[0139] The glass cover 13 can be set close to the display screen 15, and its main function is to protect the display screen 15 from dust. The display screen 15 of the electronic device 10 can be a large-size display screen with a screen-to-body ratio of over 90%.

[0140] The printed circuit board (PCB) 17 can be made of FR-4 dielectric material, Rogers dielectric material, or a hybrid dielectric material of Rogers and FR-4, etc. Here, FR-4 is a designation for a flame-retardant material grade, and Rogers dielectric material is a type of high-frequency board. A metal layer can be provided on the side of the PCB 17 closest to the housing 19. This metal layer can be formed by etching metal onto the surface of the PCB 17. This metal layer can be used to ground the electronic components carried on the PCB 17 to prevent electric shock to the user or damage to the equipment.

[0141] The housing 19 primarily serves to support the entire device. The housing 19 may include a frame 11, which can be formed of a conductive material such as metal, or a non-metallic material (e.g., a plastic frame). A conductive frame can form a frame antenna through slots, while a non-metallic frame can form a frame antenna by attaching an antenna radiator internally. The frame 11 can extend around the periphery of the electronic device 10 and the display screen 15, specifically surrounding the four sides of the display screen 15 to help secure it. In one implementation, the frame 11 made of a metallic material can be directly used as the metallic frame of the electronic device 10, forming a metallic frame appearance suitable for a metallic ID. In another implementation, the outer surface of the frame 11 can also be provided with a non-metallic frame, such as a plastic frame, forming a non-metallic frame appearance suitable for a non-metallic ID.

[0142] As shown in Figure 2, the frame 11 can be divided into four parts, which can be named according to their respective positions in the electronic device: top frame 11-5, bottom frame 11-7, second side frame 11-3, and first side frame 11-1. The top frame 11-5 can be located at the top of the electronic device 10, and the bottom frame 11-7 can be located at the bottom of the electronic device 10. The second side frame 11-3 and the first side frame 11-1 can be located on opposite sides of the electronic device 10. Near the top of the electronic device 10, a front-facing camera (not shown), an earpiece (not shown), and a proximity sensor (not shown) can be located. At the bottom of the electronic device 10, a USB charging port (not shown) and a microphone (not shown) can be located. On the sides of the electronic device 10, volume control buttons (not shown) and a power button (not shown) can be located where the second side frame 11-3 and / or the first side frame 11-1 are located.

[0143] The back cover 12 can be made of a non-conductive material, such as a glass back cover, a plastic back cover, or other non-metallic back cover. The back cover 12 can also be made of a conductive material such as metal, and a rear camera (not shown) can be installed on the back cover 12.

[0144] Figure 1 only schematically shows some of the components included in the electronic device 10, and the actual shape, size and construction of these components are not limited by Figure 1.

[0145] After introducing the internal environment of the electronic device 10 of this application, in order to elaborate on the antenna layout of the electronic device 10 with different folding functions, the display form of the display screen of the electronic device 10 provided in this application will be introduced next.

[0146] The display screen of electronic device 10 can include a flat screen and a foldable screen. Foldable screens can be further divided into bi-fold screens and multi-fold screens. Bi-fold screens can be divided into inward-folding screens, outward-folding screens, etc. Multi-fold screens can be tri-fold screens, etc.

[0147] Figures 3A-3C show schematic diagrams of the display form of the inward-folding screen.

[0148] The display forms of inward-folding screens can be divided into folded state, intermediate state, and unfolded state.

[0149] Figure 3A shows a schematic diagram of the display form when the inward-folding screen is in the unfolded state.

[0150] Figure 3A(a) exemplarily shows a front view of the inward-folding screen in its unfolded state. When the inward-folding screen is in its unfolded state, the displayable screens of the folding screen include screen A, screen B, and screen C. Screen A and screen B can be a single, complete display screen or two separate display screens. The display area containing screens A and B can also be referred to as the inner screen. For example, when the inward-folding screen is in its unfolded state, the angle α between screens A and B is greater than or equal to a first value and less than or equal to a second value. For example, the first value can be 160 degrees, and the second value can be 180 degrees. For instance, when the inward-folding screen is in its unfolded state, the angle α between screens A and B can be 180 degrees.

[0151] Figure 3A(b) exemplarily shows a rear view of the inward-folding screen in its folded state. When the inward-folding screen is in its folded state, the display also includes screen C. Screen C is a display completely independent of screens A and B.

[0152] Figure 3B shows a schematic diagram of the display form when the inward-folding screen is in the intermediate state.

[0153] The intermediate state refers to the folding shape where the inward-folding screen can be bent at a certain angle towards the facing surfaces of screens A and B. When the inward-folding screen is in this intermediate state, the displayable screens include screens A, B, and C. In this intermediate state, the angle α between screens A and B is greater than or equal to a third value and less than or equal to a first value. For example, the first value could be 160 degrees, and the third value could be 90 degrees. Alternatively, when the inward-folding screen is in its folded state, the angle α between screens A and B could be 120 degrees.

[0154] Optionally, Figure 3B only shows one display form when the inward-folding screen is in the intermediate state. The display form when the inward-folding screen is in the intermediate state is also different when the included angle α between screen A and screen B is different.

[0155] Figure 3C shows a schematic diagram of the display form when the inward-folding screen is in the folded state.

[0156] The inward-folding screen can continue to bend in the direction where screens A and B are facing each other, until the inward-folding screen is in a folded state.

[0157] As shown in Figure 3C, when the inward-folding screen is in the folded state, the only displayable screen includes screen C; screens A and B are hidden and invisible. The angle α between screens A and B is greater than or equal to 0 degrees and less than a third value. For example, the third value can be 90 degrees. For instance, when the inward-folding screen is in the folded state, the angle α between screens A and B can be 0 degrees.

[0158] Figures 3D-3F show schematic diagrams of the display form of the outward-folding screen.

[0159] Similar to inward-folding screens, outward-folding screens can also be divided into three display forms: unfolded, intermediate, and folded.

[0160] Figure 3D shows a schematic diagram of the display form when the outward-folding screen is in the unfolded state.

[0161] Figure 3D(a) exemplarily shows a front view of the outward-folding screen in its unfolded state. When the outward-folding screen is in its unfolded state, the displayable screens of the folding screen include screen A and screen B. Screen A and screen B can be a single, continuous display or two separate displays. Exemplarily, when the inward-folding screen is in its unfolded state, the angle α between screen A and screen B is greater than or equal to a first value and less than or equal to a second value. Exemplarily, the first value can be 160 degrees, and the second value can be 180 degrees. Exemplarily, when the outward-folding screen is in its unfolded state, the angle α between screen A and screen B can be 180 degrees.

[0162] Figure 3D(b) exemplarily shows a rear view of the outward-folding screen in its unfolded state. When the outward-folding screen is in its unfolded state, compared to the inward-folding screen, the display of the outward-folding screen does not include the C-screen.

[0163] Figure 3E shows a schematic diagram of the display form when the outward-folding screen is in the intermediate state.

[0164] The intermediate state refers to the folding shape where the outward-folding screen can bend in a direction opposite to screens A and B, forming a folded shape with a certain angle. In other words, the folding directions of the outward-folding screen and the inward-folding screen are opposite. When the outward-folding screen is in the intermediate state, the displayable screens include screens A and B, and the angle α between screens A and B is greater than or equal to a third value and less than or equal to a first value. For example, the third value could be 90 degrees, and the first value could be 160 degrees. For instance, when the outward-folding screen is in the intermediate state, the angle α between screens A and B could be 120 degrees.

[0165] Optionally, Figure 3E only shows one display form when the outward-folding screen is in the intermediate state. The angle α between screen A and screen B is different, and the display form when the inward-folding screen is in the intermediate state is also different.

[0166] Figure 3F shows a schematic diagram of the display form when the outward-folding screen is in the folded state.

[0167] As shown in Figure 3F, when the outward-folding screen is in the folded state, the displayable screens can be screen A and screen B. The angle α between screen A and screen B is greater than or equal to 0 degrees and less than or equal to a third value, for example, the third value can be 90 degrees. For example, when the outward-folding screen is in the folded state, the angle α between screen A and screen B can be 0 degrees.

[0168] Optionally, the inward-folding and outward-folding screens shown in Figures 3A-3F are illustrated using left-right folding as an example. In some embodiments, the inward-folding and outward-folding screens can also be folded vertically, and this application does not limit this.

[0169] Figures 3G-3L show schematic diagrams of the tri-fold screen display configuration.

[0170] Tri-fold screens can be divided into three display modes: unfolded, intermediate, and folded.

[0171] Figure 3G shows a schematic diagram of the display form of the tri-fold screen when it is in the unfolded state.

[0172] Figure 3G(a) exemplarily shows a front view of the tri-fold screen in its unfolded state. When unfolded, the tri-fold screen includes screens A, B, and C. The tri-fold screen also includes hinges D and E, which are used to rotate screens A, B, and C in the electronic device 10. Screens A and B can rotate along hinge D in opposite directions or facing directions until the back of screen A is flush with the back of screen B, or until the display surface of screen A is flush with the display surface of screen B. With screen C rotating at a constant angle, when screen B rotates along hinge D, screen B can cause screen C to rotate by the same angle along hinge D.

[0173] Screens C and B can rotate along hinge E in opposite directions or facing directions until the back of screen C is flush with the back of screen B, or until the display surface of screen C is flush with the display surface of screen B. With screen A rotating at a constant angle, when screen B rotates along hinge E, screen B can cause screen A to rotate by the same angle along hinge E.

[0174] In some embodiments, the angle between screen A and screen B can be called α, and the angle between screen B and screen C can be called β.

[0175] When the tri-fold screen is in the unfolded state, the display surfaces of screen A, screen B, and screen C of the electronic device 10 can all be on the same plane. The angle α between the display surfaces of screen A and screen B can be close to 180°, and the angle β between the display surfaces of screen B and screen C can be close to 180°.

[0176] In the front view shown in Figure 3G(a), the display screens of the electronic device 10 can be screen A, screen B and screen C from left to right.

[0177] Figure 3G(b) exemplarily shows the rear view of the tri-fold screen in the unfolded state.

[0178] When the tri-fold screen is unfolded, the backs of screen A, screen B, and screen C of the electronic device 10 can all be on the same plane. The angle between the back of screen A and the back of screen B can be close to 180°, and the angle between the back of screen B and the back of screen C can also be close to 180°.

[0179] Figure 3H shows a schematic diagram of the display form of the tri-fold screen when it is in the folded state.

[0180] Screens A and B can rotate in opposite directions along hinge D until the back of screen A is flush with the back of screen B. Screens C and B can rotate in opposite directions along hinge E until the display surface of screen C is flush with the display surface of screen B, thus putting the tri-fold screen in a folded state.

[0181] When the tri-fold screen is in the folded state, the angle α between the display surface of screen A and the display surface of screen B can be close to 360°, the angle between the back of screen A and the back of screen B can be close to 0°, the angle β between the display surface of screen B and the display surface of screen C can be close to 0°, and the angle between the back of screen B and the back of screen C can be close to 360°.

[0182] Figure 3H(a) shows a front view of the electronic device in the folded state. As shown in Figure 3H(a), when the tri-fold screen is in the folded state, the electronic device 10 only displays the display surface of screen A.

[0183] Figure 3H(b) shows the rear view of the electronic device in its fully folded state. As shown in Figure 3H(b), when the tri-fold screen is in the folded state, the electronic device 10 only displays the back of the C screen.

[0184] Figure 3I shows a schematic diagram of the display form of the tri-fold screen when it is in the folded state.

[0185] Folded states can include, but are not limited to, BC folded states, AB folded states, and BC folded states.

[0186] 1. When only the B screen and C screen are bonded together, it can also be called the BC folded state.

[0187] Screens C and B can rotate in the direction they face each other along the pivot E until the display surface of screen C and screen B are in contact, so that the tri-fold screen is in the BC folded state.

[0188] Figure 3I illustrates, for example, a schematic diagram of the display configuration of some electronic devices 10 in the BC folded state.

[0189] Figure 3I(a) shows a front view of the electronic device 10 in the BC folded state. As shown in Figure 3I(a), when the tri-fold screen is in the BC folded state, the electronic device 10 displays the display surface of screen A and the back surface of screen C. The angle α between the display surface of screen A and the display surface of screen B can be close to 180°. The angle β between the display surface of screen B and the display surface of screen C can be close to 0°, and the angle between the back surface of screen B and the back surface of screen C can be close to 360°.

[0190] Figure 3I(b) shows the rear view of the electronic device in the BC folded state. As shown in Figure 3I(b), when the tri-fold screen is in the BC folded state, the electronic device 10 displays the back of screen A and the back of screen B. The angle between the back of screen A and the back of screen B can be close to 180°.

[0191] 2. When only screens A and B are bonded together, it can also be called the AB folded state.

[0192] Screens A and B can rotate in opposite directions along pivot D until the back of screen A and the back of screen B are in contact, so that the tri-fold screen is in the AB folded state.

[0193] Figure 3J illustrates, for example, a schematic diagram of the display configuration of some electronic devices 10 in the AB folded state.

[0194] Figure 3J(a) shows a front view of the electronic device 10 in the AB folded state. As shown in Figure 3J(a), when the tri-fold screen is in the AB folded state, the electronic device 10 displays screen B and screen C. The angle β between screen B and screen C can be close to 180°.

[0195] Figure 3J(b) shows the rear view of the electronic device in the AB folded state. As shown in Figure 3J(b), when the tri-fold screen is in the AB folded state, the electronic device 10 displays the display surface of screen A and the back surface of screen C. The angle α between the display surface of screen A and the display surface of screen B can be close to 360°. The angle between the back surface of screen A and the back surface of screen B can be close to 0°. The angle between the back surface of screen B and the back surface of screen C can be close to 180°.

[0196] Figures 3K and 3L show schematic diagrams of the display form when the tri-fold screen is in the intermediate state.

[0197] Figure 3K shows a front view of the tri-fold screen in its intermediate state. As shown in Figure 3K, when the tri-fold screen is in its intermediate state, the electronic device 10 displays screen A, screen B, and screen C. The angle α between screen A and screen B can be between 180° and 360°. The angle β between screen B and screen C can be between 0° and 180°.

[0198] Figure 3L shows a rear view of the tri-fold screen in its intermediate state. As shown in Figure 3L, when the tri-fold screen is in its intermediate state, the electronic device 10 displays the back of screen A, the back of screen B, and the back of screen C. The angle between the back of screen A and the back of screen B can be between 0° and 180°. The angle between the back of screen B and the back of screen C can be between 180° and 360°.

[0199] Optionally, screens A, B, and C shown in Figures 3G-3L can be a single, complete display screen. Screens A and B can also be a single, complete display screen, as can screens B and C.

[0200] It should be noted that Figures 3G-3L only show some schematic diagrams of the display form of the tri-fold screen. The tri-fold screen can also be other display forms, and this application does not limit it.

[0201] Figures 3M-3O show schematic diagrams of the display configuration of the vertically folding screen.

[0202] The display forms of vertically folding screens can include, but are not limited to, unfolded, intermediate, and folded states.

[0203] Figure 3M shows a schematic diagram of the vertically folding screen in its unfolded state.

[0204] The vertically folding screen provided in this application can be either an outward-folding or inward-folding screen device. An outward-folding screen device folds the electronic device by folding it outwards, while an inward-folding screen device folds the electronic device by folding it inwards.

[0205] This application uses an inward-folding screen device as an example for illustration.

[0206] Figure 3M(a) shows a front view of the vertically folding screen in its unfolded state. As shown in Figure 3M(a), the vertically folding screen includes screen A, screen B, and folding line 101.

[0207] Optionally, screen A and screen B can be a single, complete display.

[0208] In the unfolded state, screens A and B face the user, and the angle between them is close to 180°, meaning that the plane containing screen A and the plane containing screen B are on the same horizontal plane. In the unfolded state, the electronic device 10 can display images on both screens A and B simultaneously. This allows the user to view images from both screens at the same time.

[0209] Figure 3M(b) shows a rear view of the electronic device 10 in its unfolded state. As shown in Figure 2, the electronic device 10 includes a camera module and a display screen.

