[0002] With the development of communication technology, electronic devices such as smartphones can realize more and more functions, and the communication modes of electronic devices are also more diversified. Each communication mode requires a corresponding antenna to support it. The performance of the antenna will directly determine the communication quality and the user experience.

[0003] However, factors such as the user's hand-holding posture and the folding form of the electronic device can easily affect the antenna performance of the electronic device. Therefore, it is urgent to provide an antenna solution that is less affected by factors such as the user's hand-holding posture and the folding form of the electronic device.

[0007] A second body, comprising a second short frame, another part of the first long frame and another part of the second long frame, wherein the second body can be folded or unfolded relative to the first body, so that the first short frame overlaps with the second short frame in a folded state, and the length of the first short frame or the second short frame in the unfolded state is less than the length of the first long frame or the second long frame;

[0008] A first radiator is arranged on the first short frame, the first radiator comprising a first end, a first feeding point, a first grounding point, a second grounding point, a second feeding point and a second end which are arranged in sequence;

[0029] The following will be combined with the attached examples of the present application Figure 1 To Attachment Fig.14 , the technical solutions in the embodiments of the present application are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0030] The embodiment of the present application provides an electronic device 10, which can be a smart phone, a tablet computer, or a gaming device, an augmented reality (AR) device, an automotive device, a data storage device, an audio playback device, a video playback device, a laptop computer, a desktop computing device, etc. The electronic device 10 has a wireless communication function. For example, the electronic device 10 can transmit wireless fidelity (Wi-Fi) signals, global positioning system (GPS) signals, third-generation mobile communication technology (3rd-Generation, 3G), fourth-generation mobile communication technology (4th-Generation, 4G), fifth-generation mobile communication technology (5th-Generation, 5G), near field communication (NFC) signals, Bluetooth (BT) signals, ultra-wideband communication (UWB) signals, etc.

[0031] Among them, please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a first structure of an electronic device 10 provided in an embodiment of the present application. Figure 2 for Figure 1 The electronic device 10 is a partial structural diagram of the electronic device 10. The electronic device 10 includes a middle frame 400, a first radiator 110, a first feed source 121 and a second feed source 122.

[0032] The middle frame 400 includes a first long frame 410 and a second long frame 420 that are arranged opposite to each other, and a first short frame 430 and a second short frame 440 that are arranged opposite to each other. The first radiator 110 is arranged on the first short frame 430, and the first radiator 110 includes a first end 111, a first feeding point 112, a first grounding point 113, a second grounding point 114, a second feeding point 115 and a second end 116 that are arranged in sequence, so that a first radiating section 117 can be formed between the first end 111 and the first grounding point 113, and a second radiating section 118 can be formed between the second end 116 and the second grounding point 114. The first radiator 110 may include the first radiating section 117, the second radiating section 118 and a radiating section between the two grounding points. The first feed source 121 is directly or indirectly electrically connected to the first feed point 112, and the first feed source 121 is used to stimulate the first radiation section 117 between the first end 111 and the first grounding point 113 to support the first positioning signal, or the first feed source 121 is used to stimulate the first radiation section 117 to support the first positioning signal and the first Wi-Fi signal at the same time. The second feed source 122 is directly or indirectly electrically connected to the second feed point 115, and the second feed source 122 is used to stimulate the second radiation section 118 between the second end 116 and the second grounding point 114 to support the second positioning signal.

[0033] It can be understood that the middle frame 400 can be a hollow frame structure or a thin plate structure, and the middle frame 400 is used to provide support for the electronic devices or functional components in the electronic device 10, so as to install the electronic devices and functional components of the electronic device 10 together. For example, the middle frame 400 can be provided with structures such as grooves, protrusions, through holes, etc., so as to facilitate the installation of the electronic devices or functional components of the electronic device 10. Among them, the first long frame 410, the first short frame 430, the second long frame 420 and the second short frame 440 of the middle frame 400 can be sequentially connected into a rectangular structure and form the outer frame of the electronic device 10, the first long frame 410 and the second long frame 420 can be extended along the first direction H1, the first short frame 430 and the second short frame 440 can be arranged along the second direction H2, and the length of the first long frame 410 and the second long frame 420 along the first direction H1 can be greater than the length of the first short frame 430 and the second short frame 440 along the second direction H2. The second direction H2 may be perpendicular to the first direction H1. When the first direction H1 is the length direction of the electronic device 10, the second direction H2 may be the width direction of the electronic device 10. Figure 1 As shown, the first short frame 430 may be the top frame of the electronic device 10 in the vertical position, and the second short frame 440 may be the bottom frame of the electronic device 10 in the vertical position. The first short frame 430 is set toward the sky when the electronic device 10 is in the vertical position, and the second short frame 440 is set toward the ground when the electronic device 10 is in the vertical position. Figure 1The posture shown is held vertically by the user. When in the vertical holding posture, the user's hand can easily hold the first long frame 410 and the second long frame 420 of the electronic device 10 but cannot easily hold the first short frame 430 .

[0034] It is understandable that when the first short frame 430 of the middle frame 400 includes a metal structure, the first short frame 430 may be, but is not limited to, formed by slits to form metal branches, and the first radiator 110 may include the metal branches, so that the first radiator 110 may be formed on the first short frame 430. Of course, when the first short frame 430 of the middle frame 400 does not include a metal structure, the first radiator 110 may also be provided on the first short frame 430 in the form of an in-mold injection (Mode Decor Antenna, MDA) antenna. It should be noted that the first radiator 110 may also be provided on the first short frame 430 in other forms, and the embodiment of the present application does not limit the specific manner in which the first radiator 110 is provided on the first short frame 430.

