Description

Technical Field

[0001] This application belongs to the field of antenna technology, specifically relating to an electronic device. Background Technology

[0002] With the continuous development of antenna technology, its application in electronic devices is becoming increasingly widespread. Currently, electronic devices are equipped with antennas that perform multiple functions, such as L5 positioning antennas. However, due to the limited size of electronic devices, the space available for antenna installation is also limited. Therefore, the L5 positioning antenna often needs to be combined with other antennas, resulting in poor radiation performance for these combined antennas. Utility Model Content

[0003] This application aims to provide an electronic device that can solve the problem of poor radiation performance of the antenna in electronic devices.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] This application provides an electronic device, including: a cover, a through hole for mounting a camera module, and a metal decorative piece on the through hole, the metal decorative piece being electrically connected to a first feed source and a ground plane, wherein the frequency band of the first feed source is located in the L5 frequency band.

[0006] In the embodiments of this application, since both the first feed and the floor are electrically connected to the metal decorative element, the metal decorative element can be reused as the radiator of the L5 positioning antenna. That is, the first feed and the metal decorative element can constitute part of the L5 positioning antenna, thereby eliminating the need to combine the L5 positioning antenna with other antennas, reducing the influence of other antennas on the L5 positioning antenna, and enhancing the radiation performance of the L5 positioning antenna.

Furthermore, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0013] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0014] See Figure 1 , Figure 1 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application, such as... Figure 1 As shown, the electronic device includes: a cover 10, on which a through hole 11 is provided for mounting a camera module, and a metal decorative piece 20 is provided on the through hole 11. The metal decorative piece 20 is electrically connected to a first feed source 50 and a floor 40 respectively. The frequency band of the first feed source 50 is located in the L5 frequency band.

[0015] In one optional implementation, the aforementioned floor 40 can be understood as the motherboard of an electronic device. Optionally, the motherboard can be a printed circuit board (PCB). In another optional implementation, the aforementioned floor 40 can be understood as a grounding plate set inside the electronic device, that is, the aforementioned floor 40 is a specially set component for grounding.

[0016] In this embodiment, since both the first feed 50 and the floor 40 are electrically connected to the metal decorative element 20, the metal decorative element 20 can be reused as the radiator of the L5 positioning antenna. That is, the first feed 50 and the metal decorative element 20 can constitute part of the L5 positioning antenna, thus eliminating the need to combine the L5 positioning antenna with other antennas, reducing the influence of other antennas on the L5 positioning antenna, and enhancing the radiation performance of the L5 positioning antenna.

[0017] Since the first feed 50 operates in the L5 band (1176MHz ± 1MHz), and the antenna can be a GPS antenna (i.e., it can be called an L5 positioning antenna), separating the L5 positioning antenna from other antennas can enhance its positioning capability in multipath interference scenarios and improve its positioning accuracy. Alternatively, the first feed 50 may also include the N79 band, with a frequency range of 4.4GHz to 5.0GHz.

[0018] It should be noted that in this embodiment, the metal decorative part 20 is reused as the radiator of the L5 positioning antenna, which enables the L5 positioning antenna to obtain high radiation efficiency. Compared with the related technology of setting the radiator of the L5 positioning antenna on the frame of the electronic device, this embodiment can improve the radiation efficiency of the L5 positioning antenna by 3dB. Furthermore, since the radiator of the L5 positioning antenna is not combined with other antennas, while improving the radiation efficiency of the L5 positioning antenna, it can also reduce the insertion loss of the communication link of other antennas and enhance the communication performance of other antennas.

[0019] The cover 10 can also be referred to as the back plate. The material of the cover 10 is not limited here. Optionally, the cover 10 can be made of ceramic material, glass material or metal material.

[0020] The specific shape of the cross-section of the through hole 11 is not limited here. Optionally, the shape of the cross-section of the through hole 11 can match the shape of the cross-section of the camera module. When the cross-section of the camera module is circular, the shape of the cross-section of the through hole 11 can be circular; when the cross-section of the camera module is rectangular, the shape of the cross-section of the through hole 11 can be rectangular.

