The method for adjusting the antenna performance according to the embodiment of the present invention can adjust the antenna 5 to restore the performance of the antenna 5 to the state before the extension device is not installed, as shown in fig. 1, when the extension device is installed on the electronic device 1 (such as a mobile phone, a tablet computer, or a notebook computer) and the extension device affects the transmission and reception of the signal of the antenna 5 of the electronic device 1, and the method for adjusting the antenna performance includes the following steps:
s1, detecting whether an expansion device is connected to the electronic equipment 1, wherein the expansion device can be detachably connected with the electronic equipment 1 directly; when the expansion device is connected with the electronic equipment 1, the expansion device is positioned on a first side surface of the electronic equipment 1 and at least covers part of the first side surface; the extension means is used to enhance a function of the electronic device 1. The expansion device is an additional device detachably connected to the electronic device 1, for example, detachably connected to and assembled on a rear case of a mobile phone, and additionally installed on one side of the tablet computer, and is used for enhancing at least one function of the electronic device 1, for example, prolonging power supply of the electronic device 1, enhancing a camera shooting function of the electronic device 1, enhancing a sound effect of the electronic device 1, and the like. The extension device is located on the first side of the electronic device 1 and covers at least a portion of the first side, and the specific definition of the first side may be set according to different types of electronic devices 1 and corresponding extension devices, for example, the electronic device 1 is a mobile phone, the first side of the electronic device is a rear cover, and the extension device may be mounted on the rear cover and cover most of the area of the rear cover, so as to increase the power reserve of the mobile phone. In this embodiment, it is necessary to first detect whether the electronic device 1 is connected to the expansion device, and if the electronic device 1 is not connected to the expansion device, the performance of the antenna 5 of the electronic device 1 does not need to be adjusted, otherwise, other adjustment steps may be performed to ensure the performance of the antenna 5, thereby ensuring that the function of the electronic device 1 is not weakened.
S2, detecting whether the characteristic of the antenna 5 of the electronic device 1 changes based on the detection result of checking the connection of the expansion device. When the extension device is attached to the electronic device 1, the performance of the antenna 5 of the electronic device 1 for transmitting and receiving signals may or may not be affected. For example, the extension device made of wood or plastic material added to the electronic device 1 will not affect the performance of the antenna 5, while the extension device made of other metal material will affect the performance of the antenna 5. Therefore, if an extension device is connected to the electronic device 1, it is necessary to detect whether the characteristics of the antenna 5 of the electronic device 1 are changed, if the characteristics are not changed, that is, the same characteristics as those of the electronic device without the extension device, it is not necessary to adjust the performance of the antenna 5, and if the characteristics of the antenna 5 of the electronic device 1 are changed, the characteristics of the antenna 5 can be adjusted to ensure the performance of the antenna 5.
S3, based on the detection result of the change of the characteristic of the antenna 5 of the electronic device 1, the characteristic of the antenna 5 is adjusted by the Tuner (Tuner) to improve the performance of the antenna 5 for transmitting or receiving signals consistent with the performance of the antenna 5 for transmitting or receiving signals of the electronic device 1 before the extension apparatus is connected. The tuner may be application software or hardware loaded with software, and has a tuning function, when the extension device is connected to the electronic device 1 and the characteristics of the antenna 5 have changed, the tuning function can be activated or the tuner is started to operate, and the tuner can improve the performance of the antenna 5 for transmitting or receiving signals through the adjustment of software and/or hardware, so that the performance of the antenna 5 is consistent with the performance of the antenna 5 for transmitting or receiving signals of the electronic device 1 before the extension device is connected, and it is ensured that the functions or functions of the electronic device 1 related to the antenna 5 are not reduced, for example, the communication performance of a mobile phone is not reduced because the extension device is added.
