Fig. 1 is a schematic plan view illustrating a partial internal structure of an electronic device 100 according to an embodiment of the present application. As shown in fig. 1, the electronic device 100 includes a metal frame 10, where the metal frame 10 is provided with a plurality of slots 11, the plurality of slots 11 divide the metal frame 10 into a plurality of independent frame sections 12, and the plurality of frame sections 12 serve as an antenna body and support frequency bands of a plurality of communication systems; at least three of the plurality of frame segments support a 5G frequency band, and at least one of the at least three frame segments supporting the 5G frequency band simultaneously supports an MHB frequency band of LTE, and outside the at least three frame segments supporting the 5G frequency band, at least one frame segment supports an MHB (medium-high frequency, Middle-high band) frequency band of LTE; the at least one frame segment supporting the MHB frequency band of the LTE, except 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 for realizing a 5G NSA communication system.

Therefore, in the application, at least one of the at least three frame segments supporting the 5G frequency band simultaneously supports the MHB frequency band of LTE, so that the number of antenna bodies can be reduced; and the 5G NSA communication system is realized by the at least one frame section supporting the MHB frequency band of LTE except the at least three frame sections supporting the 5G frequency band and the at least three frame sections supporting the 5G frequency band, and the 5G NSA communication system is realized mainly by a metal frame, so that the antenna performance is improved, and the cost is also reduced.

The frequency bands of the communication systems supported by the plurality of bezel segments 12 include frequency bands of communication systems such as 5G NSA (non-independent networking of 5 th generation communication technology), 5G SA (independent networking of 5 th generation communication technology), WIFI, GPS, and 2/3/4G (communication technology 2/3/4).

The aforementioned at least three frame segments support a 5G frequency band, which means that the at least three frame segments support a frequency band under a 5G NSA and/or 5G SA communication system. The MHB of the LTE refers to a medium-high frequency in a 4G LTE communication system.

In some embodiments, the at least one slit is opened at a portion of the metal bezel 10 located at the bottom end D1 of the electronic device 100.

Therefore, in the present application, the plurality of frame segments of the metal frame 10 are used as the antenna body to support the frequency bands under a plurality of communication systems including 5G NSA, 5G SA, WIFI, GPS and 2/3/4G, so as to meet the communication requirement, and the at least one slot is disposed at the bottom of the electronic device 100 of the metal frame 10, so as to reduce or avoid the slot at the bottom of the side of the electronic device 100 of the metal frame 10, thereby avoiding the influence caused by the user holding the metal frame in the using process.

The bottom end D1 of the electronic device 100 may be an end of the electronic device 100 that is located at a lower end when the electronic device 100 is placed right side. The top end D2 of the electronic device 100 is generally provided with a camera, the bottom end D1 is generally provided with a connection interface such as a USB interface, and the bottom end D1 of the electronic device 100 may be specifically one end provided with a connection interface such as a USB interface. That is, in the present application, at least one gap 11 is formed on the frame of the metal frame 10 on which the USB interface is formed.

As shown in fig. 1, the electronic device further includes a plurality of rf sources S1, wherein at least some of the bezel segments 12 are connected to an rf source S1, and the rf source S1 is configured to provide a feeding signal to at least some of the bezel segments, so as to excite the corresponding bezel segments 12 to operate, thereby implementing transceiving of rf signals in each frequency band under the multiple communication systems.

Different radio frequency sources S1 directly or indirectly excite the corresponding frame segments 12 to operate, so that each frame segment 12 operates in the corresponding frequency band under the corresponding communication system. For example, a certain rf source S1 may only directly excite a directly connected bezel segment 12, so that the bezel segment 12 operates to implement transceiving of rf signals in a corresponding frequency band under a corresponding communication system. For another example, another rf source S1 may directly excite the directly connected bezel segment 12, or indirectly excite the bezel segment adjacent to the directly connected bezel segment 12 through coupling feeding excitation, so that the bezel segment 12 and the adjacent bezel segment work together to implement transceiving of rf signals in the corresponding frequency band under the corresponding communication system.

As shown in fig. 1, in the present 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 correspondingly connected to at least one rf source S1. That is, in the present embodiment, each bezel segment 12 is connected to an RF source S1, and at least one RF source S1 is connected.

In the present application, the term "connected" includes direct connection and indirect connection, for example, a and B are connected, including a direct connection between a and B and an indirect connection between a and B through C.

An antenna device 200 (as shown in fig. 8) is formed by at least all the bezel segments 12 of the metal bezel 10 and the plurality of rf sources S1, that is, the antenna device 200 at least includes all the bezel segments 12 of the metal bezel 10 and the plurality of rf sources S1.

