[0001] This disclosure relates to the field of communication technology, and more particularly to a protective sleeve and electronic device assembly. Background Technology

[0002] With the gradual development of electronic devices such as smartphones, people's communication needs have expanded beyond everyday scenarios. The demand for communication in extreme environments such as deserts, oceans, and plateaus is increasing, with a growing expectation for emergency calls even in these conditions. Satellite phones are typically used for communication in extreme environments; however, they are suitable only for a small group of people with a strong need for satellite communication and offer only basic satellite communication functionality, resulting in limited usage scenarios and communication capabilities. Summary of the Invention

[0004] According to a first aspect of the present disclosure, a protective sleeve is provided, comprising:

[0005] Protective cover frame, used to fit over the side frame of electronic devices;

[0006] An antenna radiator is disposed on the top edge of the protective case frame; wherein the top edge of the protective case frame is used to contact the top frame of the electronic device;

[0007] The antenna coupling stub is spaced apart from the antenna radiator and positioned on the top frame, and can couple with the antenna radiator to work together in the satellite frequency band.

[0008] In some embodiments, the antenna radiator includes: a first radiator and a second radiator;

[0009] The first radiator and the second radiator are staggered in the width direction of the top frame, and the antenna patterns of the antenna radiators are concentrated in the width direction of the top frame.

[0010] In some embodiments, the first radiator and the second radiator are offset from each other along the length direction of the top border, and the length direction of the top border is perpendicular to the width direction of the top border.

[0011] In some embodiments, the first radiator and the second radiator are located in the same plane in the thickness direction of the top frame, and the thickness direction of the top frame is perpendicular to the width direction of the top frame.

[0012] In some embodiments, the first radiator forms a first orthographic projection on the top frame of the electronic device;

[0013] The second radiator forms a second orthographic projection on the top frame of the electronic device;

[0014] Both the first orthographic projection and the second orthographic projection are located between the two antenna gaps in the top frame of the electronic device.

[0015] In some embodiments, the antenna coupling stub includes:

[0016] The first coupling branch is distributed at intervals along the thickness direction of the top frame with the first radiator, and the third orthographic projection formed on the first radiator is at least partially coincident with the first radiator.

[0017] The second coupling branch is distributed at intervals along the thickness direction of the top frame with the second radiator, and the fourth orthographic projection formed on the second radiator is at least partially coincident with the second radiator.

[0018] In some embodiments, the first coupling branch extends in the width direction of the top border to the third orthographic projection beyond the first radiator;

[0019] And / or,

[0020] The second coupling branch extends in the width direction of the top border to the fourth orthographic projection beyond the second radiator.

[0021] In some embodiments, the orthographic projection of the first coupling stub onto the top frame of the electronic device at least partially covers an antenna gap in the top frame of the electronic device;

[0022] And / or,

[0023] The orthographic projection of the second coupling stub onto the top frame of the electronic device at least partially covers another of the antenna gaps in the top frame of the electronic device.

[0024] In some embodiments, the distance from the antenna coupling stub to the top frame of the electronic device is greater than the distance from the antenna radiator to the top frame of the electronic device.

[0025] In some embodiments, the protective sleeve includes:

[0026] A first radio frequency chip is disposed in the protective sleeve;

[0027] The first connector is disposed on the protective sleeve, with one end connected to the antenna radiator and the other end connected to the first radio frequency chip;

[0028] or,

[0029] The second connector is disposed on the protective sleeve, with one end connected to the antenna radiator and the other end connected to the second radio frequency chip of the electronic device through the satellite communication interface of the electronic device.

[0030] In some embodiments, both the antenna radiator and the antenna coupling stub include conductive sheets.

[0031] In some embodiments, the satellite frequency band is between 1.98 GHz and 2.2 GHz.

[0032] According to a second aspect of the present disclosure, an electronic device component is provided, comprising:

[0036] In this embodiment, the antenna radiator and antenna coupling stub are spaced apart and positioned on the top edge of the protective sleeve frame. The antenna coupling stub can couple with the antenna radiator and operate together in the satellite frequency band. Thus, the protective sleeve of this embodiment can both protect electronic equipment and enable satellite communication, achieving a dual function and enriching the protective sleeve's functionality.

