[0017] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0018] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present application. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0019] like Figures 2 to 5 As shown, the electronic device includes: a first antenna 10, a second antenna 20, a third antenna 30, a fourth antenna 40 and a controller.

[0020] The first antenna 10, second antenna 20, third antenna 30, and fourth antenna 40 are all located on the surface of the electronic device. A controller is located within the electronic device and is electrically connected to the controller. The first antenna 10, second antenna 20, third antenna 30, and fourth antenna 40 are spaced apart. The controller controls a target number of antennas from the first antenna 10, second antenna 20, third antenna 30, and fourth antenna 40 to form at least one antenna cluster (the target number is 2 or 3), so that the antenna cluster can coordinate with the remaining antennas for angle measurement.

[0021] In an embodiment of the present application, the first antenna 10, the second antenna 20, the third antenna 30, and the fourth antenna 40 are spaced apart, and the first antenna 10, the second antenna 20, the third antenna 30, and the fourth antenna 40 are all electrically connected to a controller, so that the controller can control a target number of antennas among the first antenna 10, the second antenna 20, the third antenna 30, and the fourth antenna 40 to form at least one antenna cluster, and the angle measurement can be performed in coordination with the remaining antennas by the antenna cluster, thereby improving the angle measurement performance of the electronic device.

[0022] It should be noted that in the embodiment of the present application, the lines connecting the first antenna 10, the second antenna 20, the third antenna 30, and the fourth antenna 40 in sequence form a quadrilateral. In this case, the first antenna 10, the second antenna 20, the third antenna 30, and the fourth antenna 40 correspond to the four vertices of the quadrilateral. In addition, the quadrilateral can be a parallelogram, a rectangle, a square, a rhombus, or an irregular quadrilateral with four sides. The specific type of the quadrilateral formed by the lines connecting the first antenna 10, the second antenna 20, the third antenna 30, and the fourth antenna 40 in sequence in the embodiment of the present application is not limited in this embodiment.

[0023] For example, Figure 2 As shown in FIG, the quadrilateral formed by the lines connecting the first antenna 10, the second antenna 20, the third antenna 30 and the fourth antenna 40 in sequence is a rectangle. Figure 3 As shown in FIG, the quadrilateral formed by the lines connecting the first antenna 10, the second antenna 20, the third antenna 30 and the fourth antenna 40 in sequence is an irregular quadrilateral. Figure 4 As shown, the quadrilateral formed by the lines connecting the first antenna 10 , the second antenna 20 , the third antenna 30 and the fourth antenna 40 in sequence is an irregular quadrilateral.

[0024] In addition, in the embodiment of the present application, the first antenna 10, the second antenna 20, the third antenna 30, and the fourth antenna 40 can all be located on the back of the electronic device. Of course, the first antenna 10, the second antenna 20, the third antenna 30, and the fourth antenna 40 can also all be located on the front of the electronic device. This is not limited in the embodiment of the application.

[0025] In addition, in related technologies, such as Figure 1As shown, the electronic device includes a first antenna 10, a second antenna 20, and a third antenna 30. The electronic device uses the first antenna 10, the second antenna 20, and the third antenna 30 to perform angle measurement. During angle measurement, the first antenna 10 and the second antenna 20 are used for horizontal angle measurement, while the second antenna 20 and the third antenna 30 are used for vertical angle measurement. After the electronic device performs horizontal and vertical angle measurements, it can accurately determine the angular position of the object under test relative to the electronic device. During horizontal angle measurement, after the signal emitted by the first antenna 10 is transmitted to the object under test, a first distance between the first antenna 10 and the object under test can be determined. Similarly, a second distance between the second antenna 20 and the object under test can also be determined. Based on the first and second distances, a first angle between the object under test and the electronic device can be determined. During vertical angle measurement, after the signal emitted by the second antenna 20 is transmitted to the object under test, a second distance between the second antenna 20 and the object under test can be determined. Similarly, a third distance between the third antenna 30 and the object under test can also be determined. Based on the second and third distances, a second angle between the object under test and the electronic device can be determined. Based on the first and second angles, the angular position of the object to be measured relative to the electronic device can be accurately located. In addition, in the related art, when measuring horizontal angles, the first antenna 10 and the second antenna 20 need to work together, and when measuring vertical angles, the second antenna 20 and the third antenna 30 need to work together. However, the first antenna 10, the second antenna 20, and the third antenna 30 are each supported by only a single antenna, resulting in high requirements for the first antenna 10, the second antenna 20, and the third antenna 30. Specifically, the requirements for the uniformity of the first antenna 10 and the second antenna 20, the lobe width of the radiation pattern, etc. are high. Once the radiation performance of any of the first antenna 10, the second antenna 20, and the third antenna 30 is poor, it will greatly affect the angle measurement accuracy of the electronic device.

