[0072] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0073] The terms used in the present disclosure are for the purpose of describing particular embodiments only and are not intended to limit the present disclosure. The singular forms "a", "said", and "the" used in the present disclosure and the appended claims are also intended to include the plural forms unless the context clearly dictates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0074] It should be understood that although the terms first, second, third, etc. may be used in the present disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "when" or "while" or "in response to a determination".

[0075] For satellite communication, the index requirements for the satellite antenna of an electronic device are relatively high. Generally, it is required that the satellite antenna be left-handed circular polarization or right-handed circular polarization. Therefore, general electronic devices are usually equipped with an external four-arm helix antenna, so that the antenna pattern points in the direction pointed by the antenna, that is, points in the zenith direction, and at the same time, the circular polarization gain is relatively high, meeting the needs of satellite calls.

[0076] However, this satellite antenna is external to the electronic device. Even though it can be stored when not in use, due to the design of the storage structure, the size requirements for the electronic device are increased, resulting in a more complex structure design of the electronic device, and also increasing the thickness and weight of the electronic device. For portable electronic devices, this goes against the original intention of users.

[0077] Based on this, the present disclosure provides an antenna accessory that can be connected to the electronic device when the electronic device needs to be used and disassembled when not in use, thereby avoiding the design of a storage structure, conforming to the development trend of the thin and light of the electronic device. At the same time, through this antenna accessory, the circular polarization gain of the electronic device can also be improved, which is beneficial to realizing the call requirements between the electronic device and the satellite.

[0078] Specifically, Figure 1It is a schematic structural diagram of an antenna accessory shown according to an exemplary illustration. As Figure 1 shown, the antenna accessory includes a bracket 1, a non-metallic substrate 2, a first metal director unit 3, a second metal director unit 4, and a third metal director unit 5. Among them, the non-metallic substrate 2 is connected to the bracket 1, and the first metal director unit 3, the second metal director unit 4, and the third metal director unit 5 are respectively disposed on the non-metallic substrate 2. The first metal director unit 3, the second metal director unit 4, and the third metal director unit 5 can be respectively used to generate resonance by coupling with the device body, and the resonance frequency points of the first metal director unit 3, the second metal director unit 4, and the third metal director unit 5 are greater than the operating frequency point of the target communication satellite. Among them, the first metal director unit 3, the second metal director unit 4, and the third metal director unit 5 can be respectively attached to the surface of the non-metallic substrate 2, or the first metal director unit 3, the second metal director unit 4, and the third metal director unit 5 can also be fully or semi-encapsulated in the non-metallic substrate 2, and can be specifically designed according to needs, and the present disclosure does not limit this.

[0079] For example, as Figure 2 shown, the present disclosure also provides an electronic device, which includes a device body and an antenna accessory. The device body includes a housing 101, a middle frame 102, and a satellite antenna 103. The metal director unit of the antenna accessory takes power by coupling with the satellite antenna. In some embodiments, the satellite antenna 103 can be a laser-formed antenna or an FPC antenna. In other embodiments, a partial frame segment of the middle frame 102 forms the satellite antenna 103 of the electronic device. When the electronic device communicates with the target communication satellite, the metal director unit closest to the satellite antenna can couple with the satellite antenna to generate resonance, and resonance can be generated between adjacent metal director units. For example, as Figure 2As shown in the figure, the first metal director unit 3 is closest to the satellite antenna 103. Therefore, the first metal director unit 3 can be coupled with the satellite antenna 103 to generate resonance. The second metal director unit 4 is arranged adjacent to the first metal director unit 3. Therefore, the second metal director unit 4 can generate resonance by coupling with the first metal director unit 3. Similarly, the third metal director unit 5 can generate resonance by coupling with the second metal director unit 4, thereby realizing the respective couplings of the first metal director unit 3, the second metal director unit 4, and the third metal director unit 5 to generate resonance. Among them, the minimum distance between the first metal director unit 3 and the satellite antenna 103 in free space can be 0.05 - 0.25 times the wavelength corresponding to the operating frequency point of the target communication satellite, H3 = (0.05 - 0.25)λ. In other words, it can be understood that when multiple metal director units are arranged on the non-metal substrate 2, when the metal director units are coupled, the minimum distance between the multiple metal director units and the satellite antenna in free space can be 0.05 - 0.25 times the wavelength corresponding to the operating frequency point of the target communication satellite. Among them, λ is the wavelength corresponding to the operating frequency point of the target communication satellite. Taking the target communication satellite as a Tiantong satellite as an example, the operating frequency point of this Tiantong satellite is 2.2 GHz. Then, the wavelength corresponding to the operating frequency point in free space is about 136 mm. Through conversion, the minimum distance between the multiple metal director units and the satellite antenna in free space is in the range of 4 mm - 40 mm. Optionally, in some dielectric environments, the minimum distance between the multiple metal director units and the satellite antenna can be adaptively changed based on different dielectric parameters or environments.

