Description

Technical Field

[0002] With the deployment of satellite systems (such as the Tiantong NTN satellite system which has three high-orbit satellites), in actual use, mobile terminals can establish a link with satellites through an omnidirectional antenna.

[0003] However, due to the limited communication distance of satellite communication itself, the communication connection between mobile terminals and satellites is unstable. In order to maintain a reliable link, users often need to change the posture and angle of holding the mobile phone to ensure the connection and sufficient signal strength, which is quite limiting.

Detailed Implementation

[0010] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0011] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0012] In the following description, the terms "first" and "second" are used merely to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first" and "second" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this disclosure described herein can be implemented in an order other than that illustrated or described herein.

[0013] Unless otherwise defined, all technical and scientific terms used in this disclosure have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used in this disclosure is for the purpose of describing embodiments of this disclosure only and is not intended to be limiting of this disclosure.

[0014] It should be understood that in the various embodiments of this disclosure, the sequence number of each implementation process does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this disclosure.

[0015] Figure 1 This is a flowchart illustrating a communication method provided in an embodiment of the present disclosure; as shown below. Figure 1 As shown, the method includes: Step 101: Obtain the position information between the electronic device and the target satellite; Step 102: Determine the target communication direction based on the position information between the electronic device and the target satellite; Step 103: Determine the antenna radiation direction of the electronic device based on the target communication direction.

[0016] Here, the method can be applied to electronic devices, which can be any device that can communicate with satellites via an antenna, such as mobile phones, outdoor satellite communicators, smart wearables that integrate satellite communication, etc.

[0017] The positional information between the electronic device and the target satellite may include: the pose of the electronic device and the position of the target satellite; it may also include the relative positional relationship between the two determined based on the pose of the electronic device and the position of the target satellite. The pose of the electronic device may include: latitude, longitude, altitude, and other positional information determined by navigation, base stations, etc., as well as the device's own attitude (e.g., the tilt angle of the handheld device, the device's movement speed, and direction). The position of the target satellite may include: the satellite's current latitude, longitude, altitude, etc.

[0018] This location information can be used to determine the target communication direction, which refers to the direction that the communication needs to be directed towards. For example, if the satellite is in a certain direction of the electronic device, say southeast with an elevation angle of 40 degrees, then the target communication direction can be determined as southeast with an elevation angle of 40 degrees.

[0019] The direction of antenna radiation can refer to the peak direction of the main lobe in the antenna pattern (radiation pattern), that is, the direction in which the power density radiated or received by the antenna is the largest and the signal energy is the most concentrated. Therefore, it can also be called the direction of the main lobe of the antenna pattern.

[0020] In this way, the target communication direction is determined based on the positional information between the electronic device and the target satellite, and the antenna radiation direction is determined based on the target communication direction. This concentrates signal energy in the target communication direction, thus avoiding communication instability and poor communication quality caused by misalignment. Furthermore, the entire process requires no user intervention (such as manually rotating to find the signal, maintaining a specific posture, or checking a compass app to align with the satellite orbit). The electronic device automatically adjusts and maintains the satellite connection, improving the reliability and application value of the electronic device.

[0021] In some embodiments, the method further includes: Based on the antenna radiation direction, a target radiator is determined among multiple radiators of the electronic device; the multiple radiators correspond to different antenna radiation directions. To make the target radiator conductive.

[0022] Here, electronic devices can have multiple radiators, and the conduction of each radiator can achieve different antenna radiation directions. That is, the communication quality is optimal when each radiator can radiate or receive signals in a certain direction.

[0023] In one example, suppose a satellite antenna is mounted on top of an electronic device. This antenna has multiple radiators, including a left radiator, a middle radiator, and a right radiator. By directly energizing different segments of the radiators, different antenna radiation directions (i.e., different main lobe directions of the antenna pattern) can be generated. For example, as... Figure 2 As shown, the electronic device is specifically a mobile phone. The top of the mobile phone has a satellite antenna, which can achieve different antenna radiation directions by connecting different radiators, such as the direction corresponding to angle interval 1 and the direction corresponding to angle interval 2 in the figure.