[0035] It can be understood that the first end 111 and the second end 116 of the first radiator 110 can be two free ends or open sections or ends of the first radiator 110, and the electronic device 10 can also include a ground plane 130, and the first ground point 113 and the second ground point 114 can be directly or indirectly electrically connected to the ground plane 130 and grounded, so that the first radiation section 117 between the first end 111 and the first ground point 113 can form a radiation structure, and the second radiation section 118 between the second end 116 and the second ground point 114 can form another radiation structure. When the first feed source 121 is electrically connected to the first feed point 112 between the first end 111 and the first ground point 113, the first feed source 121 and the first radiation section 117 can form a first positioning antenna, and under the action of the first feed source 121, the first positioning antenna can at least support the first positioning signal. When the second feed source 122 is electrically connected to the second feed point 115 between the second end 116 and the second ground point 114, the second feed source 122 and the second radiation section 118 can form a second positioning antenna, and under the action of the second feed source 122, the second positioning antenna can at least support the second positioning signal. Therefore, the electronic device 10 of the embodiment of the present application can be provided with two positioning antennas on the first short frame 430.

[0036] It can be understood that the first positioning signal supported by the first positioning antenna and the second positioning signal supported by the second positioning antenna can be, but are not limited to, GPS signals, Beidou Navigation Satellite System (BDS) signals, Galileo signals, and GLONASS signals. Among them, the frequency bands of the first positioning signal supported by the first positioning antenna and the second positioning signal supported by the second positioning antenna can be the same, for example, the first positioning signal and the second positioning signal can both be GPS-L1 frequency band (1575.42MHz±1.023MHz) signals, or, the first positioning signal and the second positioning signal can both be GPS-L5 frequency band (1166.45MHz±1.023MHz) signals. Of course, the first positioning signal and the second positioning signal can be signals of different frequency bands, for example, one of the positioning signals can be a GPS-L1 frequency band signal, and the other positioning signal can be a GPS-L5 frequency band signal. This embodiment of the present application is not limited to this.

[0037] It is understandable that the ground plane 130 can form a common ground for the electronic device 10. The ground plane 130 can be a plane or structure with zero potential. Among them, the ground plane 130 can be formed by a conductor, a printed circuit or a metal printed layer in the electronic device 10; or, the ground plane 130 can be formed on the main board, a small board or other supporting board of the electronic device 10; or, the ground plane 130 can also be formed on the frame of the electronic device 10 (such as the first middle plate 450 and the second middle plate 460 described later). The embodiment of the present application does not limit the specific setting position of the ground plane 130. Among them, the first grounding point 113 and the second grounding point 114 can be, but not limited to, grounding connection with the ground plane 130 in the form of grounding pads, grounding springs, etc.

[0038] It is understandable that the area between the first grounding point 113 and the second grounding point 114 of the first radiator 110 can be grounded to reduce interference between the first positioning antenna and the second positioning antenna. Of course, no additional grounding points may be set in the area between the first grounding point 113 and the second grounding point 114, or the first grounding point 113 and the second grounding point 114 may overlap so that the first radiation section 117 and the second radiation section 118 share the same grounding point. This embodiment of the present application is not limited to this.

[0039] In the electronic device 10 of the embodiment of the present application, the first radiator 110 is arranged on the first short frame 430 of the middle frame 400, and the first radiating section 117 between the first end 111 and the first grounding point 113 on the first radiator 110 and the second radiating section 118 between the second end 116 and the second grounding point 114 can be arranged on the first short frame 430. When the first radiating section 117 and the second radiating section 118 both support positioning signals, the electronic device 10 of the present application may include two positioning antennas, and the radiation structure of the two positioning antennas can be set on the first short frame 430. When the user holds the electronic device 10 vertically, it is not easy to hold the two positioning antennas at the same time, so the positioning antenna performance of the electronic device 10 in the hand-held state can be guaranteed, and the electronic device 10 has good anti-hand-holding performance when supporting positioning signals.

[0040] Please combine Figure 1 and Figure 2 Please also refer to Figure 3 and Figure 4 , Figure 3 A second structural diagram of the electronic device 10 provided in an embodiment of the present application is shown in FIG. Figure 4 for Figure 3 The electronic device 10 is shown in another structural diagram. Figure 3 and Figure 4 As shown, the electronic device 10 may further include a first body 200 and a second body 300 . The first body 200 and the second body 300 may move toward each other so that the electronic device 10 has a foldable structure.

[0041] It can be understood that the first long frame 410 includes a first part 411 and a second part 412 connected to each other, and the second long frame 420 includes a third part 421 and a fourth part 422 connected to each other. The electronic device 10 can also include a hinge structure 500, which can enable the electronic device 10 to be folded along an axis extending along the second direction H2. The axis can serve as a dividing line between the first part 411 and the second part 412, and a dividing line between the third part 421 and the fourth part 422, so that the first body 200 includes a first short frame 430, a part of the first long frame 410 such as the first part 411 and a part of the second long frame 420 such as the third part 421; the second body 300 can include a second short frame 440, another part of the first long frame 410 such as the second part 412 and another part of the second long frame 420 such as the fourth part 422, and the second body 300 can be folded or unfolded relative to the first body 200 along the axis of the electronic device 10. In the unfolded state, the first part 411 and the second part 412 of the first long frame 410 may form the first long frame 410 extending along the first direction H1, the third part 421 and the fourth part 422 of the second long frame 420 may form the second long frame 420 extending along the first direction H1, the first short frame 430 and the second short frame 440 may be arranged opposite to each other and respectively form the top frame and the bottom frame of the electronic device 10, the first short frame 430 may be arranged toward the sky, and the second short frame 440 may be arranged toward the earth; in the unfolded state, the length of the first short frame 430 and the second short frame 440 (for example, the size along the second direction H2) is smaller than the length of the first long frame 410 and the second long frame 420 (for example, the size along the first direction H1). In the folded state, the first part 411 and the second part 412 of the first long frame 410 may overlap each other, the third part 421 and the fourth part 422 of the second long frame 420 may overlap each other, and the first short frame 430 and the second short frame 440 may also overlap each other.

