[0039] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings.

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.

[0041] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0042] Figure 1 This is a schematic diagram illustrating the structure of an antenna accessory according to an exemplary embodiment, such as... Figure 1 As shown, the antenna accessory includes a non-metallic substrate 1, a satellite antenna 2, and a satellite communication chip 3. The satellite antenna 2 is connected to the non-metallic substrate 1, is disposed on top of the non-metallic substrate 1, and is grounded. The satellite communication chip 3 is disposed on the non-metallic substrate 1, and includes a feed terminal 31 and an electrical connection port 32. The feed terminal 31 is electrically connected to the satellite antenna 2, thereby feeding electromagnetic wave signals to the satellite antenna 2 through the satellite communication chip 3. The electrical connection port 32 can be used for electrical connection with the main body of the device, thereby realizing communication between the satellite communication chip 3 and the main body of the device.

[0043] In this embodiment, after assembling the antenna accessories with the main body of the device, the signal required by the main body of the device can be transmitted to the target communication satellite through the electrical connection between the satellite communication chip 3, the satellite antenna 2, and the main body of the device. By placing the satellite antenna 2, used for communication with the target communication satellite, on the antenna accessories, space is freed up for other antennas on the main body of the device. This improves the frequency coverage of the main body of the device while meeting the communication needs between the main body and the target communication satellite through the antenna accessories. The non-metallic substrate 1 can be a shell, which can be used to wrap around the main body of the device. Specifically, it can fully or partially wrap the main body of the device. The satellite antenna 2 can be located on the top of the shell. Therefore, when the shell wraps around the main body of the device, the satellite antenna is located on top of the main body, which helps ensure that the circular polarization pattern of the antenna is located on top of the main body. This facilitates the user's one-handed grip on the main body and allows for satellite aiming using a conventional grip method, improving the user experience.

[0044] This satellite antenna may include an inverted-F satellite antenna. For example... Figure 1 and Figure 2 As shown, the antenna accessory also includes a first ground plane 4, the length direction of the satellite antenna 2 being arranged along the width direction of the non-metallic substrate 1, that is, as shown in the figure. Figure 1 As shown, the satellite antenna 2 is arranged horizontally along its length and the non-metallic substrate 1 along its width. The edge of the satellite antenna 2 is electrically connected to the first ground plane 4, and the feed terminal 31 is electrically connected to the middle of the satellite antenna 2, thus forming an inverted F structure antenna model.

[0045] In some embodiments, since the satellite antenna 2 is disposed on top of the non-metallic substrate 1, the width direction of the satellite antenna 2 can be parallel to the thickness direction of the non-metallic substrate 1. Therefore, the edge of the satellite antenna 2 parallel to the length direction can be relatively close to the inner surface of the non-metallic substrate 1 perpendicular to the thickness direction. Thus, the first floor 4 can be attached to the inner surface of the non-metallic substrate 1 perpendicular to the thickness direction. Based on the fact that the inner surface of the non-metallic substrate 1 is usually attached to the back plate of the device body, and therefore has a large area, the first floor 4 can be installed over a large area to achieve grounding. For example, Figure 3 As shown, the first floor 4 can be an annular first floor, thereby saving materials.

[0046] In the aforementioned example, the satellite antenna 2 is grounded by setting a first ground plane 4 on the surface of the non-metallic substrate 1 and by electrically connecting the first ground plane 4 to the satellite antenna 2. In other examples, such as... Figure 4As shown, the antenna accessory also includes a metal part 5 disposed on the non-metallic substrate 1. The metal part 5 is electrically connected to the satellite antenna 2, and the metal part 5 is located on the side of the satellite antenna 2 facing the interior of the non-metallic substrate 1. The metal part 5 can be used to be spaced apart from the frame of the grounding setting of the main body of the device, so that the metal part 5 can be equivalent to a capacitor returning to ground, realizing the grounding setting of the metal part 5. Moreover, compared with the above example which requires a large area of ​​the first floor 4 to achieve the grounding function, it is beneficial to reduce the laying area of ​​the first floor 4, save materials, and achieve a simple effect for the antenna accessory.