In an embodiment of the present invention, as shown in fig. 4, the method for adjusting the performance of the antenna 5 further includes the following steps (e.g., after adjusting the characteristics of the antenna 5): the ID information of the extension device and the adjusted characteristic parameters of the antenna 5 are recorded so that the tuner adjusts the antenna 5 directly based on the recorded characteristic parameters for the extension device when the extension device is connected again. The ID information of the extension device is a unique identifier of the extension device, and the extension device corresponding to the ID information can be found according to the unique ID information, and the effect of each extension device on the same electronic apparatus 1 is different, even if the same type of extension device has different effects, in this embodiment, the ID information of the extension device connected to the electronic apparatus 1 needs to be recorded, so that the extension device can be identified when being connected to the electronic apparatus 1 again. In addition, it is also necessary to record characteristic parameters of the antenna 5 adjusted for the extension device after adjustment, and in conjunction with fig. 4, particularly, the characteristic parameters used in the first adjustment are associated with or mapped to ID information of the extension device and then stored, for example, different characteristic parameters may be stored as a first mode, a second mode, a third mode, or the like, so that when the electronic device 1 connects the extension device again, the tuner directly adjusts the antenna 5 based on the recorded characteristic parameters of the antenna 5 connected for the extension device, for example, directly calls the first mode, the second mode, or the third mode, so that the tuner adjusts the antenna 5 using the above modes, thereby saving processing time and improving adjustment efficiency.
In an embodiment of the present invention, as shown in fig. 2, the antenna performance adjusting method further includes the following steps:
s4, detecting Total Radiated Power (TRP) of the antenna 5 in a plurality of frequency bands. Specifically, the antenna 5 has a plurality of frequency bands, each frequency band having its total radiated power, which means the integral value of the radio frequency radiated power of the electronic device 1 on a spatial three-dimensional spherical surface, reflecting the emission characteristics of the electronic device 1 in all directions. The effect of the spreading means on the antenna 5 may be reflected in the total radiated power in one or more frequency bands, e.g. the total radiated power in a frequency band decreases. It is therefore necessary to detect the total radiated power in each frequency band of the antenna 5 in order to determine which frequency band or bands are affected by the extension device.
S5, determining the frequency band affected by the extension device by comparing the total radiated power with the original power of the antenna 5 in the same frequency band when the electronic device 1 is not connected to the extension device. In particular, the total radiated power of each frequency band may be compared with the original power of the antenna 5 in the same frequency band, where the original power is the power of the wire when the electronic device 1 is not connected to an extension device. The comparison process may be sequential comparison or may be that the frequency band susceptible to be affected is first selected for comparison, and the frequency band affected by the extension device (which may be one or more) is determined, so as to adjust the characteristics of the antenna 5 for the affected frequency band.
In an embodiment of the present invention, the step of adjusting the characteristic of the antenna 5 through the tuner based on the detection result of the change of the characteristic of the antenna 5 of the electronic device 1 includes the following steps: at least one characteristic parameter (operating parameter) of the antenna 5 is tuned with reference to the original power using a tuner to adjust the total radiated power in the frequency band affected by the extension device, so as to counteract the performance of the antenna 5 to transmit or receive signals affected by the extension device. Specifically, when the tuner is used to adjust the performance of the antenna 5, the characteristic parameter of the antenna 5 may be adjusted to achieve the purpose of adjusting the performance of the antenna 5, for example, an efficiency parameter, a linearity parameter, an input power parameter, and the like of the antenna 5 may be adjusted, and when the adjustment needs to adjust the total radiation power of the affected frequency band with reference to the original power, specifically, when the adjustment is performed, in one embodiment, the adjustment may be performed according to the priority of the characteristic parameter, for example, the characteristic parameter with a higher priority is adjusted first, and then the characteristic parameter with a lower priority is adjusted; in another embodiment, a plurality of adjustment services may be preset, each adjustment service involving an adjustment method for a plurality of characteristic parameters, and one adjustment service is selected during adjustment, so as to adjust the plurality of characteristic parameters, so as to adjust the total radiation power of the antenna 5 in the affected frequency band, thereby counteracting the influence of the extension device on the performance of the transmission or reception signal of the antenna 5.