[0080] As Figure 3 shown, with the electronic device placed vertically and located in the XYZ coordinate system shown in the figure, the top of the electronic device is in the +Z direction, the bottom is in the -Z direction, the back is facing the +X direction, and the non-button side is in the +Y direction. Based on this placement method, the pattern simulation is carried out for whether the antenna accessory is configured for the electronic device. As Figure 4 shown is the left-handed pattern of the single device body in free space, Figure 5 and Figure 4 is the left-handed pattern of the electronic device in free space. As Figure 5 and Figure 4 shown, when it is a single device body, at the position indicated by the small triangular mark to the left of the right-side indicator bar in Figure 5 , the peak value of the circular polarization gain of the electronic device in the zenith direction is +0.2 dB. When the electronic device is configured with the antenna accessory, at the position indicated by the small triangular mark to the left of the right-side indicator bar in

[0081] , the peak value of the circular polarization gain of the electronic device in the zenith direction is +4.7 dB, an increase of 4.5 dB.It can be seen that, through the antenna accessory in the present disclosure, on the one hand, when the device body communicates with a satellite, the antenna pattern of the satellite antenna 103 faces the zenith direction of the antenna, enabling the user to align with the satellite by using a conventional holding method, with a low learning cost. Moreover, after configuring this antenna accessory, the circular polarization gain of the satellite antenna 103 is improved, making communication possible in some extreme weather conditions or when blocked by buildings due to the increased signal strength. At the same time, it is also conducive to implementing communication methods such as sending pictures or voice messages.

[0082] In fact, there is an angular deviation between the maximum radiation direction of the antenna pattern when the satellite antenna 103 of the device body is used independently and the maximum radiation direction when the device body is used in combination with the antenna accessory. Based on different maximum radiation directions, it is usually necessary to guide different object angles to align with the satellite in order to obtain good communication strength. Otherwise, the communication effect after adding the antenna accessory may be worse than that of the single device body communication. Therefore, for the two situations where the device body may communicate with the target communication satellite alone and the device body communicates with the target communication satellite after being equipped with the antenna accessory, it is necessary to guide the satellite alignment according to their respective satellite alignment angles to ensure the communication effect.

[0083] Therefore, still taking Figure 1 As shown, the antenna accessory further includes an identification unit 6. The identification unit 6 can be disposed on the non-metallic substrate 2. The identification unit 6 can be used to enable the device body to identify the antenna accessory, so that the device body can determine whether it is the single device body communicating with the satellite or the device body and the antenna accessory are used in combination to communicate with the target communication satellite according to the electrical connection situation. The electrical connection between the identification unit 6 and the device body can be a wireless connection. For example, the identification unit 6 can be an NFC antenna, which is identified by the NFC identification unit provided at the device body end; or, the identification unit 6 can be a Hall magnet, which can be identified by the Hall sensor provided at the device body end. Optionally, the electrical connection between the identification unit 6 and the device body can also be a wired connection. Of course, this wired connection is not limited to being connected through a data cable. Of course, it can also include a direct hard connection between the identification unit 6 and the device body, such as being plugged in through a connection terminal, or being connected through pin feet, or being connected through a metal shrapnel.

