Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of communication, and particularly relates to an antenna module, an electronic device and an antenna parameter adjustment method. BACKGROUND

[0002] Satellite communication is a wireless communication mode using a satellite as a relay station, and is a communication mode with advantages of flexible networking, reliable link, wide signal coverage range, and no geographical restrictions. Civil satellite communication can provide voice, video, data and other services. The frequency band of satellite communication includes a wide frequency band of 1 GHz-40 GHz, and the frequency band for mobile communication mainly includes L band (1-2 GHz) and S band (2-4 GHz).

[0003] In the related art, manufacturers of electronic devices such as mobile phones begin to introduce satellite communication into smart mobile terminals, and satellite communication begins to enter the general electronic consumer field and begins to expand. However, in the related art, when a user of an electronic device uses satellite communication, the user needs to align the electronic device to a specified small angle domain for satellite search and connection, and the duration is relatively long. When the orientation angle of the electronic device slightly shakes, satellite search failure or connection failure may occur. SUMMARY

[0004] The purpose of the embodiments of the present application is to provide an antenna module, an electronic device and an antenna parameter adjustment method, which can adjust the radiation direction of the antenna module, and when the antenna module is used as a satellite antenna, even if the orientation angle of the antenna module slightly shakes during satellite search and connection, the satellite search and connection can be successfully performed by adjusting the radiation direction of the antenna module.

[0005] In a first aspect, the embodiments of the present application provide an antenna module, which comprises: a first radiator, a second radiator, a first feeding port and a first matching module.

[0006] The second radiator comprises a first segment and a second segment, the extension direction of the first segment is the same as the extension direction of the first radiator, and the included angle between the extension direction of the second segment and the extension direction of the first segment is greater than 0° and less than 180°.

[0007] The first end of the first radiator is electrically connected to the first feeding port, the first end of the first segment has a first break joint between the second end of the first radiator and the first end of the first segment, the second end of the first segment is electrically connected to the first end of the second segment, and the second end of the second segment is grounded.

[0008] The first matching module is electrically connected to the first segment.

[0009] The electrical parameter of the first matching module is adjustable, and the electrical parameter includes at least one of capacitance, inductance and resistance.

[0010] The first matching module is configured to adjust at least one of a position of a point of strongest current, a current amplitude and a current phase on the second radiator, so as to adjust a radiation direction of the antenna module.

[0011] In a second aspect, an electronic device is provided, which includes the antenna module according to the first aspect.

[0012] In a third aspect, an antenna parameter adjustment method is provided, which is applied to the electronic device according to the second aspect, and includes:

[0013] In a process of establishing a satellite communication connection, spatial posture information of the electronic device is acquired;

[0014] According to the spatial posture information, a current radiation direction of the antenna module is determined;

[0015] According to a difference between the current radiation direction of the antenna module and a target direction, an electrical parameter of the first matching module is adjusted, so as to reduce the difference between the current radiation direction of the antenna module and the target direction, where the target direction is a direction in which a satellite is located.

[0016] In the embodiments of the present application, the first radiator and the second radiator constitute a two-element antenna array, and a directional diagram of the two-element antenna array is determined by a distance between a point of strongest current of the first radiator and a point of strongest current of the second radiator, current amplitudes on the first radiator and the second radiator, and a phase difference between a current on the first radiator and a current on the second radiator. By adjusting the electrical parameter of the first matching module, at least one of the position of the point of strongest current on the second radiator, the current amplitude and the current phase can be changed, and thus the radiation direction of the antenna module can be changed by adjusting the electrical parameter of the first matching module. In this way, when the antenna module is used as a satellite antenna, even if a slight shaking occurs in an orientation angle of the antenna module during a satellite searching and connection process, the radiation direction of the antenna module can be adjusted to be close to a direction in which a satellite is located by adjusting the electrical parameter of the first matching module, so as to successfully perform the satellite searching and connection.

[0044] The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0045] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0046] To ensure good communication capabilities, the antennas on mobile phones and other electronic devices usually need to focus on the gain pattern, requiring high gain in the optimal radiation direction. However, the available beamwidth of a high-gain pattern is narrow, which means that users need to hold the phone in a nearly fixed posture for a long time when communicating or establishing a communication connection.

[0047] For example: Figure 1 As shown, where, Figure 1 The left side of the middle section shows the gain curve for narrow beams. Figure 1 The right side of the middle section shows the gain curve of the wide beam. Figure 1 It is evident that narrow beams offer higher gain but have a narrower usable beamwidth, while wide beams, although offering a wider usable beamwidth, suffer from reduced gain. During communication, lower gain results in lower communication quality. Therefore, wide beams are unsuitable for satellite communication; instead, narrow beams are used to improve communication quality. However, narrow beams concentrate energy into a very small angular region, requiring the mobile phone to maintain a fixed alignment with the satellite for an extended period during satellite search or connection processes.

[0048] This application provides an antenna module with adjustable radiation direction. During satellite search or connection operations, any difference in angular distance between the antenna module's radiation direction and the satellite's direction caused by changes in the user's hand position can be compensated for by dynamically adjusting the antenna module's radiation direction. This ensures the antenna module's radiation direction remains aligned with the satellite's direction or reduces the difference. Therefore, even with slight fluctuations in the antenna module's orientation angle, satellite search and connection can be successfully performed by adjusting the antenna module's radiation direction.

[0049] It should be noted that, in the embodiments of this application, the radiation direction of the antenna module usually refers to the main lobe radiation direction or the optimal radiation direction of the antenna module. The optimal radiation direction means the beam radiation direction with a gain greater than or equal to a preset threshold. The preset threshold can be the minimum gain value that meets the communication requirements.

[0050] The antenna module, the electronic device and the antenna parameter adjustment method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings, specific embodiments and application scenarios.

[0051] Referring to Figure 2 or Figure 14 The antenna module provided by the embodiments of the present application comprises a first radiator AC, a second radiator DF, a first feeding port 10 and a first matching module.

[0052] The second radiator DF comprises a first segment DE and a second segment EF, the extension direction of the first segment DE is the same as the extension direction of the first radiator AC, and the included angle between the extension direction of the second segment EF and the extension direction of the first segment DE is greater than 0° and less than 180°.

