[0017] 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.

[0018] 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.

[0019] 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 the metal frame 10 is provided with a plurality of gaps 11, and the plurality of gaps 11 separate the metal frame 10 into a plurality of independent frame segments 12, and the plurality of frame segments 12 are used as antenna bodies and support frequency bands of multiple 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 MHB frequency band of LTE, and outside the at least three frame segments supporting the 5G frequency band, at least one frame segment supports the MHB (Middle highband) frequency band of LTE; wherein, the at least one frame segment supporting the MHB 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.

[0020] Therefore, in the present application, by having at least one of the at least three border segments supporting the 5G frequency band simultaneously support the MHB frequency band of LTE, the number of antenna bodies can be reduced; and the 5G NSA communication standard is realized by having the at least one border segment supporting the MHB frequency band of LTE outside the at least three border segments supporting the 5G frequency band and the at least three border segments supporting the 5G frequency band, and the 5G NSA communication standard is mainly realized by a metal frame, which improves antenna performance and reduces costs.

[0021] 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.

[0022] 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 MHB refers to the medium and high frequency under the 4G LTE communication standard.

[0023] In some embodiments, at least one slit is formed in a portion of the metal frame 10 located at the bottom end D1 of the electronic device 100 .

[0024] Therefore, in the present application, by using multiple frame segments of the metal frame 10 as antenna bodies, it is possible to support frequency bands under multiple communication standards including 5GNSA, 5G SA, WIFI, GPS, and 2 / 3 / 4G, thereby meeting communication needs. At least one gap is opened in the metal frame 10 at the bottom of the electronic device 100, which can reduce or avoid opening a gap at the bottom of the side of the metal frame 10 located on the electronic device 100, thereby avoiding the impact caused by the user holding it during use.

[0025] 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.

[0026] 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.

[0027] 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. For example, 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.

[0028] like Figure 1 As shown, in this embodiment, the number of the plurality of RF sources S1 is greater than or equal to the number of the plurality of frame segments 12, and each frame segment 12 is connected to at least one RF source S1. That is, in this embodiment, each frame segment 12 is connected to a RF source S1, and at least one RF source S1 is connected.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] In some embodiments, at least one of the plurality of frame bodies 12 independently supports a frequency band under a certain communication standard, and at least some of the frame bodies 12 cooperate with at least other frame bodies to support a frequency band under a certain communication standard.

[0035] Among them, the "at least part of the frame body 12 cooperates with at least other frame bodies to support a frequency band under a certain communication standard" includes: multiple frame bodies 12 cooperate to support a frequency band under a certain communication standard, or multiple frame bodies 12 cooperate with the antenna body 21 on the mainboard 20 to support a frequency band under a certain communication standard.

[0036] 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.

[0037] 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.

[0038] 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. 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 on the left side of the electronic device 100, and the second long frame 102b is located on the right side of the electronic device 100.

[0039] 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.

[0040] The second short frame 101b is provided with a connection interface such as a USB interface.

[0041] like Figure 1 As shown, in this embodiment, the first short frame 101a has two slits 11a and 11b, the second short frame 101b has one slit 11c, the first long frame 102a has two slits 11d and 11e, and the second long frame 102b has one slit 11f.

[0042] That is, in this embodiment, the metal frame 10 is provided with 6 slits 11, which divide the metal frame into six 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.

[0043] The slits 11a and 11b provided on the first short frame 101a are respectively close to the first long frame 102a and the second long frame 102b, the two slits 11d and 11e provided on the first long frame 102a are both provided close to the first short frame 101a, and the slit 11d is closer to the first short frame 101a than the slit 11e. The slit 11c provided on the second short frame 101b is provided close to the first long frame 102a, and the slit 11f provided on the second long frame 102b is provided close to the first short frame 101a.

