[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] In the description of the embodiments of the present invention, it is necessary to understand that the orientation or positional relationship indicated by the term "thickness" etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than implying or indicating that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0020] See also Figure 1, is a schematic plan view showing a part of the internal structure of the electronic device 100 in one embodiment of the present application. Figure 1 As shown, the electronic device 100 includes a metal frame 10 and a plurality of radio frequency sources S1, the metal frame 10 is provided with a plurality of gaps 11, the plurality of gaps 11 separate the metal frame 10 into a plurality of independent frame segments 12, the plurality of frame segments 12 are used as antenna bodies and support frequency bands of a plurality of communication standards; wherein, among the plurality of frame segments, at least three frame segments support the 5G frequency band, and among the at least three frame segments supporting the 5G frequency band, at least one frame segment also supports the LMHB frequency band of LTE, and outside the at least three frame segments supporting the 5G frequency band, at least one frame segment supports the LMHB frequency band of LTE, and the at least one frame segment supporting the LMHB frequency band of LTE outside the at least three frame segments supporting the 5G frequency band and the at least three frame segments supporting the 5G frequency band are used to implement the 5G NSA communication standard; wherein, at least one frame segment supporting the LMHB frequency band of LTE outside the at least three frame segments supporting the 5G frequency band, and the frame segment of the LMHB frequency band that also supports LTE among the at least three frame segments supporting the 5G frequency band are located on different sides of the metal frame.
[0021] Therefore, in the present application, at least one frame segment simultaneously supports the LMHB frequency band of LTE, and at least one frame segment supporting the LMHB frequency band of LTE outside the at least three frame segments supporting the 5G frequency band and the at least three frame segments supporting the 5G frequency band are used to implement the 5G NSA communication standard, which can reduce the number of antenna bodies, and mainly implement the 5G NSA communication standard through the metal frame, thereby improving the antenna performance and reducing the cost. In addition, at least one frame segment supporting the LMHB frequency band of LTE outside the at least three frame segments supporting the 5G frequency band and the frame segment supporting the LMHB frequency band of LTE among the at least three frame segments supporting the 5G frequency band are located on different sides of the metal frame, respectively, ensuring that the antenna performance can be guaranteed when the user holds the device in different ways.
[0022] Among them, the frequency bands of communication standards supported by the multiple border segments 12 include 5G NSA (5th generation communication technology non-independent networking), 5G SA (5th generation communication technology independent networking), WIFI, GPS and 2 / 3 / 4G (2nd / 3rd / 4th generation communication technology) and other communication standards.
[0023] The aforementioned at least three frame segments support 5G frequency bands, which means that the at least three frame segments support frequency bands under 5G NSA and / or 5G SA communication standards. The LTE LMHB refers to low, medium and high frequencies under the 4G LTE communication standard.
[0024] Part of the frame segments 12 among the plurality of frame segments 12 are connected to the radio frequency source S1 , and at least one frame segment 12 is not connected to the radio frequency source S1 .
[0025] In the present application, by using multiple frame segments of the metal frame 10 as antenna bodies, frequency bands under multiple communication standards including 5G NSA, 5GSA, WIFI, GPS, and 2 / 3 / 4G can be supported, communication needs are met, and the number of antennas set inside the device can be minimized. In addition, some of the multiple frame segments 12 are connected to the RF source S1, and at least one frame segment 12 is not connected to the RF source S1. The frame segment 12 not connected to the RF source S1 is coupled with the adjacent frame segment 12 connected to the RF source S1. The reinforced antenna body or parasitic antenna body of the antenna body formed by the frame segment connected to the RF source can reduce the number of RF sources, improve antenna performance, or increase the antenna frequency band.
[0026] The frame segment 12 not connected to the RF source S1 is grounded, and is coupled with an adjacent frame segment 12 connected to the RF source S1 to serve as a reinforced antenna body or a parasitic antenna body of the antenna body formed by the frame segment connected to the RF source.
[0027] like Figure 1 As shown, the electronic device also includes a plurality of RF sources S1, wherein at least part of the frame segments 12 are connected to the RF sources S1, and the RF sources S1 are used to provide feeding signals to at least part of the frame segments, thereby stimulating the corresponding frame segments 12 to work, thereby realizing the transmission and reception of RF signals in various frequency bands under the above-mentioned multiple communication standards.
[0028] Among them, different RF sources S1 directly or indirectly excite the corresponding frame segments 12 to work, so that each frame segment 12 works in the corresponding frequency band under the corresponding communication standard. As mentioned above, a certain RF source S1 can directly excite only the directly connected frame segment 12 so that the frame segment 12 works to realize the transmission and reception of RF signals in the corresponding frequency band under the corresponding communication standard. For another example, another RF source S1 can directly excite the directly connected frame segment 12, and can also indirectly excite the frame segment adjacent to the directly connected frame segment 12 through coupled feeding excitation, so that the frame segment 12 and the adjacent frame segment work together to realize the transmission and reception of RF signals in the corresponding frequency band under the corresponding communication standard.
[0029] Among them, by coupling the frame segment 12 not connected to the RF source S1 with the adjacent frame segment 12 connected to the RF source S1, the antenna body formed by the frame segment connected to the RF source can be used as a reinforced antenna body or a parasitic antenna body, which can effectively improve the antenna performance or increase the antenna frequency band.
[0030] Among them, in this application, the word "connection" includes direct connection and indirect connection. For example, the connection between A and B includes the direct connection between A and B, and also includes the indirect connection between A and B through C.
[0031] Among them, at least all the frame segments 12 of the metal frame 10 and the plurality of radio frequency sources S1 constitute an antenna device 200 (such as Figure 8 As shown), that is, the antenna device 200 at least includes all the frame segments 12 of the above-mentioned metal frame 10 and the plurality of radio frequency sources S1.
[0032] like Figure 1 As shown, the electronic device 100 further includes a mainboard 20 , and the antenna device 200 further includes an antenna body 21 disposed on the mainboard 20 , and the antenna body 21 cooperates with a portion of the frame segment 12 to support a frequency band under one of the communication standards.
