The conductive frame 10 may be the middle frame 40 in the electronic device 1, or may be a frame other than the middle frame 40, and only has to be conductive. In this embodiment and the following embodiments, the conductive frame 10 is taken as an example of the middle frame 40 in the electronic device 1, and it should be understood that the conductive frame is not limited to the electronic device 1 provided in this application.

The conductive frame 10 may be made of a conductive material, for example, but not limited to, at least one or more of copper, aluminum, magnesium, gold, silver, and the like, and the conductive frame 10 is made of a conductive material. It is understood that, in other embodiments, the conductive frame 10 may include a partially non-conductive material in addition to a conductive material, as long as the conductive frame 10 includes a conductive material. The shape of the frame body 110 may be, but is not limited to, a rectangular parallelepiped or a quasi-rectangular parallelepiped. The housing body 110 may constitute a ground of the electronic apparatus 1. When the components in the electronic device 1 need to be grounded, they may be electrically connected to the frame body 110. For example, when the radiator of each antenna in the electronic device 1 needs to be grounded, the radiator can be electrically connected to the frame body 110 for grounding. It is understood that the electronic device 1 further includes other ground poles, such as the ground pole of the circuit board 60 (see fig. 3), or the ground pole of the screen 50 (see fig. 14 and 15). When the conductive frame 10 is not the middle frame 40, the ground pole in the electronic device 1 further includes the middle frame 40. In the following embodiments, the conductive frame 10 is taken as the middle frame 40 for illustration.

The first frame 120 is connected to the periphery of the frame body 110, in the present embodiment, the first frame 120 is a frame located on the right side of the frame body 110, it can be understood that the position of the first frame 120 relative to the frame body 110 varies with the placing posture of the conductive frame 10, and the position of the first frame 120 relative to the frame body 110 in the schematic diagram of the present embodiment should not be understood as a limitation to the electronic device 1 provided in the present application.

In an embodiment, the first frame 120 protrudes from at least one of two opposite surfaces of the frame body 110 to cooperate with the frame body 110 to carry other components (such as the screen 50, the circuit board 60, etc.) in the electronic device 1. In another embodiment, the first frame 120 is flush with the frame body 110 and even lower than at least one of two opposite surfaces of the frame body 110. It is understood that the first frame 120 may be connected to the periphery of the frame body 110.

The second frame 130 is connected to the periphery of the frame body 110, in the present embodiment, the second frame 130 is a frame located at the lower side of the frame body 110, it can be understood that the position of the second frame 130 relative to the frame body 110 varies with the placing posture of the conductive frame 10, and the position of the second frame 130 relative to the frame body 110 in the schematic diagram of the present embodiment should not be understood as a limitation to the electronic device 1 provided in the present application.

In an embodiment, the second frame 130 protrudes from at least one of two opposite surfaces of the frame body 110 to cooperate with the frame body 110 to carry other components (such as the screen 50, the circuit board 60, etc.) in the electronic device 1. In another embodiment, the second frame 130 is flush with the frame body 110, even lower than at least one of two opposite surfaces of the frame body 110. It can be understood that the second frame 130 is only required to be connected to the periphery of the frame body 110.

The first frame 120 and the second frame 130 are connected in a bent manner, and the joint between the first frame 120 and the second frame 130 may be an arc, a right angle, an acute angle, an obtuse angle, or the like.

The length of the first frame 120 is greater than the length of the second frame 130, so that the first frame 120 is a long frame in the conductive frame 10, and the second frame 130 is a short frame in the conductive frame 10.

The first antenna 210 is a primary transmit antenna (PRX) and operates in a first frequency band. In the present embodiment, the first frequency Band is a low frequency Band (LB) as an example. The first antenna 210 may support low frequency bands of 2G, 3G, 4G, and 5G. I.e. the low frequency ranges from 703MHz to 960MHz, e.g. the B28 band, or the B20 band, or the B5 band, or the B8 band. When the first frequency band is a low frequency band, therefore, the required length of the first radiator 211 is long, and the first radiator 211 is disposed on the first frame 120 with the long length, thereby facilitating the layout of the first radiator 211.