[0210] When the vertically folding screen is in the unfolded state, the display is off and cannot be operated.

[0211] Figure 3N shows a schematic diagram of the vertically folding screen in its intermediate state.

[0212] As shown in Figure 3N, in the intermediate state, there is a certain angle between the plane where screen A is located and the plane where screen B is located, and this angle is greater than 0° and less than 180°.

[0213] In the intermediate state, electronic device 10 can display the image only on screen A or screen B. This allows the user to view only the image from screen A or screen B. Alternatively, electronic device 10 can display different images on screen A and screen B simultaneously. This allows the user to selectively view the image from screen A or screen B from both displays.

[0214] Figure 30 shows a schematic diagram of the vertically folding screen in the folded state.

[0215] As shown in Figure 30, in the folded state, the angle between the plane containing screen A and the plane containing screen B is close to 0°, and screens A and B are folded face to face.

[0216] In the folded state, screens A and B are no longer facing the user and cannot be displayed. Electronic device 10 can display images through the display screen.

[0217] When folded, the display is on and operable, for example, it can be used to display information such as time and date.

[0218] It should be noted that Figures 3A-3O above only illustrate several display forms of the display screen. The display screen of the electronic device 10 may also include other display forms, and this application does not limit them.

[0219] Taking a common flat screen as an example, the antenna of the electronic device 10 can be formed through a frame 11. The frame 11 may have gaps through which electromagnetic waves are radiated outward. The gaps can be filled with materials such as polymers, glass, ceramics, or combinations of these materials.

[0220] Figures 4A and 4B illustrate several implementation methods of antennas for electronic devices with flat screens using the bezel 11 in related technologies.

[0221] In one implementation, as exemplarily shown in Figure 4A, which is a front view of an electronic device, the electronic device 10 is equipped with four antennas for a specific frequency band (e.g., the N78 band of a cellular network, also known as a mobile network): a first antenna ANT1, a second antenna ANT2, a third antenna ANT3, and a seventh antenna ANT7. These are respectively located on the two sides of the top frame 11-5 of the electronic device 10, and on the upper half of the first side frame 11-1 and the second side frame 11-3. In the case of the antenna arrangement in the first related technology, the user's hand is less likely to be gripped or cover the gap when the phone is used in portrait mode. However, in the case of landscape mode, at least one antenna may be held by the hand, thus preventing four-antenna cellular communication and resulting in a significant decrease in communication performance. Referring to Figure 5A, which shows the electronic device 10 in landscape mode, the top is on the left-hand side when the phone is in landscape mode, and the left hand covers the first antenna ANT1, preventing four-antenna cellular communication.

[0222] Related Technology 2, as exemplified in Figure 4B, and Figure 4A being a front view of an electronic device, involves two antennas for a specific frequency band of Wi-Fi (e.g., the 5G Wi-Fi band): a first communication antenna (Wi-Fi C0) and a second communication antenna (Wi-Fi C1). These are respectively located on the right side of the top edge 11-5 and the upper half of the second side edge 11-3 of the electronic device 10. In the portrait mode of the phone, the antenna placement of Related Technology 2 prevents the user's hand from being gripped or covering the gap. However, in the landscape mode, at least one antenna may be held by the hand, thus preventing the two Wi-Fi antennas from communicating and resulting in a significant decrease in communication performance. Referring to Figure 5B, which shows the landscape mode of the electronic device 10, the top is on the right side, and the right hand covers the first communication antenna (Wi-Fi C0), preventing the two Wi-Fi antennas from communicating.

[0223] In addition, in some related technologies, the antenna is also placed on the bottom frame 11-7 of the electronic device 10, but for the bottom antenna, the user may also cover part of the antenna in the usage scenarios shown in Figures 5A and 5B.

[0224] It is understandable that Figures 5A and 5B only show a common scenario of holding the screen horizontally with both hands. In actual use of electronic devices, there are many other holding postures, and the antenna blockage of a certain frequency band is also different. They will not be shown one by one here, nor will they be limited.

[0225] Therefore, it is evident that in related technologies, the layout of cellular or Wi-Fi antennas for a specific frequency band is primarily concentrated on the top, upper half, and bottom of the bezel of the electronic device 10. In some landscape usage scenarios, cellular antennas cannot achieve simultaneous unobstructed access for all four antennas, and Wi-Fi antennas cannot achieve simultaneous unobstructed access for both antennas, resulting in poor communication quality for the electronic device 10. This severely impacts the user's landscape usage experience, such as gaming, especially for games with high latency requirements.

[0226] This application provides an antenna system for an electronic device. This system is an intelligent multi-antenna scheme that deploys antennas on both the frame and the back cover of the electronic device 10 for a specific frequency band (e.g., the N78 band of cellular Sub 6G or the 5G band of WIFI). These antennas form a frame antenna group and a back cover antenna group, respectively. The frame antenna group can further include a top frame group and a side frame group. This system takes into account antenna performance in various scenarios, such as free space scenarios, portrait screen holding scenarios, and landscape screen holding scenarios, thereby improving antenna radiation efficiency and enhancing the communication quality of the electronic device in different usage scenarios.

[0227] Figure 6 illustrates a schematic diagram of the possible placement positions of the antenna system provided in this application in an electronic device. As shown in Figure 6, which is a rear view of the electronic device, it includes a frame 11 and a back cover 12 (the blank part within the frame is the back cover). The frame 11 is divided into a top frame 11-5, a first side frame 11-1, a second side frame 11-3, and a bottom frame 11-7. Therefore, a frame antenna group can be arranged on the frame 11. Simultaneously, in this embodiment, a back cover antenna group can be arranged on the back cover 12. It is understood that when facing a landscape usage scenario, the frame antenna group is more likely to be obstructed because the user's grip posture covers the frame. In contrast, the back cover antenna group has more space to be placed and is easier to avoid areas that are easily gripped. Therefore, the combination of the back cover antenna group and the frame antenna group can improve the communication quality of the electronic device 10 in different usage scenarios.

[0228] It is understandable that the frame antenna of the frame antenna group can achieve antenna function by using gaps opened on the frame and setting up feeding points. The rear cover antenna of the rear cover antenna group can be attached to the rear cover, specifically in at least two ways: one is that the antenna structure is attached to an insulating support, and the other is that the antenna structure is attached to an insulating area of ​​the rear cover (e.g., the inner or outer surface of the rear cover or embedded in the rear cover). Therefore, the rear cover antenna group described in this application, which is arranged on the rear cover, can be understood to include both of the above situations.

[0229] It should be noted that, in the embodiments of this application, the front of the electronic device 10 is the side where the screen is located. If it is a foldable device, the front is the side where the main screen is located after the foldable device is unfolded. Correspondingly, the side opposite to the front is the back. For the electronic device 10, there may or may not be a camera area (hereinafter referred to as camera) on the back cover 12.

[0230] To define the antenna position in subsequent embodiments, we first take a flat screen as an example and divide the size of the back cover 12 area of ​​the electronic device 10. Refer to Figure 7, which is a schematic diagram of the size division of the back cover of the electronic device. As shown in Figures 6 and 7, Figure 7 is a schematic diagram of the cover plate under the rear view of the electronic device. The back cover 12 in the figure includes a long side and a short side. Generally, the short side is the edge of the back cover 12 corresponding to the position of the top frame 11-5 or the bottom frame 11-7 of the electronic device 10, i.e., the first short side and the second short side in the figure; the long side is the edge of the back cover 12 corresponding to the position of the first side frame 11-1 or the second side frame 11-3 of the electronic device 10, i.e., the first long side and the second long side in the figure. In this embodiment, it can be considered that the first long side and the second long side abut against the first side frame and the second side frame, respectively. The distance from a point on the back cover 12 to the first long side or the second long side is the distance to the first side frame or the second side frame. Similarly, the distance from a point on the back cover 12 to the first short side or the second short side is the distance to the top frame or the bottom frame. The camera is usually located near the top of the electronic device.

[0231] It should be noted that in physical electronic devices, the edge line of the back cover 12 is not necessarily a strictly straight line. Therefore, when determining the long or short side of the back cover 12, it can also be obtained by fitting line segments. In addition, there may be a smooth chamfer at the connection point between adjacent long and short sides. In this case, the straight line segment of the long or short side can be extended to the intersection point to determine the beginning and end of the long or short side, thus clearly obtaining the dimensional boundaries. As shown in Figure 7, assuming the distance between the first and second long sides is 2b and the distance between the first and second short sides is 2a, where a and b are both positive numbers, then b is the perpendicular distance from the first or second short side to the midline of the long side, and a is the perpendicular distance from the second or first long side to the midline of the short side. The midline of the long side is the perpendicular bisector of the first or second long side, and the midline of the short side is the perpendicular bisector of the first or second short side. It should be noted that if the length value of the border is determined according to the aforementioned method for determining the long side and the short side, then 2a can also be defined as the length value of the top border 11-5 or the bottom border 11-7, and 2b can be defined as the length value of the first side border 11-1 or the second side border 11-3.

[0232] The following shows several embodiments of the antenna system provided in this application, and provides a detailed description of the layout of the rear cover antenna group and the frame antenna group.

[0233] Figures 8A, 8B, 8C, and 8D show rear views of an electronic device 10. This embodiment provides an antenna system for the electronic device 10. In one embodiment, the antenna system serves a frequency band of 2GHz-10GHz. For example, the antenna system serves the high-frequency band of Sub-6G in a cellular network (e.g., 3000MHz to 6000MHz). The antenna system includes: a first frame antenna group, a first rear cover antenna group, and an antenna control device (not shown). The first frame antenna group is disposed on the frame 11, and the first rear cover antenna group is disposed on the rear cover 12. The antenna control device is connected to the antennas in the first frame antenna group and the first rear cover antenna group.

[0234] The first frame antenna group includes: a first antenna ANT1, a second antenna ANT2, and a third antenna ANT3. The first rear cover antenna group includes: a fourth antenna ANT4, a fifth antenna ANT5, and a sixth antenna. In one embodiment, the sixth antenna includes at least one of a first sub-antenna ANT6-1 or a second sub-antenna ANT6-2. In the embodiments of this application, the corresponding antennas are referred to as ANT1, ANT2, ANT3, ANT4, ANT5, ANT6-1, and ANT6-2 in the accompanying drawings.

[0235] The first antenna ANT1 can be located in the middle of the top frame 11-5, or it can be located near the second side frame 11-3 relative to the first side frame 11-1. The second antenna ANT2 and the third antenna ANT3 are located in the upper half of the second side frame 11-3 and the first side frame 11-1, respectively. The upper half refers to the half of the second side frame 11-3 and the first side frame 11-1 near the top frame 11-5. The middle position of the top frame 11-5 can be understood as the distance range formed by extending a certain distance (e.g., 20mm) from the vertical line of the top frame 11-5 towards the first side frame 11-1 and the second side frame 11-3. The feed point of the first antenna ANT1 can be located within this distance range.

[0236] The minimum distance value between the radiator of the fourth antenna ANT4 and the top frame 11-5 is D1, and the minimum distance value between the radiator of the fourth antenna ANT4 and the first side frame 11-1 is D4; the minimum distance value between the radiator of the fifth antenna ANT5 and the top frame 11-5 is D3, and the minimum distance value between the radiator of the fifth antenna ANT5 and the second side frame 11-3 is D2; the minimum distance value between the radiator of the sixth antenna and the second side frame 11-3 is at least 3 mm, and the minimum distance value between the radiator of the sixth antenna and the top frame 11-5 is at least 20 mm; or, the minimum distance value between the radiator of the sixth antenna and the first side frame 11-1 is at least 3 mm, and the minimum distance value between the radiator of the sixth antenna and the top frame 11-5 is at least 20 mm. Wherein, 0<D1<25mm, 0<D2<a, 0<D3<25mm, 0<D4<a, and a is half of the length value of the top frame 11-5 or the bottom frame 11-7. In one embodiment, the minimum distance value between the radiator of the first sub-antenna ANT6-1 and the second side frame 11-3 is at least 3 mm, and the minimum distance value between the radiator of the first sub-antenna ANT6-1 and the top frame 11-5 is at least 20 mm. In one embodiment, the minimum distance value between the radiator of the second sub-antenna ANT6-2 and the first side frame 11-1 is at least 3 mm, and the minimum distance value between the radiator of the second sub-antenna ANT6-2 and the top frame 11-5 is at least 20 mm. It can be understood that the relative distance between the fourth antenna ANT4 and the fifth antenna ANT5 also needs to meet the isolation requirement.

[0237] In this embodiment, the arrangement of at least six antennas can achieve that in most scenarios of horizontal and vertical screens, at least four antennas can be prevented from being held simultaneously. Therefore, four antennas with better signal quality can be selected for cellular network communication, thereby improving the performance of the antenna system.

[0238] As an optional embodiment, the antenna control device is used to control the switching of at least one antenna among the first antenna ANT1, the fourth antenna ANT4, the fifth antenna ANT5, and the sixth antenna.

[0239] Specifically, when the electronic device is in the horizontal screen state, the antenna control device is used to control the second antenna, the third antenna, and the sixth antenna as the target communication antennas; the antenna control device is also used to control one antenna among the first antenna, the fourth antenna, and the fifth antenna as the target communication antenna, so as to form at least four antennas as the target communication antennas.

[0240] and / or,

[0241] When the electronic device is in portrait mode, the antenna control device is used to control the first antenna, the second antenna, and the third antenna as target communication antennas; the antenna control device is also used to control one of the fourth antenna and the fifth antenna as a target communication antenna.

[0242] It is understood that in the embodiments of this application, the electronic device in portrait mode can be understood as the electronic device being used in a portrait mode scenario; similarly, the electronic device in landscape mode can be understood as the electronic device being used in a landscape mode scenario.

[0243] As shown in Figures 8A to 8D, the configuration and switching of the six antennas in this embodiment can be as follows:

[0244] In portrait mode usage scenarios, the first antenna ANT1, the second antenna ANT2, and the third antenna ANT3 of the bezel antenna group, and the fourth antenna ANT4 or the fifth antenna ANT5 of the rear cover antenna group can be selected. In portrait mode usage, the lower half of the electronic device is typically held with one or both hands. Therefore, the first antenna ANT1, the second antenna ANT2, and the third antenna ANT3, located on the upper half of the bezel, have high radiation efficiency. The fourth antenna ANT4 and the fifth antenna ANT5, being located on the upper part of the rear cover, can be selected considering both radiation efficiency and antenna directivity. Antennas with their receiving direction aligned with the direction of incoming waves from the base station perform better. Antenna switching can be achieved through an antenna switching switch. As an optional embodiment, in this embodiment, in the portrait mode usage scenario, the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the fourth antenna ANT4 are selected as the target communication antennas. The target communication antenna refers to the antenna whose frequency band is specified for operation in this scenario.

[0245] In landscape mode, the top bezel 11-5 is located on the left, allowing for single-handed or two-handed use, such as in two-handed gaming scenarios. Referring to Figure 8C, which is a schematic diagram of a front-facing electronic device with the antenna system of this embodiment in a two-handed landscape mode (top bezel on the left), both the first antenna ANT1 and the fifth antenna ANT5 are easily held when gripped with both hands or only the left hand. Therefore, the second antenna ANT2, the third antenna ANT3, the fourth antenna ANT4, and the first sub-antenna ANT6-1 (or the second sub-antenna ANT6-2) can be selected as the target communication antenna. The antenna switching switch can be used to switch the first antenna ANT1 connected in portrait mode to the first sub-antenna ANT6-1 (or the second sub-antenna ANT6-2), or the selection and switching can be performed according to the antenna control method in subsequent embodiments.

