Thus, a feature defining "a first", "a second", or a third "may explicitly or implicitly include one or more such feature.
For ease of understanding, the description of the concepts related to the embodiments of the application is given in part by way of example for reference.
1. Aperture tuning
For example, the aperture tuning may be applied to the application environment shown in fig. 1, where a set of switches for aperture tuning is added between the antenna and the ground, and the electronic components connected to the antenna are changed by conducting different switches in the aperture tuning switch, which is equivalent to changing the matching circuit of the antenna, and further changing the effective electrical length of the antenna, so as to adjust the resonant frequency of the antenna and match the current operating frequency of the electronic device.
It should be understood that the aperture tuning switch shown in fig. 1 is only an example and that in other embodiments of the application the aperture tuning switch may comprise more or fewer switches than shown in fig. 1.
2. Antenna logic look-up table
When the electronic equipment works in different frequency bands, the corresponding antenna can be called to work, wherein each antenna is connected with an aperture tuning switch. Because the states of the aperture tuning switches are different, the matching states of the corresponding antennas are different, so that in order to enable the antennas to keep good matching states in all frequency bands, the states of the aperture tuning switches corresponding to the antennas in different frequency bands are usually determined in a laboratory through a large number of experiments. As the number of antennas on the electronic device is increasing, in order to improve the performance of the electronic device, the states of the aperture tuning switches corresponding to the antennas used in different frequency bands are generally stored in an antenna logic lookup table, so as to facilitate the call of the electronic device.
There are typically a plurality of switches on one aperture tuning switch, and illustratively, as shown in fig. 2, the aperture tuning switch S0 includes 4 switches, namely, a switch K0, a switch K1, a switch K2, and a switch K3. Each switch is connected with an electronic element, and the matching circuit of the antenna can be changed by changing the conducting state of each switch, so that the resonant frequency of the antenna can be changed. The states of the aperture tuning switches are used to indicate the on-state of the respective switches. Wherein the state of the aperture tuning switch may be represented by a numerical value, and exemplary, the switch K0, the switch K1, the switch K2, and the switch K3 may be indicated by a numerical value of "0" as being in an on state; a value of "1" indicates that switch K0 is off, and switches K1, K2, and K3 are on; the value of "2" indicates that the switch K0 and the switch K1 are in an off state, and the switch K2 and the switch K3 are in an on state; the value of "3" indicates that the switch K0, the switch K1 and the switch K2 are in an off state, and the switch K3 is in an on state; … …; the value "14" indicates that the switch K0, the switch K1 and the switch K2 are in an on state, and the switch K3 is in an off state; the value "15" indicates that the switches K0, K1, K2 and K3 are all in the off state.
For example, an electronic device having 11 antennas, each corresponding to one or more aperture tuning switches, is illustrated, and the antenna logic look-up table may be shown in table 1.
TABLE 1
It should be understood that when the electronic device operates in different operating frequency bands, the matching states of the corresponding antennas are different. The matching state corresponding to the current operating frequency band can be found by looking up an antenna logic look-up table. The antenna logic look-up table is generally classified into an antenna logic index table when the antenna is in a transmitting state and an antenna logic index table when the antenna is in a receiving state. In one possible case, the antenna may also receive a signal when the antenna is in a state of transmitting the signal, and therefore, when setting the state of the aperture tuning switch of the transmitting state of the antenna, the matching state of the antenna when receiving the signal needs to be considered, and therefore, the state of the aperture tuning switch when the antenna is in the state of transmitting the signal is a state in which the transmitting signal and the receiving signal are combined. When the antenna is in a state of receiving a signal, the antenna will not normally transmit a signal, and therefore, when the antenna is in a state of receiving a signal, the state of the aperture tuning switch is usually only considered that the antenna is in a state of receiving a signal. In one possible case, the antenna cannot receive a signal when in a state of transmitting the signal, and therefore, when setting the state of the aperture tuning switch of the transmitting state of the antenna, it is unnecessary to consider the matching state of the antenna when in a state of receiving the signal.
