range area in the omnidirectional radiation of the first antenna, and the radiation intensity of the first antenna in each direction area can reflect the radiation pattern of the first antenna.
S202, based on the radiation performance parameters, whether the radiation performance of the first antenna meets a first condition is obtained.
It can be understood that the radiation performance of the first antenna can be determined by the radiation performance parameter, and the situation of the mobile terminal for signal receiving and transmitting based on the first antenna can be determined by the radiation performance of the first antenna, so as to determine whether the mobile terminal is abnormal in signal receiving and transmitting or in a signal blind area.
The first condition can represent that the radiation performance of the first antenna can meet the requirements of receiving and sending signals of the mobile terminal.
The first condition can be set according to the specific content contained in the radiation performance parameter and the actual requirement.
For example, in one possible case, the radiation intensity of the first antenna may be determined based on the radiation performance parameter, e.g., the radiation performance parameter comprises the radiation intensity of the first antenna; or the radiation intensity of the first antenna is estimated based on the radiation performance parameters. Accordingly, it can be detected whether the radiation intensity of the first antenna exceeds a radiation threshold. And if the radiation intensity of the first antenna exceeds the radiation intensity, confirming that the radiation performance of the first antenna is consistent with that of the first antenna.
It can be understood that, in the case of the first antenna having a current zero point, that is, the first antenna having a signal blind area, the first antenna having a current zero point or a signal blind area can be found in time by detecting the radiation intensity of the first antenna. For example, in the case that the radiation intensity of the first antenna is too low, the first antenna may have a current zero point, so that the first antenna has a signal blind zone.
Optionally, in the case of obtaining the radiation performance parameters of the first antenna in the different direction areas, in step S202, it may also be obtained whether the radiation performance parameters of the first antenna in each direction area satisfy the first condition, and if the radiation performance parameters of the first antenna in at least one direction area do not satisfy the first condition, the radiation performance of the first antenna is considered to be not satisfied with the first condition.
For example, taking the radiation performance parameter as the radiation intensity, it may be detected whether the radiation intensity of the first antenna in each directional area exceeds a radiation threshold, and if so, the first condition is considered to be met.
S203, under the condition that the radiation performance of the first antenna does not meet the first condition, controlling and enhancing the radiation intensity of an auxiliary antenna unit in the mobile terminal.
The auxiliary antenna unit at least comprises a second antenna connected with the first antenna in parallel, and the working frequency bands of the first antenna and the second antenna are at least partially overlapped.
The radiation performance of the first antenna does not meet the requirement that the first antenna possibly cannot guarantee signal receiving and sending of the mobile terminal, and the mobile terminal has the risk of communication abnormity or being in a signal blind area. In this case, in order to reduce or even avoid signal reception and transmission abnormality of the mobile terminal, the radiation intensity of the auxiliary antenna unit in the mobile terminal can be enhanced.
Because the auxiliary antenna unit at least comprises the second antenna connected with the first antenna in parallel, the radiation intensity of the second antenna is actually enhanced by enhancing the radiation intensity of the auxiliary antenna unit, thereby being beneficial to enhancing the integral signal radiation performance of the mobile terminal; and because the working frequency bands of the second antenna and the first antenna are overlapped, the signal radiation of the second antenna can make up the defect that the signal radiation performance of the first antenna in the corresponding frequency band is insufficient.
For example, assuming that the frequency band supported by the first antenna is frequency band 1, the frequency band supported by the second antenna may also be frequency band 1, or support multiple frequency bands including frequency band 1. On this basis, once the radiation performance of the first antenna is low, the receiving and sending of the mobile terminal to the relevant signals in the frequency band 1 cannot be met, then the radiation intensity of the second antenna is enhanced, so that the second antenna can also support the sending and receiving of the signals in the frequency band 1, thereby being beneficial to ensuring the receiving and sending of the whole mobile terminal to the signals in the frequency band 1, and further reducing the occurrence of signal blind areas or abnormal communication conditions of the mobile terminal in the frequency band 1.
Alternatively, considering that the second antenna of the auxiliary antenna unit can radiate in a plurality of different directional regions, the radiation intensity of the auxiliary antenna unit in different directional regions can be controlled to be enhanced, so as to control the radiation intensity of the second antenna in different directional regions to be enhanced. Wherein the radiation intensity of the second antenna in different directional areas can be different.
