[0001] This application belongs to the field of communication technology, specifically relating to an antenna control system, an antenna control method, and an electronic device. Background Technology

[0002] With the development of communication technology, the performance of electronic devices such as mobile phones and tablets has been continuously improved, and the frequency bands on the antennas of these devices have also increased, with antenna performance continuously being enhanced. Among them, ultra-wideband (UWB) antennas, due to their advantages such as wide bandwidth, strong anti-interference capability, and multipath resistance, can be used for high-precision ranging and angle measurement. Therefore, more and more electronic devices are using UWB antennas.

[0003] Currently, ultra-wideband antennas typically employ PDOA (Phase Difference of Arrival) angle measurement technology. PDOA technology places certain requirements on the spacing 'd' between antenna elements in an ultra-wideband antenna. To achieve -90° to 90° AOA (Angle-of-Arrival) angle measurement, the antenna element spacing needs to be... However, a smaller antenna element spacing d leads to a deterioration in angle measurement accuracy and a decrease in overall positioning performance. When the antenna element spacing d... While this improves the angle measurement accuracy, it also reduces the AOA angle measurement range. In other words, existing ultra-wideband antennas struggle to balance angle measurement range and accuracy, thus diminishing the user experience. Summary of the Invention

[0004] This application aims to provide an antenna control system, antenna control method, and electronic device to solve the problem that existing ultra-wideband antennas have difficulty balancing angle measurement range and angle measurement accuracy when measuring angles.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, this application discloses an antenna control system, which includes: a transceiver controller, a first switch, a first antenna array, and a second antenna array;

[0007] The first antenna array includes multiple spaced first antennas, and the distance between two adjacent first antennas is a first distance. The second antenna array includes multiple spaced second antennas, and the distance between two adjacent second antennas is a second distance. The first distance is smaller than the second distance.

[0008] One end of the first switch is electrically connected to the transceiver controller, and the other end of the first switch is electrically connected to the first antenna array and the second antenna array respectively.

[0009] The transceiver controller is used to control the first switch to turn on the first antenna array so as to obtain the first angle measurement through the first antenna array; when the first angle measurement meets the angle measurement range of the second antenna array, it controls the first switch to turn on the second antenna array so as to obtain the second angle measurement through the second antenna array; and based on the second angle measurement and the first angle measurement, it determines the target angle measurement.

[0010] Secondly, this application also discloses an antenna control method for the antenna control system described in any of the above claims, the antenna control method comprising:

[0011] Control the first antenna array to obtain the first angle measurement; wherein, the first antenna array includes multiple first antennas arranged at intervals;

[0012] If the first angle measurement meets the angle measurement range of the second antenna array, the second antenna array is controlled to acquire the second angle measurement; wherein, the second antenna array includes multiple second antennas arranged at intervals;

[0013] The target angle is determined based on the second and first angle measurements.

[0014] Thirdly, embodiments of this application also disclose an electronic device, which includes: the antenna control system of any one of the above.

[0015] In this embodiment, the antenna control system may include a first antenna array and a second antenna array. The first spacing between the first antennas in the first antenna array is smaller than the second spacing between the second antennas in the second antenna array. Therefore, the first antenna array has a larger angular measurement range, and the second antenna array has higher angular measurement accuracy. In specific applications, the transceiver controller can control the first antenna array to acquire a first angular measurement to achieve a larger angular measurement range. If the first angular measurement satisfies the angular measurement range of the second antenna array, the second antenna array can be controlled to acquire a second angular measurement to achieve higher angular measurement accuracy. Finally, based on the second and first angular measurements, a target angular measurement can be determined to achieve both a larger angular measurement range and higher angular measurement accuracy, improving the user experience of the antenna control system.

