Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to an antenna assembly and an electronic device having the antenna assembly. Background Art

[0002] Currently, with the popularization of 5G communication technologies, people's communication experience is getting better and better. To meet different communication requirements, some electronic devices are equipped with satellite antennas to establish connections with satellites through the satellite antennas to achieve satellite communication. The structures of existing satellite antennas are relatively complex, and in order to improve the quality of satellite communication, the sizes of existing satellite antennas are relatively large, resulting in relatively large sizes of electronic devices equipped with satellite antennas and inconvenient portability. Summary of the Invention

[0003] This application provides an antenna assembly and an electronic device, which can implement satellite communication functions through a simple antenna structure and have a relatively small volume.

[0004] In a first aspect, an electronic device is provided. The electronic device includes a first antenna assembly. The first antenna assembly includes a circular metal part and a feed source. Among them, the circular metal part includes a feeding point and at least two grounding points. The at least two grounding points are used for grounding. The at least two grounding points include a first target grounding point and a second target grounding point that are located on both sides of the feeding point and are closest to the feeding point. The feed source is connected to the feeding point and is used to excite the circular metal part to generate a first excitation current that conducts along a first metal segment between the feeding point and the first target grounding point and a second excitation current that conducts along a second metal segment between the feeding point and the second target grounding point. The phase difference between the first excitation current and the second excitation current is 90°, so that the circular metal part forms a circularly polarized or elliptically polarized antenna, thereby supporting the reception and transmission of satellite communication signals.

[0005] In a second aspect, an antenna assembly is further provided. The antenna assembly includes a circular metal part and a feed source. Among them, the circular metal part includes a feeding point and at least two grounding points. The at least two grounding points are used for grounding. The at least two grounding points include a first target grounding point and a second target grounding point that are located on both sides of the feeding point and are closest to the feeding point. The feed source is connected to the feeding point and is used to excite the circular metal part to generate a first excitation current that conducts along a first metal segment between the feeding point and the first target grounding point and a second excitation current that conducts along a second metal segment between the feeding point and the second target grounding point. The phase difference between the first excitation current and the second excitation current is 90°, so that the circular metal part forms a circularly polarized or elliptically polarized antenna, thereby supporting the reception and transmission of satellite communication signals.

[0006] The antenna assembly and electronic device of the present application are configured by providing a feeding point and at least two grounding points on a ring-shaped metal piece. The at least two grounding points include a first target grounding point and a second target grounding point that are located on both sides of the feeding point and are the closest to the feeding point. When the feed source excites the ring-shaped metal piece through the feeding point, a first excitation current that conducts along a first metal segment between the feeding point and the first target grounding point and a second excitation current that conducts along a second metal segment between the feeding point and the second target grounding point can be excited. The phase difference between the first excitation current and the second excitation current is 90°, causing the ring-shaped metal piece to form a circularly polarized or elliptically polarized antenna, thereby supporting the reception and transmission of satellite communication signals. Thus, in the present application, by having the excitation current conduct along two parts between the feeding point and the grounding points on both sides, and with a 90° phase difference between the currents on the two parts, the ring-shaped metal piece can be made to form a circularly polarized or elliptically polarized antenna to support the reception and transmission of satellite communication signals. The structure is simple and the overall volume is small, achieving a relatively compact antenna structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] In the description of the embodiments of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "thickness", "width", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than implying or indicating that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In this application, the term "connection" mainly refers to a physical structural connection without other explanations. In the case of explanations, it may also include meanings such as electrical connection, direct connection or indirect connection. In the description of the embodiments of the present invention, terms such as "first" and "second" are not specific, but are used to distinguish objects with the same name. In the case of explanations in the specification, the objects with the same name referred to by terms such as "first" and "second" may be the same object.

[0039] Please refer to Figure 1 , which is a plan view of the electronic device 100 in some embodiments of the present application. As Figure 1 shown, the electronic device 100 includes a first antenna assembly 1. The first antenna assembly 1 includes a circular metal part 11 and a feed source 12. The circular metal part 11 includes a feeding point F1 and at least two grounding points G1. Among them, the at least two grounding points G1 are used for grounding. The at least two grounding points G1 include a first target grounding point G11 and a second target grounding point G12 that are located on both sides of the feeding point F1 and are the closest to the feeding point F1. The feed source 12 is connected to the feeding point F1 and is used to excite the circular metal part 11 to generate a first excitation current that conducts along a first metal segment 111 between the feeding point F1 and the first target grounding point G1, and a second excitation current that conducts along a second metal segment 112 between the feeding point F1 and the second target grounding point G12. The phase difference between the first excitation current and the second excitation current is 90°, so that the circular metal part 11 forms a circularly polarized or elliptically polarized antenna, thereby supporting the reception and transmission of satellite communication signals.

[0040] That is, in the present application, by providing a feeding point F1 and at least two grounding points G1 for grounding on the annular metal part 11, the at least two grounding points G1 include a first target grounding point G11 and a second target grounding point G12 that are located on both sides of the feeding point F1 and are the closest to the feeding point F1. When the feed source 12 excites the annular metal part 11 through the feeding point F1, a first excitation current that conducts along a first metal segment 111 between the feeding point F1 and the first target grounding point G11 and a second excitation current that conducts along a second metal segment 112 between the feeding point F1 and the second target grounding point G12 can be excited in the annular metal part 11. The phase difference between the first excitation current and the second excitation current is 90°, so that the annular metal part 11 forms a circularly polarized or elliptically polarized antenna, which supports the reception and transmission of satellite communication signals. Thus, in the present application, by exciting the current to conduct along two parts between the feeding point F1 and the grounding points G1 on both sides, and the phase difference of the current on the two parts is 90°, the annular metal part 11 can be made to form a circularly polarized or elliptically polarized antenna to support the reception and transmission of satellite communication signals. The structure is simple, and the overall volume is small, realizing a relatively compact antenna structure.

[0041] Among them, in the present application, the first target grounding point G11 and the second target grounding point G12 being located on both sides of the feeding point F1 and being the closest to the feeding point F1 means that the first target grounding point G11 and the second target grounding point G12 are respectively located on both sides of the feeding point F1, that is, the feeding point F1 is located between the first target grounding point G11 and the second target grounding point G12, and there are no other grounding points between the feeding point F1 and the first target grounding point G11, and there are also no other grounding points between the feeding point F1 and the second target grounding point G12.

[0042] Please refer to Figure 2 , which is a schematic diagram of the current distribution of the first antenna assembly 1 in some embodiments of the present application. It is a schematic diagram of the current distribution on the annular metal part 11 of the first antenna assembly 1 in some embodiments of the present application. As Figure 2 shown, when the feeding point F1 provided on the annular metal part 11 is connected to the feed source 12, a first excitation current i1 that conducts along a first metal segment 111 between the feeding point F1 and the first target grounding point G1 and a second excitation current i2 that conducts along a second metal segment 112 between the feeding point F1 and the second target grounding point G12 will be generated under the excitation of the feed source 12.

[0043] Among them, as Figure 2As shown, in some embodiments, the first excitation current i1 flows from the feeding point F1 to the first target grounding point G1, and the second excitation current i2 flows from the feeding point F2 to the second target grounding point G2.

[0044] In some embodiments, the difference between the equivalent electrical lengths of the first metal segment 111 between the feeding point F1 and the first target grounding point G1 and the second metal segment 112 between the feeding point F1 and the second target grounding point G12 is nλ / 2 + λ / 4, where λ is the wavelength corresponding to the frequency of the satellite communication signal, and n is 0 or a positive integer.

[0045] Among them, the first excitation current i1 and the second excitation current i2 are actually formed by the feeding signals generated by the feed 12 being fed into the annular metal part 11 and then conducting along the first metal segment 111 and the second metal segment 112 respectively. Therefore, at the feeding point F1, the initial phases of the first excitation current i1 and the second excitation current i2 are basically the same. And because the difference between the equivalent electrical lengths of the first metal segment 111 and the second metal segment 112 is nλ / 2 + λ / 4, therefore, as the first excitation current i1 and the second excitation current i2 conduct along the first metal segment 111 and the second metal segment 112 respectively, the phase of the first excitation current i1 when it reaches the first target grounding point G1 will differ by 90° from the phase of the second excitation current i2 when it reaches the second target grounding point G2.

[0046] Among them, in this application, the phase difference between the first excitation current and the second excitation current is 90°, specifically referring to the phase difference of 90° between the phase of the first excitation current i1 when it reaches the first target grounding point G1 and the phase of the second excitation current i2 when it reaches the second target grounding point G2.

[0047] Among them, since one period, that is, 360°, corresponds to the length of one wavelength, at the feeding point F1, the initial phases of the first excitation current i1 and the second excitation current i2 are basically the same. When the difference between the equivalent electrical lengths of the first metal segment 111 and the second metal segment 112 is nλ / 2 + λ / 4, it can correspondingly make the phase difference between the phase of the first excitation current i1 when it reaches the first target grounding point G1 and the phase of the second excitation current i2 when it reaches the second target grounding point G2 be n*360° ± 90°. Since a difference of 360° is a difference of 0 phase, it is thus ±90° (plus or minus 90°), that is, the phases of the first excitation current i1 and the second excitation current i2 will differ by 90°.

[0048] In some embodiments, since the annular metal part 11 is annular, for example, such asFigure 1 and Figure 2 the circular ring shape shown in Figure 2 . Therefore, the first metal segment 111 and the second metal segment 112 form a certain angle, and thus can be equivalently regarded as two substantially perpendicular radiation branches. For example, as shown in Figure 2 , Figure 2 the first metal segment 111 can be substantially equivalently regarded as a radiation branch Z1 connected between the feeding point F1 and the first target grounding point G11, and the second metal segment 112 can be substantially equivalently regarded as a radiation branch Z2 connected between the feeding point F1 and the second target grounding point G12. As can be seen from Figure 2 , Figure 2 the angle between the radiation branches Z1 and Z2 is close to 90°, which is substantially perpendicular. Therefore, when the phase difference between the first excitation current i1 in the first metal segment 111 and the second excitation current i2 in the second metal segment 112 is 90°, and the first metal segment 111 and the second metal segment 112 are equivalently regarded as two substantially perpendicular radiation branches Z1 and Z2, thus satisfying the conditions of circular polarization or elliptical polarization and being able to support the reception and transmission of satellite communication signals. Among them, Figure 2 in Figure 2 , the radiation branch Z1 equivalently regarded as the first metal segment 111 and the radiation branch Z2 equivalently regarded as the second metal segment 112 are schematically shown by dashed lines.

[0049] Among them, in some embodiments, the equivalent electrical length of the first metal segment 111 may be the equivalent electrical length of the first metal segment 111 itself. For example, it may be substantially equal to the length of the first metal segment 111. In some embodiments, when the first metal segment 111 is further connected with a matching unit for realizing matching adjustment, the equivalent electrical length of the first metal segment 111 may also be the equivalent electrical length equivalent under the cooperation of the connected matching unit. Similarly, in some embodiments, the equivalent electrical length of the second metal segment 112 may be the equivalent electrical length of the second metal segment 112 itself. For example, it may be substantially equal to the length of the second metal segment 112. In some embodiments, when the second metal segment 112 is further connected with a matching unit for realizing matching adjustment, the equivalent electrical length of the second metal segment 112 may also be the equivalent electrical length equivalent under the cooperation of the connected matching unit.

