[0057] 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.

[0059] 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 determining".

[0060] 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 is left-handed circular polarization or right-handed circular polarization. Therefore, generally, an external four-arm helical antenna is configured for an electronic device, so that the antenna pattern points to the direction pointed by the antenna, that is, points to the zenith direction, and at the same time, the circular polarization gain is relatively high, meeting the satellite call requirements.

[0061] 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 for the electronic device, and it will also increase the thickness and weight of the electronic device. For portable electronic devices, it goes against the original intention of users.

[0062] Based on this, the present disclosure provides an antenna accessory. This antenna accessory can be connected to the electronic device when the electronic device needs to be used, and can be disassembled when not needed, 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.

[0063] Specifically, Figure 1is a schematic structural diagram of an antenna accessory shown according to an exemplary embodiment. 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, which can be designed as needed specifically, and the present disclosure does not limit this.

[0064] For example, as Figure 2 shown, the present disclosure also provides an electronic device. The electronic device includes a device body, and the device body includes a housing 101, a middle frame 102, and an antenna accessory. The bracket 1 of the antenna accessory can be detachably connected to the housing 101. When the device body needs to communicate with the target communication satellite, the bracket 1 can be connected to the housing 101. After the communication is over, in order to facilitate carrying the device body, the antenna accessory can be disassembled. And, through the connection between the bracket 1 and the housing 101, the metal director unit can be disposed adjacent to the satellite antenna 103, so that the circular polarization gain peak can be increased and the signal strength can be enhanced by the action of the metal director unit.

[0065] Part of the frame segment of the middle frame 102 forms the satellite antenna 103 of the device body. When the device body 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 is generated by coupling 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 resonance generated by the coupling of the first metal director unit 3, the second metal director unit 4, and the third metal director unit 5 respectively. 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, that is, H3 = (0.05 - 0.25)λ. In other words, it can be understood that when multiple metal director units are arranged on the non-metallic substrate 2, when the metal director units generate resonance through coupling, 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. Wherein, 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.

[0066] 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, as Figure 4 shown is the left-handed radiation pattern of a single device body in free space, Figure 5 and Figure 4 is the left-handed radiation 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 device body in the zenith direction is +0.2 dB. When the antenna accessory is configured, at the position indicated by the small triangular mark to the left of the right-side indicator bar in

[0067] 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 main body communicates with a satellite, the antenna pattern of the satellite antenna 103 faces the zenith direction of the antenna, enabling the user to point at the satellite with 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 beneficial to implement communication methods for sending pictures or voice messages.

[0068] In the foregoing embodiment, an example is given where the antenna accessory includes three metal director units, namely the first metal director unit 3, the second metal director unit 4, and the third metal director unit 5. In other embodiments, the antenna accessory may also include a single metal director unit, or multiple metal director units in 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 of the circular polarization gain improvement. 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 metal director units can be greater than or equal to 1 and less than or equal to 4.

[0069] When the antenna accessory includes multiple metal director units, during coupling, the multiple metal director units are arranged side by side and at intervals. In other words, when the satellite antenna 103 communicates with a target communication satellite, the multiple metal director units are arranged at intervals along a preset direction, thereby facilitating an increase in the amount of the circular gain peak improved by the antenna accessory. 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, when 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. Taking Figure 1 and Figure 2 as an 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-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.

[0070] 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 the 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.

[0071] For example, taking the Tiantong-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 point of Tiantong-1 is between 1980 MHz and 2200 MHz. Thus, the lengths of the metal director units are 0.35 - 0.5 times the wavelength corresponding to any resonant frequency point 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 in the length range of 40 mm - 68 mm. When the dielectric constant of the dielectric environment where the metal director unit is located is different or the setting method is different, the length of the metal director unit can be adaptively adjusted according to the conversion relationship and a limited number of experiments. For example, when the first metal director unit 3, the second metal director unit 4, and the third metal director unit 5 are in a dielectric environment with a dielectric constant of 3.5, and the non-metal substrate 2 covers the metal director unit on one side, then L1, L2, and L3 are respectively in 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 unit 3, the second metal director unit 4, and the third metal director unit 5 are in a dielectric environment with a dielectric constant of 3.5, and the non-metal substrate 2 covers the metal director unit on both sides, then L1, L2, and L3 are respectively in the range of 36 mm - 61 mm, and preferably, L1, L2, and L3 can be 40 mm respectively.

[0072] 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 of the target communication satellite. For example, the distance H1 between the first metal director element 3 and the second metal director element 4 is H1 = (0.05 - 0.25)λ, and the distance H2 between the second metal director element 4 and the third metal director element 5 is H2 = (0.05 - 0.25)λ. Here, H1 and H2 can be equal or not, and can be specifically designed as needed. Where λ is the wavelength corresponding to the operating frequency of the target communication satellite. Taking the resonant frequency of 2200 MHz as an example, the corresponding operating wavelength is 136 mm. Therefore, L1, L2, and L3 in free space are respectively in the length range of 4 mm - 40 mm. For example, if 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-metallic substrate 2 covers the metal director elements on one side, then H1 and H2 are respectively in the range of 1 mm - 36 mm, and preferably H1 and H2 can be 20 mm respectively; for another example, if 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-metallic substrate 2 covers the metal director elements on both sides, then H1 and H2 are respectively in the range of 0.5 mm - 35 mm, and preferably H1 and H2 can be 18 mm respectively.

