In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
Referring to fig. 1, fig. 1 is a flowchart of an antenna operating method according to an embodiment of the present invention, where the method is applied to a mobile terminal, where the mobile terminal at least includes a first antenna and a second antenna, and as shown in fig. 1, the method includes the following steps:
The first antenna and the second antenna may be antennas applied to different networks, for example: the first antenna is a mobile communication network antenna (such as an LTE antenna or a 5G antenna), and the second antenna is a positioning system antenna (such as a GPS antenna).
The simultaneous operation of the first antenna and the second antenna may be that the operation time of the first antenna and the operation time of the second antenna overlap, for example: the mobile terminal uses the mobile communication network and carries out positioning, and at the moment, the mobile communication network antenna and the positioning system antenna of the mobile terminal work simultaneously.
It should be noted that, in the embodiment of the present invention, the operating frequency value of the antenna may be an operating frequency range (or an operating frequency band), for example: the GPS antenna works in an L1 frequency band, the working frequency value is 1575.42MHz +/-1.023 MHz, the LTE antenna works in a band39, the working frequency value is 1880 MHz-1920 MHz in a TDD working mode. Then, the frequency difference between the operating frequency value of the first antenna and the operating frequency value of the second antenna may be a minimum difference between the operating frequency value of the first antenna and the operating frequency value of the second antenna, for example: the GPS antenna works in an L1 frequency band, the LTE antenna works in a band39 which is a TDD working mode, and the minimum difference is the difference between 1880MHz and 1575.42MHz plus 1.023 MHz. Of course, this is not limited, for example: the difference may be a difference between a center frequency point of the operating frequency value of the first antenna and a center frequency point of the operating frequency value of the second antenna.
The preset frequency threshold may be configured in advance by the mobile terminal, or defined in a protocol, for example: 350MHz or 400MHz, etc., without limitation.
If it is determined in step 101 that the frequency difference is smaller than or equal to the preset frequency threshold, step 102 is executed, and if the frequency difference is greater than the preset frequency threshold, the process may be ended, or step 101 may be continuously executed, which is not limited in the embodiment of the present invention.
And 102, if the frequency difference is smaller than or equal to the preset frequency threshold, increasing the isolation between the first antenna and the second antenna.
It should be noted that, in the embodiment of the present invention, increasing the isolation between the first antenna and the second antenna may include various embodiments, for example: and if the first antenna and the second antenna share the same middle frame radiator, the middle frame radiator is cut off, so that the isolation between the first antenna and the second antenna is increased. Since the radiator of the middle frame is blocked, the isolation between the first antenna and the second antenna is naturally increased. The isolation of the middle frame radiator may be achieved by grounding a ground point disposed in the first antenna or the second antenna, so that a return path of a signal of the first antenna or the second antenna is terminated at the ground point. Of course, the middle frame radiator may be isolated by disposing a physical switch on the middle frame radiator, and disconnecting the middle frame radiator by the physical switch so that a gap exists between the first antenna and the second antenna.
By separating the middle frame radiator and increasing the isolation between the first antenna and the second antenna, the isolation between the first antenna and the second antenna can be greatly increased, so that the interference between the first antenna and the second antenna can be reduced to a greater extent and even eliminated.
Of course, in the embodiment of the present invention, increasing the isolation between the first antenna and the second antenna may also include: adjusting the working length of the first antenna or the second antenna so that the isolation of the first antenna from the second antenna is increased.
The adjusting of the working length of the first antenna or the second antenna may be grounding a grounding point disposed in the first antenna or the second antenna, so that a return path of a signal of the first antenna or the second antenna is terminated at the grounding point, thereby achieving the purpose of adjusting the working length of the first antenna or the second antenna, and increasing the isolation between the first antenna and the second antenna. Of course, the adjusting of the working length of the first antenna or the second antenna may also be to configure a physical switch on the first antenna or the second antenna, so as to disconnect the first antenna or the second antenna through the physical switch, so that only part of the first antenna or the second antenna is used for working, and further, the purpose of adjusting the working length of the first antenna or the second antenna is achieved, so that the isolation between the first antenna and the second antenna is increased. The adjusting of the working length of the first antenna or the second antenna may be to shorten the working length of the first antenna or the second antenna, so as to achieve an effect of increasing the isolation between the first antenna and the second antenna.
The isolation between the first antenna and the second antenna is increased by adjusting the working length of the first antenna or the second antenna, so that the first antenna and the second antenna do not share the same middle frame radiator, and the effect of increasing the isolation between the first antenna and the second antenna is achieved.