[0053] The first end A of the first radiator AC is electrically connected with the first feeding port 10, the first end D of the first segment DE is electrically connected with the second end E of the first segment DE (i.e., the first segment DE and the second segment EF can be an integral structure), and the second end F of the second segment EF is grounded.

[0054] The first matching module is electrically connected with the first segment DE.

[0055] The electrical parameter of the first matching module is adjustable, and the electrical parameter comprises at least one of capacitance, inductance and resistance.

[0056] The first matching module is used for adjusting at least one of the position of the strongest point of the current, the current amplitude and the current phase on the second radiator DF, so as to adjust the radiation direction of the antenna module.

[0057] It is worth mentioning that the first matching module can comprise at least one of the first matching sub-module 20 as shown in Figure 2 and the second matching sub-module 110 as shown in Figure 14 , or can comprise any matching module other than the first matching sub-module 20 and the second matching sub-module 110, as long as the first matching module is electrically connected with the first segment DE. For the convenience of description, in the following embodiments, the first matching module is usually taken as an example to illustrate that the first matching module comprises the first matching sub-module 20, or comprises the first matching sub-module 20 and the second matching sub-module 110, which does not constitute a specific limitation.

[0058] In some embodiments, the first matching module is electrically connected with the first segment DE, and can be electrically connected at any position on the first segment DE. In addition, the first matching module can further include other ends, which can be electrically connected with the first radiator AC, grounded, electrically connected with other feeding ports, or left floating, without specific limitation here. It should be noted that the arrow pointing to the radiator in the drawings of the present application indicates the position of the feed point on the radiator, such as Figure 3 In some embodiments, one feed point can be arranged at the first position 40, and another feed point can be arranged at the second position 82. In addition, the feed source, the feeding port and the matching module in the embodiments of the present application are arranged on a circuit board, such as a mainboard, and the feed source is electrically connected with the feeding port through the matching module to feed the radiator through the feeding port.

[0059] In some embodiments, the matching module can include at least one of an adjustable capacitor, an adjustable resistor and an adjustable inductor, so that the electrical parameters of the matching module can be adjusted by adjusting at least one of the adjustable capacitor, the adjustable resistor and the adjustable inductor.

[0060] In some other embodiments, the matching module can switch the matching branches through a switching switch to adjust the electrical parameters of the matching module based on different impedance devices of different matching branches. For example: Figure 3 As shown in the figure, the first matching sub-module 20 can include a third switching switch 21 and at least two matching branches 22, and different matching branches 22 have different electrical parameters. The first end of the third switching switch 21 is electrically connected with the first segment DE, and the second end of the third switching switch 21 can be electrically connected with at least one of the at least two matching branches 22. In this way, the electrical parameters of the first matching sub-module 20 can be adjusted by adjusting the matching branch 22 conducted by the third switching switch 21.

[0061] It should be noted that, since the second radiator DF includes two segments with inconsistent extension directions, when the current strong points on the second radiator DF are located on the first segment DE and the second segment EF, the current traveling wave directions on the second radiator DF are different, so that the radiation direction of the second radiator DF can be changed by changing the current traveling wave direction on the second radiator DF. The first radiator AC and the second radiator DF form a binary antenna array, and the directional diagram of the binary antenna array is determined by the distance between the current strong points on the first radiator AC and the second radiator DF, the current amplitudes on the first radiator AC and the second radiator DF, and the current phase difference on the first radiator AC and the second radiator DF.

[0062] The current strong point on the first radiator AC represents a position where the current on the first radiator AC is the largest, and the current strong point on the second radiator DF represents a position where the current on the second radiator DF is the largest. The interval between the current strong point on the first radiator AC and the current strong point on the second radiator DF can also be referred to as the phase center interval between the first radiator AC and the second radiator DF.

[0063] In some embodiments, the angle between the extension directions of the first segment DE and the second segment EF can be any angle between 0° and 180°, and the angle between the extension directions of the first segment DE and the second segment EF is not opposite. In this way, the current on the second segment EF can be divided into a component perpendicular to the first segment DE. For ease of illustration, the first segment DE and the second segment EF are generally perpendicular in the embodiments of the present application, which is not a specific limitation.

[0064] In the embodiments of the present application, by adjusting the electrical parameters of the first matching module, at least one of the position of the current strongest point on the second radiator DF, the current amplitude, and the current phase can be changed. Therefore, by adjusting the electrical parameters of the first matching module, the radiation direction of the antenna module can be changed. In this way, when the antenna module is used as a satellite antenna, even if the orientation angle of the antenna module slightly shakes during satellite searching and connection, the radiation direction of the antenna module can be adjusted to be close to the direction of the satellite by adjusting the electrical parameters of the first matching module, so as to smoothly perform satellite searching and connection.

[0065] For ease of illustration, the first matching module includes the first matching sub-module 20 in the following embodiments of the present application.

[0066] As an optional embodiment, as shown in Figure 4 The first matching module includes the first matching sub-module 20, which is electrically connected to the first part 40. The first part 40 is located between the first end D of the first segment DE and the second end E of the first segment DE.

[0067] The first matching sub-module 20 is used to adjust the impedance state of the second radiator DF.

[0068] It is worth mentioning that when the impedance state of the second radiator DF changes, the position of the current strongest point on the second radiator DF can also change.

[0069] In one case, as shown in Figure 5a and Figure 6a When the current strong point on the second radiator DF is located at the second end F of the second segment EF, the second radiator DF includes a first direction (i.e. Figure 5acurrent along the second direction (i.e. the X-axis direction) and a current along the third direction (i.e. the Z-axis direction). Figure 5a current along the second direction (i.e. the X-axis direction) and a current along the third direction (i.e. the Z-axis direction).

[0070] For example, when the electrical parameter of the first matching sub-module 20 is low impedance, such as a large capacitance, a small inductance, a 0-ohm resistor or an equivalent low-impedance circuit composed of a complex circuit, the working mode of the second radiator DF is a 1 / 4 wavelength mode from the first discontinuity 30 to the ground point (i.e. the second end F of the second section EF) of the second radiator DF. The current strong point on the first radiator AC is located at the center B of the first radiator AC, and the current strong point on the second radiator DF is located at the ground point of the second radiator DF. At this time, the current on the second radiator DF has a component along the Z-axis direction and a component along the X-axis direction.

