[0032] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described in the present application are only a part of the embodiments, not all of the embodiments. Based on the embodiments provided in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present application.

[0033] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it mutually exclusive, independent, or alternative to other embodiments. It can be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0034] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example: a component or device including one or more parts is not limited to the one or more parts listed, but optionally includes one or more parts that are not listed but inherent to the exemplified product, or one or more parts that it should have based on the described function.

[0035] An embodiment of the present application provides an electronic device 1. The electronic device 1 includes but is not limited to a mobile phone, a telephone, a television, a tablet computer (Pad), a personal computer, a laptop computer (Personal Computer, PC), a vehicle-mounted device, a headset, a watch, a wearable device, and other devices capable of transmitting and receiving electromagnetic wave signals. In the schematic diagram of the embodiment of the present application, the electronic device 1 is illustrated as a mobile phone as an example, which should be understood that it 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.

[0036] Please also read Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 A schematic diagram of an electronic device in a vertical screen state provided by an embodiment of the present application; Figure 2 for Figure 1 A schematic diagram of an electronic device shown in a horizontal screen state; Figure 3 For one embodiment Figure 1 A schematic diagram of a portion of the structure of an electronic device provided in; Figure 4 for Figure 3 Enlarged schematic diagram of point I in the middle. Figure 1 and Figure 2 The electronic device 1 shown in is a front view of the electronic device 1; Figure 3The electronic device 1 described in the figure is a back view of the electronic device 1. The electronic device 1 has a first side 1a and a second side 1b that are connected by bending. When the electronic device 1 is in a vertical screen state, the first side 1a is located at the top of the electronic device 1, and the length of the second side 1b is greater than the length of the first side 1a. The electronic device 1 also includes an antenna assembly 10. The antenna assembly 10 includes a first antenna 110. The first antenna 110 includes a first radiator 111, a first feed source S1, and a first coupled radiator 112. The first radiator 111 is arranged corresponding to the first side 1a, and the first radiator 111 has a first feeding point P1. The first feed source S1 is electrically connected to the first feeding point P1 to excite the first radiator 111 to support the first frequency band. The first coupled radiator 112 is spaced apart from the first radiator 111 and coupled to resonate in the first coupling frequency band.

[0037] In one embodiment, the first coupled radiator 112 resonates in the first coupled frequency band to improve the performance of the first frequency band supported by the first antenna 110. Specifically, if the first antenna 110 only includes the first radiator 111 and does not include the first coupled radiator 112, the performance in the first frequency band is weaker than the performance in the first frequency band when the first antenna 110 includes the first radiator 111 and the first coupled radiator 112. In other words, the performance of the first antenna 110 in the first frequency band when it includes the first radiator 111 and the first coupled radiator 112 is better than the performance of the first antenna 110 in the first frequency band when it includes only the first radiator 111 but does not include the first coupled radiator 112.

[0038] Therefore, when the electronic device 1 is in a horizontal state and is held: compared with the first antenna 110 that does not include the first coupled radiator 112 but only includes the first radiator 111, the first antenna 110 that includes the first radiator 111 and the first coupled radiator 112 has better performance in the first frequency band. Specifically, when the electronic device 1 is in a horizontal state and is held: the first feed source S1 excites the first radiator 111 to have a first performance in the first frequency band, and the first feed source S1 excites the first radiator 111 and the first coupled radiator 112 to have a second performance in the first frequency band, wherein the second performance is better than the first performance.

[0039] In this embodiment, the electronic device 1 has a first side 1a and a second side 1b that are connected by bending, and the length of the second side 1b is greater than the length of the first side 1a, so the first side 1a is the short side of the electronic device 1, and the second side 1b is the long side of the electronic device 1. When the electronic device 1 is in a vertical screen state, the first side 1a is located at the top of the electronic device 1, so when the electronic device 1 is in a vertical screen state, the first side 1a is also called the top side of the electronic device 1. Correspondingly, since the second side 1b is connected to the first side 1a by bending, when the electronic device 1 is in a vertical screen state, the second side 1b is located at the side of the electronic device 1, so the second side 1b is also called the side side of the electronic device 1.

[0040] The first radiator 111 is disposed corresponding to the first edge 1 a , including that the first radiator 111 is disposed adjacent to the first edge 1 a , or that a portion of the first radiator 111 is located at the first edge 1 a , which is not limited in this embodiment.

[0041] 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 an 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 metal frame radiator designed using a metal middle frame 30.

[0042] The first feed source S1 can be electrically connected to the first feeding point P1 through a feeding member. The feeding member can be, but is not limited to, a conductive screw, or a conductive glue, or a conductive spring, etc. The first feed source S1 is electrically connected to the first feeding point P1 to excite the first radiator 111 to support the first frequency band. The present application does not limit the resonance mode of the first feed source S1 to excite the first radiator 111, as long as the first feed source S1 can excite the first radiator 111 to support the first frequency band. The first frequency band can be, but is not limited to, a WiFi 2.4G frequency band or a WiFi 5G frequency band. In this embodiment, the first frequency band is taken as an example of the WiFi 2.4G frequency band.

[0043] The first coupled radiator 112 may be, but is not limited to, a flexible printed circuit (FPC) radiator, a print direct structuring (PDS) radiator, a laser direct structuring (LDS) radiator, or a metal branch radiator. The present application embodiment does not limit the material of the first coupled radiator 112.