[0084] For example, referring to Figure 2 and Figure 6 , since the antenna accessory is in Figure 6 the storage state and Figure 2When in the extended state, the relative position between the recognition unit 6 and the device body changes. Taking the wireless connection between the recognition unit 6 and the device body as an example. When the relative position between the device body and the recognition unit 6 changes, the signal connection strength between the device body and the recognition unit changes. In some instances, it can be determined that an action of configuring an antenna accessory for the device body has occurred, so that the user can be guided to align with the satellite at the optimal alignment angle of the electronic device when the antenna accessory is configured; or in other instances, it can also be determined that a position change has occurred where the antenna accessory has moved from one position of the device body to another position, and depending on whether the signal connection strength changes from strong to weak or from weak to strong, the user can be guided to align with the satellite at the first alignment angle or the second alignment angle.

[0085] In the foregoing embodiment, taking the antenna accessory including three metal director units, namely the first metal director unit 3, the second metal director unit 4, and the third metal director unit 5, as an example for illustration. In other embodiments, the antenna accessory may also include a single metal director unit, or multiple metal director units with other quantities, and the multiple metal director units are arranged at intervals along a preset direction. Among them, the more the number of metal director units, the higher the peak value of the circular polarization gain is improved. However, since the increase in the number of metal director units will cause the beam width to become narrower, affecting the user experience, therefore, considering comprehensively, the number of the metal director units can be greater than or equal to 1 and less than or equal to 4.

[0086] When the antenna accessory includes multiple metal director units, during coupled power extraction, the multiple metal director units are arranged side by side and at intervals. In other words, when the satellite antenna 103 communicates with the target communication satellite, the multiple metal director units are arranged at intervals along a preset direction, so as to increase the amount of the circular gain peak value improved by the antenna accessory through the multiple metal director units. Among them, the width direction of each metal director unit can be perpendicular to the preset direction, that is, as Figure 1 and Figure 2 shown, the preset direction is the up-down direction. At this time, the width directions of the first metal director unit 3, the second metal director unit 4, and the third metal director unit 5 are perpendicular to the paper surface direction; optionally, the width direction of the metal director unit can also be parallel to the preset direction, as Figure 1 and Figure 2For example, the width directions of the first metal director unit 3, the second metal director unit 4, and the third metal director unit 5 are arranged in the up-and-down direction. The width of the metal director unit of this antenna accessory is in the range of 0.2 mm - 10 mm. For example, when the width direction of the metal director unit is parallel to the preset direction, in order to reduce the overall size of the antenna accessory, the width of the metal director unit can be set relatively narrow. And when the width direction of the metal director unit is perpendicular to the preset direction, in order to reduce the overall size of the antenna accessory, the width of the metal director unit can be set relatively wide.

[0087] Still taking the antenna accessory including the first metal director unit 3, the second metal director unit 4, and the third metal director unit 5 as an example, in free space, the lengths of the first metal director unit 3, the second metal director unit 4, and the third metal director unit 5 are all 0.35 - 0.5 times the wavelength corresponding to the operating frequency point of the target communication satellite. That is, the length L1 of the first metal director unit 3 = (0.35 - 0.5)λ, the length L2 of the second metal director unit 4 = (0.35 - 0.5)λ, the length L3 of the third metal director unit 5 = (0.35 - 0.5)λ. The lengths of the first metal director unit 3, the second metal director unit 4, and the third metal director unit 5 can be equal or unequal, as long as they are within the aforementioned range. In other words, the length of each metal director unit included in this antenna accessory is 0.35 - 0.5 times the wavelength corresponding to the operating frequency point of the target communication satellite. The lengths between multiple metal director units can be equal or unequal, and the present disclosure does not limit this. Wherein, λ is the wavelength corresponding to the operating frequency point of the target communication satellite. Among them, the metal director unit can be Figure 1 the metal director unit with the shape structure in the illustrated embodiment. In other embodiments, the metal director unit can also be in a bent shape or an arc shape. At this time, the length of the metal director unit is the sum of the lengths in the extending direction of the metal director unit.