[0246] In landscape mode, the top bezel 11-5 is located on the right-hand side, allowing for single-handed or double-handed use. Referring to Figure 8D, which is a schematic diagram of a front-facing landscape mode (top bezel on the right-hand side) of an electronic device with the antenna system according to this embodiment, the fourth antenna ANT4 is easily held when gripped with both hands or only the right hand. The first antenna ANT1 and the fifth antenna ANT5 may be held in certain gripping postures; for example, in some gripping scenarios, the first antenna ANT1 in Figure 8D may be held by the index finger. Therefore, switching or tuning can be performed according to the antenna control method of the following embodiments. Thus, in this scenario, the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the first sub-antenna ANT6-1 (or the second sub-antenna ANT6-2) may be selected, or the second antenna ANT2, the third antenna ANT3, the fifth antenna ANT5, and the first sub-antenna ANT6-1 (or the second sub-antenna ANT6-2) may be selected. Antenna switching can be achieved through an antenna switching switch.

[0247] It should be noted that the accompanying drawings of the embodiments of this application use a conductive frame formed of conductive material as an example. Therefore, the frame antennas in the drawings are only shown to indicate their relative positions. For example, the radiator of the third antenna ANT3 in Figures 8A to 8D can be part or all of the frame body between the two gaps.

[0248] Furthermore, the possible ways in which electronic devices can be held cannot be exhaustively listed in this embodiment. However, the antenna layout of the antenna system in this embodiment can avoid the user's hand grip in most usage scenarios, ensuring that at least four antennas are not held simultaneously.

[0249] Therefore, it can be seen that the antenna system of this embodiment can ensure that at least four antennas are not simultaneously blocked (or held) in most usage scenarios, whether in portrait or landscape mode. This improves the overall communication performance of the electronic device in various scenarios, resulting in a better user experience.

[0250] As shown in Figure 8E, Figure 8E provides another layout of the antenna system. Based on the antenna system of the previous embodiment, the sixth antenna includes two sub-antennas, namely the first sub-antenna ANT6-1 and the second sub-antenna ANT6-2. The situation of the remaining antennas and the positional relationship of the antennas can be referred to the previous embodiment.

[0251] As an optional embodiment, the antenna control device is used to control the switching of at least one of the first antenna, fourth antenna, fifth antenna, first sub-antenna and second sub-antenna.

[0252] Specifically, as shown in Figure 8E, the configuration and switching of the 7 antennas in this embodiment can be as follows:

[0253] In portrait mode usage scenarios, the first antenna ANT1, the second antenna ANT2, and the third antenna ANT3 of the bezel antenna group, and the fourth antenna ANT4 or the fifth antenna ANT5 of the rear cover antenna group can be selected. In portrait mode usage, the lower half of the electronic device is typically held with one or both hands. Therefore, the first antenna ANT1, the second antenna ANT2, and the third antenna ANT3, located on the upper half of the bezel, have high radiation efficiency. The fourth antenna ANT4 and the fifth antenna ANT5, being located on the upper part of the rear cover, can be selected considering both radiation efficiency and antenna directivity. Antennas with their receiving direction aligned with the direction of incoming waves from the base station perform better. Antenna switching can be achieved through an antenna switching switch. As an optional embodiment, in this embodiment, in the portrait mode usage scenario, the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the fourth antenna ANT4 are selected as the target communication antennas. The target communication antenna refers to the antenna whose frequency band is specified for operation in this scenario.

[0254] In landscape mode, with the top bezel 11-5 positioned to the left, it can be used with one or both hands, such as in a two-handed gaming scenario. Referring to Figure 8C, which is a schematic diagram of a front-facing electronic device with the antenna system of this embodiment in a two-handed landscape mode (top bezel to the left), when held with both hands or only the left hand, the first antenna ANT1 and the fifth antenna ANT5 are easily held. Therefore, the first sub-antenna ANT6-1 and the second sub-antenna ANT6-2 are generally not held. However, since the second sub-antenna ANT6-2 is located at the top in landscape mode, its antenna directivity is generally better. The fourth antenna ANT4 may be held by the user's index or middle finger in some scenarios (such as some games). Therefore, the second antenna ANT2, the third antenna ANT3, and the second sub-antenna ANT6-2 can be selected as the target communication antennas. The first sub-antenna ANT6-1 and the fourth antenna ANT4 can be selected according to the antenna control method in subsequent embodiments, thereby selecting four target communication antennas to operate. Antenna switching can be achieved through an antenna switching switch.

[0255] In landscape mode, with the top bezel positioned to the right, it can be used with one or both hands. When holding the device with both hands or only the right hand, the fourth antenna ANT4 is easily gripped. The first antenna ANT1 and the fifth antenna ANT5 may be gripped by the user's index or middle finger in some scenarios (such as some games). The first sub-antenna ANT6-1 and the second sub-antenna ANT6-2 are generally not gripped, but the first sub-antenna ANT6-1, located at the top in landscape mode, generally has better antenna directivity. Therefore, the second antenna ANT2, the third antenna ANT3, and the first sub-antenna ANT6-1 can be selected as the target communication antennas. The first antenna ANT1, the fifth antenna ANT5, and the second sub-antenna ANT6-2 can be selected and switched according to the antenna control method in subsequent embodiments, selecting one of them to select four target communication antennas for operation.

[0256] Therefore, it can be seen that the antenna system of this embodiment can ensure that at least four antennas are not simultaneously blocked (or held) in most usage scenarios, whether in portrait or landscape mode. This improves the overall communication performance of the electronic device in various scenarios, resulting in a better user experience.

[0257] Figure 9A shows a rear view of an electronic device 10, providing an antenna system for the electronic device 10. In one embodiment, the antenna system has a frequency band range of 2GHz-10GHz. For example, the antenna system serves the high-frequency band of a cellular network Sub-6G (e.g., 3000MHz to 6000MHz). The antenna system includes: a first frame antenna group, a first rear cover antenna group, and an antenna control device (not shown). The first frame antenna group is disposed on a frame 11, and the first rear cover antenna group is disposed on a rear cover 12. The antenna control device is connected to the antennas in the first frame antenna group and the first rear cover antenna group.

[0258] The first frame antenna group includes: a first antenna ANT1, a second antenna ANT2, a third antenna ANT3, and a seventh antenna ANT7. Based on the aforementioned embodiment, the first frame antenna group adds a seventh antenna ANT7. In the accompanying drawings, the corresponding antennas are represented by ANT1, ANT2, ANT3, and ANT7, respectively.

[0259] The first rear cover antenna group can include the layout described in the above embodiment. Alternatively, the first rear cover antenna group can also have the following layout:

[0260] The first rear cover antenna group includes a fourth antenna and a sixth antenna. In the accompanying drawings, the fourth antenna is denoted by ANT4. In one embodiment, the sixth antenna includes a first sub-antenna ANT6-1 or a second sub-antenna ANT6-2.

[0261] Among them, the first antenna ANT1 can be located at a position closer to the second side frame 11-3 relative to the first side frame 11-1; the seventh antenna ANT7 can be located at a position closer to the first side frame 11-1 relative to the second side frame 11-3; the second antenna ANT2 and the third antenna ANT3 are respectively located in the upper half parts on the second side frame 11-3 and the first side frame 11-1.

[0262] The minimum distance value between the radiator of the fourth antenna ANT4 and the top frame 11-5 is D1, and the minimum distance value between the radiator of the fourth antenna ANT4 and the first side frame 11-1 is D4; the minimum distance value between the radiator of the first sub-antenna ANT6-1 and the second side frame 11-3 is at least 3 mm, and the minimum distance value between the radiator of the first sub-antenna ANT6-1 and the top frame 11-5 is at least 20 mm; or, the minimum distance value between the radiator of the second sub-antenna ANT6-2 and the first side frame 11-1 is at least 3 mm, and the minimum distance value between the radiator of the second sub-antenna ANT6-2 and the top frame 11-5 is at least 20 mm; where 0 < D1 < 25 mm, 0 < D2 < a, 0 < D3 < 25 mm, 0 < D4 < a, and a is half of the length value of the top frame 11-5 or the bottom frame 11-7.

[0263] As shown in FIG. 9A, only the case including the fourth antenna ANT4 and the second sub-antenna ANT6-2 is exemplarily shown in FIG. 9A, and the first sub-antenna ANT6-1 can be referred to.

[0264] In this embodiment, the setting of the 6 antennas can enable at least four antennas not to be held simultaneously in most scenarios of portrait and landscape screens. Therefore, 4 antennas with better signal quality can be selected for cellular network communication, thereby improving the performance of the antenna system. Specifically, the configuration of the 6 antennas in this embodiment can be as follows:

[0265] In the portrait screen usage scenario, the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the seventh antenna ANT7 of the frame antenna group can be selected as the target communication antennas. When using the portrait screen, generally, the lower half of the electronic device is held with one hand or both hands. Therefore, the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the seventh antenna ANT7 located in the upper half part of the frame have high radiation efficiency, and the switching of the antennas can be realized through an antenna switching switch.

[0266] In landscape mode, with the top bezel 11-5 positioned to the left, it can be used with one or both hands. Similar to the hand grip shown in Figure 8C, when held with both hands or only the left hand, the first antenna ANT1 is easily gripped. The fourth antenna ANT4 and the seventh antenna ANT7 may be gripped in certain holding postures; for example, in some scenarios, the seventh antenna ANT7 might be gripped by the index finger. Therefore, the second antenna ANT2, the third antenna ANT3, and the first sub-antenna ANT6-1 (or the second sub-antenna ANT6-2) can be selected. The fourth antenna ANT4 and the seventh antenna ANT7 can be switched or tuned according to the antenna control method in subsequent embodiments, thereby selecting four target communication antennas to operate. This is applicable to scenarios such as two-handed gaming.

[0267] In landscape mode, with the top bezel 11-5 positioned to the right, it can be used with one or both hands. Similar to the hand grip shown in Figure 8D, when gripped with both hands or only the right hand, the fourth antenna ANT4 and the seventh antenna ANT7 are easily held. Therefore, in this scenario, the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the first sub-antenna ANT6-1 (or the second sub-antenna ANT6-2) can be selected as the target communication antennas.

[0268] It should be noted that the possible ways in which an electronic device can be held cannot be exhaustively listed in this embodiment. However, the antenna layout of the antenna system in this embodiment can avoid the user's hand grip in most usage scenarios, ensuring that at least four antennas are not held simultaneously.

[0269] Therefore, it can be seen that the antenna system of this embodiment can ensure that at least four antennas are not simultaneously blocked (or held) in most usage scenarios, whether in portrait or landscape mode. This improves the overall communication performance of the electronic device in various scenarios, resulting in a better user experience.

[0270] Figure 9B shows a rear view of an electronic device 10, providing an antenna system for the electronic device 10. In one embodiment, the antenna system serves a frequency band ranging from 2 GHz to 10 GHz. For example, the antenna system serves a high-frequency band (e.g., 3000 MHz to 6000 MHz) of the Sub-6 GHz cellular network. The antenna system includes: a first frame antenna group, a first rear cover antenna group, and an antenna control device (not shown). The first frame antenna group is disposed on a frame 11, and the first rear cover antenna group is disposed on a rear cover 12. The antenna control device is connected to the antennas in the first frame antenna group and the first rear cover antenna group.

[0271] The first frame antenna group includes: the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the seventh antenna ANT7. On the basis of the foregoing embodiment, the seventh antenna ANT7 is added to the first frame antenna group, and the corresponding antennas are respectively represented by ANT1, ANT2, ANT3, and ANT7 in the drawings.

[0272] The first rear cover antenna group may include the layout of the foregoing embodiment. In one embodiment, the first rear cover antenna group may also be the following layout:

[0273] The first rear cover antenna group includes: the fifth antenna and the sixth antenna, and the corresponding antenna of the fifth antenna is represented by ANT5 in the drawings. In one embodiment, the sixth antenna includes the first sub-antenna ANT6-1 or the second sub-antenna ANT6-2.

[0274] Among them, the first antenna ANT1 may be located at a position closer to the second side frame 11-3 relative to the first side frame 11-1; the seventh antenna ANT7 may be located at a position closer to the first side frame 11-1 relative to the second side frame 11-3; the second antenna ANT2 and the third antenna ANT3 are respectively located in the upper half parts on the second side frame 11-3 and the first side frame 11-1.

[0275] The minimum distance value between the radiator of the fourth antenna ANT4 and the top frame 11-5 is D1, and the minimum distance value between the radiator of the fourth antenna ANT4 and the first side frame 11-1 is D4; the minimum distance value between the radiator of the fifth antenna ANT5 and the top frame 11-5 is D3, and the minimum distance value between the radiator of the fifth antenna ANT5 and the second side frame 11-3 is D2; the minimum distance value between the radiator of the first sub-antenna ANT6-1 and the second side frame 11-3 is at least 3 mm, and the minimum distance value between the radiator of the first sub-antenna ANT6-1 and the top frame 11-5 is at least 20 mm; or, the minimum distance value between the radiator of the second sub-antenna ANT6-2 and the first side frame 11-1 is at least 3 mm, and the minimum distance value between the radiator of the second sub-antenna ANT6-2 and the top frame 11-5 is at least 20 mm; where, 0 < D1 < 25 mm, 0 < D2 < a, 0 < D3 < 25 mm, 0 < D4 < a, and a is half of the length value of the top frame 11-5 or the bottom frame 11-7.

[0276] As shown in FIG. 9B, only the case including the fifth antenna ANT5 and the second sub-antenna ANT6-2 is exemplarily shown in FIG. 9B, and the first sub-antenna ANT6-1 can be referred to.

[0277] In this embodiment, the configuration of six antennas ensures that at least four antennas are not simultaneously held in most scenarios involving both portrait and landscape screens. Therefore, the four antennas with the best signal quality can be selected for cellular network communication, thereby improving the performance of the antenna system. Specifically, the configuration of the six antennas in this embodiment is as follows:

[0278] In portrait mode, the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the seventh antenna ANT7 of the bezel antenna group can be selected as the target communication antenna. In portrait mode, the lower half of the electronic device is usually held with one or both hands. Therefore, the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the seventh antenna ANT7 located in the upper half of the bezel have high radiation efficiency. Antenna switching can be achieved through an antenna switching switch.

[0279] In landscape mode, with the top bezel 11-5 positioned to the left, it can be used with one or both hands. Similar to the hand grip shown in Figure 8C, when gripped with both hands or only the left hand, the first antenna ANT1 and the fifth antenna ANT5 are easily held. Therefore, the second antenna ANT2, the third antenna ANT3, the seventh antenna ANT7, and the first sub-antenna ANT6-1 (or the second sub-antenna ANT6-2) can be selected as the four target communication antennas. For example, in a two-handed gaming scenario. In other scenarios, when the left hand only grips the bezel, i.e., only the first antenna ANT1 is held, the second antenna ANT2, the third antenna ANT3, and the fifth antenna ANT5 are selected. In some cases, the seventh antenna ANT7 may also be held by the index finger. Therefore, the first sub-antenna ANT6-1 (or the second sub-antenna ANT6-2) and the seventh antenna ANT7 can be switched or tuned according to the antenna control method in subsequent embodiments, thereby selecting the four target communication antennas to operate.

[0280] In landscape mode, with the top bezel 11-5 positioned to the right, it can be used with one or both hands. Similar to the hand grip shown in Figure 8D, when gripped with both hands or only the right hand, the seventh antenna ANT7 is easily held. In some cases, the first antenna ANT1 and the fifth antenna ANT5 may also be held by the index finger. Therefore, the second antenna ANT2, the third antenna ANT3, and the first sub-antenna ANT6-1 (or the second sub-antenna ANT6-2) are selected. The first antenna ANT1 and the fifth antenna ANT5 can be switched or tuned according to the antenna control method in subsequent embodiments, thereby selecting four target communication antennas to operate. In other scenarios, when the right hand only grips the bezel, only the first antenna ANT1 may be held. Therefore, among the second antenna ANT2, the third antenna ANT3, the fifth antenna ANT5, the seventh antenna ANT7, and the first sub-antenna ANT6-1 (or the second sub-antenna ANT6-2), the bezel antenna with better radiation efficiency can be selected as the four target communication antennas, i.e., the second antenna ANT2, the third antenna ANT3, the fifth antenna ANT5, and the seventh antenna ANT7.

[0281] It should be noted that the possible ways in which an electronic device can be held cannot be exhaustively listed in this embodiment. However, the antenna layout of the antenna system in this embodiment can avoid the user's hand grip in most usage scenarios, ensuring that at least four antennas are not held simultaneously.