[0044] The first coupling radiator 112 is spaced apart and coupled with the first radiator 111, so the first radiator 111 can couple part of its energy to the first coupling radiator 112. For the convenience of description, the frequency band supported by the resonance generated by the first coupling radiator 112 coupling the energy of the first radiator 111 is named as the first coupling frequency band. The relationship between the first coupling frequency band and the first frequency band will be described in detail later.

[0045] When the electronic device 1 is in the horizontal state and is held, the first radiator 111 is blocked. Therefore, compared with the electronic device 1 being in the free state, when the electronic device 1 is in the horizontal state and is held, the performance of the first radiator 111 is reduced. For the convenience of description, when the electronic device 1 is in the horizontal state and is held, the performance of the first radiator 111 stimulated by the first feed source S1 in the first frequency band is named as the first performance.

[0046] Since the first coupled radiator 112 is spaced apart and coupled with the first radiator 111, the first coupled radiator 112 resonates in the first coupled frequency band, and the performance of the first radiator 111 and the first coupled radiator 112 in the first frequency band stimulated by the first feed source S1 is named as the second performance. The second performance is better than the first performance. It can be seen that the first antenna 110 of the antenna assembly 10 provided in the embodiment of the present application includes the first coupled radiator 112, which can improve the antenna performance of the electronic device 1 in the first frequency band when it is in a horizontal screen state and is held.

[0047] It can be understood that the first performance and the second performance are both performance indicators of the same dimension when the first antenna 110 of the antenna assembly 10 supports the first frequency band, and the performance indicator can be the radiation efficiency; or the performance indicator is the reduction in radiation efficiency, or the performance indicator is the total system efficiency, etc. In this embodiment, the antenna performance of the first antenna 110 of the antenna assembly 10 in the first frequency band is taken as an example of the reduction in radiation efficiency, which can be understood that it should not be understood as a limitation on the embodiments of the present application. For example, when the electronic device 1 is in a horizontal screen state and is held, the second performance is better than the first performance, and the reduction in radiation efficiency in the first frequency band when the first antenna 110 includes the first coupled radiator 112 is less than the reduction in radiation efficiency in the first frequency band when the first antenna 110 does not include the first radiator 111.

[0048] In summary, in the electronic device 1 provided in the embodiment of the present application, the first antenna 110 in the antenna assembly 10 includes a first coupled radiator 112, and the first coupled radiator 112 is spaced apart and coupled with the first radiator 111 to resonate in the first coupled frequency band. When the electronic device 1 is in a horizontal state and is held: the first feed source S1 excites the first radiator 111 to have a first performance in the first frequency band, and the first feed source S1 excites the first radiator 111 and the first coupled radiator 112 to have a second performance in the first frequency band, wherein the second performance is better than the first performance. It can be seen that the first antenna 110 of the antenna assembly 10 provided in the embodiment of the present application includes the first coupled radiator 112, which can improve the antenna performance of the electronic device 1 in the first frequency band when it is in a horizontal state and is held.

[0049] Please read further Figure 3 and Figure 4 , the first radiator 111 extends along the direction of the first side 1a, and the first coupled radiator 112 extends along the direction of the first side 1a.

[0050] The first radiator 111 extends in the direction of the first side 1a, and the first coupled radiator 112 extends in the direction of the first side 1a, so the extending direction of the first coupled radiator is the same as the extending direction of the first radiator 111. In this way, when the first coupled radiator 112 is coupled with the first radiator 111, a resonant current supporting the first coupling frequency band can be better excited, thereby improving the antenna performance of the electronic device 1 in the first frequency band when it is in the horizontal screen state and held.

[0051] See also Figure 3 and Figure 4 , and please also refer to Figure 5 and Figure 6 , Figure 5 For another embodiment Figure 1 A schematic diagram of a portion of the structure of an electronic device provided in; Figure 6 for Figure 5 In the extension direction of the first side 1a, at least a portion of the first radiator 111 is opposite to at least a portion of the first coupled radiator 112 .

[0052] In the extension direction of the first side 1a, at least a portion of the first radiator 111 is opposite to at least a portion of the first coupling radiator 112, so that the excitation signal of the first radiator 111 can be better coupled to the first coupling radiator 112, and then when the first coupling radiator 112 is coupled with the first radiator 111, it can be better excited to support the resonant current of the first coupling frequency band, thereby improving the antenna performance of the electronic device 1 in the first frequency band when it is in the horizontal screen state and is held.

[0053] See also Figure 7 , Figure 7 for Figure 6 Detailed identification diagram of the structure shown in . In this embodiment, the first radiator 111 includes a first grounding end 1111 and a first free end 1112. The first grounding end 1111 is grounded. The first feeding point P1 is located between the first grounding end 1111 and the first free end 1112. The first coupled radiator 112 is located on one side of the first radiator 111. The first coupled radiator 112 has a first end 1121 and a second end 1122. The first end 1121 is closer to the second side 1b than the first grounding end 1111, and the second end 1122 is away from the second side 1b than the first free end 1112. In this way, all branches of the first radiator 111 are arranged corresponding to the first radiator 111. Therefore, the first coupling radiator 112 and the first radiator 111 can be better coupled, and when the first coupling radiator 112 and the first radiator 111 are coupled, they can be better excited to support the resonant current of the first coupling frequency band, thereby improving the antenna performance of the electronic device 1 in the first frequency band when it is in the horizontal screen state and is held.

[0054] Please read further Figure 5 and Figure 6In this embodiment, part of the first coupled radiator 112 is arranged to align with the first radiator 111. Specifically, the first radiator 111 also includes a first grounding end 1111 and a first free end 1112. The first grounding end 1111 is grounded. The first feeding point P1 is located between the first grounding end 1111 and the first free end 1112. The first radiator 111 is located on one side of the first radiator 111. The first coupled radiator 112 has a first end 1121 and a second end 1122. The first end 1121 is away from the second side 1b compared to the first grounding end 1111. The second end 1122 is arranged corresponding to the portion between the first grounding end 1111 and the first free end 1112.