In a classification manner, the first antenna 210 may be a Flexible Printed Circuit (FPC) antenna, a Laser Direct Structuring (LDS) antenna, a Print Direct Structuring (PDS) antenna, or a metal stub antenna. Accordingly, the first radiator 211 may be a flexible circuit board antenna radiator or a laser direct structuring antenna radiator, or a printed direct structuring antenna radiator, or a metal stub. The first radiator 211 may be disposed on the first frame 120, or may be directly formed on the first frame 120. When the first radiator 211 may be directly disposed on the first frame 120, the first radiator 211 may be a flexible circuit board antenna radiator, a laser direct structuring antenna radiator, a printed direct structuring antenna radiator, or a metal stub. When the first radiator 211 is directly formed on the first frame 120, the first radiator 211 may be a metal stub. For example, a gap may be formed on the first frame 120 to form a metal branch of the frame body 110 spaced by the gap, where the metal branch is the first radiator 211.

In another classification, the first Antenna 210 may be, but is not limited to, an Inverted-F Antenna (IFA), a Loop Antenna (Loop Antenna), or a Monopole Antenna (Monopole Antenna).

In this embodiment, one end of the first radiator 211 is located at one end of the first frame 120 away from the second frame 130, so that when the electronic device 1 is used, the one end of the first radiator 211 is not easily blocked by a hand of a user holding the electronic device 1, and performance degradation caused when the one end of the first radiator 211 is blocked by the hand is reduced. In addition, the first radiator 211 is disposed at a position that enables the electronic device 1 to be disposed near the head (for example, to receive a call), and the electromagnetic wave signal of the first frequency band transmitted and received by the first antenna 210 is not easily blocked by the head of the user. Therefore, in the electronic device 1 provided by the present application, the position of the first radiator 211 may improve the performance of the electronic device 1 when being held or disposed near the head, that is, the position of the first radiator 211 in the present application may enable the first antenna 210 to have better head-to-hand performance. Generally, when the first radiator 211 is disposed on the short side frame of the top, the first antenna 210 has a reduced performance of the head and hand (by 7-8 dB) when the electronic device 1 is held or disposed near the head of the user, compared to when the first radiator 211 is not shielded (which is equivalent to being disposed in free space); in contrast, in the electronic device 1 according to the embodiment of the present invention, compared with the case that the first radiator 211 is not shielded (which is equivalent to being disposed in a free space), when the electronic device 1 is held or disposed near the head of a user, the head-hand performance of the first antenna 210 is reduced by 2 to 3 dB. Therefore, the first radiator 211 in the electronic device 1 provided in the embodiment of the present application is disposed at a position that enables the first antenna 210 to have a good head-to-hand performance.

The second antenna 220 is a diversity receive antenna (DRX) and operates in a first frequency band. The second antenna 220 can support the first frequency band at the same time as the first antenna 210, or one of the second antenna 220 and the first antenna 210 operates under the control of a control signal at the same time. In this embodiment, the first frequency band is taken as a low frequency for example. The second antenna 220 may support low frequency bands of 2G, 3G, 4G, and 5G. I.e. the low frequency ranges from 703MHz to 960MHz, e.g. the B28 band, or the B20 band, or the B5 band, or the B8 band. When the first frequency band is a low frequency band, therefore, the required length of the second radiator 221 is long, one end of the second radiator 221 is located at the end of the first frame 120 departing from the first radiator 211, and the other end is located at the second frame 130, thereby facilitating the layout of the second radiator 221.

In a classification manner, the second antenna 220 may be a Flexible Printed Circuit (FPC) antenna, a Laser Direct Structuring (LDS) antenna, a Print Direct Structuring (PDS) antenna, or a metal stub antenna. Accordingly, the second radiator 221 may be a Flexible Printed Circuit (FPC) antenna radiator or a Laser Direct Structuring (LDS) antenna radiator, or a Print Direct Structuring (PDS) antenna radiator, or a metal stub. The second radiator 221 may be disposed on the second frame 130, or may be directly formed on the second frame 130. When the second radiator 221 may be directly disposed on the second frame 130, the second radiator 221 may be a flexible circuit board antenna radiator, a laser direct structuring antenna radiator, a printed direct structuring antenna radiator, or a metal stub. When the second radiator 221 is directly formed on the first frame 120 and the second frame 130, the second radiator 221 may be a metal branch. For example, a gap may be formed on the first frame 120 and the second frame 130 to form a metal branch of the frame body 110 spaced by the gap, where the metal branch is the second radiator 221.