[0088] For example, taking the Tian Tong-1 as the target communication satellite, the transmitting frequency band is (1980 MHz - 2010 MHz), and the receiving frequency band is (2170 MHz - 2200 MHz). Therefore, the resonant frequency points of Tian Tong-1 are located between 1980 MHz and 2200 MHz. Thus, the lengths of the metal director elements are 0.35 - 0.5 times the corresponding wavelengths of any resonant frequency points within this range. Taking the resonant frequency point of 2200 MHz as an example, the corresponding operating wavelength is 136 mm. Therefore, in free space, L1, L2, and L3 are respectively within the length range of 40 mm - 68 mm. When the dielectric constant of the dielectric environment where the metal director elements are located is different or the setting method is different, the lengths of the metal director elements can be adaptively adjusted according to the conversion relationship and a limited number of experiments. For example, when the first metal director element 3, the second metal director element 4, and the third metal director element 5 are in a dielectric environment with a dielectric constant of 3.5, and the non-metal substrate 2 covers the metal director elements on one side, then L1, L2, and L3 are respectively within the range of 36 mm - 61 mm, and preferably, L1, L2, and L3 can be 45 mm respectively; for another example, when the first metal director element 3, the second metal director element 4, and the third metal director element 5 are in a dielectric environment with a dielectric constant of 3.5, and the non-metal substrate 2 covers the metal director elements on both sides, then L1, L2, and L3 are respectively within the range of 36 mm - 61 mm, and preferably, L1, L2, and L3 can be 40 mm respectively.

[0089] In some embodiments, the maximum distance between two adjacent metal director elements in free space is 0.05 - 0.25 times the wavelength corresponding to the operating frequency point of the target communication satellite. For example, the interval H1 between the first metal director element 3 and the second metal director element 4 is (0.05 - 0.25)λ, and the interval H2 between the second metal director element 4 and the third metal director element 5 is (0.05 - 0.25)λ. Among them, H1 and H2 can be equal or not equal, and can be specifically designed as required. Here, λ is the wavelength corresponding to the operating frequency point of the target communication satellite. Taking the resonant frequency point of 2200 MHz as an example, the corresponding operating wavelength is 136 mm. Therefore, in free space, L1, L2, and L3 are respectively within the length range of 4 mm - 40 mm. For example, when the first metal director element 3, the second metal director element 4, and the third metal director element 5 are in a dielectric environment with a dielectric constant of 3.5, and the non-metal substrate 2 covers the metal director elements on one side, then H1 and H2 are respectively within the range of 1 mm - 36 mm, and preferably, H1 and H2 can be 20 mm respectively; for another example, when the first metal director element 3, the second metal director element 4, and the third metal director element 5 are in a dielectric environment with a dielectric constant of 3.5, and the non-metal substrate 2 covers the metal director elements on both sides, then H1 and H2 are respectively within the range of 0.5 mm - 35 mm, and preferably, H1 and H2 can be 18 mm respectively.

[0090] In some instances, the bracket 1 can be detachably connected to the housing 101 of the device body, and the non-metallic base 2 can be movably connected to the bracket 1, so that the non-metallic base 2 can be switched between an initial position and a target position relative to the bracket 1. Since the first metal director unit 3, the second metal director unit 4, and the third metal director unit 5 are all disposed on the non-metallic base 2, when the non-metallic base 2 moves relative to the bracket 1, the first metal director unit 3, the second metal director unit 4, and the third metal director unit 5 will also switch positions accordingly. When the non-metallic base 2 is in the target position, the first metal director unit 3, the second metal director unit 4, and the third metal director unit 5 are used to generate resonance by coupling with the device body.