[0055] The first ground terminal 1111 can be electrically connected to the ground electrode through a grounding member. The grounding member can be, but is not limited to, a conductive screw, a conductive glue, a conductive spring, or a conductive connecting rib. When the antenna assembly 10 is applied to an electronic device 1, the ground electrode can be, but is not limited to, a frame body 310 of a middle frame 30 of the electronic device 1, or a ground of a circuit board of the electronic device 1, or a shielding member of a display screen of the electronic device 1, or a conductive back cover of the electronic device 1.

[0056] As can be seen from the above description, the first radiator 111 includes a first grounding end 1111, a first feeding point P1 and a first free end 1112 which are arranged in sequence. The first coupled radiator 112 has a first end 1121 and a second end 1122. In the perspective of the figure, the first end 1121 is the end of the first coupled radiator 112 located on the right, and the second end 1122 is the end of the first coupled radiator 112 located on the left. The first end 1121 protrudes from the side of the first grounding end 1111 away from the first end 1121. In other words, the first end 1121 is further away from the second side 1b than the first grounding end 1111.

[0057] The second end 1122 is arranged corresponding to the portion between the first ground end 1111 and the first free end 1112. Therefore, the portion of the first coupled radiator 112 between the second end 1122 and the first end 1121 corresponding to the first radiator 111 is aligned with the first radiator 111. As a result, the first coupled radiator 112 and the first radiator 111 can be better coupled, and when the first coupled radiator 112 and the first radiator 111 are coupled, they can be better excited to support the resonant current of the first coupling frequency band, thereby improving the antenna performance of the electronic device 1 in the first frequency band when it is in a horizontal screen state and is held.

[0058] See also Figure 6 or Figure 7 , the distance d between the first coupling radiator 112 and the first radiator 111 satisfies: 1mm≤d≤10mm.

[0059] For example, the distance d between the first coupling radiator 112 and the first radiator 111 may be, but is not limited to, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm.

[0060] When the distance between the first coupled radiator 112 and the first radiator 111 is too small, the first coupled radiator 112 and the first radiator 111 are not easy to place; in addition, when the electronic device 1 is hit by an external force, the first coupled radiator 112 and the first radiator 111 are easily connected, resulting in failure of the first antenna 110. When the distance between the first coupled radiator 112 and the first radiator 111 is too large, the coupling effect of the first coupled radiator 112 coupling the energy of the first radiator 111 is not good, so that the first coupled radiator 112 has limited improvement on the performance of the first frequency band supported by the first radiator 111.

[0061] In the electronic device 1 provided in the embodiment of the present application, the distance d between the first coupled radiator 112 and the first radiator 111 satisfies: 1mm≤d≤10mm. On the one hand, the first coupled radiator 112 and the first radiator 111 can be easily arranged in the electronic device 1; on the other hand, the coupling effect between the first coupled radiator 112 and the first radiator 111 is better, and when the first coupled radiator 112 is coupled with the first radiator 111, they can be better excited to support the resonant current of the first coupling frequency band, thereby improving the antenna performance of the electronic device 1 in the first frequency band when it is in a horizontal screen state and held.

[0062] For further information, see Figure 5 and Figure 7 The first coupled radiator 112 has a first ground point G1. The first ground point G1 is electrically connected to the ground. The quarter-wavelength mode of the first coupled radiator 112 supports the first coupling frequency band.

[0063] It should be noted that the “wavelength” in the first coupling frequency band supported by the quarter-wavelength mode of the first coupling radiator 112 refers to the wavelength corresponding to the center frequency (also called the center frequency point) of the first coupling frequency band.

[0064] For the convenience of description, the first coupled radiator 112 is coupled to the first radiator 111 , and the resonant current generated is named as the first coupled resonant current. The first coupled resonant current is distributed in the entire branch of the first coupled radiator 112 .

[0065] For the convenience of description, the two ends of the first coupled radiator 112 are respectively named as the first end 1121 and the second end 1122. In other words, the first coupled radiator 112 has a first end 1121 and a second end 1122. The first end 1121 is closer to the second side 1b than the first ground end 1111. In this embodiment, the first ground point G1 is located at the second end 1122. In the current half-wavelength period shown in the figure, the first coupled resonant current flows from the first end 1121 to the second end 1122. It can be understood that the first coupled resonant current changes periodically, and in the next half-wavelength period, the first coupled resonant current flows from the second end 1122 to the first end 1121.

[0066] The quarter-wavelength mode is also called the fundamental mode. In this embodiment, the quarter-wavelength of the first coupled radiator 112 supports the first coupled frequency band. Therefore, when the first coupled radiator 112 supports the first coupled frequency band, the first antenna 110 has a higher radiation efficiency in the first coupled frequency band. Therefore, the antenna performance of the electronic device 1 in the first frequency band when it is in the horizontal screen state and held can be improved.