[0050] Please refer to Figure 3 , which is a further structural schematic diagram of the first antenna assembly 1 included in the electronic device 100 in some embodiments of the present application. Among them, in some embodiments, as shown in Figure 3 , Figure 3As shown, the first target ground point G11 and the second target ground point G12 divide the annular metal part 11 into a feeding part P1 including the feeding point F1 and a non-feeding part P2 not including the feeding point F1. The at least two ground points G1 further include at least one third target ground point G13, and the at least one third target ground point G13 is located in the non-feeding part P2 of the annular metal part 11.

[0051] That is, compared with Figure 1 the first antenna assembly 1 included in the electronic device 100 shown, in some embodiments, such as Figure 3 As shown, the at least two ground points G1 further include at least one third target ground point G13, and the at least one third target ground point G13 is located in the non-feeding part P2 of the annular metal part 11.

[0052] That is, compared with Figure 1 the first antenna assembly 1 included in the electronic device 100 shown, in some embodiments, such as Figure 3 As shown, the at least two ground points G1 further include at least one third target ground point G13, and the at least one third target ground point G13 is located in the non-feeding part P2 of the annular metal part 11.

[0053] Among them, as Figure 3 shown, the first target ground point G11 and the second target ground point G12 divide the annular metal part 11 into a feeding part P1 and a non-feeding part P2. The feeding part P1 is the part including the feeding point F1, and the non-feeding part P2 is the part not including the feeding point F1. The first target ground point G11 and the second target ground point G12 are equivalent to the demarcation points of the two parts of the feeding part P1 and the non-feeding part P2. In the non-feeding part P2, other ground points G1 may further be included, that is, at least one third target ground point G13 is further included.

[0054] Among them, the feeding part P1 includes the first metal segment 111 between the feeding point F1 and the first target ground point G1 and the second metal segment 112 between the feeding point F1 and the second target ground point G12 described above.

[0055] Among them, in some embodiments, since the current generated by the feed source 12 exciting the annular metal part 11 is mainly distributed in the first metal section 111 between the feeding point F1 and the first target grounding point G11 and the second metal section 112 between the feeding point F1 and the second target grounding point G12, that is, distributed on the feeding part P1, mainly the feeding part P1 participates in the radiation of the satellite communication signal. Among them, the aforementioned feed source 12 excites the annular metal part 11 to form a circularly polarized or elliptically polarized antenna, which supports the reception and transmission of satellite communication signals. It can also refer to the feeding part P1 supporting the reception and transmission of satellite communication signals under the excitation of the feed source 12.

[0056] Among them, when there is no other grounding point G1 in the non-feeding part P2, it may couple and resonate with the ground to generate clutter. Therefore, other grounding points G1 can be set on the non-feeding part P2, so as to break the coupling resonance condition, and avoid or reduce the clutter generated by the coupling resonance between the non-feeding part P2 and the ground, and avoid or reduce the interference to the satellite communication signal.

[0057] Among them, as Figure 3 shown, the number of the third target grounding points G13 is two. Obviously, in some embodiments, the number of the third target grounding points G13 can be one, three, four or other numbers. When any number of other grounding points G1, that is, the third target grounding points G13, are grounded on the non-feeding part P2, the coupling resonance condition between the non-feeding part P2 and the ground can be broken, and the clutter generated by the coupling resonance between the non-feeding part P2 and the ground can be avoided or reduced, and the interference to the satellite communication signal can be avoided or reduced.

[0058] Please refer to Figure 4 , which is another structural schematic diagram of the first antenna assembly 1 in some embodiments of the present application. In some embodiments, as Figure 4 shown, the third target grounding points G13 are arranged in all areas of the non-feeding part P2, and the non-feeding part P2 is all grounded. Among them, Figure 4 in, the non-feeding part P2 is all black, representing that the whole non-feeding part P2 is grounded.

[0059] That is, in some embodiments, all areas in the non-feeding part P2 are grounded, that is, it is regarded that the third target grounding points G13 are arranged in all areas of the non-feeding part P2.

[0060] Thus, in some embodiments, grounding the entire non-feed portion P2 can more effectively disrupt the coupled resonance condition between the non-feed portion P2 and the ground, ensuring the avoidance of clutter generated by the coupled resonance between the non-feed portion P2 and the ground, and thus avoiding interference with the satellite communication signal.

[0061] Among them, the reason for the occurrence of coupled resonance between the non-feed portion P2 and the ground is that the size of the non-feed portion P2 may meet the coupled resonance condition. For example, the size of the non-feed portion P2 may be relatively close to the size required for the resonance frequency of the fundamental mode or higher harmonics of the satellite communication signal, and thus coupled resonance can occur. Therefore, in some embodiments, when the size of the non-feed portion P2 does not meet the coupled resonance condition, no grounding point G1 needs to be provided for the non-feed portion P2.

[0062] Among them, in this application, the position of the feeding point F1 on the annular metal part 11 is not limited. That is, it can be at any position on the annular metal part 11, as long as the feeding point F1 is located between the first target grounding point G1 and the second target grounding point G12, and the difference between the equivalent electrical length of the first metal segment 111 between the feeding point F1 and the first target grounding point G1 and the equivalent electrical length of the second metal segment 112 between the feeding point F1 and the second target grounding point G12 is nλ / 2 + λ / 4.

[0063] For example, as Figure 1 and Figures 3 - 4 shown, the feeding point F1 is generally located slightly to the left above the perspective shown in Figure 1 and Figures 3 - 4 of the annular metal part 11.

[0064] Among them, in some embodiments, the beam direction of the first antenna assembly 1 is biased towards the non-feed portion P2. Thus, in some embodiments, the positions of the first target ground point G1 and the second target ground point G12 can be set according to the desired beam direction of the first antenna assembly 1, so that the non-feed portion P2 is located at a corresponding position on the annular metal member 11. Therefore, in some embodiments, when there is a further requirement for the beam direction, it can be ensured that the feed point F1 is located between the first target ground point G1 and the second target ground point G12, and the difference in the equivalent electrical length between the first metal segment 111 between the feed point F1 and the first target ground point G1 and the second metal segment 112 between the feed point F1 and the second target ground point G12 is nλ / 2 + λ / 4. Further, the positions of the first target ground point G11 and the second target ground point G12 can be selected, and the non-feed portion P2 excluding the feed point F1 can be limited to a corresponding position, so that the beam direction can be biased towards the non-feed portion P2, and a certain degree of adjustment of the beam direction can be achieved according to needs.

[0065] Among them, the beam direction of the first antenna assembly 1 is the main radiation direction of the first antenna assembly 1.

[0066] Among them, as Figure 1 shown, the electronic device 100 includes a top end D1, a bottom end D2, a first side end D3, and a second side end D4. Among them, in some embodiments, when the annular metal member 11 is located in the electronic device 100, the upper, lower, left, and right sides of the annular metal member 11 are respectively positions facing the top end D1, the bottom end D2, the first side end D3, and the second side end D4 of the electronic device 100.

[0067] In some embodiments, the bottom end D2 of the electronic device 100 is the end provided with a headphone jack and a USB jack, and the top end D1 of the electronic device 100 is the other end opposite to the end provided with the headphone jack and the USB jack. For example, the top end D1 of the electronic device 100 is the end provided with a camera.

[0068] As Figure 1 shown, the position slightly to the left above the annular metal member 11 is the position where the annular metal member 11 faces the top end D1 of the electronic device 100 and is slightly biased towards the first side end D3 when the annular metal member 11 is located in the electronic device 100. Therefore, in terms of the position of the annular metal member 11 in the electronic device 100, in some embodiments, as Figure 1As shown, the feeding point F1 is generally located at the position of the annular metal part 11 facing the top end D1, and specifically at the position of the annular metal part 11 near the top end D1 of the electronic device and slightly biased towards the first side end D3.

[0069] Among them, the aforementioned Figure 3 The positions of the feeding point F1, the first target grounding point G11, and the second target grounding point G12 in the annular metal part 11 shown can be the same as those of the feeding point F1, the first target grounding point G11, and the second target grounding point G12 in the annular metal part 11 shown in Figure 1 Only that Figure 3 The annular metal part 11 shown further includes a third target grounding point G13.

[0070] Please refer to Figure 5 , which is another structural schematic diagram of the first antenna assembly 1 of the electronic device 100 in some embodiments of the present application.

[0071] Among them, as Figure 5 shown, in some embodiments, the feeding point F1 is generally located at the lower right position of the annular metal part 11 in the Figure 5 view shown.

[0072] Among them, as described above, the upper, lower, left, and right sides of the annular metal part 11 are respectively the positions facing the top end D1, the bottom end D2, the first side end D3, and the second side end D4 of the electronic device 100. Therefore, the lower right position of the annular metal part 11 is the position of the annular metal part 11 facing the bottom end D2 and the second side end D4 of the electronic device 100 when the annular metal part 11 is located in the electronic device 100. Therefore, in terms of the position of the annular metal part 11 in the electronic device 100, the feeding point F1 is generally located at the position of the annular metal part 11 facing the bottom end D2 and the second side end D4 of the electronic device 100.

[0073] That is, in some embodiments, the feeding point F1 can also be set at the position of the annular metal part 11 generally facing the bottom end D2 and the second side end D4 of the electronic device 100. When the difference between the equivalent electrical lengths of the first metal segment 111 between the feeding point F1 and the first target grounding point G1 and the second metal segment 112 between the feeding point F1 and the second target grounding point G12 is nλ / 2 + λ / 4, it can still exhibit circular polarization or elliptical polarization characteristics under the excitation of the feed source 12, that is, the annular metal part 11 can still form a circular polarization or elliptical polarization antenna and can support the transceiver of satellite communication signals.

[0074] Among them,Figure 5 Among them, taking the example that the annular metal member 11 includes a third target ground point G13 is schematically shown.

[0075] Please refer to Figure 6 , which is another schematic structural diagram of the first antenna assembly 1 of the electronic device 100 in some embodiments of the present application.

[0076] Among them, as Figure 6 shown, in some embodiments, the feeding point F1 is generally located at the upper right position in the perspective shown of the annular metal member 11. Figure 6 shown in the perspective.

[0077] Among them, as described above, the upper, lower, left, and right sides of the annular metal member 11 are respectively the positions facing the top end D1, bottom end D2, first side end D3, and second side end D4 of the electronic device 100. Therefore, the upper right position of the annular metal member 11 is the position where the annular metal member 11 faces the top end D1 and the second side end D4 of the electronic device 100 when the annular metal member 11 is located in the electronic device 100. Therefore, in terms of the position of the annular metal member 11 in the electronic device 100, the feeding point F1 can also be generally located at the position where the annular metal member 11 faces the top end D1 and the second side end D4 of the electronic device 100.

[0078] Thus, in some embodiments, the feeding point F1 can also be set at the position where the annular metal member 11 generally faces the bottom end D2 and the second side end D4 of the electronic device 100. When the difference between the equivalent electrical length of the first metal segment 111 between the feeding point F1 and the first target ground point G1 and the equivalent electrical length of the second metal segment 112 between the feeding point F1 and the second target ground point G12 is nλ / 2 + λ / 4, it can still exhibit circular polarization or elliptical polarization characteristics under the excitation of the feed source 12, that is, the annular metal member 11 can still form a circular polarization or elliptical polarization antenna, and can support the transceiver of satellite communication signals.

[0079] Among them, Figure 6 among them, taking the example that the annular metal member 11 includes a third target ground point G13 is also schematically shown.

[0080] Please refer to Figure 7 , which is yet another schematic structural diagram of the first antenna assembly 1 of the electronic device 100 in some embodiments of the present application.

[0081] Among them, as Figure 7 shown, in some embodiments, the feeding point F1 is generally located at the lower left position in the perspective shown of the annular metal member 11. Figure 7 shown in the perspective.