[0037] Furthermore, in this embodiment, the antenna radiator and antenna coupling stub operating in the satellite frequency band are both located on the top edge of the protective case. This ensures that the antenna radiator and antenna coupling stub are not obstructed when the electronic device with the protective case is held in hand, thereby improving the antenna performance of the protective case operating in the satellite frequency band. Simultaneously, the antenna coupling stub and antenna radiator, after coupling, can work together in the satellite frequency band, thus increasing the radiation area and further improving the antenna performance of the protective case operating in the satellite frequency band.

[0057] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0058] This disclosure proposes a protective case that can be used with electronic devices to enable satellite communication in extreme communication scenarios such as deserts, oceans, and plateaus.

[0059] Figure 1 This is a top view illustrating a protective sleeve fitted over an electronic device according to an exemplary embodiment. Figure 2 This is a side view of an antenna radiator in a protective sleeve according to an exemplary embodiment. Figure 3 This is a side view of an antenna radiator and antenna coupling stub in a protective sleeve according to an exemplary embodiment. Figure 1 , Figure 2 and Figure 3 As shown, the protective case includes:

[0060] The protective cover frame 100 is used to cover the side frame of the electronic device 200;

[0061] An antenna radiator 300 is disposed on the top edge 101 of the protective cover frame 100; wherein the top edge 101 of the protective cover frame 100 is used to contact the top frame of the electronic device.

[0062] The antenna coupling stub 400 is disposed at a distance from the antenna radiator 300 on the top frame 101, and can work together with the antenna radiator 300 in the satellite frequency band after coupling.

[0063] In this embodiment of the disclosure, the protective case can be used to protect electronic devices and can also be used for satellite communication through the antenna radiator set on the protective case, that is, the protective case is a two-in-one protective case.

[0064] The aforementioned protective case includes a protective case frame. This protective case frame contacts the side frame of the electronic device and is used to protect the side frame of the electronic device. Here, as... Figure 1 As shown, the protective case frame 100 can be formed by connecting the top frame 101, the side frame 102 and the bottom frame (not shown in the figure).

[0065] It should be noted that the protective case may also include a protective case back panel. The protective case frame may be formed by extending the protective case back panel, and the protective case back panel and the protective case frame are connected to form a space for accommodating electronic devices.

[0066] Thus, when the protective case also includes a back panel, the back panel contacts the back frame of the electronic device. In addition to protecting the side frame of the electronic device through the frame of the protective case, the back panel can also protect the back frame of the electronic device.

[0067] It should be noted that the back panel and frame of the protective case do not obstruct the screen of the electronic device. In other words, the protective case does not block the screen of the electronic device. Thus, the protective case not only protects the electronic device and allows it to operate on satellite frequencies, but also enables the electronic device to display information more effectively.

[0068] The aforementioned antenna radiator can establish a communication connection with a satellite, enabling electronic devices encased in a protective case to communicate with other electronic devices via satellite relay communication signals.

[0069] It should be noted that the antenna radiator can be a circularly polarized antenna radiator. This can reduce polarization distortion loss caused by the ionospheric Faraday rotation effect and improve the quality of satellite communication.

[0070] For example, the antenna radiator may include a sky-connecting antenna radiator, a four-arm spiral antenna radiator, an array antenna radiator, etc., and the embodiments disclosed herein do not limit this.

[0071] The aforementioned antenna radiator can be connected to the first radio frequency chip or the second radio frequency chip of the electronic device inside the protective sleeve, and operates in the satellite frequency band under the excitation of the feed signal output by the first radio frequency chip or the second radio frequency chip.

[0072] It should be noted that the antenna radiator may include at least one radiator. In the case where the antenna radiator includes multiple radiators, all of them may operate in the satellite frequency band under the excitation of the feed signal.

[0073] The aforementioned antenna radiator and antenna coupling stub are all located on the top frame. Here, when the electronic device is fitted into the protective case frame, the top frame of the protective case is in contact with the top frame of the electronic device. This ensures that even when holding the electronic device with the protective case, the antenna radiator and antenna coupling stub inside the protective case will not be obstructed, thus improving the antenna performance of the antenna inside the protective case when operating in the satellite frequency band.