[0026] In an embodiment of the present application, the electronic device includes a first antenna 10, a second antenna 20, a third antenna 30, and a fourth antenna 40, which is equivalent to adding a fourth antenna 40. Furthermore, the lines connecting the first antenna 10, the second antenna 20, the third antenna 30, and the fourth antenna 40 are enclosed in a quadrilateral, so that two or three of the first antenna 10, the second antenna 20, the third antenna 30, and the fourth antenna 40 can be clustered, thereby performing angle measurement using the antenna cluster and the remaining antennas. After forming an antenna cluster from two or three antennas, the characteristics of the antenna cluster can be flexibly adjusted by adjusting the amplitude and phase excitation of each antenna in the antenna cluster to better meet requirements for the antenna cluster's lobe width, uniformity, consistency, and the like, thereby improving the angle measurement performance of the electronic device.

[0027] In addition, in the embodiment of the present application, the electronic device may further include a fifth antenna 50, which is located on the side of the electronic device.

[0028] In addition, in the embodiment of the present application, when the target number is different, the controller controls the target number of antennas among the first antenna 10, the second antenna 20, the third antenna 30, and the fourth antenna 40 to form at least one antenna cluster, so that the antenna cluster and the remaining antennas cooperate to perform angle measurement. The implementation method is also different, which is specifically described in the following ways:

[0029] Method (1): The target number is 2, and the controller controls the target number of antennas among the first antenna 10, the second antenna 20, the third antenna 30 and the fourth antenna 40 to form at least one antenna cluster, so that the antenna cluster and the remaining antennas can cooperate to measure angles. The implementation method can be: the controller controls any two antennas among the first antenna 10 to the fourth antenna 40 to form a first antenna cluster, and controls the remaining two antennas to form a second antenna cluster, so that the first antenna cluster and the second antenna cluster can cooperate to measure angles.

[0030] When the controller controls any two antennas from the first antenna 10 to the fourth antenna 40 to form a first antenna cluster, and controls the remaining two antennas to form a second antenna cluster, it is equivalent to collaboratively measuring angles through the two antenna clusters. Compared with the related art in which collaborative angle measurement is performed through two single antennas, the antenna cluster in the present application includes two antennas, which is equivalent to increasing the number of antennas for angle measurement, thereby improving the angle measurement performance of the electronic device.

[0031] For example, in the related art, horizontal angle measurement is performed collaboratively by the first antenna 10 and the second antenna 20, while in the present application, horizontal angle measurement is performed collaboratively by the first antenna cluster and the second antenna cluster. Compared with the related art, the number of antennas included in the first antenna cluster in the present application is significantly greater than the single first antenna 10 in the related art, and the number of antennas included in the second antenna cluster is significantly greater than the single second antenna 20 in the related art.

[0032] In addition, in an embodiment of the present application, the controller controls any two antennas from the first antenna 10 to the fourth antenna 40 to form a first antenna cluster, and controls the remaining two antennas to form a second antenna cluster, so that the first antenna cluster and the second antenna cluster can cooperate to perform angle measurement. The implementation method can be: the controller controls the first antenna 10 and the second antenna 20 to form a first target antenna cluster, and controls the third antenna 30 and the fourth antenna 40 to form a second target antenna cluster, so that the first target antenna cluster and the second target antenna cluster perform first-dimension angle measurement; the controller controls the first antenna 10 and the fourth antenna 40 to form a third target antenna cluster, and controls the second antenna 20 and the third antenna 30 to form a fourth target antenna cluster, so that the third target antenna cluster and the fourth target antenna cluster perform second-dimension angle measurement to complete the angle measurement.

