[0040] It should be understood that although the terms first, second, third, etc. may be used in the present disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0041] Figure 1 is a schematic structural diagram of an antenna structure according to an exemplary embodiment. Figure 1 As shown, the antenna structure includes a metal plate 10, a feed end, and a plurality of metal frame segments, and both ends of each metal frame segment are respectively connected to the metal plate 10 and surround a clearance with the metal plate 10, such as Figure 1 As shown in , the antenna structure includes a first frame segment 1 and a second frame segment 2, the first frame segment 1 and the metal plate 10 enclose a first clearance, the second frame segment 2 and the metal plate 10 enclose a second clearance, the second clearance is not connected to the first clearance, and each metal frame segment is provided with an antenna slit connected to the clearance, so that each metal frame segment can be divided into a plurality of sub-frame segments, each sub-frame segment can be used to radiate antenna signals, and a plurality of sub-frame segments belonging to the same metal frame segment can be used to radiate signals of the same frequency band or signals of different frequency bands. For example, the first frame segment 1 and the second frame segment 2 are respectively provided with a single slit, and the single slit divides the first frame segment 1 into a first upper sub-frame segment and a first lower frame segment, and the first upper sub-frame segment and the first lower frame segment can be used to radiate signals of the same frequency band or signals of different frequency bands. Similarly, the single slit divides the second frame segment 2 into a second upper sub-frame segment and a second lower sub-frame segment, and the second upper sub-frame segment and the second lower sub-frame segment can be used to radiate signals of the same frequency band or signals of different frequency bands.

[0042] Each metal frame segment can be connected to at least one feed end, based on which, a signal can be fed into the metal frame segment through the feed end, and combined with the setting of the antenna gap, the radiation of the antenna signal can be realized. Among them, the metal plate 10 can be set in a square shape, and at least four metal frame segments for radiating the first frequency band signal are connected to the top area of ​​the metal plate 10 to form a clearance. The top area of ​​the metal plate 10 can be understood as the area from the half position of the metal plate 10 to the end. Figure 1 The position shown in FIG. 1 is between the position shown by the dotted line and the top side of the metal plate 10 .

[0043] Based on this, at least four metal frame segments for radiating the first frequency band signal are connected to the top area of ​​the metal plate 10. When it is subsequently configured in an electronic device, the top area can be located on the top of the electronic device, thereby reducing the impact of hand-holding on the radiation performance of the first frequency band signal. At the same time, a large number of metal frame segments for radiating the first frequency band signal are beneficial to ensuring the radiation efficiency of the first frequency band signal.

[0044] Furthermore, at least three metal frame segments used to radiate the second frequency band signal are connected to the top area of ​​the metal plate 10 to form a clearance, and the metal frame segment used to radiate the first frequency band signal is different from the metal frame segment used to radiate the second frequency band signal. In other words, the same metal frame segment will not be used to radiate the first frequency band signal and the second frequency band signal at the same time. Based on this, when it is subsequently configured in an electronic device, the top area can be located at the top of the electronic device, so as to reduce the impact of hand-holding on the radiation performance of the second frequency band signal; furthermore, the radiation of the first frequency band signal and the second frequency band signal do not share the same metal frame segment, which is conducive to the same metal frame segment being used only to realize the radiation of a single frequency band signal, and is conducive to reducing the configuration of the combiner in the antenna structure, thereby achieving structural simplification. Among them, the first frequency band signal can include a 5G frequency band signal, such as an N77 frequency band signal and an N78 frequency band signal, and the second frequency band signal can be a medium-high frequency band signal, such as a 2G-4G frequency band signal. Among them, when the second frequency band signal is a medium or high frequency band signal, a separate break design is provided for the metal frame segment used to radiate the second frequency band signal, which is beneficial to expanding the radiation bandwidth of the metal frame segment, so that multiple adjacent frequency bands in the medium or high frequency band signals can be covered through the same resonance, thereby avoiding the use of a tuner for tuning, which is beneficial to simplifying the antenna structure and saving space.

[0045] Among them, at least one metal band used to radiate the first frequency band signal is only used to radiate the first frequency band signal, for example, the metal frame segment is only used to radiate the medium and high frequency band signals, so that the metal frame can use the intrinsic mode to radiate the signal to improve the radiation efficiency for the first frequency band signal. Similarly, at least one metal band used to radiate the second frequency band signal is only used to radiate the second frequency band signal, so that the metal frame can use the intrinsic mode to radiate the signal, for example, only used to radiate the 5G frequency band signal, so that the radiation efficiency for the second frequency band signal can be improved.