[0091] Based on this, when the antenna accessory is connected to the electronic device through the bracket 1, the positional relationship can be switched relative to the electronic device by the movement of the non-metallic base 2 relative to the bracket 1, which is beneficial to the accommodation of the non-metallic base 2 and the metal director units disposed on the non-metallic base 2.

[0092] For example, when the non-metallic base 2 is in Figure 2 the target position, the first metal director unit 3, the second metal director unit 4, and the third metal director unit 5 are all located outside the device body, that is, all the metal director units disposed on the non-metallic base 2 are located outside the housing 101; while when the non-metallic base 2 is in Figure 6 the initial position shown, the non-metallic base 2 and the housing 101 can be overlapped, so as to avoid the antenna accessory protruding, reduce the occupied area of the electronic device, and be beneficial to the accommodation of the electronic device configured with the antenna accessory. Among them, as shown in Figure 6 and Figure 7 shown, the bracket 1 and the non-metallic base 2 can be rotatably connected. For example, the rotating shaft can be perpendicular to the paper surface, and the non-metallic base 2 rotates 180° along the paper surface, and can be switched from the initial position to the target position; or the rotating shaft can also be parallel to the paper surface, and the non-metallic base 2 can be flipped 180° to switch from the initial position to the target position; alternatively, the bracket 1 and the non-metallic base 2 can also be slidably connected, and the non-metallic base 2 slides relative to the bracket 1 to switch from the initial position to the target position.

[0093] Furthermore, the bracket 1 can be a telescopic bracket. When the metal director unit is a strip-shaped metal director unit, the telescopic direction of the bracket 1 is perpendicular to the length direction of the metal director unit, that is, as shown in Figure 1 , the telescopic direction of the bracket 1 is the up and down direction in the figure. Based on this, as shown in Figure 7 , when the non-metallic base 2 moves from Figure 6When switching from the initial position shown to the target position relative to the bracket 1, but there is a metal director unit located below the satellite antenna 103, which is not conducive to improving the circular polarization gain and efficiency of the satellite antenna 103, the bracket 1 can be switched to the extended state, so as to eject the metal director unit out of the housing 101, that is, it can be switched from the state shown in Figure 7 to the state shown in Figure 2 ; after the satellite communication is completed, the bracket 1 can also be switched to the retracted state to avoid the bracket 1 protruding outside the housing 101. Wherein, when the metal director unit is of other shapes, the telescopic direction of the bracket 1 can be the direction in which multiple metal director units are arranged at intervals.

[0094] In some embodiments, such as Figure 1 、 Figure 2 、 Figure 6 and Figure 7 shown, the non-metallic substrate 2 is arranged in a quadrilateral shape, such as a rectangular structure, to adapt to the shape of the support outer ring of the housing 101 of the device body, so as to achieve conformal between the two, and the visual abruptness effect caused by the antenna accessory configuration can be reduced. For example, the housing 101 may include a body, an opening, and a support outer ring 104 arranged around the opening. The device body further includes a camera protection film 105, and the camera protection film 105 is connected inside the support outer ring 104. When the non-metallic substrate 2 is in the initial position, as shown in Figure 6 shown, the non-metallic substrate 2 is stacked outside the camera protection film 105, and the outer peripheral shape of the non-metallic substrate 2 matches the inner peripheral shape of the support outer ring 104.

[0095] In the above embodiments, the non-metallic substrate 2 is set in a square structure as an example for illustration. In other embodiments, as shown in Figures 8 - 11 shown, the non-metallic substrate 2 can also be set in a circular structure. Similarly, as shown in Figure 9 shown, when the non-metallic substrate 2 is in the initial position, the outer peripheral shape of the non-metallic substrate 2 can match the inner peripheral shape of the support outer ring 104, reducing the abrupt visual effect caused by the configuration of the antenna accessories. In the foregoing embodiments, the metal director unit is taken as a strip structure as an example for illustration. In other embodiments, as shown in Figure 8 shown, the metal director unit can also be designed in an arc shape. Therefore, in the technical solution of the present disclosure, the shape of the metal director unit is not limited. When the metal director unit is arranged in an arc shape, the length of the metal director unit in the foregoing embodiments can be defined as the arc length of the arc-shaped metal director unit, and the distance between adjacent two metal director units can be positioned as the maximum distance between adjacent two metal director units.