[0071] In another case, as shown in Figure 5b and Figure 6b When the current strong point on the second radiator DF is located on the first section DE, the second radiator DF only includes a current along the X-axis direction.

[0072] For example, when the electrical parameter of the first matching sub-module 20 is high impedance, such as a small capacitance, a large inductance, an open circuit or an equivalent high-impedance circuit composed of a complex circuit, the working mode of the second radiator DF is a 1 / 4 wavelength mode from the first discontinuity 30 to the first part 40. The current strong point on the first radiator AC is located at the center B of the first radiator AC, and the current strong point on the second radiator DF is located at the first part 40 of the second radiator DF. At this time, the current of the second radiator DF only has a component along the X-axis direction.

[0073] In this embodiment, the first radiator AC is coupled to the second radiator DF through the first discontinuity 30, and the first matching sub-module 20 is electrically connected to the first part 40 on the first section DE. In this way, the current phase of the second radiator DF based on the coupling does not change, and by adjusting the electrical parameter of the first matching sub-module 20, the current amplitude on the second radiator DF and the position of the current strong point can be changed, and by adjusting whether the current on the second radiator DF has a component along the Z-axis direction, the adjustment of the directional diagram of the antenna module in the Y-axis direction can be realized.

[0074] It should be noted that the directional diagram of the antenna module can also be affected by other structures, so that the best radiation direction of the antenna module is towards the +Z-axis direction, or towards the +Z-axis and +Y-axis direction, or towards the +Z-axis and -Y-axis direction, etc.

[0075] For example, as shown in Figure 6a and Figure 6b The antenna module further comprises a metal plate 50.

[0076] The metal plate 50 is grounded and is located on one side of the first radiator AC and the second radiator DF, and has a gap 51 between the metal plate 50 and the first radiator AC and the second radiator DF;

[0077] The thickness of the metal plate 50 along the third direction is less than the thickness of the first radiator AC and the second radiator DF along the third direction, and the third direction is perpendicular to the first radiator AC, the first segment DE, and the second segment EF.

[0078] The third direction represents the Y-axis direction in Figure 6a and Figure 6b , and Figure 5a , 5b , Figure 6a and Figure 6b , the arrow line on the radiator is used to represent the current direction on the first radiator AC and the second radiator DF, and the dot on the radiator represents the current strong point on the first radiator AC and the second radiator DF.

[0079] As shown in Figure 6a , when the current strong point on the second radiator DF is located at the second end F of the second segment EF, the second radiator DF includes the current along the X-axis direction and the current along the Z-axis direction, and because the first radiator AC and the second radiator DF are thicker than the metal plate 50 in the Y-axis direction, the current density on the first radiator AC and the second radiator DF is less than the current density on the metal plate 50, so the left-handed component is mainly contributed by the metal plate 50, and the flow direction of the current on the metal plate 50 is from the first end A of the first radiator AC to the second end F of the second radiator DF, according to the left-hand contrast, it can be deduced that the radiation direction of the left-handed circular polarization will be biased to the +Y direction, therefore, the actual optimal radiation direction of the antenna module is the direction towards the +Z axis and biased to the +Y axis.

[0080] As shown in Figure 6b , when the current strong point on the second radiator DF is located on the first segment DE, the second radiator DF only includes the current along the X-axis direction, and the electric field energy is mainly concentrated in the gap 51, because the first radiator AC and the second radiator DF are thicker than the metal plate 50 in the Y-axis direction, the current density on the first radiator AC and the second radiator DF is less than the current density on the metal plate 50, and the flow direction of the current on the metal plate 50 and the radiator at this time is straight, from the first end A of the first radiator AC to the second end E of the first segment DE, the left-handed and right-handed components are equivalent, and the radiation direction of the left-handed component mainly depends on the overall maximum radiation direction, due to the reflection effect of 50, the overall radiation direction will be biased to the -Y axis direction, therefore, the actual optimal radiation direction of the antenna module is the direction towards the +Z axis and biased to the -Y axis.

[0081] In some embodiments, asFigure 4 As shown, the antenna module further comprises a second matching module 60;

[0082] The second matching module 60 is connected in series between the first feeding port 10 and the first end A of the first radiator AC, and the electrical parameter of the second matching module 60 is adjustable, which includes at least one of capacitance, inductance and resistance;

[0083] In the first working mode, the electrical parameter of the second matching module 60 is adjusted by the first switching switch 61, so that the impedance matching function corresponding to the working frequency band of the electrical signal transmitted through the first feeding port 10 can be realized.

[0084] In this embodiment, the second matching module 60 is used to realize the impedance matching function corresponding to the working frequency band of the electrical signal transmitted through the first feeding port 10, for example, when the working frequency band of the electrical signal transmitted through the first feeding port 10 is switched, such as between the uplink satellite communication frequency band or the downlink satellite communication frequency band, the impedance matching function of the antenna module can be realized by the second matching module 60. The first matching sub-module 20 can adjust the current strong point position on the second radiator DF to adjust the radiation direction on the second radiator DF, and finally combine with the radiation direction on the first radiator AC to determine the radiation direction of the entire antenna module.

[0085] In some embodiments, in the first working mode, the current traveling wave component on the first radiator AC propagates along the first direction (X-axis); the first matching sub-module 20 includes a first impedance state and a second impedance state, and the impedance value in the first impedance state is greater than the impedance value in the second impedance state;

[0086] In the case where the first matching sub-module 20 is in the first impedance state, the current traveling wave component on the second radiator DF propagates along the first direction (X-axis), and the radiation direction of the antenna module is along the first direction (X-axis);

[0087] In the case where the first matching sub-module 20 is in the second impedance state, the current traveling wave component on the second radiator DF includes components propagating along the first direction (X-axis) and the second direction (Z-axis), and the radiation direction of the antenna module is along the second direction (Z-axis) and deviates to the first direction (X-axis);

[0088] Wherein, the first direction (X-axis) is the extension direction of the first radiator AC, and the second direction (Z-axis) is the extension direction along the second segment.