[0074] It should be noted that the antenna radiator and the antenna coupling stub can be formed of different materials. In some embodiments, both the antenna radiator and the antenna coupling stub are formed of flexible circuit boards.

[0075] In other embodiments, both the antenna radiator and the antenna coupling stub include conductive sheets.

[0076] In other words, in the embodiments of this disclosure, both the antenna radiator and the antenna coupling stub can be formed from conductive sheets.

[0077] In this embodiment of the disclosure, the conductive sheets can all be formed by laser direct forming (LDS) technology, and this embodiment of the disclosure does not limit this.

[0078] In this embodiment of the present disclosure, the antenna coupling stub is spaced apart from the antenna radiator and is capable of coupling with the antenna radiator.

[0079] Here, the relative positions between the antenna coupling stub and the antenna radiator can be set according to the actual situation to achieve coupling between the antenna coupling stub and the antenna radiator. This disclosure does not limit this.

[0080] For example, the antenna radiator and antenna coupling stub may be spaced apart on the top frame along the thickness direction of the top frame; or, the antenna radiator and antenna coupling stub may be spaced apart on the top frame along the length direction of the top frame; or, the antenna radiator and antenna coupling stub may be spaced apart on the top frame along the width direction of the top frame.

[0081] In this embodiment, the orthographic projection of the antenna coupling stub onto the antenna radiator at least partially coincides with the antenna radiator. This allows for better coupling between the antenna coupling stub and the antenna radiator.

[0082] The aforementioned antenna radiator and antenna coupling stub work together in the satellite frequency band after coupling. In other words, a satellite antenna is installed in the protective sleeve, enabling satellite communication by operating in the satellite frequency band, making it suitable for extreme communication scenarios such as deserts, oceans, and plateaus.

[0083] In some embodiments, the satellite frequency band may include between 1.98 GHz and 2.2 GHz.

[0084] Here, the satellite frequency band transmitted by the protective case may be between 1.98 GHz and 2.01 GHz, and the satellite frequency band received by the protective case may be between 2.17 GHz and 2.2 GHz.

[0085] Of course, the satellite frequency band in which the protective case of this disclosure operates may also include 2GHz to 4GHz, and this disclosure does not limit this.

[0086] For example, Figure 4 This is a schematic diagram of a Tiantong satellite phone according to an exemplary embodiment. For example... Figure 4As shown, the Tiantong Satellite Phone 500 is typically used for satellite communication in extreme communication scenarios such as deserts, oceans, and plateaus. For example, during navigation or exploration, the external helical antenna 501 of the Tiantong Satellite Phone 500 provides a superior antenna environment, enabling omnidirectional radiation and thus improving antenna performance. However, the Tiantong Satellite Phone is suitable for a small group of people with strong demand for satellite communication, and it only provides a single satellite communication function, resulting in a limitation in both usage scenarios and communication capabilities.

[0087] Based on this, the present disclosure proposes that the antenna radiator and the antenna coupling stub be spaced apart in the top frame of the protective sleeve frame, and that the antenna coupling stub can work together with the antenna radiator in the satellite frequency band after coupling. Thus, the protective sleeve of the present disclosure can both protect electronic equipment and enable satellite communication, achieving a dual function and enriching the functionality of the protective sleeve.

[0088] Furthermore, in this embodiment, the antenna radiator and antenna coupling stub operating in the satellite frequency band are both located on the top edge of the protective case. This ensures that the antenna radiator and antenna coupling stub are not obstructed when the electronic device with the protective case is held in hand, thereby improving the antenna performance of the protective case operating in the satellite frequency band. Simultaneously, the antenna coupling stub and antenna radiator, after coupling, can work together in the satellite frequency band, thus increasing the radiation area and further improving the antenna performance of the protective case operating in the satellite frequency band.

[0089] In some embodiments, such as Figure 2 and Figure 3 As shown, the antenna radiator includes: a first radiator 301 and a second radiator 302;

[0090] The first radiator 301 and the second radiator 302 are staggered in the width direction A of the top frame 101, and the antenna patterns of the antenna radiators are concentrated in the width direction A of the top frame.