[0096] Similarly, in Figures 8 - 11In the illustrated embodiment, the bracket 1 may also be movably connected to the non-metallic base 2. By the movement of the non-metallic base 2 relative to the bracket 1, the switching between the Figure 9 illustrated initial position and Figure 10 the illustrated target position can be achieved. For the relevant solutions at the initial position and the target position, reference can be made to the foregoing embodiments and will not be elaborated herein. Similarly, the bracket 1 may be a telescopic bracket. By the telescoping of the telescopic bracket, it can be switched between the Figure 10 illustrated state and Figure 11 the illustrated state, that is, all the metal director units located on the non-metallic base 2 can be ejected out of the housing. For the relevant solutions, reference can be made to the foregoing embodiments and will not be elaborated herein.

[0097] In the foregoing embodiment, taking the example of assembling the antenna accessory by detachably connecting the bracket 1 to the device body is described. In other embodiments, optionally, as Figure 12 illustrated, the antenna accessory further includes a shell sleeve 7, whereby an electronic device protective case configured with the antenna accessory can be obtained. The shell sleeve 7 is connected to the bracket 1. The shell sleeve 7 can be used to wrap the supporting device body. The device body is detachably wrapped in the shell sleeve 7 of the electronic device protective case. The device body can be fully wrapped or semi-wrapped, and the present disclosure does not limit this; when wrapping the device body with the shell sleeve 7, in order to strengthen the protection of the device body, the user usually configures the electronic device protective case for the device body for a long time. Therefore, in order to reduce the occupied area of the antenna accessory in the non-use state. As Figure 13 and Figure 14 illustrated, the bracket 1 may be a telescopic bracket, and the non-metallic base 2 can be deployed or retracted along with the telescopic bracket. That is, by the telescoping of the bracket 1, the non-metallic base 2 can be switched between the Figure 13 illustrated deployed state and Figure 14 the illustrated retracted state. When the non-metallic base 2 is in the deployed state, when the antenna accessory includes a plurality of metal director units, the plurality of metal director units can be arranged at intervals along a preset direction, whereby the plurality of metal director units are beneficial to increasing the amount of circular gain peak improved by the antenna accessory.

[0098] When forming the satellite antenna 103 through the middle frame 102 and both ends of the satellite antenna 103 are used to form the antenna slot 106, in order to avoid that the metal director units made of metal material are too long to cover the antenna slot 106, resulting in the deterioration of the radiation efficiency of some frequency bands of the top antenna and affecting the normal use of the top antenna of the device body. The metal director units included in the antenna accessory of the electronic device protective case are located outside the satellite antenna 103, and the ends of the metal director units do not exceed the antenna slot 106.

[0099] It can be understood that since there is a close relationship between the length of the metal director unit and the resonance it generates, when the resonance requirements are met, the requirement of not covering the antenna slot 106 can be satisfied by shortening the length of the metal director unit. In some embodiments, as Figure 15 shown, taking the first metal director unit 3 as an example, the first-stage metal director unit 3 includes a main branch 31, a first bent branch 32, and a second bent branch 33. The first bent branch 32 is connected to the left end of the main branch 31, and the second bent branch 33 is connected to the right end of the main branch 31. Both the first bent branch 32 and the second bent branch 33 extend from the end of the main branch 31 towards the middle of the main branch 31 after bending. And the main branch 31 is arranged outside the frame antenna of the device body. In some embodiments provided by the present disclosure, the main branch 31 is located outside the satellite antenna 103, and the end of the main branch 31 does not exceed the antenna slot formed by the satellite antenna 103. In this way, the length of the first metal director unit 3 can be extended through the settings of the first bent branch 32 and the second bent branch 33, without increasing the length of the first metal director unit 3. Subsequently, by matching the positional relationship between the main branch 31 and the antenna slot 106, the radiation influence on other top antennas can be avoided. Here, it is described by taking the example that the two ends of the main branch 31 of the first metal unit 3 are respectively configured with the first bent branch 32 and the second bent branch 33. In other embodiments, it may also be that only a bent branch is provided at one end of the main branch 31, such as only the first bent branch 32 or the second bent branch 33 is provided. The present disclosure does not limit this.