In another classification, the second Antenna 220 may be, but is not limited to, an Inverted-F Antenna (IFA), a Loop Antenna (Loop Antenna), or a Monopole Antenna (Monopole Antenna).

In the electronic device 1 provided by the embodiment of the present invention, the first radiator 211 and the second radiator 221 are disposed at positions such that, in a free space, the performance of the second antenna 220 is higher (about 1.5dB higher) than that of the first antenna 210; the performance of the first antenna 210 is better than the performance of the second antenna 220 when the electronic device 1 is disposed adjacent to a head or the electronic device 1 is held. In other words, the first radiator 211 and the second radiator 221 are disposed at positions, and the second antenna 220 ensures low-frequency performance of free space; the first antenna 210 ensures performance when the electronic apparatus 1 is disposed adjacent to a head or the electronic apparatus 1 is held. To sum up, the electronic device 1 provided in the embodiment of the present application has better communication performance in the first frequency band when the electronic device 1 is disposed in the free space, near the head, or held by the first radiator 211 and the second radiator 221.

Due to the position of the second radiator 221, when the electronic device 1 is used in a portrait mode, the second radiator 221 is far from the head of the user, so that a test card (also referred to as a Tx white card) for performing electromagnetic Absorption Rate (SAR) performance detection on the performance of the electronic device 1 may be disposed adjacent to the second radiator 221, and the SAR value radiated by the user may be reduced. The electromagnetic wave energy absorption ratio can also be called specific absorption rate, and refers to the electromagnetic wave power absorbed or consumed by unit mass of human tissue, and the unit is W/Kg. The greater the SAR value is, the more electromagnetic wave power absorbed or consumed by the human tissue of unit mass is, the greater the harmfulness to the human body is; accordingly, the smaller the SAR value, the smaller the electromagnetic wave power absorbed or consumed per unit mass of human tissue, the less harmful to the human body.

Referring to fig. 4, fig. 4 is a schematic diagram of a first antenna in the electronic device provided in fig. 1. The first antenna 210 includes a first radiator 211, a plurality of first matching circuits 212, and a first switch 213. The first switch 213 is configured to switch the first matching circuit 212 electrically connected to the first radiator 211, so that the first antenna 210 supports a first sub-band, a second sub-band, a third sub-band, and a fourth sub-band in a first frequency band.

In this embodiment, the number of the first matching circuits 212 is 4, and the first switch 213 is a single-pole four-throw switch (SP4T), for example, but it can be understood that in other embodiments, the number of the first matching circuits 212 may be other, such as N, where N ≧ 2 and N is a positive integer, and accordingly, the first switch 213 is a single-pole N-throw switch.

The first switch 213 includes a common terminal 2131, N ports 2132, and a switch portion 2133, wherein the common terminal 2131 is electrically connected to the first radiator 211, each port 2132 of the N ports 2132 is electrically connected to a first matching circuit 212 and ground, and different ports 2132 are electrically connected to different first matching circuits 212. It should be noted that, the first matching circuits 212 in the plurality of first matching circuits 212 are different, and when the switch portion 2133 is electrically connected to the common port 2131 and one port 2132 of the N ports 2132, the first antenna 210 has different electrical lengths (i.e., different antenna apertures are switched), so as to implement the coverage of four frequency bands, i.e., a first sub-band, a second sub-band, a third sub-band, and a fourth sub-band. In this embodiment, the first sub-band is B28, the second sub-band is B20, the third sub-band is B5, and the fourth sub-band is B8. In other embodiments, the first sub-band, the second sub-band, the third sub-band and the fourth sub-band may be different sub-bands of low frequencies. It should be noted that the first antenna 210 can only support one frequency band of the first frequency sub-band, the second frequency sub-band, the third frequency sub-band and the fourth frequency sub-band at the same time, but cannot support two or even more frequency bands of the first frequency sub-band, the second frequency sub-band, the third frequency sub-band and the fourth frequency sub-band at the same time.