[0091] In this embodiment of the present disclosure, the antenna radiator includes a first radiator and a second radiator. When the protective sleeve includes a first connector, the end of the first radiator near the second radiator and the end of the second radiator near the first radiator can both be connected to the first connector to enable operation in the satellite frequency band under the excitation of the feed signal.

[0092] When the protective sleeve includes a second connector, the end of the first radiator near the second radiator and the end of the second radiator near the first radiator can both be connected to the second connector to enable operation in the satellite frequency band under the excitation of the power supply signal.

[0093] It should be noted that when the antenna radiator includes a conductive sheet, the first radiator and the second radiator can be composed of conductive sheets disposed at different positions on the top frame.

[0094] In this embodiment of the present disclosure, the first radiator and the second radiator are staggered in the width direction of the top frame, so that the antenna radiation patterns of the antenna radiators are concentrated in the width direction of the top frame.

[0095] For example, Figure 5 This is a three-dimensional perspective view of a left-handed circularly polarized antenna radiator according to an exemplary embodiment of the present disclosure. Figure 5 As shown, the first radiator and the second radiator are staggered in the width direction A of the top frame, which can reduce the coupling between the first radiator and the second radiator, so that the circular polarization pattern of the antenna radiator is concentrated in the width direction A of the top frame.

[0096] In this embodiment of the disclosure, when the protective case is fitted over the electronic device, the width direction of the top edge of the protective case is the same as the thickness direction of the electronic device. That is, the first radiator and the second radiator can be staggered along the thickness direction of the electronic device.

[0097] For example, an electronic device includes a mobile phone, and a first radiator and a second radiator may be offset along the thickness direction of the mobile phone.

[0098] It should be noted that the first radiator and the second radiator are staggered along the thickness direction of the electronic device, which may include: the top frame of the electronic device may be divided into different first and second regions along the thickness direction of the electronic device; the orthographic projection of the first radiator onto the top frame of the electronic device may be located in the first region; and the orthographic projection of the second radiator onto the top frame of the electronic device may be located in the second region.

[0099] Here, the first region and the second region can constitute the surface area of ​​the top frame of the electronic device facing the top edge of the protective case. The first region and the second region can also be two regions of equal area. That is, the surface area can be divided in half along the thickness direction of the electronic device into an upper first region and a lower second region, such that the orthographic projection of the first radiator onto the top frame of the electronic device can be located in the upper first region; and the orthographic projection of the second radiator onto the top frame of the electronic device can be located in the lower second region.

[0100] In this embodiment of the disclosure, the screen of the electronic device is disposed in the thickness direction of the electronic device, and the first radiator and the second radiator are offset in the thickness direction of the electronic device. Therefore, the antenna radiation pattern of the antenna radiators in this embodiment of the disclosure can be concentrated in the display direction of the screen and in the rear direction of the screen, which is opposite to the display direction, thereby widening the angle and range of the antenna radiators toward the star.

[0101] For example, Figure 6 This is a two-dimensional diagram of the left-hand circular polarization of the antenna radiator of this disclosure, illustrated according to an exemplary embodiment. Figure 6 As shown, the horizontal axis represents the pitch angle (phi), and the vertical axis represents the azimuth angle (theta).

[0102] This embodiment of the disclosure, by setting the first radiator and the second radiator to be offset in the width direction of the top border, enables the phi region between 0 and 40 degrees and theta region between -150 degrees and +150 degrees to have strong radiation pattern coverage.

[0103] Thus, in this embodiment of the present disclosure, the first radiator and the second radiator are staggered in the width direction of the top frame, which can meet the requirements of satellite communication pattern coverage between -30 degrees and +30 degrees, and realize the widening of the antenna pattern coverage range.

[0104] In some embodiments, such as Figure 2 and Figure 3 As shown, the first radiator 301 and the second radiator 302 are staggered along the length direction B of the top frame, and the length direction of the top frame is perpendicular to the width direction of the top frame.

[0105] In this embodiment of the disclosure, when the protective case is fitted over the electronic device, the length direction of the top edge of the protective case is the same as the width direction of the electronic device. That is, the first radiator and the second radiator can be staggered along the width direction of the electronic device.