[0033] When the first antenna 10 and the second antenna 20 are controlled to form a first target antenna cluster, and the third antenna 30 and the fourth antenna 40 are controlled to form a second target antenna cluster, at this time, the first target antenna cluster and the second target antenna cluster are used to collaboratively perform first-dimension angle measurement. If the first-dimension angle measurement is horizontal angle measurement, the horizontal angle measurement performance of the first target antenna cluster and the second target antenna cluster in the embodiment of the present application is better than that of the first antenna 10 and the second antenna 20 in the related art. When the first antenna 10 and the fourth antenna 40 are controlled to form a third target antenna cluster, and the second antenna 20 and the third antenna 30 are controlled to form a fourth target antenna cluster, at this time, the second-dimension angle measurement is performed collaboratively by the third target antenna cluster and the fourth target antenna cluster. If the second-dimension angle measurement is vertical angle measurement, the vertical angle measurement performance of the third target antenna cluster and the fourth target antenna cluster in the embodiment of the present application is better than that of the second antenna 20 and the third antenna 30 in the related art.

[0034] Furthermore, after controlling the first antenna 10 and the second antenna 20 to form a first target antenna cluster, the characteristics of the first target antenna cluster can be flexibly adjusted by adjusting the amplitude and phase excitation of each of the first antenna 10 and the second antenna 20, so that the first target antenna cluster better meets the requirements for the lobe width, uniformity, and consistency of the angle measurement antenna. Similarly, controlling the third antenna 30 and the fourth antenna 40 to form a second target antenna cluster, controlling the first antenna 10 and the fourth antenna 40 to form a third target antenna cluster, and controlling the second antenna 20 and the third antenna 30 to form a fourth target antenna cluster can all better meet the requirements for the lobe width, uniformity, and consistency of the angle measurement antenna.

[0035] It should be noted that the first dimension angle measurement can be horizontal angle measurement, and of course it can also be angle measurement in other directions. The second dimension angle measurement can be vertical angle measurement, and of course it can also be angle measurement in other directions. It is only necessary that the first dimension angle measurement and the second dimension angle measurement are not measured in the same direction, that is, the angle measurement direction of the first dimension angle measurement intersects with the angle measurement direction of the second dimension angle measurement.

[0036] In addition, in some embodiments, the controller is configured to adjust the incident wave excitation of the first antenna 10 and the incident wave excitation of the second antenna 20 to obtain a first radiation pattern of the first target antenna cluster; adjust the incident wave excitation of the third antenna 30 and the incident wave excitation of the fourth antenna 40 to obtain a second radiation pattern of the second target antenna cluster, wherein the deviation between the second radiation pattern and the first radiation pattern is less than a preset deviation threshold. The controller is further configured to adjust the incident wave excitation of the first antenna 10 and the incident wave excitation of the fourth antenna 40 to obtain a third radiation pattern of the third target antenna cluster; adjust the incident wave excitation of the second antenna 20 and the incident wave excitation of the fourth antenna 40 to obtain a fourth radiation pattern of the fourth target antenna cluster, wherein the deviation between the third radiation pattern and the fourth radiation pattern is less than a preset deviation threshold.

[0037] Among them, after controlling the first antenna 10 and the second antenna 20 to form the first target antenna cluster, and controlling the third antenna 30 and the fourth antenna 40 to form the second target antenna cluster, the consistency of the radiation pattern between the first target antenna cluster and the second target antenna cluster has an important influence on the angle measurement accuracy. At this time, the incident wave excitation of the first target antenna cluster can be optimized and adjusted to achieve a change in the radiation pattern of the first target antenna cluster, and at the same time, the incident wave excitation of the second target antenna cluster can be optimized and adjusted to achieve a change in the radiation pattern of the second target antenna cluster. In the process of optimizing and adjusting the incident wave excitation of the first target antenna cluster and the incident wave excitation of the second target antenna cluster, the deviation between the radiation pattern of the first target antenna cluster and the radiation pattern of the second target antenna cluster is less than a preset deviation threshold, which can make the angle measurement accuracy of the first target antenna cluster and the second target antenna cluster higher when performing angle measurement in collaboration. Among them, when adjusting the radiation pattern of the first target antenna cluster, the radiation pattern of the first target antenna cluster can be adjusted by adjusting the incident wave excitation of the first antenna 10 and the second antenna 20. Similarly, when adjusting the radiation pattern of the second target antenna cluster, the radiation pattern of the second target antenna cluster can be adjusted by adjusting the incident wave excitation of the third antenna 30 and the fourth antenna 40 .