[0046] In some embodiments, Figure 1 As shown, the plurality of metal frame segments may further include a third frame segment 3, a fourth frame segment 4, a fifth frame segment 5, a sixth frame segment 6 and a seventh frame segment 7, and the third frame segment 3, the fourth frame segment 4, the fifth frame segment 5, the sixth frame segment 6 and the seventh frame segment 7 may all be connected to the metal plate 10 to enclose and form a corresponding clearance. The first frame segment 1, the second frame segment 2 and the third frame segment 3 are all located on the first side of the metal plate 10 in the width direction, that is, Figure 1 On the right side of the metal plate 10 , the second frame segment 2 is located between the first frame segment 1 and the third frame segment 3 .

[0047] The fourth frame segment 4 and the fifth frame segment 5 are both located on the top side of the metal plate 10, and the fourth frame segment 4 and the third frame segment 3 are connected to the same corner of the metal plate 10, that is, Figure 1 The fourth frame segment 4 and the third frame segment 3 are connected to the corner of the upper left corner of the metal plate 10, and the sixth frame segment 6 and the seventh frame segment 7 are located on the second side of the metal plate 10 in the width direction, and the second side is arranged opposite to the first side, that is, the sixth frame segment 6 and the seventh frame segment 7 are located Figure 1 The left side of the metal plate 10.

[0048] Among them, the first frame segment 1, the third frame segment 3, the fifth frame segment 5 and the sixth frame segment 6 are all used to radiate the second frequency band signal; the second frame segment 2, the fourth frame segment 4 and the seventh frame segment 7 are all used to radiate the first frequency band signal. Figure 1 The first frame segment 1, the second frame segment 2, the third frame segment 3, the fourth frame segment 4, the fifth frame segment 5, the sixth frame segment 6 and the seventh frame segment 7 are all located outside the top area of ​​the metal plate 10, which is beneficial to the influence of hand holding on the antenna efficiency when the subsequent antenna structure is configured in the electronic device. In addition, the first frame segment 1 and the third frame segment 3 are located on the first side of the metal plate 10, that is, Figure 1 The sixth frame segment 6 is located on the second side of the metal plate 10, that is, Figure 1 The left side of the metal plate 10 can prevent the horizontal screen from being stuck when the antenna structure is configured in the electronic device, so that communication can continue through the second frequency band signal; similarly, the second frame segment 2 is located on the first side of the metal plate 10, that is, Figure 1 The seventh frame segment 7 is located on the second side of the metal plate 10, that is, Figure 1The left side of the figure can prevent the screen from being stuck when held horizontally when the antenna structure is subsequently configured in the electronic device, so that communication can continue through the first frequency band signal.

[0049] Among them, the radiation power of the first frame segment 1, the fifth frame segment 5 and the sixth frame segment 6 are all less than or equal to the radiation power of the third frame segment 3, that is, the third frame segment 3 can be used as the main emitter of the second frequency band signal. Since the third frame segment 3 is close to the topmost area of ​​the metal plate 10 and is relatively farthest from the bottom of the metal plate 10, it is conducive to improving the user's one-handed operation experience. Similarly, the radiation power of the second frame segment 2 and the seventh frame segment 7 are all less than or equal to the radiation power of the fourth frame segment 4. Since the fourth frame segment 4 is located in the topmost area of ​​the metal plate 10 and is relatively farthest from the bottom of the metal plate 10, it is conducive to improving the user's one-handed operation experience.

[0050] Furthermore, the antenna structure also includes an eighth frame segment 8, which is partially located on the top side of the metal plate 10 and partially located on the second side of the metal plate 10, and the fifth frame segment 5 is located between the eighth frame segment 8 and the fourth frame segment 4. The eighth frame segment 8 can be used to radiate the third frequency band signal, thereby expanding the radiation frequency band of the antenna structure and enriching the communication scenarios of the electronic device configured with the antenna structure. The third frequency band signal may include a first sub-band signal and a second sub-band signal. The eighth frame segment 8 is connected to two feed ends, one of which is a first sub-band signal feed end, and the other is a second sub-band signal feed end. Compared with the single feed feeding solution, there is no need to design a combiner, which simplifies the structure.

[0051] For example, the third frequency band signal may include a WiFi frequency band signal, the first sub-frequency band signal may be a WiFi 2.4G frequency band signal, and the second sub-frequency band signal may be a WiFi 5G frequency band signal. Since the eighth frame segment 8 is located on the top side and the second side of the metal plate 10, and the sixth frame segment 6 is located on the second side of the metal plate 10, the eighth frame segment 8 is relatively close to the second side of the metal plate 10, and is relatively far away from the third frame segment 3 and the fourth frame segment 4 with larger radiation power, which is conducive to ensuring the conduction performance of the whole machine.