[0033] Among them, the antenna device 200 of the present application only needs to set one antenna body 21 on the mainboard 20 in addition to the antenna body formed by the frame segment of the metal frame 10, which can effectively improve the antenna performance compared with the existing solution that requires multiple antenna bodies 21 to be set on the mainboard 20. Among them, the antenna body 21 set on the mainboard 20 supports the high frequency band. Since the high frequency band has strong penetration, even if the antenna body 21 is located inside the electronic device 100, it will not have a significant impact on the radiation performance.
[0034] The antenna body 21 may be an LDS antenna formed on the antenna bracket of the mainboard 20 by laser technology, that is, an antenna bracket is provided on the mainboard 20, and then an LDS antenna is formed thereon. The LDS antenna refers to a metal antenna pattern directly plated on the antenna bracket provided on the mainboard 20 by laser technology. In other embodiments, the antenna body 21 may also be an FPC (flexible printed circuit) antenna provided on the mainboard 20. The FPC antenna refers to a metal antenna pattern formed on the FPC, and the FPC antenna may be fixed to the mainboard 20 by bonding, embedding, welding, etc.
[0035] In some embodiments, at least one of the multiple frame segments 12 independently supports a frequency band under a certain communication standard, and at least some of the frame segments 12 cooperate with at least other frame segments to support a frequency band under a certain communication standard.
[0036] Among them, the "at least part of the frame segments 12 cooperate with at least other frame segments to support a frequency band under a certain communication standard" includes: multiple frame segments 12 cooperate to support a frequency band under a certain communication standard, or multiple frame segments 12 cooperate with the antenna body 21 on the mainboard 20 to support a frequency band under a certain communication standard.
[0037] Among them, Figure 1 As shown, the antenna body 21 on the main board 20 is also connected to a radio frequency source S1. The antenna body 21 works under the excitation of the excitation signal of the radio frequency source S1, and works with other corresponding frame segments 12 to realize the reception and transmission of radio frequency signals of the corresponding frequency band under the corresponding communication standard.
[0038] like Figure 1 As shown, in some embodiments, at least one gap is opened at a portion of the metal frame 10 located at the bottom end D1 of the electronic device 100 .
[0039] The bottom end D1 of the electronic device 100 may be the end located at the bottom when the electronic device 100 is placed upright. The top end D2 of the electronic device 100 is generally provided with a camera, and the bottom end D1 is generally provided with a connection interface such as a USB interface. The bottom end D1 of the electronic device 100 may specifically be an end provided with a connection interface such as a USB interface. That is, in the present application, at least one gap 11 is provided on the frame of the metal frame 10 where the USB interface is provided.
[0040] Therefore, by opening at least one slit in the metal frame 10 at the bottom of the electronic device 100, the number of slits in the metal frame 10 at the bottom of the side of the electronic device 100 can be reduced, thereby reducing the impact caused by the user holding the electronic device during use.
[0041] Among them, Figure 1 As shown, the electronic device 100 is roughly square, and the metal frame 10 is a rectangular frame, including two opposite short frames 101 and two opposite long frames 102, and the two opposite short frames 101 and the two opposite long frames 102 together form the metal frame 10. Among them, the part of the metal frame 10 located at the bottom of the electronic device 100 can be specifically a part of one of the short frames 101 with a connection interface such as a USB interface.
[0042] The two short frames 101 include a first short frame 101a and a second short frame 101b, and the two long frames 102 include a first long frame 102a and a second long frame 102b. That is, the metal frame 10 includes a first short frame 101a and a second short frame 101b that are opposite to each other, and a first long frame 102a and a second long frame 102b that are opposite to each other. The first short frame 101a is located at the top of the electronic device 100, the second short frame 101b is located at the bottom of the electronic device 100, the first long frame 102a is located at the left side of the electronic device 100, and the second long frame 102b is located at the right side of the electronic device 100.
[0043] in, Figure 1 The schematic diagram is a diagram of viewing from one side of the screen of the electronic device 100. The directional terms "top", "bottom", "left side" and "right side" are all from the Figure 1 The viewing direction.
[0044] The second short frame 101b is provided with a connection interface such as a USB interface.
[0045] like Figure 1 As shown, in this embodiment, the first short frame 101a is provided with three slits 11a, 11b and 11c, the second short frame 101b is provided with a slit 11d, the first long frame 102a is provided with two slits 11e and 11f, and the second long frame 102b is provided with three slits 11g, 11h and 11i.
[0046] That is, in this embodiment, the metal frame 10 is provided with 9 slits 11, which divide the metal frame into nine independent frame segments 12. The independent frame segments 12 in this application refer to the frame segments 12 that are completely separated by the slits 11.
[0047] The slits 11a and 11c provided on the first short frame 101a are respectively close to the first long frame 102a and the second long frame 102b, and the slit 11b is located between the slits 11a and 11c and close to the slit 11a. The two slits 11e and 11f provided on the first long frame 102a are both provided close to the first short frame 101a, and the slit 11e is closer to the first short frame 101a than the slit 11f. The slit 11d provided on the second short frame 101b is provided close to the first long frame 102a, the slit 11g provided on the second long frame 102b is provided close to the first short frame 101a, and the slits 11h and 11i provided on the second long frame 102b are both provided close to the second short frame 101b, and the slit 11i is closer to the second short frame 101b than the slit 11h.
[0048] Therefore, the two slits 11e and 11f provided on the first long frame 102a on the metal frame 10 and the slit 11g provided on the second long frame 102b of the present application are all arranged close to the first short frame 101a, so no slit 11 is provided near the bottom of the left side of the electronic device 100. When the user holds the electronic device 100 vertically, the holding position is usually near the bottom of the side of the electronic device 100. Since the present application does not provide the slit 11 near the bottom of the left side, the impact of the user's holding on the antenna radiation will be reduced. Among them, in the present application, holding the electronic device 100 vertically refers to the way of holding the electronic device 100 when it is placed in a vertical screen display state, and correspondingly, holding the electronic device 100 horizontally refers to the way of holding the electronic device 100 when it is placed in a horizontal screen display state.
[0049] Specifically, the nine frame segments 12 include a first frame segment 12a located between the gaps 11b and 11c, a second frame segment 12b located between the gaps 11c and 11g, a third frame segment 12c located between the gaps 11g and 11h, a fourth frame segment 12d located between the gaps 11h and 11i, a fifth frame segment 12e located between the gaps 11i and 11d, a sixth frame segment 12f located between the gaps 11d and 11f, a seventh frame segment 12g located between the gaps 11f and 11e, an eighth frame segment 12h located between the gaps 11e and 11a, and a ninth frame segment 12i located between the gaps 11a and 11b.