At present, as functions integrated on electronic devices are more and more increased, the number of electronic devices arranged on the electronic devices is more and more increased. For example, the mobile phone can realize the function of a full screen, or the mobile phone adopts a multi-camera module, or the tablet personal computer uses a large battery, or the mobile phone adopts a large-area fingerprint identification function. These functions will result in higher and higher screen ratios and narrower borders for the electronic device. On the one hand, the increasingly larger battery, camera module and fingerprint identification module squeeze up the available space inside the electronic equipment, so that the antenna headroom in the electronic equipment is increasingly smaller, and simultaneously, the antenna size is continuously reduced, thereby leading to the reduction of the antenna efficiency. On the other hand, the narrower and narrower bezel results in a smaller and smaller distance between the antenna and the screen edge, resulting in further reduced antenna efficiency.
In addition, with the development of long term evolution (Long Term Evolution, LTE) and new wireless (5th Generation Mobile Communication Technology New Radio,5GNR) technologies, where LTE employs carrier aggregation (Carrier Aggregation, CA), 5GNR employs Multiple-Input Multiple-Output (MIMO) technology to achieve higher data rates. Both techniques require the simultaneous use of multiple antennas for signal transceiving. Meanwhile, non-cellular communication modules, such as wireless fidelity (Wireless Fidelity, wi-Fi), bluetooth, global positioning system (Global Position System, GPS), ultra Wideband (UWB), etc., also require additional antennas to be deployed on the electronic device. In summary, the number of antennas on electronic devices is increasing, and more antennas are required to be designed in smaller and smaller spaces, which means further downsizing of the antennas and further reduction of antenna efficiency.
In order to combat the reduced antenna efficiency due to the reduced antenna size and environmental changes, the electronic device may change the matching state of the antenna through the aperture tuning switch to perform antenna tuning. The electronic equipment can determine the state of each aperture tuning switch under the current working frequency band by searching an antenna logic lookup table, and set the conduction state of each switch in the aperture tuning switch according to the result obtained by searching so as to adjust the matching circuit of the antenna and change the resonant frequency of the antenna. However, as the number of antennas on the electronic device increases, there is mutual coupling between antennas with a relatively short distance, which results in that the matching state of the antennas cannot be adjusted to a better state according to the state of each aperture tuning switch found in the antenna logic lookup table, thereby resulting in poor performance of the antennas.
The antenna tuning method provided by the embodiment of the application aims to solve the problem of poor antenna performance in the traditional technology.

In general, as shown in fig. 6, an electronic device may include a modem, a radio frequency chip, a radio frequency front end circuit, an antenna tuning module, a plurality of antennas, and aperture tuning switches corresponding to the respective antennas. The antenna tuning module obtains the working frequency band or frequency band combination of the antenna at the current moment from the modem and/or the radio frequency chip, searches for the state information of each aperture tuning switch from the antenna logic index table according to the working frequency band at the current moment, and then obtains the state of the final aperture tuning switch according to the state information of each aperture tuning switch obtained by coupling the antenna with the antenna at the current moment and searching. After the final aperture tuning switch state is obtained, the antenna tuning module adjusts each aperture tuning switch according to the final aperture tuning switch state. Wherein the antenna logic index table is typically stored in the antenna tuning module.
It should be understood that the foregoing is illustrative of an application scenario, and is not intended to limit the application scenario of the present application in any way.
The antenna tuning method provided by the embodiment of the present application is described in detail below with reference to fig. 7 to 12.
Fig. 7 is a flow chart of an antenna tuning method according to an embodiment of the present application, as shown in fig. 7, where the method includes:
S101, determining an index value according to the current working frequency band of the electronic equipment.
As shown in fig. 6, the antenna tuning module in the electronic device may determine the index value according to the current operating frequency band of the electronic device. The antenna tuning module may obtain the current operating frequency band of the electronic device from the modem and/or the radio frequency chip. For example, the antenna tuning module may obtain first information from the modem, where the first information includes a current operating frequency band of the electronic device. Or the antenna tuning module may receive second information sent by the radio frequency chip, where the second information may be used to indicate a current operating frequency band of the electronic device.
The antenna logic index table (i.e., a preset tuning parameter table) is a state (may be called a tuning parameter) of an aperture tuning switch corresponding to different working frequency bands, which is determined according to multiple tests in a laboratory, and after the tuning parameters corresponding to the different working frequency bands are determined, the tuning parameters are stored in the antenna logic index table, and an index value is set for each tuning parameter. Since the tuning parameters correspond to the operating frequency bands, the operating frequency bands correspond to the index values. After the current working frequency band of the electronic equipment is obtained, an index value for searching tuning parameters corresponding to the current working frequency band in an antenna logic index table can be obtained according to the corresponding relation between the working frequency band and the index value.
