Therefore, in the application, at least one frame section simultaneously supports the LMHB frequency band of LTE, at least one frame section supporting the LMHB frequency band of LTE and at least three frame sections supporting the 5G frequency band outside the at least three frame sections supporting the 5G frequency band are used for realizing the 5G NSA communication system, the number of antenna bodies can be reduced, the 5G NSA communication system is realized mainly through a metal frame, the antenna performance is improved, and the cost is also reduced. In addition, at least one frame section supporting the LMHB frequency band of LTE outside the at least three frame sections supporting the 5G frequency band and the frame sections simultaneously supporting the LMHB frequency band of LTE in the at least three frame sections supporting the 5G frequency band are respectively positioned on different sides of the metal frame, so that the antenna performance can be ensured by a user in different holding modes.
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 LMHB of the LTE refers to low, medium and high frequency under a 4G LTE communication system.
Wherein some of the plurality of bezel segments 12 are connected to the rf source S1 and at least one of the bezel segments 12 is not connected to the rf source S1.
In this application, a plurality of frame segments of the metal frame 10 are used as antenna bodies to support frequency bands of a plurality of communication systems including 5G NSA, 5G SA, WIFI, GPS, 2/3/4G, and the like, thereby satisfying communication requirements and minimizing the number of antennas arranged inside the device, and in addition, a part of the frame segments 12 of the plurality of frame segments 12 are connected with the rf source S1, at least one of the frame segments 12 is not connected with the rf source S1, the frame segment 12 not connected with the rf source S1 is coupled with the adjacent frame segment 12 connected with the rf source S1, and the number of the rf sources can be reduced as a reinforced antenna body or a parasitic antenna body of the antenna body formed by the frame segments connected with the rf source, thereby improving antenna performance or increasing antenna frequency bands.
Wherein the frame segment 12 not connected with the rf source S1 is grounded, and the frame segment 12 not connected with the rf source S1 is coupled with the adjacent frame segment 12 connected with 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 with the rf source.

As described above, a certain rf source S1 may only directly excite the 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.

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.

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.

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, in some embodiments, at least one gap is opened at a portion of the metal bezel 10 located at the bottom end D1 of the electronic device 100.
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.
Therefore, at least one slit is formed in the bottom end of the electronic device 100 of the metal frame 10, so that the slit at the bottom end of the side edge of the electronic device 100 of the metal frame 10 can be reduced, and the influence caused by holding by a user in the using process can be reduced.
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. That is, the metal frame 10 includes a first short frame 101a and a second short frame 101b opposite to each other, and a first long frame 102a and a second long frame 102b 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.
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 the present embodiment, the first short frame 101a has three slits 11a, 11b and 11c, the second short frame 101b has one slit 11d, the first long frame 102a has two slits 11e and 11f, and the second long frame 102b has three slits 11g, 11h and 11 i.
That is, in the present embodiment, the metal frame 10 has 9 slits 11, and the metal frame is divided into nine 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 11c formed in 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 11 a. Two gaps 11e and 11f formed in the first long frame 102a are both disposed near the first short frame 101a, and the gap 11e is closer to the first short frame 101a than the gap 11 f. A gap 11d formed in the second short frame 101b is disposed close to the first long frame 102a, a gap 11g formed in the second long frame 102b is disposed close to the first short frame 101a, gaps 11h and 11i formed in the second long frame 102b are both disposed close to the second short frame 101b, and the gap 11i is closer to the second short frame 101b than the gap 11 h.
Therefore, in the present invention, the two slits 11e and 11f opened in the first long frame 102a and the slit 11g 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 left side of the electronic device 100. When a user erects the electronic device 100, the holding position is generally the position of the side edge of the electronic device 100 close to the bottom, and since the gap 11 is not formed at the position of the left side edge close to the bottom, the influence of the holding of the user on the antenna radiation is reduced. 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 nine frame segments 12 include a first frame segment 12a located between the slits 11b and 11c, a second frame segment 12b located between the slits 11c and 11g, a third frame segment 12c located between the slits 11g and 11h, a fourth frame segment 12d located between the slits 11h and 11i, a fifth frame segment 12e located between the slits 11i and 11d, a sixth frame segment 12f located between the slit 11d and the slit 11f, a seventh frame segment 12g located between the slits 11f and 11e, an eighth frame segment 12h located between the slit 11e and the slit 11a, and a ninth frame segment 12i located between the slit 11a and the slit 11 b.
The first frame segment 12a, the third frame segment 12c, the fourth frame segment 12d, the fifth frame segment 12e, the sixth frame segment 12f, the seventh frame segment 12g, the eighth frame segment 12h, and the ninth frame segment 12i are all connected to one rf source S1, and the second frame segment 12b is not connected to the rf source S1.
That is, in the present embodiment, the second bezel segment 12b is not connected to the rf source S1, and the other bezel segments 12 are each connected to the corresponding rf source S1 one by one.
The non-end portion 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.
The non-end portion of the second frame segment 12B is grounded at a predetermined position B0, and the predetermined position B0 between the second frame segment 12B and the end of the third frame segment 12c is grounded at a predetermined position. Thus, the second frame section 12b has two ground points thereon.
Fig. 2 is a schematic plan view of the electronic device 100 illustrating each antenna. Fig. 2 is simplified for clarity of illustration, and some components and reference numerals are omitted from fig. 1.
The fourth frame segment 12d, the seventh frame segment 12g, the eighth frame segment 12h and the ninth frame segment 12i respectively form an antenna body; the sub-frame segment 121f connected with the radio frequency source S1 forms an antenna body; the first frame segment 12a is coupled to the second frame segment 12B, and an antenna body is formed between the first frame segment 12a and the preset grounding position B0 of the second frame segment 12B; the third frame segment 12c is also coupled to the second frame segment 12B, and an antenna body is also formed between the third frame segment 12c and the predetermined portion B0 of the second frame segment 12B, which is grounded; the fifth frame segment 12e is coupled to the sub-frame segment 122f of the sixth frame segment 12f, and the fifth frame segment 12e and the sixth frame segment 12f also form an antenna body.