[0021] Optionally, the metal decorative piece 20 can be detachably connected to the through hole 11. Alternatively, when a camera module is installed in the through hole 11, the metal decorative piece 20 can be detachably connected to the camera module. The metal decorative piece 20 can enhance the aesthetics of the camera module and electronic device and improve the user experience.

[0022] It should be noted that the shape of the metal decorative part 20 can also be matched with the shape of the cross-section of the through hole 11 and the shape of the cross-section of the camera module, respectively.

[0023] As an optional implementation method, see [link to implementation details]. Figure 1 The metal decorative part 20 is a circular decorative part. The first feed source 50 is electrically connected to the first connection point 21 of the circular decorative part, and the floor 40 is electrically connected to the second connection point 22 of the circular decorative part. The line connecting the first connection point 21 and the second connection point 22 is the diameter of the circular decorative part.

[0024] The floor 40 is electrically connected to the second connection point 22 of the circular decorative piece, meaning that the circular decorative piece can be grounded through the second connection point 22.

[0025] In this embodiment, since the line connecting the first connection point 21 and the second connection point 22 is the diameter of the circular decorative piece, the distance between the first connection point 21 and the second connection point 22 on the circular decorative piece can be maximized, thereby further enhancing the radiation performance of the antenna.

[0026] As an optional implementation, the electronic device further includes a frame 30 connected to the cover 10. The frame 30 includes a first radiator 31, a second radiator 32, and a third radiator 33. The second radiator 32 is located between the first radiator 31 and the third radiator 33. A first break 301 is provided between the first radiator 31 and the second radiator 32, and a second break 302 is provided between the second radiator 32 and the third radiator 33. The second radiator 32 is electrically connected to the second feed source 51 and the first tuning switch 303, respectively. The third radiator 33 is electrically connected to the floor 40.

[0027] The first radiator 31 can be connected to the first grounding point 41 on the floor 40, that is, the first radiator 31 can be grounded through the first grounding point 41, and the first grounding point 41 can be connected to the middle position of the first radiator 31; the third radiator 33 can be connected to the second grounding point 42 on the floor 40, that is, the third radiator 33 can be grounded through the second grounding point 42, and the third radiator 33 can refer to the section of radiator in the frame 30 from the end near the second break 302 to the position connected to the second grounding point 42.

[0028] The frame 30 can be made of metal, and therefore the frame 30 can also be called a metal frame. This allows at least a portion of the frame 30 to be reused as a radiator for different antennas, reducing the number of components on the electronic device and also reducing the overall size of the electronic device.

[0029] The specific type of the first tuning switch 303 is not limited here. Optionally, the first tuning switch 303 can be a series tuning switch, or alternatively, the first tuning switch 303 can be a parallel tuning switch, or alternatively, the first tuning switch 303 can also be a series-parallel tuning switch.

[0030] Optionally, the second feed 51 can be a low-frequency feed, and the low-frequency band can refer to the frequency band between 700M and 960M. Since there is a first break 301 between the second radiator 32 and the first radiator 31, and a second break 302 between the second radiator 32 and the third radiator 33, the second radiator 32 can be called a floating radiator or a floating branch.

[0031] It should be noted that the antenna composed of the first radiator 31, the second radiator 32, the third radiator 33, the second feed 51 and the first tuning switch 303 in this embodiment can be referred to as a low-band (LB) antenna.

[0032] Optionally, the second feed 51 can be a mid-high frequency feed, and the mid-high frequency band can refer to the frequency band between 1.71 GHz and 2.69 GHz. In this case, the antenna composed of the first radiator 31, the second radiator 32, the third radiator 33, the second feed 51 and the first tuning switch 303 in this embodiment can be called a mid-high frequency band (MHB) antenna.