It should be appreciated that the electronic device may correspond to the same tuning parameters over different operating frequency bands, which may result in the number of tuning parameters in the antenna logic index table being less than the number of operating frequency bands of the electronic device.
For example, as shown in fig. 8, the index values corresponding to the operating frequency band 0 and the operating frequency band 2 are both index value 0, and the index value 0 corresponds to the tuning parameter 0, that is, when the electronic device operates in the operating frequency band 0 and the operating frequency band 2, the states of the corresponding aperture tuning switches are the same, and are the states of the aperture tuning switches indicated by the tuning parameter 0. Similarly, the index values corresponding to the working frequency band 1 and the working frequency band 3 are both index value 1, and the index value 1 corresponds to the tuning parameter 1, that is, when the electronic device works in the working frequency band 1 and the working frequency band 3, the states of the corresponding aperture tuning switches are the same, and are the states of the aperture tuning switches indicated by the tuning parameter 1. The index value corresponding to the working frequency band N is an index value K, and the index value K corresponds to the tuning parameter K, namely, when the electronic equipment works on the working frequency band K, the state of the aperture tuning switch is the state of the aperture tuning switch indicated by the tuning parameter K.
S102, obtaining a first parameter set and a second parameter set according to the index value and a preset tuning parameter table.
The preset tuning parameter table may refer to an antenna logic index table, and the first parameter set refers to a set of tuning parameters of all aperture tuning switches on the electronic device when each antenna in the plurality of antennas transmits signals (corresponding to a first working state) in a current working frequency band, where the tuning parameters are used to indicate a conducting state of each switch in the aperture tuning switches. It should be understood that when an antenna transmits a signal, there is often a possibility of receiving the signal, so the antenna transmits the tuning parameter of the aperture tuning switch corresponding to the signal, and the situation that the antenna is in the receiving state needs to be considered. That is, the first parameter set is the on state of the aperture tuning switch in a state where the antenna transmits and receives signals simultaneously. The second parameter set refers to a set of tuning parameters of all aperture tuning switches on the electronic device when each antenna of the plurality of antennas receives only signals (corresponding to the second operating state) in the current operating frequency band.
It should be understood that the antenna logic look-up table (i.e., the preset tuning parameter table) is generally divided into an antenna logic index table when the antenna is in a transmitting state and an antenna logic index table when the antenna is in a receiving state. When the antenna is in a state of transmitting a signal, the antenna is also likely to receive a signal, and therefore, when tuning parameters of the transmitting state of the antenna are set, it is also necessary to consider the matching state of the antenna in a state of receiving a signal, that is, the tuning parameters when the antenna is in a state of transmitting a signal are tuning parameters that integrate the state of transmitting a signal and the state of receiving a signal. Since the antenna does not normally transmit a signal when the antenna is in a state of receiving a signal, the tuning parameter when the antenna is in a state of receiving a signal is generally considered only for the tuning parameter when the antenna is in a state of receiving a signal.
The antenna tuning module marks tunerdidx according to the index value obtained in S101. A first set of parameters is found from an antenna logic index table when the antenna is in a transmitting state, which may be denoted T tunerdidx. And according to the same index value, searching from an antenna logic index table when the antenna is in a receiving state to obtain a second parameter set, wherein the second parameter set can be marked as R [ tunerIdx ].
By way of example, table 1 is illustrated as a logical index table when the antenna is in a transmitting state. The index value obtained according to the current working frequency band is 0, and the first parameter set obtained according to the index value 0 and the antenna logic index table is:
| S0 | S1 | S2 | S3 | S4 | S5 | S6 | S7 | S8 | S9 | S10 |
| 9 | 1 | 3 | 6 | 4 | 7 | 5 | 6 | 4 | 3 | 2 |
s103, determining a first switch set.
The first switch set comprises a first switch, the first switch comprises a switch connected with a first antenna and a switch connected with a second antenna, the first antenna is an antenna used for transmitting signals at the current moment, and the second antenna comprises an antenna mutually coupled with the first antenna.