[0038] In addition, after controlling the first antenna 10 and the fourth antenna 40 to form a third target antenna cluster and controlling the second antenna 20 and the third antenna 30 to form a fourth target antenna cluster, the consistency of the radiation pattern between the third target antenna cluster and the fourth target antenna cluster has an important influence on the angle measurement accuracy. At this time, the incident wave excitation of the third target antenna cluster can be optimized and adjusted to achieve a change in the radiation pattern of the third target antenna cluster, and at the same time, the incident wave excitation of the fourth target antenna cluster can be optimized and adjusted to achieve a change in the radiation pattern of the fourth target antenna cluster. In the process of optimizing and adjusting the incident wave excitation of the third target antenna cluster and the incident wave excitation of the fourth target antenna cluster, the deviation between the radiation pattern of the third target antenna cluster and the radiation pattern of the fourth target antenna cluster is less than a preset deviation threshold, which can make the angle measurement accuracy of the third target antenna cluster and the fourth target antenna cluster higher when performing angle measurement in collaboration. Among them, when adjusting the radiation pattern of the third target antenna cluster, the radiation pattern of the third target antenna cluster can be adjusted by adjusting the incident wave excitation of the first antenna 10 and the fourth antenna 40. Similarly, when adjusting the radiation pattern of the fourth target antenna cluster, the radiation pattern of the fourth target antenna cluster can be adjusted by adjusting the incident wave excitation of the second antenna 20 and the third antenna 30 .

[0039] In addition, in some embodiments, the controller is used to adjust the incident wave excitation of the first antenna 10 and the incident wave excitation of the second antenna 20 to obtain a first target radiation pattern of the first target antenna cluster, and the lobe width of the first target radiation pattern is the target width; adjust the incident wave excitation of the third antenna 30 and the incident wave excitation of the fourth antenna 40 to obtain a second target radiation pattern of the second target antenna cluster, and the lobe width of the second target radiation pattern is the target width. The controller is also used to adjust the incident wave excitation of the first antenna 10 and the incident wave excitation of the fourth antenna 40 to obtain a third target radiation pattern of the third target antenna cluster, and the lobe width of the third target radiation pattern is the target width; adjust the incident wave excitation of the third antenna 30 and the incident wave excitation of the fourth antenna 40 to obtain a fourth target radiation pattern of the fourth target antenna cluster, and the lobe width of the fourth target radiation pattern is the target width.

[0040] The radiation coverage of the angle measurement antenna, i.e., the lobe width of the radiation pattern, directly affects the angle measurement coverage of the antenna system. Therefore, the incident wave excitation of the first antenna 10 and the incident wave excitation of the second antenna 20 can be adjusted to adjust the lobe width of the first target radiation pattern of the first target antenna cluster. When the lobe width is the maximum width of the first target radiation pattern, the lobe width is the target width, and the radiation coverage of the first target antenna cluster is maximized. Similarly, the incident wave excitation of the third antenna 30 and the incident wave excitation of the fourth antenna 40 can be adjusted to adjust the lobe width of the second target radiation pattern of the second target antenna cluster. When the lobe width is the maximum width of the second target radiation pattern, the lobe width is the target width, and the radiation coverage of the second target antenna cluster is maximized. When the radiation coverage of the first target antenna cluster is maximized and the radiation coverage of the second target antenna cluster is maximized, the coverage of the first target antenna cluster and the second target antenna cluster when performing collaborative angle measurement can be maximized.

[0041] In addition, the incident wave excitation of the first antenna cluster and the incident wave excitation of the fourth antenna 40 can also be adjusted to adjust the lobe width of the third target radiation pattern of the third target antenna cluster. When the lobe width is the maximum width of the third target radiation pattern, the lobe width is the target width, and the radiation coverage of the third target antenna cluster is maximized. Similarly, the incident wave excitation of the second antenna cluster and the incident wave excitation of the third antenna 30 can be adjusted to adjust the lobe width of the third target radiation pattern of the third target antenna cluster. When the lobe width is the maximum width of the second target radiation pattern, the lobe width is the target width, and the radiation coverage of the third target antenna cluster is maximized. When the radiation coverage of the third target antenna cluster is maximized and the radiation coverage of the fourth target antenna cluster is maximized, the coverage of the third target antenna cluster and the fourth target antenna cluster when performing collaborative angle measurement can be maximized.