[0042] It is understood that the middle frame 400 of the electronic device 10 may also include a middle plate, for example, a first middle plate 450 and a second middle plate 460, which may provide support for the electronic devices or functional components of the electronic device 10. The first body 200 may include a first middle plate 450, and the second body 300 may include a second middle plate 460. The first short frame 430, the first portion 411 of the first long frame 410, and the third portion 421 of the second long frame 420 may be connected to the first middle plate 450. The second short frame 440, the second portion 412 of the first long frame 410, and the fourth portion 422 of the second long frame 420 may be connected to the second middle plate 460. When the first middle plate 450 and the second middle plate 460 include a conductor structure, the ground plane 130 of the electronic device 10 may be formed on at least one structure of the first middle plate 450 and the second middle plate 460. For example, the ground plane 130 may include a first ground region and a second ground region, the first ground region may be formed on the first middle plate 450, and the second ground region may be formed on the second middle plate 460. Of course, it should be noted that the ground plane 130 of the electronic device 10 may also be formed on other structures of the electronic device 10, and the embodiment of the present application is not limited to this.

[0043] It can be understood that when the electronic device 10 is folded along the axis (also called folding up and down, or small folding), the size of the electronic device 10 along the first direction H1 becomes smaller, and the compact electronic device 10 is more popular with female users. However, for such a small folding electronic device 10, on the one hand, the antennas on the overlapping first body 200 and second body 300 will also overlap and cause mutual interference; on the other hand, the size of the folded electronic device 10 along the first direction H1 becomes smaller, and it is easier for the user to hold the electronic device 10, which makes the antenna of the folded electronic device 10 more easily affected by the user's hand, and the anti-hand-holding performance of the folded electronic device 10 is worse.

[0044] For example, please refer to Figure 5 and Figure 6 , Figure 5 for Figure 4 The electronic device 10 is a schematic structural diagram in a hand-held state. Figure 6 for Figure 4 The electronic device 10 is shown in another structural diagram of the hand-held state. Figure 5 As shown, after the electronic device 10 is folded up and down along the axis, when the user holds the folded electronic device 10 in a posture such as left hand, the first long frame 410 and the second long frame 420 of the electronic device 10 along the first direction H1 are both easier to be held by the user, and part of the first short frame 430 and the second short frame 440 of the electronic device 10 along the second direction H2 are held by the user, and the other part is not held by the user. Figure 6As shown, when the user holds the folded electronic device 10 in another posture, for example, with the right hand, the first long frame 410 and the second long frame 420 of the electronic device 10 along the first direction H1 are also easily held by the user, and a portion of the first short frame 430 and the second short frame 440 along the second direction H2 of the electronic device 10 is held by the user (the region is different from the region of the first short frame 430 and the second short frame 440). Figure 5 The first short frame 430 and the second short frame 440 are held by the left hand when the user holds the electronic device 10 in the folded state, and the other part is not held by the user. That is to say, in the folded state, the first long frame 410 and the second long frame 420 of the electronic device 10 along the first direction H1 are basically completely held by the user's hand. The electronic device 10 in the related art often sets the positioning antenna on the long frame. When the positioning antenna of the related art is applied to the new form of the electronic device 10 that folds up and down, the performance of the positioning antenna will be greatly reduced, and the anti-hand-holding performance of the positioning antenna is low.

[0045] In the electronic device 10 of the embodiment of the present application, the first radiator 110 is arranged on the first short frame 430, and the first radiating section 117 and the second radiating section 118 of the first radiator 110 are also arranged on the first short frame 430, and two positioning radiation structures can be arranged on the first short frame 430. When the electronic device 10 is in the unfolded state or the folded state, it is not easy for the user to hold the first radiating section 117 and the second radiating section 118 at the same time when holding the electronic device 10 with the left hand or the right hand, and it is not easy for the user to completely hold the two positioning antennas, which makes at least one of the two positioning antennas of the present application not held by the user, which can ensure the positioning performance of the electronic device 10 and improve the anti-hand-holding performance of the electronic device 10 in the folded state.

[0046] It should be noted that when the electronic device 10 is folded along the axis, the electronic device 10 can fold the first body 200 toward the direction where the second body 300 is located. At this time, the first short frame 430 and the second short frame 440 overlap and are both located at the bottom of the folded electronic device 10; the electronic device 10 can also fold the second body 300 toward the direction where the first body 200 is located. At this time, the first short frame 430 and the second short frame 440 overlap and are both located at the top of the folded electronic device 10. Since the positioning satellite is located at the top of the sky, in order to make the positioning performance of the electronic device 10 better, the present application can make the second body 300 fold toward the first body 200 and make the first short frame 430 face the sky. In actual use, a secondary display screen (for example Figure 5 and Figure 6When the electronic device 10 is in the folded state, the user can perform display operations through the sub-display screen on the back of the second body 300. At this time, limited by the setting position of the sub-display screen, the user tends to fold the second body 300 along the axis toward the first body 200, so that the folded first short frame 430 can still face the sky.

[0047] Among them, in order to better improve the positioning performance of the electronic device 10, the electronic device 10 can control the first feed source 121 and the second feed source 122 to work simultaneously. At this time, the first radiation section 117 and the second radiation section 118 can simultaneously support the positioning signal of the same frequency band, and the electronic device 10 can achieve positioning through two positioning antennas, and the positioning of the electronic device 10 is more accurate. Of course, the electronic device 10 also controls the feed source corresponding to the positioning signal with stronger signal strength in the first positioning signal and the second positioning signal to work, so that the electronic device 10 can select the positioning antenna with stronger performance in the two positioning antennas to work, thereby ensuring the positioning performance of the electronic device 10.