[0027] Reference Figure 1 The diagram illustrates a structural schematic of an antenna control system according to an embodiment of this application, as shown below. Figure 1 As shown, the antenna control system may specifically include: a transceiver controller 10, a first switch 11, a first antenna array 12, and a second antenna array 13; the first antenna array 12 may include multiple spaced first antennas 121, with the spacing between two adjacent first antennas 121 being a first spacing; the second antenna array 13 may include multiple spaced second antennas 131, with the spacing between two adjacent second antennas 131 being a second spacing, and the first spacing being smaller than the second spacing; one end of the first switch 11 is electrically connected to the transceiver controller 10, and the other end of the first switch 11 is electrically connected to the first antenna array 12 and the second antenna array 13 respectively; wherein, the transceiver controller 10 may be used to control the first switch 11 to conduct the first antenna array 12 to obtain a first angle measurement through the first antenna array 12; when the first angle measurement meets the angle measurement range of the second antenna array 13, control the first switch 11 to conduct the second antenna array 13 to obtain a second angle measurement through the second antenna array 13; and determine the target angle measurement based on the second angle measurement and the first angle measurement.

[0028] In this embodiment, the antenna control system may include a first antenna array 12 and a second antenna array 13. The first spacing between the first antennas 121 in the first antenna array 12 is smaller than the second spacing between the second antennas 131 in the second antenna array 13. Therefore, the first antenna array 12 has a larger angle measurement range, and the second antenna array 13 has higher angle measurement accuracy. In specific applications, the transceiver controller 10 can control the first antenna array 12 to acquire a first angle measurement to achieve a larger angle measurement range. When the first angle measurement meets the angle measurement range of the second antenna array 13, the second antenna array 13 can be controlled to acquire a second angle measurement to achieve higher angle measurement accuracy. Finally, based on the second and first angle measurements, a target angle measurement can be determined to achieve a larger angle measurement range and higher angle measurement accuracy, improving the user experience of the antenna control system.

[0029] Specifically, both the first antenna array 12 and the second antenna array 13 can be ultra-wideband antenna arrays, and both can perform AOA angle measurement. The transceiver controller 10, as the main controller of the antenna control system, can control the transmission, reception, and processing of antenna signals to output the angle measurement positioning result. A first switch 11 is located between the transceiver controller 10 and the first antenna array 12 and the second antenna array 13. The first switch 11 can control the connection and disconnection between the transceiver controller 10 and the first antenna array 12 and the second antenna array 13. Specifically, when the transceiver controller 10 controls the first switch 11 to conduct the first antenna array 12, AOA angle measurement can be performed through the first antenna array 12 to obtain the first angle. When the transceiver controller 10 controls the first switch 11 to conduct the second antenna array 13, AOA angle measurement can be performed through the second antenna array 13 to obtain the second angle.

[0030] Reference Figure 2 This illustrates the layout of the first and second antenna arrays in an electronic device according to embodiments of this application, as shown below. Figure 2 As shown, the first spacing between the first antennas 121 in the first antenna array 12 is smaller than the second spacing between the second antennas 131 in the second antenna array 13. Therefore, during the AOA angle measurement process, the first antenna 121 can obtain a larger angle measurement range, but the angle measurement accuracy may decrease slightly. The angle measurement range of the second antenna 131 is smaller than that of the first antenna 121, but it can obtain a larger angle measurement accuracy.

[0031] Optionally, the first spacing is less than or equal to λ / 2. In this way, during AOA angle measurement, the phase difference between the two first antennas 121 within the range of -180° to 180° can achieve AOA angle measurement from -90° to 90°, enabling omnidirectional angle measurement. The second spacing can be greater than or equal to λ / 2. In this way, the second linear array 13 cannot achieve AOA angle measurement from -90° to 90° during AOA angle measurement, but within its measurement range, the second linear array 13 has higher angle measurement accuracy.

[0032] For example, the angle measurement range of the first antenna array 12 can be -90° to 90°, and by setting the size of the second spacing, the angle measurement range of the second antenna array 13 can be -60° to 60°.