[0282] Therefore, it can be seen that the antenna system of this embodiment can ensure that at least four antennas are not simultaneously blocked (or held) in most usage scenarios, whether in portrait or landscape mode. This improves the overall communication performance of the electronic device in various scenarios, resulting in a better user experience.

[0283] Figure 9C shows a rear view of an electronic device 10, providing an antenna system for the electronic device 10. In one embodiment, the antenna system serves a frequency band ranging from 2 GHz to 10 GHz. For example, the antenna system serves a high-frequency band (e.g., 3000 MHz to 6000 MHz) in the Sub-6 GHz range of a cellular network. The antenna system includes: a first frame antenna group, a first rear cover antenna group, and an antenna control device (not shown). The first frame antenna group is disposed on a frame 11, and the first rear cover antenna group is disposed on a rear cover 12. The antenna control device is connected to the antennas in the first frame antenna group and the first rear cover antenna group.

[0284] The first frame antenna group includes: a first antenna ANT1, a second antenna ANT2, a third antenna ANT3, and a seventh antenna ANT7. Based on the aforementioned embodiment, the first frame antenna group adds a seventh antenna ANT7. In the accompanying drawings, the corresponding antennas are represented by ANT1, ANT2, ANT3, and ANT7, respectively.

[0285] The first rear cover antenna group includes: the fourth antenna, the fifth antenna, and the sixth antenna. In the attached drawings, the fourth antenna is represented by ANT4 for the corresponding antenna, and the fifth antenna is represented by ANT5 for the corresponding antenna. In one embodiment, the sixth antenna includes a first sub-antenna ANT6-1 and a second sub-antenna ANT6-2.

[0286] Among them, the first antenna ANT1 can be located at a position closer to the second side frame 11-3 relative to the first side frame 11-1; the seventh antenna ANT7 can be located at a position closer to the first side frame 11-1 relative to the second side frame 11-3; the second antenna ANT2 and the third antenna ANT3 are respectively located in the upper half parts on the second side frame 11-3 and the first side frame 11-1.

[0287] The minimum distance value between the radiator of the fourth antenna ANT4 and the top frame 11-5 is D1, and the minimum distance value between the radiator of the fourth antenna ANT4 and the first side frame 11-1 is D4; the minimum distance value between the radiator of the fifth antenna ANT5 and the top frame 11-5 is D3, and the minimum distance value between the radiator of the fifth antenna ANT5 and the second side frame 11-3 is D2; the minimum distance value between the radiator of the first sub-antenna ANT6-1 and the second side frame 11-3 is at least 3 mm, and the minimum distance value between the radiator of the first sub-antenna ANT6-1 and the top frame 11-5 is at least 20 mm; the minimum distance value between the radiator of the second sub-antenna ANT6-2 and the first side frame 11-1 is at least 3 mm, and the minimum distance value between the radiator of the second sub-antenna ANT6-2 and the top frame 11-5 is at least 20 mm; where 0 < D1 < 25 mm, 0 < D2 < a, 0 < D3 < 25 mm, 0 < D4 < a, and a is half of the length value of the top frame 11-5 or the bottom frame 11-7.

[0288] In this embodiment, the setting of 8 antennas can achieve that in most scenarios of portrait and landscape screens, at least four antennas can be prevented from being held simultaneously. Therefore, 4 antennas with better signal quality can be selected for cellular network communication, thereby improving the performance of the antenna system. Specifically, the configuration of the 8 antennas in this embodiment can be as follows:

[0289] In the portrait screen usage scenario, the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the seventh antenna ANT7 of the frame antenna group can be selected as the target communication antennas. When using the portrait screen, generally hold the lower half of the electronic device with one hand or both hands. Therefore, the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the seventh antenna ANT7 located in the upper half of the frame have high radiation efficiency, and the switching of the antennas can be realized through an antenna switching switch.

[0290] In landscape mode, with the top bezel 11-5 positioned to the left, it can be used with one or both hands. Similar to the hand grip shown in Figure 8C, when gripped with both hands or only the left hand, the first antenna ANT1 and the fifth antenna ANT5 are easily held. In some cases, the fourth antenna ANT4 and the seventh antenna ANT7 may also be held by the index or middle finger (e.g., in some gaming scenarios). Therefore, the second antenna ANT2, the third antenna ANT3, the first sub-antenna ANT6-1, and the second sub-antenna ANT6-2 can be selected as four target communication antennas. Antenna switching can be achieved using an antenna switching switch.

[0291] In landscape mode, with the top bezel 11-5 positioned to the right, it can be used with one or both hands. Similar to the hand grip shown in Figure 8D, when gripped with both hands or only the right hand, the fourth antenna ANT4 and the seventh antenna ANT7 are easily held. In some cases, the first antenna ANT1 and the fifth antenna ANT5 may also be held by the index or middle finger (e.g., in some gaming scenarios). Therefore, the second antenna ANT2, the third antenna ANT3, the first sub-antenna ANT6-1, and the second sub-antenna ANT6-2 can be selected as the four target communication antennas. Antenna switching can be achieved using an antenna switching switch.

[0292] In one embodiment, if the fourth antenna ANT4 or the fifth antenna ANT5 is not held, the rear cover antenna group can be switched or tuned according to the antenna control method of a subsequent embodiment.

[0293] It should be noted that the possible ways in which an electronic device can be held cannot be exhaustively listed in this embodiment. However, the antenna layout of the antenna system in this embodiment can avoid the user's hand grip in most usage scenarios, ensuring that at least four antennas are not held simultaneously.

[0294] Therefore, it can be seen that the antenna system of this embodiment can ensure that at least four antennas are not simultaneously blocked (or held) in most usage scenarios, whether in portrait or landscape mode. This improves the overall communication performance of the electronic device in various scenarios, resulting in a better user experience.

[0295] Figures 10A, 10B, and 10C show a rear view of an electronic device 10, providing an antenna system for the electronic device 10. In one embodiment, the antenna system serves a frequency band ranging from 2 GHz to 10 GHz. For example, the antenna system serves a high-frequency band (e.g., 3000 MHz to 6000 MHz) of a cellular network Sub-6G. The antenna system includes: a first frame antenna group, a first rear cover antenna group, and an antenna control device (not shown). The first frame antenna group is disposed on a frame 11, and the first rear cover antenna group is disposed on a rear cover 12. The antenna control device is connected to the antennas in the first frame antenna group and the first rear cover antenna group.

[0296] The first frame antenna group includes: a first antenna, a second antenna, a third antenna, a seventh antenna, and an eighth antenna. Based on the aforementioned embodiment, the first frame antenna group adds an eighth antenna, which is represented by ANT1, ANT2, ANT3, ANT7, and ANT8 in the accompanying drawings.

[0297] The first rear cover antenna group may include the layout of the first rear cover antenna group in the foregoing embodiments. In one embodiment, the first rear cover antenna group may also have the following layout:

[0298] As shown in Figures 10A to 10C, the first rear cover antenna group includes a sixth antenna. In one embodiment, the sixth antenna includes a first sub-antenna ANT6-1 or a second sub-antenna ANT6-2. Alternatively, in another embodiment, the sixth antenna includes a first sub-antenna ANT6-1 and a second sub-antenna ANT6-2.

[0299] The first antenna ANT1 can be located near the second side frame 11-3 relative to the first side frame 11-1; the seventh antenna ANT7 can be located near the first side frame 11-1 relative to the second side frame 11-3; the eighth antenna ANT8 is located in the middle of the first side frame 11-1; the second antenna ANT2 and the third antenna ANT3 are located in the upper half of the second side frame 11-3 and the first side frame 11-1, respectively; the upper half refers to the half of the second side frame 11-3 and the first side frame 11-1 near the top frame 11-5; the middle of the first side frame 11-1 can be understood as the distance range formed by extending 20mm from the vertical line of the first side frame 11-1 towards the top frame 11-5 and the bottom frame 11-7, respectively, and the feed point of the eighth antenna ANT8 can be located within this distance range.

[0300] The minimum distance between the radiator of the first sub-antenna ANT6-1 and the second side frame 11-3 is at least 3 mm, and the minimum distance between the radiator of the first sub-antenna ANT6-1 and the top frame 11-5 is at least 20 mm; the minimum distance between the radiator of the second sub-antenna ANT6-2 and the first side frame 11-1 is at least 3 mm, and the minimum distance between the radiator of the second sub-antenna ANT6-2 and the top frame 11-5 is at least 20 mm.

[0301] In this embodiment, the configuration of 6 or 7 antennas ensures that at least four antennas are not simultaneously held in most scenarios involving both portrait and landscape screens. Therefore, the four antennas with the best signal quality can be selected for cellular network communication, thereby improving the performance of the antenna system. Specifically, the antenna configuration in this embodiment can be as follows:

[0302] In portrait mode, the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the seventh antenna ANT7 of the bezel antenna group can be selected as the target communication antenna. In portrait mode, the lower half of the electronic device is usually held with one or both hands. Therefore, the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the seventh antenna ANT7 located in the upper half of the bezel have high radiation efficiency. Antenna switching can be achieved through an antenna switching switch.

[0303] In landscape mode, with the top bezel 11-5 positioned to the left, it can be used with one or both hands. Similar to the hand grip shown in Figure 8C, when gripped with both hands or only the left hand, the first antenna ANT1 is easily held, while the seventh antenna ANT7 may be held by the index finger in some grip positions. Therefore, the second antenna ANT2, the third antenna ANT3, the eighth antenna ANT8, and the first sub-antenna ANT6-1 (or the second sub-antenna ANT6-2) can be directly selected as the four target communication antennas. Since the seventh antenna ANT7 may not be held by the index finger in some cases, only the second antenna ANT2, the third antenna ANT3, and the eighth antenna ANT8 can be selected, and the antenna control method in subsequent embodiments can be used to switch or tune between ANT6-2, ANT6-1, and ANT7.

[0304] In landscape mode, with the top bezel 11-5 positioned to the right, it can be used with one or both hands. Similar to the hand grip shown in Figure 8D, when held with both hands or only the right hand, the seventh antenna ANT7 is easily held, while the first antenna ANT1 may be held by the index finger in some grip positions. Therefore, the second antenna ANT2, the third antenna ANT3, the eighth antenna ANT8, and the first sub-antenna ANT6-1 (or the second sub-antenna ANT6-2) can be directly selected as the four target communication antennas. Since the first antenna ANT1 may not be held by the index finger in some cases, only the second antenna ANT2, the third antenna ANT3, and the eighth antenna ANT8 can be selected, and the antenna control methods in subsequent embodiments can be used to switch or tune between ANT6-2, ANT6-1, and ANT7.

[0305] It should be noted that the possible ways in which an electronic device can be held cannot be exhaustively listed in this embodiment. However, the antenna layout of the antenna system in this embodiment can avoid the user's hand grip in most usage scenarios, ensuring that at least four antennas are not held simultaneously.

[0306] Therefore, it can be seen that the antenna system of this embodiment can ensure that at least four antennas are not simultaneously blocked (or held) in most usage scenarios, whether in portrait or landscape mode. This improves the overall communication performance of the electronic device in various scenarios, resulting in a better user experience.

[0307] Figures 10D to 10F show a rear view of an electronic device 10, providing an antenna system for the electronic device 10. In one embodiment, the antenna system serves a frequency band of 2GHz-10GHz. For example, the antenna system serves a high-frequency band (e.g., 3000MHz to 6000MHz) of a cellular network Sub-6G. The antenna system includes: a first frame antenna group, a first rear cover antenna group, and an antenna control device (not shown). The first frame antenna group is disposed on a frame 11, and the first rear cover antenna group is disposed on a rear cover 12. The antenna control device is connected to the antennas in the first frame antenna group and the first rear cover antenna group.

[0308] The first frame antenna group includes: a first antenna, a second antenna, a third antenna, a seventh antenna, and an eighth antenna. Based on the previous ten embodiments, the first frame antenna group adds an eighth antenna, which is represented by ANT1, ANT2, ANT3, ANT7, and ANT8 in the accompanying drawings.

[0309] The first rear cover antenna group may include the layout of the first rear cover antenna group in the foregoing embodiments. In one embodiment, the first rear cover antenna group may also have the following layout:

[0310] As shown in FIGS. 10D to 10F, in one embodiment, the first rear cover antenna group includes: the fourth antenna and / or the fifth antenna. In the drawings, the fourth antenna is represented by ANT4 for the corresponding antenna, and the fifth antenna is represented by ANT5 for the corresponding antenna.

[0311] Among them, the first antenna ANT1 can be located at a position closer to the second side frame 11-3 relative to the first side frame 11-1; the seventh antenna ANT7 can be located at a position closer to the first side frame 11-1 relative to the second side frame 11-3; the eighth antenna ANT8 is located in the middle of the first side frame 11-1; the second antenna ANT2 and the third antenna ANT3 are respectively located in the upper half of the second side frame 11-3 and the first side frame 11-1; where the upper half refers to the half of the second side frame 11-3 and the first side frame 11-1 close to the top frame 11-5; the middle of the first side frame 11-1 can be understood as the distance range formed by extending 20 mm in the directions of the top frame 11-5 and the bottom frame 11-7 respectively along the perpendicular bisector of the first side frame 11-1, and the feeding point of the eighth antenna ANT8 can be located within this distance range.

[0312] The minimum distance value between the radiator of the fourth antenna ANT4 and the top frame 11-5 is D1, and the minimum distance value between the radiator of the fourth antenna ANT4 and the first side frame 11-1 is D4; the minimum distance value between the radiator of the fifth antenna ANT5 and the top frame 11-5 is D3, and the minimum distance value between the radiator of the fifth antenna ANT5 and the second side frame 11-3 is D2; where 0 < D1 < 25 mm, 0 < D2 < a, 0 < D3 < 25 mm, 0 < D4 < a, and a is half of the length value of the top frame 11-5 or the bottom frame 11-7.

[0313] In this embodiment, the setting of 6 or 7 antennas can achieve that in most scenarios of horizontal and vertical screens, at least four antennas can be ensured not to be held simultaneously. Therefore, 4 antennas with better signal quality can be selected for cellular network communication, thereby improving the performance of the antenna system. Specifically, the configuration of the antennas in this embodiment can be as follows:

[0314] In the vertical screen usage scenario, the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the seventh antenna ANT7 of the frame antenna group can be selected as the target communication antennas. In the vertical screen usage scenario, generally, the lower half of the electronic device is held with one hand or both hands. Therefore, the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the seventh antenna ANT7 located in the upper half of the frame have high radiation efficiency, and the switching of the antennas can be achieved through an antenna switching switch.

[0315] In landscape mode, the top bezel 11-5 is located on the left, allowing for one-handed or two-handed use in landscape mode. Similar to the hand-holding situation shown in Figure 8C, when holding with both hands or only the left hand, as shown in Figure 10D, if the rear cover antenna group only includes the fifth antenna ANT5, then the first antenna ANT1 and the fifth antenna ANT5 can be easily held, and the second antenna ANT2, the third antenna ANT3, the eighth antenna ANT8, and the seventh antenna ANT7 can be directly selected as the four target communication antennas to work; as shown in Figure 10E, if the rear cover antenna group only includes the fourth antenna ANT4, then the first antenna ANT1 can be easily held. Since the seventh antenna ANT7 and the fourth antenna ANT4 may also be held, the fourth antenna ANT4 and the seventh antenna ANT7 can be switched or tuned through the antenna control method of the subsequent embodiment to determine one of them; as shown in Figure 10F, if the rear cover antenna group includes the fourth antenna ANT4 and the fifth antenna ANT5, then the first antenna ANT1 and the fifth antenna ANT5 can be easily held. Since the seventh antenna ANT7 and the fourth antenna ANT4 may also be held, the fourth antenna ANT4 and the seventh antenna ANT7 can be switched or tuned through the antenna control method of the subsequent embodiment to determine one of them.