[0067] See also Figure 8 , Figure 8A schematic diagram comparing the efficiency of an electronic device in a first frequency band when it is in a horizontal screen state and held and the efficiency of an electronic device in a related art when it is in a horizontal screen state and held is provided for an embodiment of the present application. In this schematic diagram, the horizontal axis is the frequency, in GHz, and the vertical axis is the system radiation efficiency (System Radiation Efficiency), in dB. Among them, curve ① is a system radiation efficiency curve of an electronic device 1 in a first frequency band when it is in a horizontal screen state and held provided in an embodiment of the present application; curve ② is a system radiation efficiency curve of an electronic device 1 in a first state when it is in a horizontal screen state and held in a related art. The first antenna 110 of the antenna assembly 10 of the electronic device 1 provided in this embodiment includes a first coupled radiator 112, and the first antenna 110 of the electronic device 1 in the related art does not include the first coupled radiator 112. In this embodiment, taking the first frequency band as the WiFi 2.4G frequency band as an example, compared with the electronic device 1 in the related art, the system radiation efficiency of the electronic device 1 provided in the embodiment of the present application when it is in a horizontal screen state and held is improved by 4.2dB. It can be seen that the first antenna 110 of the electronic device 1 provided in the embodiment of the present application includes a first coupled radiator 112, so that the system efficiency in the first frequency band can be improved when the first antenna 110 is in a horizontal state and is held.

[0068] See also Fig. 9 and Fig.10 , Fig. 9 For another embodiment Figure 1 A schematic diagram of a portion of the structure of an electronic device provided in; Fig.10 for Fig. 9 An enlarged schematic diagram of point III in the figure. In this embodiment, the first coupled radiator 112 has a first connection point Q1. The first antenna 110 also includes a first tuning circuit 113. One end of the first tuning circuit 113 is electrically connected to the first connection point Q1, and the other end of the first tuning circuit 113 is grounded, and the first tuning circuit 113 includes an electrically connected first switch 1131 and a first tuning device 1132. The first switch 1131 has a first state and a second state, wherein the first state is one of the first switch 1131 being in an off state and a on state, and the second state is the other of the first switch 1131 being in an off state and a on state. When the electronic device 1 is in a free state: the first switch 1131 is in the first state, and the frequency of the first coupling frequency band is greater than the frequency of the first frequency band.

[0069] It should be noted that, in one embodiment, the so-called free state of the electronic device 1 may include but is not limited to the electronic device 1 being in a non-landscape holding state, or the electronic device 1 being in a non-held state.

[0070] When the electronic device 1 is in a non-landscape holding state, it includes but is not limited to: the electronic device 1 is in a landscape state and is not held, or the electronic device 1 is in a portrait state and is held, or the electronic device 1 is in an intermediate state and is held, etc. The so-called intermediate state refers to a state between the landscape state and the portrait state. When the electronic device 1 is in the intermediate state, it is also called that the electronic device 1 is in a tilted state.

[0071] When the electronic device 1 is in a non-held state, no matter the electronic device 1 is in a horizontal screen state, a vertical screen state, or an intermediate state, as long as the electronic device 1 is not held. For example, when the electronic device 1 is in a non-held state, it includes: the electronic device 1 is in a horizontal screen state and is not held, or the electronic device 1 is in a vertical screen state and is not held, or the electronic device 1 is in an intermediate state and is not held, etc.

[0072] When the first coupled radiator 112 has a first grounding point G1 and a first connection point Q1, the first connection point Q1 and the first grounding point G1 are at different positions, or the first connection point Q1 and the first grounding point G1 are at the same position, which is not limited in the present application. In the schematic diagram of this embodiment, the first connection point Q1 and the first grounding point G1 are at different positions for illustration.

[0073] The first tuning circuit 113 includes an electrically connected first switch 1131 and a first tuning device 1132. The first switch 1131 is connected in series with the first tuning device 1132, or the first switch 1131 is connected in parallel with the first tuning device 1132, etc. The electronic device 1 provided in the embodiment of the present application does not limit the connection relationship between the first switch 1131 and the first tuning device 1132. The first switch 1131 has two states, namely, an off state and an on state. When the first switch 1131 is in an off state or an on state, the electrical connection relationship between the first tuning device 1132 and the first connection point Q1 of the first coupled radiator 112 is different. For example, in one embodiment, when the first tuning device 1132 is connected in series with the first switch 1131, and the first tuning device 1132 is electrically connected to the first connection point Q1 through the first switch 1131, if the first switch 1131 is in the on state, the first tuning device 1132 is electrically connected to the first connection point Q1; if the first switch 1131 is in the off state, the first tuning device 1132 is electrically disconnected from the first connection point Q1.

[0074] In another embodiment, when the first tuning device 1132 is connected in parallel with the first switch 1131, one end of the first switch 1131 is electrically connected to the first connection point Q1, and the other end of the first switch 1131 is grounded. If the first switch 1131 is in an on state, the first tuning device 1132 is short-circuited, and the first connection point Q1 is directly electrically connected to the ground through the first switch 1131; if the first switch 1131 is in an off state, the first tuning device 1132 is electrically connected to the first connection point Q1.

[0075] In one embodiment, the first state is one of the first switch 1131 being in an off state and an on state, and the second state is the other of the first switch 1131 being in an off state and an on state, including: the first state is the first switch 1131 being in an off state, and the second state is the first switch 1131 being in an on state; or, the first state is the first switch 1131 being in an on state, and the second state is the first switch 1131 being in an off state.

When the electronic device 1 is in the free state: the first switch 1131 is in the first state, and the frequency of the first coupled frequency band is greater than the frequency of the first frequency band, so that the radiation efficiency of the electronic device 1 in the first frequency band when it is in the free state can be improved. Specifically, when the first switch 1131 is in the first state, the resonant current on the first radiator 111 (see the arrow on the first radiator 111) and the resonant current of the first coupled radiator 112 (see the arrow on the first coupled radiator 112) are in phase, so that the radiation efficiency of the electronic device 1 in the first frequency band when it is in the free state can be improved.