For example, the radiation performance parameters of the first antenna in the different direction areas may be combined to determine the radiation intensities of the auxiliary antenna element in the different directions, and the radiation intensity of the second antenna in the different directions is controlled according to the determined radiation intensities of the radiation antenna element in the different directions, so as to enhance the radiation intensity of the second antenna as a whole. As can be seen from the above, in addition to the first antenna, the mobile terminal in the present application may further include an auxiliary antenna unit, where the auxiliary antenna unit at least includes a second antenna connected in parallel with the first antenna, and an operating frequency band of the second antenna at least partially overlaps an operating frequency band of the first antenna. Based on this, under the condition that the radiation performance of the first antenna in the mobile terminal is determined to be not in accordance with the radiation performance parameter of the first antenna, the radiation intensity of the second antenna can be enhanced by enhancing the radiation intensity of the auxiliary antenna unit in the mobile terminal, so as to make up for the defect that the radiation performance of the first antenna is not in accordance with the condition, and enhance the signal receiving performance of the mobile terminal, thereby being beneficial to reducing the conditions that the mobile terminal is in a signal blind area and has communication abnormity due to the fact that the radiation performance of the first antenna is not in accordance with the condition.
It is understood that, in the embodiments of the present application, there may be various ways to control the radiation intensity of the auxiliary antenna element in the enhanced mobile terminal.
In one possible implementation, the second antenna in the auxiliary antenna unit may be in a non-operating state before the radiation performance of the first antenna does not satisfy the first condition. In this case, the second antenna of the auxiliary antenna unit in the mobile terminal may be controlled to be switched from the non-operating state to the operating state, so as to achieve the purpose of enhancing the radiation intensity of the second antenna.
It can be understood that, in the case where the radiation performance of the first antenna satisfies the first condition, setting the second antenna in the non-operating state is beneficial to reducing power consumption; and under the condition that the radiation performance of the first antenna does not meet the first condition, the second antenna is switched to the working state, so that the defect of poor radiation performance of the first antenna can be effectively overcome, the directional area with poor radiation performance in the directional diagram of the first antenna is received in an auxiliary mode through the second antenna, and the risk that the mobile terminal is located in a signal blind area is reduced.
In yet another possible implementation manner, the radiation intensity of the auxiliary antenna unit is increased, so that the radiation intensity level of the radiation emitted by the second antenna in the auxiliary antenna unit is adjusted to increase the radiation intensity of the second antenna. The adjusting of the radiation intensity of the second antenna may be adjusting the radiation intensity of the second antenna according to the radiation performance of the first antenna.
It will be appreciated that in order to be able to vary the radiation intensity of the second antenna, the second antenna may also be connected to an antenna adjustment circuit, the antenna parameters of which are adjusted to control the second antenna to be at different radiation intensities. Accordingly, the auxiliary antenna circuit may further include: an antenna adjustment circuit coupled to the second antenna.
Fig. 3 is a schematic diagram illustrating another structure of an antenna auxiliary unit in the mobile terminal of the present application.
As can be seen from comparing fig. 1 and 3, in fig. 3, the antenna auxiliary unit 103 includes, in addition to the second antenna 104 connected in parallel with the first antenna: and an antenna adjusting circuit 107 connected to the second antenna 104.
The antenna adjusting circuit 107 is used to adjust the antenna parameters required by the second antenna.
In practical application, components such as an adjusting switch, an adjustable capacitor, an adjustable resistor and the like can be arranged in the antenna adjusting circuit according to requirements. By controlling the working parameters of each component in the antenna adjusting circuit, the antenna parameters corresponding to the second antenna can be adjusted, and then the radiation intensity of the second antenna is adjusted.
Optionally, in order to enable the antenna adjusting circuit to respond to the control of the processor and complete the adjustment of the operating parameter, a control circuit (not shown in fig. 3) may be further included between the antenna adjusting circuit and the processor.
As described in detail below in conjunction with fig. 4. Fig. 4 is a schematic flowchart of another antenna control method according to the present application, where the method of this embodiment may include:
s401, obtaining the current radiation performance parameter of the first antenna in the mobile terminal.
S402, based on the radiation performance parameters, whether the radiation performance of the first antenna meets a first condition is obtained.
The above steps S401 and S402 can participate in the related description of the previous embodiments, and are not described herein.
S403, when the radiation performance of the first antenna does not meet the first condition, the radiation intensity of the second antenna is enhanced by adjusting the antenna parameters of the antenna adjusting circuit in the auxiliary antenna unit.
Wherein the antenna adjusting circuit is connected with the second antenna. The antenna parameter of the antenna adjusting circuit is a working parameter which is set in the antenna adjusting circuit and is used for controlling the radiation intensity of the second antenna.