[0316] In landscape mode, with the top bezel 11-5 positioned on the right, it can be used with one or both hands in landscape mode. Similar to the hand grip shown in Figure 8D, when gripped with both hands or only with the right hand, as shown in Figure 10E, if the rear cover antenna group only includes the fourth antenna ANT4, then the fourth antenna ANT4 and the seventh antenna ANT7 can be easily gripped. The first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the eighth antenna ANT8 can be directly selected as the four target communication antennas. As shown in Figure 10D, if the rear cover antenna group only includes the fifth antenna ANT5, then the seventh antenna ANT7 can be easily gripped. Since the first antenna ANT1 and the fifth antenna ANT5 may also be gripped, the antenna control method in the subsequent embodiment can be used to switch or tune the first antenna ANT1 and the fifth antenna ANT5 to determine one of them. As shown in Figure 10F, if the rear cover antenna group includes the fourth antenna ANT4 and the fifth antenna ANT5, then the fourth antenna ANT4 and the seventh antenna ANT7 can be easily gripped. Since the first antenna ANT1 and the fifth antenna ANT5 may also be gripped, the antenna control method in the subsequent embodiment can be used to switch or tune the first antenna ANT1 and the fifth antenna ANT5 to determine one of them.

[0317] It should be noted that the possible ways in which an electronic device can be held cannot be exhaustively listed in this embodiment. However, the antenna layout of the antenna system in this embodiment can avoid the user's hand grip in most usage scenarios, ensuring that at least four antennas are not held simultaneously.

[0318] Therefore, it can be seen that the antenna system in this embodiment can ensure that at least four antennas are not simultaneously blocked (or held) in most usage scenarios, whether in portrait or landscape mode. This improves the overall communication performance of the electronic device in various scenarios, resulting in a better user experience.

[0319] Based on the aforementioned embodiments, the first frame antenna group further includes a ninth antenna, denoted as ANT9 in the accompanying drawings. ANT9 is located in the middle of the second side frame 11-3, and the positions of the remaining antennas can be referenced in the aforementioned embodiments.

[0320] As shown in Figure 10G, which illustrates the layout of an antenna system in this embodiment, the first rear cover antenna group includes a fourth antenna and a fifth antenna. In the figure, the fourth antenna is represented by ANT4 and the fifth antenna by ANT5.

[0321] In the antenna layout shown in Figure 10G:

[0322] In portrait mode usage scenarios, the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the seventh antenna ANT7 of the bezel antenna group can be selected as the target communication antennas. In portrait mode usage, the lower half of the electronic device is typically held with one or both hands; therefore, the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the seventh antenna ANT7, located in the upper half of the bezel, have high radiation efficiency. In some special cases, the second antenna ANT2 and the third antenna ANT3 may also be held; therefore, depending on the antenna control method in subsequent embodiments, it may be necessary to replace the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the seventh antenna ANT7 with the eighth antenna ANT8 and the ninth antenna ANT9. Antenna switching can be achieved through an antenna switching switch.

[0323] In landscape mode, the top bezel 11-5 is located on the left, allowing for one-handed or two-handed use. Similar to the hand grip shown in Figure 8C, when gripped with both hands or only the left hand, the first antenna ANT1 and the fifth antenna ANT5 are easily gripped. In some scenarios, the seventh antenna ANT7 and the fourth antenna ANT4 may also be gripped. Therefore, the second antenna ANT2, the third antenna ANT3, the eighth antenna ANT8, and the ninth antenna ANT9 can be directly selected as the four target communication antennas.

[0324] In landscape mode, with the top bezel 11-5 positioned to the right, it can be used with one or both hands. Similar to the hand grip shown in Figure 8D, when gripped with both hands or only the right hand, the seventh antenna ANT7 and the fourth antenna ANT4 are easily gripped. In some scenarios, the first antenna ANT1 and the fifth antenna ANT5 may also be gripped. Therefore, the second antenna ANT2, the third antenna ANT3, the eighth antenna ANT8, and the ninth antenna ANT9 can be directly selected as the four target communication antennas.

[0325] It should be noted that accidental power button presses can negatively impact the gaming or multimedia experience. Therefore, when playing games or watching videos in landscape mode, it's common practice to place the power button, typically located on the first side bezel (11-1) or the second side bezel (11-3), at the top to prevent accidental presses. This factor should also be considered when designing antenna layouts. For example, if the power button is located on the first side bezel (11-1), the priority for the eighth antenna (ANT8) is higher than that for the ninth antenna (ANT9), because the eighth antenna (ANT8) is more likely to be placed at the top during landscape gaming or multimedia operations.

[0326] Similarly, considering the left and right hands used for making calls, since the proportion of calls made with the right hand is generally higher than with the left hand, the fifth antenna ANT5 has a higher priority than the fourth antenna ANT4. This is because when making calls with the right hand, the fifth antenna ANT5 is relatively far from the head, resulting in less radiation to the head and a smaller decrease in radiation efficiency; the situation is similar when using the left hand.

[0327] As shown in Figure 10H, which illustrates another antenna system layout in this embodiment, the first rear cover antenna group includes a sixth antenna. In one embodiment, the sixth antenna includes a first sub-antenna ANT6-1 and a second sub-antenna ANT6-2.

[0328] In the antenna layout shown in Figure 10H:

[0329] In portrait mode usage scenarios, the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the seventh antenna ANT7 of the bezel antenna group can be selected as the target communication antennas. In portrait mode usage, the lower half of the electronic device is typically held with one or both hands; therefore, the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the seventh antenna ANT7, located in the upper half of the bezel, have high radiation efficiency. In some special cases, the second antenna ANT2 and the third antenna ANT3 may also be held; therefore, depending on the antenna control method in subsequent embodiments, it may be necessary to replace the first antenna ANT1, the second antenna ANT2, the third antenna ANT3, and the seventh antenna ANT7 with the eighth antenna ANT8 and the ninth antenna ANT9. Antenna switching can be achieved through an antenna switching switch.

[0330] In landscape mode, the top bezel 11-5 is located on the left, allowing for single-handed or double-handed use. Similar to the hand grip shown in Figure 8C, when held with both hands or only the left hand, the first antenna ANT1 is easily gripped, and in some scenarios, the seventh antenna ANT7 may also be gripped. Therefore, the second antenna ANT2, the third antenna ANT3, the eighth antenna ANT8, and the ninth antenna ANT9 can be directly selected as the four target communication antennas. If the second antenna ANT2, the third antenna ANT3, the eighth antenna ANT8, or the ninth antenna ANT9 is gripped, tuning can be performed according to the antenna control method in subsequent embodiments, or switching to the first sub-antenna ANT6-1 and the second sub-antenna ANT6-2.

[0331] In landscape mode, with the top bezel 11-5 positioned to the right, it can be used with one or both hands. Similar to the hand grip shown in Figure 8D, the seventh antenna ANT7 is easily held when gripped with both hands or only the right hand. In some scenarios, the first antenna ANT1 may also be held. Therefore, the second antenna ANT2, the third antenna ANT3, the eighth antenna ANT8, and the ninth antenna ANT9 can be directly selected as the four target communication antennas. If the second antenna ANT2, the third antenna ANT3, the eighth antenna ANT8, or the ninth antenna ANT9 is held, tuning can be performed according to the antenna control method in subsequent embodiments, or the first sub-antenna ANT6-1 and the second sub-antenna ANT6-2 can be switched.

[0332] It should be noted that the possible ways in which an electronic device can be held cannot be exhaustively listed in this embodiment. However, the antenna layout of the antenna system in this embodiment can avoid the user's hand grip in most usage scenarios, ensuring that at least four antennas are not held simultaneously.

[0333] Therefore, it can be seen that the antenna system in this embodiment can ensure that at least four antennas are not simultaneously blocked (or held) in most usage scenarios, whether in portrait or landscape mode. This improves the overall communication performance of the electronic device in various scenarios, resulting in a better user experience.

[0334] It should be noted that in the antenna system of the aforementioned embodiment, the first sub-antenna ANT6-1 is closer to the second side frame 11-3 relative to the first side frame 11-1, and the second sub-antenna is closer to the first side frame 11-1 relative to the second side frame 11-3; the fourth antenna ANT4 and the fifth antenna ANT5 are closer to the top frame 11-5 relative to the sixth antenna.

[0335] Figure 11A shows a rear view of an electronic device 10. An embodiment of this application provides an antenna system for the electronic device 10. In one embodiment, the antenna system serves a frequency band of 2GHz-10GHz. For example, the antenna system serves a certain frequency band of a WIFI network (e.g., WIFI 5G, WIFI 2.4G). The antenna system includes: a second frame antenna group, a second rear cover antenna group, and an antenna control device (not shown). The second frame antenna group is disposed on the frame 11, and the second rear cover antenna group is disposed on the rear cover 12. The antenna control device is connected to the antennas in the second frame antenna group and the second rear cover antenna group.

[0336] The second frame antenna group includes: a first communication antenna and a second communication antenna, and the second rear cover antenna group includes: a third communication antenna. In the attached drawings, the corresponding antennas are represented by WIFIC0, WIFIC1 and WIFIC0TAS, respectively.

[0337] The first communication antenna WIFIC0 can be located in the middle of the top frame 11-5 or near the first side frame 11-1 relative to the second side frame 11-3; the second communication antenna WIFIC1 is located on the upper half of the first side frame 11-1, where the upper half refers to the half of the second side frame 11-3 and the first side frame 11-1 near the top frame 11-5; the third communication antenna WIFIC0TAS is near the first side frame 11-1 relative to the second side frame 11-3, and the minimum distance between the radiator of the third communication antenna WIFIC0TAS and the first side frame is at least 3mm, and the minimum distance between the radiator of the third communication antenna and the top frame is at least 20mm.

[0338] In this embodiment, the three-antenna configuration ensures that at least two antennas are not simultaneously held in most scenarios involving both portrait and landscape screens. Therefore, the two antennas with better signal quality can be selected for Wi-Fi network communication, thereby improving the performance of the antenna system. Specifically, the configuration of the three antennas in this embodiment is as follows:

[0339] In portrait mode, you can select either the first communication antenna (WIFI C0) or the second communication antenna (WIFI C1) on the bezel antenna array. In portrait mode, the lower half of the electronic device is typically held with one or both hands; therefore, the first and second communication antennas (WIFI C0 and WIFI C1) located on the upper half of the bezel have high radiation efficiency. Antenna switching can be achieved using an antenna switching switch.

[0340] In landscape mode, referring to the grip shown in Figure 8C, regardless of whether the top bezel 11-5 is in the left or right hand position, whether using the screen with one or both hands, the first communication antenna (WIFI C0) may be held. Therefore, you can directly select the second communication antenna (WIFI C1) and the third communication antenna (WIFI C0 TAS) as the target communication antennas. For example, in a two-handed gaming scenario, you can use the antenna switch to switch from the first communication antenna (WIFI C0) to the third communication antenna (WIFI C0 TAS).

[0341] It should be noted that the possible ways in which an electronic device can be held cannot be exhaustively listed in this embodiment. However, the antenna layout of the antenna system in this embodiment can avoid the user's hand grip in most usage scenarios, ensuring that at least two antennas are not held at the same time.

[0342] Therefore, it can be seen that the antenna system of this embodiment can ensure that at least two antennas are not simultaneously blocked (or held) in most usage scenarios, whether in portrait or landscape mode. This improves the overall communication performance of the electronic device in various scenarios, resulting in a better user experience.

[0343] As an optional embodiment, the first communication antenna WIFIC0 shares an antenna structure (radiator) with the seventh antenna ANT7 in the aforementioned embodiment, WIFIC1 shares an antenna structure with ANT3 in the aforementioned embodiment, and the third communication antenna WIFIC0TAS shares an antenna structure with the second sub-antenna ANT6-2 in the aforementioned embodiment. Specifically, this can be achieved through a parasitic antenna structure. It is understood that sharing antenna structures can save antenna layout space while improving antenna system performance, allowing electronic devices to incorporate more antennas, or facilitating the miniaturization of electronic devices.

[0344] As shown in Figure 11B, based on the aforementioned embodiment, the second frame antenna group further includes a fourth communication antenna, and the second rear cover antenna group further includes a fifth communication antenna. In the accompanying drawings, the corresponding antennas are represented by WIFIC2 and WIFIC2TAS, respectively.

[0345] The fourth communication antenna WIFI C2 can be located in the middle of the top frame 11-5 or near the second side frame 11-3 relative to the first side frame 11-1; the fifth communication antenna WIFI C2 TAS is near the second side frame 11-3 relative to the first side frame 11-1, the minimum distance between the radiator of the fifth communication antenna WIFI C2 TAS and the second side frame 11-3 is at least 3mm, and the minimum distance between the radiator of the fifth communication antenna WIFI C2 TAS and the top frame 11-5 is at least 20mm.

[0346] In this embodiment, the configuration of five antennas ensures that at least two antennas are not simultaneously held in most scenarios involving both portrait and landscape screens. Therefore, the two antennas with better signal quality can be selected for cellular network communication, thereby improving the performance of the antenna system. Specifically, the configuration of the five antennas in this embodiment is as follows:

[0347] In portrait mode, you can select either the first communication antenna (WIFI C0) or the fourth communication antenna (WIFI C2) in the bezel antenna array. In portrait mode, the lower half of the electronic device is typically held with one or both hands; therefore, the first and fourth communication antennas (WIFI C0 and WIFI C2) located at the top of the bezel have high radiation efficiency. Antenna switching can be achieved using an antenna switching switch.

[0348] In landscape mode, referring to the grip shown in Figure 8C, regardless of whether the top bezel 11-5 is in the left or right hand position, it can be used with one or both hands. The first communication antenna (WIFI C0) and the fourth communication antenna (WIFI C2) may be held. Therefore, the antenna control method in subsequent embodiments can be used to switch or tune the second communication antenna (WIFI C1), the fifth communication antenna (WIFI C2 TAS), and the third communication antenna (WIFI C0 TAS), selecting the two with better signal quality as the target communication antennas. This is exemplified in two-handed gaming scenarios.

[0349] It should be noted that the possible ways in which an electronic device can be held cannot be exhaustively listed in this embodiment. However, the antenna layout of the antenna system in this embodiment can avoid the user's hand grip in most usage scenarios, ensuring that at least two antennas are not held at the same time.

[0350] Therefore, it can be seen that the antenna system of this embodiment can ensure that at least two antennas are not simultaneously blocked (or held) in most usage scenarios, whether in portrait or landscape mode. This improves the overall communication performance of the electronic device in various scenarios, resulting in a better user experience.

[0351] As an optional embodiment, the fourth communication antenna WIFIC2 shares an antenna structure (radiator) with the first antenna ANT1 in the aforementioned embodiment, and the fifth communication antenna WIFI C2 TAS shares an antenna structure (radiator) with the first sub-antenna ANT6-1 in the aforementioned embodiment. Specifically, this can be achieved through a parasitic antenna structure. It is understood that sharing antenna structures can save antenna layout space while improving antenna system performance, allowing electronic devices to incorporate more antennas, or facilitating the miniaturization of electronic devices.

[0352] The foldable screen electronic device shown in Figures 3A-3E is also referred to as a foldable electronic device in this embodiment. The foldable electronic device includes a first body and a second body, which are hinged together to form the foldable electronic device. Both the first and second body housings have a frame and a back cover. The first body is the body housing screen A in the figures, and the second body is the body housing screen B in the figures. The surfaces containing screens A and B are the front. The frames and back covers of the first and second body housings are similar to those in the aforementioned embodiments, and their specific structures will not be described again here.

[0353] The foldable electronic device may include the antenna system for cellular networks described in the previous embodiments, or the antenna system for WIFI networks described in the previous embodiments, or both antenna systems may be included simultaneously.

[0354] In this embodiment, the antenna system for the cellular network is referred to as the first antenna system, and the antenna system for the WIFI network is referred to as the second antenna system. The first antenna system includes: a first frame antenna group, a first rear cover antenna group, and an antenna control device; the second antenna system includes: a second frame antenna group, a second rear cover antenna group, and an antenna control device.

[0355] Considering that user habits make it more likely that the second body will be held, the first antenna system and the second antenna system can be deployed on the first body simultaneously, thereby improving antenna communication performance.