[0051] That is, in this embodiment, the second frame segment 12 b is not connected to the RF source S1 , and the other frame segments 12 are each connected to a corresponding RF source S1 .
[0052] The non-end preset position B1 of the sixth frame segment 12f is grounded, and the sixth frame segment 12f is divided into two sub-frame segments 121f and 122f, wherein the sub-frame segment 121f is connected to the RF source S1, and the sub-frame segment 122f is grounded.
[0053] The preset position B0 of the non-end portion of the second frame segment 12b is grounded, and the preset position between the preset position B0 and one end of the second frame segment 12b adjacent to the third frame segment 12c is grounded. Thus, the second frame segment 12b has two grounding points.
[0054] Please also read Figure 2 , is a schematic plan view of each antenna body of the electronic device 100. In order to show it more clearly, Figure 2 Simplified, compared to Figure 1 Some components and numbers are omitted.

Therefore, in the present application, the multiple frame segments 12 actually form eight antenna bodies.
[0056] Specific, combined Figure 1 and Figure 2As shown, the third frame segment 12c is coupled with the second frame segment 12b, and the first antenna body ANT0 is formed between the third frame segment 12c and the grounded preset position B0 of the second frame segment 12b; the fifth frame segment 12e is coupled with the sub-frame segment 122f of the sixth frame segment 12f to form the second antenna body ANT1.