[0044] Therefore, the two slits 11d and 11e provided on the first long frame 102a on the metal frame 10 and the slit 11f 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 on the side of the electronic device 100 near the bottom. 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 a slit here, the user's holding will not affect the antenna radiation. 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.

[0045] Specifically, the six frame segments 12 include a first frame segment 12a located between the gaps 11a and 11b, a second frame segment 12b located between the gaps 11b and 11f, a third frame segment 12c located between the gaps 11f and 11c, a fourth frame segment 12d located between the gaps 11c and 11e, a fifth frame segment 12e located between the gaps 11e and 11d, and a sixth frame segment 12f located between the gap 11d and the gap 11a.

[0046] The first frame segment 12a, the second frame segment 12b, the fifth frame segment 12e and the sixth frame segment 12f are each connected to a radio frequency source S1, and the third frame segment 12c and the fourth frame segment 12d are respectively connected to two radio frequency sources S1.

[0047] The preset portion B1 of the third frame segment 12c located between the two RF sources S1 is grounded, and the third frame segment 12c is actually divided into two antenna bodies, and the two RF sources S1 are respectively connected to the two antenna bodies. The preset portion B2 of the fourth frame segment 12d located between the two RF sources S1 is also grounded, and the fourth frame segment 12d is actually divided into two antenna bodies, and the two RF sources S1 are respectively connected to the two antenna bodies.

[0048] The preset portion of the third frame segment 12c located between the two RF sources S1 is a portion of the third frame segment 12c located in the region between the two RF sources S1, and there is a gap between the two RF sources S1 and the preset grounded portion of the third frame segment 12c, and feed loops are formed respectively. The preset portion of the fourth frame segment 12d located between the two RF sources S1 is also a portion of the region between the two RF sources S1, and there is a gap between the two RF sources S1 and the preset grounded portion of the fourth frame segment 12d, and feed loops are formed respectively.

[0049] The first frame segment 12a, the second frame segment 12b, the fifth frame segment 12e and the sixth frame segment 12f each constitute an antenna body. Therefore, in the present application, the plurality of frame segments 12 actually form eight antenna bodies.

[0050] Specifically, the portion of the third frame segment 12c located between the gap 11f and the grounding portion (i.e., the aforementioned preset grounding portion B1) constitutes the first antenna body ANT0, and the portion of the third frame segment 12c located between the gap 11c and the grounding portion (i.e., the aforementioned preset grounding portion B1) constitutes the second antenna body ANT1. The first frame segment 12a constitutes the third antenna body ANT2, and the portion of the fourth frame segment 12d located between the gap 11c and the grounding portion (i.e., the aforementioned preset grounding portion B2) constitutes the fourth antenna body ANT3. The fifth frame segment 12e constitutes the fifth antenna body ANT4, and the second frame segment 12b constitutes the sixth antenna body ANT5. The sixth frame segment 12f constitutes the seventh antenna body ANT6. The portion of the fourth frame segment 12d located between the gap 11e and the grounding portion (i.e., the aforementioned preset grounding portion B2) constitutes the eighth antenna body ANT7.

[0051] Among them, together with the antenna body 21 located on the mainboard 20 as mentioned above, in this application, a total of nine antenna bodies are formed by the metal frame 10 and the antenna body 21 on the mainboard. 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 to ANT8 are actually formed.

[0052] Among them, the frequency bands supported by the first antenna body ANT0 are LB DRX+MHB MIMO2+N41PRX. Among them, in this application, LB refers to the low frequency band (low band), MHB refers to the middle high band (middle high band), and N41 refers to the N41 frequency band under the 5G NSA communication standard. That is, the frequency bands supported by the first antenna body ANT0 are low frequency + middle high frequency + N41. Among them, LB DRX refers to the diversity antenna body of the first antenna body ANT0 which defaults to the low frequency band, and N41 PRX refers to the main antenna body of the first antenna body ANT0 which defaults to the N41 frequency band. MHB MIMO2 refers to the multiple input and output (middle high band, multiple input multiple output) antenna system supported by the first antenna body ANT0 in the middle and high frequency bands.