[0106] For example, an electronic device includes a mobile phone, and a first radiator and a second radiator may be offset along the width direction of the mobile phone.

[0107] It should be noted that the first radiator and the second radiator are staggered along the width direction of the electronic device, which may include: the top frame of the electronic device may be divided into different third and fourth regions along the width direction of the electronic device; the orthographic projection of the first radiator onto the top frame of the electronic device may be located in the third region; and the orthographic projection of the second radiator onto the top frame of the electronic device may be located in the fourth region.

[0108] It is understandable that by setting the first and second radiators offset along the width of the electronic device, the radiating area along the width of the electronic device can be increased, thereby expanding the radiation range of the antenna radiator.

[0109] In some embodiments, such as Figure 2 and Figure 3As shown, the first radiator 301 and the second radiator 302 are located on the same plane in the thickness direction (not shown in the figure) of the top frame, and the thickness direction of the top frame is perpendicular to the width direction of the top frame.

[0110] The thickness direction of the aforementioned top border is perpendicular to the plane containing the length direction and width direction of the top border.

[0111] In this embodiment of the disclosure, when the protective case is fitted over the electronic device, the thickness direction of the top edge of the protective case is the same as the length direction of the electronic device. That is, the first radiator and the second radiator can be located on the same plane along the length direction of the electronic device.

[0112] For example, the width direction of the electronic device can be referred to as the X direction, the length direction as the Y direction, and the thickness direction as the Z direction. The first radiator and the second radiator are located in the same plane in the Y direction. The first radiator and the second radiator are staggered in both the X and Z directions.

[0113] Here, when both the first radiator and the second radiator are conductive sheets, both the first radiator and the second radiator can be parallel to the XZ plane.

[0114] It is understandable that the first and second radiators are positioned on the same plane in the thickness direction of the top frame, which allows for better placement of the antenna radiators on the protective cover and facilitates manufacturing.

[0115] In some embodiments, such as Figure 2 and Figure 8 As shown, the first radiator 301 forms a first orthographic projection on the top frame 201 of the electronic device;

[0116] The second radiator 302 forms a second orthographic projection on the top frame 201 of the electronic device;

[0117] Both the first orthographic projection and the second orthographic projection are located between the two antenna gaps 202 of the top frame 201 of the electronic device.

[0118] In this embodiment of the disclosure, the orthographic projection of the antenna radiator onto the top frame of the electronic device is located between the two antenna gaps in the top frame of the electronic device.

[0119] The projection rays corresponding to the first orthographic projection and the second orthographic projection are both perpendicular to the top frame.

[0120] It should be noted that both the first and second orthographic projections are located between the two antenna slots on the top frame of the electronic device. Furthermore, the first and second radiators are staggered along the width of the electronic device. Therefore, in the width direction of the electronic device, the sum of the lengths of the first and second orthographic projections can be less than or equal to the distance between the two antenna slots. This allows for the antenna radiators to be positioned to the maximum extent possible along the width direction of the electronic device.

[0121] It is understandable that the projection of the antenna radiator onto the top frame of the electronic device lies between the two antenna gaps in the top frame. This reduces the impact on the top frame antenna of the electronic device when the antenna radiator is operating in the satellite frequency band, thereby improving the performance of the top frame antenna in the electronic device.

[0122] In some embodiments, such as Figure 3 As shown, the antenna coupling stub 400 includes:

[0123] The first coupling branch 401 is distributed at intervals with the first radiator 301 along the thickness direction of the top frame 101 on the top frame 101, and the third orthographic projection formed on the first radiator 301 at least partially coincides with the first radiator 301.

[0124] The second coupling branch 402 is distributed at intervals along the thickness direction of the top frame 101 with the second radiator 302, and the fourth orthographic projection formed on the second radiator 302 at least partially coincides with the second radiator 302.

[0125] In this embodiment of the disclosure, the first coupling stub can be coupled with the first radiator to jointly transmit and receive satellite frequency bands, and the second coupling stub can be coupled with the second radiator to jointly transmit and receive satellite frequency bands.

[0126] It should be noted that the first coupling branch and the second coupling branch can be staggered in the thickness direction, length direction and width direction of the top border.