[0024] Once the target communication direction is determined, based on various possible antenna radiation directions, an antenna radiation direction that matches the target communication direction is selected. The radiator corresponding to the matched antenna radiation direction is then used as the target radiator and made to conduct, thereby forming an antenna radiation direction that matches the target communication direction.

[0025] In this way, the required antenna radiation direction is determined based on the target communication direction. A suitable target radiator is selected from multiple radiators that can point to different antenna radiation directions and directly activated, ensuring the antenna main lobe is precisely aligned with the signal source direction, effectively improving the receiving and transmitting gain and signal stability. Furthermore, the above process requires no user intervention; the electronic device can automatically adapt to different placement postures and positional relationships, and flexibly switch target radiators, improving the reliability, convenience, and smooth user experience of the electronic device.

[0026] In some embodiments, the method further includes: Based on the antenna radiation direction, a target feed point is determined among multiple feed points of the electronic device; the multiple feed points correspond to different antenna radiation directions. Turn on the radiator corresponding to the target feed point.

[0027] Here, electronic devices can be designed with multiple feed points, each feed point having its corresponding radiation direction. After a signal is connected to different feed points, the resulting antenna radiation direction will be different.

[0028] After determining the desired antenna radiation direction, the electronic device selects a feed point from multiple feed points that matches the desired antenna radiation direction as the target feed point, so as to realize the antenna radiation direction through the target feed point.

[0029] In one example, the electronic device has multiple feed points (assuming two) and multiple radiators (assuming three). The first feed point corresponds to the first radiator, the second feed point corresponds to the second radiator, and the third radiator is located between the first and second radiators. After determining the antenna radiation direction, the first feed point is matched and identified as the target feed point. The first feed point is then turned on, causing the first radiator corresponding to the first feed point to conduct, thus achieving the desired antenna radiation direction.

[0030] Specifically, when a signal is injected from the first feed point, a current is generated on the radiator it directly contacts (i.e., the first radiator), and the current on the first radiator can generate an electromagnetic field in the surrounding area. Furthermore, the second and third radiators can be driven based on signal coupling.

[0031] For radiators with multiple feed points, electronic devices can select or switch the conduction of the radiator using a switch. In one example, such as... Figure 3 The diagram shows an example of antenna feeding, where the electronic device can be a mobile phone with two feeding points.

[0032] To control the conduction of the radiators corresponding to the feed points, the mobile phone features an NTN (Non-Terrestrial Network) chip. This chip is responsible for satellite communication attitude calculation, azimuth determination, and target communication direction determination. This chip connects to the NTN RF front-end, which can be used for signal frequency conversion, amplification, filtering, transmit / receive switching, and conversion between digital and high-frequency RF signals. The NTN RF front-end is connected to a switch with only one output path, meaning that only feed point 1 or feed point 2 can be activated at a time. Feed point 1 and feed point 2 are located at the two radiators of the mobile phone antenna. By switching the switch, the radiators corresponding to different feed points are activated, resulting in two different antenna patterns.

[0033] Among these, the difference in antenna radiation patterns at least characterizes the direction of the main lobe of the antenna radiation pattern. For example... Figure 4 and Figure 5 As shown, simulation examples of antenna patterns with two different main lobe directions are provided, and the two directions are achieved through different feed points.

[0034] Based on the location information, the target communication direction within the corresponding angle range is determined. The electronic equipment adjusts the antenna radiation direction to the corresponding range by controlling the switch to switch different antenna feed points to adjust the main lobe direction of the antenna pattern, so as to maintain the maximum gain of the actual antenna within the satellite elevation angle range.

[0035] In this way, the electronic device automatically adapts to the signal orientation based on the positional relationship between the electronic device and the satellite, automatically selects the feed point to directly drive the corresponding radiator, and precisely adjusts the antenna radiation direction, greatly improving the signal strength and communication stability; and the entire process requires no manual operation from the user, making it seamless and ensuring that satellite communication is always in good condition.

[0036] In some embodiments, obtaining position information between the electronic device and the target satellite includes: Acquire attitude information of the electronic device; and / or Obtain the satellite position information of the target satellite; Based on the attitude information and / or satellite position information, the position information between the electronic device and the target satellite is determined, and the position information includes the angle information and distance information between the electronic device and the target satellite.