[0089] In some embodiments, the first impedance state can be a high impedance state, and the second impedance state can be a low impedance state.

[0090] For example, when the electrical parameter of the first matching sub-module 20 is low impedance, such as connecting a large capacitor, a small inductor, a 0-ohm resistor or an equivalent low impedance circuit composed of complex circuits, the working mode of the second radiator DF is the 1 / 4 wavelength mode from the first discontinuity 30 to the ground point (i.e. the second end F of the second segment EF) of the second radiator DF. The current strong point on the first radiator AC is located at the center B of the first radiator AC, and the current strong point on the second radiator DF is located at the ground point of the second radiator DF. At this time, the current on the second radiator DF has a component in the Z-axis direction and a component in the X-axis direction.

[0091] When the electrical parameter of the first matching sub-module 20 is high impedance, such as connecting a small capacitor, a large inductor, an open circuit or an equivalent high impedance circuit composed of complex circuits, the working mode of the second radiator DF is the 1 / 4 wavelength mode from the first discontinuity 30 to the first part 40. The current strong point on the first radiator AC is located at the center B of the first radiator AC, and the current strong point on the second radiator DF is located at the first part 40 of the second radiator DF. At this time, the current of the second radiator DF only has a component in the X-axis direction.

[0092] For ease of illustration, the second antenna module as shown in Figure 4 is taken as an example to simulate the directional diagram of the antenna module. In the simulation process, it is assumed that the antenna module is arranged at the top end of a mobile phone, and the back view of the mobile phone is as shown in Figure 7 , i.e. the long side direction of the mobile phone is the Z-axis direction, the short side direction is the X-axis direction, and the thickness direction is the Y-axis direction, as shown in Figure 7 , Theta is the angle with the +Z-axis, and Phi is the angle with the +X-axis in the XOY plane.

[0093] For ease of comparison, two matching conditions are set, as shown in Figure 9a , which is the first matching condition, the electrical parameter of the first matching sub-module 20 is a 1pF capacitor, i.e. the first matching sub-module 20 is equivalent to electrically connecting a 1pF capacitor with the first part 40; as shown in Figure 9b , which is the second matching condition, the electrical parameter of the first matching sub-module 20 can be a 0.3pF capacitor, i.e. the first matching sub-module 20 is equivalent to electrically connecting a 0.3pF capacitor with the first part 40.

[0094] As shown in Figure 8a , which is the left-handed circular polarization gain directional diagram of the antenna module in the above first matching condition, Figure 8a the colored area in the figure represents the area with a gain greater than 0dB; as can be seen from Figure 8a , the radiation energy of the antenna module is mainly concentrated in the area near Theta=20°, Phi=270°.

[0095] As shown in Figure 8b , the colored area in the left-hand circular polarized gain pattern of the antenna module in the second matching case, Figure 8b represents the area with gain greater than 0dB; it can be seen from Figure 8a that the radiation energy of the antenna module is mainly concentrated in the area near Theta=20°, Phi=90°.

[0096] Optionally, when the second matching module 60 exists, the electrical parameters of the second matching module 60 in the first matching case and the second matching case are different from each other. The second matching module 60 is a general circuit for impedance matching, and the specific topology is not described here.

[0097] By comparing Figure 8a and Figure 8b , it can be seen that by adjusting the electrical parameters of the first matching sub-module 20, the left-hand circular polarized gain pattern of the antenna module can be changed.

[0098] As an optional implementation, as shown in Figure 4 , the antenna module provided by the embodiment of the application further includes a first switching switch 61, a second feeding port 70 and a second switching switch 81.

[0099] As shown in Figure 9c , the first feeding port 10 is electrically connected with the first end A of the first radiator AC through the first switching switch 61.

[0100] As shown in Figure 9d , the second feeding port 70 is electrically connected with the second part 82 through the second switching switch 81, and the second part 82 is a part of the first radiator AC except the first end A.

[0101] The antenna module includes a first working mode and a second working mode.

[0102] In the first working mode, the first switching switch 61 electrically connects the first feeding port 10 with the first end A of the first radiator AC, and the second switching switch 81 disconnects the second feeding port 70 from the second part 82.

[0103] In the second working mode, the first switching switch 61 disconnects the first feeding port 10 from the first end of the first radiator AC, and the second switching switch 81 electrically connects the second feeding port 70 with the second part 82.

[0104] In some embodiments, the second feeding port 70 can be a feeding port of any frequency band, and in the embodiments of the present application, the second feeding port 70 is usually taken as an example of a feeding port of a cellular communication frequency band. At this time, the second feeding port 70 can utilize the first radiator AC to realize signal radiation of the cellular communication frequency band, and the first feeding port can reuse the first radiator AC to realize signal radiation of the satellite communication frequency band.

[0105] In some embodiments, the first working state can be understood as a working mode in which the first feeding port 10 feeds the first radiator AC, and the second feeding port 70 does not feed the first radiator AC in the satellite communication mode.

[0106] For example, when the satellite function is turned on to enter the satellite communication mode, the second switch 81 is open-circuited, and the first matching sub-module 20 and the second matching module 60 jointly realize antenna matching adjustment. The antenna structure and circuit topology at this time are simplified as shown in Figure 5a .

[0107] In some embodiments, the second working state can be understood as a working mode in which the second feeding port 70 feeds the first radiator AC, and the first feeding port 10 does not feed the first radiator AC in the cellular communication mode. The antenna structure and circuit topology at this time are simplified as shown in Figure 5b .

[0108] For example, when the satellite function is turned off to enter the cellular mode, the first switch 61 can short the first end of the first radiator AC to the ground, and the first feeding port 10 no longer feeds, but feeds through the second feeding port 70.

[0109] In some embodiments, as shown in Figure 4 and Figure 10 , the antenna module further comprises a third matching module 80.

[0110] The third matching module 80 is connected in series between the second feeding port 70 and the second part 82, and the second switch 81 is a switch in the third matching module 80.