[0082] Among them, as described above, above, below, to the left, and to the right of the annular metal part 11 are the positions facing the top end D1, bottom end D2, first side end D3, and second side end D4 of the electronic device 100 respectively. Therefore, the lower left position of the annular metal part 11 is the position where the annular metal part 11 faces the bottom end D2 and the first side end D3 of the electronic device 100 when the annular metal part 11 is located in the electronic device 100. Therefore, in terms of the position of the annular metal part 11 in the electronic device 100, the feeding point F1 can also be approximately located at the position where the annular metal part 11 faces the bottom end D2 and the first side end D3 of the electronic device 100.

[0083] Among them, Figure 7 In the figure, an example is also schematically shown in which the annular metal part 11 includes a third target grounding point G13.

[0084] Please refer to Figure 8 , which is a schematic diagram of other structures of the first antenna assembly 1 of the electronic device 100 in some embodiments of the present application.

[0085] Among them, as Figure 8 shown, in some embodiments, the feeding point F1 is approximately located at the upper left position of the annular metal part 11 in the Figure 8 view shown.

[0086] Among them, as described above, above, below, to the left, and to the right of the annular metal part 11 are the positions facing the top end D1, bottom end D2, first side end D3, and second side end D4 of the electronic device 100 respectively. Therefore, the upper left position of the annular metal part 11 is the position where the annular metal part 11 faces the top end D1 and the first side end D3 of the electronic device 100 when the annular metal part 11 is located in the electronic device 100. Therefore, in terms of the position of the annular metal part 11 in the electronic device 100, the feeding point F1 can also be approximately located at the position where the annular metal part 11 faces the top end D1 and the first side end D3 of the electronic device 100.

[0087] Among them, Figure 8 In the figure, an example is given in which the annular metal part 11 does not include the third target grounding point G13. That is, the annular metal part 11 only includes the first target grounding point G11 and the second target grounding point G12, and does not include the grounding point G1 in the non-feeding part P2. As described above, in some embodiments, when the size of the non-feeding part P2 does not meet the coupling resonance condition, no grounding point G1 may be provided in the non-feeding part P2. Therefore, as Figure 8 and the foregoing Figure 1As shown, the annular metal part 11 may only include the first target ground point G11 and the second target ground point G12, and does not include the ground point G1 located in the non-feeding part P2, that is, does not include the third target ground point G13.

[0088] Wherein, as described above, in some embodiments, the difference between the equivalent electrical length of the first metal segment 111 between the feeding point F1 and the first target ground point G11 and the equivalent electrical length of the second metal segment 112 between the feeding point F1 and the second target ground point G12 is nλ / 2 + λ / 4, where λ is the wavelength corresponding to the frequency of the satellite communication signal, and n is 0 or a positive integer. And the equivalent electrical length of the first metal segment 111 may be the equivalent electrical length of the first metal segment 111 itself, or when a matching unit is connected, it is the equivalent electrical length equivalent with the cooperation of the connected matching unit, and the equivalent electrical length of the second metal segment 112 may be the equivalent electrical length of the second metal segment 112 itself, or when a matching unit is connected, it is the equivalent electrical length equivalent with the cooperation of the connected matching unit.

[0089] Please refer to Figure 9 , which is another schematic structural diagram of the first antenna assembly 1 of the electronic device 100 in some embodiments of the present application.

[0090] Wherein, in some embodiments, as Figure 9 shown, the first antenna assembly 1 further includes at least one matching unit M1, and at least one of the first target ground point G11 and the second target ground point G12 is grounded through the matching unit M1. Wherein, when the first target ground point G11 is grounded through the matching unit M1, the equivalent electrical length of the first metal segment 111 is the equivalent electrical length with the cooperation of the matching unit M1, and when the second target ground point G12 is grounded through the matching unit M1, the equivalent electrical length of the second metal segment 112 is the equivalent electrical length with the cooperation of the matching unit M1.

[0091] Thus, in some embodiments, at least one of the first target ground point G11 and the second target ground point G12 is grounded through the matching unit M1, so that the sizes of the first metal segment 111 and / or the second metal segment 112 can be designed more flexibly, without the need for their own equivalent electrical lengths to be fixed at the required equivalent electrical lengths, and it is only necessary that the equivalent electrical lengths under the cooperation of the matching unit M1 meet the requirements. For example, when both the first target ground point G11 and the second target ground point G12 are grounded through the matching unit M1, the difference between the equivalent electrical length of the first metal segment 111 under the cooperation of the corresponding matching unit M1 and the equivalent electrical length of the second metal segment 112 under the cooperation of the matching unit M1 is nλ / 2 + λ / 4.

[0092] Wherein, the matching unit M1 may include an inductor and / or a capacitor.

[0093] Wherein, as Figure 9 shown, in some embodiments, taking the first target ground point G11 directly grounded, the second target ground point G12 grounded through the matching unit M1, and the matching unit M1 including a capacitor C1 as an example for illustration.

[0094] In some embodiments, it may also be that the first target ground point G11 is grounded through the matching unit M1, while the second target ground point G12 is directly grounded, or both the first target ground point G11 and the second target ground point G12 are grounded through the corresponding matching unit M1.

[0095] In some embodiments, the matching unit M1 may include multiple capacitors and / or multiple inductors. For example, it may also include multiple capacitors connected in series or in parallel, or multiple inductors connected in series or in parallel, or include a series of capacitors and inductors, or parallel capacitors and inductors. Wherein, when both the first target ground point G11 and the second target ground point G12 pass through the corresponding matching unit M1, the structures of the matching unit M1 respectively connected to the first target ground point G11 and the second target ground point G12 may be the same or different. For example, the matching unit M1 connected to the first target ground point G11 may include an inductor, while the matching unit M1 connected to the second target ground point G12 includes a capacitor.

[0096] Please refer to Figure 10 , which is another schematic structural diagram of the first antenna assembly 1 of the electronic device 100 in some embodiments of the present application.

[0097] As Figure 10As shown, in some embodiments, the first antenna assembly 1 further includes a metal sheet 13 disposed within the space R1 surrounded by the annular metal member 11. The side edge of the metal sheet 13 is at least adjacent to a 1 / 4 perimeter portion of the annular metal member 11 that includes the feeding point F1, and the metal sheet 13 is coupled to the annular metal member 11.

[0098] Among them, the side edge of the metal sheet 13 being at least adjacent to a 1 / 4 perimeter portion of the annular metal member 11 that includes the feeding point F1 may mean that when the metal sheet 13 and the annular metal member 11 are projected onto the same plane, for example, when projected onto the plane where the metal sheet 13 is located, the projection of the side edge of the metal sheet 13 is directly opposite or partially overlaps with the projection of a 1 / 4 perimeter portion of the annular metal member 11 that includes the feeding point F1.

[0099] In some embodiments, the surface of the metal sheet 13 is parallel to the plane where the annular metal member 11 is located. Among them, the metal sheet 13 is generally plate-shaped or sheet-shaped, the surface of the metal sheet 13 refers to the surface with the largest area of the metal sheet 13, and the plane where the annular metal member 11 is located refers to the plane parallel to the circumferential direction of the annular metal member 11.

[0100] Among them, a 1 / 4 perimeter portion of the annular metal member 11 that includes the feeding point F1 may refer to the portions corresponding to the four quadrants divided by taking the up-down direction and the left-right direction of the annular metal member 11 as the quadrant axes. For example, as Figure 10 shown, the annular metal member 11 may include four quadrants, and through the four quadrants, four 1 / 4 perimeter portions are defined, namely, the 1 / 4 perimeter portion B11 corresponding to the upper right first quadrant, the 1 / 4 perimeter portion B12 corresponding to the upper left second quadrant, the 1 / 4 perimeter portion B13 corresponding to the lower left third quadrant, and the 1 / 4 perimeter portion B14 corresponding to the lower right fourth quadrant.

[0101] Among them, as described above, when the annular metal member 11 is located in the electronic device 100, the upper, lower, left, and right sides of the annular metal member 11 are respectively positions facing the top end D1, bottom end D2, first side end D3, and second side end D4 of the electronic device 100. Therefore, the 1 / 4 perimeter portion B11 corresponding to the upper right first quadrant is a portion generally facing the top end D1 and the second side end D4 of the electronic device 100, the 1 / 4 perimeter portion B12 corresponding to the upper left second quadrant is a portion generally facing the top end D1 and the first side end D3 of the electronic device 100, the 1 / 4 perimeter portion B13 corresponding to the lower left third quadrant is a portion generally facing the bottom end D2 and the first side end D3 of the electronic device 100, and the 1 / 4 perimeter portion B14 corresponding to the lower right fourth quadrant is a portion generally facing the bottom end D2 and the second side end D4 of the electronic device 100.

[0102] In some embodiments, since the two ends of the 1 / 4 perimeter portion where the feeding point F1 is located exactly differ by a quarter of the perimeter, that is, the corresponding radian is π / 4, namely 90°, the currents in the tangential directions of the two ends of the 1 / 4 perimeter portion where the feeding point F1 is located will be perpendicular to each other, which is beneficial to realizing the circular polarization or elliptical polarization characteristics and forming a circular polarization or elliptical polarization antenna.

[0103] Therefore, by further providing the metal sheet 13, and the side edge of the metal sheet 13 is at least adjacent to the 1 / 4 perimeter portion of the annular metal member 11 including the feeding point F1, and the metal sheet 13 is coupled to the annular metal member 11, corresponding currents can be coupled out on the edge of the metal sheet 13, and there will also be at least two mutually perpendicular tangential currents in the currents coupled out on the metal sheet 13, which can effectively improve the radiation performance.

[0104] In some embodiments, there may be a gap and the metal sheet 13 is close to the annular metal member 11, so as to be coupled to the annular metal member 11. Among them, an insulating material may be filled between the metal sheet 13 and the annular metal member 11. For example, the metal sheet 13 can be fixed on the inner circumference of the annular metal member 11 by filling insulating glue. In some embodiments, the metal sheet 13 can also be fixed on the component of the electronic device 100 surrounded by the annular metal member 11, and there is a gap and is close to the annular metal member 11, so as to be coupled to the annular metal member 11.

[0105] Among them, as described above, taking the four directions above, below, left, and right of the annular metal part 11 as the quadrant axes, four quadrants are divided. The space R1 surrounded by the annular metal part 11 actually also includes the spaces located in these four quadrants respectively. In some embodiments, at least the side edge of the metal sheet 13 is adjacent to the 1 / 4 perimeter part of the annular metal part 11 including the feeding point F1, which may also mean that the metal sheet 13 is at least located in the quadrant where the feeding point F1 is located.

[0106] Among them, as Figure 10 shown, in some embodiments, the feeding point F1 may be located in the upper right of the annular metal part 11, that is, the feeding point F1 is set at a certain position in the 1 / 4 perimeter part B11 corresponding to the first quadrant in the upper right. The side edge of the metal sheet 13 is adjacent to the 1 / 4 perimeter part of the annular metal part 11 including the feeding point F1 and is also adjacent to another 1 / 4 perimeter part. In some embodiments, as Figure 10 shown, the metal sheet 13 is generally arranged in the right half part of the space R1 surrounded by the annular metal part 11. The side edge of the metal sheet 13 is adjacent to the 1 / 4 perimeter part B11 corresponding to the first quadrant in the upper right and the 1 / 4 perimeter part B14 corresponding to the fourth quadrant in the lower right.

[0107] That is, in some embodiments, the metal sheet 13 may be located in the first quadrant and the second quadrant parts of the space R1. Therefore, the side edge of the metal sheet 13 is adjacent to the 1 / 4 perimeter part B11 corresponding to the first quadrant in the upper right and the 1 / 4 perimeter part B14 corresponding to the fourth quadrant in the lower right.