[0033] It should be noted that, optionally, the second feed 51 can simultaneously include a low-frequency feed and a mid-to-high-frequency feed, and can switch between the low-frequency feed and the mid-to-high-frequency feed according to the specific application scenario of the electronic device. Thus, since the second feed 51 can simultaneously include a low-frequency feed and a mid-to-high-frequency feed, the antenna composed of the first radiator 31, the second radiator 32, the third radiator 33, the second feed 51, and the first tuning switch 303 can be understood as a combined antenna of an LB antenna and an MHB antenna. This combined antenna can be called an LMHB combined antenna, and it can result in better radiation performance for the LMHB combined antenna.

[0034] In this embodiment of the application, since the frame 30 includes a first radiator 31, a second radiator 32 and a third radiator 33, it can be understood that at least a portion of the frame 30 is reused as the first radiator 31, the second radiator 32 and the third radiator 33, thereby reducing the size of the electronic device.

[0035] In addition, when the second feed 51 is a low-frequency feed, compared with the inverted-F antenna (IFA) in the prior art, the LB antenna in this embodiment uses a larger physical size, which significantly improves its efficiency and bandwidth, thereby optimizing the performance of the LB antenna when the electronic device is in handheld or head-and-hand communication mode.

[0036] As an optional implementation method, see [link to implementation details]. Figure 1 The second feed source 51 is electrically connected to the first end of the second radiator 32, and the first tuning switch 303 is electrically connected to the second end of the second radiator 32. The first end is located near the first break 301, and the second end is located near the second break 302.

[0037] In this embodiment, the second end of the second radiator 32 can be electrically connected to the floor 40 through the first tuning switch 303, that is, the second end of the second radiator 32 can be grounded through the first tuning switch 303, and the first tuning switch 303 can be a parallel tuning switch.

[0038] In this embodiment, the second feed source 51 is electrically connected to the first end of the second radiator 32, and the first tuning switch 303 is electrically connected to the second end of the second radiator 32. This allows the first tuning switch 303 to have a better tuning effect.

[0039] As another optional implementation, the first tuning switch 303 is electrically connected to the second end of the second radiator 32 and the third end of the third radiator 33, respectively, with both the second end and the third end located close to the second break 302.

[0040] In this embodiment, when the first tuning switch 303 is electrically connected to the second end of the second radiator 32 and the third end of the third radiator 33 respectively, it can be understood that the second radiator 32 can be electrically connected to the third radiator 33 through the first tuning switch 303, and both the second radiator 32 and the third radiator 33 can be grounded through the second grounding point 42. At this time, the first tuning switch 303 can be a series tuning switch. In this way, the tuning effect of the first tuning switch 303 can also be better, and the diversity of the connection methods between the first tuning switch 303 and the second radiator 32 is increased.

[0041] As an optional implementation method, see [link to implementation details]. Figure 1 The frame 30 includes a first side frame 3011, a second side frame 3012, and a third side frame 3013. The first side frame 3011 and the second side frame 3012 are disposed opposite to each other. The third side frame 3013 is located between the first side frame 3011 and the second side frame 3012, and the third side frame 3013 is connected to the first side frame 3011 and the second side frame 3012 respectively. The first radiator 31, the second radiator 32, and the third radiator 33 constitute at least a part of the first side frame 3011, and the second radiator 32 is located in the middle position of the first side frame 3011.

[0042] Optionally, in this embodiment, the second feed source 51 can be a medium-high frequency feed source, and the first radiator 31 can also be provided with a separate tuning switch, which can be called a medium-high frequency coupled radiator tuning switch.

[0043] In this embodiment, since the second radiator 32 is located in the middle of the first side frame 3011, that is, the second radiator 32 is far away from the top and bottom areas of the electronic device and can be located in the waist area of ​​the electronic device, the contact between the second radiator 32 and the user can be reduced. Compared with the method of setting the second radiator 32 in the top or bottom area of ​​the electronic device, this embodiment reduces the attenuation effect of the radiation of the second radiator 32 when the head is close to or the hand is holding the electronic device by more than 30%. As a result, the radiation performance of the second radiator 32 is better when the electronic device is in head-and-hand calling, gaming, handheld, and other scenarios, and the wireless communication experience of the second radiator 32 can be improved.