[0111] The electrical parameter of the third matching module 80 is adjustable, and the electrical parameter includes at least one of capacitance, inductance and resistance.

[0112] In the second working mode, the electrical parameter of the third matching module 80 is adjusted through the second switch 81, so that the impedance matching function corresponding to the working frequency band of the electrical signal transmitted through the second feeding port 70 can be realized.

[0113] As shown in Figure 4 , Figure 9c and Figure 9dAs shown in FIG. 1, in some embodiments of the present application, the second matching module 60 is generally multiplexed with the switching switch in the first matching sub-module 20 by the first switching switch 61, and the third matching module is multiplexed with the switching switch by the second switching switch 81. However, in other embodiments, the first switching switch 61 and the second switching switch 81 can be independent switching switches, which are not limited herein.

[0114] In some embodiments, as shown in FIG. 2, the second matching module 60 has a structure and working principle similar to the first matching sub-module 20 described above, for example, the first switching switch 61 and at least two matching branches 62, which are not repeated here. Figure 9c

[0115] In some embodiments, as shown in FIG. 3, the third matching module 80 has a structure and working principle similar to the first matching sub-module 20 described above, for example, the second switching switch 81 and at least two matching branches 83, which are not repeated here. Figure 9d

[0116] In the present embodiment, by setting the third matching module 80 with adjustable electrical parameters between the second feeding port 70 and the second part 82, the impedance matching function of the working frequency band of the electrical signal transmitted through the second feeding port 70 can be realized.

[0117] For example, when feeding through the second feeding port 70, the first matching sub-module 20 and the third matching module 80 can be used to realize the switching of the cellular frequency band. For example, the first radiator AC mainly works in the low frequency band (Low Band, LB), and the third matching module 80 is used to realize the switching of the Band5 / Band8 / Band28 frequency band.

[0118] In addition, when the first matching sub-module 20 is connected in series between the second radiator DF and other feeding ports, the other feeding ports can feed the second radiator DF to make the second radiator DF mainly work in the middle high frequency band (Middle High Band, MHB), and the first matching sub-module 20 is used to realize the switching of the Band1 / Band3 / Band40 / Band41 frequency band.

[0119] In the present embodiment, the LB and MHB antennas can be multiplexed to be compatible with satellite communication, thereby avoiding occupying the layout space of the cellular communication antenna due to the additional setting of the satellite communication antenna.

[0120] As an optional embodiment, as shown in FIG. 4, the antenna module provided by the embodiment of the present application further comprises a fourth matching module 90. Figure 11

[0121] ​​​The first end of the fourth matching module 90 is grounded, and the second end of the fourth matching module 90 is electrically connected to the third part 91, which is located in the middle region of the first radiator AC.

[0122] The electrical parameters of the fourth matching module 90 are adjustable, and the electrical parameters include at least one of capacitance, inductance and resistance;

[0123] In the first working mode, the electrical parameters of the fourth matching module 90 are adjusted to ground the third part 91.

[0124] In the second operating mode, by adjusting the electrical parameters of the fourth matching module 90, impedance matching function corresponding to the operating frequency band of the electrical signal transmitted through the second power supply port 70 can be achieved.

[0125] In some implementations, the fourth matching module 90 has a similar structure and working principle to the first matching submodule 20 described above in this application. For example, it may be a switching switch and at least two matching branches, which will not be elaborated here.

[0126] In the first operating mode, when the third part 91 is grounded, the half-wave mode of the first radiator AC is more stable and less affected by the second radiator DF, making it more convenient to adjust the antenna module pattern.

[0127] For example: Figure 12 As shown, in satellite communication mode, the first feed port 10 feeds power to the first end of the first radiator AC, the second matching module 60 is used to achieve impedance matching of the first radiator AC, the fourth matching module 90 is used to ground the third part 91, the third matching module 80 is used to disconnect the second feed port 70 from the second part 82, and the first matching submodule 20 is used for matching adjustment to adjust the coupling current on the second radiator DF.

[0128] In the second operating mode, the second power supply port 70 supplies power to the second part 82 of the first radiator AC. By adjusting the electrical parameters of the fourth matching module 90, impedance matching function corresponding to the operating frequency band of the electrical signal transmitted through the second power supply port 70 can be achieved.

[0129] For example: Figure 13As shown, the first end A of the first radiator AC is grounded by the second matching module 60, the second feeding port 70 feeds the second part 82 through the third matching module 80, and the fourth matching module 90, the first matching submodule 20 and the third matching module 80 are matched and adjusted. Similar to the previous embodiment, the first radiator AC can work in LB, and the second radiator DF can work in MHB. Because the fourth matching module 90 is newly added for matching adjustment, the matching adjustment is more flexible, which is conducive to the performance debugging and improvement of LB and MHB.

[0130] As an optional embodiment, as shown in Figure 14 As shown, the first matching module includes a second matching submodule 110, the first end of the second matching submodule 110 is electrically connected to the second end C of the first radiator AC, and the second end of the second matching submodule 110 is electrically connected to the first end D of the first segment DE.

[0131] The second matching submodule 110 is used to adjust at least one of the current phase and the current amplitude on the second radiator DF.

[0132] In this embodiment, the second matching submodule 110 is arranged at the first break 30. In this way, by adjusting the electrical parameter such as the capacitance value or the inductance value of the second matching submodule 110, the coupling degree between the first radiator AC and the second radiator DF can be adjusted, so as to change the phase and amplitude of the current on the second radiator DF, and the adjustment of the directional diagram along the X-axis direction can be realized.

[0133] In some embodiments, the adjustable electrical parameter of the second matching submodule 110 connected in series between the second end C of the first radiator AC and the first end D of the first segment DE can be at least one of the capacitance value and the inductance value. By adjusting at least one of the capacitance value and the inductance value of the second matching submodule 110, the amplitude and phase of the coupled current on the second radiator DF can be changed, and the deviation degree of the directional diagram of the antenna module along the X direction is adjusted.

[0134] For example, as shown in Figure 16a As shown, assuming that the impedance value of the second matching submodule 110 connected in series between the second end C of the first radiator AC and the first end D of the first segment DE is Z0, at this time, the current strong point on the second radiator DF is located on the first segment DE, and the phase of the current strong point on the first radiator AC is the same as that of the current strong point on the second radiator DF, and the best radiation direction of the antenna module is towards the +Z-axis direction.