[0053] The frequency band supported by the second antenna body ANT1 is LB PRX, that is, the frequency band supported by the second antenna body ANT1 is low frequency. LB PRX means that the second antenna body ANT1 is a main antenna body of the low frequency band by default.

[0054] The frequency band supported by the third antenna body ANT2 is MHB PRX+N78 / N79 PRX, wherein N78 / N79 refers to the N78 / N79 frequency band under the 5G NSA communication standard, that is, the frequency band supported by the third antenna body ANT2 is medium and high frequency + N78 / N79. Among them, MHB PRX refers to the main antenna body of the third antenna body ANT2 that defaults to the medium and high frequency band, and N78 / N79PRX refers to the main antenna body of the third antenna body ANT2 that defaults to the N78 / N79 frequency band.

[0055] The frequency bands supported by the fourth antenna body ANT3 are: MHB DRX+N41 MIMO2, that is, the fourth antenna body ANT3 supports medium and high frequency bands and N41 frequency bands. Among them, MHB DRX means that the fourth antenna body ANT3 defaults to a diversity antenna in the medium and high frequency bands, and N41 MIMO2 means that the fourth antenna body ANT3 supports multiple input and output antennas in the N41 frequency band.

[0056] The frequency bands supported by the fifth antenna body ANT4 are: MHB MIMO3+N41 DRX+N78 / N79DRX, that is, the frequency bands supported by the fifth antenna body ANT4 are medium and low frequency+N41+N78 / N79 frequency bands. Among them, MHB MIMO3 means that the fifth antenna body ANT4 is a multiple input and output antenna system supporting medium and high frequency bands, N41 DRX means that the fifth antenna body ANT4 defaults to the diversity antenna of N41, and N78 / N79 DRX means that the fifth antenna body ANT4 defaults to the diversity antenna of N78 / N79.

[0057] The frequency band supported by the sixth antenna body ANT5 is: N78 / N79 MIMO3, that is, the frequency band supported by the fourth antenna body ANT3 is the N78 / N79 frequency band, and the sixth antenna body ANT5 supports the multiple input and output antenna system under the N78 / N79 frequency band.

[0058] The frequency band supported by the seventh antenna body ANT6 is: GPS L1+WIFI 2.4G / 5G+N41 MIMO3, that is, the frequency band supported by the seventh antenna body ANT6 is GPS L1 band+WIFI 2.4G / 5G band+N41 band, and the seventh antenna body ANT6 supports a multi-input and output antenna system under the N78 / N79 band.

[0059] 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.

[0060] The frequency band supported by the eighth antenna body ANT7 is: ANT8: GPS L5+WIFI 5G+WIFI 2.4G, that is, the frequency band supported by the eighth antenna body ANT7 is GPS L5 band+WIFI 2.4G band+WIFI 5G band.

[0061] Among them, the antenna body 21 located on the mainboard 20 constitutes the ninth antenna body ANT8, and supports the frequency band N78 / N79 MIMO, that is, the frequency band supported by the antenna body 21 located on the mainboard 20 is the N78 / N79 frequency band under the 5G NSA communication standard, and supports the multiple input and output antenna system under the N78 / N79 frequency band.

[0062] Among them, since the N78 / N79 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 antenna performance.

[0063] 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.

[0064] Among them, as mentioned above, the frequency bands supported by the first antenna body ANT0 are the three frequency bands of LB+MHB MIMO2+N41, and the frequency band supported by the second antenna body ANT1 is LB; 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 2 / 3 / 4G communication standards to realize the reception and transmission of radio frequency signals of 2 / 3 / 4G communication standards.