[0077] See also Fig.12 , Fig.12A schematic diagram comparing the efficiency of an electronic device in a free state in a first frequency band provided in an embodiment of the present application and the efficiency of an electronic device in a free state in the related art. In this schematic diagram, the horizontal axis is frequency, in GHz, and the vertical axis is system radiation efficiency (System Radiation Efficiency), in dB. In this embodiment, simulation is performed by taking the first frequency band as the WiFi 2.4G frequency band and the first coupling frequency band as the range of 2.5GHz to 2.6GHz as an example. Among them, curve ① is a system radiation efficiency curve of the electronic device 1 in a free state in the first frequency band provided in an embodiment of the present application; curve ② is a system radiation efficiency curve of the electronic device 1 in a free state in the related art. The first antenna 110 of the antenna assembly 10 of the electronic device 1 provided in this embodiment includes a first coupling radiator 112, while the first antenna 110 of the electronic device 1 in the related art does not include the first coupling radiator 112. The first coupling frequency band is generated by the first coupling radiator 112 coupling the energy of the first radiator 111, and the first coupling radiator 112 has an efficiency pit when supporting the first coupling frequency band (see Fig.12 At point "1" in the middle curve ①), the frequency of the first coupling frequency band is greater than the frequency of the first frequency band, which can avoid the decrease in radiation efficiency of the first frequency band caused by locating the efficiency pit in the first frequency band. The frequency of the first coupling frequency band is greater than the frequency of the first frequency band, so that the radiation efficiency of the electronic device 1 in the first frequency band when in a free state can be better improved.

[0078] Further, in this embodiment, when the electronic device 1 is in the horizontal screen state and is held: the first switch 1131 is in the second state, and the first coupling frequency band includes at least a part of the first frequency band.

[0079] When the electronic device 1 is in the horizontal screen state and is held, the first switch 1131 is in the second state, and the first coupling frequency band includes at least part of the first frequency band, which can improve the antenna performance of the electronic device 1 in the first frequency band when it is in the horizontal screen state and is held. Figure 8 In this embodiment, taking the first frequency band as the WiFi 2.4G frequency band as an example, compared with the electronic device 1 of the related art, the system radiation efficiency of the electronic device 1 provided in the embodiment of the present application is improved by 4.2dB when it is in the horizontal screen state and held. It can be seen that the first antenna 110 of the electronic device 1 provided in the embodiment of the present application includes the first coupled radiator 112, so that the system efficiency of the first antenna 110 in the first frequency band when it is in the horizontal screen state and held can be improved.

[0080] In one implementation, the first frequency band includes a WiFi 2.4G frequency band, and the first coupling frequency band ranges from 2.5 GHz to 2.6 GHz.

[0081] The first frequency band includes the WiFi 2.4G frequency band, and the first coupling frequency band ranges from 2.5 GHz to 2.6 GHz, which can better improve the radiation efficiency of the electronic device 1 in the WiFi 2.4G frequency band when it is in a free state.

[0082] In another embodiment, the first frequency band includes a WiFi 5G frequency band, and the frequency of the first coupling frequency band is greater than the frequency of the first frequency band, thereby being able to better improve the radiation efficiency of the electronic device 1 in a free state downloading the WiFi 5G frequency band.

[0083] See also Fig.13 and Fig.14 , Fig.13 A schematic diagram of an antenna assembly provided in another embodiment of the present application; Fig.14 for Fig.13 An enlarged schematic diagram at IV in FIG. In this embodiment, the electronic device 1 includes an antenna assembly 10, and the antenna assembly 10 includes a first antenna 110. Please refer to the previous description for the first antenna 110 of the antenna assembly 10, which will not be repeated here. In this embodiment, the antenna assembly 10 also includes a second antenna 120. The second antenna 120 includes a second radiator 121, a second feed source S2, and a second coupled radiator 122. At least a portion of the second radiator 121 is arranged corresponding to the first side 1a, and the second radiator 121 has a second feeding point P2. The second feed source S2 is electrically connected to the second feeding point P2 to excite the second radiator 121 to support the second frequency band. The second coupled radiator 122 is spaced apart from the second radiator 121 and coupled to resonate in the second coupling frequency band.

[0084] In one embodiment, the second coupling radiator 122 resonates in the second coupling frequency band to improve the performance of the second frequency band supported by the second antenna 120. Specifically, if the second antenna 120 only includes the second radiator 121 and does not include the second coupling radiator 122, the performance in the second frequency band is weaker than the performance in the second frequency band when the second antenna 120 includes the second radiator 121 and the second coupling radiator 122. In other words, the performance in the second frequency band when the second antenna 120 includes the second radiator 121 and the second coupling radiator 122 is better than the performance in the second frequency band when the second antenna 120 only includes the second radiator 121 but does not include the second coupling radiator 122.

[0085] Therefore, when the electronic device 1 is in a horizontal state and is held: compared with the second antenna 120 that does not include the second coupled radiator 122 but only includes the second radiator 121, the second antenna 120 that includes the second radiator 121 and the second coupled radiator 122 has better performance in the second frequency band. Specifically, when the electronic device 1 is in a horizontal state and is held: the second feed source S2 excites the second radiator 121 to have a third performance in the second frequency band, and the second feed source S2 excites the second radiator 121 and the second coupled radiator 122 to have a fourth performance in the second frequency band, wherein the fourth performance is better than the third performance.

[0086] 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 an 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 metal frame radiator designed using a metal middle frame 30.