[0356] As shown in Figure 12A, Figure 12A is a schematic diagram of the antenna layout of a foldable electronic device. Figure 12A is a rear view of the foldable electronic device. The frame 111 of the first body in the figure has a top frame 11-5-1, a bottom frame 11-7-1, a first side frame 11-1, and a hinged side frame 11-2. The antenna group of the first frame includes a third antenna, a seventh antenna, an eighth antenna, a tenth antenna, and an eleventh antenna. The antenna group of the first rear cover includes a fifth antenna, which are represented by ANT3, ANT7, ANT8, ANT10, ANT11, and ANT5, respectively.

[0357] Among them, the seventh antenna ANT7 is located on the top frame 11-5-1 and close to the first side frame 11-1. The third antenna ANT3, the eighth antenna ANT8, and the tenth antenna ANT10 are located on the first side frame 11-1. The eleventh antenna ANT11 is located on the bottom frame 11-7-1 of the first fuselage body. The third antenna ANT3 and the tenth antenna ANT10 are both located in the upper half of the first fuselage body near the top. The eighth antenna ANT8 is located in the middle of the first side frame 11-1.

[0358] The fifth antenna ANT5 is closer to the hinged side frame 11-2 than the first side frame 11-1. The minimum distance value between the radiator of the fifth antenna ANT5 and the top frame 11-5-1 of the first body is D3, and the minimum distance value from the first side frame 11-1 is D2. Where 0 < D2 < a, 0 < D3 < 25 mm, and a is half of the length value of the top frame 11-5-1 or the bottom frame 11-7-1 of the first body.

[0359] In the case of this 6-antenna layout, it is possible to ensure that at least four antennas are not simultaneously held in most scenarios of portrait and landscape screens. Therefore, four antennas with relatively better signal quality can be selected for cellular network communication, thereby improving the performance of the antenna system. Specifically, the configuration of the 6 antennas in this embodiment can be as follows:

[0360] In the portrait screen usage scenario, the tenth antenna ANT10, the seventh antenna ANT7, and the third antenna ANT3 of the frame antenna group can be selected. Then, according to the antenna control method of the subsequent embodiment, the antenna control device is used to switch or tune the fifth antenna ANT5 and the eighth antenna ANT8 to select one of them. In the portrait screen usage scenario, generally, the lower part of the electronic device is held with one hand or both hands. Therefore, the tenth antenna ANT10, the seventh antenna ANT7, and the third antenna ANT3 located on the upper part of the frame have high radiation efficiency. The eighth antenna ANT8 is in the middle position and may be held. Since the fifth antenna ANT5 is an antenna on the upper part of the rear cover, considering radiation efficiency and antenna directivity, the performance of the antenna receiving direction aligned with the incoming wave direction of the base station is better. Therefore, in specific scenarios, it can be switched or tuned through the antenna control method of the subsequent embodiment for selection.

[0361] In the landscape screen usage scenario, and when the top frame 11-5 is on the right hand side, it can be used in landscape screen with one hand or both hands. The seventh antenna ANT7 is easily held, and the tenth antenna ANT10 and the eleventh antenna ANT11 may be held. Therefore, the eighth antenna ANT8, the third antenna ANT3, and the fifth antenna ANT5 can be selected. Then, according to the antenna control method of the subsequent embodiment, the antenna control device is used to switch or tune to select the tenth antenna ANT10 or the eleventh antenna ANT11 as the target communication antenna.

[0362] In the landscape usage scenario, when the top border 11-5 is on the left-hand side, it can be used in a single-handed or two-handed landscape mode. The fifth antenna ANT5 is easily grasped, and it is also possible to grasp the seventh antenna ANT7 and the eleventh antenna ANT11. Therefore, the eighth antenna ANT8, the third antenna ANT3, and the tenth antenna ANT10 can be selected, and then, according to the antenna control method of the subsequent embodiments, the antenna control device can be used to switch or tune to select the seventh antenna ANT7 or the eleventh antenna ANT11 as the target communication antenna.

[0363] Furthermore, as shown in FIG. 12B, FIG. 12B is a schematic diagram of the antenna layout of another folding electronic device, and FIG. 12B is a rear view of the folding electronic device. In the case of the antenna layout shown in FIG. 12A, the first rear cover antenna group further includes a fourth antenna and a second sub-antenna, and the corresponding antennas are represented by ANT4 and ANT6-2 in the drawings.

[0364] Among them, the fourth antenna ANT4 is closer to the first side border 11-1 relative to the hinge side border 11-2. The minimum distance value between the radiator of the fourth antenna ANT4 and the top border 11-5-1 of the first body is D3, and the minimum distance value between the radiator of the fourth antenna ANT4 and the first side border 11-1 is D4; the minimum distance value between the radiator of the second sub-antenna ANT6-2 and the first side border 11-1 is at least 3 mm, and the minimum distance value between the radiator of the second sub-antenna ANT6-2 and the top border 11-5-1 of the first body is at least 20 mm;

[0365] Among them, 0 < D1 < 25 mm, 0 < D3 < 25 mm, 0 < D4 < a, where a is half of the length value of the top border or the bottom border of the first body.

[0366] In the case of this 8-antenna layout, it is possible to ensure that at least four antennas are not simultaneously grasped in most scenarios of portrait and landscape modes. Therefore, four antennas with relatively better signal quality can be selected for cellular network communication, thereby improving the performance of the antenna system. Specifically, the configuration of the 8 antennas in this embodiment can be as follows:

[0367] In portrait mode usage scenarios, the tenth antenna ANT10, the seventh antenna ANT7, and the third line ANT3 of the bezel antenna group can be selected. Then, according to the antenna control method in the subsequent embodiments, the fourth antenna ANT4, the fifth antenna ANT5, the eighth antenna ANT8, and the second sub-antenna ANT6-2 can be selected using the antenna control device. In portrait mode usage scenarios, the lower half of the electronic device is generally held with one or both hands. Therefore, the tenth antenna ANT10, the seventh antenna ANT7, and the third line ANT3, located in the upper half of the bezel, have high radiation efficiency. The eighth antenna ANT8 is located in the middle and may be held. The fourth antenna ANT4, the fifth antenna ANT5, and the second sub-antenna ANT6-2, being antennas near the top of the back cover, need to consider radiation efficiency and antenna directivity. Antennas with their receiving direction aligned with the direction of incoming waves from the base station perform better. Therefore, in specific scenarios, the antennas need to be switched or tuned using the antenna control method in the subsequent embodiments.

[0368] In landscape mode, with the top bezel 11-5-1 positioned to the right, it can be used with one or both hands. The fourth antenna ANT4 and the seventh antenna ANT7 are easily held in the hand, while the tenth antenna ANT10 and the eleventh antenna ANT11 may be difficult to hold. Therefore, the eighth antenna ANT8, the third line ANT3, the fifth antenna ANT5, and the second sub-antenna ANT6-2 can be selected as the target communication antennas.

[0369] In landscape mode, with the top bezel 11-5-1 positioned to the left, it can be used with one or both hands. The fifth antenna, ANT5, is easily held in the hand, as are the seventh, fourth, and eleventh antennas, ANT7, ANT4, and ANT11. Therefore, the eighth antenna, ANT8, the third antenna, ANT3, the tenth antenna, ANT10, and the second sub-antenna, ANT6-2, can be selected as the target communication antennas.

[0370] As an optional embodiment, the antenna implementation of the second antenna system is the same as the three antenna systems for the WIFI network in the aforementioned embodiments. Specifically, the second frame antenna group includes a first communication antenna and a second communication antenna, and the second rear cover antenna group includes a third communication antenna. These are represented in the accompanying drawings as WIFIC0, WIFIC1, and WIFIC0TAS, respectively. The first communication antenna WIFIC0 shares a single antenna structure (radiator) with the seventh antenna ANT7, the second communication antenna WIFIC1 shares a single antenna structure (radiator) with the third antenna ANT3 or the tenth antenna ANT10, and the third communication antenna WIFIC0TAS shares a single antenna structure (radiator) with the second sub-antenna ANT6-2. Specifically, this can be achieved through a parasitic antenna structure. It is understood that sharing antenna structures can improve antenna system performance while saving antenna layout space, allowing electronic devices to accommodate more antennas or facilitating miniaturization.

[0371] It should be noted that the possible ways in which an electronic device can be held cannot be exhaustively listed in this embodiment. However, the antenna layout of the antenna system in this embodiment can avoid the user's hand grip in most usage scenarios, ensuring that at least four cellular antennas or at least two WIFI antennas are not held simultaneously.

[0372] Therefore, it can be seen that the antenna system of this embodiment can ensure that at least four cellular antennas or at least two Wi-Fi antennas are not simultaneously blocked (or held) in most usage scenarios, whether in portrait or landscape mode. This improves the overall communication performance of foldable screen electronic devices in various scenarios, resulting in a better user experience.

[0373] As shown in Figure 12C, Figure 12C is a schematic diagram of the antenna layout of another foldable electronic device. Figure 12A is a rear view of the foldable electronic device. The foldable electronic device in the figure is the same as the aforementioned embodiment. Its first body frame 111 has a top frame 11-5-1, a bottom frame 11-7-1, a first side frame 11-1, and a hinged side frame 11-2. The difference is that the first frame antenna group includes: a first antenna, a third antenna, a seventh antenna, a tenth antenna, and an eleventh antenna. The first rear cover antenna group includes a second sub-antenna, which are respectively represented by ANT1, ANT3, ANT7, ANT10, ANT11, and ANT6-2.

[0374] Among them, ANT1 is located on the top frame 11-5-1 and close to the hinge side frame 11-2 relative to the first side frame 11-1; the seventh antenna ANT7 is located on the top frame 11-5-1 and close to the first side frame 11-1; the third antenna ANT3 and the tenth antenna ANT10 are located on the first side frame 11-1; and the eleventh antenna ANT11 is located on the bottom frame 11-7-1 of the first fuselage body. The third antenna ANT3 and the tenth antenna ANT10 are both located in the upper half of the first fuselage body near the top.

[0375] The second sub-antenna ANT6-2 is close to the first side frame relative to the hinged side frame 11-2. The minimum distance between the radiator of the second sub-antenna ANT6-2 and the first side frame 11-1 is at least 3 mm, and the minimum distance between the radiator of the second sub-antenna ANT6-2 and the top frame 11-5-1 of the first fuselage body is at least 20 mm.

[0376] With this 6-antenna layout, at least four antennas can be kept separate in most scenarios, whether the screen is horizontal or vertical. Therefore, the four antennas with the best signal quality can be selected for cellular network communication, thereby improving the performance of the antenna system. Specifically, the configuration of the 6 antennas in this embodiment is as follows:

[0377] In portrait mode, you can directly select the first antenna ANT1, the third antenna ANT3, the seventh antenna ANT7, and the tenth antenna ANT10 in the bezel antenna group. In portrait mode, the lower half of the electronic device is usually held with one or both hands. Therefore, the first antenna ANT1, the third antenna ANT3, the seventh antenna ANT7, and the tenth antenna ANT10 located in the upper half of the bezel have high radiation efficiency.

[0378] In landscape mode, with the top bezel 11-5-1 positioned to the right, it can be used with one or both hands. The seventh antenna ANT7 is easily held, while the tenth and eleventh antennas ANT10 and ANT11 may also be held. Therefore, the second sub-antenna ANT6-2, the third antenna ANT3, and the first antenna ANT1 can be selected. Then, according to the antenna control method in subsequent embodiments, the antenna control device can be used to switch or tune to select either the tenth antenna ANT10 or the eleventh antenna ANT11 as the target communication antenna.

[0379] In the landscape screen usage scenario, when the top border 11-5-1 is on the left hand side, it can be used in a single-handed or two-handed landscape mode. The first antenna ANT1 is easily grasped, and it is also possible to grasp the seventh antenna ANT7 and the eleventh antenna ANT11. Therefore, the second sub-antenna ANT6-2, the third antenna ANT3, and the tenth antenna ANT10 can be selected, and then, according to the antenna control method of the subsequent embodiments, the antenna control device is used to switch or tune to select the seventh antenna ANT7 or the eleventh antenna ANT11 as the target communication antenna.

[0380] Furthermore, as shown in FIG. 12D, FIG. 12D is a schematic diagram of the antenna layout of another folding electronic device, and FIG. 12B is a rear view of the folding electronic device. In the antenna layout shown in FIG. 12C, the first rear cover antenna group further includes a fourth antenna and a fifth antenna, and the corresponding antennas are represented by ANT4 and ANT5 in the drawings.

[0381] Among them, the fourth antenna ANT4 is closer to the first side border 11-1 relative to the hinge side border 11-2. The minimum distance value between the radiator of the fourth antenna ANT4 and the top border 11-5-1 of the first body is D3, and the minimum distance value between the radiator of the fourth antenna ANT4 and the first side border 11-1 is D4; the fifth antenna ANT5 is closer to the hinge side border 11-2 relative to the first side border 11-1. The minimum distance value between the radiator of the fifth antenna ANT5 and the top border 11-5-1 of the first body is D3, and the minimum distance value between it and the first side border 11-1 is D2; where 0 < D2 < a, 0 < D3 < 25 mm, and a is half of the length value of the top border 11-5-1 or the bottom border 11-7-1 of the first body.

[0382] In this 8-antenna layout scenario, it is possible to ensure that at least four antennas are not simultaneously grasped in most scenarios of portrait and landscape screens. Therefore, 4 antennas with better signal quality can be selected for cellular network communication, thereby improving the performance of the antenna system. Specifically, the configuration of the 8 antennas in this embodiment can be as follows:

[0383] In the portrait screen usage scenario, the first antenna ANT1, the third antenna ANT3, the seventh antenna ANT7, and the tenth antenna ANT10 of the border antenna group can be directly selected. In the portrait screen usage scenario, the electronic device is generally held with one hand or two hands at the lower part. Therefore, the first antenna ANT1, the third antenna ANT3, the seventh antenna ANT7, and the tenth antenna ANT10 located on the upper half of the border have high radiation efficiency.

[0384] In landscape mode, with the top bezel 11-5-1 positioned to the right, it can be used with one or both hands. The fourth antenna ANT4 and the seventh antenna ANT7 are easily held in the hand, while the first antenna ANT1, fifth antenna ANT5, tenth antenna ANT10, and eleventh antenna ANT11 may also be held. Therefore, the second sub-antenna ANT6-2 and the third antenna ANT3 can be selected. Then, according to the antenna control method in subsequent embodiments, the antenna control device can be used to switch or tune to select two of the first antenna ANT1, fifth antenna ANT5, tenth antenna ANT10, and eleventh antenna ANT11 as the target communication antenna.

[0385] In landscape mode, with the top bezel 11-5-1 positioned to the left, it can be used with one or both hands. The first antenna ANT1 and the fifth antenna ANT5 are easily held, as are the fourth antenna ANT4, the seventh antenna ANT7, and the eleventh antenna ANT11. Therefore, the second sub-antenna ANT6-2, the third antenna ANT3, and the tenth antenna ANT10 can be selected. Then, according to the antenna control method in subsequent embodiments, the antenna control device can be used to switch or tune to select one of the fourth antenna ANT4, the seventh antenna ANT7, or the eleventh antenna ANT11 as the target communication antenna.

[0386] It should be noted that the possible ways in which an electronic device can be held cannot be exhaustively listed in this embodiment. However, the antenna layout of the antenna system in this embodiment can avoid the user's hand grip in most usage scenarios, ensuring that at least four antennas are not held simultaneously.

[0387] Therefore, it can be seen that the antenna system of this embodiment can ensure that at least four antennas are not simultaneously blocked (or held) in most usage scenarios, whether in portrait or landscape mode. This improves the overall communication performance of foldable screen electronic devices in various scenarios, resulting in a better user experience.

[0388] In another embodiment, the first antenna system is deployed on the first fuselage body as described in the foregoing embodiment, and the antenna of the second antenna system is deployed on the second fuselage body.

[0389] Specifically, the second frame antenna group includes: a first communication antenna and a second communication antenna, and the second rear cover antenna group includes: a third communication antenna. In the attached drawings, the corresponding antennas are represented by WIFIC0, WIFIC1, and WIFIC0TAS, respectively.