[0048] For example, please refer to Figure 7 , Figure 7 A schematic diagram of a circuit structure of an electronic device 10 of an embodiment of the present application. When the first positioning signal and the second positioning signal are positioning signals of the same type and the same frequency band, taking the first positioning signal and the second positioning signal as GPS-L1 frequency band signals as an example, the electronic device 10 may include a GPS-L1 frequency band signal radio frequency path, and the electronic device 10 may include a positioning signal radio frequency module 21 (for example, a GPS-L1 frequency band radio frequency module) and a switching switch 22, wherein the output end of the positioning signal radio frequency module 21 may be electrically connected to the input end a1 of the switching switch 22, and one output end of the switching switch 22, for example, the first output end b1, may be electrically connected to the first feeding point 112 to achieve electrical connection with the first radiation section 117, and another output end of the switching switch 22, for example, the second output end b2, may be electrically connected to the second feeding point 115 to achieve electrical connection with the second radiation section 118. When the input end a1 of the switching switch 22 is connected to the first output end b1, the first radiation section 117 between the first end 111 of the first radiator 110 and the first grounding point 113 can form a first RF link with the positioning signal RF module 21, and the first radiation section 117 can support the first positioning signal of the GPS-L1 frequency band. When the input end a1 of the switching switch 22 is connected to the second output end b2, the second radiation section 118 between the second end 116 of the first radiator 110 and the second grounding point 114 can form a second RF link with the positioning signal RF module 21, and the second radiation section 118 can support the second positioning signal of the GPS-L1 frequency band. Thus, under the switching of the switching switch 22, the electronic device 10 can select the first radiation section 117 or the second radiation section 118 to support the positioning signal.

[0049] It can be understood that the output end of the positioning signal RF module 21 and the input end a1 and the first output end b1 of the switching switch 22 can form the first feed source 121 of the electronic device 10, and the output end of the positioning signal RF module 21 and the input end a1 and the second output end b2 of the switching switch 22 can form the second feed source 122 of the electronic device 10, so that the electronic device 10 can control the operation of the first feed source 121 or the second feed source 122 through the switching switch 22.

[0050] It can be understood that when the electronic device 10 is in a folded state or an unfolded state, the first positioning signal supported by the first radiation segment 117 and the second positioning signal supported by the second radiation segment 118 may be interfered with by the user's hand or other interference factors. At this time, the electronic device 10 can obtain the signal strength of the first positioning signal and the signal strength of the second positioning signal (for example, the electronic device 10 can control the input end a1 of the switching switch 22 to be connected to the first output end b1 and the second output end b2 respectively to obtain the signal strength of the first positioning signal and the second positioning signal respectively). Then the electronic device 10 can select a positioning signal with a greater signal strength, and control the switching switch 22 to turn on the corresponding link so that the feed source corresponding to the positioning signal works. The electronic device 10 can perform the positioning function with the positioning signal with better performance, and the positioning performance of the electronic device 10 is better.

[0051] It is understandable that if Figure 7 As shown, the electronic device 10 may also include other radio frequency devices, such as filters 23 and power amplifiers 24. Among them, the filter 23 refers to a device that can effectively filter out a specific frequency or frequencies other than a specific frequency to obtain a specific frequency or eliminate a signal of a specific frequency. The power amplifier 24 refers to a device that amplifies weak signals. The first radio frequency link formed by the first radiation segment 117 and the positioning signal radio frequency module 21 may include one or more filters 23 and power amplifiers 24; the second radio frequency link formed by the second radiation segment 118 and the positioning signal radio frequency module 21 may also include one or more filters 23 and power amplifiers 24. The embodiments of the present application are not limited to this.

[0052] It is understandable that, considering that the area of ​​the first short border 430 held by the user is different when the user holds the electronic device 10 with the left hand and the user holds the electronic device 10 with the right hand, the electronic device 10 can also control the operation of the first feed source 121 and the second feed source 122 according to the user's holding posture. For example, when the electronic device 10 is in a folded state and its display surface faces the user, if the user holds the electronic device 10 vertically with the left hand, the second radiation section 118 is easily blocked, and if the user holds the electronic device 10 vertically with the right hand, the first radiation section 117 is easily blocked; then, if it is detected that the electronic device 10 is in a left-handed holding posture in the folded state, at this time, the electronic device 10 can directly control the first feed source 121 to work (for example, control the switching switch 22 to turn on the input terminal a1 and the first output terminal b1), so that the first feed source 121 excites the first radiation section 117 to support the first positioning signal; if it is detected that the electronic device 10 is in a right-handed holding posture in the folded state, at this time, the electronic device 10 can directly control the second feed source 122 to work (for example, control the switching switch 22 to turn on the input terminal a1 and the second output terminal b2), so that the second feed source 122 excites the second radiation section 118 to support the second positioning signal. Thus, the electronic device 10 can use the positioning signal with a stronger signal for positioning, and the positioning accuracy of the electronic device 10 is higher.

[0053] It is understandable that the electronic device 10 can determine the user's holding posture through a posture sensor and a proximity sensor, but is not limited to it. For example, the electronic device 10 may include a proximity sensor, which can detect the proximity state between the electronic device 10 and an object (such as a user's hand), so that the electronic device 10 can control the first feed 121 or the second feed 122 to work according to the proximity state. Exemplarily, the electronic device 10 can set multiple proximity detection areas in the first long frame 410, the second long frame 420, the first short frame 430 and the second short frame 440 or other areas, and then determine the proximity state between the electronic device 10 and the object (such as the user's hand) according to the detection results of the multiple proximity detection areas to obtain the user's holding posture; subsequently, the electronic device 10 can control the first feed 121 or the second feed 122 to work according to the proximity state or the holding posture.