[0037] Here, electronic devices can have built-in devices such as gyroscopes, accelerometers, and geomagnetic sensors to collect real-time attitude information of the electronic device, such as whether the electronic device is held vertically, placed flat, tilted, flipped left or right, or has a pitch angle, so as to determine the orientation and tilt angle of the electronic device in space.

[0038] Electronic devices can search for and identify the target satellite that needs to be communicated with, obtain the target satellite's real-time satellite position information, such as on-orbit coordinates, azimuth, elevation angle, and azimuth angle, and determine the specific spatial location of the target satellite in space.

[0039] Based on attitude information and / or satellite position information, the angle and distance information (i.e., position information) between the electronic device and the target satellite can be determined.

[0040] In one example, after the electronic device determines its own attitude information, it can combine preset common satellite orientation data to calculate the relative angle between the electronic device's orientation and the target satellite, and estimate the spatial distance.

[0041] In another example, after the electronic device obtains the satellite's on-orbit coordinates, altitude, and other satellite position information, it can determine the spatial angle and spatial distance with the target satellite without referring to the placement attitude of the electronic device, using the fixed latitude and longitude coordinates of the electronic device or the coordinates of a preset location as a reference.

[0042] In another example, after determining the precise attitude information of the electronic device and the satellite position information of the target satellite, based on the determined information, the azimuth angle of the electronic device relative to the target satellite, combined with the real-time handheld tilt and deflection attitude of the electronic device, the difference angle is calculated to adjust the precise relative angle of the actual orientation of the satellite antenna of the electronic device relative to the target satellite (i.e., determine the angle information between the electronic device and the target satellite), and then the distance information is calculated based on the precise coordinates.

[0043] In another example, satellite position information may also include satellite speed; electronic devices can predict the satellite position after a period of time (e.g., 1 second, 2 seconds, 3 seconds, etc.), and combine this with their own position after a period of time based on the predicted satellite position and their own position; based on the predicted satellite position and their own position, they can determine the position information between the electronic devices and the target satellite after a period of time, and then predict the target communication direction after a period of time, and automatically adjust to the corresponding antenna radiation direction after a period of time.

[0044] In this way, the positional information of the electronic device and the target satellite is determined, providing accurate data for subsequent determination of the target communication direction and automatic switching of the antenna radiation direction. This method does not need to consider changes in the user's holding posture or rotation direction when holding the electronic device. It updates the attitude information of the electronic device in real time, quickly recalculates the alignment angle, and automatically adjusts the antenna radiation direction. There is no need to manually straighten the electronic device to align with the target satellite, which greatly improves the convenience of user operation and also improves communication speed and connection success rate.

[0045] In some embodiments, obtaining the satellite position information of the target satellite includes: Acquire signal strength information between electronic devices and at least one satellite and / or operational information of at least one satellite; Based on the signal strength information and / or operational information of the at least one satellite, the target satellite is determined among the at least one satellite.

[0046] Here, a satellite communication system can have multiple satellites, and electronic devices can identify the target satellite from among the multiple satellites.

[0047] In one example, the electronic device can obtain the signal strength between itself and each satellite. The signal strength can be measured by the electronic device itself, for example, by receiving information broadcast by the satellite or signal references sent by the ground station, to determine the link quality between each satellite and the electronic device. The better the link quality, the stronger the satellite signal (generally the closer the satellite is, the less obstruction there is, or the less signal attenuation). Thus, the satellite with the strongest signal strength is selected as the target satellite.

[0048] In another example, the electronic device can obtain operational information of each satellite, such as satellite ephemeris (which may include the satellite's position, trajectory, and operating range for a period of time), load status (remaining communication capacity), and operational status (whether there is a fault, whether emergency communication is prioritized). Based on this information, the electronic device can select target satellites, such as selecting satellites with matching locations; if the user is exercising outdoors, they can select satellites with matching locations for the current period and for a period of time; or select satellites with less load, etc.