It will be appreciated that in practice, when the second antenna is switched from the non-operating state to the operating state, the radiation intensity of the second antenna will increase from no radiation intensity to a certain radiation intensity. However, in case of different radiation performance of the first antenna, the requirements for the radiation intensity of the second antenna may also differ. Therefore, the antenna parameters required by the antenna adjusting circuit can be determined according to the current radiation performance of the first antenna, so as to reasonably control the radiation intensity of the second antenna.
As an optional manner, in order to control the radiation intensity of the second antenna more reasonably under the condition that the radiation performance of the first antenna does not satisfy the first condition, so as to achieve effective reduction of radiation performance degradation in the working frequency band corresponding to the first antenna, even occurrence of signal blind areas, by enhancing the radiation intensity of the second antenna, in this application, a target antenna parameter corresponding to the radiation performance of the first antenna may also be determined according to a corresponding relationship between different radiation performance and the antenna parameter, and then, the antenna parameter adopted by the antenna adjusting circuit is adjusted according to the target antenna parameter, so as to enhance the radiation intensity of the second antenna.
The corresponding relation between different radiation performances and antenna parameters can be set according to actual needs; or the antenna parameters suitable for different radiation performances of the first antenna can be determined in advance by testing the first antenna and the second antenna.
The antenna parameter used for adjusting the antenna adjusting circuit according to the target antenna parameter can be used for controlling the antenna adjusting circuit to work in the target antenna parameter, so that the second antenna is finally enabled to be in the radiation intensity, and the purpose of enhancing the radiation intensity of the second antenna is achieved.
It is to be understood that, considering that the radiation intensity of the second antenna may be different in multiple directional regions, in the embodiment of the present application, the radiation intensity of the second antenna in each of the different directional regions may also be controlled and enhanced by adjusting the antenna parameter of the antenna adjusting circuit in the auxiliary antenna unit, where the radiation intensity of the second antenna in different directions may be different.
Optionally, in order to more reasonably control and enhance the radiation intensity of the second antenna, the radiation performance parameters of the first antenna in the mobile terminal in the different direction areas may be obtained, and then, the target antenna parameters corresponding to the radiation performance parameters of the first antenna in the different direction areas are determined according to the corresponding relationship between the different radiation performance parameters and the antenna parameters, so as to control the antenna parameters adopted by the antenna adjusting circuit according to the target antenna parameters, so as to control the radiation intensity of the second antenna in the different direction areas, and enhance the overall radiation intensity of the second antenna.
It can be understood that, considering that the antenna adjusting circuit is composed of different circuit components, according to the target antenna parameter, the operating parameters of each component in the antenna adjusting circuit can be adjusted to enhance the radiation intensity of the second antenna or control the radiation intensity of the second antenna in different direction areas.
To facilitate understanding of the solution of the present application, a case is described as an example below, for example, referring to fig. 5, which shows another schematic flow chart of an antenna control method of the present application, where the method of the present embodiment may include:
s501, obtaining the radiation intensity of a first antenna in the mobile terminal in each direction area.
S502, detecting whether the radiation intensity of the first antenna in each direction area reaches an intensity threshold value.
S503, if the first antenna has a radiation intensity in at least one direction area lower than the intensity threshold, determining a target antenna parameter corresponding to the radiation intensity of the first antenna in each direction area according to the correspondence between different radiation performances and antenna parameters.
The target antenna parameter may include an operating parameter required by each component in the antenna adjusting circuit, such as an operating state of each component, a required operating parameter value, and the like.
For example, the target antenna parameters may include the switch states of different adjustable switches in the antenna adjustment circuit, target capacitance values corresponding to the adjustable capacitors, target resistance values of the adjustable resistors, and so on.
Optionally, the target antenna parameter is determined based on the radiation intensity in at least one directional region of the first antenna where the radiation intensity is below the intensity threshold. For example, different antenna parameters suitable for the antenna adjusting circuit are tested in advance under the condition that the radiation intensity of the first antenna in different directions is lower than the intensity threshold value, so that the antenna parameters required to be set under the different conditions of the radiation intensity of the first antenna in different direction areas are determined.
S504, according to the target antenna parameter, the operating parameters of each device in the antenna adjusting circuit can be controlled to control the radiation intensity of the second antenna in different directional regions, and enhance the radiation intensity of the second antenna in each directional region.
It can be understood that, according to the target antenna parameter, the processor may control and adjust the operating state and the operating parameter of each component in the antenna adjusting circuit, so as to adjust the radiation intensity of the second antenna.
