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.

[0038] Figure 1 This is a schematic diagram of an antenna accessory according to an exemplary embodiment. The antenna accessory includes a non-metallic substrate 1, a satellite antenna 2, and a satellite communication chip 3. The satellite antenna can be connected to the non-metallic substrate 1. The satellite antenna 2 may include a first antenna element 21 and a second antenna element 22 arranged side by side. The satellite communication chip 3 is disposed on the non-metallic substrate 1. The satellite communication chip 3 includes a feed terminal 31 and an electrical connection port 32. The feed terminal 31 is electrically connected to the first antenna element 21 and the second antenna element 22, thereby feeding electromagnetic wave signals to the satellite antenna through the satellite communication chip 3. The electrical connection port 32 can be used to electrically connect to the main body of the device, thereby realizing communication between the satellite communication chip 3 and the main body of the device. The first antenna element 21 and the second antenna element 22 can be constructed into a dipole satellite antenna. Utilizing the characteristic that the dipole antenna does not require grounding, the structure of the antenna accessory can be simplified. In other embodiments, the first antenna element 21 and the second antenna element 22 may also be arranged in other ways to obtain the satellite antenna 2.

[0039] In this embodiment, after assembling the antenna accessories with the main body of the device, the signal required to be transmitted by the main body of the device can be sent 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. The non-metallic substrate 1 may include a shell for enclosing the main body of the device, specifically, it may fully or partially enclose the main body. The first antenna element 21 and the second antenna element 22 are both located on the top of the non-metallic substrate 1. This ensures that when the antenna accessories are assembled to the main body of the device, the first antenna element 21 and the second antenna element 22 are both located on the top of the main body, which helps to ensure that the circular polarization pattern of the antenna is at the top, facilitating one-handed holding and satellite alignment using a conventional grip.

[0040] To communicate with the Tiantong satellite via satellite antenna 2, satellite antenna 2 needs to cover the TX 1.98GHz~2.01GHz and RX 2.17GHz~2.2GHz bands. Based on Figure 1The position of satellite antenna 2 was simulated, with the thickness direction of the non-metallic substrate 1 defined as the X-axis, the length direction as the Z-axis, and the width direction as the Y-axis, resulting in... Figure 2 and Figure 3 The left-hand circular polarization pattern of satellite antenna 2 shown is as follows: Figure 2 The left-hand circular polarization pattern of satellite antenna 2 is a two-dimensional view in the XOZ plane. Figure 3 This is a two-dimensional view of the left-hand circular polarization pattern of satellite antenna 2 in the YOZ plane. (See also...) Figure 2 and Figure 3 As shown, the left-hand circular polarization pattern of satellite antenna 2 has its end-fire direction pointing towards the zenith, allowing users to focus on the satellite using a conventional method of holding the device equipped with this antenna accessory with one hand, thus improving the user experience.

[0041] Furthermore, in order to increase the left-hand circularly polarized beamwidth of satellite antenna 2, such as Figure 4 As shown, the antenna accessory also includes a first scrambler plate 4 and a second scrambler plate 5, with the first antenna element 21 and the second antenna element 22 both located between the first scrambler plate 4 and the second scrambler plate 5. For example, as... Figure 2 As shown, the first antenna element 21 is adjacent to and spaced apart from the first micro-perturbation piece 4, and the second antenna element 22 is adjacent to and spaced apart from the second micro-perturbation piece 5. After the electrical signal is fed into the first antenna element 21 and the second antenna element 22 at the feed terminal 31, the coupling between the first antenna element 21 and the first micro-perturbation piece 4 can excite the first micro-perturbation piece 4 to resonate, and the coupling between the second antenna element 22 and the second micro-perturbation piece 5 can excite the second micro-perturbation piece 5 to resonate. The difference between the resonant frequency of the first micro-perturbation piece 4 and the resonant frequency of the second micro-perturbation piece 5 and the resonant frequency of the satellite antenna 2 is less than a set threshold, so as to improve the left-hand circularly polarized beamwidth of the satellite antenna 2. For example, the difference between the resonant frequency of the first micro-perturbation piece 4 and the resonant frequency of the second micro-perturbation piece 5 and the resonant frequency of the satellite antenna 2 can be less than or equal to 200MHz.