[0108] Among them, as Figure 10 shown, the annular metal part 11 may not include the third target grounding point G13 because the metal sheet 13 can to a certain extent damage the coupling between the non-feeding part P2 and the ground. Therefore, the third target grounding point G13 may not be set on the non-feeding part P2 for grounding. Of course, in some embodiments, when the metal sheet 13 is included, the third target grounding point G13 may also be set on the non-feeding part P2 for grounding to ensure avoiding the generation of clutter.

[0109] Please refer to Figure 11 , which is another schematic structural diagram of the first antenna assembly 1 of the electronic device 100 in some embodiments of the present application.

[0110] Among them, as Figure 11As shown, the metal sheet 13 can be disposed within the entire space R1 formed by surrounding of the annular metal member 11, that is, the side edges of the metal sheet 13 can be adjacent to the entire inner circumference of the annular metal member 11. Among them, the outer circumference of the metal sheet 13 and the inner circumference of the annular metal member 11 can be substantially the same in shape and spaced apart from each other.

[0111] In some embodiments, when the metal sheet 13 is disposed within the entire space R1 formed by surrounding of the annular metal member 11, at least one functional hole K1 can be formed in the metal sheet 13, and the functional hole K1 can correspond to a functional component of the electronic device 100, so that the metal sheet 13 does not obstruct the corresponding function of the functional component K1.

[0112] Obviously, as described above, the side edges of the metal sheet 13 are at least adjacent to the 1 / 4 circumference portion of the annular metal member 11 including the feeding point F1. Therefore, the metal sheet 13 can also be disposed only in the portion of the space R1 formed by surrounding of the annular metal member 11 that is adjacent to the 1 / 4 circumference portion including the feeding point F1. For example, when the feeding point F1 is disposed at the upper right position of the annular metal member 11, the metal sheet 13 can also be disposed only in the upper right portion of the space R1 formed by surrounding of the annular metal member 11. When the feeding point F1 is disposed at the lower right position of the annular metal member 11, the metal sheet 13 can also be disposed only in the lower right portion of the space R1 formed by surrounding of the annular metal member 11.

[0113] In some embodiments, the metal sheet 13 can also be disposed in three quadrant portions of the space R1, and a feeding point F1 is disposed in the 1 / 4 circumference portion of the metal sheet 13 corresponding to one of the quadrant portions. For example, when the feeding point F1 can be located at the upper right of the annular metal member 11, that is, the feeding point F1 is disposed at a certain position in the 1 / 4 circumference portion B11 corresponding to the first quadrant at the upper right, the metal sheet 13 can be disposed in the first quadrant portion, the second quadrant portion, and the third quadrant portion of the space R1, or disposed in the first quadrant portion, the second quadrant portion, and the fourth quadrant portion of the space R1.

[0114] That is, as long as the side edges of the metal sheet 13 are at least adjacent to the 1 / 4 circumference portion of the annular metal member 11 including the feeding point F1, the setting position, shape, area size, etc. of the metal sheet 13 are not limited.

[0115] Among them, in some embodiments, no matter where the metal sheet 13 is disposed, when the metal sheet 13 blocks the functional component of the electronic device 100, a functional hole or notch can be formed at the corresponding position to avoid obstructing the corresponding function of the functional component.

[0116] Among them, as Figures 1 - 11 shown in the figures such as, in some embodiments, the number of the feeding points F1 is one, and the nearest first target grounding point G11 and the second target grounding point G12 to the feeding point F1 are each one.

[0117] Thus, in some embodiments, the feeding point F1 is connected to the feed source 12, and the first excitation current conducted along the first metal segment 111 between the feeding point F1 and the first target grounding point G1 and the second excitation current conducted along the second metal segment 112 between the feeding point F1 and the second target grounding point G12 are generated in the annular metal part 11 under the excitation of the feed source 12. And since the difference between the equivalent electrical length of the first metal segment 111 between the feeding point F1 and the first target grounding point G11 and the equivalent electrical length of the second metal segment 112 between the feeding point F1 and the second target grounding point G12 is nλ / 2 + λ / 4, therefore, the phase difference between the first excitation current and the second excitation current can be made 90°, so that the annular metal part 11 exhibits circular polarization or elliptical polarization characteristics to form a circular polarization or elliptical polarization antenna, and can support the transceiver of satellite communication signals.

[0118] Please refer to Figure 12 , which is a schematic structural diagram of the first antenna assembly 1 of the electronic device 100 in some other embodiments of the present application.

[0119] Among them, in some other embodiments, the feeding point F1 may include multiple ones. For example, as Figure 12As shown, the feeding point F1 includes a first feeding point F11 and a second feeding point F12. There are two of the first target grounding points G11 and two of the second target grounding points G12. One of the first target grounding points G11 and one of the second target grounding points G12 are located on both sides of the first feeding point F11 and are the closest to the first feeding point F11 on their respective sides. The other first target grounding point G11 and the other second target grounding point G12 are located on both sides of the second feeding point F12 and are the closest to the second feeding point F12 on their respective sides. Among them, the first target grounding points G11 and the second target grounding points G12 located on both sides of the first feeding point F11 divide the annular metal part 11 into a first feeding part P11 including the first feeding point F1 and a first non-feeding part P21 not including the first feeding point F11. The first target grounding points G11 and the second target grounding points G12 located on both sides of the second feeding point F12 divide the annular metal part 11 into a second feeding part P12 including the second feeding point F12 and a second non-feeding part P22 not including the second feeding point F12. Among them, the aforementioned feeding part 111 includes the first feeding part P11 and the second feeding part P12, and the aforementioned non-feeding part P2 is the overlapping part of the first non-feeding part P21 and the second non-feeding part P22.

[0120] That is, in some other embodiments, the feeding point F1 may include multiple ones, and on both sides of each feeding point F1, there is a first target grounding point G11 and a second target grounding point G12 that are the closest to the feeding point F1. Each feeding point F1 is connected to a corresponding feeding source. The annular metal part 11 generates a first excitation current conducted along a first metal segment between the feeding point F1 and the first target grounding point G11 and a second excitation current conducted along a second metal segment between the feeding point F1 and the second target grounding point G12 under the excitation of the corresponding feeding source. The phase difference between the first excitation current and the second excitation current is 90°, so as to support the transceiver of satellite communication signals.

[0121] Among them, since the excitation current mainly conducts between a first metal segment 111 between each feeding point F1 and the corresponding first target grounding point G11 and a second metal segment 112 between the feeding point F1 and the corresponding second target grounding point G12, and the first metal segment 111 and the second metal segment 112 are the aforementioned feeding parts, actually only the feeding part P1 plays a radiation role. For example, as Figure 12As shown, when the feeding point F includes a first feeding point F11 and a second feeding point F12, the first target grounding points G11 and the second target grounding points G12 on both sides of the first feeding point F11 divide the annular metal part 11 into a first feeding part P11 including the first feeding point F11 and a first non-feeding part P21 not including the first feeding point F11. The first feeding part P11 supports the transceiver of satellite communication signals under the excitation of the corresponding feeding source. Similarly, the first target grounding points G11 and the second target grounding points G12 on both sides of the second feeding point F12 divide the annular metal part 11 into a second feeding part P12 including the second feeding point F12 and a second non-feeding part P22 not including the second feeding point F12. The second feeding part P12 supports the transceiver of satellite communication signals under the excitation of the corresponding feeding source.

[0122] In some embodiments, the feeding sources connected to each feeding point F1 may be the same. That is, the first feeding point F11 and the second feeding point F12 may both be connected to the aforementioned feeding source 12. Thus, the satellite communication signals supported by the first feeding part P11 for transceiver under the excitation of the feeding source 12 may be the same as the satellite communication signals supported by the second feeding part P12 for transceiver under the excitation of the feeding source 12. For example, they are all Beidou satellite communication signals of the same frequency band. Thus, the first antenna assembly 1 may include at least two antenna structures capable of supporting the transceiver of satellite communication signals of the same frequency band, effectively improving the satellite communication performance.

[0123] Obviously, in some other embodiments, the feeding sources connected to each feeding point F1 may be different. For example, the first feeding point F11 may be connected to the aforementioned feeding source 12, while the second feeding point F12 may be connected to other feeding sources. The satellite communication signals supported by the first feeding part P11 corresponding to the first feeding point F11 for transceiver under the excitation of the feeding source 12 are different from the satellite communication signals supported by the second feeding part P12 corresponding to the second feeding point F12 for transceiver under the excitation of the feeding source 12. For example, the satellite communication signals supported by the first feeding part P11 for transceiver under the excitation of the feeding source 12 are Beidou satellite communication signals, while the satellite communication signals supported by the second feeding part P12 for transceiver under the excitation of other feeding sources may be other satellite communication signals, such as Galileo satellite communication signals. Or, the satellite communication signals supported by the first feeding part P11 for transceiver under the excitation of the feeding source 12 are Beidou satellite communication signals of a certain frequency band, while the satellite communication signals supported by the second feeding part P12 for transceiver under the excitation of the feeding source 12 may be Beidou satellite communication signals of another frequency band.

[0124] Among them, Figure 12In the figure, an example is schematically shown in which the first feeding point F11 and the second feeding point F12 are both connected to the feed source 12.

[0125] Wherein, the difference between the equivalent electrical length of the first metal segment between the first feeding point F11 and the corresponding first target grounding point G1 and the equivalent electrical length of the second metal segment between the first feeding point F11 and the corresponding second target grounding point G12 is nλ1 / 2 + nλ1 / 4, where λ1 / is the wavelength of the satellite communication signal supported by the first feeding part P11 corresponding to the first feeding point F11 under the excitation of the corresponding feed source. The difference between the equivalent electrical length of the first metal segment between the second feeding point F12 and the corresponding first target grounding point G1 and the equivalent electrical length of the second metal segment between the second feeding point F12 and the corresponding second target grounding point G12 is nλ2 / 2 + nλ2 / 4, where λ2 / is the wavelength of the satellite communication signal supported by the second feeding part P21 corresponding to the second feeding point F12 under the excitation of the corresponding feed source.

[0126] Wherein, Figure 12 Compared with the previous embodiment, the structure shown is that only the feeding point F1 can be multiple, and the structure and working principle of each feeding point F1 and its corresponding first target grounding point G1 and second target grounding point G12 are the same as those of the previous embodiment. For example, in some embodiments, at least one of each feeding point F1 and its corresponding first target grounding point G1 and second target grounding point G12 can also be grounded through a matching unit. Also, for example, a metal sheet 13 is further provided in the space formed by the annular metal part 11, etc. That is, the structure and related content of the first metal segment between each feeding point F1 and the corresponding first target grounding point G1, the second metal segment between the first feeding point F11 and the corresponding second target grounding point G12, etc. are the same as those shown in the foregoing Figures 1 - 11 figures, etc., and will not be elaborated herein specifically.

[0127] Wherein, in some embodiments, when the feeding point F1 includes multiple ones, the first feeding parts P1 corresponding to each feeding point F1 do not overlap with each other. For example, as Figure 12As shown, the first feeding part P11 corresponding to the first feeding point F1 and the second feeding part P12 corresponding to the second feeding point F12 do not coincide. Therefore, the first feeding part P11 of the first feeding point F1 and the second feeding part P21 corresponding to the second feeding point F12 can support the corresponding satellite communication signals separately without interfering with each other. In addition, the non-feeding part P2 of the annular metal part 11 can be the overlapping part of the non-feeding parts P21 corresponding to all the feeding points F1. For example, as described above, the non-feeding part P2 of the annular metal part 11 can be the overlapping part of the first non-feeding part P21 and the second non-feeding part P22. Therefore, at least one third target grounding point G13 can be set to be grounded at the overlapping part of the first non-feeding part P21 and the second non-feeding part P22 to avoid generating clutter.

