Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an electronic device. Background Art

[0002] With technological advancements, electronic devices with communication capabilities, such as mobile phones, are becoming increasingly popular and powerful. Electronic devices often include antenna assemblies to enable these communications functions. However, the performance of antenna assemblies in electronic devices in related art still needs to be improved. Summary of the Invention

[0003] In a first aspect, an embodiment of the present application provides an electronic device, the electronic device having a first side, a second side, and a third side that are bent and connected in sequence, the third side being arranged opposite to the first side, the length of the second side being less than the length of the first side, and the length of the second side being less than the length of the third side; when the electronic device is in a portrait mode, the second side is the top side of the electronic device, the electronic device including an antenna assembly and a controller, the antenna assembly including:

[0004] A first antenna comprising a first radiator, the first radiator being located at a portion of the first side adjacent to the second side, the first radiator having a first ground end and a first free end, the first ground end being grounded, and the first free end being further away from the second side than the first ground end;

[0005] The second antenna includes a second radiator, which is located at a position of the third side adjacent to the second side, and the second radiator has a second ground end and a second free end, the second ground end is grounded, and the second free end is away from the second side compared to the second ground end; the controller is used to control one of the first antenna and the second antenna to be a transmitting antenna of the first frequency band and the other to be a receiving antenna of the first frequency band according to the posture of the electronic device, wherein the antenna performance of the one when supporting the first frequency band is better than the antenna performance of the other when supporting the first frequency band.

[0006] In summary, in the electronic device provided in the embodiment of the present application, the first radiator of the first antenna of the antenna assembly is located at a position where the first side is adjacent to the second side, and the first free end is away from the second side compared to the first ground end; the second radiator of the second antenna is located at a position where the third side is adjacent to the second side, and the second free end is away from the second side compared to the second ground end. Therefore, when the user holds the electronic device, it is not easy to completely block the first antenna and the second antenna, so that one of the first antenna and the second antenna has relatively good antenna performance in the first frequency band. The controller controls the one of the first antenna and the second antenna with a better signal to act as a transmitting antenna in the first frequency band, and the other to act as a receiving antenna in the first frequency band, according to the posture of the electronic device, so that the antenna assembly has better performance when transmitting electromagnetic wave signals in the first frequency band.

[0007] Furthermore, since the first radiator is located at a position where the first side is adjacent to the second side, when the electronic device is in portrait mode, if the second side is the top side of the electronic device in portrait mode, the first radiator is also located at the top of the electronic device. When the electronic device in portrait mode is held by a user, the first radiator is not easily blocked by the user's hand, thereby enabling the first antenna to have better communication performance in the first frequency band when the electronic device is in portrait mode. Correspondingly, since the second radiator is located at a position where the third side is adjacent to the second side, when the electronic device is in portrait mode, if the second side is the top side of the electronic device in portrait mode, the second radiator is also located at the top of the electronic device. When the electronic device in portrait mode is held by a user, the second radiator is not easily blocked by the user's hand, thereby enabling the second antenna to have better communication performance in the first frequency band when the electronic device is in portrait mode.

[0039] The technical solution of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments, not all embodiments. Based on the embodiments provided in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0040] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it necessarily refer to mutually exclusive, independent, or alternative embodiments to other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0041] The terms "first," "second," and so on, in the specification and claims of this application and the accompanying drawings are used to distinguish between different objects, not to describe a specific order. Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions.

[0042] An embodiment of the present application provides an electronic device 1. The electronic device 1 includes but is not limited to mobile phones, telephones, televisions, tablet computers (Pads), personal computers, laptop computers (PCs), vehicle-mounted devices, headphones, watches, wearable devices, and other devices that can send and receive electromagnetic wave signals. In the schematic diagram of the embodiment of the present application, the electronic device 1 is illustrated as a mobile phone. It can be understood that this should not be understood as a limitation on the electronic device 1 provided in the embodiment of the present application. The electronic device 1 provided in the embodiment of the present application is introduced. Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , Figure 1 A schematic diagram of an electronic device in a portrait mode according to an embodiment of the present application; Figure 2for Figure 1 A schematic diagram of a portion of the structure of the electronic device shown in FIG; Figure 3 for Figure 2 A schematic diagram of a portion of the structure of the antenna assembly shown in ;

[0043] Figure 4 for Figure 1 shows a partial circuit block diagram of an electronic device. The electronic device 1 has a first side 1a, a second side 1b, and a third side 1c that are bent and connected in sequence. The third side 1c is disposed opposite the first side 1a. When the electronic device is in portrait mode, the second side is the top side of the electronic device 1. The electronic device 1 includes an antenna assembly 10 and a controller 20. The antenna assembly 10 includes a first antenna 110 and a second antenna 120. The first antenna 110 includes a first radiator 111. The first radiator 111 is located at a portion of the first side 1a adjacent to the second side 1b. The first radiator 111 has a first grounding end 1111 and a first free end 1112. The first grounding end 1111 is grounded, and the first free end 1112 faces away from the second side 1b relative to the first grounding end 1111. The second antenna 120 includes a second radiator 121. The second radiator 121 is located at a portion of the third side 1c adjacent to the second side 1b. The second radiator 121 has a second grounding end 1211 and a second free end 1212. The second ground end 1211 is grounded, and the second free end 1212 is away from the second side 1b compared to the second ground end 1211. The controller 20 is configured to control one of the first antenna 110 and the second antenna 120 to function as a transmitting antenna in a first frequency band and the other to function as a receiving antenna in the first frequency band, based on the posture of the electronic device 1, wherein the antenna performance of the first antenna supporting the first frequency band is superior to the antenna performance of the other antenna supporting the first frequency band.

[0044] The electronic device 1 has a first side 1a, a second side 1b and a third side 1c that are bent and connected in sequence, and the third side 1c is arranged opposite to the first side 1a; specifically, one end of the second side 1b is bent and connected to one end of the first side 1a, and one end of the third side 1c is bent and connected to the other end of the second side 1b, and the third side 1c is opposite to the first side 1a and is arranged at a distance.

[0045] In this embodiment, the length of the second side 1b is less than the length of the first side 1a, and the length of the second side 1b is less than the length of the third side 1c. Therefore, the first side 1a is the long side of the electronic device 1, the second side 1b is the short side of the electronic device 1, and the third side 1c is the long side of the electronic device 1.

[0046] In this embodiment, when the electronic device 1 is in portrait mode, the second side 1b is located at the top of the electronic device 1, and the first side 1a and the third side 1c are both located at the side of the electronic device 1. In other words, when the electronic device 1 is in portrait mode, the second side 1b is the top side of the electronic device 1, and the first side 1a and the third side 1c are both side sides of the electronic device 1.

[0047] The first radiator 111 can be a laser direct structuring (LDS) radiator, or a flexible printed circuit (FPC) radiator, or a print direct structuring (PDS) radiator, or a metal branch radiator. When the antenna assembly 10 is applied to the electronic device 1, the first radiator 111 can be a mechanical design antenna (MDA) radiator designed using the metal insert of the electronic device 1 itself. For example, the first radiator 111 can be an antenna radiator designed using the middle frame 30 formed of plastic and metal of the electronic device 1. In addition, the first radiator 111 can also be a radiator of a metal frame antenna designed with a metal middle frame 30.

[0048] The first ground terminal 1111 is grounded, and may be, but is not limited to, electrically connected to the ground of the electronic device 1 via a conductive member (such as a connecting rib, a conductive spring, a conductive wire, or a conductive adhesive). The ground of the electronic device 1 includes, but is not limited to, at least one of the middle frame 30, the back cover 60, and the shielding of the display 50. In one embodiment, the first radiator 111 is a frame radiator formed using the metal middle frame 30 of the electronic device 1, and the first ground terminal 1111 is electrically connected to the main body of the middle frame 30 via a connecting rib for grounding.

[0049] The first free end 1112 faces away from the second side 1b compared to the first ground end 1111. Therefore, when the electronic device 1 is in portrait mode, when the second side 1b is the top side of the electronic device 1, the first free end 1112 faces downward compared to the first ground end 1111, and therefore, the opening of the first antenna 110 is also referred to as facing downward.

[0050] The second radiator 121 can be a laser direct structuring (LDS) radiator, or a flexible printed circuit (FPC) radiator, or a print direct structuring (PDS) radiator, or a metal branch radiator. When the antenna assembly 10 is applied to the electronic device 1, the second radiator 121 can be a mechanical design antenna (MDA) radiator designed using the metal insert of the electronic device 1 itself. For example, the second radiator 121 can be an antenna radiator designed using the middle frame 30 formed of plastic and metal of the electronic device 1. In addition, the second radiator 121 can also be a radiator of a metal frame antenna designed with a metal middle frame 30.

[0051] The second ground terminal 1211 is grounded, and may be, but is not limited to, electrically connected to the ground of the electronic device 1 via a conductive member (such as a connecting rib, a conductive spring, a conductive wire, or conductive adhesive). The ground of the electronic device 1 includes, but is not limited to, at least one of the middle frame 30, the back cover 60, and the shielding of the display 50. In one embodiment, the second radiator 121 is a frame radiator formed using the metal middle frame 30 of the electronic device 1, and the second ground terminal 1211 is electrically connected to the main body of the middle frame 30 via a connecting rib for grounding.

[0052] The second free end 1212 faces away from the second side 1b compared to the second ground end 1211. Therefore, when the electronic device 1 is in portrait mode, when the second side 1b is the top side of the electronic device 1, the second free end 1212 faces away from the second ground end 1211, and therefore, the opening of the second antenna 120 is also referred to as facing downward.

[0053] Please continue reading Figure 2 and Figure 3In one embodiment, the first radiator 111 and the second radiator 121 are both formed on the border of the middle frame 30 of the electronic device 1. Specifically, the electronic device 1 includes a middle frame 30. The middle frame 30 includes a frame body 300, a first border 310, a second border 320, and a third border 330. The first border 310 is arranged corresponding to the first side 1a of the electronic device 1. For example, the side of the first border 310 facing away from the frame body 300 is the first side 1a of the electronic device 1; alternatively, the first border 310 is adjacent to the first side 1a. The first border 310 is connected to one side of the frame body 300. The second border 320 is arranged corresponding to the second side 1b of the electronic device 1. For example, the side of the second border 320 facing away from the frame body 300 is the second side 1b of the electronic device 1; alternatively, the second border 320 is adjacent to the second side 1b. One end of the second border 320 is bent and connected to one end of the first border 310, and the length of the second border 320 is less than the length of the first border 310. The third frame 330 is arranged corresponding to the third side 1c of the electronic device 1. For example, the side line of the third frame 330 away from the frame body 300 is the third side 1c of the electronic device 1; or, the third frame 330 is arranged adjacent to the third side 1c. One end of the third frame 330 is bent and connected to the other end of the second frame 320, and the third frame 330 is arranged opposite to the first frame 310. The length of the third frame 330 is greater than the length of the second frame 320. Since the length of the second frame 320 is less than the length of the first frame 310, the length of the third frame 330 is greater than the length of the second frame 320. Therefore, the first frame 310 is also called the long frame of the middle frame 30, the second frame 320 is also called the short frame of the middle frame 30, and the third frame 330 is also called the long frame of the middle frame 30. A first gap 310a is provided between the first frame 310 and the frame body 300. The first frame 310 has a first gap 310b, which communicates with the first gap 310a and extends through the end surface of the first frame 310 facing away from the frame body 300. The first gap 310a and the first gap 310b together define the first radiator 111. The first gap 310b faces away from the first grounding end 1111 and defines the end surface of the first free end 1112 facing away from the first grounding end 1111.