[0042] Furthermore, the first perturbation plate 4, the second perturbation plate 5, the first antenna element 21, and the second antenna element 22 are arranged symmetrically in pairs, which can improve the beamwidth enhancement effect of the left-hand circularly polarized satellite antenna 2. Of course, in some cases, the arrangement position of the satellite antenna 2 in the width direction of the non-metallic substrate 1 may be limited by the overall environment of the main body of the equipment to which the antenna accessory is matched. Therefore, the satellite antenna 2 may not be centered on the non-metallic substrate 1, thus making it impossible to achieve strict pairwise symmetry. Therefore, to a certain extent, the position and size of the first perturbation plate 4, the second perturbation plate 5, the first antenna element 21, and the second antenna element 22 can be finely adjusted according to the overall environment of the main body of the equipment.

[0043] In some examples, the width directions of the first antenna element 21, the second antenna element 22, the first micro-perturbation piece 4, and the second micro-perturbation piece 5 are parallel, and the length directions of the first antenna element 21, the second antenna element 22, the first micro-perturbation piece 4, and the second micro-perturbation piece 5 are parallel. Taking a non-metallic substrate 1 as an example, the length directions of the first antenna element 21, the second antenna element 22, the first micro-perturbation piece 4, and the second micro-perturbation piece 5 are all set along the width direction of the shell, and the width direction is all set along the thickness direction of the shell.

[0044] In the aforementioned embodiments, when the antenna components are assembled to the main body of the device, the distance between the first antenna element 21 and the second antenna element 22 and the camera protection ring of the main body of the device is greater than or equal to a set threshold in the length direction of the non-metallic substrate 1. This increases the effective area of ​​the satellite antenna 2 in the length direction of the non-metallic substrate 1. Moreover, by limiting the set threshold, the distance between the satellite antenna 2 and the conventionally protruding camera protection ring can be kept within a safe distance range to avoid contact and prevent the camera module structure from radiating to the satellite antenna 2.

[0045] Based on the technical solution disclosed herein, an electronic device is also provided. Figure 5 This is a side view of the electronic device. Figure 6 The diagram illustrates the positional relationship between a partial structure of the main body 101 of the electronic device and the satellite antenna 2 of the antenna accessories. In this electronic device, taking a non-metallic substrate 1 as an example, the non-metallic substrate 1 can completely enclose the main body 101, or partially enclose it; the specific design can be customized as needed. The first antenna element 21 and the second antenna element 22 are both located on the top of the main body 101. The main body 101 is electrically connected to the electrical connection port of the satellite communication chip 3, for example, via a USB interface or via pins; the specific design can be customized as needed. In other embodiments, the non-metallic substrate 1 can also be a bracket or clip structure.

[0046] The main body 101 of the device includes a frame 102, which includes a first antenna stub 105, a first slit 103, and a second slit 104. The first end of the first antenna stub 105 forms the first slit 103, and the second end forms the second slit 104. The first antenna stub 105, the first slit 103, and the second slit 104 are all located at the top of the frame 102. A first antenna element 21 and a second antenna element 22 are located between the first slit 103 and the second slit 104, and are also located at the top of the main body of the device. Therefore, when the satellite antenna 2 is working, not only can the satellite antenna 2 itself radiate signals outwards, such as... Figure 7As shown, it can also excite the first antenna stub 105 to generate a strong current, assist the satellite antenna in working, and improve the radiation performance of the satellite antenna 2.

[0047] The frame 102 may include at least one second antenna stub 106, which forms either a first gap 103 or a second gap 104. When the satellite antenna 2 is in communication mode, the radiation frequency bands covered by the first antenna stub 105 and the second antenna stub 106 are different from the radiation frequency band of the satellite antenna 2, reducing the mutual interference between the satellite antenna 2 and the first antenna stub 105 and the second antenna stub 106. For example, the frame 102 may include two second antenna stubs 106, one of which cooperates with the first antenna stub 105 to form the first gap 103, and the other second antenna stub 106 cooperates with the first antenna stub 105 to form the second gap 104. By providing multiple second antenna stubs 106, the coverage frequency band of the main body of the device can be extended.

[0048] To achieve frequency band adjustment of the first antenna stub 105 and the second antenna stub 106, the main body 101 of the device may further include at least one tuning circuit. Each tuning circuit is connected to any antenna stub or any second antenna stub, and the tuning circuit is used to switch the radiation frequency band of the antenna stub connected to it. For example, the tuning circuit includes one or more of resistive devices, capacitors, and inductors.

This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