[0128] Among them, in some embodiments, when there are multiple feeding points F1, the first target grounding points G11 and the second target grounding points G12 corresponding to adjacent feeding points F1 can also coincide. For example, the first target grounding points G11 and the second target grounding points G12 corresponding to the first feeding point F1 and the first target grounding points G11 and the second target grounding points G12 corresponding to the second feeding point F2 can coincide. Therefore, at this time, the non-feeding part P2 included in the annular metal part 11 can be regarded as only two grounding points, that is, the first target grounding point G11 and the second target grounding point G12. Among them, the first target grounding point G11 and the second target grounding point G12, as the demarcation points between the feeding part P1 and the non-feeding part P2, can be regarded as the position points in the feeding part P1 and can also be regarded as the position points in the non-feeding part P2. Among them, the fact that the first feeding part P11 corresponding to the first feeding point F1 and the second feeding part P12 corresponding to the second feeding point F12 do not coincide means that the first feeding part P11 corresponding to the first feeding point F1 and the second feeding part P12 corresponding to the second feeding point F12 coincide at most at the first target grounding point G11 and the second target grounding point G12, and do not coincide at other positions.

[0129] Please refer to Figure 13 , which is another planar schematic diagram of the electronic device 100 in some embodiments of the present application. As Figure 13 shown, the electronic device 100 further includes a rear cover 3, and the annular metal part 11 in any of the foregoing embodiments is disposed on the rear cover 3.

[0130] That is, in some embodiments, the annular metal part 11 can be a structure disposed on the rear cover 3.

[0131] In some embodiments, the rear cover 3 is made of an insulating material, such as glass, ceramic, or plastic, etc.

[0132] In some embodiments, the annular metal piece 11 is a camera decorative ring. That is, in some embodiments, the annular metal piece 11 may specifically be a camera decorative ring. Thus, in some embodiments, the annular metal piece 11 has a structure that shares the camera decorative ring, and there is no need to provide a separate antenna structure, which is beneficial for cost savings and for reducing the volume of the electronic device 100.

[0133] Among them, in some embodiments, the annular metal piece 11 is annular and surrounds to form a space R1. That is, the annular metal piece 11 forms a hollow space R1. Thus, when the annular metal piece 11 is a camera decorative ring, the hollow space R1 allows light to pass through, and it allows the camera to collect light and the light emitted by the flash to pass through.

[0134] Among them, as Figures 1 - 13 shown in the figures, etc., the annular metal piece 11 is circular. That is, the annular metal piece 11 is schematically shown as circular. Obviously, in some embodiments, the annular metal piece 11 can be any shape such as square, oval, D-shaped, triangular, and so on.

[0135] Among them, as mentioned above, in some embodiments, when a metal sheet 13 is provided in the annular metal piece 11, functional holes or notches can be formed at the positions of the metal sheet 13 corresponding to the camera and the flash, so as to provide a light channel, allowing the camera to collect light and the light emitted by the flash to pass through, and not hindering the camera from taking pictures and the flash from filling light.

[0136] In some embodiments, when the annular metal piece 11 is a camera decorative ring, a glass cover plate is provided in the space R1 surrounded by the annular metal piece 11. When a metal sheet 13 is provided in the annular metal piece 11, the metal sheet 13 can also be attached and fixed to the glass cover plate.

[0137] In some embodiments, the annular metal piece 11 can also be any metal piece provided on the rear cover 3. For example, it can be an annular metal piece surrounding the product LOGO (mark) or the company LOGO. In some embodiments, when the annular metal piece 11 is an annular metal piece surrounding the product LOGO (mark) or the company LOGO, and a metal sheet 13 is also provided in the annular metal piece 11, the metal sheet 13 can be hollowed out according to the shape of the LOGO to present the pattern corresponding to the LOGO.

[0138] Obviously, in other embodiments, the annular metal member 11 may also be disposed at other positions of the electronic device 100, for example, on the top D1 of the electronic device 100.

[0139] Herein, the present application takes the annular metal member 11 as a camera decorative ring and disposed on the rear cover 3 as an example for illustration. Among them, the foregoing Figures 11 - 13 are all schematic views from the back side of the electronic device 100, that is, one side of the rear cover 3. Among them, the upper, lower, left, right, etc. in the present application are all orientations viewed from the back side of the electronic device 100.

[0140] In some embodiments, as Figure 13 shown, the electronic device 100 further includes a ground plate 4, wherein the foregoing ground point G1 is specifically grounded by being connected to the ground plate 4.

[0141] In some embodiments, as Figure 13 shown, the electronic device may further include a middle frame 5 and a main board 6, wherein the ground plate 4 may be at least a partial area of the middle frame 5 or at least a partial area of the ground layer in the main board 6. The feed source 12 is disposed on the main board 6.

[0142] Among them, when the annular metal member 11 is disposed on the rear cover 3, the annular metal member 11 is parallel and spaced apart from the ground plate 4 and the main board 6, etc.

[0143] Among them, in some embodiments, the projection of the annular metal member 11 on the ground plate 4 may be within the area range of the ground plate 4.

[0144] Among them, the ground point G1 is disposed on the side of the annular metal member 11 facing the ground plate 4 and the main board 6, so as to facilitate direct grounding through structures such as elastic sheets. The feeding point F1 may also be disposed on the side of the annular metal member 11 facing the ground plate 4 and the main board 6, so as to facilitate connection with the feed source 12 disposed on the main board 6. Among them, the ground plate 4, the middle frame 5, and the main board 6 are all disposed inside the electronic device 100. When the annular metal member 11 is disposed on the rear cover 3, the side of the annular metal member 11 facing the ground plate 4 and the main board 6 is the side facing the inside of the electronic device 100.

[0145] Among them, Figure 13 specifically takes the ground plate 4 as the middle frame 5 for illustration.

[0146] Please refer to Figure 14 , which is the antenna pattern of the first antenna assembly 1 of the electronic device 100 in some embodiments of the present application. Among them, Figure 14The radiation pattern can be obtained through simulation testing when the electronic device 100 includes the first antenna assembly 1 as shown in Figure 3 and performs the transceiver of the satellite communication signal. That is, as shown in Figure 3 , the feeding point F1 is approximately located at a position slightly to the left and above the annular metal part 11 in the Figure 3 shown perspective, and the number of the third target grounding points G13 is two.

[0147] Among them, the darker the color in the radiation pattern, the more it indicates the main direction pointed by the radiation pattern, that is, the main radiation direction of the first antenna assembly 1, namely the beam direction. As shown in Figure 14 , the main direction A1 of the radiation pattern points to the side towards the rear cover 3, that is, points to the back side of the electronic device 100.

[0148] It can be seen that when the feeding point F1 is set at a position slightly to the left and above the annular metal part 11, the main direction A1 of the radiation pattern, that is, the beam direction of the first antenna assembly 1, can point to the back side of the electronic device 100. Thus, when the user holds the electronic device 100 to perform satellite communication, the beam direction of the first antenna assembly 1 will not be blocked and can generally point upward, thereby ensuring the satellite communication performance.

[0149] Please refer to Figure 15 for another antenna radiation pattern of the first antenna assembly 1 of the electronic device 100 in some embodiments of the present application. Among them, Figure 15 The radiation pattern can be obtained through simulation testing when the electronic device 100 includes the first antenna assembly 1 as shown in Figure 5 and performs the transceiver of the satellite communication signal. That is, as shown in Figure 5 , the feeding point F1 is approximately located at a position in the lower right of the annular metal part 11 in the Figure 5 shown perspective, and the number of the third target grounding points G13 is one.

[0150] As shown in Figure 15 , the main direction A1 of the radiation pattern points to the side towards the rear cover 3, that is, points to the back side of the electronic device 100. In addition, it is also more significantly biased towards the side of the top D1 of the electronic device 100.

[0151] It can be seen that when the feeding point F1 is set at the lower right position of the annular metal part 11, the main direction A1 of the radiation pattern, that is, the beam direction of the first antenna assembly 1, can be made to point to the back side of the electronic device 100 and significantly deviate to the side of the top end D1 of the electronic device 100. Thus, when the user holds the electronic device 100 for satellite communication, the beam direction of the first antenna assembly 1 can better point upward, ensuring the satellite communication performance.

[0152] Therefore, from Figure 14 and Figure 15 it can be seen that when the annular metal part 11 is arranged on the back cover 3 of the electronic device 100, when the feeding point F1 is set at different positions of the annular metal part 11, the beam direction during the transmission and reception of satellite communication signals by the first antenna assembly 1 can be made to point to the back side of the electronic device 100. Thus, when the user holds the electronic device 100 for satellite communication, it can be ensured that the beam direction of the first antenna assembly 1 is generally pointing upward, ensuring the satellite communication performance.

[0153] Please refer to Figure 16 , which is another antenna radiation pattern of the first antenna assembly 1 of the electronic device 100 in some embodiments of the present application. Among them, Figure 16 can be the radiation pattern obtained by simulation when the electronic device 100 includes the first antenna assembly 1 as shown in Figure 10 and performs the transmission and reception of satellite communication signals. That is, as shown in Figure 10 , the feeding point F1 can be located at the upper right of the annular metal part 11, and the first antenna assembly 1 further includes a metal sheet 13. The side edge of the metal sheet 13 is adjacent to the 1 / 4 perimeter part of the annular metal part 11 including the feeding point F1 and is also adjacent to another 1 / 4 perimeter part. That is, the metal sheet 13 is generally arranged in the right half of the space R1 surrounded by the annular metal part 11. In addition, the annular metal part 11 may not include the third target grounding point G13.

[0154] Among them, as shown in Figure 16 , when the electronic device 100 includes the structure of the first antenna assembly 1 as shown in Figure 10 , the main direction A1 of the radiation pattern also points to the side facing the back cover 3. Thus, when the user holds the electronic device 100 for satellite communication, the beam direction of the first antenna assembly 1 is generally pointing upward, ensuring the satellite communication performance.

[0155] Please refer to Figure 17 , which is a schematic diagram of the return loss curve of the first antenna assembly 1 of the electronic device 100 in some embodiments of the present application. Among them,Figure 17 It can be a schematic diagram of the return loss curve obtained through simulation testing when the electronic device 100 includes the first antenna assembly 1 as shown and performs the transceiver of the satellite communication signal. Figure 10 Shown is the first antenna assembly 1 and a schematic diagram of the return loss curve obtained through simulation testing when performing the transceiver of the satellite communication signal.

[0156] Among them, Figure 17 The return loss curve S11-1 is shown. Among them, the trough point of the return loss curve S11-1 generally corresponds to the resonant frequency, and the lower the return loss, the higher the antenna radiation efficiency. In some embodiments, the receiving frequency and transmitting frequency of the satellite communication signal supported by the first antenna assembly 1 may be slightly different. Among them, as Figure 17 Shown, in some embodiments, the transmitting frequency of the satellite communication signal supported by the first antenna assembly 1 may be approximately 2.0 GHz, and the receiving frequency may be approximately 2.2 GHz as an example. Obviously, Figure 17 This is just an example, and the first antenna assembly 1 may also support the transceiver of satellite communication signals in any other frequency band. Among them, the receiving frequency and transmitting frequency are the resonant frequencies during reception and transmission respectively.