[0054] In one embodiment, when the first antenna 110 supports the first frequency band, for example, when the first antenna 110 radiates electromagnetic wave signals in the first frequency band, the first radiator 111 radiates electromagnetic wave signals in the first frequency band through the first gap 310b; when the first antenna 110 receives electromagnetic wave signals in the first frequency band, the first radiator 111 receives electromagnetic wave signals in the first frequency band through the first gap 310b. If the first gap 310b is blocked or held, the antenna performance of the first antenna 110 supporting the first frequency band is poor. If the first gap 310b is not blocked and is not held, the antenna performance of the first antenna 110 supporting the first frequency band is good.

[0055] Please continue reading Figure 2 and Figure 3 A second gap 330a is defined between the third frame 330 and the frame body 300. The third frame 330 has a second gap 330b, which communicates with the second gap 330a and extends through the end surface of the third frame 330 facing away from the frame body 300. The second gap 330a and the second gap 330b together define the second radiator 121. The second gap 330b faces away from the second grounding terminal 1211 and defines the end surface of the second free end 1212 facing away from the second grounding terminal 1211.

[0056] In one embodiment, when the second antenna 120 supports the first frequency band, for example, when the second antenna 120 radiates electromagnetic wave signals in the first frequency band, the second radiator 121 radiates electromagnetic wave signals in the first frequency band through the second gap 330b; when the second antenna 120 receives electromagnetic wave signals in the first frequency band, the second radiator 121 receives electromagnetic wave signals in the first frequency band through the second gap 330b. If the second gap 330b is blocked or held, the antenna performance of the second antenna 120 supporting the first frequency band is poor. If the second gap 330b is not blocked and is not held, the antenna performance of the second antenna 120 supporting the first frequency band is good.

[0057] The antenna performance of the first antenna 110 supporting the first frequency band may include the performance of parameters such as the reference signal received power (RSRP) or the received signal strength (RSSI) of the first antenna 110 supporting the first frequency band. Correspondingly, the antenna performance of the second antenna 120 supporting the first frequency band may be the reference signal received power (RSRP) or the received signal strength (RSSI) of the second antenna 120 supporting the first frequency band. When comparing the antenna performance of the first antenna 110 supporting the first frequency band with the antenna performance of the second antenna 120 supporting the first frequency band, the comparison is between the performance of the same parameter of the first antenna 110 supporting the first frequency band and the performance of the second antenna 120 supporting the first frequency band, for example, both are compared in terms of RSRP or both are compared in terms of RSSI.

[0058] Please also refer to Figure 2 and Figure 3 In this embodiment, the first antenna 110 includes a first radiator 111 and a first feed source S1. The first radiator 111 includes a first ground end 1111, a first free end 1112, and a first feed point P1 located between the first ground end 1111 and the first free end 1112. The first feed source S1 is electrically connected to the first feed point P1 to excite the first radiator 111 to support the first frequency band.

[0059] Accordingly, in this embodiment, the second antenna 120 includes a second radiator 121 and a second feed source S2. The second radiator 121 includes a second ground end 1211, a second free end 1212, and a second feed point P2 located between the second ground end 1211 and the second free end 1212. The second feed source S2 is electrically connected to the second feed point P2 to excite the second radiator 121 to support the first frequency band.

[0060] In one embodiment, the first frequency band includes a medium frequency band, a high frequency band, a WiFi 2.4G frequency band, or an N78 frequency band.

[0061] The posture of the electronic device 1 includes but is not limited to a landscape state (such as the first landscape state and the second landscape state described later) and a portrait state; and also includes a tilted state, etc. This application does not limit the posture of the device 1.

[0062] When the posture of the electronic device 1 is different, when the user uses the electronic device 1, the antenna performance of the first antenna 110 when supporting the first frequency band is different from the antenna performance of the second antenna 120 when supporting the first frequency band. The controller 20 is electrically connected to the first antenna 110, and the controller 20 is electrically connected to the second antenna 120. The controller 20 controls one of the first antenna 110 and the second antenna 120 to be a transmitting antenna of the first frequency band and the other to be a receiving antenna of the first frequency band according to the posture of the electronic device 1. For example, in one embodiment, when the electronic device 1 is in the current posture, the antenna performance of the first antenna 110 supporting the first frequency band is better than the antenna performance of the second antenna 120 supporting the first frequency band, then the controller 20 controls the first antenna 110 to transmit electromagnetic wave signals of the first frequency band, and controls the second antenna 120 to receive electromagnetic wave signals of the first frequency band. When the first antenna 110 transmits electromagnetic wave signals in the first frequency band, the first antenna 110 is a transmitting antenna in the first frequency band; when the second antenna 120 receives electromagnetic wave signals in the first frequency band, the second antenna 120 is a receiving antenna in the first frequency band. In another embodiment, when the electronic device 1 is in the current posture, the antenna performance of the second antenna 120 supporting the first frequency band is better than the antenna performance of the first antenna 110 supporting the first frequency band, then the controller 20 controls the second antenna 120 to transmit electromagnetic wave signals in the first frequency band and controls the first antenna 110 to receive electromagnetic wave signals in the first frequency band. When the second antenna 120 transmits electromagnetic wave signals in the first frequency band, the second antenna 120 is a transmitting antenna in the first frequency band; when the first antenna 110 receives electromagnetic wave signals in the first frequency band, the first antenna 110 is a receiving antenna in the first frequency band.

[0063] It can be understood that when the first antenna 110 is a transmitting antenna in the first frequency band, the first antenna 110 transmits electromagnetic wave signals in the first frequency band through the first radiator 111. When the first antenna 110 is a receiving antenna in the first frequency band, the first antenna 110 receives electromagnetic wave signals in the first frequency band through the first radiator 111. Correspondingly, when the second antenna 120 is a transmitting antenna in the first frequency band, the second antenna 120 transmits electromagnetic wave signals in the first frequency band through the second radiator 121. When the second antenna 120 is a receiving antenna in the first frequency band, the second antenna 120 receives electromagnetic wave signals in the first frequency band through the second radiator 121.

[0064] In summary, in the electronic device 1 provided in the embodiments of the present application, the first radiator 111 of the first antenna 110 of the antenna assembly 10 is located at a position adjacent to the second side 1b on the first side 1a, and the first free end 1112 faces away from the second side 1b compared to the first ground end 1111. The second radiator 121 of the second antenna 120 is located at a position adjacent to the second side 1b on the third side 1c, and the second free end 1212 faces away from the second side 1b compared to the second ground end 1211. Therefore, when a user holds the electronic device 1, it is unlikely that both the first antenna 110 and the second antenna 120 will be completely blocked, resulting in one of the first antenna 110 and the second antenna 120 having relatively good antenna performance in the first frequency band. The controller 20 controls the first antenna 110 or the second antenna 120 with the better signal to act as the transmitting antenna in the first frequency band, while the other acts as the receiving antenna in the first frequency band, based on the posture of the electronic device 1. This ensures that the antenna assembly 10 has better performance when transmitting electromagnetic wave signals in the first frequency band.

[0065] Furthermore, because the first radiator 111 is located at a portion of the first side 1a adjacent to the second side 1b, when the electronic device 1 is in portrait mode, if the second side 1b is the top side of the electronic device 1 in portrait mode, the first radiator 111 is also located at the top of the electronic device 1. When the electronic device 1 in portrait mode is held by a user, the first radiator 111 is not easily blocked by the user's hand, thereby enabling the first antenna 110 to have good communication performance in the first frequency band when the electronic device 1 is in portrait mode. Accordingly, because the second radiator 121 is located at a portion of the third side 1c adjacent to the second side 1b, when the electronic device 1 is in portrait mode, if the second side 1b is the top side of the electronic device 1 in portrait mode, the second radiator 121 is also located at the top of the electronic device 1. When the electronic device 1 in portrait mode is held by a user, the second radiator 121 is not easily blocked by the user's hand, thereby enabling the second antenna 120 to have good communication performance in the first frequency band when the electronic device 1 is in portrait mode.

[0066] See also Figure 1The electronic device 1 provided in one embodiment of the present application further includes a middle frame 30, a display screen 50 and a back cover 60. The display screen 50 is arranged on one side of the middle frame 30. The display screen 50 is a component in the electronic device 1 that implements the display function. When the electronic device is in the first horizontal screen state or the electronic device is in the second horizontal screen state, the display screen of the electronic device faces the user. When the electronic device 1 is in the vertical screen state, the display screen 50 of the electronic device 1 faces the user. The back cover 60 is arranged on the other side of the middle frame 30. In other words, the back cover 60 and the display screen 50 are respectively arranged on opposite sides of the middle frame 30. The back cover 60 cooperates with the middle frame 30 to form a receiving space to accommodate the functional components of the electronic device 1, such as a rear camera, a battery, etc. It can be understood that the description of other components in the electronic device 1 should not be understood as a limitation on the antenna assembly 10 in the electronic device 1 provided in the embodiment of the present application.

[0067] Please also refer to Figures 2 to 4 、 Figure 5 and Figure 6 , Figure 5 A schematic diagram of an electronic device in a first horizontal screen state provided by an embodiment of the present application; Figure 6 for Figure 5 is a schematic diagram of a model of an electronic device in a first landscape state when held by a user with both hands. In this embodiment, the electronic device 1 has a landscape state, and the landscape state includes a first landscape state. If the electronic device 1 is in the first landscape state: the first side 1a is located at the top of the electronic device 1 relative to the third side 1c, the controller 20 controls the first antenna 110 to be a transmitting antenna supporting the first frequency band, and the second antenna 120 to be a receiving antenna supporting the first frequency band.