[0100] In some other embodiments, still taking the first metal director unit 3 as an example, as Figure 16 shown, a slot 34 is provided in the middle of the first metal director unit 3. The antenna accessory further includes a capacitor 8, and the capacitor 8 is electrically connected to the two end portions of the first metal director unit 3 where the slot 34 is formed respectively. That is, the two parts of the first metal director unit 3 disconnected by the slot 34 can be connected in series through the capacitor 8. In this way, the electrical length of the first metal director unit 3 can be increased through the setting of the capacitor 8, which is also beneficial to meeting the resonance requirement of the first metal director unit 3 without covering the antenna slot 106.

[0101] In still some other embodiments, still taking the first metal director unit 3 as an example, a slot 34 is provided in the middle of the first metal director unit 3. The antenna accessory further includes an inductor, and the inductor is electrically connected to the two end portions of the first metal director unit 3 where the slot 34 is formed respectively. That is, the two parts of the first metal director unit 3 disconnected by the slot 34 can be connected in series through the inductor. In this way, the electrical length of the first metal director unit 3 can be increased through the setting of the inductor, which is also beneficial to meeting the resonance requirement of the first metal director unit 3 without covering the antenna slot 106.

[0102] In the foregoing embodiments, only taking the first metal guiding unit 3 as an example, a solution for increasing the length of the metal guiding unit without increasing the width of the metal guiding unit is exemplarily described. In other embodiments, other metal guiding units may also be implemented with reference to the first metal guiding unit 3, which will not be elaborated here. Optionally, a bent branch and an electrically connected capacitor or inductor may also be provided in the same metal guiding unit, which can be specifically designed as required.

[0103] Another option is, as Figure 17 and Figure 18 shown, the antenna accessory may further include a clip 9, which is connected to the bracket 1. The clip can be detachably connected to the supporting device body, so that the setting of the clip is beneficial to matching device bodies of different specifications, such as a straight plate type device or a folding type device.

[0104] Based on the technical solution of the present disclosure, as Figure 19 shown, the present disclosure further provides a satellite alignment method, which may include the following steps:

[0105] In step 191, a communication instruction for establishing a communication connection with a target communication satellite is received.

[0106] In this embodiment, the communication instruction may be generated based on a trigger instruction when the user triggers the electronic device; or, the communication instruction may also be generated when the electronic device automatically detects that there is no operator signal.

[0107] In step 192, the identification unit 6 is identified.

[0108] In step 193, when the identification unit 6 is identified, satellite alignment is guided according to the first satellite alignment angle, and when the identification unit 6 is not identified, satellite alignment is guided according to the second satellite alignment angle.

[0109] In this embodiment, taking the device body in the foregoing embodiments as an example, as Figure 20 shown, when the maximum radiation direction angle of the electronic device (the gray-filled part in Figure 20 ) with the antenna accessory configured points to the satellite, it is the optimal satellite alignment angle. In fact, on this basis, the electronic device can also perform satellite alignment when rotating within the range of ±30° (within the range indicated by the dotted line) of the maximum radiation direction angle in pitch, and has good communication capabilities; while for the single device body without the antenna accessory (the white-filled part in Figure 20 ), as Figure 20As shown, there is a difference of about 20° between the maximum radiation direction angle of the single device body and the maximum radiation angle of the electronic device in the pitch direction. Therefore, if the satellite alignment angle of the single device body is adjusted based on the maximum radiation direction angle of the electronic device, theoretically when the maximum radiation angle is directly facing the satellite, there is actually a 20° difference between the maximum radiation angle and the satellite, which is very likely to lead to unsuccessful satellite alignment or poor communication ability.