[0054] It should be noted that the electronic device 10 may also control the operation of the first feed source 121 or the second feed source 122 in other ways, which is not limited in the embodiment of the present application.

[0055] Among them, please refer to Figure 8 and Fig. 9 , Figure 8 A schematic diagram of an S11 curve and an efficiency curve of an electronic device 10 provided in an embodiment of the present application, Fig. 9 This is a schematic diagram of a radiation direction of the electronic device 10 according to an embodiment of the present application. Figure 8 The middle curve S1 and curve S2 are respectively the S11 curve and the antenna efficiency curve when the second feed source 122 excites the second radiation section 118 to support the second positioning signal, such as the GPS-L1 frequency band signal. It can be seen from the curve S1 and the curve S2 that the second radiation section 118 supports the GPS-L1 frequency band signal and has better antenna performance. And, Fig. 9 The second radiation segment 118 supports the direction diagram of the GPS-L1 frequency band signal, which is Fig. 9 It can be seen that the second radiation segment 118 supports GPS-L1 frequency band signals with a higher upper hemisphere share, and the electronic device 10 can better communicate with the GPS satellite, so that the GPS performance of the electronic device 10 is better.

[0056] It is understandable that when the first positioning signal and the second positioning signal are positioning signals of different types or different frequency bands, the electronic device 10 can also use the above-mentioned RF architecture (if the first positioning signal and the second positioning signal are positioning signals of different types, at this time, the electronic device 10 can include positioning signal RF modules corresponding to the two positioning signals, and the switch 22 can select a suitable positioning signal RF module to be connected to the corresponding radiation segment) to select a positioning signal with stronger signal strength for positioning. The embodiment of the present application is not limited to this.

[0057] It can be understood that when the first positioning signal and the second positioning signal are positioning signals of different types or different frequency bands, the electronic device 10 can also control the first feed source 121 and the second feed source 122 to work simultaneously. For example, if the first positioning signal and the second positioning signal share the same positioning signal RF module 21, at this time, the switching switch 22 can control the input terminal a1 to be simultaneously connected to the first output terminal b1 and the second output terminal b2 (for example, the switching switch 22 can be a double-pole double-throw switch), so that the electronic device 10 can simultaneously control the first feed source 121 and the second feed source 122 to work, the first radiation section 117 and the second radiation section 118 can simultaneously support the first positioning signal and the second positioning signal, and the electronic device 10 can achieve dual positioning signal positioning, and the positioning of the electronic device 10 is more accurate. Exemplarily, the first positioning signal can be a GPS-L1 frequency band signal, the second positioning signal can be a GPS-L5 frequency band signal, and the electronic device 10 can achieve dual GPS positioning. For another example, if the first positioning signal and the second positioning signal are each electrically connected to a positioning signal RF module, at this time, the control switch may include two input terminals and two output terminals (for example, the control switch is a double-pole double-throw switch, or two single-pole single-throw switches), and the control switch may realize the electrical connection between a positioning signal RF module and the first radiation segment 117 through one input terminal and one output terminal, and the control switch may realize the electrical connection between another positioning signal RF module and the second radiation segment 118 through another input terminal and another output terminal, so that the first radiation segment 117 and the second radiation segment 118 can simultaneously support the first positioning signal and the second positioning signal, and the electronic device 10 can also realize dual positioning signal positioning, and the positioning of the electronic device 10 is more accurate. It should be noted that the embodiment of the present application does not limit the specific manner in which the first feed 121 and the second feed 122 work simultaneously.

[0058] It can be understood that when the first radiator 110 also supports the transmission and reception of the first Wi-Fi signal (transmission and reception includes transmission and reception) under the stimulation of the first feed source 121, as shown in FIG. Figure 7As shown, the electronic device 10 may also include a Wi-Fi signal RF module 25 and a frequency divider 26. The frequency divider 26 is also called a splitter or distributor. The frequency divider 26 can divide one signal into multiple signals and can support the inverse process of the process. At this time, the first feed source 121 may also include a Wi-Fi signal RF module 25 and a frequency divider 26. The Wi-Fi signal RF module 25 may be electrically connected to the frequency divider 26, and the frequency divider 26 may also be electrically connected to the first output terminal b1 of the switching switch 22. The frequency divider 26 may mix the positioning signal and the Wi-Fi signal transmitted through the switching switch 22 and transmit them to the first radiation section 117, so that the first radiation section 117 can simultaneously transmit the first positioning signal and the first Wi-Fi signal; the first positioning signal and the first Wi-Fi signal received by the first radiation section 117 may also be transmitted to the positioning signal RF module 21 and the Wi-Fi signal RF module 25 through the frequency divider 26, respectively, so as to realize the reception of the first positioning signal and the first Wi-Fi signal. For example, the first positioning signal is a GPS-L1 frequency band signal, and the first Wi-Fi signal is a 2.4G Wi-Fi signal. Figure 7 Under the RF architecture shown, the first radiation segment 117 can support both GPS-L1 frequency band signals and 2.4G Wi-Fi signals. It should be noted that the first Wi-Fi signal may also be a Wi-Fi signal of other frequency bands, for example, the first Wi-Fi signal may also be a 5G Wi-Fi signal, which is not limited in the present application embodiment.

[0059] The electronic device 10 of the embodiment of the present application can select the feed source corresponding to the positioning signal with stronger signal strength between the first positioning signal and the second positioning signal. The electronic device 10 can perform the positioning operation through the positioning signal with stronger signal strength, and the positioning of the electronic device 10 is more accurate.