[0157] From Figure 17 It can be seen that when the electronic device 100 includes the structure of the first antenna assembly 1 as shown, the return losses during the reception and transmission of the satellite communication signal are both significantly lower than -10 dB, the return losses are relatively low, and the antenna radiation efficiencies are both relatively high. Figure 10 Shown is the first antenna assembly 1 and a schematic diagram of the return loss curve obtained through simulation testing when performing the transceiver of the satellite communication signal.

[0158] Among them, when the receiving frequency and transmitting frequency of the satellite communication signal supported by the first antenna assembly 1 are slightly different, the difference between the equivalent electrical length of the first metal segment 111 and the equivalent electrical length of the second metal segment 112 is nλ / 2 + λ / 4, where λ is the wavelength corresponding to the frequency of the satellite communication signal, and n is 0 or a positive integer. The λ can specifically be the wavelength corresponding to the receiving frequency or the transmitting frequency. Since the two are relatively close, the requirement for a 90° phase difference can still be generally met.

[0159] Please refer to Figure 18 , which is a schematic diagram of the total system efficiency curve of the first antenna assembly 1 of the electronic device 100 in some embodiments of this application. Among them, Figure 18 It can be a schematic diagram of the total system efficiency curve obtained through simulation testing when the electronic device 100 includes the first antenna assembly 1 as shown and performs the transceiver of the satellite communication signal. Figure 10 Shown is the first antenna assembly 1 and a schematic diagram of the total system efficiency curve obtained through simulation testing when performing the transceiver of the satellite communication signal.

[0160] Among them, Figure 18The overall system efficiency curve St1 is shown. Among them, the peak point of the overall system efficiency curve St1 generally corresponds to the resonant frequency, and the higher the overall system efficiency curve, the higher the antenna radiation efficiency. In some embodiments, as described above, the receiving frequency and the transmitting frequency of the satellite communication signal supported by the first antenna assembly 1 may be slightly different. Among them, as Figure 18 shown, in some embodiments, the transmitting frequency of the satellite communication signal supported by the first antenna assembly 1 may be approximately 2.0 GHz, and the receiving frequency may be approximately 2.2 GHz as an example for illustration. Obviously, Figure 18 this is only an example, and the first antenna assembly 1 may also support the transceiver of satellite communication signals in any other frequency band.

[0161] Among them, Figure 18 there are actually two overall system efficiency curves in []. These two overall system efficiency curves may be obtained through simulation during receiving and transmitting respectively. However, since each overall system efficiency curve reflects the overall system efficiency of both receiving and transmitting at the same time, and the overall system efficiency corresponding to the receiving frequency and the transmitting frequency is equal, therefore, only one of the overall system efficiency curves St1 is described in this application.

[0162] From Figure 18 it can be seen that when the electronic device 100 includes the structure of the first antenna assembly 1 as Figure 10 shown, the overall system efficiency during the reception and transmission of the satellite communication signal is significantly higher than 6 dB. For example, the overall system efficiency corresponding to the transmitting frequency is -5.5 dB, and the overall system efficiency corresponding to the transmitting frequency is -4.1 dB, and the efficiency is relatively high. Therefore, the antenna radiation efficiency is relatively high.

[0163] Please refer to Figure 19 for the antenna pattern of the first antenna assembly 1 of the electronic device 100 in some embodiments of this application when the electronic device 100 is held. Among them, Figure 19 it may be the pattern obtained through simulation tests when the electronic device 100 includes the first antenna assembly 1 as Figure 10 shown and the electronic device 100 is held close to the head for satellite communication.

[0164] Among them, Figure 19 the patterns at various angles when the electronic device 100 is held close to the head are shown.

[0165] As Figure 19 shown, when the electronic device 100 includes Figure 10When describing the structure of the first antenna assembly 1 as shown, when the electronic device 100 is held close to the head for satellite communication, the main direction A1 of the antenna pattern, that is, the beam direction, also points to the side towards which the rear cover 3 faces, and away from the human head. Thus, when the user holds the electronic device 100 to perform satellite communication, the beam direction of the first antenna assembly 1 is generally upward, ensuring satellite communication performance.

[0166] Therefore, from Figures 16 - 19 it can be seen that by adding the metal sheet 13, the satellite communication performance of the first antenna assembly 1 is better.

[0167] Please refer to Figure 20 , which is a structural block diagram of a part of the internal structure of the electronic device 100 in some embodiments of the present application. As Figure 20 shown, the electronic device 100 includes the first antenna assembly 1 and also includes a second antenna assembly 7.

[0168] Among them, the second antenna assembly 7 is also used to support the reception and transmission of the satellite communication signal, and the beam direction of the second antenna assembly 7 is different from that of the first antenna assembly 1. When the electronic device 100 needs to perform satellite communication, the first antenna assembly 1 works and / or the second antenna assembly 7 is selected to work.

[0169] That is, in some embodiments, in addition to including the first antenna assembly 1 in any of the foregoing embodiments, the electronic device 100 further includes a second antenna assembly 7 that is also used to support the reception and transmission of the satellite communication signal. When the electronic device 100 needs to perform satellite communication, at least one of the first antenna assembly 1 and the second antenna assembly 7 can be selected to work.

[0170] Among them, as described above, the beam direction of the antenna assembly is the main radiation direction. Therefore, the second antenna assembly 7 is also used to support the reception and transmission of the satellite communication signal. When the beam direction of the second antenna assembly 7 is different from that of the first antenna assembly 1, the first antenna assembly 1 can be selected to work and / or the second antenna assembly 7 can be selected to work as needed to ensure satellite communication performance.

[0171] As described above, the beam direction of the first antenna assembly 1 mainly points to the back side of the electronic device 100. In addition, it can also deviate to the side of the non-feed part P2 to a certain extent according to the position of the non-feed part P2. In some embodiments, the second antenna assembly 7 can point to the top D1 of the electronic device 100 and deviate to the side of the display screen of the electronic device 100.

[0172] In some embodiments, as described above, when the first antenna assembly 1 includes only one feeding point F1, the first antenna assembly 1 supports the transceiver of a satellite communication signal. For example, the transceiver of a Beidou satellite communication signal. The satellite communication signal supported by the second antenna assembly 7 for transceiver is the same as the satellite communication signal supported by the first antenna assembly 1 for transceiver.

[0173] In some embodiments, as described above, the first antenna assembly 1 may include a plurality of feeding points F1, and when the feed sources connected to each feeding point F1 are different and support the transceiver of different satellite communication signals, the satellite communication signal supported by the second antenna assembly 7 for transceiver is the same as one of the satellite communication signals supported by the first antenna assembly 1 for transceiver.

[0174] For example, as described above, when the first antenna assembly 1 includes the first feeding point F11 and the second feeding point F12, the satellite communication signal supported by the first feeding part P11 for transceiver under the excitation of the feed source 12 is a Beidou satellite communication signal, while the satellite communication signal supported by the second feeding part P12 for transceiver under the excitation of other feed sources may be other satellite communication signals, such as Galileo satellite communication signals. Or, the satellite communication signal supported by the first feeding part P11 for transceiver under the excitation of the feed source 12 is a Beidou satellite communication signal in a certain frequency band, while the satellite communication signal supported by the second feeding part P12 for transceiver under the excitation of the feed source 12 may be a Beidou satellite communication signal in another frequency band. At this time, the satellite communication signal supported by the second antenna assembly 7 for transceiver may be a Beidou satellite communication signal and has the same frequency band as the satellite communication signal supported by the first feeding part P11 for transceiver under the excitation of the feed source 12.

[0175] In some embodiments, when the first antenna assembly 1 includes a plurality of feeding points F11, and when the feed sources connected to each feeding point F1 are different and support the transceiver of different satellite communication signals, when selecting the first antenna assembly 1 to work, it may be to select the entire first antenna assembly 1 to work, or it may be to only select the feeding part P1 corresponding to one feeding point whose supported transceiver satellite communication signal is the same as that of the second antenna assembly 7 to work.

[0176] In some embodiments, when the first antenna assembly 1 includes a plurality of feeding points F1, and when the feed sources connected to each feeding point F1 are the same, for example, all are the feed source 12, and support the transceiver of the same satellite communication signal, the satellite communication signal supported by the second antenna assembly 7 for transceiver is the same as the satellite communication signal supported by the first antenna assembly 1 for transceiver.

[0177] In some embodiments, the first antenna assembly 1 and / or the second antenna assembly 7 may be selected to operate according to the state of the electronic device 100, and the state of the electronic device 100 includes at least one of the placement state of the electronic device 100 and the signal quality states of the first antenna assembly 1 and the second antenna assembly 7.

[0178] In some embodiments, the placement state of the electronic device 100 may include placement states such as back facing up, front facing up, close to the human head, and so on.

[0179] Please refer to Figure 21 , which is a further structural block diagram of a part of the internal structure of the electronic device 100 in some embodiments of the present application. As Figure 21 shown, the electronic device 100 includes the first antenna assembly 1, the second antenna assembly 7, and also includes a controller 8 and a sensor 9.

[0180] The controller 8 is used to control the selection of at least one of the first antenna assembly 1 and the second antenna assembly 7 to operate when the electronic device 100 needs to perform satellite communication. That is, in some embodiments, the selection of at least one of the first antenna assembly 1 and the second antenna assembly 7 to operate may be under the control of the controller 8.

[0181] In some embodiments, the controller 8 may select at least one of the first antenna assembly 1 and the second antenna assembly 7 to operate according to the state of the electronic device 100.

[0182] Among them, the sensor 9 is used to detect the placement state of the electronic device 100 to generate a corresponding induction signal. The controller 8 is connected to the sensor 9 and is used to receive the induction signal generated by the sensor 9 to determine the placement state of the electronic device 100, and may control the selection of the first antenna assembly 1 and / or the second antenna assembly 7 to operate according to the placement state of the electronic device 100.

[0183] In some embodiments, the sensor 9 may include a proximity sensor such as an infrared sensor. When the controller 8 receives an induction signal generated by the proximity sensor detecting that a human body is approaching the electronic device 100, it determines that a human body is currently detected approaching the electronic device 100. The sensor 9 may be disposed on one side of the display screen of the electronic device 100 and near the top end D1 of the electronic device 100. When the distance between the detected human body and the proximity sensor itself is less than a preset distance, it is determined that a human body is detected approaching the electronic device 100, and an induction signal is generated. Among them, determining that a human body is currently detected approaching the electronic device 100 mainly means that the head of the person approaches the electronic device 100. Generally speaking, in scenarios such as making a phone call, the user will bring the front side of the electronic device 100, that is, the side of the display screen, close to human body parts such as the head. Therefore, the sensor 9 may be disposed on one side of the display screen of the electronic device 100. When the distance between the detected human body and the sensor 9 itself is less than a preset distance, it means that the human head approaches the electronic device 100, that is, in a state of approaching the human head, and a corresponding induction signal is generated.

[0184] As described above, the beam direction of the first antenna assembly 1 is directed to the back side of the electronic device 100. In some embodiments, the second antenna assembly 7 may be directed to the top end D1 of the electronic device 100 and biased towards one side of the display screen of the electronic device 100. Therefore, when in a state of approaching the human head, the beam direction of the second antenna assembly 7 will be blocked by the head, resulting in a greater impact on the communication performance. However, the beam direction of the first antenna assembly 1 is directed to the back side of the electronic device 100 and will not be affected. Therefore, the controller 8 can control and select the first antenna assembly 1 to operate.

[0185] The sensor 9 may further include an attitude sensor such as an acceleration sensor. When the controller 8 detects through the attitude sensor that the placement state of the electronic device 100 is face-up placement, that is, the placement state with the rear cover 3 facing up, it controls and selects the first antenna assembly 1 to operate. When the controller 8 detects through the attitude sensor that the placement state of the electronic device 100 is back-up placement, that is, the placement state with the display screen of the electronic device 100 facing up, it controls and selects the second antenna assembly 7 to operate.