In the embodiment of the present invention, whether interference may exist between two antennas that the mobile terminal simultaneously operates may be determined by whether the frequency difference is smaller than or equal to the preset frequency threshold, and if the frequency difference is smaller than or equal to the preset frequency threshold, interference may exist between the first antenna and the second antenna, so as to increase the isolation between the first antenna and the second antenna, so as to reduce or eliminate the interference between the first antenna and the second antenna, and achieve an effect of improving the communication performance of the mobile terminal.
For example: the first antenna is an LTE antenna, the second antenna is a GPS antenna and operates simultaneously, wherein the LTE antenna operates in band39 and in a TDD operating mode, an operating frequency value is 1880MHz to 1920MHz, the GPS antenna operates in an L1 frequency band, the operating frequency value is 1575.42MHz +1.023MHz, and the operating frequency values of the two antennas are very close to each other to satisfy the condition in step 202, thereby increasing the isolation between the LTE antenna and the GPS antenna, reducing or eliminating the interference between the LTE antenna and the GPS antenna, and improving the positioning performance of the mobile terminal.
In an embodiment of the present invention, the Mobile terminal may be a Mobile terminal including multiple antennas, such as a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device).
In this way, in the embodiment of the present invention, in a case where the first antenna and the second antenna operate simultaneously, it is determined whether a frequency difference value between an operating frequency value of the first antenna and an operating frequency value of the second antenna is less than or equal to a preset frequency threshold; and if the frequency difference is smaller than or equal to the preset frequency threshold, increasing the isolation between the first antenna and the second antenna. Thereby antenna interference of the mobile terminal can be reduced.
Referring to fig. 2, fig. 2 is a flowchart of another antenna operating method according to an embodiment of the present invention, where the method is applied to a mobile terminal, where the mobile terminal includes at least a first antenna and a second antenna, and the present embodiment is mainly different from the embodiment shown in fig. 1 in that the first antenna is a mobile communication network antenna, a ground point is disposed on the first antenna, and the mobile terminal is provided with a control switch for controlling whether the ground point is grounded. As shown in fig. 2, the method comprises the following steps:
In this embodiment, the position of the ground point in the first antenna is not limited, for example: as shown in fig. 3, the mobile terminal includes a first antenna 301, a control switch 302, and a second antenna 303, wherein a grounding point 3011 may be provided with a left position of the first antenna 301, and whether the grounding point is grounded is controlled by the control switch 302. Of course, fig. 3 is only a preferred example, and in this embodiment, the position of the docking point is not limited, and any position on the first antenna 301 may be used.
In addition, the grounding point may be a grounding point added to the first antenna in the process of developing and debugging the performance of the antenna, and in this example embodiment, the control switch is added to the grounding point, so that the effect of increasing the isolation between the first antenna and the second antenna can be achieved, the modification to the mobile terminal is reduced, and the effect of saving the cost is achieved. The position of the grounding point may thus depend on requirements such as the actual standing wave state at the time of antenna tuning. Of course, the grounding point may also be a grounding point added to the first antenna in this embodiment, so that the position of the grounding point can be flexibly designed, so as to make the communication performance of the terminal better.
The control of the grounding point to be grounded by the control switch may be performed by closing the control switch to control the grounding point to be grounded.
In step 202, when the grounding point is grounded, in this way, in the case that the first antenna and the second antenna share the same middle frame radiator, the middle frame radiator may be cut off, so that the isolation between the first antenna and the second antenna is increased. And under the condition that the first antenna and the second antenna do not share the same middle frame radiator, when the grounding point is grounded, the working length of the first antenna or the second antenna can be adjusted, so that the isolation between the first antenna and the second antenna is increased,
in this embodiment, in step 202, the grounding point is controlled to be grounded through the control switch, so that the complexity of the mobile terminal can be reduced while the antenna interference is reduced or eliminated, because the adjustment of the antenna structure of the mobile terminal is not increased.
As an alternative embodiment, the antenna tuner of the first antenna includes N states and a target state, where the N states are used for adjusting the radiation efficiency of the first antenna in a case where the ground point is not grounded, and N is an integer greater than 1;
after determining whether a frequency difference between the operating frequency value of the first antenna and the operating frequency value of the second antenna is less than a preset frequency threshold, the method further includes:
and when the frequency difference is smaller than or equal to the preset frequency threshold, adjusting the antenna tuner of the first antenna to the target state, wherein when the grounding point is grounded and the antenna tuner is in the target state, the radiation efficiency of the first antenna is greater than other radiation efficiencies, the other radiation efficiencies are that the grounding point is grounded and the antenna tuner is in any one of the N states, and the radiation efficiency of the first antenna is greater than the other radiation efficiencies.