[0068] When the electronic device 1 is in the landscape mode, the electronic device 1 has two landscape modes depending on the position of the first side 1a of the electronic device 1. For the sake of convenience, the two landscape modes of the electronic device 1 are named the first landscape mode and the second landscape mode.

[0069] Specifically, when the electronic device 1 is in the first landscape state, the first side 1a is located at the top of the electronic device 1, the third side 1c is located at the bottom of the electronic device 1, and the second side 1b is adjacent to the left hand of the electronic device 1. Therefore, when the electronic device 1 is in the first landscape state and is held by the user with both hands, the first antenna 110 is less likely to be blocked by the user's hands than the second antenna 120. Specifically, when the electronic device 1 is in the first landscape state and is held by the user with both hands, the first gap 310b (also known as the gap) at the first free end 1112 of the first radiator 111 of the first antenna 110 is farther from the user's hand, and the user's hand has less impact on the antenna performance of the first antenna 110 when supporting the first frequency band. In contrast, the second gap 330b at the second free end 1212 of the second radiator 121 of the second antenna 120 is closer to the user's hand, and the user's hand has a greater impact on the antenna performance of the second antenna 120 when supporting the first frequency band. It can be seen that when the electronic device 1 is in the first horizontal screen state and is held by the user with both hands, the antenna performance of the first antenna 110 supporting the first frequency band is better than the antenna performance of the second antenna 120 supporting the first frequency band.

[0070] The posture of the electronic device 1 before it is in the first landscape state is named a first prior posture. When the electronic device 1 is in the first prior posture, the controller 20 controls one of the first antenna 110 and the second antenna 120 to function as a transmitting antenna in a first frequency band and the other to function as a receiving antenna in the first frequency band, wherein the antenna performance of the first antenna when supporting the first frequency band is superior to the antenna performance of the other when supporting the first frequency band.

[0071] Specifically, if the electronic device 1 is in the first prior posture, the first antenna 110 is a transmitting antenna supporting the first frequency band, and the second antenna 120 is a receiving antenna supporting the first frequency band. Then, when the posture of the electronic device 1 switches from the first prior posture to the first horizontal screen state, the controller 20 maintains the first antenna 110 as the transmitting antenna supporting the first frequency band, and the second antenna 120 as the receiving antenna supporting the first frequency band.

[0072] If the electronic device 1 is in the first prior posture, the first antenna 110 is a receiving antenna supporting the first frequency band, and the second antenna 120 is a transmitting antenna supporting the first frequency band. Then, when the posture of the electronic device 1 switches from the first prior posture to the first landscape state, the controller 20 switches the transmitting antenna supporting the first frequency band from the second antenna 120 in the first prior posture to the first antenna 110 in the first landscape state, and switches the receiving antenna supporting the first frequency band from the first antenna 110 in the first prior posture to the second antenna 120 in the first landscape state.

[0073] To sum up, if the electronic device 1 is in the first horizontal screen state: the first side 1a is located at the top of the electronic device 1 compared to the third side 1c, the controller 20 controls the first antenna 110 to be a transmitting antenna supporting the first frequency band, and the second antenna 120 is a receiving antenna of the first frequency band; thereby, when the electronic device 1 is in the first horizontal screen state, the antenna assembly 10 has better transmission performance in the first frequency band.

[0074] Furthermore, in one embodiment, the electronic device 1 further includes a fourth side 1d (see Figure 1 and Figure 2 ), the fourth side 1d is connected to the first side 1a by bending, the fourth side 1d is connected to the third side 1c by bending, and the fourth side 1d is arranged opposite to the second side 1b.

[0075] In combination with the electronic device 1 provided in the previous embodiment, in one embodiment, the electronic device 1 further includes a Universal Serial Bus (USB) port. Typically, the USB port 80 is provided corresponding to the fourth side 1d. Therefore, when the electronic device 1 is in the first landscape state, the USB port 80 faces right, and the first landscape state is also referred to as the USB port 80 right-facing state or USB to the right. When the electronic device 1 is in the second landscape state, the USB port 80 faces left, and the second landscape state is also referred to as the USB port 80 left-facing state or USB to the left. It is understandable that the electronic device 1 provided in the embodiment of the present application may not include the USB port 80, and the embodiment of the present application does not limit whether the electronic device 1 includes a USB port.

[0076] See also Figures 2 to 4 、 Figure 7 、 Figure 8 , Figure 7 A schematic diagram of an electronic device in a second horizontal screen state provided by an embodiment of the present application; Figure 8 for Figure 7is a schematic diagram of a model of an electronic device in a second landscape state when held by a user with both hands. The landscape state also includes a second landscape state. If the electronic device 1 is in the second landscape state: the third side 1c is located at the top of the electronic device 1 compared to the first side 1a, the controller 20 controls the second antenna 120 to be a transmitting antenna supporting the first frequency band, and the first antenna 110 to be a receiving antenna supporting the first frequency band.

[0077] Specifically, when the electronic device 1 is in the second landscape state, the first side 1a is located at the bottom of the electronic device 1, the third side 1c is located at the top of the electronic device 1, and the second side 1b is adjacent to the right hand of the electronic device 1. Therefore, when the electronic device 1 is in the second landscape state and is held by the user with both hands, the second antenna 120 is less likely to be blocked by the user's hands than the first antenna 110. Specifically, when the electronic device 1 is in the second landscape state and is held by the user with both hands, the second gap 330b (also known as the gap) at the second free end 1212 of the second radiator 121 of the second antenna 120 is farther from the user's hand, and the user's hand has less impact on the antenna performance of the second antenna 120 when supporting the first frequency band. In contrast, the first gap 310b at the first free end 1112 of the first radiator 111 of the first antenna 110 is closer to the user's hand, and the user's hand has a greater impact on the antenna performance of the first antenna 110 when supporting the first frequency band. It can be seen that when the electronic device 1 is in the second horizontal screen state and is held by the user with both hands, the antenna performance of the second antenna 120 supporting the first frequency band is better than the antenna performance of the first antenna 110 supporting the first frequency band.

[0078] The posture of the electronic device 1 before it is in the first landscape state is referred to as a second prior posture. When the electronic device 1 is in the second online posture, the controller 20 controls one of the first antenna 110 and the second antenna 120 to function as a transmitting antenna in the first frequency band and the other to function as a receiving antenna in the first frequency band, wherein the antenna performance of the first antenna when supporting the first frequency band is superior to the antenna performance of the other when supporting the first frequency band.

[0079] Specifically, if the electronic device 1 is in the second prior posture, the first antenna 110 is a transmitting antenna supporting the first frequency band, and the second antenna 120 is a receiving antenna supporting the first frequency band. Then, when the posture of the electronic device 1 switches from the second prior posture to the second landscape state, the controller 20 switches the transmitting antenna supporting the first frequency band from the first antenna 110 in the second prior posture to the second antenna 120 in the second landscape state, and switches the receiving antenna supporting the first frequency band from the second antenna 120 in the second prior posture to the first antenna 110 in the second landscape state.

[0080] If the electronic device 1 is in the second prior posture, the second antenna 120 is a transmitting antenna supporting the first frequency band, and the first antenna 110 is a receiving antenna supporting the first frequency band. Then, when the posture of the electronic device 1 switches from the second prior posture to the second landscape state, the controller 20 maintains the second antenna 120 as the transmitting antenna supporting the first frequency band, and the first antenna 110 as the receiving antenna supporting the first frequency band.

[0081] To sum up, if the electronic device 1 is in the second horizontal screen state: the third side 1c is located at the top of the electronic device 1 compared to the first side 1a, the controller 20 controls the second antenna 120 to be a transmitting antenna supporting the first frequency band, and the first antenna 110 to be a receiving antenna supporting the first frequency band; thereby, when the electronic device 1 is in the second horizontal screen state, the antenna assembly 10 has better transmission performance in the first frequency band.

[0082] See also Figure 2 、 Figure 3 and Figure 9 , Figure 9 for Figure 3 Schematic diagram of the dimensions of some structures in the antenna assembly shown in FIG. A distance d1 from the end surface of the first free end 1112 facing away from the first ground end 1111 to the second side 1b satisfies the following conditions: 29 mm ≤ d1 ≤ 35 mm. A distance d2 from the end surface of the second free end 1212 facing away from the second ground end 1211 to the second side 1b satisfies the following conditions: 29 mm ≤ d2 ≤ 35 mm.

[0083] A distance d1 from the end surface of the first free end 1112 facing away from the first ground end 1111 to the second side 1b may be, but is not limited to, 29 mm, 30 mm, 31 mm, 32 mm, 33 mm, 34 mm, or 35 mm.

[0084] When the distance d1 from the end surface of the first free end 1112 away from the first ground end 1111 to the second edge 1b satisfies: 29mm≤d1≤35mm, the electronic device 1 can be in the first horizontal screen state and held by both hands of the user. The break at the first free end 1112 (that is, the first gap 310b) is not easy to be held and not easy to be blocked, so that when the electronic device 1 is in the first horizontal screen state, the first antenna 110 has better performance in supporting the first frequency band.

[0085] Correspondingly, a distance d2 from the end surface of the second free end 1212 facing away from the second ground end 1211 to the second side 1b may be, but is not limited to, 29 mm, 30 mm, 31 mm, 32 mm, 33 mm, 34 mm, or 35 mm.

[0086] When the distance d2 from the end surface of the second free end 1212 away from the second ground end 1211 to the second edge 1b satisfies: 29mm≤d2≤35mm, the electronic device 1 can be in the second horizontal screen state and held by both hands of the user. The break at the second free end 1212 (that is, the second gap 330b) is not easy to be held and not easy to be blocked, so that when the electronic device 1 is in the second horizontal screen state, the second antenna 120 supports the first frequency band with better performance.

[0087] It is understandable that in one embodiment, d2 = d1. In this way, the break at the first free end 1112 of the first radiator 111 of the first antenna 110 and the break at the second free end 1212 of the second radiator 121 of the second antenna 120 can be symmetrical, thereby making the electronic device 1 have a better appearance.

[0088] It can be understood that in another embodiment, d2≠d1, as long as the following conditions are satisfied: 29mm≤d1≤35mm; 29mm≤d2≤35mm.

[0089] In this embodiment, the distance d1 from the end surface of the first free end 1112 away from the first ground end 1111 to the second side 1b satisfies: 29mm≤d1≤35mm, and the distance d2 from the end surface of the second free end 1212 away from the second ground end 1211 to the second side 1b satisfies: 29mm≤d2≤35mm; this ensures that when the electronic device 1 is in the first horizontal screen state and is held by both hands or in the second horizontal screen state and is held by both hands, the first antenna 110 and the second antenna 120 will not be completely blocked, and the controller 20 controls the one of the first antenna 110 and the second antenna 120 with better antenna performance supporting the first frequency band to be the transmitting antenna of the first frequency band and the other to be the receiving antenna of the first frequency band according to the state of the electronic device 1 and the antenna performance of the first antenna 110 when supporting the first frequency band and the antenna performance of the second antenna 120 when supporting the first frequency band, so that the electronic device 1 has better antenna performance in the first frequency band.