In an embodiment of the present invention, as shown in fig. 3, the antenna performance adjusting method further includes the following steps:
s6, detecting the connection status of the expansion device and the electronic apparatus 1. The expansion device is detachably connected to the electronic device 1, and can be installed when in use and detached from the electronic device 1 when not in use. The connection state indicates the connection relationship between the expansion device and the electronic device 1, and further indicates whether the user continues to use the expansion device. The connection state may be detected at predetermined time intervals during the detection, or may be detected when the connection state between the expansion device and the electronic device 1 changes, so as to determine whether the expansion device is still connected to the electronic device 1.
S7, when the extension device is detached from the electronic device 1, the tuner is used to tune the total radiated power in the frequency band affected by the extension device to the original power. When the extension device is detached from the electronic device 1, the influence of the extension device on the antenna 5 disappears, and at this moment, the total radiation power of the antenna 5 in the corresponding frequency band also changes due to the sudden disappearance of the image of the extension device, and the change may cause the characteristic abnormality of the antenna 5, thereby affecting the function of the electronic device 1 related to the antenna 5, so that the total radiation power of the frequency band affected by the extension device needs to be adjusted to the original power by using a tuner, thereby ensuring that the antenna 5 recovers to the original (or factory) characteristic, and enabling the electronic device 1 to normally operate.
An embodiment of the present invention further provides an electronic device 1, where the electronic device 1 (such as a mobile phone, a tablet computer, or a notebook computer, and the like) can adjust an antenna 5 of the electronic device 1 when an extension device is installed on the electronic device 1 and the extension device affects transmission and reception of a signal of the antenna 5, so that performance of the antenna 5 is restored to a state before the extension device is not installed, as shown in fig. 5, the electronic device 1 includes a connection detection module 2, a detection module 3, and an adjustment module 4.
The connection detection module 2 is configured to detect whether the electronic device 1 is connected with an expansion device, wherein the expansion device can be detachably connected with the electronic device 1; when the expansion device is connected with the electronic device 1, the expansion device is located on the first side surface of the electronic device 1 and at least covers a part of the first side surface; the expansion means is used to enhance a function of the electronic device 1. The expansion device is an additional device detachably connected to the electronic device 1, for example, detachably connected to and assembled on a rear case of a mobile phone, and additionally installed on one side of the tablet computer, and is used for enhancing at least one function of the electronic device 1, for example, prolonging power supply of the electronic device 1, enhancing a camera shooting function of the electronic device 1, enhancing a sound effect of the electronic device 1, and the like. The extension device is located on the first side of the electronic device 1 and covers at least a portion of the first side, and the specific definition of the first side may be set according to different types of electronic devices 1 and corresponding extension devices, for example, the electronic device 1 is a mobile phone, the first side of the electronic device is a rear cover, and the extension device may be mounted on the rear cover and cover most of the area of the rear cover, so as to increase the power reserve of the mobile phone. In this embodiment, the connection detection module 2 is required to first detect whether the electronic device 1 is connected to the expansion device, if the electronic device 1 is not connected to the expansion device, the performance of the antenna 5 of the electronic device 1 does not need to be adjusted, otherwise, other adjustment steps may be performed to ensure the performance of the antenna 5, thereby ensuring that the function of the electronic device 1 is not weakened.
The detection module 3 is configured to detect whether the characteristic of the antenna 5 of the electronic apparatus 1 is changed based on the detection result of checking the connection of the expansion device. When the extension device is attached to the electronic device 1, the performance of the antenna 5 of the electronic device 1 for transmitting and receiving signals may or may not be affected. For example, the extension device made of wood or plastic material added to the electronic device 1 will not affect the performance of the antenna 5, while the extension device made of other metal material will affect the performance of the antenna 5. Therefore, if an extension device is connected to the electronic device 1, the detection module 3 needs to detect whether the characteristics of the antenna 5 of the electronic device 1 are changed, if the characteristics are not changed, that is, the characteristics are the same as those of the antenna 5 without the extension device, it is not necessary to adjust the performance of the antenna 5, and if the detection module 3 detects that the characteristics of the antenna 5 of the electronic device 1 are changed, the characteristics of the antenna 5 can be adjusted to ensure the performance of the antenna 5.