As shown in fig. 1, the electronic device 100 further includes a main board 20, and the antenna device 200 further includes an antenna body 21 disposed on the main board 20, where the antenna body 21 and a part of the bezel segment 12 cooperate to support a frequency band under one of the communication systems.

The antenna device 200 of the present application, outside the antenna body formed by the frame section of the metal frame 10, only needs to set one antenna body 21 on the main board 20, and can effectively improve the antenna performance compared with the existing scheme that needs to set a plurality of antenna bodies 21 on the main board 20. The antenna body 21 disposed on the main board 20 supports a high frequency band, and the antenna body 21 does not have a large influence on radiation performance even if located inside the electronic device 100 because of strong penetrability of the high frequency band.

The antenna body 21 may be an LDS antenna formed on an antenna support of the motherboard 20 by a laser technology, that is, the antenna support is disposed on the motherboard 20, and then the LDS antenna is formed thereon. The LDS antenna is a metal antenna pattern directly plated on an antenna support disposed on the motherboard 20 by a laser technology. In other embodiments, the antenna body 21 may also be an FPC (flexible printed circuit) antenna disposed on the main board 20. The FPC antenna refers to a metal antenna pattern formed on an FPC, and the FPC antenna may be fixed to the main board 20 by bonding, embedding, welding, or the like.

In some embodiments, at least one of the plurality of side frame bodies 12 individually supports a frequency band in a certain communication system, and at least some of the side frame bodies 12 cooperate with at least other side frame bodies to support the frequency band in the certain communication system.

The phrase "at least part of the side frame body 12 supports a frequency band under a certain communication system at least in cooperation with other side frame bodies" includes: the plurality of side frame bodies 12 support a frequency band in a certain communication system in a matching manner, or the plurality of side frame bodies 12 support a frequency band in a certain communication system in a matching manner with the antenna body 21 on the main board 20.

As shown in fig. 1, the antenna body 21 on the main board 20 is also connected to a radio frequency source S1, and the antenna body 21 operates under the excitation of the excitation signal of the radio frequency source S1 and works together with other corresponding bezel segments 12 to realize the transmission and reception of the radio frequency signal in the corresponding frequency band under the corresponding communication system.

As shown in fig. 1, the electronic device 100 is substantially square, the metal frame 10 is a rectangular frame, and includes 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 surround to form the metal frame 10. The portion of the metal frame 10 located at the bottom end of the electronic device 100 may be specifically a portion of one of the short frames 101 provided with a connection interface such as a USB interface.

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 102 b. 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.

Fig. 1 is a schematic view of an electronic device 100 viewed from a screen side, and the terms "top", "bottom", "left side" and "right side" are all directions viewed from the perspective of fig. 1.

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

As shown in fig. 1, 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 11 f.

That is, in the present embodiment, the metal frame 10 has 6 slits 11, and the metal frame is divided into six independent frame sections 12. Here, the independent frame segment 12 in this application means that the slit 11 completely divides and breaks the adjacent frame segments 12.

The

slits

11a and 11b formed in 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 formed in the first long frame 102a are both close to the first short frame 101a, and the slit 11d is closer to the first short frame 101a than the slit 11 e. The slit 11c formed in the second short frame 101b is disposed close to the first long frame 102a, and the slit 11f formed in the second long frame 102b is disposed close to the first short frame 101 a.

Therefore, in the present invention, the two

slits

11d and 11e opened in the first long frame 102a and the slit 11f opened in the second long frame 102b on the metal bezel 10 are both disposed close to the first short frame 101a, and therefore, the slit 11 is not opened at a position close to the bottom of the side of the electronic device 100. When a user holds the electronic device 100 vertically, the holding position is generally the position close to the bottom of the side of the electronic device 100, and since no gap is formed in the position, the holding of the user does not affect the radiation of the antenna. In the present application, the vertical holding of the electronic device 100 refers to a manner of holding the electronic device 100 when the electronic device 100 is placed in a vertical screen display state, and correspondingly, the horizontal holding of the electronic device 100 refers to a manner of holding the electronic device 100 when the electronic device 100 is placed in a horizontal screen display state.

Specifically, the six frame segments 12 include a first frame segment 12a located between the

slits

11a and 11b, a second frame segment 12b located between the

slits

slits

slits

The predetermined location B1 of the third frame segment 12c between the two rf sources S1 is grounded, so that 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 predetermined location B2 of the fourth frame segment 12d between the two rf sources S1 is also grounded, so as to effectively divide the fourth frame segment 12d into two antenna bodies, and the two rf sources S1 are respectively connected to the two antenna bodies.