[0090] Furthermore, in one embodiment, the first frequency band includes a medium frequency band or a high frequency band. A quarter wavelength mode from the first free end 1112 of the first radiator 111 to the first ground end 1111 supports the first frequency band.

[0091] The first frequency band includes a medium frequency band or a high frequency band, and can meet the communication requirements of the electronic device 1 in the medium frequency band or the high frequency band.

[0092] In this embodiment, the quarter-wavelength mode from the first free end 1112 of the first radiator 111 to the first ground end 1111 supports a "wavelength" in the first frequency band corresponding to the center frequency point (also called the center frequency) of the first frequency band.

[0093] The quarter-wavelength mode is also called the fundamental mode, and the frequency band supported by the fundamental mode generally has higher efficiency. In the electronic device 1 provided in the embodiment of the present application, the quarter-wavelength mode from the first free end 1112 to the first ground end 1111 of the first radiator 111 supports the first frequency band, that is, the fundamental mode of the first radiator 111 supports the first frequency band. Therefore, the first radiator 111 of the first antenna 110 has higher efficiency when supporting the first frequency band.

[0094] When the first gap 310b limits the end face of the first free end 1112 facing away from the first ground end 1111, the quarter-wavelength mode from the first free end 1112 of the first radiator 111 to the first ground end 1111 supports the first frequency band, which can also be called the quarter-wavelength mode between the first gap 310b and the first ground end 1111 supporting the first frequency band, or the quarter-wavelength mode of the entire branch section of the first radiator 111 supporting the first frequency band.

[0095] See also Figure 10 , Figure 10 This is a schematic diagram of an antenna assembly provided in another embodiment of the present application. The first radiator 111 has a first feeding point P1, and the second radiator 121 has a second feeding point P2. The antenna assembly 10 also includes a third antenna 130. The third antenna 130 includes a third radiator 131, and the third radiator 131 includes a third grounding end 1311, a third free end 1312, and a third feeding point P3. The third grounding end 1311 is grounded, and the third free end 1312 is opposite to and spaced from the first free end 1112 to form a first gap 310b. The quarter-wavelength pattern from the third grounding end 1311 to the third free end 1312 of the third radiator 131 is used to support a second frequency band, the frequency of which is lower than the frequency of the first frequency band. When the first frequency band includes a high frequency band, the quarter-wavelength pattern from the third feeding point P3 of the third radiator 131 to the third grounding end 1311 is also used to support the first frequency band.

[0096] The third radiator 131 can be a laser direct structuring (LDS) radiator, or a flexible printed circuit (FPC) radiator, or a print direct structuring (PDS) radiator, or a metal branch radiator. When the antenna assembly 10 is applied to the electronic device 1, the third radiator 131 can be a mechanical design antenna (MDA) radiator designed using the metal insert of the electronic device 1 itself. For example, the third radiator 131 can be an antenna radiator designed using the middle frame 30 formed of plastic and metal of the electronic device 1. In addition, the third radiator 131 can also be a radiator of a metal frame antenna designed with a metal middle frame 30.

[0097] The third ground terminal 1311 is grounded, and may be, but is not limited to, electrically connected to the ground of the electronic device 1 via a conductive member (such as a connecting rib, a conductive spring, a conductive wire, or a conductive adhesive). The ground of the electronic device 1 includes, but is not limited to, at least one of the middle frame 30, the back cover 60, and the shielding of the display 50. In one embodiment, the third radiator 131 is a frame radiator formed using the metal middle frame 30 of the electronic device 1. The third ground terminal 1311 is electrically connected to the main body of the middle frame 30 via a connecting rib for grounding.

[0098] The third antenna 130 further includes a third feed source S3. The third feed source S3 is electrically connected to a third feed point P3 to stimulate the third radiator 131 to support the second frequency band. Thus, the antenna assembly 10 of the electronic device 1 can support the first and second frequency bands, meeting the communication requirements of the electronic device 1 in the first and second frequency bands.

[0099] The frequency of the second frequency band is lower than the frequency of the first frequency band. In one embodiment, the first frequency band includes a mid-frequency band or a high-frequency band, and the second frequency band includes a low-frequency band.

[0100] In this embodiment, the third radiator 131 is also located on the first side 1 a . The third ground end 1311 of the third radiator 131 is further away from the second side 1 b than the third free end 1312 .

[0101] In this embodiment, the first radiator 111, the second radiator 121, and the third radiator 131 are all formed on the frame of the middle frame 30 of the electronic device 1. Specifically, the third radiator 131 is located on the first frame 310. A third gap 310c is defined between the third radiator 131 and the frame body 300. The third gap 310c is connected to the first gap 310a, and the third gap 310c is connected to the first gap 310b.

[0102] The quarter-wavelength mode from the third ground end 1311 to the third free end 1312 of the third radiator 131 is used to support the "wavelength" in the second frequency band, which refers to the wavelength corresponding to the center frequency point (or center frequency) of the second frequency band. The quarter-wavelength mode is also called the fundamental mode, and the frequency band supported by the fundamental mode usually has higher efficiency. The quarter-wavelength mode from the third ground end 1311 to the third free end 1312 of the third radiator 131 is used to support the second frequency band, that is, the fundamental mode of the entire branch of the third radiator 131 supports the second frequency band. Therefore, the third radiator 131 of the third antenna 130 has higher efficiency when supporting the second frequency band.

[0103] Since the third free end 1312 is opposite to and spaced from the first free end 1112 to form a first gap 310b, the first gap 310b is also referred to as defining the first free end 1112 and the third free end 1312. A quarter-wavelength mode from the third ground end 1311 to the third free end 1312 of the third radiator 131 supports the second frequency band, which is also referred to as the quarter-wavelength mode from the third ground end 1311 to the first gap 310b supports the second frequency band, or the quarter-wavelength mode from the first gap 310b to the third ground end 1311 supports the second frequency band, or the quarter-wavelength mode of the entire branch section of the third radiator 131 supports the second frequency band.

[0104] As described above, the quarter-wavelength mode from the first free end 1112 of the first radiator 111 to the first ground end 1111 supports the first frequency band. When the first frequency band includes a high frequency band, the quarter-wavelength mode from the third feeding point P3 of the third radiator 131 to the third ground end 1311 is also used to support the first frequency band. The third free end 1312 is opposite to the first free end 1112 and is spaced apart to form a first gap 310b. Therefore, the third radiator 131 is coupled to the first radiator 111 through the first gap 310b. When the first frequency band includes a high frequency band, the third radiator 131 couples energy from the first radiator 111 and also supports the high frequency band. Therefore, when the first frequency band includes a high frequency band, not only can the first radiator 111 be used to support the first frequency band, but the part between the third feeding point P3 of the third radiator 131 and the third ground end 1311 can also be used to support the first frequency band, so that the antenna assembly 10 has better antenna performance in the first frequency band.

[0105] Furthermore, in one embodiment, a quarter-wavelength mode from the first free end 1112 of the first radiator 111 to the first ground end 1111 supports a third frequency band, and a three-quarter-wavelength mode from the third free end 1312 of the third radiator 131 to the third ground end 1311 supports a third frequency band.

[0106] As can be seen from the above description, the first radiator 111 of the first antenna 110 supports the first frequency band, and the first radiator 111 supports the third frequency band, so that the first antenna 110 can meet the communication requirements of the first frequency band and the third frequency band.

[0107] The quarter-wavelength mode from the first free end 1112 of the first radiator 111 to the first ground end 1111 supports the third frequency band. The "wavelength" in this context refers to the wavelength corresponding to the center frequency (or center frequency) of the third frequency band. A quarter-wavelength mode is also called a fundamental mode, and the frequency band supported by the fundamental mode generally has higher efficiency. The quarter-wavelength mode from the first free end 1112 of the first radiator 111 to the first ground end 1111 supports the third frequency band. Therefore, the first radiator 111 has higher efficiency when supporting the third frequency band.

[0108] The quarter-wavelength mode from the first free end 1112 of the first radiator 111 to the first ground end 1111 supports the third frequency band, which can also be called the quarter-wavelength mode from the first gap 310b to the first ground end 1111 supports the third frequency band, or the quarter-wavelength mode of the entire branch node of the first radiator 111 supports the third frequency band.

[0109] The three-quarter wavelength mode from the third free end 1312 of the third radiator 131 to the third ground end 1311 supports a third frequency band. The “wavelength” in the third frequency band refers to the wavelength corresponding to the center frequency point (or center frequency) of the third frequency band.

[0110] When the antenna assembly 10 supports the third frequency band, it not only utilizes the quarter-wavelength mode from the first free end 1112 of the first radiator 111 to the first ground end 1111 to support the third frequency band, but also utilizes the three-quarter-wavelength mode from the third free end 1312 of the third radiator 131 to the third ground end 1311 to support the third frequency band, thereby enabling the antenna assembly 10 to have better communication performance in the third frequency band.

[0111] In one embodiment, the first frequency band includes a medium frequency band or a high frequency band, the second frequency band includes a low frequency band, and the third frequency band includes an N78 frequency band.

[0112] In one embodiment, the first frequency band includes a medium frequency band or a high frequency band. A quarter-wavelength mode from the second free end 1212 of the second radiator 121 to the second ground end 1211 supports the first frequency band.

[0113] The first frequency band includes a medium frequency band or a high frequency band, and can meet the communication requirements of the electronic device 1 in the medium frequency band or the high frequency band.

[0114] In this embodiment, the quarter-wavelength mode from the second free end 1212 of the second radiator 121 to the second ground end 1211 supports a wavelength in the first frequency band corresponding to the center frequency point (also called the center frequency) of the first frequency band.

[0115] The quarter-wavelength mode is also called the fundamental mode, and the frequency band supported by the fundamental mode generally has higher efficiency. In the electronic device 1 provided in the embodiment of the present application, the quarter-wavelength mode from the second free end 1212 to the second ground end 1211 of the second radiator 121 supports the first frequency band, that is, the fundamental mode of the second radiator 121 supports the first frequency band. Therefore, the second radiator 121 of the second antenna 120 has higher efficiency when supporting the first frequency band.