In this embodiment, the antenna tuner can change the antenna matching of the first antenna in different states, so as to achieve the purpose of adjusting the radiation efficiency of the first antenna. Wherein, the above-mentioned changing the antenna matching of the first antenna may also be referred to as changing the standing wave of the first antenna, thereby having the best effect of radiation for different frequencies.
The N states and the target state may be as shown in fig. 3, and the mobile terminal includes an antenna tuner (tuner) 304, which includes N states and an N +1 state, where the N +1 state is the target state added in this embodiment.
The N states are used for adjusting the radiation efficiency of the first antenna when the ground point is not grounded, where the N states are used for adjusting the radiation efficiency of the first antenna when the ground point is not grounded, and the N states are used for changing the state of a switch according to the working frequency value of the first antenna to change the antenna matching and achieve the optimal radiation efficiency of the first antenna. In addition, the antenna tuner may be switched between the states through a switch, which may be specifically referred to as a switch in the antenna tuner shown in fig. 3.
The target state is a state configured for the case where the grounding point is grounded in the present embodiment, for example: and under the condition that the grounding point is grounded, debugging the first antenna to enable the first antenna to achieve the maximum radiation efficiency under the condition, and taking the state of the antenna tuner as the target state when the maximum radiation effect is achieved. In the embodiment of the present invention, it is not limited to debugging each mobile terminal, and the target state obtained by debugging may be configured in each mobile terminal of the same model by debugging one or more mobile terminals of the model.
In this embodiment, since the target state is configured, the performance of the operating frequency value of the first antenna in step 201 can be improved in this state, and it can be ensured that the performance of the first antenna is not reduced when the grounding point is grounded. For example: the first antenna is an LET antenna and operates at the band39, so that when the grounding point is grounded and the state of the antenna tuner (tuner) is in the target state, the performance of the LTE antenna at the band39 is not reduced compared with the performance of the LTE antenna without the grounding point.
Optionally, after the increasing the isolation between the first antenna and the second antenna, the method further includes:
under the condition that the first antenna and the second antenna work simultaneously, if the frequency difference value between the working frequency value of the first antenna and the working frequency value of the second antenna is larger than the preset frequency threshold value, the grounding point is controlled to be disconnected with the ground through the control switch, and the radiation efficiency of the first antenna is adjusted through the N states of the antenna tuner; or
Under the condition that the first antenna works and the second antenna does not work, the grounding point is controlled to be disconnected from the ground through the control switch, and the radiation efficiency of the first antenna is adjusted through the N states of the antenna tuner.
Under the condition that the first antenna and the second antenna work simultaneously, but the frequency difference value of the working frequency value of the first antenna and the working frequency value of the second antenna is larger than the preset frequency threshold value, the fact that no interference exists between the first antenna and the second antenna or the interference is negligible can be confirmed, and therefore under the condition, the grounding point is controlled to be disconnected from the ground, the radiation efficiency of the first antenna is adjusted through N states of the antenna tuner, and the working performance of the first antenna is guaranteed. For example: the LTE antenna does not work in band39, and the GPS antenna works simultaneously, can regard GPS performance not to be influenced this moment, can not have the location failure problem to the antenna tuner can switch between state 1 to state N according to the requirement of actual annotating the net, with the working property of guaranteeing first antenna.
When the first antenna works and the second antenna does not work, it is determined that there is no antenna interference, and the grounding point can be controlled to be disconnected from the ground through the control switch, and the radiation efficiency of the first antenna is adjusted through the N states of the antenna tuner, so as to improve the working performance of the first antenna.
Of course, when it is determined next time that the execution condition of step 202 is satisfied, step 202 may be re-executed, for example: when the LTE antenna operating band39 and the GPS antenna coexist, step 202 reduces the interference of the LTE antenna to the GPS antenna, and improves the positioning performance of the mobile terminal.
In addition, in this embodiment, the control switch and the antenna tuner may be controlled by a processor of the mobile terminal, but this is not limited, for example: the control of the control switch and the antenna tuner may also be performed by other chips than the processor.
In this embodiment, various optional implementation manners are added on the basis of the embodiment shown in fig. 1, and all the implementation manners can reduce the antenna interference of the mobile terminal, and can also achieve the beneficial effects of improving the working performance of the mobile communication network antenna, and the like.