[0390] As shown in Figure 12E, which is a schematic diagram of the antenna layout of another foldable electronic device, the first communication antenna WIFIC0 can be located on the top frame 11-5-2 of the second body and close to the second side frame 11-3 of the second body relative to the hinged side frame 11-2; the second communication antenna WIFIC1 is located on the upper half of the second side frame 11-3 of the second body; the third communication antenna WIFIC0TAS is located close to the second side frame 11-3 and the minimum distance between the radiator of the third communication antenna WIFIC0TAS and the second side frame 11-3 is at least 3mm, and the minimum distance between the radiator of the third communication antenna WIFIC0TAS and the top frame 11-5-2 is at least 20mm.

[0391] As shown in Figures 12A to 12E, 12-1 is the back cover of the first fuselage body, 12-2 is the back cover of the second fuselage body, 11-7-2 is the bottom edge of the second fuselage body, and 112 is the edge of the second fuselage body.

[0392] By deploying the first antenna system and the second antenna system on the first body and the second body respectively, the multi-body feature of the foldable screen is fully utilized, and the antennas of different frequency bands can be distributed more reasonably, further improving the overall performance of the electronic device's antenna system.

[0393] It should be noted that the possible ways in which an electronic device can be held cannot be exhaustively listed in this embodiment. However, the antenna layout of the antenna system in this embodiment can avoid the user's hand grip in most usage scenarios, ensuring that at least four cellular antennas or at least two WIFI antennas are not held simultaneously.

[0394] Therefore, it can be seen that the antenna system of this embodiment can ensure that at least four cellular antennas or at least two Wi-Fi antennas are not simultaneously blocked (or held) in most usage scenarios, whether in portrait or landscape mode. This improves the overall communication performance of foldable screen electronic devices in various scenarios, resulting in a better user experience.

[0395] In addition, for other folding screen cases, the tri-fold screen case shown in Figures 3K to 3L can be set up and expanded with reference to the bi-fold screen case, and the layout of multi-fold screens can be referred to; for the vertical folding screen case shown in Figures 3M to 3O, the antenna system layout can be referred to the case of the aforementioned embodiments when it is unfolded, and the hinge point can be appropriately avoided.

[0396] Furthermore, it is understood that the antennas in the antenna system of the above embodiments have relative distances to meet the isolation requirements for adaptability. The minimum distance between the radiator and the frame can be understood as the vertical distance from the edge of the radiator that has the smallest vertical distance from the frame to the frame. The antenna being close to the frame can be understood as the radiator of the antenna being close to the frame.

[0397] The above embodiments illustrate some possible layouts of the antenna system of electronic devices. The embodiments above only use cellular and Wi-Fi as examples. The cellular frequency band, in addition to the Sub-6GHz band mentioned in the embodiments above, can be applied to the entire cellular frequency band, such as the LTE band, sub-3GHz band, etc. Furthermore, in practical applications, the antenna system of this application can also be used for antenna layouts of different frequency bands such as Bluetooth, satellite, satellite, and GPS.

[0398] In practical electronic devices, antenna control devices may include antenna switching switches, tuning devices, and controllers (e.g., processors). These controllers can be located in a modem (modulator-demodulator), an application processor (AP), or a sensor hub. The controller determines antenna configuration and switching strategies, while the antenna switching switch performs antenna switching. An electronic device may include multiple antenna switching switches; based on relative distance, one antenna switching switch can connect multiple relatively close antennas to achieve switching. Furthermore, in this embodiment, antennas with a high probability of switching in the usage scenario can be connected to the same antenna switching switch to facilitate antenna switching.

[0399] In an optional embodiment, after antenna switching, a TAS (Transmit Antenna Switching) switch can also be performed on the transmit and receive antennas to reconfigure the transmit and receive antennas.

[0400] In the foregoing embodiments, there are different antenna configurations and switching situations in different scenarios. The antenna switching method will be described in detail below based on the antenna system of the foregoing embodiments.

[0401] As shown in Figure 13, this application embodiment provides an antenna control method for an electronic device. This antenna control method can be used to control the antennas in the antenna system of the electronic device in the aforementioned embodiment. The electronic device also includes an accelerometer, a gyroscope, and a SAR sensor. The accelerometer is used to generate acceleration sensing data of the electronic device, the gyroscope is used to generate gyroscope sensing data of the electronic device, and the SAR sensor is used to generate SAR data for each antenna; wherein, SAR (Specific Absorption Rate) is used to generate SAR data for each antenna.

[0402] The method includes:

[0403] S20. Acquire the electronic device's service data, acceleration sensor data, gyroscope sensor data, SAR data, and the reflection coefficients of each antenna;

[0404] In practice, business data refers to the data generated by the running programs of electronic devices (e.g., mobile phones), such as data generated by services like games, video playback, music playback, regular calls, and video calls. Business data can be used to identify the functions that the mobile phone is currently using, such as making calls, playing games, and watching movies.

[0405] Accelerometer and gyroscope data can be used to determine the attitude of an electronic device. The attitude of an electronic device can include: stationary on a horizontal plane, portrait orientation, landscape orientation, etc.

[0406] SAR sensors can be placed on the top, side bezels, back cover, and bottom of electronic devices. The acquired SAR data can be used to detect the proximity of the top, sides, back cover, and bottom of the electronic device to a human body. In other words, by using SAR sensors distributed on the top, sides, back cover, and bottom, electronic devices can determine whether a user is holding the top, sides, back cover, or bottom.

[0407] The reflection coefficient is data that the antenna itself generates and can be obtained directly. The reflection coefficient can reflect the signal reflection of the antenna, and when combined with other data, it can reflect the antenna's blockage to a certain extent.

[0408] Specifically, the method in this embodiment can be triggered by a business signal, such as starting a game or starting video playback.

[0409] S40. Based on SAR data, service data, acceleration sensor data, gyroscope sensor data and the reflection coefficient of each antenna, determine the usage scenario of the electronic device and the antenna status configuration information corresponding to the usage scenario; wherein, the usage scenario includes the service type running on the electronic device, the screen orientation of the electronic device, and the user's grip on the electronic device, and the antenna status configuration information includes at least the disconnection status of several antennas in the same frequency band.

[0410] In practical implementation, by combining business data, acceleration sensor data, gyroscope sensor data, SAR data, and the reflection coefficients of each antenna, the usage scenarios of electronic devices can be determined. Usage scenarios include the type of business the electronic device is running, the screen orientation (portrait or landscape), and the user's grip on the device.

[0411] For example, as shown in Figures 8C and 8D, business data determines that the phone is running a game; accelerometer and gyroscope data determine that the electronic device is in landscape mode; SAR data indicates that the top, bottom, and back cover of the electronic device are partially held; and the reflection coefficient reflects the signal reflection of the antennas. Since the signal reflection of the first antenna ANT1 and the fifth antenna ANT5 is relatively weak, it is preliminarily determined that the phone is in a landscape mode for two-handed gaming. Furthermore, the landscape / portrait mode can also include the top of the electronic device being in the left-hand or right-hand position.

[0412] Antenna status configuration information can be presented in the form of a mapping table. That is, the electronic device can store mapping tables, with one mapping table for the top of the antenna system in the left-hand position and another for the top of the antenna in the right-hand position. The mapping table can include multiple usage scenario types, each corresponding to antenna status configuration information. The antenna status configuration information includes at least the disconnection status of several antennas in the same frequency band. Specifically, it can include antenna information configured to be directly connected as the target communication antenna in the corresponding scenario (i.e., the directly selected antennas in the aforementioned embodiments). In addition, it can also include antenna information that may be held and configured to require subsequent tuning or switching. It should be noted that, based on the previously introduced service data, acceleration sensor data, gyroscope sensor data, SAR data, and the reflection coefficients of each antenna, the degree of holding of each antenna can be fused to determine which antennas are configured to be directly connected as the target communication antennas, which antennas are configured to be switched, and which antennas are configured to be tuned. Therefore, each usage scenario can correspond to antenna status configuration information. The holding state or degree of holding of the antenna can include: the antenna is not held, the antenna is fully held, and the antenna is loosely held. Full holding means that the gap of the antenna is completely held, and loose holding means that the gap of the antenna is not completely held.

[0413] Specifically, the mapping table can be pre-set in the electronic device, and the antenna status configuration information can also be determined using artificial intelligence models based on historical or test-obtained service data, acceleration sensor data, gyroscope sensor data, SAR data, and the reflection coefficient of each antenna corresponding to the usage scenario.

[0414] As an optional embodiment, the electronic device also has a touch sensor for generating touch data of the electronic device; the touch sensor may be a TP (Touch Panel) sensor, which can be deployed on the screen, bezel, and back cover of the electronic device to improve the accuracy of left and right hand grip recognition and achieve millimeter-level precise hand grip recognition.

[0415] Accordingly, based on SAR data, service data, acceleration sensor data, gyroscope sensor data, and the reflection coefficients of each antenna, the usage scenarios of the electronic equipment and the corresponding antenna status configuration information are determined, specifically including:

[0416] Based on touch data, SAR data, service data, acceleration sensor data, gyroscope sensor data, and the reflection coefficients of each antenna, the usage scenarios of the electronic devices and the corresponding antenna status configuration information are determined.

[0417] In practical implementation, touch data, SAR data, service data, acceleration sensor data, gyroscope sensor data, and the reflection coefficients of each antenna can be directly input into a trained artificial intelligence model to determine the usage scenario of the electronic device. Utilizing an artificial intelligence model can improve the efficiency of usage scenario determination.

[0418] In some cases, touch (TP) signals may not be detected. For example, a phone case, especially a thick one, can prevent the detection of touch signals, or there may be no TP signal if the finger is not touching the screen. Therefore, the usage scenario of an electronic device can be determined based on SAR data, service data, acceleration sensor data, gyroscope sensor data, and the reflection coefficients of each antenna. However, fusing touch data can improve the accuracy of usage scenario identification.

[0419] In an optional embodiment, the usage scenario of the electronic device and the antenna status configuration information corresponding to the usage scenario can also be determined through the following steps:

[0420] As shown in Figure 14, the steps include the following:

[0421] S402. Determine the type of service being operated by the electronic equipment based on the service data;

[0422] In practice, business data refers to the data generated by the running programs of electronic devices (e.g., mobile phones), such as data generated by services like games, video playback, music playback, regular calls, and video calls. Business data can be used to identify the functions that the mobile phone is currently using, such as making calls, playing games, and watching movies.

[0423] S404. Determine the screen orientation of the electronic device based on the acceleration sensor data and the gyroscope sensor data.

[0424] In practice, acceleration sensor data and gyroscope sensor data can be used to calculate the attitude of the electronic device. The attitude of the electronic device can include: stationary on a horizontal plane, portrait mode, landscape mode, etc.

[0425] S406. Based on touch data, SAR data, and the reflection coefficient of each antenna, determine the gripping status of each antenna in the electronic device;

[0426] In practice, SAR data can be used to detect the proximity of the top, sides, back cover, and bottom of electronic devices to the human body. Reflectance coefficients reflect the signal reflection of the antenna. Touch data reflects the hand's contact with various parts of the electronic device. Combining these three types of data can determine the antenna's gripping status.

[0427] In an alternative embodiment, the signal strength of the antenna can also be used to jointly determine the holding state of each antenna in the electronic device. For example, the signal strength of the antenna can be compared with the signal strength of the historical sliding window. If the signal strength drops by x dB, and x is greater than 2 dB (RSSI) or 3 dB (RSRP), then the antenna may be held.

[0428] In an alternative embodiment, touch data, SAR data, and the reflection coefficients of each antenna can also be input into a trained artificial intelligence model to obtain the gripping state of each antenna in the electronic device.

[0429] S408. Determine the usage scenario of the electronic device based on the type of service it is running, its landscape or portrait orientation, and the orientation of each antenna.

[0430] In the specific implementation process, after determining the type of business the device is operating in, the horizontal and vertical screen status, and the holding status of each antenna, the usage scenario can be directly determined.

[0431] In some alternative embodiments, when determining the use case, the case of a foldable screen can also be considered. Specifically, a Hall sensor can be set in the electronic device to detect the folded and unfolded states.

[0432] S410. Determine the antenna status configuration information corresponding to the usage scenario.

[0433] In the specific implementation process, the antenna status configuration information corresponding to the usage scenario can be determined according to the correspondence between the usage scenario and the antenna status configuration information in the preset mapping table.

[0434] S60. Based on the antenna status configuration information, control some of the antennas among several antennas to switch.

[0435] In the specific implementation process, since the antenna status configuration information already includes the disconnection status information of each antenna, the antennas that need to be updated in the disconnection status can be switched directly by the controller based on the antenna status configuration information, thereby completing the optimal antenna configuration in this scenario and achieving the working state of at least four cellular antennas or at least two WIFI antennas in the aforementioned embodiment.

[0436] Furthermore, when the antenna status configuration information also includes information on antennas that may be held and configured to require subsequent tuning or switching, then it is also necessary to use controllers to control some antennas for tuning or switching. No control measures are taken for antennas that are not held.

[0437] Therefore, in steps S20 to S60, by fusing service data, acceleration sensor data, gyroscope sensor data, SAR data, and the reflection coefficients of each antenna, the usage scenario is determined. Faced with complex and ever-changing user habits, the usage scenario and its corresponding antenna status configuration information can be determined more accurately. This enables efficient identification under different usage scenarios and efficient implementation of at least four cellular antennas or at least two Wi-Fi antennas, thereby improving the overall performance of the electronic device's antenna system and enhancing the user experience of the electronic device in various scenarios.

[0438] Furthermore, since the antenna status configuration information includes at least the disconnection status of several antennas in the same frequency band, it can specifically include antenna information that is configured to be directly connected as the target communication antenna in the corresponding scenario (i.e., the antenna directly selected in the aforementioned embodiment). In addition, it can also include antenna information that may be held and configured to require subsequent tuning or switching. Therefore, in the face of a multi-antenna system with an increased number of antennas, by directly determining the antennas configured to be directly connected as the target communication antenna (i.e., antennas that are not easily held) by using the scenario, the scheduling efficiency can be significantly improved.

[0439] As an optional embodiment, controlling the switching of some antennas among the plurality of antennas according to the antenna state configuration information includes:

[0440] Based on the antenna status configuration information and the signal strength of several antennas, control some of the antennas to switch.

[0441] In practical implementation, for cellular antennas, signal strength can be characterized by RSRP (Reference Signal Receiving Power); for WIFI antennas, signal strength can be characterized by RSSI (Received Signal Strength Indication).

[0442] Specifically, when the antenna status configuration information also includes information about antennas that may be held and configured to require subsequent tuning or switching, if the degree of holding of the antenna is virtual holding, then the antenna is intelligently tuned, such as impedance tuning or aperture tuning; if the degree of holding of the antenna is full holding, then the signal strength of the antenna can be compared with that of the antenna to be switched, thereby assisting in the decision on whether switching is necessary.

[0443] Specifically, the following formula can be used to assist in deciding whether to compare and switch between the current antenna and the antenna to be switched:

[0444] RSRP_ANTa - RSRP_ANTb > x dB, x ≥ 0, for example, x = 1. RSRP_ANTa is the RSRP of the antenna to be switched, and RSRP_ANTb is the RSRP of the fully held antenna. Then the antenna is switched. The same logic applies to WIFI antennas, which will not be elaborated here.

[0445] For example, as shown in Figure 15, which is a schematic diagram of the connection relationship of the antenna system shown in Figure 10G. In the figure, RFIC (Radio Frequency Integrated Circuit) is a radio frequency integrated circuit; FEM (Front-End Modules) is a radio frequency front-end module, and the FEM includes an antenna switching switch. It can be understood that switching can be performed directly using the antenna switching switch within the radio frequency front-end module, eliminating the need for an external antenna switching switch and avoiding increased insertion loss. Both the FEM and the radio frequency integrated circuit can be included in the antenna control device.