[0116] When the second gap 330b limits the end face of the second free end 1212 facing away from the second ground end 1211, the quarter-wavelength mode from the second free end 1212 of the second radiator 121 to the second ground end 1211 supports the first frequency band, which can also be called the quarter-wavelength mode between the second gap 330b and the second ground end 1211 supports the first frequency band, or the quarter-wavelength mode of the entire branch of the second radiator 121 supports the first frequency band.

[0117] Please refer again Figure 10 , the antenna assembly 10 also includes a fourth antenna 140. The fourth antenna 140 includes a fourth radiator 141, and the fourth radiator 141 includes a fourth grounding end 1411, a fourth free end 1412, and a fourth feeding point P4. The fourth grounding end 1411 is grounded, and the fourth free end 1412 is opposite to and spaced from the second free end 1212 to form a second gap 330b. The quarter-wavelength pattern from the fourth grounding end 1411 to the fourth free end 1412 of the fourth radiator 141 is used to support a second frequency band, and the frequency of the second frequency band is lower than the frequency of the first frequency band. When the first frequency band includes a high frequency band, the quarter-wavelength pattern from the fourth feeding point P4 to the fourth grounding end 1411 of the fourth radiator 141 is also used to support the first frequency band.

[0118] The fourth radiator 141 can be a laser direct structuring (LDS) radiator, or a flexible printed circuit (FPC) radiator, or a print direct structuring (PDS) radiator, or a metal branch radiator. When the antenna assembly 10 is applied to the electronic device 1, the fourth radiator 141 can be a mechanical design antenna (MDA) radiator designed using the metal insert of the electronic device 1 itself. For example, the fourth radiator 141 can be an antenna radiator designed using the middle frame 30 formed of plastic and metal of the electronic device 1. In addition, the fourth radiator 141 can also be a radiator of a metal frame antenna designed with a metal middle frame 30.

[0119] The fourth ground terminal 1411 is grounded, and may be, but is not limited to, electrically connected to the ground of the electronic device 1 via a conductive member (such as a connecting rib, a conductive spring, a conductive wire, or a conductive adhesive). The ground of the electronic device 1 includes, but is not limited to, at least one of the middle frame 30, the back cover 60, and the shielding of the display 50. In one embodiment, the fourth radiator 141 is a frame radiator formed using the metal middle frame 30 of the electronic device 1. The fourth ground terminal 1411 is electrically connected to the main body of the middle frame 30 via a connecting rib for grounding.

[0120] The fourth antenna 140 further includes a fourth feed source S4. The fourth feed source S4 is electrically connected to a fourth feed point P4 to stimulate the fourth radiator 141 to support the second frequency band. Thus, the antenna assembly 10 of the electronic device 1 can support the first frequency band and the second frequency band, meeting the communication requirements of the electronic device 1 in the first frequency band and the second frequency band.

[0121] The frequency of the second frequency band is lower than the frequency of the first frequency band. In one embodiment, the first frequency band includes a mid-frequency band or a high-frequency band, and the second frequency band includes a low-frequency band.

[0122] In this embodiment, the fourth radiator 141 is also located on the third side 1 c . The fourth ground end 1411 of the fourth radiator 141 is further away from the second side 1 b than the fourth free end 1412 .

[0123] In this embodiment, the antenna assembly 10 further includes the fourth antenna 140, which is incorporated into an antenna assembly 10 that also includes the first antenna 110, the second antenna 120, and the third antenna 130. However, this should not be construed as limiting the antenna assembly 10 provided in the embodiment of this application. The antenna assembly 10 further includes the fourth antenna 140, which can also be incorporated into an antenna assembly 10 that does not include the third antenna 130.

[0124] In this embodiment, the first radiator 111, the second radiator 121, and the third radiator 131 are all formed on the frame of the middle frame 30 of the electronic device 1. Specifically, the third radiator 131 is located on the first frame 310. A third gap 310c is defined between the third radiator 131 and the frame body 300. The third gap 310c is connected to the first gap 310a, and the third gap 310c is connected to the first gap 310b.

[0125] The fourth radiator 141 is formed on the edge of the middle frame 30 of the electronic device 1. Specifically, the fourth radiator 141 is located on the third edge 330. A fourth gap 330c is defined between the fourth radiator 141 and the frame body 300. The fourth gap 330c is connected to the second gap 330a, and the fourth gap 330c is connected to the second gap 330b.

[0126] The quarter-wavelength mode from the fourth ground end 1411 to the fourth free end 1412 of the fourth radiator 141 is used to support the "wavelength" in the second frequency band, which refers to the wavelength corresponding to the center frequency point (or center frequency) of the second frequency band. The quarter-wavelength mode is also called the fundamental mode, and the frequency band supported by the fundamental mode usually has higher efficiency. The quarter-wavelength mode from the fourth ground end 1411 to the fourth free end 1412 of the fourth radiator 141 is used to support the second frequency band, that is, the fundamental mode of the entire branch of the fourth radiator 141 supports the second frequency band. Therefore, the fourth radiator 141 of the fourth antenna 140 has higher efficiency when supporting the second frequency band.

[0127] Since the fourth free end 1412 is opposite to and spaced from the second free end 1212 to form a second gap 330b, the second gap 330b is also referred to as defining the second free end 1212 and the fourth free end 1412. A quarter-wavelength mode from the fourth ground end 1411 to the fourth free end 1412 of the fourth radiator 141 supports the second frequency band, which is also referred to as a quarter-wavelength mode from the fourth ground end 1411 to the second gap 330b supports the second frequency band, or a quarter-wavelength mode from the second gap 330b to the fourth ground end 1411 supports the second frequency band, or a quarter-wavelength mode of the entire branch section of the fourth radiator 141 supports the second frequency band.

[0128] As described above, the quarter-wavelength mode from the second free end 1212 of the second radiator 121 to the second ground end 1211 supports the first frequency band. When the first frequency band includes a high frequency band, the quarter-wavelength mode from the fourth feed point P4 of the fourth radiator 141 to the fourth ground end 1411 is also used to support the first frequency band. The fourth free end 1412 is opposite to the second free end 1212 and is spaced apart to form a second gap 330b. Therefore, the fourth radiator 141 is coupled to the second radiator 121 through the second gap 330b. When the first frequency band includes a high frequency band, the fourth radiator 141 couples energy from the second radiator 121, and the fourth radiator 141 also supports the high frequency band. Therefore, when the first frequency band includes a high frequency band, not only can the second radiator 121 be used to support the first frequency band, but the part between the fourth feeding point P4 and the fourth ground end 1411 of the fourth radiator 141 can also be used to support the first frequency band, so that the antenna assembly 10 has better antenna performance in the first frequency band.

[0129] Furthermore, in one embodiment, a quarter-wavelength mode from the second free end 1212 of the second radiator 121 to the second ground end 1211 supports a third frequency band, and a three-quarter-wavelength mode from the fourth free end 1412 of the fourth radiator 141 to the fourth ground end 1411 supports a third frequency band.

[0130] As can be seen from the above description, the second radiator 121 of the second antenna 120 supports the first frequency band, and the second radiator 121 supports the third frequency band, so that the second antenna 120 can meet the communication requirements of the first frequency band and the third frequency band.

[0131] The quarter-wavelength mode from the second free end 1212 of the second radiator 121 to the second ground end 1211 supports the third frequency band. The "wavelength" in this context refers to the wavelength corresponding to the center frequency (or center frequency) of the third frequency band. A quarter-wavelength mode is also called a fundamental mode, and the frequency band supported by the fundamental mode generally has higher efficiency. The quarter-wavelength mode from the second free end 1212 of the second radiator 121 to the second ground end 1211 supports the third frequency band. Therefore, the second radiator 121 has higher efficiency when supporting the third frequency band.

[0132] The quarter-wavelength mode from the second free end 1212 of the second radiator 121 to the second ground end 1211 supports the third frequency band, which can also be called the quarter-wavelength mode from the second gap 330b to the second ground end 1211 supports the third frequency band, or the quarter-wavelength mode of the entire branch node of the second radiator 121 supports the third frequency band.

[0133] The three-quarter wavelength mode from the fourth free end 1412 of the fourth radiator 141 to the fourth ground end 1411 supports the third frequency band. The “wavelength” in this mode refers to the wavelength corresponding to the center frequency point (or center frequency) of the third frequency band.

[0134] When the antenna assembly 10 supports the third frequency band, it not only utilizes the quarter-wavelength mode from the second free end 1212 of the second radiator 121 to the second ground end 1211 to support the third frequency band, but also utilizes the three-quarter-wavelength mode from the fourth free end 1412 of the fourth radiator 141 to the fourth ground end 1411 to support the third frequency band, thereby enabling the antenna assembly 10 to have better communication performance in the third frequency band.

[0135] In one embodiment, the first frequency band includes a medium frequency band or a high frequency band, the second frequency band includes a low frequency band, and the third frequency band includes an N78 frequency band.

[0136] See also Figure 11 , Figure 11 This is a schematic diagram of an antenna assembly provided in another embodiment of the present application. The antenna assembly 10 also includes a fifth antenna 150 and a sixth antenna 160. Both the fifth antenna 150 and the sixth antenna 160 support the first frequency band. The first antenna 110, the second antenna 120, the fifth antenna 150, and the sixth antenna 160 constitute a 4x4 MIMO antenna for the first frequency band.

[0137] The antenna assembly 10 further includes the fifth antenna 150 and the sixth antenna 160, which can be incorporated into the antenna assembly 10 provided in any of the previous embodiments. For example, the antenna assembly 10 further includes the fifth antenna 150 and the sixth antenna 160, which can be incorporated into the antenna assembly 10 including the first antenna 110 and the second antenna 120; or, the antenna assembly 10 further includes the fifth antenna 150 and the sixth antenna 160, which can be incorporated into the antenna assembly 10 including the first antenna 110, the second antenna 120, and the fifth antenna 150; or, the antenna assembly 10 further includes the fifth antenna 150 and the sixth antenna 160, which can be incorporated into the antenna assembly 10 including the first antenna 110, the second antenna 120, the fifth antenna 150, and the sixth antenna 160. The schematic diagram of this embodiment should not be construed as limiting the antenna assembly 10 provided in the embodiments of this application.

[0138] MIMO stands for Multiple Input Multiple Output (MIMO). The first antenna 110, the second antenna 120, the fifth antenna 150, and the sixth antenna 160 constitute a 4*4 MIMO antenna in the first frequency band, which can significantly improve the system channel capacity and communication quality of the antenna assembly 10 in the first frequency band without increasing spectrum resources and antenna transmission power.