For the convenience of distinguishing the different ports 2132, the 4 ports 2132 are designated 213a, 213b, 213c, and 213d, respectively. In addition, in order to distinguish the different first matching circuits 212, the 4 first matching circuits are named as 212a, 212b, 212c, and 212d, respectively.

With continuing reference to fig. 1 and 2, and fig. 5 and 6, fig. 5 is a circuit block diagram of the electronic device provided in fig. 1; fig. 6 is a circuit block diagram of the first antenna shown in fig. 5. In this embodiment, the electronic device 1 further includes a controller 610. The controller 610 is electrically connected to the first antenna 210 and the second antenna 220, and the controller 610 is configured to use the second antenna 220 as a transmitting antenna for currently transmitting an electromagnetic wave signal of a first frequency band when the first antenna 210 has poor transmission performance.

The controller 610 may be disposed on the circuit board 60. Specifically, in this embodiment, the controller 610 determines the performance of the first antenna 210 according to a signal strength difference (RSSI) between the first antenna 210 and the second antenna 220 or a transmission power of the power amplifier 215(PA) of the first antenna 210. When the signal strength difference between the first antenna 210 and the second antenna 220 is smaller than a preset strength difference, or the power amplifier 215 is electrically connected to the first radiator 211 and the transmission power of the power amplifier 215 is greater than a preset power, it is determined that the performance of the first antenna 210 is not good. When the transmission performance of the controller 610 at the first antenna 210 is not good, the second antenna 220 is used as a transmission antenna for currently transmitting the electromagnetic wave signal of the first frequency band. In other words, the controller 610 switches the antenna for transmitting the electromagnetic wave signal of the first frequency band from the first antenna 210 to the second antenna 220. For example, the controller 610 may control a transmitting antenna of the electromagnetic wave signal of the first frequency band by controlling a switch 620 (DPDT). For example, when the controller 610 switches the radio frequency signal for transmitting the first frequency band to the first radiator 211 through the switch 620, the first antenna 210 serves as a transmitting antenna for currently transmitting the electromagnetic wave signal of the first frequency band. Wherein the rf signal for transmitting the first frequency band is generated by the rf front-end module 214.

It should be noted that the first antenna 210 includes a radio frequency front end module 214, a power amplifier 215, and a first radiator 211. The rf front-end module 214 is configured to output an rf signal. The input of the power amplifier 215 is electrically connected to the rf front-end module 214 for amplifying the rf signal. The first radiator 211 is electrically connected to the output end of the power amplifier 215, and is configured to receive the amplified radio frequency signal output by the power amplifier 215, convert the amplified radio frequency signal into an electromagnetic wave signal of the first frequency band, and radiate the electromagnetic wave signal. When the first antenna 210 is shielded, and the strength of the electromagnetic wave signal of the first frequency band radiated by the first radiator 211 is weak, the controller 610 controls the power amplifier 215 to increase the transmission power, and when the transmission power of the power amplifier 215 is greater than a preset power, it indicates that the first antenna 210 is shielded more. Then, when the power amplifier 215 is electrically connected to the first radiator 211 and the transmission power of the power amplifier 215 is greater than the preset power, the controller 610 controls the switch to electrically connect the rf front end module 214 to the second radiator 221, so as to use the second antenna 220 as a transmitting antenna for currently transmitting the electromagnetic wave signal in the first frequency band.