[0073] In each of the above embodiments, the non-metallic substrate 2 and the bracket 1 can be movably connected, so that the non-metallic substrate 2 can switch between the initial position and the target position relative to the bracket 1. Since the first metal director element 3, the second metal director element 4, and the third metal director element 5 are all attached to the non-metallic substrate 2, when the non-metallic substrate 2 moves relative to the bracket 1, the first metal director element 3, the second metal director element 4, and the third metal director element 5 will also switch positions accordingly. When the non-metallic substrate 2 is in the target position, the first metal director element 3, the second metal director element 4, and the third metal director element 5 are used to generate resonance by coupling with the device body.

[0074] Based on this, when the antenna accessory is connected to the device body through the bracket 1, the position relationship can be switched relative to the device body by the movement of the non-metallic substrate 2 relative to the bracket 1, which is beneficial to realizing the accommodation of the non-metallic substrate 2 and the metal director elements provided on the non-metallic substrate 2.

[0075] For example, when the non-metallic substrate 2 is in Figure 2 the target position, the first metal director element 3, the second metal director element 4, and the third metal director element 5 are all outside the device body, that is, all the metal director elements provided on the non-metallic substrate 2 are outside the housing 101; and when the non-metallic substrate 2 is in Figure 6When in the initial position shown, the non-metallic substrate 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 facilitate the storage of the electronic device equipped with the antenna accessory. Among them, as Figure 6 and Figure 7 shown, the bracket 1 and the non-metallic substrate 2 can be rotatably connected. For example, the rotating shaft can be arranged perpendicular to the paper surface, and the non-metallic substrate 2 rotates 180° along the paper surface to switch from the initial position to the target position; or the rotating shaft can also be arranged parallel to the paper surface, and the non-metallic substrate 2 can be flipped 180° to switch from the initial position to the target position; optionally, the bracket 1 and the non-metallic substrate 2 can also be slidably connected, and the non-metallic substrate 2 slides relative to the bracket 1 to switch from the initial position to the target position.

[0076] 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 Figure 1 shown in, the telescopic direction of the bracket 1 is the up-and-down direction in the figure. Based on this, as Figure 7 shown, when the non-metallic substrate 2 switches from the Figure 6 shown initial position to the target position relative to the bracket 1, but there is a situation where the metal director unit is 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 push the metal director unit out of the housing 101, that is, it can be switched from the Figure 7 shown state to the Figure 2 shown state; 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. Among them, 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 spaced apart.

[0077] In some embodiments, 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, and achieve conformal in the two, which can reduce the visually obtrusive effect caused by the configuration of the antenna accessory. For example, the housing 101 can include a body, an opening, and a support outer ring 104 surrounding the opening. The device body further includes a camera protection sheet 105, and the camera protection sheet 105 is connected inside the support outer ring 104. When the non-metallic substrate 2 is in the initial position, as Figure 6As shown, the non-metallic substrate 2 is stacked outside the camera protection sheet 105, and the outer peripheral shape of the non-metallic substrate 2 matches the inner peripheral shape of the support outer ring 104.

[0078] In the above embodiments, the non-metallic substrate 2 is set as a square structure for illustration. In other embodiments, such as Figures 8 - 11 As shown, the non-metallic substrate 2 can also be set as a circular structure. Similarly, as Figure 9 As 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 configuring the antenna accessory. In the foregoing embodiments, the metal director unit is taken as a strip structure for illustration. In other embodiments, such as Figure 8 As shown, the metal director unit can also be arc-shaped. 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 arc-shaped, 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.

[0079] Similarly, in Figures 8 - 11 In the shown embodiment, the bracket 1 can also be movably connected to the non-metallic substrate 2. Through the movement of the non-metallic substrate 2 relative to the bracket 1, the switching between the initial position shown in Figure 9 and the target position shown in Figure 10 is realized. The relevant solutions for the initial position and the target position can refer to the foregoing embodiments and will not be elaborated here. Similarly, the bracket 1 can be a telescopic bracket. Through the telescoping of the telescopic bracket, the switching between the state shown in Figure 10 and the state shown in Figure 11 can be realized, that is, all the metal director units located on the non-metallic substrate 2 can be ejected out of the housing. The relevant solutions can refer to the foregoing embodiments and will not be elaborated here.

[0080] Based on the technical solution of the present disclosure, an electronic device protection case is further provided. The electronic device protection case includes a protection case body and the antenna accessory described in any one of the foregoing embodiments. Wherein, the protection case body can fully wrap or semi-wrap the device body. The present disclosure also provides an electronic device, which can include a device body and the electronic device protection case described in any one of the foregoing embodiments.

[0081] Referring to the technical solution for connecting the antenna accessory to the device body, when the antenna accessory is assembled with the electronic device protective case, the non-metallic base body 2 is movably connected to the bracket 1, so that the non-metallic base body 2 can switch between the initial position and the target position relative to the bracket 1. Among them, when the non-metallic base body 2 is in the target position, the metal director unit of the antenna accessory is located outside the protective case body. Specifically, the positional relationship between the metal director unit and the protective case body depends on the position of the satellite antenna of the device body that is matched with the protective case body, and finally the metal director unit is located outside the satellite antenna; when the non-metallic base body 2 is in the initial position, the non-metallic base body 2 is overlapped with the protective case body, so as to reduce the occupied area of the electronic device protective case.

[0082] The protective case body includes a camera protection area. When the protective case body wraps the device body, the camera protection area covers the rear camera area of the device body. Further, when the non-metallic base body 2 is in the initial position, the non-metallic base body 2 covers the outside of the camera protection area. Especially when the camera protection area usually adopts a slightly concave structure form, the non-metallic base body 2 can be received through the camera protection area to improve the visual effect.