[0052] The sixth frame segment 6 is provided with a single antenna gap, which divides the sixth frame segment 6 into a first sub-frame segment 61 and a second sub-frame segment 62. The first sub-frame segment 61 is located between the seventh frame segment 7 and the second sub-frame segment 62, and the second sub-frame segment 62 is located between the eighth frame segment 8 and the first sub-frame segment 61. The first sub-frame segment 61 is used to radiate the second sub-frequency band signal, and the second sub-frame segment 62 is used to radiate the second frequency band signal and the first sub-frequency band signal. On the one hand, the third frequency band signal is radiated through multiple radiators, which is beneficial to improving the radiation efficiency of the third frequency band signal. On the other hand, the third frequency band signal is designed as a whole on the left side of the metal plate 10, relatively away from the main radiator of the medium and high frequency signals and the main radiator of the 5G frequency band signal, which can reduce the influence of the third frequency band signal on the medium and high frequency signals and the 5G frequency band signal.

[0053] Furthermore, the antenna structure also includes a ninth frame segment 9, which is partially located on the second side of the metal plate 10 and partially located on the bottom side of the metal plate 10. The ninth frame segment is used to radiate GPS low-frequency signals and first-frequency band signals, which is conducive to enriching the communication scenarios of electronic devices equipped with the antenna structure. Specifically, the ninth frame segment 9 is provided with a first break and a second break, and the second break divides the ninth frame segment 9 into a third sub-frame segment 91 and a fourth sub-frame segment 92, and the third sub-frame segment 91 is provided with a first break;

[0054] The third sub-frame segment 91 is partially located on the second side of the metal plate 10. Figure 1 The third sub-frame segment 91 is located on the right side and partially on the bottom side of the metal plate 10, and is used to radiate the L1 frequency band in the GPS low-frequency signal; the fourth sub-frame segment 92 is located on the bottom side of the metal plate 10, and the fourth sub-frame segment 92 is used to radiate the first frequency band signal, that is, the fourth sub-frame segment 92 can be used to radiate medium and high frequency signals; the first frame segment 1 is also used to radiate the L2 frequency band in the GPS low-frequency signal. In this way, the coverage of the L1 frequency band and the L2 frequency band in the GPS low-frequency signal is achieved to meet the domestic low-frequency communication needs. In some embodiments, the seventh frame segment 7 is also used to radiate the L3 frequency band in the GPS low-frequency signal, which can meet the international low-frequency communication needs. Of course, in some other embodiments, the seventh frame segment 7 is provided with a separate break to expand the bandwidth of the seventh frame segment 7, which is conducive to achieving the medium and high frequency signal coverage of the seventh frame segment 7 without configuring a tuning element.

[0055] For each of the above embodiments, it should be noted that Figure 1The arrows in represent a feed point connection respectively. In the aforementioned embodiment, the second frame segment 2, the fourth frame segment 4 and the fourth sub-frame segment 92 can be used and only used to radiate medium and high frequency signals, realize the separate design of medium and high frequency signals, and improve the radiation efficiency of medium and high frequency signals. In some cases, the seventh frame segment 7 can be compatible with medium and high frequency signals and L3 frequency bands. In other cases, the seventh frame segment 7 can also be used only to radiate medium and high frequency signals, which can be designed as needed.

[0056] The third frame segment 3 and the fifth frame segment 5 can be used only to radiate 5G band signals, the first frame segment 1 can be compatible with 5G band signals and L2 bands, and the second sub-frame segment 62 of the sixth frame segment 6 can be compatible with 5G band signals and WiFi 2.4G band signals. The first frame segment 1, the second frame segment 2, the third frame segment 3, the fourth frame segment 4, the fifth frame segment 5 and the seventh frame segment 7 in the aforementioned embodiment are all provided with a single or multiple antenna gaps, and are respectively connected to a single feed end.

[0057] Based on the antenna structure provided by the present disclosure, an electronic device is also provided. The electronic device may include the antenna structure described in any of the aforementioned embodiments. Multiple metal frame segments of the antenna structure may be enclosed to form the outer side of the middle frame of the electronic device. The metal plate 10 is the ground plate or supporting plate of the middle frame. Each antenna gap may be filled with non-conductive material to improve the structural strength of the middle frame.