That is, the antenna body 21 located on the mainboard 20 constitutes the ninth antenna body ANT8, and in this application, a total of nine antenna bodies ANT0~ANT8 are actually formed.
[0058] Among them, when the first antenna body ANT0 is formed between the third frame segment 12c and the grounded preset position B0 of the second frame segment 12b, the portion between the grounded preset position B0 of the second frame segment 12b and the end adjacent to the third frame segment 12c serves as the parasitic antenna body of the third frame segment 12c, thereby increasing the antenna frequency band and realizing the frequency band supported by the first antenna body ANT0. When the third antenna body ANT2 is formed between the first frame segment 12a and the grounded preset position B0 of the second frame segment 12b, the portion between the grounded preset position B0 of the second frame segment 12b and the end adjacent to the first frame segment 12a serves as the reinforced antenna body of the first frame segment 12a, thereby improving the antenna performance and realizing the third antenna body ANT2 with stronger signal quality. When the fifth frame segment 12e is coupled with the sub-frame segment 122f of the sixth frame segment 12f to form the second antenna body, the sub-frame segment 122f of the sixth frame segment 12f serves as a reinforced antenna body of the fifth frame segment 12e, and increases the antenna frequency band, thereby realizing the frequency band supported by the second antenna body ANT1.
[0059] The frequency band supported by the first antenna body ANT0 is LMHB PRX, wherein in this application, LMHB refers to low, middle, and high bands, that is, the frequency band supported by the first antenna body ANT0 is low, middle, and high bands.

[0060] The frequency band supported by the second antenna body ANT1 is LMHB DRX+N41 DRX MIMO, wherein N41 refers to the N41 frequency band under the 5GNSA communication standard. That is, the frequency band supported by the first antenna body ANT0 is low, medium and high frequency + N41. Among them, LMHB DRX means that the second antenna body ANT1 defaults to a diversity antenna body of the low, medium and high frequency bands, and the N41 DRX MIMO means that the second antenna body ANT1 defaults to a diversity antenna body of the N41 frequency band, and supports a multiple input and output (middle high band, multiple input multiple output) antenna system under the N41 frequency band.
[0061] In some embodiments, at least one frame segment 12 supporting the LMHB frequency band of LTE other than the aforementioned at least three frame segments 12 supporting the 5G frequency band refers to the frame segment 12 constituting the first antenna body ANT0, and the frame segment 12 supporting the LMHB frequency band of LTE among the aforementioned at least three frame segments 12 supporting the 5G frequency band refers to the frame segment 12 constituting the second antenna body ANT1.

[0065] The frequency band supported by the sixth antenna body ANT5 is: N78 / N79 / N77 PRX, that is, the frequency band supported by the fourth antenna body ANT3 is the N78 / N79 / N77 frequency band, and the sixth antenna body ANT5 is the main antenna body of the N78 / N79 / N77 frequency band by default.
[0066] The frequency band supported by the seventh antenna body ANT6 is: GPS L1+WIFI2.4G / 5G, that is, the frequency band supported by the seventh antenna body ANT6 is GPS L1 band+WIFI 2.4G / 5G band.
[0067] Among them, the frequency of GPS L1 is 1575MHz, the frequency band range of WIFI 2.4G is 2.4-2.484MHz, and the frequency band range of WIFI 5G is 5.15-5.85MHz.
[0068] The frequency bands supported by the eighth antenna body ANT7 are: GPS L5+WIFI 5G+WIFI2.4G, that is, the frequency bands supported by the eighth antenna body ANT7 are GPS L5 frequency band+WIFI 2.4G frequency band+WIFI 5G frequency band.
[0069] Among them, the antenna body 21 located on the main board 20 constitutes the ninth antenna body ANT8, and supports the frequency band N78 / N79 / N77DRX MIMO, that is, the frequency band supported by the antenna body 21 located on the main board 20 is the N78 / N79 / N77 frequency band under the 5G NSA communication standard, and the default is the diversity antenna of the N78 / N79 / N77 frequency band, and supports the multi-input and output antenna system under the N78 / N79 / N77 frequency band.
[0070] Among them, since the N78 / N79 / N77 frequency band is a high frequency band, the antenna space requirement is relatively low, and setting the antenna body 21 on the bracket of the mainboard 20 can also better achieve the N78 / N79 / N77 antenna performance.
[0071] Therefore, the present application implements multiple frequency bands including 5G NSA, 5G SA, WIFI, GPS and 2 / 3 / 4G through a total of nine antenna bodies supporting frequency bands.
[0072] Among them, as mentioned above, the frequency band supported by the first antenna body ANT0 is the LMHB PRX frequency band, and the frequency band supported by the second antenna body ANT1 is LMHB DRX+N41 DRX MIMO; therefore, the first antenna body ANT0 and the second antenna body ANT1 both independently support 2 / 3 / 4G communication standards, that is, they can work independently in the 2 / 3 / 4G communication standards to realize the transmission and reception of radio frequency signals of the 2 / 3 / 4G communication standards.
[0073] As mentioned above, the frequency band supported by the seventh antenna body ANT6 is: GPS L1+WIFI2.4G / 5G, and the frequency band supported by the eighth antenna body ANT7 is: ANT8: GPS L5+WIFI 5G +WIFI2.4G.