The adjusting module 4 is configured to adjust the characteristic of the antenna 5 of the electronic device 1 through a Tuner (Tuner) of the electronic device 1 based on the detection result of the change of the characteristic of the antenna 5 of the electronic device 1, so as to improve the performance of the antenna 5 for transmitting or receiving signals to be consistent with the performance of the antenna 5 for transmitting or receiving signals of the electronic device 1 before the extension apparatus is connected. The tuner may be application software or hardware loaded with software, and has a tuning function, when the extension device is connected to the electronic device 1 and the characteristics of the antenna 5 have changed, the adjusting module 4 can activate the adjusting function or start the tuner to operate, and the tuner can improve the performance of the antenna 5 for transmitting or receiving signals through adjustment of software and/or hardware, so that the performance of the antenna 5 is consistent with the performance of the antenna 5 of the electronic device 1 for transmitting or receiving signals before the extension device is connected, and it is ensured that the functions or functions related to the antenna 5 of the electronic device 1 are not reduced, for example, the communication performance of a mobile phone is not reduced because the extension device is added.
In one embodiment of the present invention, as shown in fig. 4, the electronic device 1 further includes a storage module configured to record the ID information of the extension apparatus and the adjusted characteristic parameters of the antenna 5, so that when the extension apparatus is connected again, the tuner adjusts the ID information and the adjusted characteristic parameters of the antenna 5 directly based on the recorded characteristic parameters of the antenna 5 connected to the extension apparatus. The ID information of the extension device is a unique identifier of the extension device, and the extension device corresponding to the ID information can be found according to the unique ID information, the effect of each extension device on the same electronic apparatus 1 is different, even if the extension devices of the same type have different influences, in this embodiment, the storage module needs to record the ID information of the extension device connected to the electronic apparatus 1, so that the storage module can identify the extension device when the extension device is subsequently connected to the electronic apparatus 1 again. In addition, the storage module needs to record characteristic parameters of the antenna 5 adjusted for the extension device after adjustment, and in conjunction with fig. 4, particularly, the characteristic parameters used in the first adjustment are associated with or mapped to ID information of the extension device before being stored, for example, the storage module may store different characteristic parameters as a first mode, a second mode, a third mode, or the like, so that when the electronic device 1 connects the extension device again, the tuner directly adjusts the antenna 5 based on the recorded characteristic parameters of the antenna 5 connected for the extension device, for example, directly calls the first mode, the second mode, or the third mode, so that the tuner adjusts the antenna 5 using the above modes, thereby saving processing time and improving adjustment efficiency.
In an embodiment of the present invention, the detecting module 3 is further configured to detect Total Radiated Power (TRP) of the antenna 5 in a plurality of frequency bands, and determine the frequency band affected by the expansion device by comparing the total radiated power with original power of the antenna 5 in the same frequency band when the expansion device is not connected to the electronic device 1.
Specifically, the antenna 5 has a plurality of frequency bands, each frequency band having its total radiated power, which means the integral value of the radio frequency radiated power of the electronic device 1 on a spatial three-dimensional spherical surface, reflecting the emission characteristics of the electronic device 1 in all directions. The effect of the spreading means on the antenna 5 may be reflected in the total radiated power in one or more frequency bands, e.g. the total radiated power in a frequency band decreases. The detection module 3 needs to detect the total radiated power of each frequency band of the antenna 5, so as to determine which frequency band or bands are affected by the extension device. The total radiated power in each frequency band can be compared in determining the frequency band affected by the extension means with the original power of the antenna 5 in the same frequency band, where the original power is the power of the wire when the electronic device 1 is not connected to the extension means. The comparison process may be sequential comparison or may be that the frequency band susceptible to be affected is first selected for comparison, and the frequency band affected by the extension device (which may be one or more) is determined, so as to adjust the characteristics of the antenna 5 for the affected frequency band.