[0033] In practical applications, during angle measurement, the transceiver controller 10 can first control the first switch 11 to activate the first antenna array 12 to obtain the first angle measurement. Since the angle measurement range of the first antenna array 12 is -90° to 90°, it can achieve comprehensive angle measurement. If the first angle measurement does not meet the angle measurement range of the second antenna array 13, the first angle measurement can be used as the final target angle measurement; if the first angle measurement meets the angle measurement range of the second antenna array 13, the transceiver controller 10 can control the first switch 11 to activate the second antenna array 13 to obtain the second angle measurement. Because the angle measurement accuracy of the second antenna array 13 is higher, the accuracy of the second angle measurement is higher than that of the first angle measurement.

[0034] For example, if the angle measurement range of the second antenna array 13 can be -60° to 60°, and the first angle measurement obtained by the first antenna array 12 is 50°, the transceiver controller 10 can further control the second antenna array 13 to measure the angle in order to obtain a second angle measurement with higher accuracy.

[0035] In this embodiment of the application, after obtaining the second angle, the final target angle can be determined based on the second angle and the first angle.

[0036] In one optional embodiment of this application, the second angle measurement can be directly used as the final target angle measurement. Since the accuracy of the second angle measurement is higher than that of the first angle measurement, using the second angle measurement as the final target angle measurement is beneficial to obtaining higher angle measurement accuracy compared to the first angle measurement.

[0037] In another optional embodiment of this application, a target angle can be determined based on a first measured angle and its corresponding first preset weight, and a second measured angle and its corresponding second preset weight, to further improve the accuracy of the target angle measurement. Specifically, the target angle can be a weighted sum of the first and second measured angles; that is, the product of the first measured angle and the first preset weight is added to the product of the second measured angle and the second preset weight to obtain the target angle. Since the final target angle comprehensively considers the influencing factors of the first and second measured angles, the accuracy of the target angle measurement can be further improved.

[0038] In practical applications, the first and second preset weights can be set according to the actual situation. Since the accuracy of the second angle measurement is greater than that of the first angle measurement, the second preset weight can be greater than the first preset weight. For example, the first preset weight can be 0.2, and the second preset weight can be 0.8.

[0039] In another optional embodiment of this application, if the second measured angle is not within the measuring range of the second antenna array 13, the first measured angle is used as the target measured angle. In practical applications, if the second measured angle is not within the measuring range of the second antenna array 13, it can be assumed that the sensed target has exceeded or moved out of the measuring range of the second antenna array 13, and the second measured angle obtained by the second array antenna has a large error and needs to be discarded. In this case, the first measured angle can be used again as the final target measured angle to ensure that the target measured angle is truly effective.

[0040] In practical applications, when the second angle measurement falls within the angle measurement range of the second linear array 13, the final target angle measurement can be determined by referring to the aforementioned method.

[0041] Reference Figure 3 This illustrates a schematic diagram of another antenna control system according to an embodiment of this application, such as... Figure 3 As shown, the first switch 14 may include a first terminal and a second terminal. The antenna control system may further include: a second switch 14, a first bandpass filter 15, and a second bandpass filter 16; wherein: one terminal of the second switch 14 is electrically connected to the transceiver controller 10; one terminal of the first bandpass filter 15 and one terminal of the second bandpass filter 16 are electrically connected to the other terminal of the second switch 14, the other terminal of the first bandpass filter 15 is electrically connected to the first terminal of the first switch 14, and the other terminal of the second bandpass filter 16 is electrically connected to the second terminal of the first switch 11. In practical applications, the second switch 14 can be used to control the conduction or disconnection of the antenna signal transmission and reception path.

[0042] For example, when the second switch 14 and the first bandpass filter 15 are both on, the antenna's receiving path can be activated to receive the antenna signal; when the second switch 14 and the second bandpass filter 16 are both on, the antenna's transmitting path can be activated to receive the antenna signal. During angle measurement, the second switch 14 needs to frequently switch between the receiving and transmitting paths to achieve the angle measurement function of the ultra-wideband antenna. The first bandpass filter 15 and the second bandpass filter 16 can be used to allow antenna signals of useful frequencies to pass smoothly while blocking antenna signals of unused frequencies, thereby improving the quality of the antenna signal.