[0074] In this embodiment, 5G NSA is specifically supported by 5 antenna bodies, and at least one of the 5 antenna bodies supports both LTE and 5G frequency bands. That is, the antenna architecture of 5G NSA includes the above-mentioned 5 antenna bodies, and at least one of the 5 antenna bodies supports both LTE and 5G frequency bands and supports frequency bands under dual communication standards.
[0075] Therefore, compared with the existing 5G NSA communication standard that requires six antennas, the present application can reduce one antenna body, which is more conducive to the overall layout of the antenna, and can also reduce the number of antennas on the mainboard 20, thereby reducing costs and improving the overall performance of the antenna.

In order to clearly illustrate the antenna architecture composition of the N41 frequency band of 5G NSA, Figure 3 Simplified, compared to Figure 1 Some components are omitted.
[0077] Specifically, the N41 frequency band of 5G NSA is supported by the first antenna body ANT0, the second antenna body ANT1, the third antenna body ANT2, the fourth antenna body ANT3 and the fifth antenna body ANT4. That is, the antenna architecture of the N41 frequency band of 5G NSA includes the first antenna body ANT0, the first antenna body ANT1, the third antenna body ANT2, the fourth antenna body ANT3 and the fifth antenna body ANT4. In this embodiment, the second antenna body ANT1 at least supports the frequency bands under the dual communication standards of LTE and N41 and can replace the existing two antenna bodies, the first antenna body ANT0 supports the LTE frequency band, the third antenna body ANT2, the fourth antenna body ANT3 and the fifth antenna body ANT4 all support the N41 frequency band, so that two antenna bodies supporting the LTE frequency band and four antenna bodies supporting the N41 frequency band are realized through five antenna bodies, and the RF signal reception and transmission of the N41 frequency band of 5G NSA can be realized.

In order to show it more clearly, Figure 4 The same simplification is also carried out. Figure 1 Some components are omitted.
[0081] Specifically, the N78 / N79 / N77 frequency band of 5G NSA is supported by the third antenna body ANT2, the fourth antenna body ANT3, the fifth antenna body ANT4, the sixth antenna body ANT5 and the ninth antenna body ANT8 (i.e., the antenna body 21 located on the mainboard 20). That is, the antenna architecture of the N78 / N79 / N77 frequency band of 5G NSA includes the third antenna body ANT2, the fourth antenna body ANT3, the fifth antenna body ANT4, the sixth antenna body ANT5 and the ninth antenna body ANT8.

The frequency band supported by the fourth antenna body ANT3 is MHB DRX+N41 MIMO2, thereby supporting the LTE frequency band. The fifth antenna body ANT4, the sixth antenna body ANT5 and the ninth antenna body ANT8 all support the N78 / N79 / N77 frequency band, so that a total of 2 antenna bodies supporting the LTE frequency band and 4 antenna bodies supporting the N78 / N79 / N77 frequency band are realized through five antenna bodies, and the reception and transmission of radio frequency signals in the N78 / N79 / N77 frequency band of 5G NSA can be realized.
[0082] Among them, the antenna body 21 on the mainboard 20 is arranged close to the first short frame 101a and the second long frame 102b, and the third antenna body ANT2, the fourth antenna body ANT3, the fifth antenna body ANT4, the sixth antenna body ANT5 and the ninth antenna body ANT8 are roughly arranged around the metal frame 10 to form a surrounding 5G antenna.
[0083] See also Figure 5 , is a schematic plan view of an electronic device 100 in an embodiment of the present application showing the antenna structure of the N41 frequency band of 5G SA. In order to show it more clearly, Figure 5 The same simplification is also carried out. Figure 1 Some components are omitted.
[0084] like Figure 5As shown, the N41 frequency band of the 5G SA of the present application is composed of the first antenna body ANT0, the second antenna body ANT1, the third antenna body ANT2 and the fourth antenna body ANT3.