[0042] Method (2): The target number is 2, and the controller controls the target number of antennas among the first antenna 10, the second antenna 20, the third antenna 30 and the fourth antenna 40 to form an antenna cluster, so that the antenna cluster and the remaining antennas can cooperate to perform angle measurement. The implementation method can be: the controller controls the first antenna 10 and the second antenna 20 to form a fourth antenna cluster 100, so that the fourth antenna cluster 100 and the third antenna 30 perform third-dimensional angle measurement, and the fourth antenna cluster 100 and the fourth antenna 40 perform fourth-dimensional angle measurement to complete the angle measurement.

[0043] When the first antenna 10 and the second antenna 20 are controlled to form the fourth antenna cluster 100, the fourth antenna cluster 100 and the third antenna 30 collaborate to perform third-dimensional angle measurement. If the third-dimensional angle measurement is horizontal, the fourth antenna cluster 100 in the embodiment of the present application has better horizontal angle measurement performance than the first antenna 10 and the second antenna 20 in the related art that collaborate to perform horizontal angle measurement. In addition, when the fourth antenna cluster 100 and the fourth antenna 40 collaborate to perform fourth-dimensional angle measurement, if the fourth-dimensional angle measurement is vertical, the fourth antenna cluster 100 in the embodiment of the present application has better vertical angle measurement performance than the second antenna 20 and the third antenna 30 in the related art that collaborate to perform vertical angle measurement.

[0044] In addition, after controlling the first antenna 10 and the second antenna 20 to form the fourth antenna cluster 100, the characteristics of the fourth antenna cluster 100 can be flexibly adjusted by adjusting the amplitude and phase excitation of each antenna in the first antenna 10 and the second antenna 20, so that the fourth antenna cluster 100 can better meet the requirements for the lobe width, uniformity, consistency, etc. of the angle measurement antenna.

[0045] It should be noted that the third dimension angle measurement can be horizontal angle measurement, and of course it can also be angle measurement in other directions. The fourth dimension angle measurement can be vertical angle measurement, and of course it can also be angle measurement in other directions. It is only necessary that the third dimension angle measurement and the fourth dimension angle measurement are not measured in the same direction, that is, the angle measurement direction of the third dimension angle measurement intersects with the angle measurement direction of the fourth dimension angle measurement.

[0046] In addition, in an embodiment of the present application, the controller can also control the first antenna 10 and the fourth antenna 40 to form a fourth antenna cluster 100. At this time, the fourth antenna cluster 100 and the second antenna 20 perform third-dimensional angle measurement, and the fourth antenna cluster 100 and the third antenna 30 perform fourth-dimensional angle measurement to complete the angle measurement. Of course, the controller can also control the second antenna 20 and the third antenna 30 to form a fourth antenna cluster 100. At this time, the fourth antenna cluster 100 and the first antenna 10 perform third-dimensional angle measurement, and the fourth antenna cluster 100 and the fourth antenna 40 perform fourth-dimensional angle measurement to complete the angle measurement. The controller can also control the third antenna 30 and the fourth antenna 40 to form a fourth antenna cluster 100. At this time, the fourth antenna cluster 100 and the first antenna 10 perform third-dimensional angle measurement, and the fourth antenna cluster 100 and the third antenna 30 perform fourth-dimensional angle measurement to complete the angle measurement.

[0047] For example, Figure 5 As shown, the fourth antenna cluster 100 cooperates with the third antenna 30 to perform angle measurement in the third dimension, and the fourth antenna cluster 100 cooperates with the fourth antenna 40 to perform angle measurement in the fourth dimension.

[0048] Method (3): The target number is 3, and the controller controls the target number of antennas among the first antenna 10, the second antenna 20, the third antenna 30 and the fourth antenna 40 to form at least one antenna cluster, so that the antenna cluster and the remaining antennas can cooperate to perform angle measurement. The implementation method can be: the controller controls the first antenna 10, the second antenna 20 and the fourth antenna 40 to form a fifth antenna cluster, so that the fifth antenna cluster and the third antenna 30 perform angle measurement in the fifth dimension, and also controls the first antenna 10, the second antenna 20 and the third antenna 30 to form a sixth antenna cluster, so that the sixth antenna cluster and the fourth antenna 40 perform angle measurement in the sixth dimension to complete the angle measurement.