[0110] Furthermore, whether the antenna accessory is configured or not will directly affect the relative position relationship between the device body and the identification unit 6. Therefore, the identification unit 6 for identifying the antenna accessory can be used to determine whether to adopt the optimal satellite alignment angle of the single device body or the optimal satellite alignment angle of the electronic device with the antenna accessory configured for guiding satellite alignment.

[0111] For example, assume that the antenna accessory is detachably connected to the device body. For example, the antenna accessory is assembled when satellite communication is needed, and the antenna accessory is disassembled when satellite communication is not needed. Then, when the antenna accessory is removed and in a state of communicating with the target satellite, since the identification unit 6 is far from the device body and the device body does not recognize the identification unit 6, aligning according to the second satellite alignment angle can be guiding satellite alignment according to the optimal satellite alignment angle of the device body; when the antenna accessory is assembled to the device body and in a state of communicating with the target satellite, the identification unit 6 is close to the device body, and at this time the device body can recognize the identification unit 6. At this time, aligning according to the first satellite alignment angle can be guiding satellite alignment according to the optimal satellite alignment angle of the electronic device with the antenna accessory configured.

[0112] In another embodiment, as Figure 2 and Figure 6 shown, the antenna accessory is always assembled to the device body, and when communication with the target satellite is not needed, the antenna accessory is stored on the back plate side of the device body, and when communication with the target satellite map is needed, the antenna accessory is switched to the outside of the device body. Obviously, in these two cases, the relative position between the identification unit 6 and the device body changes, and in order to adapt to this change in relative position, the identification unit 6 and the device body are wirelessly connected.

[0113] Among them, in the Figure 6 shown state, the antenna accessory is arranged close to the electronic components inside the device body. At this time, the antenna accessory is stored and cannot participate in the communication with the target satellite, and in this state, the signal connection strength between the identification unit 6 and the device body is relatively large; while in the Figure 2 shown state, the antenna accessory can participate in the communication with the target satellite, and in this state, the signal connection strength between the identification unit 6 and the device body is relatively small.

[0114] Therefore, when the signal connection strength between the identification unit 6 and the device body is greater than or equal to a preset threshold, it is determined that the identification unit 6 is recognized, and the satellite alignment according to the first satellite alignment angle can be guiding the satellite alignment according to the best satellite alignment angle of the device body; when the signal connection strength between the identification unit 6 and the device body is less than the preset threshold, it is determined that the identification unit is not recognized, and the satellite alignment according to the second satellite alignment angle can be guiding the satellite alignment according to the best satellite alignment angle of the electronic device when the antenna accessory is configured.

[0115] Of course, in some other examples, it can also be that when the signal connection strength between the identification unit 6 and the device body is greater than or equal to a preset threshold, it is determined that the identification unit 6 is recognized, and the satellite alignment according to the first satellite alignment angle can be guiding the satellite alignment according to the best satellite alignment angle of the electronic device when the antenna accessory is configured. When the signal connection strength between the identification unit 6 and the device body is less than the preset threshold, it is determined that the identification unit 6 is not recognized, and the satellite alignment according to the second satellite alignment angle can be guiding the satellite alignment according to the best satellite alignment angle of the device body.

[0116] Corresponding to the foregoing embodiments of the satellite alignment method, the present disclosure also provides an embodiment of a satellite alignment device.

[0120] The determination module 203 guides the satellite alignment according to the first satellite alignment angle when the signal strength of the communication signal is within a first range, and guides the satellite alignment according to the second satellite alignment angle when the strength of the communication signal is within a second range.