The preset portion of the third frame segment 12c located between the two rf sources S1 is a partial portion of the third frame segment 12c located in the region between the two rf sources S1, and the two rf sources S1 and the preset portion of the third frame segment 12c grounded have a gap therebetween, so as to form a feeding loop respectively. The predetermined portion of the fourth frame segment 12d located between the two rf sources S1 is also a portion of the region located between the two rf sources S1, and the two rf sources S1 are spaced from the predetermined portion of the fourth frame segment 12d that is grounded to form a feeding loop.

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

Specifically, a portion of the third frame segment 12c located between the slot 11f and the ground (i.e., the predetermined grounded portion B1) constitutes a first antenna body ANT0, and a portion of the third frame segment 12c located between the slot 11c and the ground (i.e., the predetermined grounded portion B1) constitutes a second antenna body ANT 1. The first frame segment 12a forms a third antenna body ANT2, and a portion of the fourth frame segment 12d between the slot 11c and the ground (i.e., the predetermined portion B2 of the ground) forms a fourth antenna body ANT 3. The fifth frame segment 12e constitutes a fifth antenna body ANT4, and the second frame segment 12b constitutes a sixth antenna body ANT 5. The sixth frame segment 12f constitutes a seventh antenna body ANT 6. A portion of the fourth frame segment 12d between the slot 11e and the ground (i.e., the predetermined ground portion B2) constitutes an eighth antenna ANT 7.

In addition to the antenna body 21 located on the main board 20 as described above, in the present application, nine antenna bodies are formed by the metal bezel 10 and the antenna body 21 on the main board. That is, the antenna body 21 located on the main board 20 constitutes a ninth antenna body ANT8, and in this application, nine antenna bodies including ANT0 to ANT8 are actually formed.

The frequency bands supported by the first antenna body ANT0 are three frequency bands LB DRX + MHB MIMO2+ N41PRX, where LB refers to a low band (low band), MHB refers to a medium high band (middle high band), and N41 refers to an N41 frequency band in a 5G NSA communication system. That is, the frequency band supported by the first antenna body ANT0 is low frequency + medium-high frequency + N41. The LB DRX refers to a diversity antenna body of which the first antenna body ANT0 defaults to a low frequency band, and the N41PRX refers to a main diversity antenna body of which the first antenna body ANT0 defaults to an N41 frequency band. MHB MIMO2 refers to that the first antenna body ANT0 supports a multiple input multiple output (middle high band) antenna system in a medium-high frequency band.

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. Wherein, the LB PRX refers to the second antenna ANT1 default to the main set antenna of the low frequency band.

The frequency band supported by the third antenna ANT2 is MHB PRX + N78/N79 PRX, where N78/N79 refers to N78/N79 frequency band in 5G NSA communication system, that is, the frequency band supported by the third antenna ANT2 is medium-high frequency + N78/N79. The MHB PRX refers to a main set antenna body of the medium-high frequency band defaulted by the third antenna body ANT2, and the N78/N79 PRX refers to a main set antenna body of the N78/N79 frequency band defaulted by the third antenna body ANT 2.

The frequency bands supported by the fourth antenna ANT3 are: MHB DRX + N41MIMO2, i.e., the fourth antenna body ANT3 supports medium and high frequencies and the N41 band. The MHB DRX refers to a diversity antenna of a medium-high frequency band defaulted by the fourth antenna ANT3, and the N41MIMO2 refers to that the fourth antenna ANT3 supports MIMO antenna support in the N41 frequency band.

The frequency band supported by the fifth antenna ANT4 is MHB MIMO3+ N41 DRX + N78/N79DRX, that is, the frequency band supported by the fifth antenna ANT4 is a middle-low frequency + N41+ N78/N79 frequency band. The MHB MIMO3 indicates that the fifth antenna body ANT4 supports a MIMO antenna system in the medium-high frequency band, the N41 DRX indicates that the fifth antenna body ANT4 defaults to a diversity antenna of N41, and the N78/N79DRX indicates that the fifth antenna body ANT4 defaults to a diversity antenna of N78/N79.

The frequency band supported by the seventh antenna body ANT6 is GPS L1+ WIFI2.4G/5G + N41MIMO 3, namely, the frequency band supported by the seventh antenna body ANT6 is GPS L1 frequency band + WIFI2.4G/5G frequency band + N41 frequency band, and the seventh antenna body ANT6 supports a multi-input and output antenna system under N78/N79 frequency band.

The frequency of the GPS L1 is 1575MHz, the frequency range of the WIFI2.4G is 2.4-2.484MHz, and the frequency range of the WIFI 5G is 5.15-5.85 MHz.