[0060] Among them, please refer to Fig.10 , Fig.10 This is a third structural diagram of the electronic device 10 provided in the embodiment of the present application. The electronic device 10 may further include a metal decorative part 140 and a third feed source 123 .

[0061] The metal decorative part 140 can be set on the first body 200 or the second body 300. The metal decorative part 140 can be directly or indirectly electrically connected to the ground plane 130 to achieve grounding. The third feed source 123 can be electrically connected to the metal decorative part 140. The third feed source 123 and the metal decorative part 140 can form a third positioning antenna. The third feed source 123 can excite the metal decorative part 140 to support the third positioning signal.

[0062] It is understandable that the third positioning signal may be, but is not limited to, a GPS signal, a Beidou positioning signal, a Galileo positioning signal, a GLONASS positioning signal, etc. The third positioning signal may be a positioning signal of the same frequency band as the first positioning signal or the second positioning signal, or the third positioning signal may be a positioning signal of a different frequency band than the first positioning signal and the second positioning signal.

[0063] For example, when the first positioning signal and the second positioning signal are both positioning signals of the same frequency band, such as but not limited to GPS-L1 frequency band signals, the third positioning signal may be a positioning signal of a different frequency band from the first positioning signal and the second positioning signal, such as but not limited to GPS-L5 frequency band signals. At this time, the third positioning signal supported by the metal decorative part 140 can assist the first positioning signal and the second positioning signal to achieve positioning, thereby making the positioning of the electronic device 10 more accurate. In some embodiments, the electronic device 10 can obtain the signal strength of the first positioning signal and the second positioning signal, and the electronic device 10 can also control the feed source corresponding to the positioning signal with stronger signal strength in the first positioning signal and the second positioning signal to work; at this time, the electronic device 10 can control the third feed source 123 to be in a working state, so that the electronic device 10 controls the first feed source 121 and the third feed source 123 to work simultaneously, or controls the second feed source 122 and the third feed source 123 to work simultaneously. In other embodiments, the electronic device also includes a proximity sensor, which can detect the proximity state between the electronic device 10 and an object (such as a user's hand), and the electronic device 10 can also control the first feed source 121 or the second feed source 122 to work according to the proximity state; at this time, the electronic device 10 can also control the third feed source 123 to be in a working state, so that the electronic device 10 controls the first feed source 121 and the third feed source 123 to work at the same time, or controls the second feed source 122 and the third feed source 123 to work at the same time.

[0064] For another example, when one of the first positioning signal and the second positioning signal is a GPS-L1 frequency band signal and the other is a GPS-L5 frequency band signal, the third positioning signal supported by the metal decorative part 140 may be a GPS-L1 frequency band signal or a GPS-L5 frequency band signal. In some embodiments, the electronic device 10 may control the third feed 123 to select and support one signal between the GPS-L1 frequency band signal and the GPS-L5 frequency band signal according to the working status of the first feed 121 and the second feed 122, so that the frequency band of the positioning signal supported by the metal decorative part 140 is different from the frequency band of the positioning signal supported by the feed working in the first feed 121 and the second feed 122, so that the electronic device 10 can achieve dual GPS positioning. It should be noted that the first positioning signal to the third positioning signal may also be other positioning signals, which are not limited here.

[0065] It should be noted that the first positioning signal, the second positioning signal, and the third signal can also be positioning signals of the same frequency band, and the electronic device can also control the first feed source 121, the second feed source 122, and the third feed source 123 to work simultaneously. The embodiment of the present application does not limit the specific working mode of the three feed sources.

[0066] It is understandable that the metal decorative part 140 is often used to modify the functional module 600 of the electronic device 10 (for example, but not limited to, the camera module and sensor module of the electronic device 10) so that the electronic device 10 has a certain aesthetic feeling. Among them, the electronic device 10 may include a rear shell 700, which may be connected to the middle frame 400 and form a certain accommodation space. A through hole may be provided on the rear shell 700, and the functional module 600 of the electronic device 10 may be located in the accommodation space and collect signals outside the electronic device 10 through the through hole. A part of the metal decorative part 140 may be located inside the rear shell 700, another part of the metal decorative part 140 may be located on the outer surface of the rear shell 700, and the metal decorative part 140 may be arranged around the functional module. Of course, all the metal decorative parts 140 may also be located on the outer surface of the rear shell 700, and the embodiment of the present application is not limited to this.

[0067] It is understandable that when the electronic device 10 is a foldable structure, the back shell 700 of the electronic device 10 may also include two parts, for example, the back shell 700 includes a fifth part 710 and a sixth part 720, the first body 200 may include the fifth part 710 of the back shell 700, the second body 300 may include the sixth part 720 of the back shell 700, and the metal decorative part 140 may be arranged on the back shell 700 of the first body 200. When the electronic device 10 is folded along the axis so that the second short frame 440 of the second body 300 overlaps with the first short frame 430 and the first short frame 430 and the second short frame 440 are both arranged toward the sky and away from the ground, at this time, the fifth part 710 of the back shell 700 of the first body 200 is still opposite to the display surface of the electronic device 10. And, by Figure 4 and Figure 5 As shown, it is generally difficult for a user to hold the metal decorative part 140, so that the user's hand holding is not likely to affect the antenna performance of the metal decorative part 140. The electronic device 10 reuses the metal decorative part 140 as a radiator with better anti-hand holding performance. It should be noted that the metal decorative part 140 can also be set in the sixth part 720 of the second body 300, and the embodiment of the present application does not limit the specific setting position of the metal decorative part 140.