[0065] The frequency band supported by the third antenna body ANT2 is MHB+N78 / N79, and it supports the 2 / 3 / 4G communication standard alone, that is, it can work alone in the 2 / 3 / 4G communication standard to realize the transmission and reception of the radio frequency signal of the 2 / 3 / 4G communication standard. The third antenna body ANT2 also supports the N78 / N79 frequency band. The frequency band supported by the fourth antenna body ANT3 is MHB+N41 MIMO2, and it also supports the frequency band of the 2 / 3 / 4G communication standard alone, and also supports the N41 frequency band.

[0066] As mentioned above, the frequency band supported by the seventh antenna body ANT6 is: GPS L1+WIFI2.4G / 5G+N41 MIMO3, and the frequency band supported by the eighth antenna body ANT7 is: ANT8: GPS L5+WIFI 5G+WIFI 2.4G. The seventh antenna body ANT6 and the eighth antenna body ANT7 each support the frequency bands under the GPS and WIFI communication standards, that is, both can independently realize the reception and transmission of RF signals of GPS and WIFI communication standards. Among them, 4G and LTE in this application refer to 4G LTE.

[0067] 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 dual frequency bands.

[0068] 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.

[0069] See also Figure 2 , is a schematic plan view of an electronic device 100 in an embodiment of the present application illustrating the antenna architecture composition of the N41 frequency band of 5G NSA. In order to clearly illustrate the antenna architecture composition of the N41 frequency band of 5G NSA, Figure 2 Simplified, compared Figure 1 Some components are omitted.

[0070] Specifically, the N41 frequency band of 5G NSA is supported by the first antenna body ANT0, the third antenna body ANT2, the fourth antenna body ANT3, the fifth antenna body ANT4 and the seventh antenna body ANT6. That is, the antenna architecture of the N41 frequency band of 5G NSA includes the first antenna body ANT0, the third antenna body ANT2, the fourth antenna body ANT3, the fifth antenna body ANT4 and the seventh antenna body ANT6. In this embodiment, the fourth antenna body ANT3 at least supports the LTE and N41 dual frequency bands and can replace the existing two antenna bodies, the third antenna body ANT2 supports the LTE frequency band, the first antenna body ANT0, the fifth antenna body ANT4 and the seventh antenna body ANT6 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.

[0071] The first antenna body ANT, the third antenna body ANT2, the fourth antenna body ANT3, the fifth antenna body ANT4 and the seventh antenna body ANT6 are arranged roughly around the metal frame 10 to form a surrounding 5G antenna.

[0072] Obviously, in other implementations, other antennas may also support LTE and N41 dual frequency bands, as long as at least one antenna body supports both LTE and N41 dual frequency bands.

[0073] See also Figure 3 , 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 frequency band of 5G NSA. In order to show it more clearly, Figure 3 The same simplification is also carried out. Figure 1 Some components are omitted.

[0074] Specifically, the N78 / N79 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 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. In this embodiment, the third antenna body ANT2 supports the frequency band of MHB+N78 / N79, and supports both LTE and N78 / N79 dual frequency bands and can replace the existing two antenna bodies. The fourth antenna body ANT3 supports the LTE frequency band, and the fifth antenna body ANT4, the sixth antenna body ANT5 and the ninth antenna body ANT8 all support the N78 / N79 frequency band. Thus, through the five antenna bodies, a total of 2 antenna bodies supporting the LTE frequency band and 4 antenna bodies supporting the N78 / N79 frequency band are realized, and the reception and transmission of radio frequency signals in the N78 / N79 frequency band of 5G NSA can be realized.

[0075] Among them, the antenna body 21 on the mainboard 20 is arranged close to the first short frame 101a and the second long frame 101b, 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.

[0076] See also Figure 4 , 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 4 The same simplification is also carried out. Figure 1Some components are omitted.