[0139] Please also refer to Figure 11 and Figure 12 , Figure 12 for Figure 11 The controller 20 is further configured to control, based on the posture of the electronic device 1, one of the first antenna 110, the second antenna 120, the fifth antenna 150, and the sixth antenna 160 to function as a transmitting antenna in a first frequency band, wherein the antenna performance of the one antenna supporting the first frequency band is superior to the antenna performance of the other three antennas supporting the first frequency band.

[0140] In this embodiment, the controller 20 is electrically connected to the first antenna 110, the second antenna 120, the fifth antenna 150 and the sixth antenna 160, respectively, to obtain the antenna performance of the first antenna 110, the antenna performance of the second antenna 120, the antenna performance of the fifth antenna 150 and the antenna performance of the sixth antenna 160, and compare them to determine which antenna among the first antenna 110, the second antenna 120, the fifth antenna 150 and the sixth antenna 160 has the best performance when supporting the first frequency band.

[0141] For example, when the antenna performance of the fifth antenna 150 supporting the first frequency band is better than the antenna performance of the first antenna 110 supporting the first frequency band, the antenna performance of the fifth antenna 150 supporting the first frequency band is better than the antenna performance of the second antenna 120 supporting the first frequency band, and the antenna performance of the fifth antenna 150 supporting the first frequency band is better than the antenna performance of the sixth antenna 160 supporting the first frequency band, the controller 20 controls the fifth antenna 150 to be a transmitting antenna supporting the first frequency band, and the first antenna 110, the second antenna 120, and the sixth antenna 160 to be receiving antennas supporting the first frequency band. In addition, the fifth antenna 150 can not only transmit signals in the first frequency band but also receive signals in the first frequency band. In other words, the fifth antenna 150 serves as the primary receiver antenna (PRX) for the first frequency band.

[0142] The antenna assembly 10 of the electronic device 1 provided in the embodiment of the present application, the controller 20 is also used to control one of the first antenna 110, the second antenna 120, the fifth antenna 150 and the sixth antenna 160 to be a transmitting antenna of the first frequency band according to the posture of the electronic device 1, wherein the antenna performance of the one when supporting the first frequency band is better than the antenna performance of the other three antennas when supporting the first frequency band, so that the antenna assembly 10 has better transmission performance when supporting 4*4 MIMO of the first frequency band.

[0143] Please see further Figure 11 The fifth antenna 150 includes a fifth radiator 151 and a first parasitic radiator 152. The fifth radiator 151 has a fifth ground terminal 1511, a fifth feed point P5, and a fifth free terminal 1512. The fifth ground terminal 1511 is grounded. Part of the fifth radiator 151 is located on the second side 1b, and the rest of the fifth radiator 151 is located on the third side 1c. The first parasitic radiator 152 is located on the second side 1b and includes a first parasitic ground terminal 1521 and a first parasitic free terminal 1522. The first parasitic ground terminal 1521 is grounded, and the first parasitic free terminal 1522 is opposite to and spaced from the fifth free terminal 1512 to form a third gap 320a. When the first frequency band includes an intermediate frequency band, the quarter-wavelength mode from the fifth ground terminal 1511 to the fifth free terminal 1512 of the fifth radiator 151 supports the first frequency band. When the first frequency band includes a high frequency band, the quarter-wavelength mode from the fifth feeding point P5 of the fifth radiator 151 to the fifth free end 1512 supports the first frequency band, and the quarter-wavelength mode of the entire branch of the first parasitic radiator 152 supports the first frequency band.

[0144] In this embodiment, the fifth antenna 150 further includes a fifth feed source S5 . The fifth feed source S5 is electrically connected to the fifth feeding point P5 to excite the fifth radiator 151 to support the first frequency band.

[0145] The fifth radiator 151 can be a laser direct structuring (LDS) radiator, or a flexible printed circuit (FPC) radiator, or a print direct structuring (PDS) radiator, or a metal branch radiator. When the antenna assembly 10 is applied to the electronic device 1, the fifth radiator 151 can be a mechanical design antenna (MDA) radiator designed using the metal insert of the electronic device 1 itself. For example, the fifth radiator 151 can be an antenna radiator designed using the middle frame 30 formed of plastic and metal of the electronic device 1. In addition, the fifth radiator 151 can also be a radiator of a metal frame antenna designed with a metal middle frame 30.

[0146] The fifth ground terminal 1511 is grounded, and may be, but is not limited to, electrically connected to the ground of the electronic device 1 via a conductive member (such as a connecting rib, a conductive spring, a conductive wire, or a conductive adhesive). The ground of the electronic device 1 includes, but is not limited to, at least one of the middle frame 30, the back cover 60, and the shielding of the display 50. In one embodiment, the fifth radiator 151 is a frame radiator formed using the metal middle frame 30 of the electronic device 1. The fifth ground terminal 1511 is electrically connected to the main body of the middle frame 30 via a connecting rib for grounding.

[0147] The first parasitic radiator 152 is a laser direct structuring (LDS) radiator, or a flexible printed circuit (FPC) radiator, or a print direct structuring (PDS) radiator, or a metal branch radiator. When the antenna assembly 10 is applied to the electronic device 1, the first parasitic radiator 152 can be a mechanical design antenna (MDA) radiator designed using the metal insert of the electronic device 1 itself. For example, the first parasitic radiator 152 can be an antenna radiator designed using the middle frame 30 formed of plastic and metal of the electronic device 1. In addition, the first parasitic radiator 152 can also be a radiator of a metal frame antenna designed using a metal middle frame 30.

[0148] In this embodiment, the fifth radiator 151 and the first parasitic radiator 152 are both formed on the frame of the middle frame 30 of the electronic device 1 as an example for illustration.

[0149] A fifth gap 330d is defined between the portion of the third frame 330 near the second frame 320 and the portion of the second frame 320 near the third frame 330 and the frame body 300. The second frame 320 has a third gap 320a. The third gap 320a is connected to the fifth gap 330d and extends through the end surface of the second frame 320 facing away from the frame body 300. The fifth gap 330d and the third gap 320a together define the fifth radiator 151.

[0150] Furthermore, a sixth gap 320b is formed between the second frame 320 and the frame body 300. The sixth gap 320b is connected to the fifth gap 330d, and the sixth gap 320b is connected to the third gap 320a. The sixth gap 320b and the third gap 320a together define the first parasitic radiator 152.

[0151] In an embodiment, the quarter-wavelength mode from the fifth ground end 1511 to the fifth free end 1512 of the fifth radiator 151 supports the “wavelength” of the first frequency band as the wavelength corresponding to the center frequency point (also called the center frequency) of the first frequency band.

[0152] The quarter-wavelength mode is also called the fundamental mode, and the frequency band supported by the fundamental mode generally has higher efficiency. In the electronic device 1 provided in the embodiment of the present application, the quarter-wavelength mode from the fifth ground end 1511 to the fifth free end 1512 of the fifth radiator 151 supports the first frequency band, that is, the fundamental mode of the fifth radiator 151 supports the first frequency band. Therefore, the fifth radiator 151 of the fifth antenna 150 has higher efficiency when supporting the first frequency band.

[0153] The first parasitic free end 1522 is opposite to the fifth free end 1512 and is spaced apart to form a third gap 320a. Therefore, when the first frequency band includes the intermediate frequency band, the quarter-wavelength mode from the fifth ground end 1511 to the fifth free end 1512 of the fifth radiator 151 supports the first frequency band. It can also be called the quarter-wavelength mode between the third gap 320a and the fifth ground end 1511 supports the first frequency band, or, it is called the quarter-wavelength mode of the entire branch of the fifth radiator 151 supports the first frequency band.

[0154] The quarter-wavelength mode of the entire branch of the first parasitic radiator 152 supports the first frequency band, and therefore, also referred to as the fundamental mode of the first parasitic radiator 152, supports the first frequency band. Therefore, the first parasitic radiator 152 of the fifth antenna 150 has high efficiency when supporting the first frequency band.

[0155] When the first frequency band includes a high-frequency band, the quarter-wavelength mode of the entire branch node of the first parasitic radiator 152 supports the first frequency band, which can also be called the quarter-wavelength mode from the third gap 320a to the first parasitic ground end 1521 supports the first frequency band, or the quarter-wavelength mode from the first parasitic ground end 1521 to the first parasitic free end 1522 of the first parasitic radiator 152 supports the first frequency band.

[0156] In this embodiment, when the first frequency band includes a high frequency, the fifth antenna 150 not only uses the fifth radiator 151 to support the first frequency band, but also uses the first parasitic radiator 152 to support the first frequency band, so that the fifth antenna 150 has better antenna performance in the first frequency band.

[0157] Please continue reading Figure 11 The electronic device 1 further includes a fourth side 1d, which is connected to the first side 1a and the third side 1c by a bend, and is disposed opposite the second side 1b. The sixth antenna 160 includes a sixth radiator 161 and a second parasitic radiator 162. The sixth radiator 161 is at least partially located on the fourth side 1d. The sixth radiator 161 includes a sixth ground terminal 1611, a sixth feeding point P6, and a sixth free terminal 1612. The sixth ground terminal 1611 is grounded. The second parasitic radiator 162 is at least partially located on the fourth side 1d. The second parasitic radiator 162 includes a second parasitic ground terminal 1621 and a second parasitic free terminal 1622. The second parasitic ground terminal 1621 is grounded. The second parasitic free terminal 1622 is opposite to the sixth free terminal 1612 and spaced apart to form a fourth gap 340b. When the first frequency band includes a medium frequency band, the quarter-wavelength mode from the sixth feed point P6 to the sixth free end 1612 supports the first frequency band. When the first frequency band includes a high frequency band, the quarter-wavelength mode from the sixth feed point P6 to the sixth free end 1612 supports the first frequency band, and the quarter-wavelength mode of the entire branch of the second parasitic radiator 162 supports the first frequency band.

[0158] In this embodiment, the sixth radiator 161 is partially located on the fourth side 1d and partially located on the first side 1a. In other embodiments, the sixth radiator 161 is located on the fourth side 1d.

[0159] In this embodiment, the second parasitic radiator 162 is partially located on the fourth side 1d and partially located on the third side 1c. In other embodiments, the second parasitic radiator 162 is located on the fourth side 1d.

[0160] In this embodiment, the sixth antenna 160 further includes a sixth feed source S6 . The sixth feed source S6 is electrically connected to the sixth feeding point P6 to excite the sixth radiator 161 to support the first frequency band.

[0161] The sixth radiator 161 can be a laser direct structuring (LDS) radiator, or a flexible printed circuit (FPC) radiator, or a print direct structuring (PDS) radiator, or a metal branch radiator. When the antenna assembly 10 is applied to the electronic device 1, the sixth radiator 161 can be a mechanical design antenna (MDA) radiator designed using the metal insert of the electronic device 1 itself. For example, the sixth radiator 161 can be an antenna radiator designed using the middle frame 30 formed of plastic and metal of the electronic device 1. In addition, the sixth radiator 161 can also be a radiator of a metal frame antenna designed with a metal middle frame 30.