[0044] As an optional implementation method, see [link to implementation details]. Figure 1The second side frame 3012 includes a fourth radiator 34, and the third side frame 3013 includes a fifth radiator 35. The fourth radiator 34 is electrically connected to the third feed 52, the fourth feed 53 and the ground plane 40, respectively. The fifth radiator 35 is electrically connected to the fifth feed 54 and the ground plane 40, respectively. The third feed 52, the fifth radiator 35, the fourth radiator 34 and a portion of the first radiator 31 constitute a multiple-in-multiple-out (MIMO) antenna.

[0045] The location where the fourth radiator 34 is electrically connected to the floor 40 is not limited. Optionally, the location where the fourth radiator 34 is electrically connected to the floor 40 can be located in the middle of the fourth radiator 34. Alternatively, the location where the fourth radiator 34 is electrically connected to the floor 40 can be a position on the fourth radiator 34 adjacent to the connection position of the third feed source 52.

[0046] The portion of the first radiator 31 mentioned above may refer to the portion close to the second radiator 32.

[0047] Among them, the frequency band corresponding to the third feed 52 can be the N78 band, which can refer to the frequency band between 3300MHz and 3800MHz.

[0048] In this embodiment, the third feed 52, the fifth radiator 35, the fourth radiator 34, and a portion of the first radiator 31 constitute the first MIMO antenna. This can further enhance the radiation performance of the electronic device. When the frequency band corresponding to the third feed 52 is the N78 band, the first MIMO antenna can be referred to as the N78 antenna. At the same time, the N78 antenna can be separated from other antennas (such as the LB antenna and MHB antenna mentioned above), thereby enhancing the dual-SIM dual-pass communication performance of the electronic device.

[0049] As an optional implementation method, see [link to implementation details]. Figure 1 The electronic device also includes a bracket 70, which is disposed opposite to the cover 10. A twelfth radiator A is disposed on the bracket 70. The third feed source 52, the twelfth radiator A, the metal decorative piece 20, and the fourth radiator 34 constitute a second MIMO antenna.

[0050] The twelfth radiator A can be a radiator of an inverted F antenna, and the twelfth radiator A can be partially opposite to and spaced apart from the metal decorative piece 20.

[0051] It should be noted that the twelfth radiator A can also be electrically connected to the floor 40, thereby grounding the twelfth radiator A.

[0052] In this embodiment of the application, the frequency band corresponding to the third feed source 52 can be the N79 frequency band, which refers to the frequency band between 4.8 GHz and 4.9 GHz. Thus, the third feed source 52, the twelfth radiator A, the metal decorative part 20, and the fourth radiator 34 constitute the second MIMO antenna, and the above-mentioned second MIMO antenna can be referred to as the MIMO antenna corresponding to the N79 frequency band, thereby further enhancing the radiation performance of the electronic device.

[0053] As an optional implementation method, see [link to implementation details]. Figure 1 The fourth radiator 34 includes a third connection point 341, a fourth connection point 342, and a fifth connection point 343. The fourth connection point 342 is located between the third connection point 341 and the fifth connection point 343. The third feed source 52 is electrically connected to the third connection point 341. The floor 40 is electrically connected to the fourth connection point 342. The fourth feed source 53 is electrically connected to the fifth connection point 343.

[0054] The fourth connection point 342 is electrically connected to the floor 40, which can be understood as the fourth radiator 34 being grounded through the fourth connection point 342.

[0055] In this embodiment of the application, the portion of the fourth radiator 34 located between the third connection point 341 and the fourth connection point 342 can be a separate second sub-radiator 345, and the portion of the fourth radiator 34 located between the fourth connection point 342 and the fifth connection point 343 can be another separate first sub-radiator 344. That is, the fourth connection point 342 can divide the fourth radiator 34 into two separate sub-radiators, the second sub-radiator 345 and the first sub-radiator 344. The radiation frequency bands of the second sub-radiator 345 and the first sub-radiator 344 can be the same or different, which can further enhance the radiation performance of the electronic device.