Among them, the first antenna body ANT0, the second antenna body ANT1, the third antenna body ANT2 and the fourth antenna body ANT3 are roughly arranged around the metal frame 10 to form a surrounding 5G antenna.
[0085] See also Figure 6 , is a schematic plan view of an electronic device 100 in an embodiment of the present application showing the antenna structure of the N78 / N79 / N77 frequency band of 5G SA. In order to show it more clearly, Figure 6 The same simplification is also carried out. Figure 1 Some components are omitted.
[0086] like Figure 6 As shown, the N78 / N79 / N77 frequency band of the 5G SA of the present application is composed of the third antenna body ANT2, the fifth antenna body ANT4, the sixth antenna body ANT5 and the ninth antenna body ANT8. That is, the antenna architecture of the N78 / N79 / N77 frequency band of the 5G SA includes the third antenna body ANT2, the fifth antenna body ANT4, the sixth antenna body ANT5 and the ninth antenna body ANT8, and the four antenna bodies realize the reception and transmission of the RF signal of the N78 / N79 / N77 frequency band under the 5G SA communication standard.
[0087] Among them, the antenna body 21 on the mainboard 20, that is, the ninth antenna body ANT8 is arranged close to the first short frame 101a and the second long frame 102b, and the third antenna body ANT2, the fifth antenna body ANT4, the sixth antenna body ANT5 and the ninth antenna body ANT8 are arranged roughly around the metal frame 10 of the electronic device 100, forming a surrounding 5G antenna.
[0088] Therefore, as described above, the frequency bands supported by the antenna device 200 of the present application actually include multiple frequency bands of GPS, multiple frequency bands of WIFI 2.4G / 5G, multiple frequency bands of 2 / 3 / 4G, N41, N78 / N79 of 5G NSA, N41, N78 / N79 of 5G SA and other multiple frequency bands under multiple communication standards.
[0089] Among them, in the present application, when the electronic device 100 is in a network state of 4G communication standard, several antenna bodies supporting 2 / 3 / 4G can switch between main set and diversity according to signal strength. When the electronic device 100 is in a network state of 5G NSA communication standard, several antenna bodies supporting 5G NSA can also switch between main set and diversity according to signal strength.
[0090] Specifically, the plurality of antenna bodies supporting 2 / 3 / 4G can switch between the main set and the diversity according to the signal strength, including: switching the antenna body with a relatively strong signal among the plurality of antenna bodies supporting 2 / 3 / 4G to the main set antenna and switching the antenna body with a relatively weak signal therein to the diversity antenna. Similarly, the plurality of antenna bodies supporting 5G NSA can switch between the main set and the diversity according to the signal strength, including: switching the antenna body with a relatively strong signal among the plurality of antenna bodies supporting 5G NSA to the main set antenna and switching the antenna body with a relatively weak signal therein to the diversity antenna.
[0091] See also Figure 7 , is a schematic diagram of switching of an antenna body supporting 2 / 3 / 4G in the electronic device 100 of the present application. In order to show more clearly, Figure 7 The same simplification is also carried out. Figure 1 Some components are omitted.
[0092] As mentioned above, the frequency band supported by the first antenna body ANT0 is the LMHB PRX frequency band, and the frequency band supported by the second antenna body ANT1 is the LMHB DRX+N41 DRX MIMO; therefore, the first antenna body ANT0 and the second antenna body ANT1 both independently support 2 / 3 / 4G communication standards.
[0093] Therefore, when the electronic device 100 is in a network state of the 4G communication standard, an antenna pair is formed between the first antenna body ANT0 and the second antenna body ANT1, and the main set and the diversity set can be switched according to the signal strength.
[0094] like Figure 1 and Figure 7 As shown, since the first antenna body ANT0 is located on the second long frame 102b, and the second antenna body ANT1 is located on the second short frame 101b, no matter the user holds the electronic device 100 horizontally or vertically, at least one of the first antenna body ANT0 and the second antenna body ANT1 will not be held by the user, and the signal is good. At this time, the main set and the diversity set are switched according to the signal strength, and the signal quality of the LB frequency band of 2 / 3 / 4G can be guaranteed no matter the user holds the device horizontally or vertically.
[0095] See also Figure 8, is a schematic diagram of switching of an antenna body supporting the N41 frequency band in the electronic device 100 of the present application. In order to show more clearly, Figure 8 The same simplification is also carried out. Figure 1 Some components are omitted.
[0096] As mentioned above, the frequency band supported by the third antenna body ANT2 is MHB MIMO2+N41 PRX+N78 / N79 / N77 PRX MIMO, and the frequency band supported by the fourth antenna body ANT3 is: N41 DRX.