Referring to fig. 7, fig. 7 is a schematic view of a second antenna in an electronic device according to another embodiment of the present application. In this embodiment, the second antenna 220 further includes a first capacitor 222. The second antenna 220 further includes a capacitor, which can be incorporated into the electronic device 1 provided in any of the foregoing embodiments, and in the schematic diagram of the present embodiment, only the second antenna 220 further includes a first capacitor 222, which is incorporated into the schematic diagram of the foregoing embodiment as an example. One end of the first capacitor 222 is electrically connected to the second radiator 221, the other end of the first capacitor 222 is grounded, the first capacitor 222 is used for adjusting the resonant frequency point of the first frequency band supported by the second antenna 220, and the first capacitor 222 is used for making the second radiator 221 as an SAR detection radiator.

One end of the first capacitor 222 is electrically connected to the second radiator 221, and the other end of the first capacitor 222 is grounded, in other words, the second radiator 221 is designed to be suspended and grounded through the first capacitor 222. Therefore, the second radiator 221 also serves as an SAR detection radiator, thereby implementing multiplexing of the second antenna 220. In other words, the second antenna 220 may be used as a diversity receiving antenna operating in the first frequency band, and may also be used as a SAR detection antenna.

Optionally, in an embodiment, the capacitance value C1 of the first capacitor 222 satisfies: 22PF is less than or equal to C1 is less than or equal to 68 PF. The capacitance value C1 of the first capacitor 222 satisfies: c1 is not less than 22PF and not more than 68PF, so that on one hand, the resonant frequency point of the first frequency band supported by the second antenna 220 can be better adjusted, and on the other hand, the second radiator 221 can have a better detection effect when serving as an SAR detection radiator.

With continuing reference to fig. 1 and fig. 2, the conductive frame 10 further includes a third frame 140. The third frame 140 is disposed opposite to the first frame 120, the third frame 140 is connected to the second frame 130 in a bent manner, and both the third frame 140 and the first frame 120 are disposed on one side of the second frame 130. The antenna assembly 20 also includes a third antenna 230. The third antenna 230 operates in a second frequency band, a first frequency band, and a third frequency band, the third antenna 230 includes a third radiator 231, and the third radiator 231 is located at one end of the third frame 140 adjacent to the second frame 130.

The antenna assembly 20 further includes a third antenna 230 which can be incorporated into the electronic device 1 provided in any of the foregoing embodiments, and the electronic device 1 shown in the schematic diagram of the present embodiment should not be construed as limiting the electronic device 1 provided in the embodiments of the present application.

The third frame 140 is connected to the periphery of the frame body 110, in this embodiment, the third frame 140 is a frame located on the left side of the frame body 110, it can be understood that the position of the third frame 140 relative to the frame body 110 is different according to the placing posture of the conductive frame 10, and the position of the third frame 140 in the schematic diagram of this embodiment compared to the frame body 110 should not be understood as a limitation to the electronic device 1 provided in this application.

In this embodiment, the third frame 140 protrudes from at least one of two opposite surfaces of the frame body 110 to cooperate with the frame body 110 to carry other components in the electronic device 1. In another embodiment, the third rim 140 is flush with the frame body 110 and even lower than at least one of the two opposing surfaces of the frame body 110. It is understood that the third rim 140 is connected to the peripheral edge of the frame body 110.

The third frame 140 is connected to the second frame 130 in a bent manner, and the joint between the third frame 140 and the second frame 130 may be an arc, a right angle, an acute angle, an obtuse angle, or the like.

The length of the third frame 140 is greater than that of the second frame 130, and therefore, the third frame 140 is also a long frame in the conductive frame 10. The length of the third frame 140 may be equal to or unequal to the length of the first frame 120.

The third antenna 230 may support the first frequency band, the second frequency band, and the third frequency band at the same time. In an embodiment, the first frequency band is N28 in low frequency, the second frequency band may be GPS L5, and the third frequency band is WiFi 2.4G. It should be understood that the first frequency band, the second frequency band, and the third frequency band are only examples of three frequency bands supported by the third antenna 230, and should not be construed as limiting the third antenna 230.