[0068] It is understandable that when the third feed source 123 is electrically connected to the metal decorative part 140, the third feed source 123 can excite the metal decorative part 140 to support the third positioning signal, and the metal decorative part 140 can be reused as a radiation structure. In order to better improve the radiation performance of the metal decorative part 140 reused as a radiation structure, one or more (two or more) grounding points can be set in a suitable area of ​​the metal decorative part 140, and the metal decorative part 140 can be electrically connected to the ground plane 130 at more grounding points to achieve grounding. When the metal decorative part 140 supports the third positioning signal, less clutter is generated on the metal decorative part 140, and the antenna performance of the metal decorative part 140 supporting the third positioning signal is better.

[0069] It is understandable that in order to further reduce the clutter on the metal decorative member 140, such as Fig.10 As shown, the electronic device 10 may also be provided with one or more matching structures 150, and a matching structure 150 may be electrically connected between the ground point of the metal decorative part 140 and the ground plane 130. Through the adjustment of the matching structure 150 (also called matching circuit, matching network, which may include components such as capacitors and inductors), the clutter on the metal decorative part 140 is smaller. Among them, when the structure of the metal decorative part 140 is relatively regular and the electrical length meets the design requirements, the matching structure 150 may be a zero-ohm component to further improve the antenna performance of the metal decorative part 140.

[0070] In the electronic device 10 of the embodiment of the present application, the first radiating section 117 and the first feed source 121 between the first end 111 and the first grounding point 113 on the first radiator 110 can form a first positioning antenna and support a first positioning signal, the second radiating section 118 and the second feed source 122 between the second end 116 and the second grounding point 114 can form a second positioning antenna and support a second positioning signal in the same frequency band as the first positioning signal, and the metal decorative part 140 and the third feed source 123 can form a third positioning antenna and support a third positioning signal in a different frequency band from the first positioning signal; the electronic device 10 can reuse the metal decorative part 140 as a radiation structure for the third positioning signal, and the electronic device 10 can achieve a miniaturized design; at the same time, the metal decorative part 140 and the first radiating section 117 and the second radiating section 118 arranged on the first short frame 430 are Due to the different setting positions, when the electronic device 10 is in a folded form in which the first short frame 430 is folded along the axis of the extension direction of the first short frame 430 (for example, the second direction H2) so that the first short frame 430 of the first body 200 overlaps with the second short frame 440 of the second body 300, it is not easy for the user to hold the metal decorative part 140, the first radiation section 117 and the second radiation section 118 at the same time when holding the electronic device 10. This enables the electronic device 10 of the present application to still support positioning signals of at least two different positioning frequency bands when folded and held in the hand, and the third positioning signal supported by the metal decorative part 140 can assist the first positioning signal or the second positioning signal, so that the electronic device 10 of the present application can not only achieve a miniaturized design, but also ensure that the electronic device 10 has better anti-hand-holding performance in the folded state, and the positioning performance of the electronic device is better.

[0071] Based on the structure of the electronic device 10, please refer to Fig.11 , Fig.11 This is a fourth structural diagram of the electronic device 10 provided in the embodiment of the present application. The electronic device 10 further includes a second radiator 160 and a fourth feed source 124 .

[0072] A portion of the second radiator 160 may be disposed on the first short frame 430, another portion of the second radiator 160 may be disposed on the second long frame 420, such as the third portion 421, one end of the second radiator 160 may be spaced apart from the second end 116 of the first radiator 110, and the other end of the second radiator 160 may extend in a direction away from the first radiator 110 and be electrically connected to the ground plane 130 to achieve grounding. The fourth feed 124 may be directly or indirectly electrically connected to the second radiator 160, and the fourth feed 124 may excite the second radiator 160 to support the first wireless signal.

[0073] It can be understood that the first wireless signal can be, but is not limited to, a Wi-Fi signal, a positioning signal, a 3G signal, a 4G signal, a 5G signal, an NFC signal, a Bluetooth signal, a UWB signal, etc. Among them, the first wireless signal can be a single type of wireless signal, and the first wireless signal can also be multiple types of wireless signals. For example, the fourth feed source 124 can excite the second radiator 160 to support at least one of the wireless signals of the medium and high frequency signal (1710MHz-2690MHz) and the N78 frequency band (3300MHz-3800MHz). When the second radiator 160 supports both the medium and high frequency signal and the wireless signal of the N78 frequency band, the excitation signal provided by the fourth feed source 124 can excite the second radiator 160 to form two resonant current paths, wherein one resonant current path can excite the second radiator 160 to support the transmission and reception of the medium and high frequency signal, wherein the other resonant current path can excite the second radiator 160 to support the transmission and reception of the wireless signal of the N78 frequency band, so that the second radiator 160 can simultaneously realize the transmission and reception of the medium and high frequency signal and the N78 frequency band signal. The embodiment of the present application does not specifically limit the first wireless signal.

[0074] It can be understood that the fourth feed source 124 can be electrically connected between the two ends of the second radiator 160, and the fourth feed source 124 can also be electrically connected to one end of the second radiator 160 close to the first radiator 110, and the embodiment of the present application does not limit this. Among them, since the free ends of the second radiator 160 and the second radiating section 118 of the first radiator 110 are opposite and a gap is formed between the free ends of the two, the grounded ends of the second radiator 160 and the second radiating section 118 are far away from each other, so that the second radiator 160 and the second radiating section 118 can form a mouth-to-mouth antenna structure, and the second radiator 160 and the second radiating section 118 are easy to electromagnetically couple. When the fourth feed source 124 excites the second radiator 160 to support the first wireless signal, the fourth feed source 124 can also excite the second radiator 160 and the second radiating section 118 to jointly support the first wireless signal. The embodiment of the present application does not limit the specific excitation form of the first wireless signal.