[0097] Therefore, the third antenna body ANT2 and the fourth antenna body ANT3 both support the N41 frequency band. When the electronic device 100 is in a network state of 5G NSA or 5G SA communication standard, for the N41 frequency band, the third antenna body ANT2 and the fourth antenna body ANT3 form an antenna pair, and the main set and diversity can be switched according to the signal strength.
[0098] like Figure 1 and Figure 8 As shown, since the third antenna body ANT2 is located on the first short frame 101a, and the fourth antenna body ANT3 is located on the second long frame 102b, no matter the user holds the device horizontally or vertically, at least one of the third antenna body ANT2 and the fourth antenna body ANT3 will not be held by the user, and the signal is better. At this time, for the N41 frequency band, the first antenna body ANT0 and the fifth antenna body ANT4 switch the main set and the diversity according to the signal strength to ensure the signal quality of the N41 frequency band of the 5G NSA communication standard.
[0099] See also Fig. 9 , is a schematic diagram of switching of an antenna body supporting 5G N78 / N79 / N77 frequency bands in the electronic device 100 of the present application. In order to show more clearly, Fig. 9 The same simplification is also carried out. Figure 1 Some components are omitted.
[0100] As mentioned above, the third antenna body ANT2, the fifth antenna body ANT4, the sixth and fifth antenna body ANT5 and the ninth antenna body ANT8 all support the N78 / N79 / N77 frequency bands. When the electronic device 100 is in the network state of the 5G NSA or 5G SA communication standard, for the N78 / N79 / N77 frequency bands, the third antenna body ANT2, the fifth antenna body ANT4, the sixth and fifth antenna body ANT5 and the ninth antenna body ANT8 form an antenna pair / group, and the main set and the diversity set can be switched according to the signal strength.
[0101] Similarly, no matter the user holds the device horizontally or vertically, at least one of the third antenna body ANT2, the fifth antenna body ANT4, and the sixth and fifth antenna body ANT5 will not be held by the user, and the signal is good. At this time, for the N78 / N79 / N77 frequency band, the third antenna body ANT2, the fifth antenna body ANT4, and the sixth and fifth antenna body ANT5 switch the main set and the diversity set according to the signal strength to ensure the signal quality of the N78 / N79 / N77 frequency band of the 5G NSA communication standard.
[0102] Among them, for an antenna group consisting of more than two antenna bodies, the strongest antenna body can be selected as the main set, and the other antenna bodies can be used as diversity. For example, among the third antenna body ANT2, the fifth antenna body ANT4, the sixth antenna body ANT5 and the ninth antenna body ANT8, when the signal strength of the third antenna body ANT2 is the highest, the third antenna body ANT2 is selected as the main set, and the others are used as diversity.
[0103] Among them, the above-mentioned N41 frequency band ranges from 2.5-2.69GHz, the N78 frequency band ranges from 3.3-3.8GHz, and the N79 frequency band ranges from 4.8-5GHz.
[0104] See also Fig.10 , is a structural block diagram of some components of the electronic device 100. The electronic device 100 includes an antenna device 200, a signal detector 300 and a radio frequency processing circuit 400, wherein the signal detector 300 is used to detect the signal strength of each pair of antenna bodies that can switch between the main set and the diversity according to the signal strength. The radio frequency processing circuit 400 is connected to the signal detector 300, and is used to switch and control each pair of antenna bodies that can switch between the main set and the diversity according to the signal strength detected by the signal detector 300.
[0105] Specifically, the RF processing circuit 400 determines, based on the signal strength detected by the signal detector 300, that the difference in signal strength of a pair of antenna bodies that can switch between the main set and the diversity according to the signal strength exceeds a preset threshold, and when the antenna body with the lower current signal strength is the main set, the antenna body with the lower current signal strength is controlled to be switched to the diversity, and the antenna body with the higher current signal strength is controlled to be switched to the main set.
[0106] The preset threshold may be 6db.
[0107] For example, for the antenna pair including the first antenna body ANT0 supporting the LMHB PRX frequency band and the second antenna body ANT1 supporting the LMHB DRX+N41 DRXMIMO frequency band, the RF processing circuit 400 controls the first antenna body ANT0 to be switched to the main set and the second antenna body ANT1 to be switched to the diversity set when the signal strength of the first antenna body ANT0 detected by the signal detector 300 is greater than the signal strength of the second antenna body ANT1, and the difference between the two exceeds a preset threshold and the first antenna body ANT0 is a diversity antenna at this time.
[0108] The RF processing circuit 400 may include components such as a controller and a switch to implement switching between the main set and the diversity set.