[0047] Based on the technical solution disclosed herein, such as Figure 5 An electronic device is also provided, comprising a device body 101 and an antenna accessory as described in any of the preceding examples; the device body 101 is electrically connected to the electrical connection port 32 of the satellite communication chip 3, for example, the device body 101 can be electrically connected to the electrical connection port 32 via a USB interface, or via pins; the satellite antenna 2 is located on the top of the device body 101, so that the gain pattern of the satellite antenna 2 faces the zenith, which is convenient for satellite aiming using a conventional one-handed grip, thus improving the user experience.

[0048] In some instances, the device body 101 may include a grounded frame 102 that is electrically connected to the satellite antenna 2, thereby grounding the satellite antenna 2, avoiding the need for a floor structure on the antenna accessories, and simplifying the structure of the antenna accessories.

[0049] In other instances, such as Figure 6 As shown, the antenna accessory includes a first ground plane 4 electrically connected to the satellite antenna 2. The first ground plane 4 is arranged in a ring structure, and in the thickness direction of the electronic device, the projection of the first ground plane 4 surrounds the projection of the camera module of the device body 101, which is beneficial for the first ground plane 4 to be grounded using the camera module.

[0050] Furthermore, the frame 102 may include a first antenna 103 and a second ground plane 104 that cooperates with the first antenna 103 to form an antenna clearance. In the thickness direction of the electronic device, the projection of the second ground plane 104 at least partially overlaps with the projection of the first ground plane 104. Based on this, ground sharing between the first antenna 103 and the satellite antenna 2 is achieved, which helps the first antenna 103 and the satellite antenna 2 to maintain their own modes and reduce mutual interference.

[0051] In some other examples, such as Figure 7As shown, the antenna accessory also includes a metal part 5 disposed on the non-metallic substrate 1. The metal part 5 is electrically connected to the satellite antenna 2, and the metal part 5 is located on the side of the satellite antenna 2 facing the interior of the non-metallic substrate 1. The frame 102 may include a first antenna 103, a second floor 104 that cooperates with the first antenna 103 to form an antenna clearance, and a grounding rib 105 connecting the first antenna 103 and the second floor 104. In the length direction of the electronic device, that is... Figure 7 In the vertical direction shown, the projection of the metal part 5 and the projection of the grounding rib position 105 at least partially overlap, and the gap between the metal part 5 and the grounding rib position 105 is less than or equal to a set threshold, so that the metal part 5 and the grounding rib position 105 can cooperate to form a capacitor. Through the coupling between the metal part 5 and the grounding rib position 105, the grounding setting of the metal part 5 is realized.

[0052] The overlapping area of ​​the projection of metal part 5 and the projection of the return rib position 105 is greater than or equal to 100 square millimeters to ensure the coupling effect between the two; in the length direction of the electronic device, the gap between metal part 5 and return rib position 105 is greater than 0 and less than or equal to 0.3 mm, that is... Figure 7 As shown, 0 < L ≤ 0.3 mm.

[0053] In the aforementioned example, the first antenna 103 can be positioned below the satellite antenna 2, and when the satellite antenna 2 is in communication mode, such as... Figure 8 As shown, a current can be excited on the first antenna 103, causing it to resonate and participate in the signal radiation of the satellite antenna 2, which is beneficial to improving the radiation performance of the satellite antenna 2. Optionally, the resonant frequency of the first antenna 103 after feed matching is before the resonant frequency of the target communication satellite. This feed matching is a matching circuit set between the feed end and the first antenna 103, and the resonant frequency can be adjusted to be after the resonant frequency of the target communication satellite through a tuning circuit. Taking the target communication satellite as a Tiantong satellite as an example, the resonant frequency of the Tiantong satellite is at 2.2GHz. Figure 9 As shown, Mark 1 is the resonant frequency after power matching, with a frequency of 1.788 GHz; Mark 2 is the resonant frequency after power matching and tuning circuitry, with a frequency of 2.44 GHz. (See also...) Figure 9 Curve S1 is the system efficiency curve of satellite antenna 2. It can be seen that after the resonant frequency is adjusted to 2.2GHz by the tuning circuit, the efficiency of the Tiantong band can be improved, which in turn helps to improve the efficiency of the satellite antenna.