[0446] In the diagram, antennas ANT1, ANT2, ANT5, and ANT8 share a single FEM and can switch between each other; antennas ANT3, ANT4, ANT7, and ANT9 also share a single FEM and can switch between each other. The controller generates switching decision commands based on the sweetheart status configuration information and RSRP decisions.

[0447] For example, if we consider the 8 antennas shown in Figure 10G, assuming the phone is used in portrait mode with antennas ANT1, ANT2, ANT3, and ANT7 in the horizontal position, after detecting a two-handed game with the top bezel (11-5) on the left, antenna ANT1 is fully held. In this scenario, antenna ANT8 is located at the top and is a bezel antenna, and it can be switched with antenna ANT1. Therefore, we can directly decide to switch antenna ANT1 to antenna ANT8. Similarly, we can determine the antenna configuration for this scenario as using antennas ANT2, ANT3, ANT8, and ANT9. Based on this, we can determine that RSRP_ANT8 - RSRP_ANT1 > 0dB using the aforementioned RSRP comparison method for auxiliary decision-making. After confirming the auxiliary decision, we can control the switching of antenna ANT1 to antenna ANT8. The situation is similar for other types of antennas (WIFI, Bluetooth, GPS, etc.), and will not be elaborated here.

[0448] In this embodiment, when the antenna is fully secured, a comprehensive decision is made using both scene recognition and signal strength, enabling switching at a low threshold. In some antenna control methods, to avoid frequent invalid switching, the threshold is set relatively high, for example, 3-6 dB; switching will not occur if the threshold is less than 3 dB. However, in this embodiment, the threshold value can be 0 dB. Because scene recognition is incorporated into this switching method, it ensures that switching is only necessary, avoiding invalid switching. Therefore, switching can be completed at a low threshold, significantly improving both the efficiency and accuracy of antenna switching.

[0449] As an optional embodiment, before determining the usage scenario of the electronic device and the corresponding antenna status configuration information based on SAR data, service data, acceleration sensor data, gyroscope sensor data, and the reflection coefficients of each antenna, the method further includes:

[0450] Based on business data and the signal strength of each antenna in the electronic device, determine whether the scene recognition triggering conditions are met;

[0451] If the scene recognition trigger condition is met, the following steps are executed: determining the usage scenario of the electronic device and the corresponding antenna status configuration information based on SAR data, service data, acceleration sensor data, gyroscope sensor data, and the reflection coefficient of each antenna.

[0452] In practical implementation, scene recognition trigger conditions refer to the conditions that initiate subsequent user scene determination methods. Specifically, business data reflects the current operational business of the electronic device. In some business scenarios where antenna signal strength is not required or is not critical, whether the antenna is blocked or not will not affect the user experience, and therefore subsequent scene recognition can be omitted. For example, if running offline video or a single-player game, there is no requirement for antenna signal strength. Although some antenna signals may be weak or the device may be held, subsequent steps are unnecessary. This saves the resources of the electronic device.

[0453] Of course, when the scene is identified as an online video or online game scene, which requires high antenna performance, the scene recognition trigger condition is met, and subsequent steps are executed.

[0454] As an optional embodiment, after controlling some of the antennas among the antennas to switch based on the antenna status configuration information and the acquired signal strength of the antennas, the method further includes:

[0455] After a preset time interval, the signal strength of each antenna of the electronic device is reacquired. If the re-identified signal strength is abnormal, the process returns to the step of controlling some of the antennas to switch based on the antenna status configuration information and the acquired signal strength of several antennas. Alternatively, the process returns to the step of acquiring the electronic device's service data, acceleration sensor data, gyroscope sensor data, SAR data, and the reflection coefficient of each antenna.

[0456] In practice, a preset time interval can be set, for example, 5 seconds. An abnormal signal strength can mean that the signal from the target communication antenna is still weak, or that the signals from other antennas that should be functioning normally are weakening. When the signal strength is abnormal, it indicates that the previous decision was incorrect, or that the usage scenario has changed. On one hand, the process can directly return to the step of controlling the switching of some antennas based on the antenna status configuration information and the obtained signal strength of several antennas, and then switch again according to the usage scenario and signal strength. On the other hand, if the usage scenario has changed, the process can also return to the step of obtaining the electronic device's service data, acceleration sensor data, gyroscope sensor data, SAR data, and the reflection coefficients of each antenna, and re-execute the method steps of the aforementioned embodiment. This forms a feedback mechanism, improves the overall performance of the antenna system, and further enhances the user experience.

[0457] Furthermore, based on the RSRP signal strength, the original maximum power of the channel, and the power backoff due to SAR regulations, a joint determination can be made as to whether switching and / or tuning the antenna improves the overall communication performance of the network. If no improvement is achieved, the aforementioned method steps are executed again. As a feedback mechanism, the user scenario identification and antenna switching strategies are adjusted in a timely manner to improve the accuracy and robustness of the method.

[0458] The following examples will further demonstrate some implementation methods of the antenna control method.

[0459] Figure 16 illustrates an antenna control method based on a cellular network antenna system. The figure shows the following steps executed starting with a service signal trigger:

[0460] Step 1: Calculate the angle using A+G (Accelerometer and gyroscope) sensor data. In one embodiment, if the angle calculation result indicates that the electronic device is in landscape mode, proceed to Step 2; otherwise, the step ends.

[0461] Step 2: When the electronic device is set to landscape mode by the A+G (Accelerometer and gyroscope) sensor data, check the TP signal.

[0462] In one embodiment, if the electronic device is equipped with a phone case, there may be no TP signal due to the thick case, or there may be no TP signal because the finger is not touching the screen, then proceed to Step 3.

[0463] Step 3: When no TP signal is acquired, the holding state (i.e., whether the antenna is being held, and whether it is a full grip or a loose grip) is indicated based on the reflection coefficient and SAR data. In one embodiment, if it is the second holding state (e.g., a full grip), the antenna is switched. In one embodiment, antenna switching can be indicated by reading RSRP data; for example, if RSRP_ANTa - RSRP_ANTb > x dB, the antenna is switched, where x ≥ 0; otherwise, the process ends. In one embodiment, if it is the first holding state (e.g., a loose grip), the antenna is tuned using a smart tuning scheme, for example, to restore the antenna's performance. In one embodiment, if it is the third holding state (e.g., no grip), the process ends. Here, RSRP_ANTa is the RSRP of the antenna to be switched, and RSRP_ANTb is the RSRP of the fully gripped antenna.

[0464] In one embodiment, check the TP signal; if a TP signal is present, proceed to Step 4.

[0465] Step 4: Input the touch data, reflection coefficient and SAR data into the AI ​​model for fusion decision, thereby indicating the holding state (i.e. whether the antenna is being held, and whether it is a full grip or a loose grip).

[0466] In one embodiment, if it is a first gripping state (e.g., a loose grip), the antenna is tuned using a smart tuning scheme, for example, to bring the antenna performance back to normal.

[0467] In one embodiment, if the second gripping state is present (e.g., full grip), the antenna is switched. In one embodiment, antenna switching can be indicated by reading RSRP data; for example, if RSRP_ANTa - RSRP_ANTb > x dB, the antenna is switched, where x ≥ 0; otherwise, the process ends. Here, RSRP_ANTa is the RSRP of the antenna to be switched, and RSRP_ANTb is the RSRP of the fully gripped antenna.

[0468] In one embodiment, the process ends if a third holding state (e.g., no hand holding) is reached.

[0469] In some embodiments, the magnitude of the change in RSRP intensity between hand-held and non-hand-held positions is also used as an input parameter for the fusion decision on whether to hold the antenna slot.

[0470] Finally, antenna switching and / or tuning can be performed based on the antenna configuration corresponding to the usage scenario.

[0471] As shown in Figure 17, an embodiment of this application provides an antenna control method for an electronic device. This antenna control method is used in the antenna system of the electronic device in the foregoing embodiments. The method includes:

[0472] S200: Obtain the service data of the electronic device;

[0473] In the specific implementation process, the business data is the same as in the aforementioned embodiments. The business data may include application information, which is the program currently running on the electronic device, such as games, videos, etc.

[0474] In one optional embodiment, an application whitelist can be set, which includes the applications and their corresponding antennas that require corresponding antenna switching or tuning. For example, the whitelist may include several game information that requires horizontal screen holding with both hands. As long as the application information corresponding to the service data is in the whitelist, antenna switching or tuning can be performed according to preset switching or tuning rules. For example, when the usage scenario of the electronic device shown in Figures 8A and 8C changes, when it is determined that the application information is a game that requires horizontal screen holding with both hands, the radio frequency channel of the first antenna ANT1 running in portrait mode is directly switched to the first sub-antenna ANT6-1.

[0475] Understandably, switching directly based on a whitelist is simple and straightforward. Furthermore, since the application scenarios are generally relatively fixed, this approach can improve antenna system performance to some extent while simplifying the algorithm and reducing costs.

[0476] S400: Based on business data, control at least some antennas in the electronic equipment to switch or tune.

[0477] In practical implementation, since business data can include application information, which reflects the currently running program, and a program can know the user's typical grip posture when running on an electronic device. For example, mobile games require a horizontal, two-handed grip, while WeChat requires a vertical, one-handed or two-handed grip. Therefore, based on the application information, it is possible to determine which antenna needs to be switched or tuned.

[0478] Specifically, based on business data, control at least some antennas in the electronic equipment to switch or tune, including:

[0479] Based on the application information, it is determined whether the target antenna is in a first holding state or a second holding state;

[0480] When the target antenna is in the first gripping state, the target antenna is tuned;

[0481] When the target antenna is in the second holding state, the target antenna is switched according to the signal strength of the target antenna.

[0482] In specific implementation, the first gripping state can correspond to the loose gripping state in the aforementioned embodiments, and the second gripping state can correspond to the full gripping state in the aforementioned embodiments. Specific embodiments can be referred to the aforementioned embodiments, and will not be repeated here.

[0483] Since the application's usage scenarios are relatively fixed, the antenna's holding state can be directly determined based on the application information, thus identifying whether the target antenna is in the first or second holding state. This can improve antenna system performance to some extent while simplifying the algorithm and reducing costs.

[0484] In one optional embodiment, the electronic device further includes an accelerometer sensor and a gyroscope sensor, wherein the accelerometer sensor is used to generate acceleration sensing data of the electronic device, and the gyroscope sensor is used to generate gyroscope sensing data of the electronic device.

[0485] After obtaining the service data of the electronic device, the method further includes:

[0486] Based on acceleration sensor data, gyroscope sensor data, and business data, the usage scenarios of electronic devices are determined; among them, the usage scenarios include the application information running on the electronic device and the screen orientation information of the electronic device.

[0487] Accordingly, based on business data, at least some antennas in the controlled electronic equipment are switched or tuned, including:

[0488] Depending on the usage scenario of the electronic device, control at least some of the antennas in the electronic device to switch or tune.

[0489] In practice, adding acceleration sensor data and gyroscope sensor data can more accurately determine the screen orientation of electronic devices.

[0490] Another embodiment of this application provides an antenna control method for an electronic device, the method comprising:

[0491] When the difference between the second signal strength value of the second communication antenna and the first signal strength value of the first communication antenna is greater than a first threshold and the first signal strength value is less than a third threshold, the third signal strength value of the third communication antenna is obtained; wherein, the third threshold is less than or equal to -60dB (for example, the third threshold is -65dB) and the first threshold is greater than or equal to 2dB (for example, the first threshold is 5dB).

[0492] When the difference between the third signal strength value and the first signal strength value is greater than the second threshold, the connection to the first communication antenna will be switched to the connection to the third communication antenna; wherein the second threshold is greater than or equal to 0dB;

[0493] In one optional embodiment, the first communication antenna is tuned when the difference between the third signal strength value and the first signal strength value is greater than a fourth threshold. The fourth threshold is less than the second threshold.

[0494] In this embodiment, the signal strength value can be RSSI or RSRP. This embodiment does not impose any restrictions. In some scenarios, it can also be SNR (signal to noise ratio) or SINR (signal to interference plus noise ratio).

[0495] Figure 18 is a flowchart illustrating an antenna control method based on a Wi-Fi network antenna system. Figure 18 shows the pure signal strength control algorithm scheme for the Wi-Fi 5G band antenna system shown in Figure 11A. In the figure, RSSI C0 is the first signal strength value, RSSI C1 is the second signal strength value, and RSSI C0TAS is the third signal strength value. The first communication antenna is Wi-Fi C0, the second communication antenna is Wi-Fi C1, and the third communication antenna is Wi-Fi C0TAS.

[0496] In the diagram, the process begins with a service signal trigger and proceeds as follows:

[0497] First, WIFI C0 and WIFI C1 are compared to determine whether the conditions RSSI C1 - RSSI C0 > x dB, where x ≥ 2, and RSSI C0 < y dB, where y ≤ -60 dB, are met. When the above conditions are not satisfied, the process ends. When the above conditions are satisfied, the RSSI value of WIFI C0 TAS is read. When RSSI C0TAS is greater than RSSI C0 by z dB, where z ≥ 0, the antenna switch is completed; otherwise, the process ends.

[0498] In one embodiment, to avoid the ping-pong effect, after the switch is made, a freeze time of m seconds is designed, where m ≥ 15.

[0499] In one embodiment, when the game lags, the algorithm is also triggered. When the lag is greater than n milliseconds, the process is started, where n ≥ 100. In addition to game or video lag, the algorithm also periodically starts the algorithm solution.

[0500] It should be noted that in an electronic device, for the WiFi antenna system, this pure signal strength control algorithm solution can be directly used, or a comprehensive decision can be made in combination with the usage scenarios of the foregoing embodiments.

[0501] Understandably, in this embodiment, the RSSI values ​​of the first and second communication antennas are first compared to determine if the first communication antenna is malfunctioning. If certain conditions are met, it indicates that the first communication antenna is malfunctioning. Then, the first and third communication antennas are compared to achieve a low threshold comparison. Furthermore, a freeze time is designed to avoid the ping-pong effect. It is understood that in some embodiments, the signal strength of the WIFI C1 and WIFI C0 antennas may differ in free space (FS), or the WIFI C1 reference antenna may be affected by hand grip in landscape mode. The algorithm prioritizes compensating for the signal strength difference of the reference antenna WIFI C1 in this state before comparing it with the WIFI C0 antenna. Therefore, the first threshold in this embodiment can be the relative difference between WIFI C0 and WIFI C1, i.e., the difference caused by hand grip or other factors affecting the performance of the WIFI C0 antenna after compensating for the original difference between WIFI C0 and WIFI C1. In this embodiment, WIFI C1 serves as the reference antenna, which can show situations where the WIFI C0 antenna experiences a significant signal strength drop due to hand grip or obstruction. In some scenarios, a telecommunications comparison is made between the Wi-Fi C0 and Wi-Fi C1 antennas. A significant difference in throughput or MIMO performance between the two antennas indicates that the Wi-Fi C0 antenna is malfunctioning or experiencing severe performance degradation due to hand handling or obstruction, requiring tuning or switching. This embodiment does not specifically limit the method of comparing the Wi-Fi C0 and Wi-Fi C1 antennas.

[0502] The simulation test results of the antenna system combined with the antenna control method in this embodiment are described below.

[0503] As shown in Figures 8A to 8D, the antenna system, combined with the antenna control method of this application, shows a 3dB+ improvement in the ±60° airspace when the top edge antenna is fully held in landscape mode; and a 1dB+ improvement in the ±60° airspace when the antenna is loosely held in landscape mode.

[0504] As shown in Figure 11A, the antenna system, combined with the antenna control method of this application, improves the antenna performance by 4 to 6 dB+ in the ±60° airspace when the screen is held horizontally with the hand fully gripping the top edge antenna; and improves the performance by 2 dB+ in the ±60° airspace when the screen is held horizontally with the hand partially gripping the antenna.

[0505] As shown in Figure 11B, the antenna system, combined with the antenna control method of this application, improves the antenna performance by 4 to 6 dB+ in the ±60° airspace when the top bezel antenna is fully held in landscape mode; and improves it by 2 dB+ in the ±60° airspace when the antenna is loosely held in landscape mode.

[0506] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