[0077] like Figure 4 As shown, the N41 frequency band of the 5G SA of the present application is composed of the first antenna body ANT0, 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 the 5G SA includes the first antenna body ANT0, the third antenna body ANT2, the fourth antenna body ANT3 and the fifth antenna body ANT4, and the four antenna bodies are used to realize the reception and transmission of the radio frequency signal of the N41 frequency band under the 5GSA communication standard. Among them, the first antenna body ANT0, the third antenna body ANT2, the fourth antenna body ANT3 and the fifth antenna body ANT4 are roughly arranged around the metal frame 10 to form a surrounding 5G antenna.

[0078] 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 N78 / N79 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.

[0079] like Figure 5 As shown, the N78 / N79 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 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 transmission and reception of the radio frequency signals of the N78 / N79 frequency band under the 5G SA communication standard.

[0080] Among them, the antenna body 21 on the mainboard 20 is arranged close to the first short frame 101a and the second long frame 101b, 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 to form a surrounding 5G antenna.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] See also Figure 6 , 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 6 The same simplification is also carried out. Figure 1 Some components are omitted.

[0085] As mentioned above, the first antenna body ANT0 supports the three frequency bands of LB+MHB MIMO2+N41, the second antenna body ANT1 supports the frequency band of LB; the third antenna body ANT2 supports the frequency band of MHB+N78 / N79, and the fourth antenna body ANT3 supports the frequency band of MHB+N41MIMO2, namely the medium and high frequency and N41 frequency bands.

[0086] Thus, when the electronic device 100 is in a network state of the 4G communication standard, the first antenna body ANT0 and the second antenna body ANT1, both supporting LB (low frequency), form an antenna pair, and can switch the main set and the diversity according to the signal strength; the third antenna body ANT2 and the fourth antenna body ANT3 supporting medium and high frequencies form an antenna pair, and can switch the main set and the diversity according to the signal strength.

[0087] like Figure 1 and Figure 6As 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.

[0088] like Figure 1 and Figure 6 As shown, since the third antenna body ANT2 is located on the first short frame 101a, and the fourth antenna body ANT3 is located at the second short frame 101b and the top corner of the first long frame, the third antenna body ANT2 and the fourth antenna body ANT3 are roughly diagonally distributed on the electronic device 100. At this time, no matter whether the user holds the electronic device 100 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, the main set and the diversity set are switched according to the signal strength, and the signal quality of the MHB frequency band of 2 / 3 / 4G can be guaranteed regardless of whether the user holds the device horizontally or vertically.

[0089] See also Figure 7 , is a schematic diagram of switching of an antenna body supporting 5G NSA 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.

[0090] As mentioned above, the first antenna body ANT0 supports the three frequency bands of LB+MHB MIMO2+N41, the third antenna body ANT2 supports the frequency bands of MHB+N78 / N79, and the fifth antenna body ANT4 supports the frequency bands of MHB MIMO3+N41 DRX+N78 / N79 DRX.

[0091] Thus, the fifth antenna body ANT4 supports both the N41 frequency band and the N78 / N79 frequency band. When the electronic device 100 is in the network state of the 5G NSA communication standard, for the N41 frequency band, the first antenna body ANT0 and the fifth antenna body ANT4 form an antenna pair, and the main set and the diversity can be switched according to the signal strength. For the N78 / N79 frequency band, the third antenna body ANT2 and the fifth antenna body ANT4 form an antenna pair, and the main set and the diversity can also be switched according to the signal strength.

[0092] like Figure 1 and Figure 7As shown, since the first antenna body ANT0 is located on the second long frame 102b, the third antenna body ANT2 is located on the first short frame 101a, and the fifth antenna body ANT4 is located on the first long frame 102a, no matter whether the user holds it horizontally or vertically, at least one of the first antenna body ANT0 and the fifth antenna body ANT4 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. Similarly, no matter whether the user holds it horizontally or vertically, at least one of the third antenna body ANT2 and the fifth antenna body ANT4 will not be held by the user, and the signal is better. At this time, for the N78 / N79 frequency band, the third antenna body ANT2 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 N78 / N79 frequency band of the 5G NSA communication standard.