[0087] At least part of the second radiator 121 is arranged corresponding to the first side 1a, including: part of the second radiator 121 is arranged corresponding to the first side 1a, and the other part of the second radiator 121 is arranged corresponding to the second side 1b; or, the second radiator 121 is arranged entirely corresponding to the first side 1a. In the schematic diagram of this embodiment, part of the second radiator 121 is arranged corresponding to the first side 1a, and the other part of the second radiator 121 is arranged corresponding to the second side 1b. It can be understood that this should not be understood as a limitation on the antenna assembly 10 provided in the embodiment of the present application.

[0088] The second feed source S2 can be electrically connected to the second feeding point P2 through a feeder. The feeder can be, but is not limited to, a conductive screw, a conductive glue, a conductive spring, etc. The second feed source S2 is electrically connected to the second feeding point P2 to excite the second radiator 121 to support the second frequency band. The present application does not limit the resonance mode of the second feed source S2 to excite the second radiator 121, as long as the second feed source S2 can excite the second radiator 121 to support the second frequency band. The second frequency band can be, but is not limited to, a WiFi2.4G frequency band or a WiFi 5G frequency band. In this embodiment, the second frequency band is taken as an example of a WiFi 5G frequency band.

[0089] The second coupled radiator 122 may be, but is not limited to, a flexible printed circuit (FPC) radiator, a print direct structuring (PDS) radiator, a laser direct structuring (LDS) radiator, or a metal branch radiator. The material of the second coupled radiator 122 is not limited in the present embodiment.

[0090] The second coupling radiator 122 is spaced apart and coupled with the second radiator 121, so the second radiator 121 can couple part of its energy to the second coupling radiator 122. For the convenience of description, the frequency band supported by the resonance generated by the second coupling radiator 122 coupling the energy of the second radiator 121 is named as the second coupling frequency band. The relationship between the second coupling frequency band and the second frequency band will be described in detail later.

[0091] In the schematic diagram of this embodiment, the second coupling radiator 122 is spaced apart from the first coupling radiator 112. In other words, the second coupling radiator 122 and the first coupling radiator 112 are separate structures. In other embodiments, the second coupling radiator 122 and the first coupling radiator 112 are an integral structure. The electronic device 1 provided in the present application does not limit whether the second coupling radiator 122 and the first coupling radiator 112 are separate structures or integral structures.

[0092] When the electronic device 1 is in the horizontal state and is held, the second radiator 121 is blocked. Therefore, compared with the electronic device 1 being in the free state, when the electronic device 1 is in the horizontal state and is held, the performance of the second radiator 121 is reduced. For the convenience of description, when the electronic device 1 is in the horizontal state and is held, the performance of the second radiator 121 stimulated by the second feed source S2 in the second frequency band is named as the third performance.

[0093] Since the second coupled radiator 122 is spaced apart and coupled with the second radiator 121, the second coupled radiator 122 resonates in the second coupled frequency band, and the performance of the second radiator 121 and the second coupled radiator 122 excited by the second feed source S2 in the second frequency band is named as the fourth performance. The fourth performance is better than the third performance. It can be seen that the second antenna 120 of the antenna assembly 10 provided in the embodiment of the present application includes the second coupled radiator 122, which can improve the antenna performance of the electronic device 1 in the second frequency band when it is in the horizontal screen state and is held.

[0094] It can be understood that the third performance and the fourth performance are both performance indicators of the same dimension when the second antenna 120 of the antenna assembly 10 supports the second frequency band, and the performance indicator can be the radiation efficiency; or the performance indicator is the reduction in radiation efficiency, or the performance indicator is the total system efficiency, etc. In this embodiment, the antenna performance of the second antenna 120 of the antenna assembly 10 in the second frequency band is taken as an example of the reduction in radiation efficiency, which can be understood that it should not be understood as a limitation on the embodiments of the present application. For example, when the electronic device 1 is in a horizontal screen state and is held, the fourth performance is better than the third performance, and the reduction in radiation efficiency in the second frequency band when the second antenna 120 includes the second coupled radiator 122 is less than the reduction in radiation efficiency in the second frequency band when the second antenna 120 does not include the second radiator 121.

[0095] In summary, in the electronic device 1 provided in the embodiment of the present application, the second antenna 120 in the antenna assembly 10 includes a second coupled radiator 122, and the second coupled radiator 122 is spaced apart and coupled with the second radiator 121 to resonate in the second coupled frequency band. When the electronic device 1 is in a horizontal state and is held: the second feed source S2 excites the second radiator 121 to have a third performance in the second frequency band, and the second feed source S2 excites the second radiator 121 and the second coupled radiator 122 to have a fourth performance in the second frequency band, wherein the fourth performance is better than the third performance. It can be seen that the second antenna 120 of the antenna assembly 10 provided in the embodiment of the present application includes a second coupled radiator 122, which can improve the antenna performance of the electronic device 1 in the second frequency band when it is in a horizontal state and is held.

[0096] Please read further Fig.13 and Fig.14 The second radiator 121 includes a first radiating portion 1211 and a second radiating portion 1212. The first radiating portion 1211 extends along the first side 1a. The second radiating portion 1212 is bent and connected to the first radiating portion 1211. The second radiating portion 1212 is arranged away from the first radiator 111 compared to the first radiating portion 1211, and the second radiating portion 1212 extends along the second side 1b. The second coupled radiator 122 is arranged adjacent to the first radiating portion 1211 and extends along the first side 1a.