As described above, the frequency band supported by the first antenna body ANT0 is a frequency band LMHB PRX, and the frequency band supported by the second antenna body ANT1 is LMHB DRX + N41DRX MIMO; therefore, the first antenna body ANT0 and the second antenna body ANT1 each support 2/3/4G communication system independently.
Therefore, when the electronic device 100 is in a network state of a 4G communication system, an antenna pair is formed between the first antenna body ANT0 and the second antenna body ANT1, and the main set and the diversity can be switched according to the strength of a signal.
As shown in fig. 1 and 7, since the first antenna body ANT0 is located on the second long rim 102b and the second antenna body ANT1 is located on the second short rim 101b, at least one of the first antenna body ANT0 and the second antenna body ANT1 is not held by a user and a signal is good regardless of whether the user holds the electronic device 100 in a horizontal or vertical manner. At this time, the main set and the diversity are switched according to the signal strength, and the signal quality of the LB frequency band of 2/3/4G can be ensured no matter the user holds the signal horizontally or vertically.

Therefore, the third antenna ANT2 and the fourth antenna ANT3 both support the N41 frequency band, and when the electronic device 100 is in the network state of the 5G NSA or 5G SA communication system, for the N41 frequency band, an antenna pair is formed between the third antenna ANT2 and the fourth antenna ANT3, so that the main set and the diversity can be switched according to the strength of the signal.
As shown in fig. 1 and 8, 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, at least one of the third antenna body ANT2 and the fourth antenna body ANT3 is not held by the user regardless of whether the user holds the third antenna body ANT or the fourth antenna body ANT3 horizontally or vertically, and the signal is good. At this time, for the N41 frequency band, the first antenna body ANT0 and the fifth antenna body ANT4 switch between the main set and the diversity according to the signal strength, so as to ensure the signal quality of the N41 frequency band of the 5G NSA communication system.
Please refer to fig. 9, which is a schematic diagram illustrating switching of an antenna supporting a 5G N78/N79/N77 band in the electronic device 100 of the present application. Fig. 9 is also simplified for clarity of illustration, and some components are omitted from fig. 1.

Similarly, whether the user holds the mobile terminal horizontally or vertically, at least one of the third antenna body ANT2, the fifth antenna body ANT4 and the sixth antenna body ANT5 is not held by the user, and the signal is good. At this time, for the N78/N79/N77 frequency band, the third antenna ANT2, the fifth antenna ANT4 and the sixth antenna ANT5 switch the main set and the diversity according to the strength of the signal, so as to ensure the signal quality of the N78/N79/N77 frequency band of the 5G NSA communication system.
For an antenna group including more than two antenna bodies, the strongest antenna body may be selected as a main set, and the other antenna bodies may be selected as a 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 may be selected as the main set, and the others may be selected as the diversity.
Wherein, the range of the N41 frequency band is 2.5-2.69GHz, the range of the N78 frequency band is 3.3-3.8GHz, and the range of the N79 frequency band is 4.8-5 GHz.

The rf processing circuit 400 is connected to the signal detector 300, and is configured to perform switching control on each pair of antenna bodies capable of switching between the main set and the diversity according to the signal strength detected by the signal detector 300.
Specifically, the rf processing circuit 400 determines, according to the signal strength detected by the signal detector 300, that the difference between the signal strengths 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 lower signal strength is the main set, controls to switch the antenna body with lower signal strength to the diversity, and controls to switch the antenna body with higher signal strength to the main set.
Wherein the preset threshold may be 6 db.
For example, for an antenna pair of the first antenna ANT0 supporting an LMHB PRX band and the second antenna ANT1 supporting an LMHB DRX + N41DRX MIMO band, the rf processing circuit 400 controls to switch the first antenna ANT0 to a main set and the second antenna ANT1 to a diversity set according to that the signal strength of the first antenna ANT0 detected by the signal detector 300 is greater than the signal strength of the second antenna ANT1, and a difference between the signal strength of the first antenna ANT 3526 and the signal strength of the second antenna ANT1 exceeds a preset threshold and the first antenna ANT0 is a diversity antenna.