[0093] 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.

[0094] See also Figure 8 , 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.

[0095] 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.

[0096] The preset threshold may be 6db.

[0097] For example, for the antenna pair of the first antenna body ANT0 and the second antenna body ANT1 supporting LB (low frequency), the RF processing circuit 400 controls the first antenna body ANT0 to be switched to the main antenna and the second antenna body ANT1 to be switched to the diversity antenna 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.

[0098] 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.

[0099] Among them, Figure 1-5 As shown in the drawings, the electronic device 100 further includes a front shell 30 , and the front shell 30 is used to support a display screen of the electronic device 100 and to provide a ground for the entire device.

[0100] Among them, Figure 1 As shown, the preset portion B1 of the third frame segment 12c located between the two RF sources S1 extends an extension portion Y1 inwardly, that is, in the direction of the front shell 30, and the extension portion Y1 contacts the front shell 30 to achieve grounding. The preset portion B2 of the fourth frame segment 12d located between the two RF sources S1 extends an extension portion Y2 inwardly, that is, in the direction of the front shell 30, and the extension portion Y2 contacts the front shell 30 to achieve grounding.

[0101] The length of the preset portion B1 and the extension portion Y1 along the direction of the third frame segment 12c exceeds the preset length, and the length of the preset portion B2 and the extension portion Y2 along the direction of the fourth frame segment 12d also exceeds the preset length, for example, both exceed 1 / 3 of the length of the first long frame 102a / the second long frame 102b of the metal frame 10. 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.

[0102] Among them, Figure 1 As shown, one end of the first frame segment 12a constituting the third antenna body ANT2 is connected to the RF source S1 near the end, and the other end is grounded. The other end of the first frame segment 12a extends inward, that is, toward the front shell 30 ( Figure 1The black part between the first frame segment 12a and the front shell 30 in the embodiment of the present invention is connected to the front shell 30 to achieve grounding, thereby forming a complete feeding circuit. Specifically, the end of the first frame segment 12a adjacent to the gap 11b is connected to the RF source S1, and the other end adjacent to the gap 11a is grounded.

[0103] One end of the fifth frame segment 12e constituting the fifth antenna body ANT4 is connected to the RF source S1 near the end, and the other end is grounded. The other end of the fifth frame segment 12e also extends inward, that is, toward the front shell 30 ( Figure 1 The fifth frame segment 12e is connected to the front shell 30 by the black part between the fifth frame segment 12e and the front shell 30 to achieve grounding, thereby forming a complete feeding circuit. Specifically, the end of the fifth frame segment 12e adjacent to the gap 11d is connected to the RF source S1 near the end, and the other end adjacent to the gap 11e is grounded.

[0104] One end of the second frame segment 12b constituting the sixth antenna body ANT5 is connected to the RF source S1 near the end, and the other end is grounded. The other end of the second frame segment 12b also extends inward, that is, toward the front shell 30 ( Figure 1 The black part between the second frame segment 12b and the front shell 30 in the embodiment of the present invention is connected to the front shell 30 to achieve grounding, thereby forming a complete feeding circuit. Specifically, the end of the second frame segment 12b adjacent to the gap 11f is connected to the RF source S1 near the end, and the other end adjacent to the gap 11b is grounded.

[0105] One end of the sixth frame segment 12f 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 11d is grounded.

[0106] That is, the first frame segment 12a, the fifth frame segment 12e, the second frame segment 12b and the sixth frame segment 12f are connected to the radio frequency source S1 at one end close to the end thereof, and the other end is grounded.

[0107] The grounded portions of the first frame segment 12a, the fifth frame segment 12e, the second frame segment 12b and the sixth frame segment 12f also have a certain length in a direction perpendicular to the extension direction, and can contact the front shell 30 to increase the overall structural strength.