[0056] It should be noted that, optionally, see [link to relevant documentation]. Figure 1 The portion of the fourth radiator 34 located between the fourth connection point 342 and the fifth connection point 343 is the first sub-radiator 344. The electronic device also includes an eighth radiator 38, which has a third break 304 with the first sub-radiator 344. The eighth radiator 38 serves as a parasitic antenna of the first sub-radiator 344. The eighth radiator 38 can be electrically connected to the third grounding point 43 on the floor 40, i.e., the eighth radiator 38 can be grounded through the third grounding point 43. The eighth radiator 38 is electrically connected to the third tuning switch 61.

[0057] The frequency band corresponding to the fourth feed 53 may include at least one of the mid-high frequency band, the N78 frequency band, and the N79 frequency band.

[0058] In this embodiment, when the frequency band corresponding to the fourth feed 53 includes the mid-high frequency band, the antenna composed of the eighth radiator 38 and the first sub-radiator 344 can be called a mid-high frequency antenna. The mid-high frequency antenna can reuse the third tuning switch 61 to achieve the tuning of the mid-high frequency antenna. The mid-high frequency antenna in this embodiment can supplement the receiving capability of the antenna of the electronic device. Because the mid-high frequency antenna has a narrow low-frequency gap, and the third tuning switch 61 can be set at the end of the eighth radiator 38, that is, the third tuning switch 61 can be set adjacent to the connection point connected to the third grounding point 43, its antenna bandwidth and efficiency are relatively insufficient. Designing it as a simple receiving antenna is beneficial to improving the mid-high frequency MIMO capability.

[0059] It should be noted that, optionally, the eighth radiator 38 can also be electrically connected to a low-frequency feed source to form a separate low-frequency antenna. This low-frequency antenna can be mainly used in low-frequency head and handheld scenarios to improve the radiation performance of electronic devices in the above scenarios.

[0060] As an optional implementation method, see [link to implementation details]. Figure 1 The electronic device further includes a ninth radiator 39, a tenth radiator 310, and an eleventh radiator 311. The tenth radiator 310 is located between the ninth radiator 39 and the eleventh radiator 311, and there is a break between the tenth radiator 310 and both the ninth radiator 39 and the eleventh radiator 311. The tenth radiator 310 is electrically connected to the eighth feed source 57 and the floor 40, respectively, and the eleventh radiator 311 is electrically connected to the fourth tuning switch 62.

[0061] The ninth radiator 39 can be electrically connected to the fourth grounding point 44 on the floor 40, thereby grounding the ninth radiator 39; while the eleventh radiator 311 can be electrically connected to the fifth grounding point 45 on the floor 40, thereby grounding the eleventh radiator 311.

[0062] The ninth radiator 39 can be arranged adjacent to the eighth radiator 38, and the eleventh radiator 311 can be arranged adjacent to the third radiator 33. Optionally, the ninth radiator 39 can be connected to the eighth radiator 38, and the eleventh radiator 311 can be connected to the third radiator 33.

[0063] The tenth radiator 310 can be a floating radiator, meaning that the radiator is not directly grounded but is grounded through other components. Optionally, when the floating radiator is used as a parasitic radiator of other antennas (also called a coupled radiator) or connected to a printed circuit board, it can be grounded through other antennas or the printed circuit board. In this embodiment, the tenth radiator 310 can be used as the first coupled radiator of the eighth radiator 38, and the eleventh radiator 311 can be used as the second coupled radiator of the eighth radiator 38. Optionally, the ninth radiator 39, the tenth radiator 310, and the eleventh radiator 311 can all be at least a part of the fourth side frame 3014 of the frame 30, and the fourth side frame 3014 can be arranged opposite to the third side frame 3013 and connected to the first side frame 3011 and the second side frame 3012, respectively.