[0043] Optionally, the second switch 14 is a single-pole double-throw switch. Since single-pole double-throw switches have the advantages of simple structure and simple control logic, using a single-pole double-throw switch for the second switch 14 not only reduces the structural cost of the antenna control system but also simplifies the control logic and improves the operational efficiency of the antenna control system.

[0044] like Figure 3As shown, the first switch 11 may include a third terminal, and the antenna control may further include: a third switch 17, a third bandpass filter 18, a fourth bandpass filter 19, and a transmitting antenna 20; wherein: one end of the third switch 17 is electrically connected to the transceiver controller 10; one end of the third bandpass filter 18 and one end of the fourth bandpass filter 19 are electrically connected to the other end of the third switch 17, the other end of the third bandpass filter 18 is electrically connected to the third terminal of the first switch 11, and the other end of the fourth bandpass filter 19 is electrically connected to the transmitting antenna 20. In practical applications, the third switch 17 can work in conjunction with the second switch 14 to control the conduction or disconnection of the antenna signal transmission and reception path.

[0045] In practical applications, when the third switch 17 and the third bandpass filter 18 are both active, the receiving and / or transmitting paths of the antenna can be activated to enable the reception and / or transmission of antenna signals. When the third switch 17 and the fourth bandpass filter 19 are both active, the transmitting antenna 20 can be activated to enable the transmission of antenna signals. During angle measurement, the third switch 17 needs to work in conjunction with the second switch 14 to frequently switch between the receiving and transmitting paths to achieve the angle measurement function of the ultra-wideband antenna. The third bandpass filter 18 and the fourth bandpass filter 19 can be used to allow antenna signals of useful frequencies to pass smoothly while blocking antenna signals of unused frequencies, thereby improving the quality of the antenna signal.

[0046] In summary, the antenna control system of this application embodiment may include at least the following advantages:

[0047] In this embodiment, the antenna control system may include a first antenna array and a second antenna array. The first spacing between the first antennas in the first antenna array is smaller than the second spacing between the second antennas in the second antenna array. Therefore, the first antenna array has a larger angular measurement range, and the second antenna array has higher angular measurement accuracy. In specific applications, the transceiver controller can control the first antenna array to acquire a first angular measurement to achieve a larger angular measurement range. If the first angular measurement satisfies the angular measurement range of the second antenna array, the second antenna array can be controlled to acquire a second angular measurement to achieve higher angular measurement accuracy. Finally, based on the second and first angular measurements, a target angular measurement can be determined to achieve both a larger angular measurement range and higher angular measurement accuracy, improving the user experience of the antenna control system.

[0048] Reference Figure 4 The diagram illustrates a flowchart of the steps of an antenna control method according to an embodiment of this application. Figure 4 The antenna control method shown can be used in the antenna control systems of the above embodiments. The antenna control method includes:

[0049] Step 401: Control the first antenna array to obtain the first angle measurement; wherein, the first antenna array includes multiple first antennas arranged at intervals.

[0050] In this embodiment, the antenna control system may include a first antenna array and a second antenna array. The first antenna array may include multiple spaced-apart first antennas, with a first spacing between adjacent first antennas. The second antenna array may include multiple spaced-apart second antennas, with a second spacing between adjacent second antennas. The first spacing is smaller than the second spacing.

[0051] Specifically, both the first and second antenna arrays can be ultra-wideband antenna arrays, and both can achieve AOA (Optical Angle Assignment) measurement. The first spacing between the first antennas in the first antenna array is smaller than the second spacing between the second antennas in the second antenna array. Therefore, during AOA measurement, the first antenna can obtain a larger measurement range, but the measurement accuracy may decrease slightly. The second antenna has a smaller measurement range than the first antenna, but it can obtain greater measurement accuracy.