[0097] In the electronic device 1 provided in the embodiment of the present application, the first radiating portion 1211 of the second radiator 121 extends along the first side 1a, the second coupled radiator 122 is arranged adjacent to the first radiating portion 1211, and the second coupled radiator 122 is arranged along the first side 1a. In this way, when the second coupled radiator 122 is coupled with the first radiator 111, a resonant current supporting the second coupling frequency band can be better excited, thereby improving the antenna performance of the electronic device 1 in the second frequency band when it is in a horizontal screen state and is held.

[0098] Please read further Fig.13 and Fig.14 The second coupled radiator 122 has a second ground point G2, and the second ground point G2 is electrically connected to the ground. The quarter-wavelength mode of the second coupled radiator 122 supports the second coupling frequency band.

[0099] It should be noted that the “wavelength” in the second coupling frequency band supported by the quarter-wavelength mode of the second coupling radiator 122 refers to the wavelength corresponding to the center frequency (also called the center frequency point) of the second coupling frequency band.

[0100] For the convenience of description, the second coupled radiator 122 is coupled to the second radiator 121 , and the resonant current generated is named as the second coupled resonant current. The second coupled resonant current is distributed in the entire branch of the second coupled radiator 122 .

[0101] For the convenience of description, the two ends of the second coupled radiator 122 are respectively named as the third end 1221 and the fourth end 1222. In other words, the second coupled radiator 122 has a third end 1221 and a fourth end 1222. The third end 1221 is closer to the second side 1b than the fourth end 1222. In this embodiment, the second grounding point G2 is located at the fourth end 1222. In the current half-wavelength period shown in the figure, the second coupled resonant current flows from the third end 1221 to the fourth end 1222. It can be understood that the second coupled resonant current changes periodically, and in the next half-wavelength period, the second coupled resonant current flows from the fourth end 1222 to the third end 1221.

[0102] The quarter-wavelength mode is also called the fundamental mode. In this embodiment, the quarter-wavelength of the second coupled radiator 122 supports the second coupled frequency band. Therefore, when the second coupled radiator 122 supports the second coupled frequency band, the second antenna 120 has a higher radiation efficiency in the second coupled frequency band. Therefore, the antenna performance of the electronic device 1 in the second frequency band when it is in the horizontal screen state and held can be improved.

The second coupled radiator 122 also has a second connection point Q2. The second antenna 120 also includes a second tuning circuit 123. One end of the second tuning circuit 123 is electrically connected to the second connection point Q2, and the other end of the second tuning circuit 123 is grounded. The second tuning circuit 123 includes an electrically connected second switch 1231 and a second tuning device 1232. The second switch 1231 has a third state and a fourth state. The third state is one of the disconnected state and the on state of the second switch 1231, and the fourth state is the other of the disconnected state and the on state of the second switch 1231. When the electronic device 1 is in a free state: the second switch 1231 is in the first state, and the frequency of the second coupling frequency band is greater than the frequency of the second frequency band.

[0104] When the second coupled radiator 122 has a second ground point G2 and a second connection point Q2, the second connection point Q2 and the second ground point G2 are at different positions, or the second connection point Q2 and the second ground point G2 are at the same position, which is not limited in the present application. In the schematic diagram of this embodiment, the second connection point Q2 and the second ground point G2 are at different positions for illustration.

[0105] The second tuning circuit 123 includes an electrically connected second switch 1231 and a second tuning device 1232. The second switch 1231 is connected in series with the second tuning device 1232, or the second switch 1231 is connected in parallel with the second tuning device 1232, etc. The electronic device 1 provided in the embodiment of the present application does not limit the connection relationship between the second switch 1231 and the second tuning device 1232. The second switch 1231 has two states, namely, an off state and an on state. When the second switch 1231 is in an off state or an on state, the electrical connection relationship between the second tuning device 1232 and the second connection point Q2 of the second coupled radiator 122 is different. For example, in one embodiment, when the second tuning device 1232 is connected in series with the second switch 1231, and the second tuning device 1232 is electrically connected to the second connection point Q2 through the second switch 1231, if the second switch 1231 is in the on state, the second tuning device 1232 is electrically connected to the second connection point Q2; if the second switch 1231 is in the off state, the second tuning device 1232 is electrically disconnected from the second connection point Q2.

[0106] In another embodiment, when the second tuning device 1232 is connected in parallel with the second switch 1231, one end of the second switch 1231 is electrically connected to the second connection point Q2, and the other end of the second switch 1231 is grounded. If the second switch 1231 is in an on state, the second tuning device 1232 is short-circuited, and the second connection point Q2 is directly electrically connected to the ground through the second switch 1231; if the second switch 1231 is in an off state, the second tuning device 1232 is electrically connected to the second connection point Q2.

[0107] In one embodiment, the third state is one of the second switch 1231 being in an off state and an on state, and the fourth state is the other of the second switch 1231 being in an off state and an on state, including: the third state is the second switch 1231 being in an off state, and the fourth state is the second switch 1231 being in an on state; or, the third state is the second switch 1231 being in an on state, and the fourth state is the second switch 1231 being in an off state.

[0108] When the electronic device 1 is in a free state: the second switch 1231 is in the third state, and the frequency of the second coupling frequency band is greater than the frequency of the second frequency band, so that the radiation efficiency of the electronic device 1 in the second frequency band when it is in a free state can be improved. Specifically, when the second switch 1231 is in the third state, the resonant current on the second radiator 121 is in phase with the resonant current of the second coupling radiator 122, so that the radiation efficiency of the electronic device 1 in the second frequency band when it is in a free state can be improved.