[0135] As shown in Figure 16bAs shown in FIG. 6, assuming that the impedance value of the second matching sub-module 110 connected in series between the second end C of the first radiator AC and the first end D of the first section DE is Z0+L, where L is an inductance value, the current strong point on the second radiator DF is located on the first section DE, and the phase of the current strong point on the first radiator AC lags behind the phase of the current strong point on the second radiator DF, the optimal radiation direction of the antenna module is towards the +Z axis and deviates towards the +X axis direction.

[0136] As shown in FIG. 6, assuming that the impedance value of the second matching sub-module 110 connected in series between the second end C of the first radiator AC and the first end D of the first section DE is Z0+L, where L is an inductance value, the current strong point on the second radiator DF is located on the first section DE, and the phase of the current strong point on the first radiator AC lags behind the phase of the current strong point on the second radiator DF, the optimal radiation direction of the antenna module is towards the +Z axis and deviates towards the +X axis direction. Figure 16c As shown in FIG. 6, assuming that the impedance value of the second matching sub-module 110 connected in series between the second end C of the first radiator AC and the first end D of the first section DE is Z0+L, where L is an inductance value, the current strong point on the second radiator DF is located on the first section DE, and the phase of the current strong point on the first radiator AC lags behind the phase of the current strong point on the second radiator DF, the optimal radiation direction of the antenna module is towards the +Z axis and deviates towards the +X axis direction.

[0137] Figure 16a to Figure 16c As shown in FIG. 6, assuming that the impedance value of the second matching sub-module 110 connected in series between the second end C of the first radiator AC and the first end D of the first section DE is Z0+L, where L is an inductance value, the current strong point on the second radiator DF is located on the first section DE, and the phase of the current strong point on the first radiator AC lags behind the phase of the current strong point on the second radiator DF, the optimal radiation direction of the antenna module is towards the +Z axis and deviates towards the +X axis direction.

[0138] It should be noted that the working principle of the satellite communication mode in the embodiment is similar to that in the foregoing embodiment, the first radiator AC is a main branch and works in a half-wave mode, and the second radiator DF is a coupling branch and works in a 1 / 4 mode. The antenna pattern is switched by adjusting the electrical parameters of the second matching sub-module 110 and the second matching module 60. The second matching sub-module 110 is specifically configured to adjust the coupling current on the second radiator DF, and the second matching module 60 is configured to adjust the impedance matching of the first radiator AC.

[0139] The embodiment can realize the adjustment of the pattern of the antenna module along the X axis direction by using the second matching sub-module 110 connected in series between the second end C of the first radiator AC and the first end D of the first section DE.

[0140] In some embodiments, as shown in FIG. 6, the second matching sub-module 110 is connected in series between the second end C of the first radiator AC and the first end D of the first section DE. Figure 14 ​As shown, the first matching module can include a first matching submodule 20 and a second matching submodule 110, wherein the second matching submodule 110 is connected in series between the second end C of the first radiator AC and the first end D of the first section DE, and the first matching submodule 20 is electrically connected to the first part 40 of the first section DE, at this time, the second matching submodule 110 connected in series between the second end C of the first radiator AC and the first end D of the first section DE can change the coupling degree between the first radiator AC and the second radiator DF, control the phase and amplitude of the current on the second radiator DF; the first matching submodule 20 electrically connected to the first part 40 of the first section DE can change the position of the current strong point on the second radiator DF, thereby controlling the spacing between the current strong point on the first radiator AC and the current strong point on the second radiator DF, and the directivity pattern of the antenna module can be more flexibly adjusted.

[0141] For example, as shown in FIG. 1, in the satellite communication mode, the first feed port 10 feeds the first radiator AC, the second matching module 60 is matched and adjusted, the third matching module 80 is used to disconnect the second feed port 70 from the second part 82, the second matching submodule 110 connected in series between the second end C of the first radiator AC and the first end D of the first section DE is used to adjust the coupling degree between the first radiator AC and the second radiator DF, and the first matching submodule 20 electrically connected to the first part 40 of the first section DE is used for matching adjustment. Figure 15 As shown in FIG. 1, in the satellite communication mode, the first feed port 10 feeds the first radiator AC, the second matching module 60 is matched and adjusted, the third matching module 80 is used to disconnect the second feed port 70 from the second part 82, the second matching submodule 110 connected in series between the second end C of the first radiator AC and the first end D of the first section DE is used to adjust the coupling degree between the first radiator AC and the second radiator DF, and the first matching submodule 20 electrically connected to the first part 40 of the first section DE is used for matching adjustment.

[0142] In this embodiment, the first matching submodule 20 electrically connected to the first part 40 of the first section DE has the same function as the first matching submodule 20 in the foregoing embodiment, which is to adjust the deviation of the directivity pattern of the antenna module along the Y direction.

[0143] It is worth mentioning that, as shown in FIG. 1, in the satellite communication mode, the first feed port 10 feeds the first radiator AC, the second matching module 60 is matched and adjusted, the third matching module 80 is used to disconnect the second feed port 70 from the second part 82, the second matching submodule 110 connected in series between the second end C of the first radiator AC and the first end D of the first section DE is used to adjust the coupling degree between the first radiator AC and the second radiator DF, and the first matching submodule 20 electrically connected to the first part 40 of the first section DE is used for matching adjustment. Figure 17 As shown in FIG. 1, in the satellite communication mode, the first feed port 10 feeds the first radiator AC, the second matching module 60 is matched and adjusted, the third matching module 80 is used to disconnect the second feed port 70 from the second part 82, the second matching submodule 110 connected in series between the second end C of the first radiator AC and the first end D of the first section DE is used to adjust the coupling degree between the first radiator AC and the second radiator DF, and the first matching submodule 20 electrically connected to the first part 40 of the first section DE is used for matching adjustment.