[0052] In this embodiment of the application, during the angle measurement process, the first switch can be controlled to turn on the first antenna array to obtain the first angle measurement. Since the angle measurement range of the first antenna array can be from -90° to 90°, all-around angle measurement can be achieved.

[0053] Step 402: If the first angle measurement meets the angle measurement range of the second linear array, control the second linear array to acquire the second angle measurement; wherein, the second linear array includes multiple second antennas arranged at intervals.

[0054] In this embodiment, if the first angle measurement meets the angle measurement range of the second antenna array, the transceiver controller can control the first switch to turn on the second antenna array to obtain the second angle measurement. Since the angle measurement accuracy of the second antenna array is higher, the accuracy of the second angle measurement is higher than that of the first angle measurement.

[0055] For example, if the angle measurement range of the second antenna array can be -60° to 60°, and the first angle measurement obtained by the first antenna array is 50°, the transceiver controller can further control the second antenna array to measure the angle, so as to obtain a second angle measurement with higher accuracy.

[0056] In practical applications, if the first angle measurement does not meet the angle measurement range of the second linear array, the first angle measurement can be used as the final target angle measurement.

[0057] Step 403: Determine the target angle based on the second angle measurement and the first angle measurement.

[0058] In this embodiment of the application, after obtaining the second angle, the final target angle can be determined based on the second angle and the first angle.

[0059] In one optional embodiment of this application, the step of determining the target angle based on the second angle and the first angle may include: directly using the second angle as the target angle. Since the accuracy of the second angle is higher than that of the first angle, using the second angle as the final target angle is beneficial to obtaining higher angle measurement accuracy compared to the first angle.

[0060] In another optional embodiment of this application, the step of determining the target angle based on the second angle and the first angle may include: determining the target angle according to the first angle and its corresponding first preset weight, and the second angle and its corresponding second preset weight, to further improve the accuracy of the target angle. Specifically, the target angle can be a weighted sum of the first angle and the second angle, that is, the product of the first angle and the first preset weight and the product of the second angle and the second preset weight are added together to obtain the target angle. Since the final target angle comprehensively considers the influencing factors of the first angle and the second angle, the accuracy of the target angle can be further improved.

[0061] In practical applications, the first and second preset weights can be set according to the actual situation. Since the accuracy of the second angle measurement is greater than that of the first angle measurement, the second preset weight can be greater than the first preset weight. For example, the first preset weight can be 0.2, and the second preset weight can be 0.8.

[0062] In another optional embodiment of this application, the step of determining the target angle based on the second angle measurement and the first angle measurement may include: if the second angle measurement does not fall within the angle measurement range of the second antenna array, using the first angle measurement as the target angle measurement. In practical applications, if the second angle measurement does not fall within the angle measurement range of the second antenna array, it can be assumed that the sensed target has exceeded or moved out of the angle measurement range of the second antenna array, and the second angle measurement obtained by the second array antenna has a large error and needs to be discarded. In this case, the first angle measurement can be used again as the final target angle measurement to ensure that the target angle measurement is truly effective.

[0063] In practical applications, when the second angle measurement falls within the angle measurement range of the second antenna array, the final target angle measurement can be determined by referring to the aforementioned method.

[0064] In summary, the antenna control method of this application embodiment may specifically include the following advantages:

[0065] In this embodiment, the antenna control system may include a first antenna array and a second antenna array. The first spacing between the first antennas in the first antenna array is smaller than the second spacing between the second antennas in the second antenna array. Therefore, the first antenna array has a larger angular measurement range, and the second antenna array has higher angular measurement accuracy. In specific applications, the transceiver controller can control the first antenna array to acquire a first angular measurement to achieve a larger angular measurement range. If the first angular measurement satisfies the angular measurement range of the second antenna array, the second antenna array can be controlled to acquire a second angular measurement to achieve higher angular measurement accuracy. Finally, based on the second and first angular measurements, a target angular measurement can be determined to achieve both a larger angular measurement range and higher angular measurement accuracy, improving the user experience of the antenna control system.