[0049] In another example, the electronic device can simultaneously acquire the signal strength between itself and each satellite and the operational information of each satellite. It can then combine the two pieces of information to select a target satellite. The selection method can adopt preset rules, such as selecting the satellite with the highest elevation angle or the strongest communication signal, or selecting the satellite with a signal strength exceeding a preset threshold and the best matching location. For example, if the user is indoors, considering that low-Earth orbit satellites are easily blocked by buildings due to their low elevation angle, a high-Earth orbit satellite with a better signal can be selected. If the user is operating outdoors (i.e., the electronic device is moving at high speed), a low-Earth orbit satellite can be selected to ensure the data rate.

[0050] The above options are just examples and are not intended to limit the choices.

[0051] In this way, selecting a matching target satellite avoids problems such as poor signal leading to interrupted calls due to blindly selecting satellites, thus improving the quality of satellite communication; moreover, the above selection does not require user operation, and electronic devices can make the selection operation automatically.

[0052] The following combination Figure 2To illustrate, suppose an electronic device can radiate from two antennas. When the device is perpendicular to the ground, the angle ranges corresponding to the two antenna radiation directions can be symmetrical, and each antenna radiation direction covers the same area. Figure 2 The angle intervals 1 and 2 in the middle cover approximately 0° to 90° in the vertical direction, meaning that normal communication is possible from the horizontal direction to the top of the head. In the horizontal direction, each covers 0° to 180°. The combined coverage of the two symmetrically arranged angle intervals is close to omnidirectional.

[0053] Assuming the electronic device can achieve four antenna radiation directions, when the electronic device is perpendicular to the ground, the angle ranges corresponding to the radiation directions of two adjacent antennas can be symmetrical. The coverage range of each antenna radiation direction can be the same. For example, the vertical coverage is still about 0°~90°, that is, normal communication can be achieved from the horizontal direction to the top of the head, while the horizontal coverage is 0°~90°. After the four are symmetrically arranged, the combined coverage is close to omnidirectional.

[0054] The following combination Figure 2 This will be further explained by the radiation directions of the two antennas.

[0055] Assume the satellites that the current electronic device can communicate with include Satellite 1, Satellite 2, and Satellite 3. Satellite 1 has an elevation angle of 30° and an orbital altitude of 550 km; Satellite 2 has an elevation angle of 55° and an orbital altitude of 500 km; and Satellite 3 has an elevation angle of 20° and an orbital altitude of 800 km. Combining the satellite coordinates and the electronic device's coordinates, with the electronic device as the origin, determine the first direction in which Satellite 1 is located (e.g., ...). Figure 2 (As shown on the left), Satellite 2 and Satellite 3 are located in the second direction of the electronic equipment (as shown on the left). Figure 2 (As shown on the right).

[0056] Existing satellites can be deleted based on certain principles. For example, although satellites 2 and 3 are located in the same direction as the electronic device in the second direction, satellite 3 can be excluded if it is too far away from the electronic device (e.g., exceeding a certain threshold) and has a lower elevation angle. For the remaining satellites, further selection can be made based on the attitude of the electronic device.

[0057] For example, assuming the electronic device is placed vertically, the radiation directions of the two antennas of the electronic device can correspond to angle range 1 and angle range 2 respectively. At this time, the satellite elevation angle (i.e., the angle between the satellite and the horizon where the electronic device is located) or the communication signal strength can be further combined to make a selection. For example, if the highest elevation angle is selected, then satellite 2 is selected as the target satellite, or the satellite with the strongest communication signal strength is selected as the target satellite.

[0058] Assuming the electronic device is not placed vertically, the orientation of the satellite (e.g., left, right, or up) can be determined by combining the attitude of the electronic device. Combining the azimuth and elevation angles of the satellite, the direction the antenna of the electronic device is pointing towards the satellite can be determined. Generally, it is assumed that pointing the electronic device in the direction of the satellite allows the antenna beam to be aligned with the satellite. For example... Figure 2 If the antenna tilts to the left, then the antenna is pointing to the left (corresponding to interval 1), and the electronic device can select satellite 1 as the target satellite; if the antenna tilts to the right, then the antenna is pointing to the right (corresponding to interval 2), and satellite 2 can be selected as the target satellite; if the antenna is placed vertically upwards, the selection can be further combined with the satellite elevation angle or the signal strength of the communication.