[0049] When the first antenna 10, the second antenna 20, and the fourth antenna 40 are controlled to form a fifth antenna cluster, the fifth antenna cluster can be used in conjunction with the third antenna 30 to perform fifth-dimensional angle measurement. If the fifth-dimensional angle measurement is horizontal angle measurement, the fifth antenna cluster in the embodiment of the present application has better horizontal angle measurement performance than the first antenna 10 and the second antenna 20 in the related art that perform horizontal angle measurement in conjunction. When the first antenna 10, the second antenna 20, and the third antenna 30 are controlled to form a second angle measurement antenna cluster, the sixth antenna cluster can be used in conjunction with the fourth antenna 40 to perform sixth-dimensional angle measurement. If the sixth-dimensional angle measurement is vertical angle measurement, the sixth antenna cluster in the embodiment of the present application has better vertical angle measurement performance than the second antenna 20 and the third antenna 30 in the related art that perform vertical angle measurement in conjunction.

[0050] In addition, after controlling the first antenna 10, the second antenna 20 and the fourth antenna 40 to form the fifth antenna cluster, the characteristics of the fifth antenna cluster can be flexibly adjusted by adjusting the amplitude and phase excitation of each antenna in the first antenna 10, the second antenna 20 and the fourth antenna 40, so that the fifth antenna cluster can better meet the requirements for the lobe width, uniformity, consistency, etc. of the angle measurement antenna.

[0051] It should be noted that the fifth dimension angle measurement can be horizontal angle measurement, and of course it can also be angle measurement in other directions. The sixth dimension angle measurement can be vertical angle measurement, and of course it can also be angle measurement in other directions. It is only necessary that the fifth dimension angle measurement and the sixth dimension angle measurement are not measured in the same direction, that is, the angle measurement direction of the fifth dimension angle measurement intersects with the angle measurement direction of the sixth dimension angle measurement.

[0052] In addition, in some embodiments, the electronic device further has a first angle measurement mode and a second angle measurement mode. The angle measurement accuracy of the first angle measurement mode is greater than that of the second angle measurement mode, and the angle measurement coverage of the first angle measurement mode is smaller than that of the second angle measurement mode. The controller is configured to control a target number of antennas from the first antenna 10, the second antenna 20, the third antenna 30, and the fourth antenna 40 to form a fifth antenna cluster 50. The fifth antenna cluster 50 and the remaining antennas correspond to the first angle measurement mode. The controller is also configured to control a target number of antennas from the first antenna 10, the second antenna 20, the third antenna 30, and the fourth antenna 40 to form an eighth antenna cluster. The eighth antenna cluster and the remaining antennas correspond to the second angle measurement mode. When the electronic device is in the second angle measurement mode and detects an object to be measured, the controller switches the second angle measurement mode to the first angle measurement mode.

[0053] When the fifth antenna 50 cluster and the remaining antennas correspond to the first angle measurement mode, and the eighth antenna cluster and the remaining antennas correspond to the second side angle mode, when measuring angles using the electronic device, the second angle measurement mode can be used first, that is, the eighth antenna cluster and the remaining antennas can be controlled to measure angles. When the electronic device detects the object to be measured, the second angle measurement mode can be switched to the first angle measurement mode for more accurate angle measurement, thereby accurately measuring the angle of the object to be measured relative to the electronic device. In addition, by setting two angle measurement modes, the angle measurement performance of the electronic device can be improved, which is conducive to the electronic device accurately measuring the angle of the object to be measured relative to the electronic device. That is, the object to be measured is first detected using the angle measurement mode with a large angle measurement coverage range, and then the angle measurement mode with high angle measurement accuracy is used for accurate measurement.

[0054] In addition, in some embodiments, the first antenna 10 , the second antenna 20 , the third antenna 30 , and the fourth antenna 40 are all formed by at least one of a flexible circuit board, a printed circuit board, a plastic metallized structure, a ceramic metallized structure, and a metal middle frame.

[0055] For example, the first antenna 10 is composed of a ceramic metallized structure; for another example, the first antenna 10 is composed of a plastic metallized structure; for another example, the second antenna 20 is composed of a flexible circuit board; for another example, the third antenna 30 is composed of a metal middle frame and a flexible circuit board.

[0056] In addition, in some embodiments, the first antenna 10, the second antenna 20, the third antenna 30, and the fourth antenna 40 each include at least one of a microstrip patch antenna, an inverted-F antenna, a loop antenna, a slot antenna, a monopole antenna, and a dipole antenna.

[0057] For example, the first antenna 10 includes a loop antenna; for another example, the first antenna 10 includes a slot antenna and a monopole antenna; for another example, the second antenna 20 includes an inverted-F antenna.