[0064] In this embodiment, the frequency band corresponding to the eighth feed 57 can be the mid-to-high frequency band, while the ninth radiator 39, the tenth radiator 310 and the eleventh radiator 311 can constitute the radiators of the mid-to-high frequency antenna, thereby further increasing the number of mid-to-high frequency antennas and further enhancing the radiation performance of the electronic device. The fourth tuning switch 62 is electrically connected to the eleventh radiator 311, thereby adjusting the radiation bandwidth of the mid-to-high frequency antenna.

[0065] As an optional implementation method, see [link to implementation details]. Figure 1 The electronic device further includes a sixth radiator 36, which is located at the connection between the second side frame 3012 and the third side frame 3013. The sixth radiator 36 is electrically connected to the sixth feed 55. The first part 351 of the fifth radiator 35 is a parasitic antenna of the sixth radiator 36. The first part 351 is the portion of the fifth radiator 35 between the position where it is connected to the floor 40 and the end near the sixth radiator 36. The first part 351 is electrically connected to the second tuning switch 60.

[0066] Optionally, the middle position of the fifth radiator 35 can be electrically connected to the eighth grounding point 48 and the ninth grounding point 49 on the floor 40, respectively. The radiator on the fifth radiator 35 between the position connected to the eighth grounding point 48 and the end near the sixth radiator 36 can be understood as the first part 351 mentioned above. The radiator on the fifth radiator 35 between the position connected to the ninth grounding point 49 and the end near the seventh radiator 37 mentioned later can be understood as the second part 352.

[0067] It should be noted that, optionally, the eighth grounding point 48 and the ninth grounding point 49 can be two separate nodes; alternatively, the eighth grounding point 48 and the ninth grounding point 49 can also be the same grounding point, and no specific limitation is made here.

[0068] The sixth feed 55 can be a mid-to-high frequency feed, and the second tuning switch 60 can be used for electrical length tuning to switch the MHB operating frequency band. Optionally, the sixth radiator 36 can be a floating radiator, that is, a floating radiator can be understood as a radiator that is not directly grounded, but when it is a parasitic radiator of other radiators or connected to a printed circuit board, it can be grounded through other antennas or printed circuit boards. Alternatively, the sixth radiator 36 can also be directly electrically connected to the sixth grounding point 46 and the seventh grounding point 47 on the ground 40. This can make the grounding effect of the sixth radiator 36 more stable. The sixth grounding point 46 can be connected to the middle position of the sixth radiator 36, and the seventh grounding point 47 can be connected to the position of the sixth radiator 36 near the fourth radiator 34.

[0069] Optionally, the sixth radiator 36 may have a break between it and the fifth radiator 35 and the fourth radiator 34, and the sixth radiator 36 may be an antenna for a sensor used to detect specific absorption rate (SAR). That is, the electromagnetic radiation energy absorbed by the human body can be detected by the sixth radiator 36, which can be used to assess the electromagnetic radiation safety of electronic devices.

[0070] In this embodiment of the application, since the electronic device also includes a sixth radiator 36, the radiation performance of the electronic device can be further enhanced.

[0071] It should be noted that the sixth radiator 36 can be tuned using the tuning switch (i.e., the second tuning switch 60) on the fifth radiator 35 to improve the radiation performance of the MHB antenna in single-frequency operation, or to improve the radiation performance of the MHB antenna in combination with GPS, WIFI, and N78.

[0072] It should be noted that the switches connected to the seventh radiator 37, the sixth radiator 36, the fifth radiator 35, and the fifth radiator 35 can be controlled by a communication arbitration controller and related algorithms, thereby improving the accuracy of controlling the switches.

[0073] As an optional implementation method, see [link to implementation details]. Figure 1 The second side frame 3012 includes a portion of the sixth radiator 36, and the third side frame 3013 includes another portion of the sixth radiator 36.

