[0028] An embodiment of the present application provides an electronic device, the electronic device includes a multiple-input multiple-output MIMO antenna, and the MIMO antenna includes:

[0029] A first low-frequency antenna, wherein an antenna branch of the first low-frequency antenna is arranged on a metal decorative part of a camera of the electronic device;

[0030] Optionally, the antenna branch of the first low-frequency antenna may be a camera metal decorative piece directly set as the antenna branch; for example, the camera decorative piece is a metal piece, and the metal piece is used as the first low-frequency antenna of the present application.

[0031] A second low-frequency antenna, wherein an antenna branch of the second low-frequency antenna is arranged on a first portion of a metal frame on a first side of the electronic device;

[0032] a third low-frequency antenna, wherein antenna branches of the third low-frequency antenna are arranged on a metal frame between the second side edge and the bottom edge of the electronic device;

[0033] A fourth low-frequency antenna, wherein an antenna branch of the fourth low-frequency antenna is arranged on the second portion of the metal frame of the first side of the electronic device.

[0034] Optionally, the antenna branches mentioned in the embodiments of the present application may be understood as antenna radiators, antenna radiating units, etc., which are not listed one by one here.

[0035] Optionally, the antenna branch of the fourth low-frequency antenna is arranged adjacent to an end of the antenna branch of the second low-frequency antenna where a grounding point is arranged.

[0036] In one implementation, Figure 1 As shown, the antenna branch of the first low-frequency antenna is provided with: a feed source access point 17 and two grounding points.

[0037] Optionally, the current path length between the two grounding points is generally related to the wavelength λ corresponding to the resonant frequency, such as an integer multiple of 1 / 2λ (or 1 / 4λ), and is not specifically limited thereto.

[0038] The first low-frequency antenna provided in the embodiment of the present application can realize the function of a low-frequency receiving antenna while avoiding affecting adjacent medium- and high-frequency antennas and satellite antennas; the first low-frequency antenna is implemented using a camera metal decorative part, and due to the obstruction of the screen, it has a significant contribution (more than 20%) to the low-frequency sensitivity in the head-hand state.

[0039] In another implementation, Figure 1 As shown, a feed access point 14 and a grounding point are provided on the antenna branch of the second low-frequency antenna; it mainly carries the low-frequency power index design; optionally, the feed access point 14 can also be understood as a low-frequency feed and switch access point.

[0040] In another implementation, Figure 1 As shown, the antenna branch of the third low-frequency antenna is provided with a feed access point 9, two coordinated tuning switches 8 and a tuning switch 10. The antenna branch can be understood as an L-shaped section of the metal frame to which the feed access point 9 belongs, and a return point is provided in the middle area of ​​the length of the antenna branch. The third low-frequency antenna uses multiple switches for coordinated tuning and an adaptive tuning algorithm to optimize the performance of handheld and head-hand states. Compared with conventional inverted F antennas, the third low-frequency antenna uses a larger physical size, which significantly improves its efficiency and bandwidth. Optionally, the feed access point 9 can also be understood as a low-frequency feed and switch access point.

[0041] In another implementation, Figure 1 As shown, a feed access point 13 is provided on the antenna branch of the fourth low-frequency antenna. The fourth low-frequency antenna and the second low-frequency antenna are arranged on the same side of the electronic device (i.e., the first side), and the antenna end thereof corresponds to the grounding position of the second low-frequency antenna, so as to realize physical isolation between the two low-frequency antennas, and mainly realize the sensitivity improvement of low-frequency freedom, hand-held, and head-hand states. Optionally, the feed access point 13 can also be understood as a low-frequency feed and switch access point.

[0042] In at least one embodiment of the present application, the electronic device includes a housing;

[0043] The shell is provided with a through hole for accommodating a camera, and the camera metal decorative piece is arranged at the edge of the through hole.

[0044] In summary, the embodiment of the present application sets a low-frequency antenna on the metal decorative part of the camera of the electronic device, thereby realizing low-frequency 4*4 MIMO, which can enhance the signal receiving capability of the mobile electronic device under the low-frequency working state, thereby expanding the area where the electronic device accesses the cellular network (sensitivity is increased by 3dB, and the communication distance is increased by 50%) or improving the network speed in the area where the electronic device accesses the network (the better the signal quality received by the terminal, the higher the network speed can be obtained).