Therefore, the extension portion Y1 of the third frame segment 12c and the extension portion Y2 of the fourth frame segment 12d both have a large area of contact with the front shell 30, so that the front shell 30 is supported while achieving grounding, thereby enhancing the stability of the entire structure.

Specifically, the end of the second frame segment 12b adjacent to the gap 11a is connected to the RF source S1 near the end, and the other end adjacent to the gap 11b is grounded.
[0118] One end of the sixth frame segment 12h constituting the seventh antenna body ANT6 is connected to the RF source S1 near the end, and the other end is grounded. The other end of the sixth frame segment 12f also extends inward, that is, toward the front shell 30 ( Figure 1 The sixth frame segment 12f is connected to the front shell 30 by the black part between the sixth frame segment 12f and the front shell 30 to achieve grounding, thereby forming a complete feeding circuit. Specifically, the end of the sixth frame segment 12f adjacent to the gap 11a is connected to the RF source S1 near the end, and the other end adjacent to the gap 11e is grounded.
[0119] Among them, the sixth frame segment 12h is "L"-shaped, and the two sections of the sixth frame segment 12h are respectively connected to a part of the first short frame 101a and the first long frame 102a located at the top corners, the RF source S1 is connected to the part of the sixth frame segment 12h located at the first short frame 101a, and the end of the part of the sixth frame segment 12h located at the first long frame 102a is grounded.

[0125] The position of the fifth frame segment 12e located between the RF source S1 and the gap 11i is connected to the ground on the mainboard 20 through a frequency modulation switch K3 to achieve grounding.
[0126] Specifically, all RF sources S1 and all FM switches K1, K2, K3 and K4 are arranged on the main board 20, and the FM switches K2, K3 and K4 are grounded to the ground on the main board 20. The attached figure of the present application is only a schematic diagram. For example, the actual positions of the RF source S1 and the FM switch K1 connected to the frame segment 12 of the second short frame 101b should be located on the main board 20. However, in order to show it more clearly, they are drawn outside the main board 20. In fact, for the frame segment 12 far from the main board 20, the frame segment 12 and the RF source S1 on the main board 20 can be electrically connected through wires, springs, etc.
[0127] The ground on the mainboard 20 is connected to the front shell to form a common ground.
[0128] The frequency modulation switches K1, K2, K3 and K4 are switches connected with frequency modulation elements such as capacitors and / or inductors. The frequency modulation switches S1, K2, K3 and K4 play a matching role, that is, a matching circuit.

The insulating layer and the metal frame 10 together constitute the frame of the electronic device 100.
[0131] The electronic device 100 may also include a display screen and a glass cover plate, etc., which are not described or illustrated because they are irrelevant to the improvement of the present invention.

[0133] The electronic device 100 and antenna device 200 provided by the present invention can support frequency bands under multiple communication standards including 5G NSA, 5G SA, WIFI, GPS, and 2 / 3 / 4G by using multiple frame segments of the metal frame 10 as antenna bodies, thereby meeting communication requirements and minimizing the number of antennas set inside the device. In addition, some of the frame segments 12 among the multiple frame segments 12 are connected to the radio frequency source S1, and at least one frame segment 12 is not connected to the radio frequency source S1. The frame segment 12 not connected to the radio frequency source S1 is coupled with the adjacent frame segment 12 connected to the radio frequency source S1, and the reinforced antenna body or parasitic antenna body of the antenna body formed by the frame segment connected to the radio frequency source can reduce the number of radio frequency sources, and improve the antenna performance or increase the antenna frequency band. In addition, compared with the existing architecture that requires six antennas under the 5G NSA communication standard, the present application can reduce one antenna body, which is more conducive to the overall layout of the antenna, and can also reduce the number of antennas arranged on the mainboard 20, reducing costs and improving the overall performance of the antenna.