As the number of antennas arranged on the electronic device is increasing, each antenna can change the electrical length of the antenna through aperture tuning, and adjust the resonant frequency, the number of aperture tuning switches in the electronic device is also increasing. Thus, the electronic device may label each aperture tuning switch, assign a value to a different labeled aperture tuning switch, "0" indicating that the aperture tuning switch is not in use, and "1" indicating that the aperture tuning switch is on. And assigning values to the aperture tuning switches with different labels to form a group of vectors, namely switch vectors. The electronic device can adjust the resonant frequency of the antenna by changing the values in the switch vector and controlling the on state of the aperture tuning switch.
As shown in fig. 5 (a), the electronic device includes 12 antennas, namely, antenna 0, antenna 1, antenna 2, and antenna 3, … …, 11. Wherein, antenna 0 is connected with aperture tuning switch S0, antenna 1 is connected with aperture tuning switch S1, antenna 2 is connected with aperture tuning switch S2, antenna 3 is connected with aperture tuning switch S3, … … antenna 11 is connected with aperture tuning switch S11.
The switch vector may be as shown in table 2 and may be used to indicate whether the aperture tuning switch is enabled. Where "0" indicates that the aperture tuning switch is not enabled and "1" indicates that the aperture tuning switch is enabled.
TABLE 2
| S0 | S1 | S2 | S3 | S4 | S5 | S6 | S7 | S8 | S9 | S10 | S11 |
| 1 | 0 | 0 | 1 | 0 | 0 | 0 | 0 | 0 | 0 | 1 | 0 |
The switch vectors shown in table 2 indicate that the aperture tuning switch S0, the aperture tuning switch S3, and the aperture tuning switch S10 are in the activated state, and the other switches are in the deactivated state.
The first set of switches may refer to a set of first switches indicated in a first switching vector, the first switches may refer to an aperture tuning switch connected to a first antenna and an aperture tuning switch connected to a second switch, wherein the second antenna refers to an antenna that is mutually coupled with the first antenna in a current operating frequency band.
For example, continuing to take (a) in fig. 5 as an example, when the antenna in the electronic device in the state of transmitting a signal at the present moment is antenna 0, the first antenna refers to antenna 0. The working frequency band of the antenna 11 is the same as that of the antenna 0, and the distance between the antenna 11 and the antenna 0 is smaller than a preset threshold value, and the antenna 11 and the antenna 0 are mutually coupled. The distance between the antenna 1 and the antenna 0 is smaller than the preset threshold, but the operating frequency band of the antenna 1 is different from that of the antenna 0 and has a larger difference, so that the antenna 1 and the antenna 0 are not coupled. The operating frequency band of the antenna 6 is the same as that of the antenna 0, but the distance between the antenna 6 and the antenna 0 is far and is larger than the preset threshold, so that the antenna 6 and the antenna 0 are not coupled. That is, the first antenna is antenna 0, and the second antenna is antenna 11.
It should be appreciated that when an electronic device is operating in different operating frequency bands, the corresponding switching vectors are typically different. When the electronic equipment works in the same frequency band, the switching vector also changes when the antenna which is currently used is switched.
S104, determining target tuning parameters of the first antenna according to the first parameter set, the second parameter set and the first switch set.
The target tuning parameter of the first antenna may refer to an on state of an aperture tuning switch corresponding to the first antenna, and when the on state of the aperture tuning switch corresponding to the first antenna is set as the target tuning parameter, the performance of the first antenna is optimal.
It should be appreciated that, due to interactions between antennas in an electronic device, the target tuning parameter of the first antenna may include the on state of the aperture tuning switch corresponding to the first antenna. Alternatively, the target tuning parameter of the first antenna may include a conductive state of an aperture tuning switch corresponding to the first antenna, and a conductive state of an aperture tuning switch corresponding to the second antenna.

That is, the first parameter set is the on state of the aperture tuning switch in a state where the antenna transmits and receives signals simultaneously. The second parameter set refers to a set of tuning parameters of all aperture tuning switches on the electronic device when each antenna of the plurality of antennas receives only signals (corresponding to the second operating state) in the current operating frequency band.

Wherein the TAS information is used to indicate the antenna that transmitted the signal at the current time.