[0127] Of course, the first coupling branch and the second coupling branch can also be located on the same plane in the thickness direction of the top border, and staggered in both the length direction and the width direction of the top border.

[0128] It is understandable that by setting a first coupling branch corresponding to the first radiator and a second coupling branch corresponding to the second radiator, the radiation area can be increased to the maximum extent by setting multiple coupling branches, thereby improving the performance of the protective sleeve in the satellite frequency band.

[0129] In some embodiments, such as Figure 3As shown, the first coupling branch 401 extends in the width direction A of the top frame to the third orthographic projection beyond the first radiator 301;

[0130] And / or,

[0131] The second coupling branch 402 extends in the width direction A of the top frame to the fourth orthographic projection beyond the second radiator 302.

[0132] In this embodiment of the disclosure, the antenna coupling stub may extend in the width direction of the top frame, such that the orthographic projection of the antenna coupling stub onto the antenna radiator extends beyond the antenna radiator in the width direction of the top frame.

[0133] It should be noted that the first coupling branch extending in the width direction of the top border to the point where the third orthographic projection exceeds the first radiator may include: the first coupling branch extending in a first direction in the width direction of the top border to the point where the third orthographic projection exceeds the first radiator in the first direction; it may also include: the first coupling branch extending in a second direction in the width direction of the top border to the point where the third orthographic projection exceeds the first radiator in the second direction.

[0134] The first direction and the second direction are opposite directions in the width direction of the top border.

[0135] In this embodiment of the disclosure, the second coupling branch extending in the width direction of the top border to the point where its fourth orthographic projection exceeds the second radiator may include: the second coupling branch extending in a first direction in the width direction of the top border to the point where its fourth orthographic projection exceeds the second radiator in the first direction; it may also include: the second coupling branch extending in a second direction in the width direction of the top border to the point where its fourth orthographic projection exceeds the second radiator in the second direction.

[0136] For example, Figure 7 This is a left-handed circularly polarized two-dimensional diagram extending in the width direction of the top border of the protective sleeve of this disclosure, illustrated according to an exemplary embodiment. For example... Figure 7 As shown, the horizontal axis represents the pitch angle (phi), and the vertical axis represents the azimuth angle (theta).

[0137] Compared to Figure 6 Theta shown Figure 7 In the case of phi, which is located in the range of 0 to 360 degrees, the θ has better radiation pattern coverage in the range of 0 to 35 degrees.

[0138] It is understandable that by extending the first and second coupling branches along the width direction of the top border, the coverage of the protective sleeve's directional pattern in the width direction of the top border can be expanded.

[0139] In some embodiments, such as Figure 8 As shown, the orthographic projection of the first coupling stub 401 onto the top frame 201 of the electronic device at least partially covers an antenna slot 202 of the top frame 201 of the electronic device.

[0140] And / or,

[0141] The orthographic projection of the second coupling stub 402 onto the top frame 201 of the electronic device at least partially covers another antenna slit 202 of the top frame 201 of the electronic device.

[0142] The orthographic projection formed by the aforementioned first coupling stub at least partially covers one antenna gap. In other words, the first coupling stub can be positioned across the antenna gap.

[0143] The orthographic projection formed by the aforementioned second coupling stub at least partially covers another antenna gap. In other words, the second coupling stub can also be positioned across the antenna gap.

[0144] In this embodiment of the disclosure, the provision of a first coupling stub and a second coupling stub across the antenna gap maximizes the radiation area of ​​the antenna coupling stub and improves the antenna performance of the protective sleeve operating in the satellite frequency band. For example, it can improve the antenna gain of the protective sleeve operating in the satellite frequency band.

[0145] For example, Figure 9 This is a left-handed circularly polarized two-dimensional diagram of a protective sleeve without antenna coupling stubs, according to an exemplary embodiment. Figure 9 As shown, the horizontal axis represents the elevation angle (phi), and the vertical axis represents the azimuth angle (theta). The simulation gain of the protective sleeve without antenna coupling stubs is -2.7 dBic.