[0162] The sixth ground terminal 1611 is grounded, and may be, but is not limited to, electrically connected to the ground of the electronic device 1 via a conductive member (such as a connecting rib, a conductive spring, a conductive wire, or a conductive adhesive). The ground of the electronic device 1 includes, but is not limited to, at least one of the middle frame 30, the back cover 60, and the shielding of the display 50. In one embodiment, the sixth radiator 161 is a frame radiator formed using the metal middle frame 30 of the electronic device 1. The sixth ground terminal 1611 is electrically connected to the main body of the middle frame 30 via a connecting rib for grounding.

[0163] The second parasitic radiator 162 is a laser direct structuring (LDS) radiator, or a flexible printed circuit (FPC) radiator, or a print direct structuring (PDS) radiator, or a metal branch radiator. When the antenna assembly 10 is applied to the electronic device 1, the second parasitic radiator 162 can be a mechanical design antenna (MDA) radiator designed using the metal insert of the electronic device 1 itself. For example, the second parasitic radiator 162 can be an antenna radiator designed using the middle frame 30 formed of plastic and metal of the electronic device 1. In addition, the second parasitic radiator 162 can also be a radiator of a metal frame antenna designed using a metal middle frame 30.

[0164] In this embodiment, the sixth radiator 161 and the second parasitic radiator 162 are both formed on the frame of the middle frame 30 of the electronic device 1 as an example for illustration.

[0165] In this embodiment, the middle frame 30 further includes a fourth side frame 340. The fourth side frame 340 is connected to the frame body 300. One end of the fourth side frame 340 is connected to one end of the first side frame 310 by a bend, and the other end of the fourth side frame 340 is connected to one end of the third side frame 330 by a bend. The fourth side frame 340 is disposed opposite to the second side frame 320.

[0166] In one embodiment, the side line of the fourth frame 340 away from the frame body 300 is the fourth side 1d; or the fourth frame 340 is disposed adjacent to the fourth side 1d.

[0167] In this embodiment, the sixth radiator 161 and the second parasitic radiator 162 are both formed on the frame of the middle frame 30 of the electronic device 1 as an example for illustration.

[0168] In this embodiment, a seventh gap 340a is defined between the portion of the fourth frame 340 near the first frame 310 and the portion of the first frame 310 near the fourth frame 340, and the frame body 300. The fourth frame 340 has a fourth gap 340b. The fourth gap 340b is connected to the seventh gap 340a and extends through the end surface of the fourth frame 340 facing away from the frame body 300. The seventh gap 340a and the fourth gap 340b together define the sixth radiator 161.

[0169] Furthermore, an eighth gap 340c is formed between the fourth frame 340 and the frame body 300. The eighth gap 340c is connected to the seventh gap 340a, and the eighth gap 340c is connected to the fourth gap 340b. The eighth gap 340c and the fourth gap 340b together define the second parasitic radiator 162.

[0170] In this embodiment, the quarter-wavelength mode from the sixth feeding point P6 to the sixth free end 1612 supports a wavelength of the first frequency band corresponding to the center frequency point (also called center frequency) of the first frequency band.

[0171] The quarter-wavelength mode is also called the fundamental mode, and the frequency band supported by the fundamental mode generally has a higher frequency. In the electronic device 1 provided in the embodiments of the present application, when the first frequency band includes an intermediate frequency band, the quarter-wavelength mode from the sixth feed point P6 to the sixth free end 1612 supports the first frequency band. That is, the fundamental mode of the sixth radiator 161 supports the first frequency band. Therefore, the sixth radiator 161 of the sixth antenna 160 has higher efficiency when supporting the first frequency band.

[0172] The second parasitic free end 1622 is opposite to the sixth free end 1612 and is spaced apart to form a fourth gap 340b. Therefore, when the first frequency band includes the intermediate frequency band, the quarter-wavelength mode from the sixth feeding point P6 to the sixth free end 1612 supports the first frequency band, which can also be called the quarter-wavelength mode from the sixth feeding point P6 of the sixth radiator 161 to the fourth gap 340b supports the first frequency band.

[0173] When the first frequency band includes a high frequency band, the quarter-wavelength mode of the entire branch of the second parasitic radiator 162 supports the first frequency band. Therefore, the fundamental mode of the second parasitic radiator 162 supports the first frequency band. Therefore, the second parasitic radiator 162 of the sixth antenna 160 has high efficiency when supporting the first frequency band.

[0174] When the first frequency band includes a high frequency band, the quarter-wavelength mode of the entire branch node of the second parasitic radiator 162 supports the first frequency band, which can also be called the quarter-wavelength mode from the fourth gap 340b to the first parasitic ground end 1521 supports the first frequency band, or the quarter-wavelength mode from the second parasitic ground end 1621 to the second parasitic free end 1622 of the second parasitic radiator 162 supports the first frequency band.

[0175] In this embodiment, when the first frequency band includes a high frequency, the sixth antenna 160 not only uses the sixth radiator 161 to support the first frequency band, but also uses the second parasitic radiator 162 to support the first frequency band, so that the sixth antenna 160 has better antenna performance in the first frequency band.

[0176] Please continue reading Figure 13 , Figure 13 This is a schematic diagram of an antenna assembly provided in yet another embodiment of the present application. The first antenna 110, the second antenna 120, and the fifth antenna 150 are all configured to support a third frequency band. The antenna assembly 10 also includes a seventh antenna 170. The seventh antenna 170 is configured to support the third frequency band. The first antenna 110, the second antenna 120, the fifth antenna 150, and the seventh antenna 170 constitute a 4x4 MIMO antenna for the third frequency band.

[0177] In this embodiment, the first antenna 110, the second antenna 120, the fifth antenna 150 and the seventh antenna 170 constitute a 4*4 MIMO antenna in the third frequency band, which can significantly improve the system channel capacity and communication quality of the antenna assembly 10 in the third frequency band without increasing spectrum resources and antenna transmission power.

[0178] In the schematic diagram of this embodiment, the antenna assembly 10 further includes the seventh antenna 170 and is incorporated into the antenna assembly 10 provided in the previous embodiment. This should be understood as not limiting the embodiments of this application. For example, in the schematic diagram of this embodiment, the antenna assembly 10 further includes the seventh antenna 170 and is incorporated into the antenna assembly 10 including the sixth antenna 160. This should be understood as not limiting the embodiments of this application. The antenna assembly 10 may also be incorporated into an antenna assembly 10 that does not include the sixth antenna 160.

[0179] In this embodiment, the seventh antenna 170 includes a seventh radiator 171 and a seventh feed S7. The seventh feed S7 is electrically connected to the seventh radiator 171 to stimulate the seventh radiator 171 to support the third frequency band. In this embodiment, the seventh radiator 171 is positioned corresponding to the second side 1b. Specifically, in this embodiment, the seventh radiator 171 is located on the second side frame 320.

[0180] Please also refer to Figure 13 and Figure 14 , Figure 14 for Figure 11The controller 20 is further configured to control, based on the posture of the electronic device 1, one of the first antenna 110, the second antenna 120, the fifth antenna 150, and the seventh antenna 170 to function as a transmitting antenna in a third frequency band, wherein the antenna performance of the one antenna supporting the first frequency band is superior to the antenna performance of the remaining three antennas supporting the third frequency band.

[0181] In this embodiment, the controller 20 is electrically connected to the first antenna 110, the second antenna 120, the fifth antenna 150 and the seventh antenna 170, respectively, to obtain the antenna performance of the first antenna 110, the antenna performance of the second antenna 120, the antenna performance of the fifth antenna 150 and the antenna performance of the seventh antenna 170, and compare them to determine which antenna among the first antenna 110, the second antenna 120, the fifth antenna 150 and the seventh antenna 170 has the best performance when supporting the third frequency band.

[0182] For example, when the antenna performance of the fifth antenna 150 supporting the third frequency band is better than the antenna performance of the first antenna 110 supporting the third frequency band, the antenna performance of the fifth antenna 150 supporting the third frequency band is better than the antenna performance of the second antenna 120 supporting the third frequency band, and the antenna performance of the fifth antenna 150 supporting the third frequency band is better than the antenna performance of the seventh antenna 170 supporting the third frequency band, the controller 20 controls the fifth antenna 150 to be a transmitting antenna supporting the third frequency band, and the first antenna 110, the second antenna 120, and the seventh antenna 170 to be receiving antennas supporting the third frequency band. In addition, the fifth antenna 150 can not only transmit signals in the third frequency band but also receive signals in the third frequency band. In other words, the fifth antenna 150 serves as the primary receiver antenna (PRX) for the third frequency band.

[0183] The antenna assembly 10 of the electronic device 1 provided in the embodiment of the present application, the controller 20 is also used to control one of the first antenna 110, the second antenna 120, the third antenna 130 and the fourth antenna 140 to be a transmitting antenna of the third frequency band according to the posture of the electronic device 1, wherein the antenna performance of the one when supporting the third frequency band is better than the antenna performance of the other three antennas when supporting the third frequency band, so that the antenna assembly 10 has better transmission performance when supporting 4*4 MIMO of the third frequency band.

[0184] See also Figure 15 , Figure 15This is a schematic diagram of an antenna assembly according to another embodiment of the present application. In this embodiment, the antenna assembly 10 includes a first antenna 110, a second antenna 120, a third antenna 130, a fourth antenna 140, a fifth antenna 150, a sixth antenna 160, and a seventh antenna 170. The first antenna 110, the second antenna 120, the third antenna 130, the fourth antenna 140, the fifth antenna 150, the sixth antenna 160, and the seventh antenna 170 are described above and are not further described here.

[0185] In combination with the electronic device 1 provided in any of the foregoing embodiments, the first frequency band includes a medium frequency band, a high frequency band, a WiFi 2.4G frequency band, or an N78 frequency band.

[0186] The first frequency band includes a medium frequency band, a high frequency band, a WiFi 2.4G band, or an N78 band, so that the antenna assembly 10 of the electronic device 1 can meet the communication requirements of the medium frequency band, the high frequency band, the WiFi 2.4G band, or the N78 band.

[0187] In one embodiment, please refer to Figure 2 and Figure 16 , Figure 16 This is a schematic diagram of an electronic device provided in another embodiment of the present application. The electronic device 1 further includes a button 70. Accordingly, the first frame 310 further includes a button hole 310d. The button 70 is accommodated in the button hole 310d. In one embodiment, the button hole 310d is located in the third radiator 131. In this embodiment, the button hole 310d extends through the exterior surface and the interior surface of the third radiator 131.