[0186] In some embodiments, the signal quality can be reflected by signal parameter values such as signal strength values, signal-to-noise ratio values, etc. In some embodiments, the controller 8 is further configured to obtain at least one signal parameter value such as the signal strength value, the signal-to-noise ratio value, etc. of the satellite communication signal when one of the currently selected first antenna assembly 1 and the second antenna assembly 7 is operating, and compare the at least one signal parameter value such as the signal strength value, the signal-to-noise ratio value, etc. with the corresponding signal parameter threshold. When it is determined that at least one signal parameter value such as the signal strength value, the signal-to-noise ratio value, etc. currently obtained is lower than the corresponding signal parameter threshold, it is determined that the signal quality of one of the currently selected first antenna assembly 1 and the second antenna assembly 7 is lower than the preset threshold, and the controller controls to switch and select the other one of the second antenna assembly 7 and the first antenna assembly 1 to operate.

[0187] In some embodiments, the controller 8 is further configured to control the selection of the first antenna assembly 1 and the second antenna assembly 7 to operate simultaneously under some specific conditions. For example, after switching to the other one of the second antenna assembly 7 and the first antenna assembly 1 to operate, the controller 8 is further configured to obtain at least one signal parameter value such as the signal strength value, the signal-to-noise ratio value, etc. of the satellite communication signal when the other one of the currently selected first antenna assembly 1 and the second antenna assembly 7 is operating, and compare the at least one signal parameter value such as the signal strength value, the signal-to-noise ratio value, etc. with the corresponding signal parameter threshold. When it is determined that at least one signal parameter value such as the signal strength value, the signal-to-noise ratio value, etc. currently obtained is lower than the corresponding signal parameter threshold, it is determined that the signal quality of the other one of the currently selected first antenna assembly 1 and the second antenna assembly 7 is also lower than the preset threshold, and the controller controls to select the second antenna assembly 7 and the first antenna assembly 1 to operate simultaneously, thereby improving the satellite communication quality.

[0188] Please refer to Figure 22 , which is a structural block diagram of a more specific internal structure of the electronic device 100 in some embodiments of the present application. As Figure 22 shown, the electronic device 100 includes the first antenna assembly 1, the second antenna assembly 7, and a controller 8. The electronic device 100 further includes a switch module S1. The first antenna assembly 1 further includes a feed 12. The second antenna assembly 7 includes an antenna radiation structure 71. The switch module S1 is connected between the feed 12, the feeding point F1 of the annular metal part 11, and the antenna radiation structure 71. The switch module S1 is configured to establish an electrical connection between the feed 12 and the annular metal part 11, and / or establish an electrical connection between the feed 12 and the antenna radiation structure 71, so as to control the selection of the first antenna assembly 1 to operate and / or the second antenna assembly 7 to operate.

[0189] That is, in some embodiments, since the satellite communication signal supported for transceiver by the second antenna assembly 7 is the same as one of the satellite communication signals supported for transceiver by the first antenna assembly 1, and the structure mainly used for selection and switching is the one that supports the transceiver of the same satellite communication signal, the feeds of the first antenna assembly 1 and the second antenna assembly 7 can be the same. Thus, by connecting the feed 12 to the radiation structure in different antenna assemblies or simultaneously connecting it to the radiation structures of all antenna assemblies through the switch module S1, different antenna assemblies can be selected to work, or all antenna assemblies can be selected to work simultaneously.

[0190] Among them, as Figure 22 shown, the switch module S1 includes a first switch S11 and a second switch S12. The first switch S11 is connected between the feed 12 and the feed point F1 of the annular metal part 11 of the first antenna assembly 1, and the second switch S12 is connected between the feed 12 and the antenna radiation structure 71 of the second antenna assembly 7. The first switch S11 and the second switch S12 can be in corresponding on or off states, so as to establish an electrical connection between the feed 12 and the feed point F1 of the annular metal part 11, and / or establish an electrical connection between the feed 12 and the antenna radiation structure 71, and select the first antenna assembly 1 to work and / or the second antenna assembly 7 to work.

[0191] Specifically, when the first switch S11 is on and the second switch S12 is off, an electrical connection is established between the feed 12 and the annular metal part 11, and the electrical connection between the feed 12 and the antenna radiation structure 71 is disconnected. At this time, the first antenna assembly 1 is selected to work. When the first switch S11 is off and the second switch S12 is on, the electrical connection between the feed 12 and the annular metal part 11 is disconnected, and the electrical connection between the feed 12 and the antenna radiation structure 71 is connected. At this time, the second antenna assembly 7 is selected to work. Among them, when both the first switch S11 and the second switch S12 are on, the feed 12 is electrically connected to both the annular metal part 11 and the antenna radiation structure 71 at the same time. At this time, the first antenna assembly 1 and the second antenna assembly 7 are selected to work simultaneously.

[0192] Among them, in some embodiments, when the electronic device further includes the controller 8, the controller 8 is used to control the switch module S1 to establish an electrical connection between the feed 12 and the annular metal part 11, and / or establish an electrical connection between the feed 12 and the antenna radiation structure 71, so as to control the selection of the operation of the first antenna assembly 1 and / or the second antenna assembly 7. Specifically, the controller 8 is connected to the first switch S11 and the second switch S12, and the first switch S11 and the second switch S12 are controlled to be in corresponding on or off states.

[0193] Among them, the first switch S11 and the second switch S12 are numerically controlled switches, such as MOS transistors, BJT transistors, etc., and can be in an on or off state when receiving corresponding level signals from the controller 8.

[0194] Among them, Figure 22 Taking the example that the first antenna assembly 1 only includes one feeding point F1 for illustration.

[0195] Please refer to Figure 23 , which is another structural block diagram of the more specific internal structure of the electronic device 100 in some embodiments of the present application.

[0196] Among them, Figure 23 The difference from Figure 22 is that the annular metal part 11 of the first antenna assembly 1 includes multiple feeding points F1. For example, as Figure 23 shown, the annular metal part 11 includes a first feeding point F11 and a second feeding point F12, and the feeds connected to each feeding point F1 are different. As described above, the satellite communication signal supported by the second antenna assembly 7 for transceiver is the same as one of the satellite communication signals supported by the first antenna assembly 1 for transceiver. Specifically, the feeding part P1 corresponding to the first feeding point F11 supports the transceiver of the same satellite communication signal as the second antenna assembly 7 under the excitation of the feed 12. At this time, the first switch S11 is connected between the feed 12 and the first feeding point F11 of the annular metal part 11 of the first antenna assembly 1, the second switch S12 is connected between the feed 12 and the antenna radiation structure 71 of the second antenna assembly 7, and the first switch S11 and the second switch S12 are in corresponding on or off states, so as to establish an electrical connection between the feed 12 and the first feeding point F11 of the annular metal part 11, and / or establish an electrical connection between the feed 12 and the antenna radiation structure 71, and select the operation of at least the feeding part P1 corresponding to the first feeding point F11 in the first antenna assembly 1 and / or select the operation of the second antenna assembly 7.

[0197] Among them, in some embodiments, when the annular metal member 11 includes a first feeding point F11 and a second feeding point F12, and the feeding sources connected to each feeding point F1 are different, the first antenna assembly 1 may further include another feeding source 16. The second feeding point F12 is connected to the another feeding source 16, and under the excitation of the another feeding source 16, it supports the transceiver of other satellite communication signals.

[0198] Thus, in some embodiments, when the annular metal member 11 includes a first feeding point F11 and a second feeding point F12, and the feeding sources connected to each feeding point F1 are different, the switch module S1 may be only used to switch the electrical connection between the feeding source 12 and the antenna radiation structure 71 of the second antenna assembly 7 and the first feeding point F11 corresponding to the feeding part P1 that supports the transceiver of the same satellite communication signal.

[0199] Similarly, when the electronic device further includes the controller 8, it is connected to the first switch S11 and the second switch S12 through the controller 8 to control the first switch S11 and the second switch S12 to be in corresponding on or off states.

[0200] Please refer to Figure 24 , which is another structural block diagram of the more specific internal structure of the electronic device 100 in some embodiments of the present application.

[0201] Among them, Figure 24 The difference from Figure 22 is that the annular metal member 11 of the first antenna assembly 1 includes a plurality of feeding points F1. For example, as Figure 23 shown, the annular metal member 11 includes a first feeding point F11 and a second feeding point F12, where Figure 24 The difference from Figure 23 is that the feeding sources connected to each feeding point F1 are the same, that is, they are all the feeding source 12, and support the transceiver of the same satellite communication signal. At this time, the satellite communication signal supported by the second antenna assembly 7 for transceiver is the same as the satellite communication signal supported by the first antenna assembly 1 for transceiver.

[0202] Such as Figure 24As shown, the first switch S11 is connected between the common node N1 of the first feed point F11 and the second feed point F12 of the annular metal part 11 of the feed source 12 and the first antenna assembly 1. The second switch S12 is connected between the feed source 12 and the antenna radiation structure 71 of the second antenna assembly 7. The first switch S11 and the second switch S12 are in corresponding on or off states, so as to establish an electrical connection between the feed source 12 and the first feed point F11 and the second feed point F12 of the annular metal part 11, and / or establish an electrical connection between the feed source 12 and the antenna radiation structure 71, so as to select the first antenna assembly 1 to work and / or the second antenna assembly 7 to work.

[0203] Similarly, when the electronic device also has the controller 8, it is connected to the first switch S11 and the second switch S12 through the controller 8, so as to control the first switch S11 and the second switch S12 to be in corresponding on or off states.

[0204] Please refer to Figure 25 , which is a schematic plan view showing the second antenna assembly 7 in some embodiments of the electronic device 100 of the present application.

[0205] Among them, as Figure 25 shown, in some embodiments, the antenna radiation structure 71 of the second antenna assembly 7 includes radiation branches 710 and the aforementioned ground plane 4.

[0206] Among them, the radiation branches 710 can be arranged at the top D1 of the electronic device 100. The radiation branches 710 include an opposite ground end D11 and an open end D12. The ground end D11 is grounded. Specifically, the ground end D11 is connected to the ground plane 4 to be grounded. The radiation branches 710 also include a feed point F2, and the feed point F2 is arranged between the ground end D11 and the open end D12. In some embodiments, the feed point F2 is arranged close to the open end D12. For example, the interval between the feed point F2 and the open end D12 is less than a preset distance, such as 5 mm (millimeters).

[0207] Among them, the radiation branches 710 form an inverted F antenna (IFA, inverted F antenna). The electrical length of the radiation branches 710 is 1 / 4 of the wavelength of the supported satellite communication signal, so as to support the transceiver of the satellite communication signal. In some embodiments, the feed point F2 can also be connected to the feed source 12, so as to support the transceiver of the satellite communication signal under the excitation of the feed source 12.

[0208] Among them, the aforementioned controller 8 controls the switch module S1 to establish an electrical connection between the feed 12 and the antenna radiation structure 71, specifically, controls the switch module S1 to establish an electrical connection between the feed 12 and the feeding point F2 of the radiation stub 710.

[0209] Among them, the extending direction of the radiation stub 710 is parallel to the end face of the top end D1 of the electronic device 100. The radiation stub 710 generates a current conducting along the extending direction of the radiation stub 710 under the excitation of the feed 12. In addition, since the grounding end D11 of the radiation stub 710 is connected to the ground plane 4, it also excites the ground plane 4 to generate a current in a direction perpendicular to the extending direction of the radiation stub 710.