The third radiator 231 is located at one end of the third frame 140 adjacent to the second frame 130, so that the performance of the second frequency band is better, and when the third antenna 230 operates in the second frequency band, the upper hemispherical radiation percentage can reach more than 80%. In addition, when the first frequency band that can be simultaneously supported by the third antenna 230 is N28 and the second frequency band is GPS L5, the electronic device 1 can meet the requirements of domestic GPS L5 and foreign GPS N28 in china. Therefore, the third antenna 230 can be designed to meet the common domestic and foreign requirements.

In another classification, the fourth Antenna 240 may be, but is not limited to, an Inverted-F Antenna (IFA), a Loop Antenna (Loop Antenna), or a Monopole Antenna (Monopole Antenna).

The fourth radiator 241 of the fourth antenna 240 is located at an end of the second frame 130 away from the first frame 120, so that when the electronic device 1 is used by a user, the end of the fourth radiator 241 is not easy to be held, and therefore, the environment of the fourth radiator 241 of the fourth antenna 240 is relatively good and can be used as a primary transmitting antenna (PRX) of a fourth frequency band. In an embodiment, the fourth frequency Band is a Medium High Band (MHB) frequency Band, and the range of the MHB frequency Band is: 1000MHz-3000 MHz.

In this embodiment, the fourth frame 150 protrudes from at least one of two opposite surfaces of the frame body 110 to cooperate with the frame body 110 to carry other components in the electronic device 1. In another embodiment, the fourth frame 150 is flush with the frame body 110, even lower than at least one of two opposite surfaces of the frame body 110.

The length of the fourth frame 150 is smaller than that of the first frame 110, and the length of the fourth frame 150 is smaller than that of the third frame 140, so that the fourth frame 150 is also a short frame in the conductive frame 10. The length of the fourth frame 150 may be equal to or different from the length of the second frame 130.

The fifth radiator 251 of the fifth antenna 250 is located at one end of the fourth frame 150, which is adjacent to the first frame 120, so that when the electronic device 1 is used by a user, the end of the fifth radiator 251 is not easy to be held, and therefore, the environment of the fifth radiator 251 of the fifth antenna 250 is relatively good, and the fifth radiator 251 can be used as a diversity receiving antenna of a fourth frequency band.

The fifth frequency Band is a High frequency (HB) Band and an Ultra High frequency (UHB) Band, and the ranges of the High frequency Band and the Ultra High frequency Band are as follows: 3000MHz-6000 MHz.

In a classification manner, the sixth antenna 260 may be a Flexible Printed Circuit (FPC) antenna, a Laser Direct Structuring (LDS) antenna, a Print Direct Structuring (PDS) antenna, or a metal stub antenna. Accordingly, the sixth radiator 261 may be a Flexible Printed Circuit (FPC) antenna radiator or a Laser Direct Structuring (LDS) antenna radiator, or a Print Direct Structuring (PDS) antenna radiator, or a metal stub.

In another classification, the sixth Antenna 260 may be, but is not limited to, an Inverted-F Antenna (IFA), a Loop Antenna (Loop Antenna), or a Monopole Antenna (Monopole Antenna).

The sixth radiator 261 is located at the first frame 120 and at an end of the first radiator 211 away from the second frame 130, so that when the electronic device 1 is used by a user, an end of the sixth radiator 261 is not easy to hold, and therefore, the environment of the sixth radiator 261 of the sixth antenna 260 is relatively good and can be used as a primary transmitting antenna (PRX) of a fourth frequency band.

In addition, when the electronic device 1 is held in the landscape state of the electronic device 1, the performance of the sixth antenna 260 is reduced, and therefore, the performance of the electronic device 1 in the landscape state (for example, landscape play) is improved.

In this embodiment, the sixth antenna 260 may simultaneously support the sixth frequency band in the fourth frequency band and the fifth frequency band at the same time.

In the schematic diagram of the present embodiment, the antenna assembly 20 includes the sixth antenna 260 as an example, and it is understood that in other embodiments, the antenna assembly 20 may not include the sixth antenna 260.

In another classification, the seventh Antenna 270 may be, but is not limited to, an Inverted-F Antenna (IFA), a Loop Antenna (Loop Antenna), or a Monopole Antenna (Monopole Antenna).