[0188] In this embodiment, the button hole 310d is located on the third radiator 131 and avoids the first gap 310b. That is, the first gap 310b avoids the button hole 310d and is closer to the second side 1b than the button hole 310d. When a user operates the button 70, the hand operating the button 70 can be less likely to obstruct the first gap 310b, thereby ensuring that the first antenna 110 has relatively good antenna performance when supporting the first frequency band.

[0189] In one embodiment, the second frequency band supported by the third antenna 130 has lower frequencies than the first frequency band supported by the first antenna 110, and the length of the third radiator 131 of the third antenna 130 is greater than the length of the first radiator 111 of the first antenna 110. The button hole 310d is located on the third radiator 131. When the size of the button hole 310d is constant, the first frame 310 still has relatively good structural strength at the location of the third radiator 131.

[0190] The button 70 of the electronic device 1 can be, but is not limited to, a power button or a volume button. In this embodiment, the electronic device 1 includes two buttons 70 as an example. It can be immediately understood that this should not be construed as limiting the embodiments of this application. In other embodiments, the electronic device 1 may also include one button 70, or a number of buttons 70 greater than or equal to two.

It should be understood that this should not be construed as limiting the embodiments of the present application. In other embodiments, the dimensions of the first radiator 111 and the second radiator 121 can be designed based on the first frequency band supported by the first antenna 110 and the second antenna 120.

[0196] See also Figure 18 , Figure 18 This is a schematic diagram comparing the performance of the second antenna in the antenna assembly of an electronic device provided in one embodiment of the present application in the mid-frequency band and the high-frequency band in free space and in the second horizontal screen state. Figure 18 In (a), the simulation is performed by taking the first frequency band as the intermediate frequency band as an example; Figure 18 In (b), the simulation is performed by taking the first frequency band as a high frequency band as an example. Figure 18 (a) is a schematic diagram showing a performance comparison of the second antenna 120 in the antenna assembly 10 of the electronic device 1 provided in one embodiment of the present application in the intermediate frequency band in free space and in the second horizontal state; Figure 18 (b) is a schematic diagram comparing the performance of the second antenna 120 in the antenna assembly 10 of the electronic device 1 provided in one embodiment of the present application in the high frequency band in free space and in the second horizontal screen state.

Figure 18 In (a), the red curve (curve ①) is the system total efficiency curve of the intermediate frequency band when the first frequency band supported by the second antenna 120 in free space is the intermediate frequency band; the green curve (curve ②) is the system radiation efficiency curve of the intermediate frequency band when the electronic device 1 is in the second horizontal screen state and the first frequency band supported by the second antenna 120 is the intermediate frequency band.

[0197] Depend on Figure 17 and Figure 18 It can be seen that compared to the case where the electronic device 1 is in free space, when the electronic device 1 is in landscape mode (the first landscape mode or the second landscape mode) and is held by two hands (such as a gaming scenario), the antenna performance attenuation is about 1dB when the first frequency band is a medium frequency band; when the electronic device 1 is in landscape mode (the first landscape mode or the second landscape mode) and is held by two hands (such as a gaming scenario), the antenna performance attenuation is about 2dB when the first frequency band is a high frequency band, and the antenna performance attenuation is relatively small. Generally speaking, in the related art, when the electronic device 1 is in portrait mode, the antenna is set at the top or bottom of the electronic device 1. In the related art, when the electronic device 1 is in landscape mode and held by two hands, the antenna performance attenuation is about 5dB compared to when the electronic device 1 is in a free state. Therefore, it can be seen that in the electronic device 1 provided in the embodiment of the present application, the first antenna 110 and the second antenna 120 are set at the waist of the electronic device 1. Compared to the case where the electronic device 1 is in free space, the performance degradation in the first frequency band when the electronic device 1 is in landscape mode and held by two hands is relatively small. The electronic device 1 provided in the embodiment of the present application still has good antenna performance in the first frequency band when it is in a landscape state and held by both hands.

[0198] In summary, in an electronic device 1 provided by one embodiment of the present application, the first radiator 111 of the first antenna 110 in the antenna assembly 10 of the electronic device 1 is located on the first side 1a, and the second radiator 121 of the second antenna 120 is located on the third side 1c. The first free end 1112 of the first radiator 111 faces away from the second side 1b compared to the first ground end 1111, and the second free end 1212 of the second radiator 121 faces away from the second side 1b compared to the second ground end 1211. Therefore, both the first antenna 110 and the second antenna 120 are positioned at the waist of the long side of the electronic device 1. The controller 20 controls the better-performing one of the first antenna 110 and the second antenna 120 to function as the transmitting antenna in the first frequency band based on the posture of the electronic device 1, thereby ensuring that the electronic device 1 has better communication performance in the first frequency band.

[0199] In one embodiment, the first frequency band includes a medium frequency band or a high frequency band. Therefore, the first antenna 110 and the second antenna 120 are also referred to as medium and high frequency antennas. In one embodiment, the first radiator 111 of the first antenna 110 and the second radiator 121 of the second antenna 120 are symmetrically or approximately symmetrically arranged. The first radiator 111 of the first antenna 110 is located at a position adjacent to the second side 1b on the first side 1a, with the first free end 1112 of the first radiator 111 facing away from the second side 1b relative to the first ground end 1111. The second radiator 121 of the second antenna 120 is located at a position adjacent to the second side 1b on the third side 1c, with the second free end 1212 of the second radiator 121 facing away from the second side 1b relative to the second ground end 1211. Therefore, the first radiator 111 of the first antenna 110 and the second radiator 121 of the second antenna 120 can be considered to be arranged at the waist of the electronic device 1. When the first radiator 111 and the second radiator 121 are formed symmetrically or approximately symmetrically on the frame 30 of the electronic device 1, such as when the first radiator 111 is located on the first frame 310 and the second radiator is located on the second frame 320, the first radiator 111 and the second radiator 121 can also be said to be symmetrically or approximately symmetrically arranged on the waist of the middle frame 30. Thus, the positioning of the first radiator 111 and the second radiator 121 can cleverly avoid the position where a user's finger (such as the index finger or middle finger) is grasped when the electronic device 1 is in landscape mode and held with two hands (such as in a gaming scenario), making it difficult for the finger to reach the first gap 310b corresponding to the first radiator 111 and the second gap 330b corresponding to the second radiator 121, thereby ensuring that the antenna assembly 10 of the electronic device 1 has stable transmission performance (also known as radiation performance) in the first frequency band, providing strong protection for the transmission of signals in the first frequency band when the electronic device 1 is in landscape mode and held with two hands (such as in a gaming scenario).

[0200] In this embodiment, the frequency range of the mid-high frequency band is generally 1710 MHz to 2690 MHz. It is understood that in one embodiment, the first frequency band includes the mid-frequency band, and the antenna assembly 10 includes the first antenna 110 and the second antenna 120, and the antenna assembly 10 can also be considered an antenna assembly 10 with dual mid-frequency bands. In another embodiment, the first frequency band includes the high frequency band, and the antenna assembly 10 includes the first antenna 110 and the second antenna 120, and the antenna assembly 10 can be considered an antenna assembly 10 with dual high frequency bands. Furthermore, in other embodiments, the first frequency band can also include the WiFi 2.4G band, and accordingly, the antenna assembly 10 is an antenna assembly 10 with dual WiFi 2.4G bands. In yet another embodiment, the first frequency band can also include the N78 band, and accordingly, the antenna assembly 10 is an antenna assembly 10 with dual N78 bands.

[0201] When the electronic device 1 is in landscape mode and is held by the user with both hands, for example, when the user is in landscape mode and holding the electronic device 1 with both hands to play games, the controller 20 intelligently switches the transmitting antenna of the first frequency band to the antenna with smaller attenuation corresponding to the human hand according to the specific state of the electronic device 1 in landscape mode (such as whether it is the first landscape state or the second landscape state), thereby reducing the impact caused by blocking the electronic device 1 when the human hand holds or touches the electronic device 1, allowing the user to obtain a better network communication experience in the actual gaming experience.

[0202] It can be understood that the scenarios in which the electronic device 1 is in landscape mode and is held by the user with both hands may be, but is not limited to, playing games, watching movies or videos, or watching live broadcasts, etc. The gaming scenarios described above and below are merely examples and should not be understood as limitations on this application.

[0203] In one embodiment, when the electronic device 1 is in the first landscape mode (when the electronic device 1 also includes a USB port, also referred to as with the USB port facing right) and is held by the user with both hands, the controller 20 switches the transmitting antenna in the first frequency band to the first antenna 110. That is, in the first landscape mode, the first antenna 110 serves as the primary transmitting antenna in the first frequency band. This allows for good radiation performance in the first frequency band and low human body attenuation in gaming scenarios in the first landscape mode.

[0204] In one embodiment, when the electronic device 1 is in the second landscape orientation (also referred to as the USB port facing left, if the electronic device 1 also includes a USB port) and is held in both hands by a user, the controller 20 switches the transmitting antenna in the first frequency band to the second antenna 120. That is, in the second landscape orientation, the second antenna 120 becomes the primary transmitting antenna in the first frequency band. This ensures good radiation performance in the first frequency band and low human body attenuation in gaming scenarios in the second landscape orientation.

[0205] It can be seen that the electronic device 1 provided in the embodiment of the present application, when the electronic device 1 is in the first horizontal screen state or the second horizontal screen state, the controller 20 uses the first antenna 110 and the second antenna 120 as the intelligent switching strategy on the main transmitting antenna of the first frequency band to smoothly realize the intelligent switching of the first horizontal screen state and the second horizontal screen state, thereby realizing the complementarity of the antenna performance in the first frequency band in the game scene in the horizontal screen state.

[0206] When the first frequency band includes a medium frequency band or a high frequency band, the electronic device 1 provided in the embodiment of the present application adopts a design of two medium and high frequency antennas (i.e., the first antenna 110 and the second antenna 120) located at the waist of the electronic device 1, which effectively solves the problem that when the user holds the electronic device 1 with both hands in the horizontal screen state (such as in the game scene), the human hand absorbs the performance of the first antenna 110 and the second antenna 120 supporting the first frequency band. It greatly improves the antenna radiation efficiency of the antenna assembly 10 in the first frequency band in this scene, and advantageously ensures the network communication experience in the medium and high frequency bands in the game scene, allowing users to enjoy a more stable and smooth network connection during the game, avoiding freezes, delays, etc. caused by the impact of antenna performance, and laying a solid foundation for high-quality gaming experience.

[0207] The above is part of the implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