[0210] Thus, the radiation stub 710 and the ground plane 4 are equivalent to two perpendicular antenna radiation arms. And because a phase difference is introduced from the feeding point F2 through the radiation stub 710 to the ground plane 4, there is a phase difference between the current in the radiation stub 710 and the current in the direction perpendicular to the extending direction of the radiation stub 710 generated by exciting the ground plane 4, for example, approximately 90°. Thus, the second antenna assembly 7 can exhibit circular polarization or elliptical polarization characteristics to form a circular polarization or elliptical polarization antenna, so as to support the transceiver of the satellite communication signal.

[0211] In some embodiments, the frame of the electronic device 100 can be a metal frame, and the radiation stub 710 can be a metal frame segment formed by opening the slit X1 in the metal frame of the electronic device 100.

[0212] Among them, in some other embodiments, the frame of the electronic device 100 is a non-metal frame, and the radiation stub 710 is a metal segment disposed in the frame of the electronic device 100.

[0213] That is, in some other embodiments, the frame of the electronic device 100 can also be a non-metal frame with low conductivity such as plastic, plastic, ceramic, etc. The radiation stub 710 is a metal segment disposed in the frame of the electronic device 100. Among them, the radiation stub 710 can be embedded in the frame of the electronic device 100 or disposed on the inner side surface of the frame of the electronic device 100.

[0214] Please refer to Figure 26 and Figure 27 , Figure 26 which is a simplified schematic diagram of the second antenna assembly 7 of the electronic device 100 in some embodiments of the present application. Figure 27 which is a schematic diagram of the current distribution of the second antenna assembly 7 of the electronic device 100 in some embodiments of the present application.

[0215] Among them, as Figure 26 shown, the second antenna assembly 7 may include two perpendicular antenna radiation arms, namely the radiation stub 710 and the ground plane 4. As Figure 26 and Figure 27 shown, under the excitation of the feed source 12, the radiation stub 710 generates a current i21 that conducts along the extension direction of the radiation stub 710, while the ground plane 4 is excited to generate a current i22 in a direction perpendicular to the extension direction of the radiation stub 710.

[0216] That is, under the excitation of the feed source 12, the radiation stub 710 generates a current i21 that conducts along the extension direction of the radiation stub 710. Since the grounded end D11 of the radiation stub 710 is connected to the ground plane 4, the ground plane 4 is also excited to generate a current i22 in a direction perpendicular to the extension direction of the radiation stub 710.

[0217] Please refer to Figure 28 , which is the antenna pattern of the second antenna assembly 7 of the electronic device 100 in some embodiments of this application. Among them, Figure 28 it can be the pattern obtained by simulation tests when the second antenna assembly 7 included in the electronic device 100 shown in Figure 25 receives and transmits satellite communication signals.

[0218] Among them, the darker the color in the pattern, the direction mainly pointed to by the pattern, that is, the main radiation direction of the second antenna assembly 7, namely the beam direction. Among them, Figure 28 the display screen 20 of the electronic device 100 is also schematically shown. As Figure 28 shown, the main direction A1 of the pattern points to the top D1 of the electronic device 100 and is biased towards one side of the display screen 20.

[0219] Thus, when the user holds the electronic device 100 and the display screen 20 of the electronic device 100 faces upward, the beam direction of the second antenna assembly 7 generally points upward, and the satellite communication performance can be ensured in the normal use scenario of the electronic device 100.

[0220] Therefore, as described above, the beam direction of the second antenna assembly 7 is different from that of the first antenna assembly 1, and at least one of the second antenna assembly 7 and the first antenna assembly 1 can be selected to work according to needs, ensuring good satellite communication quality in different scenarios.

[0221] Among them, Figure 25 this is only one implementation structure of the second antenna assembly 7, and the second antenna assembly 7 can also be other structures that support the reception and transmission of satellite communication signals.

[0222] See also Figure 29 , is another simple structural diagram of the second antenna component 7 of the electronic device 100 in some embodiments of the present application. The antenna radiation structure 71 of the second antenna component 7 may include a first radiation branch 711, a second radiation branch 712, and a connecting branch 713. The connecting branch 713 is connected between the first radiation branch 711 and the second radiation branch 712, and the first radiation branch 711, the second radiation branch 712, and the first connecting branch 713 form a semi-annular structure with one end open. Among them, the first radiating branch 711 forms a first monopole antenna T1, the first radiating branch 711 and the first connecting branch 713 and the second radiating branch 712 form a first slot antenna T2, the first monopole antenna T1 works in a first monopole antenna mode, the first slot antenna T2 works in a first slot antenna mode, the phase difference between the first monopole antenna mode and the first slot antenna mode is 90°, the first monopole antenna T1 and the first slot antenna T2 cooperate to form a circularly polarized antenna or an elliptically polarized antenna to support the transmission and / or reception of the satellite communication signal.

[0223] The semi-annular structure with an open end formed by the first radiating branch 711, the second radiating branch 712 and the connecting branch 713 is formed by processing a metal body, and specifically, by slotting the middle of the metal body.

[0224] In some embodiments, the frame of the electronic device 100 is a metal frame, and the semi-annular structure with one end open formed by the first radiating branch 711, the second radiating branch 712, and the connecting branch 713 may be formed by grooving the upper frame at the top of the electronic device 100. That is, the metal body in the aforementioned "the semi-annular structure with one end open formed by the first radiating branch 711, the second radiating branch 712, and the connecting branch 713 is formed by processing a metal body" may be the metal frame of the electronic device 100.

[0225] In other embodiments, the electronic device 100 may also include a non-metallic frame, and the first radiation branch 711, the second radiation branch 712, and the connecting branch 713 in the aforementioned second antenna component 7 are metal segments disposed in the non-metallic frame of the electronic device 100. That is, in other embodiments, the frame of the electronic device 100 may also be a non-metallic frame with low electrical conductivity such as plastic, ceramic, etc. The first radiation branch 711, the second radiation branch 712, and the connecting branch 713 in the aforementioned second antenna component 7 are metal segments disposed in the non-metallic frame of the electronic device 100.

[0226] Wherein, when the frame of the electronic device 100 is a frame made of non-metallic materials with low electrical conductivity such as plastic, plastic, or ceramic, the first radiation branch 711, the second radiation branch 712, and the connecting branch 713 in the aforementioned second antenna assembly 7 may be embedded in the frame of the electronic device 100 or disposed on the inner side surface of the frame of the electronic device 100.

[0227] Wherein, the Figure 29 may be a schematic diagram of the second antenna assembly 7 viewed from one side of the top end D1 of the electronic device 100.

[0228] Wherein, as Figure 29 shown, the first radiation branch 711 includes an opposite first end 711a and a second end 711b, the second radiation branch 712 includes an opposite third end 712a and a fourth end 712b, the connecting branch 713 is connected between the second end 711b of the first radiation branch 711 and the third end 712a of the second radiation branch 712, a feeding point F2 is disposed at the first end 711a of the first radiation branch 711 or a position close to the first end 711a, the feeding point F2 is used to connect to the feed source 12, and a grounding point G0 is disposed at the fourth end 712b of the second radiation branch 712 or a position close to the fourth end 712b for grounding, for example, connecting to the aforementioned ground plane 4.

[0229] Wherein, the specific form of the first monopole antenna T1 of the present application may be formed by a portion between the feeding point F2 and the second end 711b of the first radiation branch 711. Since the feeding point F1 is disposed at the first end 711a of the first radiation branch 711 or a position close to the first end 711a, therefore, the first monopole antenna T1 can be regarded as being formed by the first radiation branch 711. The first slot antenna T2 may specifically be formed by a portion between the first radiation branch 711, the connecting branch 713, and the third end 712a of the second radiation branch 712 to the grounding point G0. Since the grounding point G0 is disposed at the fourth end 712b of the second radiation branch 712 or a position close to the fourth end 712b, therefore, the portion between the third end 712a of the second radiation branch 712 and the grounding point G0 is substantially the second radiation branch 712. Therefore, the first slot antenna T2 can be regarded as being formed by the first radiation branch 711, the first connecting branch 713, and the second radiation branch 712.

[0230] In some embodiments, the sum of the electrical length of the connection stub 713 and the electrical length from the third end 712a of the second radiation stub 712 to the ground is nλ / 2 + λ / 4, and the sum of the electrical length of the connection stub 713 and the electrical length from the third end 712a of the second radiation stub 712 to the ground is exactly the electrical length difference between the first slot antenna T2 and the first monopole antenna T1. Thus, the phase difference between the first monopole antenna mode and the first slot antenna mode can be ±90°, where λ is the wavelength corresponding to the frequency of the satellite communication signal, and n is 0 or a positive integer.

[0231] Wherein, the present application further provides an antenna assembly, and the antenna assembly may be the first antenna assembly 1 in any of the foregoing embodiments. That is, the antenna assembly includes the first antenna assembly 1 including a ring-shaped metal member 11 and a feed source 12. The ring-shaped metal member 11 includes a feeding point F1 and at least two grounding points G1. Among them, the at least two grounding points G1 are used for grounding, and the at least two grounding points G1 include a first target grounding point G11 and a second target grounding point G12 that are located on both sides of the feeding point F1 and are closest to the feeding point F1. The feed source 12 is connected to the feeding point F1 and is used to excite a first excitation current that conducts along the first metal segment 111 between the feeding point F1 and the first target grounding point G1 and a second excitation current that conducts along the second metal segment 112 between the feeding point F1 and the second target grounding point G12. The phase difference between the first excitation current and the second excitation current is 90°, so that the ring-shaped metal member 11 forms a circularly polarized or elliptically polarized antenna, and supports the reception and transmission of satellite communication signals.

[0232] Wherein, the antenna assembly may specifically include the structure of the first antenna assembly 1 in any of the foregoing embodiments, and for more specific content, reference may be made to the foregoing description.

[0233] Wherein, the controller 8 may be a central processing unit, a microcontroller, a single-chip microcomputer, a digital signal processor, etc.

[0234] Wherein, the electronic device 100 of the present application may be any electronic device with an antenna such as a mobile phone or a tablet computer.

[0235] The antenna assembly / first antenna assembly 1 and the electronic device 100 of the present application are configured by providing a feeding point F1 and at least two grounding points G1 for grounding on the annular metal part 11. The at least two grounding points G1 include a first target grounding point G11 and a second target grounding point G12 that are located on both sides of the feeding point F1 and are the closest to the feeding point F1. When the feed source 12 excites the annular metal part 11 through the feeding point F1, a first excitation current that conducts along a first metal segment 111 between the feeding point F1 and the first target grounding point G11 and a second excitation current that conducts along a second metal segment 112 between the feeding point F1 and the second target grounding point G12 can be excited in the annular metal part 11. The phase difference between the first excitation current and the second excitation current is 90°, causing the annular metal part 11 to form a circularly polarized or elliptically polarized antenna, thereby supporting the reception and transmission of satellite communication signals. Thus, in the present application, by exciting the current to conduct along two parts between the feeding point F1 and the grounding points G1 on both sides, and with a 90° phase difference between the currents on the two parts, the annular metal part 11 can be caused to form a circularly polarized or elliptically polarized antenna, which has a simple structure and a relatively small overall volume, achieving a more compact antenna structure.

[0236] In addition, since the first antenna assembly 1 is disposed on one side of the rear cover 3 of the electronic device 100, it can effectively reduce human interference and improve the quality of satellite communication in the usage scenario where the electronic device 100 is close to the user for making calls.

[0237] Among them, each embodiment of the present application may have different focuses. For the content not detailed in some embodiments, reference may be made to the relevant content of other embodiments.

Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application; without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