[0075] It is understandable that the first wireless signal may be different from the second positioning signal. Exemplarily, the first wireless signal and the second positioning signal may be wireless signals with a large frequency difference. For example, the first wireless signal may be a medium-high frequency wireless signal, and the second positioning signal may be a GPS-L1 frequency band signal. In this case, the interference between the two wireless signals is small. Of course, the first wireless signal and the second positioning signal may also be other wireless signals, which is not limited in the embodiments of the present application.

[0076] In order to further reduce the interference of the first wireless signal to the second positioning signal, please refer to Fig.11 , the electronic device 10 may further include a matching circuit 170 .

[0077] The matching circuit 170 may be directly or indirectly electrically connected between the second feed source 122 and the second feed point 115. The matching circuit 170 may allow the first resonant current formed when the second feed source 122 excites and generates the second positioning signal to pass through, and is used to cut off the second resonant current formed when the fourth feed source 124 excites and generates the first wireless signal to pass through.

[0078] It can be understood that when the second feed source 122 excites the second radiation section 118 to support the second positioning signal, a first resonant current can be generated on the second radiation section 118. The first resonant current can pass through the second feed source 122 and flow to the second radiator 160 to form a resonant mode and enable the second radiation section 118 to support the second positioning signal. The first resonant current can pass through the matching circuit 170 and flow to the second radiation section 118. When the fourth feed source 124 excites the second radiator 160 to support the first wireless signal, the second resonant current generated on the second radiator 160 can be electromagnetically coupled to the second radiating section 118 through the gap between the second radiating section 118 and the second radiator 160 and flow on the second radiating section 118. Since the matching circuit 170 can cut off the second resonant current, the second resonant current is not easy to flow into the second feed source 122 through the matching circuit 170, so that the second resonant current is not easy to interfere with the second feed source 122. When the second radiator 160 supports the first wireless signal, the interference to the second radiating section 118 supporting the second positioning signal is relatively small. The antenna performance of the electronic device 10 that supports the first wireless signal and the second positioning signal at the same time is better.

[0079] It is understandable that the matching circuit 170 may include, but is not limited to, electronic components such as capacitors, inductors, and switches. Fig.11 Please also refer to Fig.12 , Fig.12 for Fig.11 An electrical connection diagram of a matching circuit 170 is shown. The matching circuit 170 may include a first inductor element 171 , a first capacitor element 172 , a second inductor element 173 and a third inductor element 174 .

[0080] One end of the first inductor element 171 may be directly or indirectly electrically connected between the second feed source 122 and the second feed point 115, one end of the first capacitor element 172 may be electrically connected to one end of the first inductor element 171, and the other end of the first capacitor element 172 is electrically connected to the ground plane 130 to achieve grounding. One end of the second inductor element 173 is directly or indirectly electrically connected between one end of the first inductor element 171 and the second feed source 122, and the other end of the second inductor element 173 is electrically connected to the ground plane 130 to achieve grounding. One end of the third inductor element 174 is directly or indirectly electrically connected to one end of the second inductor element 173, and the other end of the third inductor element 174 is electrically connected to the second feed source 122.

[0081] It can be understood that the first inductance element 171 and the first capacitance element 172 can be connected in series with each other, and the whole after the two are connected in series can be connected in parallel with the second inductance element 173 to form a new whole, and at this time, the new whole can be connected in series with the third inductance element 174 between the second feed source 122 and the second feeding point 115. Among them, the whole formed by the first inductance element 171, the first capacitance element 172 and the second inductance element 173 can filter out the second resonant current formed when the fourth feed source 124 excites to generate the first wireless signal, so that the second resonant current can be returned to the ground through the first inductance element 171, the first capacitance element 172 and the second inductance element 173. At this time, the second resonant current is not easy to flow into the second feed source 122. In addition, the third inductance element 174 can further block the second resonant current from flowing into the second feed source 122, thereby further cutting off the second resonant current.

[0082] It can be understood that the inductance value of the first inductor element 171 can be but not limited to 2.7nh (nanohenry), the capacitance value of the first capacitor element 172 can be but not limited to 2.2pf (picofarad), the inductance value of the second inductor element 173 can be but not limited to 8.2nh, and the inductance value of the third inductor element 174 can be but not limited to 10nh. Of course, the parameter values ​​of the above-mentioned inductor elements and capacitor elements can also be other values, which are not limited in the embodiment of the present application.

[0083] The electronic device 10 of the embodiment of the present application prevents the second resonant current generated by the excitation of the fourth feed source 124 from flowing into the second feed source 122 through the matching circuit 170, so that the mutual interference between the second feed source 122 and the fourth feed source 124 is smaller, and the antenna performance of the electronic device 10 is better when supporting the second positioning signal and the first wireless signal at the same time.

[0084] Among them, please refer to Fig.13 , Fig.13 The fifth structural diagram of the electronic device 10 provided in the embodiment of the present application is as follows. The electronic device 10 may further include a third radiator 180 and a fifth feed source 125 .

[0085] A portion of the third radiator 180 may be disposed on the first short frame 430, another portion of the third radiator 180 may be disposed on the first long frame 410, such as the first portion 411, and the third radiator 180 may be disposed at the connecting corner of the first short frame 430 and the first long frame 410. Among them, one end of the third radiator 180 may be spaced apart from the first end 111 of the first radiator 110, and the other end of the third radiator 180 may extend in a direction away from the first radiator 110 and be electrically connected to the ground plane 130 to achieve grounding. The fifth feed 125 may be directly or indirectly electrically connected to the third radiator 180, and the fifth feed 125 is used to excite the third radiator 180 to support the second wireless signal.

[0086] It is understandable that the second wireless signal may be, but is not limited to, a Wi-Fi signal, a positioning signal, a 3G signal, a 4G signal, a 5G signal, an NFC signal, a Bluetooth signal, a UWB signal, and the like. The second wireless signal may be a single type of wireless signal, or may be multiple types of wireless signals.