[0109] The second antenna 120 of the antenna assembly 10 of the electronic device 1 provided in this embodiment includes a second coupling radiator 122, while the second antenna 120 of the electronic device 1 in the related art does not include the second coupling radiator 122. The second coupling frequency band is generated by the second coupling radiator 122 coupling the energy of the second radiator 121. The second coupling radiator 122 has an efficiency pit when supporting the second coupling frequency band. The frequency of the second coupling frequency band is greater than the frequency of the second frequency band, which can avoid the decrease in radiation efficiency of the second frequency band caused by locating the efficiency pit in the second frequency band. The frequency of the second coupling frequency band is greater than the frequency of the second frequency band, so that the radiation efficiency of the electronic device 1 in the second frequency band when in a free state can be better improved.

[0110] Further, when the electronic device 1 is in the horizontal screen state and is held: the second switch 1231 is in the fourth state, and the second coupling frequency band includes at least a part of the second frequency band.

[0111] When the electronic device 1 is in the horizontal screen state and is held, the second switch 1231 is in the fourth state, and the second coupling frequency band includes at least part of the second frequency band, which can improve the antenna performance of the electronic device 1 in the second frequency band when it is in the horizontal screen state and is held. Figure 8 In this embodiment, taking the second frequency band as the WiFi 5G frequency band as an example, compared with the second antenna 120 of the electronic device 1 in the related art not including the second coupled radiator 122, the system radiation efficiency of the electronic device 1 provided in the embodiment of the present application is improved when it is in the horizontal screen state and is held. It can be seen that the second antenna 120 of the electronic device 1 provided in the embodiment of the present application includes the second coupled radiator 122, thereby improving the system efficiency of the second antenna 120 in the second frequency band when it is in the horizontal screen state and is held.

[0112] In one embodiment, the second frequency band includes a WiFi 5G frequency band. The second frequency band includes a WiFi 5G frequency band, so that the antenna assembly 10 can meet the communication requirements of the WiFi 5G frequency band. The electronic device 1 provided in the embodiment of the present application has good antenna performance in the WiFi 5G frequency band when it is in a horizontal screen state and is held.

[0113] See also Fig.17 and Fig.18 , Fig.17 A schematic diagram of an antenna assembly provided in yet another embodiment of the present application; Fig.18 for Fig.17 In this embodiment, the second coupled radiator 122 and the first coupled radiator 112 are an integrated structure.

[0114] The second coupled radiator 122 and the first coupled radiator 112 are an integrated structure, which can facilitate the layout of the first coupled radiator 112 , the second coupled radiator 122 , the first radiator 111 , and the second radiator 121 in the electronic device 1 .

[0115] Furthermore, when the second coupled radiator 122 and the first coupled radiator 112 are an integral structure, the first grounding point G1 of the first coupled radiator 112 and the second grounding point G2 of the second coupled radiator 122 are the same point. In this way, the structure of the second coupled radiator 122 and the first coupled radiator 112 as a whole electrically connected to the ground electrode is relatively simple, and can be grounded through the same grounding member.

[0116] It can be seen that in the electronic device 1 provided in the embodiment of the present application, when the second coupling radiator 122 and the first coupling radiator 112 are coupled radiators of an integrated structure, the coupled radiator can resonate in the first coupling resonance mode to support the first coupling frequency band to improve the performance of the first frequency band; and the coupled radiator can resonate in the second coupling resonance mode to support the second coupling frequency band to improve the performance of the second frequency band.

[0117] In combination with the electronic device 1 provided in any of the above embodiments, the first antenna 110 may support not only the first frequency band but also the third frequency band. In this way, the first antenna 110 may meet the communication requirements of the first frequency band and the third frequency band. For example, the first frequency band includes the WiFi 2.4G frequency band, and the third frequency band includes the GPS L1 frequency band. In this way, the first antenna 110 may meet the communication requirements of the WiFi 2.4G frequency band and the GPS L1 frequency band.

[0118] In one embodiment, when the antenna assembly 10 of the electronic device 1 further includes a second antenna 120, the second antenna 120 may support a fourth frequency band in addition to supporting the second frequency band. In this way, the second antenna 120 may meet the communication requirements of the second frequency band and the fourth frequency band. For example, the second frequency band includes a WiFi 5G frequency band, and the third frequency band includes an N78 frequency band. In this way, the second antenna 120 may meet the communication requirements of the WiFi 5G frequency band and the N78 frequency band.

[0119] For further information, see Fig.19 and Fig. 20 , Fig.19 A partial structural diagram of an electronic device provided in yet another embodiment of the present application; Fig. 20 for Fig.19 VII in the figure is an enlarged schematic diagram. In this embodiment, the antenna assembly 10 includes a first antenna 110 and a second antenna 120. Please refer to the previous description of the first antenna 110 and the second antenna 120, which will not be repeated here. Further, in this embodiment, the antenna assembly 10 also includes a third antenna 130 and a fourth antenna 140. In this embodiment, the antenna assembly 10 also includes a third antenna 130 and a fourth antenna 140 combined with the antenna assembly 10 provided in the previous embodiment is used as an example for illustration. It can be understood that it should not be understood as a limitation on the antenna assembly 10 provided in the embodiment of the present application. The third antenna 130 includes a third radiator 131 and a third feed source S3. The third radiator 131 and the second radiator 121 are an integral structure. The third radiator 131 has a third feeding point P3, and the third feed source S3 is electrically connected to the third feeding point P3 to excite the third radiator 131 to support at least one of the first frequency band, the fifth frequency band, and the sixth frequency band.