[0144] As a feasible embodiment, as shown in FIG. 1, the antenna module provided by the embodiment of the application further includes a third radiator HJ and a fifth matching module 100. Figure 18

[0145] ​The third radiator HJ includes a third segment HI and a fourth segment IJ extending perpendicularly to each other, the third segment HI extends in the same direction as the second segment EF, and the fourth segment IJ extends in the same direction as the first radiator AC;

[0146] The first end H of the third segment HI is grounded, the second end I of the third segment HI is electrically connected with the first end I of the fourth segment IJ (i.e., the third segment HI and the fourth segment IJ can be an integral structure), and the second end J of the fourth segment IJ is between the first end A of the first radiator AC and the second end J of the fourth segment IJ.

[0147] The fifth matching module 100 is electrically connected with the fourth part 102, and the fourth part 102 is between the first end I of the fourth segment IJ and the second end J of the fourth segment IJ.

[0148] The electrical parameter of the fifth matching module 100 is adjustable, and the electrical parameter includes at least one of capacitance, inductance and resistance.

[0149] The fifth matching module 100 is used to adjust at least one of the position of the strongest current point, the current amplitude and the current phase on the third radiator HJ, so as to adjust the radiation direction of the antenna module.

[0150] In some embodiments, the fifth matching module 100 is similar to the first matching module in structure and working principle, for example, it can be a switching switch and at least two matching branches, which will not be described here.

[0151] In addition, similar to the first matching module, the fifth matching module 100 can also include a matching sub-module connected in series between the opposite two side walls of the second gap 101, and the working principle and function of the matching sub-module are similar to those of the second matching sub-module 110, which will not be described here.

[0152] It should be noted that the third radiator HJ and the second radiator DF are distributed at opposite ends of the first radiator AC, at this time, the third radiator HJ cooperates with the fifth matching module 100 to assist in adjusting the principle of the antenna module pattern, and the second radiator DF cooperates with the first matching module to assist in adjusting the principle of the antenna module pattern, which is the same as the principle of the antenna module pattern, which will not be described here.

[0153] The difference between the present embodiment and the aforementioned embodiment including only the second radiator DF includes that the first radiator AC has two parasitic radiators, wherein the third radiator HJ is located on the left side of the first radiator AC, and the second radiator DF is located on the right side of the first radiator AC.

[0154] In this embodiment, the third radiator HJ and the second radiator DF can be used to assist in adjusting the directional diagram of the antenna module. Compared with the mode of assisting in adjusting the directional diagram of the antenna module by only the second radiator DF, the degree and flexibility of adjusting the directional diagram can be improved.

[0155] In some embodiments, for the first matching sub-module 20 electrically connected to the first part 40 on the second radiator DF, and / or the fifth matching module 100 electrically connected to the fourth part 102 on the third radiator HJ, the other feed port can be electrically connected. In this way, in the non-satellite communication mode, the second radiator DF and / or the third radiator HJ can be fed by using the other feed port to realize the communication mode of multiple frequency bands.

[0156] The application also provides an electronic device, which comprises any one of the antenna modules provided in the foregoing embodiments of the application.

[0157] In the embodiments of the application, by arranging the antenna module of the embodiments of the application on the electronic device, the electronic device can dynamically adjust the radiation direction of the antenna module according to the relative position relationship between the electronic device and the satellite during the process of satellite searching or establishing a satellite communication connection, so that the radiation direction of the antenna module is directed to or close to the direction in which the satellite is located. In this way, even if the orientation angle of the antenna module slightly shakes during the satellite searching and connection process, the electrical parameters of the first matching module can be adjusted to make the radiation direction of the antenna module close to the direction in which the satellite is located, so that the satellite searching and connection can be successfully performed.

[0158] It should be noted that the electronic device provided in the embodiments of the application can be a terminal or other devices other than the terminal. For example, the electronic device can be a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted electronic device, a mobile Internet device (MID), an augmented reality (AR) / virtual reality (VR) device, a robot, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA), etc. The electronic device can also be a server, a network attached storage (NAS), a personal computer (PC), a television (TV), a teller machine, or a self-service machine, etc. The embodiments of the application are not limited in this regard.

[0159] In some embodiments, the electronic device provided by the embodiments of the present application further comprises a display screen.

[0160] The display screen has a metal plate grounded, the display screen is located on one side of the first radiator and the second radiator, and the metal plate has a gap between the first radiator and the second radiator.

[0161] The thickness of the metal plate along a third direction is less than the thickness of the first radiator and the second radiator along the third direction, and the third direction is perpendicular to the first radiator, the first segment and the second segment.

[0162] The metal plate can affect the radiation signals of the first radiator AC and the second radiator DF to change the radiation direction of the antenna module.

[0163] For example, as shown in Figure 6a When the strong current point on the second radiator DF is located at the second end F of the second segment EF, and the second radiator DF includes current along the X-axis direction and current along the Z-axis direction, the radiation signal of the antenna module is affected by the reflection of the metal plate 50, which makes the optimal radiation direction of the antenna module deviate towards the -Y-axis direction, and therefore, the actual optimal radiation direction of the antenna module is towards the +Z-axis and deviates towards the -Y-axis direction.

[0164] As shown in Figure 6b When the strong current point on the second radiator DF is located on the first segment DE, and the second radiator DF only includes current along the X-axis direction, the electric field energy is mainly concentrated in the gap 51, and since the first radiator AC and the second radiator DF are thicker than the metal plate 50 in the Y-axis direction, the current density on the first radiator AC and the second radiator DF is less than the current density on the metal plate 50, which makes the optimal radiation direction of the antenna module deviate towards the -Y-axis direction, and therefore, the actual optimal radiation direction of the antenna module is towards the +Z-axis and deviates towards the -Y-axis direction.

[0165] In this embodiment, the metal plate grounded in the display screen can be reused to affect the radiation direction of the antenna module.

[0166] Referring to Figure 19 The embodiments of the present application also provide an antenna parameter adjustment method, which is applied to the electronic device provided by the previous embodiment of the present application, as shown in Figure 19 The antenna parameter adjustment method comprises the following steps:

[0167] Step 1901, in the process of establishing a satellite communication connection, the spatial posture information of the electronic device is acquired.

[0168] In some embodiments, the sensing data of sensors such as a gyroscope and an electronic compass inside the electronic device can be called to calculate the spatial posture information of the electronic device.