[0045] It should be noted that conventional cellular mobile communications rely on ground base stations as wireless access points. When a cellular mobile electronic device is in an area without ground base station cellular network services, the cellular mobile electronic device cannot maintain wireless communication with the outside world. In order to solve the above problem, the embodiment of the present application integrates the design of satellite communication antennas and systems based on the existing cellular antenna system, which can provide a new wireless communication method when the mobile electronic device is in an area without ground base station cellular network services. Specifically, Figure 1 As shown, in yet another optional embodiment of the present application, the electronic device further includes: a first medium and high frequency antenna;

[0046] The first medium and high frequency antenna includes: a first antenna branch where a first feed access point 1 is located, and a coupling branch of the first antenna branch, and the coupling branch of the first antenna branch is provided with a first tuning switch 2, a first satellite antenna feed access point 3, and a second satellite antenna feed access point 4.

[0047] Optionally, the first feed access point 1 can also be understood as a medium-high frequency and N78 feed and switch access point.

[0048] As an optional embodiment, the electronic device further includes:

[0049] a first switch, wherein a first end of the first switch is connected to a first satellite antenna feed and a second satellite antenna feed, a second end of the first switch is connected to the first satellite antenna feed access point 3, a third end of the first switch is connected to the second satellite antenna feed access point 4, and a fourth end of the first switch is connected to a ground point;

[0050] Wherein, in the first working state of the electronic device, the first switch grounds the first satellite antenna feed access point 3 and the second satellite antenna feed access point 4 through the fourth end;

[0051] Alternatively, in the second working state of the electronic device, the first switch connects the first satellite antenna feed to the first satellite antenna feed access point 3 via the second end;

[0052] Alternatively, in the second working state of the electronic device, the first switch connects the second satellite antenna feed to the second satellite antenna feed access point 4 through the third end.

[0053] In one implementation, the first switch is a single-pole multi-throw switch; in another implementation, the first switch is a plurality of independently arranged switches; no specific limitation is made here.

[0054] Optionally, the first working state of the electronic device can be understood as: the electronic device is in an area served by a ground base station cellular network and is in a working state served by a cellular antenna.

[0055] Optionally, the second working state of the electronic device can be understood as: the electronic device is in an area without ground base station cellular network service and is in a working state provided with service by a satellite antenna.

[0056] In one implementation, at the first tuning switch 2, a GPS L5 antenna feed signal access point is also provided. When the electronic device is in the first working state (i.e., non-satellite working state, which can also be referred to as a cellular network working state when the network signal is good), the switch at the first satellite antenna feed access point 3 and the switch at the second satellite antenna feed access point 4 are both switched to a short-circuit state to the ground, so as to achieve better isolation between the cellular (GPS / WIFI, first medium and high frequency antenna, L5) antennas. For example, in the absence of the switch at the second satellite antenna feed access point 4, the WIFI 2.4G performance of the antenna to which the fifth feed access point 5 belongs may be reduced by 3-dB, and the mutual influence between the antenna to which the fifth feed access point 5 belongs and the antenna to which the first feed access point 1 belongs increases; wherein, the fifth feed access point 5 is a fusion feed point for the WIFI and global positioning system GPS L1 frequency bands.

[0057] In the frequency band switching between L5 and medium and high frequency, when the medium and high frequency coupling branch first tuning switch 2 is implemented using capacitive tuning and a specific resonant circuit, the problem of stability of the L5 antenna resonant frequency in the medium and high frequency switching state can be avoided.

[0058] In the embodiment of the present application, the first medium and high frequency antenna structure is not designed with a SAR (Specific Absorption Rate) sensor high frequency return point, so the fourth medium and high frequency antenna adjacent thereto can be well isolated (not less than 13 dB). At the same time, since the radiation structure does not have a SAR sensor auxiliary circuit, its loss is low and the radiation efficiency is relatively high, thereby ensuring a good free and single-handed antenna efficiency of the first medium and high frequency antenna. Compared with the medium and high frequency antenna with a SAR sensor, its efficiency can be improved by 17%-25%.

[0059] The SAR sensor sensing device uses the change in capacitance between two pieces of metal to determine the proximity of a human body.

[0060] Optionally, the first satellite antenna feed access point 3 can be a Tiantong or Beidou antenna feed access point; the second satellite antenna feed access point 4 can be a Tiantong or Beidou antenna feed access point, which is not specifically limited here. The embodiment of the present application uses satellite communication as a supplement to cellular communication to meet ground emergency communication needs, such as geological disasters, outdoor extreme sports, and offshore areas.