[0059] It should be noted that if the electronic device cannot determine its own attitude, the placement attitude of the electronic device can be disregarded. Instead, the fixed latitude and longitude coordinates of the electronic device or the coordinates of a preset location can be used as a reference to determine the spatial angle and spatial distance of the satellite. Based on this, candidate satellites can be selected (e.g., the closest satellite with the highest elevation angle can be selected). Then, the signal strength of communication with the candidate satellite can be detected, and the target satellite can be selected.

[0060] If the electronic device can only determine its own attitude, it can combine the preset common satellite general orientation data to calculate the relative angle between the electronic device's orientation and the target satellite, estimate the spatial distance, and then select the target satellite after detecting the signal strength of communication with the candidate satellite.

[0061] After identifying the target satellite, the position information between the electronic device and the target satellite is determined. The position information includes the angle information and distance information between the electronic device and the target satellite. For example, if the position of the target satellite belongs to a certain angle range of the electronic device, the antenna radiation direction can be further determined. If it belongs to angle range 1, the antenna radiation direction corresponding to that angle range is selected.

[0062] In some embodiments, the method further includes: The grip information of the electronic device is obtained, and the grip information is used to indicate the shielding status of multiple radiators of the electronic device; Determining the target communication direction based on the position information between the electronic device and the target satellite includes: The target communication direction is determined based on the grip information and the position information between the electronic device and the target satellite.

[0063] Here, considering that if the electronic device is a handheld device such as a mobile phone, there may be signal obstruction when the user holds it, the holding information of the electronic device can also be determined. The holding information can be autonomously collected and determined by the electronic device through its built-in sensors, such as determining the holding posture of the electronic device (portrait or landscape), whether it is held with the left or right hand, where it is held on the electronic device, whether gloves are worn, etc.

[0064] In the initial stage, the mapping relationship between different holding postures and the radiation direction of the blocked antenna (and the corresponding feed point and radiator) can be tested and determined in advance. For example, when holding the screen vertically with the right hand, the hand will block the first radiator of the electronic device, and when holding the screen horizontally with both hands, the hand will block the second radiator.

[0065] Based on the above mapping relationship, after determining the holding information, the target communication direction is determined by combining the position information between the electronic device and the target satellite. For example, the direction corresponding to the radiator that is being held and shielded is excluded, and the target communication direction is selected from the remaining available communication directions.

[0066] In this way, communication quality is not affected by the grip posture, and users do not need to adjust their grip or find the best angle for the signal. The satellite link can be maintained even when holding electronic devices normally.

[0067] In some embodiments, the method further includes: Detect the communication quality of the electronic device; In response to a detected communication quality being less than a first threshold, the target communication direction is determined based on the position information between the electronic device and the target satellite.

[0068] Here, communication quality refers to the quality of the satellite link between the current electronic device and the target satellite. The communication quality can be determined by collecting parameters such as the received signal strength, signal-to-noise ratio, packet loss rate, transmission rate, and link jitter of the link. This allows for timely detection of link quality changes and avoids problems such as lag, disconnection, and message sending failure that are perceptible to the user.

[0069] The first threshold can be a pre-set indicator for judging communication quality, and there is no limit to its specific value.

[0070] When an electronic device determines that the communication quality is below the first threshold, it is considered that the current communication quality of the electronic device is poor and the target communication direction needs to be re-determined. Then, based on the position information between the electronic device and the target satellite, the target communication direction is re-determined, and the antenna radiation direction of the electronic device is adjusted to improve the communication quality.

[0071] In this way, the quality of the satellite link is monitored in real time. Once the quality drops below the first threshold, the target communication direction is determined, so that the communication remains continuous and stable in various scenarios such as movement, obstruction or attitude change, thereby improving link availability and user experience.

[0072] Figure 6 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this disclosure; as shown below. Figure 6 As shown, the electronic device 60 includes: Antenna 605 includes multiple feed points; The processor 601 and the memory 602 for storing computer programs that can run on the processor; when the processor 601 runs the computer program, it executes the communication method provided in the embodiments of this disclosure.

[0073] In some embodiments, at least a portion of the antenna is formed by the frame of the electronic device, the antenna includes a plurality of radiators, and the feed points include at least a first feed point and a second feed point disposed at both ends of the frame; The first feed point and the second feed point are respectively located at both ends of the same radiator; Alternatively, the first feed point and the second feed point are respectively located on the first radiator and the second radiator at both ends of the frame.