[0108] Among them, in this application, Figure 1 As shown, a tuning switch (SW) K1 is connected between all the RF sources S1 and the corresponding frame segments 12 , that is, each RF source S1 is connected to the corresponding frame segment 12 via the tuning switch K1 .

[0109] like Figure 1 As shown, the position of the first antenna body ANT0 between the RF source S1 and the preset position B2 is also grounded through a frequency modulation switch K2. The position of the second antenna body ANT1 on the side of the RF source S1 away from the preset position B2, that is, the position of the second antenna body ANT1 between the RF source S1 and the gap 11c is also grounded through a frequency modulation switch K3.

[0110] Specifically, all RF sources S1 and all FM switches K1, K2 and K3 are arranged on the main board 20, the FM switch K2 is connected between the first antenna body ANT0 and the ground on the main board 20 to achieve grounding, and the FM switch K3 is connected between the second antenna body ANT1 and the ground on the main board 20 to achieve grounding. Among them, the accompanying drawings of the present application are only schematic diagrams. 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 by wires, springs, etc.

[0111] The ground on the mainboard 20 is connected to the front shell to form a common ground.

[0112] The frequency modulation switches K1, K2 and K3 are switches connected with frequency modulation elements such as capacitors and / or inductors. The frequency modulation switches S1, K2 and K3 play a matching role, that is, they are matching circuits.

[0113] The frequency modulation switches K1, K2 and K3 are all part of the structure of the antenna device 200. That is, the antenna device 200 may include the aforementioned metal frame 10, antenna body 21, radio frequency source S1, frequency modulation switches K1, K2 and K3, etc.

[0114] See also Fig. 9 , is an equivalent schematic diagram of the feeding structure of the first antenna body ANT0. Fig. 9As shown, the RF source S1 corresponding to the first antenna body ANT0 is connected to one end of the first antenna body ANT0 through the tuning switch K1, and the other end of the first antenna body ANT0 is directly grounded, that is, connected to the front shell 30 through the aforementioned preset position B2; the connection position between the RF source S1 and the first antenna body ANT0 and the grounding position of the other end is also grounded through the frequency modulation switch K2. Therefore, the excitation signal generated by the RF source S1 can be grounded through the frequency modulation switch K2, and can also be directly grounded through the other end to form a multi-loop feeding path, thereby realizing an antenna structure covering the three frequency bands of LB+MHB MIMO2+N41.

[0115] In some embodiments, the electronic device 100 further includes an insulating layer covering the outer periphery of the metal frame 10, the insulating layer is made of an insulating material, and is used to cover the gap of the metal frame 10 to improve the appearance consistency, and because the insulating layer is made of an insulating material, it will not affect the radiation of the antenna signal. The insulating layer and the metal frame 10 together constitute the frame of the electronic device 100.

[0116] In other embodiments, some of the 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. That is, in other embodiments, only some of the frame segments 12 are connected to the RF source S1.

[0117] The frame segment 12 not connected to the RF source S1 is grounded, and is coupled with the adjacent frame segment 12 connected to the RF source S1, and serves as a reinforced antenna body or a parasitic antenna body of the antenna body formed by the frame segment connected to the RF source.

[0118] Thus, in other embodiments, some of the frame segments 12 among 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, and 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.

[0119] 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. Figure 1 The cross-sectional views described in the figures are schematic diagrams without structures such as a display screen and a glass cover plate, and only illustrate the component structures involved in the present invention.

[0120] The electronic device 100 may be a mobile phone or a tablet computer.

[0121] 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 needs. At least one slit is opened at the bottom of the metal frame 10 of the electronic device 100, which can reduce or avoid the opening of the metal frame 10 at the bottom of the side of the electronic device 100, thereby avoiding the impact caused by the user holding it during use. 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 layout of the antenna on the mainboard 20, reducing costs and improving the overall performance of the antenna.

[0122] The above is an implementation of the embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the embodiment of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