[0061] In at least one embodiment of the present application, the electronic device further includes: a second medium and high frequency antenna, a third medium and high frequency antenna, and a fourth medium and high frequency antenna; wherein,

[0062] The second medium and high frequency antenna comprises: a second antenna branch where the second feed source access point 7 is located, and a coupling branch of the second antenna branch; a third tuning switch 8 is provided on the coupling branch of the second antenna branch;

[0063] The third medium and high frequency antenna comprises: a third antenna branch where a third feed access point 11 and a switch access point 12 are located, and a first coupling branch of the third antenna branch; a fourth tuning switch 10 is arranged on the first coupling branch of the third antenna branch;

[0064] The fourth medium and high frequency antenna includes: a fourth antenna branch where a fourth feed access point 15 is located, and a coupling branch of the fourth antenna branch, and a fifth tuning switch 14 and a sixth tuning switch 16 are respectively provided on the coupling branch of the fourth antenna branch.

[0065] The third medium and high frequency antenna further includes: a second coupling branch of the third antenna branch, and the second coupling branch is arranged between the fourth tuning switch 10 and the third feed access point 11.

[0066] like Figure 1 As shown, the second medium and high frequency antenna mainly realizes the supplement of receiving capability. Because of its dual narrow low frequency gap and its tuning switch arranged at the end of the low frequency breakpoint, its antenna bandwidth and efficiency are relatively insufficient. Designing it as a receiving antenna is conducive to improving the medium and high frequency MIMO capability. Optionally, the second feed access point 7 can also be understood as the medium and high frequency and N78 / 79 feed and switch access point.

[0067] Optionally, the third feed access point 11 can also be understood as a medium-high frequency feed access point, and the switch access point 12 can also be understood as a resonant branch switch access point; the third medium-high frequency antenna is mainly composed of a multi-coupling structure between the fourth tuning switch 10 and the switch access point 12. The breakpoint between the fourth tuning switch 10 and the third feed access point 11 can constitute the above-mentioned second coupling branch.

[0068] Optionally, the fourth feed access point 15 can be understood as a medium and high frequency and N78 / 79 feed and switch access point.

[0069] In at least one embodiment of the present application, the electronic device further includes: a first SAR sensor, a second SAR sensor, and a third SAR sensor; wherein,

[0070] The first SAR sensor is arranged on a coupling branch of the first antenna branch; or, the first SAR sensor is arranged on the first antenna branch;

[0071] The second SAR sensor is arranged on the second coupling branch of the third antenna branch;

[0072] The third SAR sensor is disposed on the fourth antenna branch.

[0073] In the embodiment of the present application, the layout position of the SAR sensor (i.e., the first SAR sensor) on the top of the electronic device includes two positions, namely:

[0074] 1) On the coupling branch of the first antenna branch where the first feed access point 1 is located, that is, the branch where the first tuning switch 2 or the first satellite antenna feed access point 3 or the second satellite antenna feed access point 4 is located; the first SAR sensor sensing device of the adjacent antenna multiplexing satellite antenna; to achieve the demand of head-to-hand call detection in the satellite state and to achieve appropriate power control. This SAR sensor is also the head sensing device of the first medium and high frequency antenna, so that the antenna to which the first feed access point 1 belongs can obtain relatively good handheld performance;

[0075] 2) On the antenna branch where the first feed access point 1 is located, the grounding between the two needs to be designed as high-frequency grounding; at this time, the SAR control device of the satellite antenna reuses the medium and high frequency antenna branches. In this position, the satellite antenna structure has no SAR sensor connection circuit, which can improve the satellite antenna gain compared to the structure of the satellite antenna including the SAR sensor connection circuit, such as the satellite antenna gain can be improved by 17%.

[0076] In the embodiment of the present application, a SAR sensor (ie, a second SAR sensor) is provided on the second coupling branch of the third antenna branch to realize human body sensing in the bottom area of ​​the electronic device, thereby realizing SAR reduction parameter control of the antenna.

[0077] In the embodiment of the present application, a SAR sensor (ie, the third SAR sensor) is provided on the fourth antenna branch, so that the SAR parameters of the adjacent antennas can be configured.

[0078] In summary, the embodiment of the present application sets SAR sensor structures on three sides of the electronic device to achieve human body sensing in three large areas (three sides of the electronic device), thereby realizing flexible configuration of the transmission power of multiple antennas.