[0169] In some embodiments, the spatial posture information of the electronic device can be represented as the orientation information of the top end of the electronic device, such as the spatial posture information of the electronic device containing the included angle between the long side of the electronic device and the ground plane, and the orientation information of the front or back of the electronic device.

[0170] Step 1902, determining the current radiation direction of the antenna module according to the spatial posture information.

[0171] In some embodiments, before adjusting the radiation direction of the antenna module, the electrical parameters of the first matching module are fixed, and the radiation direction of the antenna module is also fixed. The current radiation direction of the antenna module, i.e., the current optimal radiation direction of the antenna module, can be determined based on the correlation between the optimal radiation direction of the antenna module and the spatial posture information of the electronic device.

[0172] Step 1903, adjusting the electrical parameters of the first matching module according to the difference between the current radiation direction of the antenna module and a target direction, so as to reduce the difference between the radiation direction of the antenna module and the target direction, wherein the target direction is the direction of the satellite.

[0173] In some embodiments, after determining the current optimal radiation direction of the antenna module, there can be a case that the current optimal radiation direction of the antenna module is not oriented to the direction of the satellite. At this time, the electrical parameters of the first matching module are adjusted according to the difference between the current radiation direction of the antenna module and the target direction, so as to reduce the difference between the radiation direction of the antenna module and the target direction, which can improve the probability of the radiation direction of the antenna module being oriented to the direction of the satellite, thereby improving the communication reliability between the antenna module and the satellite.

[0174] It should be noted that, taking the electronic device as a mobile phone as an example, the mobile phone needs to continue for a certain period of time in the process of satellite searching or establishing satellite communication connection. During the period of time, the user holds the mobile phone so that the best radiation direction of the mobile phone remains in the direction of the satellite, and the satellite searching or satellite communication connection can be successfully completed. During the process, the user's hand can shake, that is, the spatial posture information of the electronic device is dynamically changing. At this time, the spatial posture information of the electronic device needs to be dynamically acquired, and the current best radiation direction of the antenna module is periodically or actually acquired, and the electrical parameters of the first matching module are adjusted to reduce the difference between the radiation direction of the antenna module and the target direction. In this way, during the satellite searching or connection process, the difference angle between the radiation direction of the antenna module and the direction of the satellite caused by the change of the user's holding posture of the mobile phone can be compensated by dynamically adjusting the radiation direction of the antenna module, so that the radiation direction of the antenna module always remains aligned with the direction of the satellite or reduces the difference between the radiation direction of the antenna module and the direction of the satellite. Therefore, even if the orientation angle of the antenna module slightly shakes, the satellite searching and connection can be successfully performed by adjusting the radiation direction of the antenna module.

[0175] As an optional implementation, the method further comprises:

[0176] According to the difference between the current radiation direction of the antenna module and the target direction, adjusting the electrical parameters of at least one of the second matching module, the fourth matching module and the fifth matching module to reduce the difference between the radiation direction of the antenna module and the target direction in combination with the electrical parameters of the first matching module.

[0177] Among them, the second matching module, the fourth matching module and the fifth matching module have the same structure, function and working principle as the second matching module, the fourth matching module and the fifth matching module in the aforementioned antenna module embodiments of the application, and will not be repeated here.

[0178] As an optional implementation, the method further comprises:

[0179] Acquiring the maximum adjustment value of the radiation direction of the antenna module by adjusting the electrical parameters of the first matching module and at least one of the second matching module, the fourth matching module and the fifth matching module;

[0180] In a case where the maximum adjustment value is greater than or equal to the difference between the current radiation direction of the antenna module and the target direction, the electrical parameters of at least one of the first matching module and the second matching module, the fourth matching module, and the fifth matching module are adjusted to make the radiation direction of the antenna module coincide with the target direction.

[0181] In a case where the maximum adjustment value is less than the difference between the current radiation direction of the antenna module and the target direction, the electrical parameters of at least one of the first matching module and the second matching module, the fourth matching module, and the fifth matching module are adjusted according to the maximum adjustment value, and a prompt information is output, where the prompt information is used to prompt a user to adjust the spatial pose of the electronic device so that the radiation direction of the antenna module coincides with the target direction.

[0182] In some embodiments, when the difference between the current radiation direction of the antenna module and the target direction can be compensated by adjusting the electrical parameters of at least one of the first matching module and the second matching module, the fourth matching module, and the fifth matching module, the electrical parameters of at least one of the first matching module and the second matching module, the fourth matching module, and the fifth matching module can be directly adjusted according to the difference between the current radiation direction of the antenna module and the target direction to make the radiation direction of the antenna module align with the direction of the satellite.

[0183] In other embodiments, when the difference between the current radiation direction of the antenna module and the target direction exceeds the radiation direction adjustment value that can be adjusted by adjusting the electrical parameters of at least one of the first matching module and the second matching module, the fourth matching module, and the fifth matching module, the electrical parameters of at least one of the first matching module and the second matching module, the fourth matching module, and the fifth matching module can be first adjusted according to the maximum radiation direction adjustment value to make the difference between the adjusted radiation direction of the antenna module and the target direction as small as possible. Thereafter, a prompt information can be output to prompt a user to adjust the orientation of the electronic device, and finally make the radiation direction of the antenna module align with the direction of the satellite.

[0184] In the present embodiment, considering the case where the difference between the current radiation direction of the antenna module and the target direction exceeds the radiation direction adjustment value that can be adjusted by adjusting the electrical parameters of at least one of the first matching module and the second matching module, the fourth matching module, and the fifth matching module, at this time, the way of adjusting the radiation direction of the antenna module based on the electrical parameters of at least one of the first matching module and the second matching module, the fourth matching module, and the fifth matching module can be combined with the way of manually adjusting the spatial pose of the electronic device by the user to jointly make the radiation direction of the antenna module align with the direction of the satellite.

[0185] The embodiment of the present application further provides a readable storage medium, wherein the readable storage medium stores programs or instructions, and the programs or instructions are executed by a processor to realize the processes of the antenna parameter adjustment method and achieve the same technical effects.