The frequency band supported by the eighth antenna body ANT7 is ANT8: GPS L5+ WIFI 5G + WIFI2.4G, that is, the frequency band supported by the eighth antenna body ANT7 is a GPS L5 frequency band + WIFI2.4G frequency band + WIFI 5G frequency band.

The antenna body 21 on the motherboard 20 constitutes a ninth antenna body ANT8, and supports a frequency band N78/N79MIMO, that is, the frequency band supported by the antenna body 21 on the motherboard 20 is an N78/N79 frequency band in a 5G NSA communication system, and supports a multiple input and output antenna system in an N78/N79 frequency band.

Because the N78/N79 frequency band is a high frequency band and the requirement for the antenna space is relatively low, the antenna body 21 is arranged on the bracket of the main board 20, and the performance of the N78/N79 antenna can be better realized.

Therefore, the frequency bands supported by the nine antenna bodies in total realize a plurality of frequency bands including 5G NSA, 5G SA, WIFI, GPS and 2/3/4G.

As described above, the frequency bands supported by the first antenna body ANT0 are three frequency bands 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 support 2/3/4G communication system independently, that is, can work in 2/3/4G communication system independently, and realize the transceiving of radio frequency signals of 2/3/4G communication system.

The frequency band supported by the third antenna ANT2 is MHB + N78/N79, and the third antenna ANT2 supports 2/3/4G communication system alone, that is, the third antenna ANT2 can work in 2/3/4G communication system alone, so as to realize transceiving of radio frequency signals in 2/3/4G communication system. Wherein the third antenna ANT2 also supports the N78/N79 band. The frequency band supported by the fourth antenna ANT3 is MHB + N41MIMO2, and also supports the frequency band of 2/3/4G communication system alone and also supports the N41 frequency band.

As described above, the frequency band supported by the seventh antenna body ANT6 is GPS L1+ WIFI2.4G/5G + N41MIMO 3, the frequency band supported by the eighth antenna body ANT7 is ANT8: GPS L5+ WIFI 5G + WIFI2.4G, and the seventh antenna body ANT6 and the eighth antenna body ANT7 both support frequency bands in GPS and WIFI communication systems, that is, both can separately implement the transceiving of radio frequency signals in GPS and WIFI communication systems. Herein, both 4G and LTE in the present application refer to 4G LTE.

In this embodiment, the 5G NSA is specifically supported by 5 antenna bodies in a matching manner, and at least one of the 5 antenna bodies supports both LTE and 5G frequency bands. That is, the antenna architecture of the 5G NSA includes the above-mentioned 5 antenna bodies, and at least one of the 5 antenna bodies supports both LTE and 5G bands and supports dual bands.

Therefore, compared with the structure which needs six antennas under the existing 5G NSA communication system, the antenna structure can be reduced by one antenna body, the overall layout of the antennas is facilitated, the number of the antennas arranged on the main board 20 can be reduced, the cost is reduced, and the overall performance of the antennas is also improved.

Fig. 2 is a schematic plan view illustrating an antenna architecture of the N41 band of 5G NSA of the electronic device 100 according to an embodiment of the present application. In order to clearly illustrate the antenna architecture composition of the N41 frequency band of 5G NSA, fig. 2 is simplified, and some components are omitted compared with fig. 1.

Specifically, the N41 frequency band of the 5G NSA is cooperatively supported by a first antenna body ANT0, a third antenna body ANT2, a fourth antenna body ANT3, a fifth antenna body ANT4 and a seventh antenna body ANT 6. That is, the antenna architecture of the N41 band of the 5G NSA includes a first antenna body ANT0, a third antenna body ANT2, a fourth antenna body ANT3, a fifth antenna body ANT4, and a seventh antenna body ANT 6. In this embodiment, the fourth antenna ANT3 supports at least dual bands of LTE and N41 and may replace two existing antennas, the third antenna ANT2 supports an LTE frequency band, and the first antenna ANT0, the fifth antenna ANT4 and the seventh antenna ANT6 all support an N41 frequency band, so that two antennas supporting the LTE frequency band and 4 antennas supporting the N41 frequency band are realized by the five antennas, and the transmission and reception of radio frequency signals of the N41 frequency band of 5G NSA may be realized.

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 substantially arranged around the metal frame 10, so as to form a 5G antenna in a winding manner.

Obviously, in other embodiments, other antennas may support LTE and N41 dual bands, as long as at least one antenna body supports LET and N41 dual bands simultaneously.

Please refer to fig. 3, which is a schematic plan view illustrating an antenna structure of N78/N79 band of 5G NSA of the electronic device 100 according to an embodiment of the present application. Fig. 3 is also simplified for clarity of illustration, and some components are omitted from fig. 1.