[0146] Figure 10 This is a two-dimensional diagram of left-hand circular polarization of an antenna coupling stub across a gap in a protective sleeve, as illustrated in an exemplary embodiment. Figure 10 As shown, the horizontal axis represents the elevation angle (phi), the vertical axis represents the azimuth angle (theta), and the simulation gain of the antenna coupling stub with cross-slits in the protective sleeve is -1.5dbic.

[0147] As can be seen, by incorporating antenna coupling stubs across the gaps within the protective sleeve, the gain of the protective sleeve operating in the satellite band can be increased by 1.2 dBic. This improves the antenna performance of the protective sleeve operating in the satellite band.

[0148] In some embodiments, such as Figure 8 As shown, the distance from the antenna coupling stub 400 to the top frame 201 of the electronic device is greater than the distance from the antenna radiator 300 to the top frame 201 of the electronic device.

[0149] In other words, the antenna coupling stub is located on the side of the top frame of the electronic device away from the antenna radiator. This reduces the impact of the top frame antenna on the antenna coupling stub, allowing for better coupling between the antenna coupling stub and the antenna radiator, thus improving the antenna performance of the protective sleeve operating in the satellite band.

[0150] In some embodiments, the protective sleeve includes:

[0151] A first radio frequency chip is disposed in the protective sleeve;

[0152] The first connector is disposed on the protective sleeve, with one end connected to the antenna radiator and the other end connected to the first radio frequency chip;

[0153] or,

[0154] The second connector is disposed on the protective sleeve, with one end connected to the antenna radiator and the other end connected to the second radio frequency chip of the electronic device through the satellite communication interface of the electronic device.

[0155] In this embodiment, the location of the first radio frequency chip on the protective case can be configured according to actual conditions. The first radio frequency chip can be located on the edge of the protective case or on the back panel of the protective case.

[0156] It should be noted that the protective case may include a first connector and a first radio frequency (RF) chip, meaning the protective case can independently control satellite communication. The protective case may also include a power supply module connected to the first RF chip to supply power. Alternatively, the protective case can be connected to the battery module of an electronic device, enabling the electronic device to power the first RF chip within the protective case.

[0157] For example, the first connector may be a cable, including coaxial cable, twisted pair cable, etc., and the embodiments disclosed herein are not limited thereto.

[0158] In this embodiment of the present disclosure, the protective cover may also be provided with a second connector, through which the second radio frequency chip of the electronic device can be connected to the antenna radiator, thereby enabling the electronic device to control the antenna radiator to operate in the satellite frequency band.

[0159] It should be noted that the satellite communication interface may include the communication interface of electronic devices (such as Lightning interface, Type-C interface, etc.), and the second connector may include cables or pogo pin connectors, etc.

[0160] It is understood that, in this embodiment of the present disclosure, a first radio frequency chip can be set on the protective case, and the first radio frequency chip and the antenna radiator can be connected through a first connector to enable the protective case to independently control satellite communication. Alternatively, in this embodiment of the present disclosure, the antenna radiator and the second radio frequency chip of the electronic device can be connected through a second connector, enabling the protective case to be used in conjunction with the electronic device, with the electronic device controlling the protective case for satellite communication. This makes the satellite communication method of the protective case more flexible and expands the applicable scenarios for the protective case.

[0161] This disclosure also provides an electronic device component. The electronic device component includes:

[0162] The protective sleeve as described in one or more of the above embodiments;

[0163] Electronic devices are fitted under the protective sleeve.

[0164] It is understood that the electronic device component includes a protective case, in which the antenna radiator and antenna coupling stub are spaced apart at the top edge of the protective case frame, and the antenna coupling stub can couple with the antenna radiator to work together in the satellite frequency band. Thus, the protective case of this embodiment can both protect the electronic device and enable satellite communication, achieving a dual function and enriching the functionality of the protective case.

[0165] Furthermore, in this embodiment, the antenna radiator and antenna coupling stub operating in the satellite frequency band are both located on the top edge of the protective case. This ensures that the antenna radiator and antenna coupling stub are not obstructed when the electronic device with the protective case is held in hand, thereby improving the antenna performance of the protective case operating in the satellite frequency band. Simultaneously, the antenna coupling stub and antenna radiator, after coupling, can work together in the satellite frequency band, thus increasing the radiation area and further improving the antenna performance of the protective case operating in the satellite frequency band.