[0074] Here, the antenna is a built-in antenna of an electronic device, which can directly utilize the frame of the electronic device (such as a mobile phone) as the antenna body. The antenna has multiple independent radiators, and at least two feed points are arranged at the frame position, designated as the first feed point and the second feed point, respectively, located at the left and right ends of the frame.

[0075] In one example, the top border can have a single, continuous radiator without being segmented. The first feed point is located at the left end of the radiator, and the second feed point is located at the right end of the same segment of the radiator, meaning that the two feed points share the same radiator.

[0076] After determining the target communication direction and the required antenna radiation direction for that target communication direction, the antenna radiation direction can be changed by switching on the first feed point or the second feed point to change the current flow direction and current distribution position on the radiator. That is, the antenna radiation direction can be changed by changing the feed access position.

[0077] In another example, the top bezel may have multiple independent radiators (e.g., radiators separated by insulating gaps), specifically including a first radiator and a second radiator, wherein the two feed points are not connected to each other and each corresponds to a separate radiator (e.g., the first feed point is set on the first radiator and the second feed point is set on the second radiator).

[0078] When the first feed point is connected, the first radiator is directly driven to work; when the second feed point is connected, the second radiator is directly driven to work. In this way, by switching between connecting the first and second feed points, the direction of current flow and the current distribution position on the radiator are changed, thereby changing the antenna radiation direction. That is, the antenna radiation direction is changed by changing the feed connection position.

[0079] In another example, the top bezel may have multiple independent radiators (e.g., radiators separated by insulating gaps), specifically including a first radiator, a second radiator, and a third radiator, with the third radiator located between the first and second radiators; wherein, the two feed points are not connected to each other and each corresponds to a separate radiator, such as the first feed point being located on the first radiator and the second feed point being located on the second radiator.

[0080] When the first feed point is turned on, the first radiator is directly driven to operate, while the third and second radiators are driven based on signal coupling (generating a weak induced current through signal coupling). Similarly, when the second feed point is turned on, the second radiator is directly driven to operate, while the third and first radiators are driven based on signal coupling (generating a weak induced current through signal coupling).

[0081] like Figure 7 As shown, a schematic diagram of the positions of the first feed point and the second feed point is provided. Taking an antenna including a first radiator, a second radiator, and a third radiator, with two feed points as an example, feed point 1 and feed point 2 are respectively located on the first radiator and the third radiator. Furthermore, in some examples, the positions of the two feed points can also have a certain relationship, such as being symmetrical along the Y-axis, where the Y-axis is the coordinate system of the top view of the electronic device. In this way, by connecting feed point 1 or feed point 2, the directions of the main lobes of the two antenna radiation patterns are achieved in a completely symmetrical manner.

[0082] In another example, the feed points may include: a first feed point, a second feed point, a third feed point, and a fourth feed point. The first and third feed points can be located on the same radiator, and the second and fourth feed points can also be located on the same radiator. Compared to the case of two feed points, increasing the number of feed points increases the number of satellite elevation angle intervals. Simultaneously, by considering the actual mobile phone antenna environment, the main lobe angle of the antenna pattern can be narrowed, enabling more antenna radiation directions and improving the antenna gain in the corresponding antenna radiation directions within the elevation angle interval, thereby improving the overall system performance.

[0083] like Figure 8The diagram illustrates the locations of four feed points. Specifically, using the coordinate system of a top-view view of the electronic device, the first and third feed points can be located on the same radiator (e.g., the first radiator), and the second and fourth feed points can also be located on the same radiator (e.g., the third radiator). In some examples, the positions of the feed points can also have certain relationships. For instance, the positions of the first and second feed points can be symmetrical along the Y-axis, and the positions of the third and fourth feed points can also be symmetrical along the X-axis. Here, the X and Y axes represent the coordinate system of a top-view view of the electronic device. This allows for four different antenna radiation directions, improving the antenna gain in the corresponding antenna radiation directions within the elevation range.

[0084] It should be noted that an antenna can have one radiator, two radiators, three radiators, etc., and this is not limited here; it is only used to illustrate the relative positions of the four feed points.