[0074] In this embodiment of the application, since the second side frame 3012 includes a part of the sixth radiator 36 and the third side frame 3013 includes another part of the sixth radiator 36, the sixth radiator 36 can be located at the corner of the second side frame 3012 and the third side frame 3013, thereby making the radiation performance of the sixth radiator 36 better.

[0075] As an optional implementation method, see [link to implementation details]. Figure 1 The electronic device further includes a seventh radiator 37, which is located at the connection between the first side frame 3011 and the third side frame 3013. The seventh radiator 37 is electrically connected to the seventh feed 56. The second part 352 of the fifth radiator 35 is a parasitic antenna of the seventh radiator 37. The second part 352 is the portion of the fifth radiator 35 between the position where it is connected to the floor 40 and the end near the seventh radiator 37.

[0076] The seventh radiator 37 can be electrically connected to the tenth grounding point 410 and the eleventh grounding point 411 on the floor 40, thereby grounding the seventh radiator 37. The tenth grounding point 410 can be electrically connected to the middle position of the seventh radiator 37, and the eleventh grounding point 411 can be electrically connected to the position of the seventh radiator 37 near the first radiator 31.

[0077] Among them, the seventh feed 56 can be the feed corresponding to the positioning system. Optionally, the frequency band corresponding to the seventh feed 56 can be the frequency band corresponding to the Beidou system. The transmitting frequency band corresponding to the Beidou system can be 1615.68±7MHz, and the polarization mode of the electromagnetic wave can be left-hand circular polarization during transmission. The receiving frequency band can be 2491.75±5MHz, and the polarization mode of the electromagnetic wave can be right-hand circular polarization during reception.

[0078] Alternatively, the frequency band corresponding to the seventh feed 56 can be the GPS-WIFI 2.4G frequency band, and the WIFI 2.4G frequency band can be 2400M-2500M.

[0079] In this embodiment, since the electronic device also includes a seventh radiator 37, the radiation performance of the electronic device can be further enhanced. In addition, when the seventh feed 56 is the feed corresponding to the positioning system, the antenna pattern of the radiator composed of the seventh radiator 37 and the second part 352 of the fifth radiator 35 can point to the dome. This is because the satellite can provide better signal coverage in the dome area, so the satellite antenna pattern of the electronic device also needs to point to this area so that the electronic device can establish a good physical connection with the satellite and ensure a smooth communication experience.

[0080] It should be noted that the positioning antenna, which consists of the second part 352 of the fifth radiator 35 and the seventh radiator 37, can be tuned by the second tuning switch 60 when transmitting (TX) or receiving (RX) signals to maximize the positioning antenna gain.

[0081] Optionally, the second part 352 can be connected to the fifth feed 54, and the frequency band corresponding to the fifth feed 54 can include the WIFI 5G frequency band and the N78 frequency band. In this way, the seventh radiator 37 can also be used as a parasitic antenna of the second part 352, and the combination of the seventh radiator 37 and the second part 352 can be combined to form the radiator of the first WIFI antenna.

[0082] Optionally, the first radiator 31 can also be electrically connected to the twelfth grounding point 412 on the floor 40. The twelfth grounding point 412 can be electrically connected to the position of the first radiator 31 near the seventh radiator 37. It should be noted that the radiator between the position where the twelfth grounding point 412 is connected to the first radiator 31 and the end of the first radiator 31 near the seventh radiator 37 can be understood as the third sub-radiator 3101. The third sub-radiator 3101 can be electrically connected to the ninth feed 58, and the frequency band corresponding to the ninth feed 58 can... Including the WIFI band and the N78 band, at least a portion of the seventh radiator 37 can serve as a parasitic antenna of the third sub-radiator 3101, and at least a portion of the seventh radiator 37 and the third sub-radiator 3101 can be combined to form the radiator of the second WIFI antenna. Optionally, the at least a portion of the seventh radiator 37 serving as a parasitic antenna of the third sub-radiator 3101 can be understood as the radiator from the end of the seventh radiator 37 near the third sub-radiator 3101 to the position electrically connected to the eleventh grounding point 411.