The seventh antenna 270 may support a sixth sub-band of the fourth band and the fifth band at the same time. The seventh antenna 270 is a diversity receiving antenna, and is configured by considering a distance between the seventh radiator 271 and the rear camera 810 (see fig. 2 and 3) in the electronic device 1 and a distance between the seventh radiator 271 and the rf module in the seventh antenna 270.

The seventh radiator 271 is generally disposed adjacent to the rear camera 810 of the electronic device 1, and therefore, the environment in which the seventh radiator 271 is located is relatively poor, which may affect the efficiency of the seventh antenna 270. In addition, the seventh radiator 271 is relatively far away from the rf module of the seventh antenna 270, and the loss on the trace between the seventh radiator 271 and the rf module of the seventh antenna 270 is relatively large, so that the antenna performance and board-level data transmission are relatively poor. Therefore, the seventh antenna 270 is set as a diversity receiving antenna for supporting the sixth sub-band of the fourth frequency band and the sixth frequency band, which is helpful to fully utilize the position of the electronic device 1, even the position of the electronic device 1 that is relatively unfriendly to the antenna environment, so that the electronic device 1 can set more antennas, and the electronic device 1 has better communication performance.

In addition, when the electronic device 1 is held in the landscape state of the electronic device 1, the performance of the seventh antenna 270 is less degraded, and therefore, the performance of the electronic device 1 in the landscape state (for example, landscape play) is better.

In the schematic diagram of the present embodiment, the antenna assembly 20 includes the seventh antenna 270 as an example, and it is understood that in other embodiments, the antenna assembly 20 may not include the seventh antenna 270.

The fourth antenna 240, the fifth antenna 250, the sixth antenna 260, and the seventh antenna 270 are used to form a 4 x 4MIMO antenna in the fourth frequency band, so that the antenna assembly 20 has better communication performance in the fourth frequency band.

Referring further to fig. 1 and 2, the antenna assembly 20 further includes an eighth antenna 280. The eighth antenna 280 is configured to support a sixth frequency sub-band of a sixth frequency band and a sixth frequency sub-band of a fifth frequency band, where the eighth antenna 280 includes an eighth radiator 281, and the eighth radiator 281 is located on the fourth border 150 and is located at an end of the fifth radiator 251 that is away from the first border 120.

The eighth radiator 281 is close to the proximity sensor 820 and the light sensor 830 (please refer to fig. 2 and fig. 3) in the electronic device 1, so that the eighth antenna 280 is configured to support an ultra-high frequency with low requirement on clearance, wherein the ultra-high frequency includes the WiFi 5G and N78. Therefore, the electronic device 1 provided by the embodiment of the present application can fully utilize the position of the electronic device 1, even the position of the electronic device 1 that is relatively unfriendly to the antenna environment, so that the electronic device 1 can be provided with more antennas, and the electronic device 1 has better communication performance.

In the schematic diagram of the present embodiment, the antenna assembly 20 includes the eighth antenna 280 as an example, and it is understood that in other embodiments, the antenna assembly 20 may not include the eighth antenna 280.

Since the fifth antenna 250, the sixth antenna 260, the seventh antenna 270, and the eighth antenna 280 all support the sixth sub-band, the fifth antenna 250, the sixth antenna 260, the seventh antenna 270, and the eighth antenna 280 may form a 4 × 4MIMO antenna of the sixth sub-band, so that the antenna assembly 20 has better communication performance in the sixth sub-band.

Furthermore, even if the fifth antenna 250, the sixth antenna 260, the seventh antenna 270, and the eighth antenna 280 do not form a 4 x 4MIMO antenna, since the fifth antenna 250, the sixth antenna 260, the seventh antenna 270, and the eighth antenna 280 can all support the sixth subband, antennas that are not blocked can still support the transmission of the electromagnetic wave signal of the sixth subband when the electronic device 1 is held in a plurality of postures, and the performance of the sixth subband when the electronic device 1 is held is maintained. That is, when the fifth antenna 250, the sixth antenna 260, the seventh antenna 270, and the eighth antenna 280 may implement 1T4R of the sixth sub-band.