[0079] like Figure 1 As shown, the electronic device provided in the embodiment of the present application also includes:

[0080] Two N79 antennas are set on the motherboard bracket. Figure 1 Area A and Area B shown;

[0081] The fourth N78 antenna is integrated into one of the WiFi antennas. 6 represents its integrated feed access point. The antenna branches are composed of a double-branch dual structure.

[0082] WIFI first antenna: 6 represents the WIFI and N78 fusion feed access point, and its antenna branches are composed of the metal frame of the feed access point and the coupling structure on the other side of the breakpoint;

[0083] WIFI second antenna: 5 represents the WIFI and GPS L1 fusion feed access point (i.e., the fifth feed access point), and its antenna branches are composed of the metal frame to which the feed access point belongs and the coupling structure on the other side of the breakpoint;

[0084] In at least one embodiment of the present application,

[0085] The coupling branch of the first antenna branch where the first feed access point 1 is located is the main branch of the satellite antenna;

[0086] The first antenna branch where the first feed access point 1 is located, and the antenna branch where the fifth feed access point 5 is located, are auxiliary branches of the satellite antenna;

[0087] The fifth feed access point 5 is a fusion feeding point of WIFI and global positioning system GPS L1 frequency band.

[0088] The main branch and auxiliary branch work together to achieve the satellite antenna design goal: the antenna pattern points to the dome. Because the satellite can provide better signal coverage in the dome area, the terminal's satellite antenna pattern also needs to point to this area to establish a good physical connection between the terminal and the satellite to ensure a smooth communication experience.

[0089] The branch where the first tuning switch 2 or the first satellite antenna feed access point 3 or the second satellite antenna feed access point 4 is located is the main branch of the antenna. This branch is also designed as a SAR sensor structure (there is no DC conduction path between the antenna metal and the terminal reference ground, and a high-frequency isolation inductor is set in the SAR sensor access circuit) to meet the needs of head-to-head communication detection in the satellite state and to achieve appropriate power control. This device is also a head sensing device for the first medium and high frequency antenna. The first satellite antenna feed access point 3 or the second satellite antenna feed access point 4 represents the Beidou antenna feed access point, and the feed switching can be achieved through a switch with a single-pole double-throw function; the switch to which the first satellite antenna feed access point 3 or the second satellite antenna feed access point 4 belongs is preset with a short-circuit branch of the cellular network state to achieve isolation between the top antennas.

[0090] Alternatively, the first satellite antenna feed access point 3 and the second satellite antenna feed access point 4 represent independent feed access points of Tiantong and Beidou antennas respectively, but their feeds need to be accessed through a switch with a series function. When one of the satellite modules is working, the other satellite communication module is disconnected from its RF circuit to reduce the adverse performance impact of the path load on the antenna in working state; under this structure, the Beidou antenna gain can be increased by more than 20%, because when Beidou is working, the Tiantong position switch not only disconnects its RF signal source path, but also forms a short circuit to the ground at the antenna branch access point, and the Beidou antenna can form an inverted F antenna structure.

[0091] The first feed access point 1 and the fifth feed access point 5 are gain auxiliary adjustment branches. When the satellite communication module is working, the access points where the first feed access point 1 and the fifth feed access point 5 are located are short-circuited to the ground through corresponding switches, which prevents the current from spreading to the two corner areas of the terminal. At this time, the current of the satellite antenna is concentrated in the antenna branch area, and its radiation pattern can obtain the maximum gain in the dome area, thereby obtaining a better circular polarization gain index.

[0092] In summary, the electronic device provided in the embodiment of the present application includes: a metal-shaped multi-frequency MIMO antenna and an antenna layout of a dual-frequency satellite mobile terminal, the MIMO antenna includes low-frequency 4*4, medium-high frequency 4*4, 5G NR N77 / 78 / 79 4*4, WIFI2.4G 2*2, WIFI 5G 2*2; it also includes a dual-frequency positioning antenna and a satellite (Beidou, Tiantong) communication antenna, thereby enhancing the signal receiving capability of the mobile electronic device in the low-frequency working state, thereby expanding the area where the electronic device accesses the cellular network or increasing the network speed in the area where the electronic device accesses the cellular network, and when the mobile electronic device is in an area without ground base station cellular network service, a satellite communication method can be provided.
