[0002] With the rapid development of communication technology, electronic devices such as smartphones are incorporating more and more antenna functions to obtain a better communication experience. Smartphones typically have antennas such as Tiantong satellite antennas, Beidou satellite antennas, and Xingwang satellite antennas. During satellite communication with a smartphone, the angle between the incoming satellite wave and the ground varies depending on the location, requiring constant adjustment of the angle between the smartphone and the ground to ensure communication, resulting in a poor communication experience.

[0042] This disclosure proposes an antenna module equipped with a first variable impedance component. One end of this first variable impedance component is connected to the upper frame point of the radiating stub, and the other end is grounded. This component is used to adjust the current reversal point of the radiating stub. In other words, this disclosure no longer uses capacitors and inductors with fixed impedance values, but instead uses a first variable impedance component whose impedance value can change. The current reversal point of the radiating stub, adjusted by the first variable impedance component, can change the antenna pattern, ensuring that the antenna pattern of the antenna module always adapts to the direction of satellite arrival, thereby achieving optimal signal strength between the antenna module and the satellite. Thus, communication in this disclosure is not geographically limited, and communication quality and user experience can be improved without adjusting the angle of the electronic device with the antenna module.

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

[0058] This disclosure provides an antenna module. This antenna module is applied in satellite communication scenarios. For example, when the antenna module transmits and receives satellite communication signals, the antenna module of this disclosure can be used to adjust the impedance of the first variable impedance component to reconstruct the antenna pattern of the antenna module, thereby enabling communication to be unrestricted by geographical location and improving communication quality.

[0059] Figure 1 This is a schematic diagram illustrating the structure of an antenna module according to an exemplary embodiment. For example... Figure 1 As shown, the antenna module includes:

[0060] Radiating branches 100;

[0061] Feed point 101 is provided at the radiating stub 100 and can feed a signal to the radiating stub 100 to make the radiating stub work;

[0062] The upper frame point 102 and the feed point 101 are located at different positions in the radiating branch 100;

[0063] The first variable impedance component 103 is connected at one end to the upper frame point 102 and at the other end to ground, and is used to adjust the current reverse point of the radiating branch.

[0064] In this embodiment of the disclosure, the antenna module is applied in an electronic device for transmitting and receiving radio waves to transmit and exchange wireless signals. The electronic device includes: smartphones, tablets, laptops, wearable devices, or personal digital assistants (PDAs), etc. Wearable devices include, but are not limited to, smartwatches or smart bracelets.

[0065] In some embodiments, the antenna module is used to transmit and receive satellite communication signals.

[0066] Here, the satellite communication signals transmitted and received by the antenna module can be used for satellite positioning, satellite communication, and terrestrial mobile communication. The frequency bands of these satellite communication signals can include the S-band and C-band. The S-band has a frequency range of 2 to 4 GHz, while the C-band is located between 4 and 8 GHz.

[0067] The aforementioned radiating branches can be formed by reusing the frame of an electronic device, or they can be made of a flexible circuit board; the embodiments disclosed herein are not limited to these.

[0068] The shape and size of the aforementioned radiating branches can be set according to actual needs, and this disclosure does not impose any limitations on them. For example, the shape of the radiating branches can be set to a strip shape or an arc shape. As another example, the size of the radiating branches can be set according to the size of the electronic device; for example, the length of the radiating branches can be set to be less than the width of the electronic device.

[0069] In some embodiments, such as Figure 1 As shown, the radial branches 100 are strip-shaped, and the length of the radial branches 100 is between 27 mm and 33 mm.

[0070] It should be noted that the length of the radiating stub is negatively correlated with the frequency band in which it operates; that is, the higher the center frequency of the operating frequency band, the shorter the length of the radiating stub. Here, in this embodiment, the length of the radiating stub can be set according to the satellite frequency band in which it operates.

[0071] For example, in satellite communications, the operating frequency for receiving signals in a radiating stub is 2.2 GHz, and the corresponding length of the radiating stub can be set to 30 mm.

[0072] The aforementioned feed point can feed signals into the radiating stub to enable the radiating stub to operate and transmit wireless signals. Here, the feed point can also transmit the signals converted by the radiating stub to the radio frequency module to enable wireless signal reception.

[0073] It should be noted that the RF module includes: a first amplifier, an antenna switch, a filter, a duplexer, and a second amplifier. The first amplifier amplifies the electrical signals in the signal output channel. The antenna switch switches between receiving and transmitting electrical signals, and between different frequency bands of the antenna. The filter allows signals from a specific frequency band to pass through while filtering out signals from other frequency bands. The duplexer isolates the transmitted and received electrical signals, enabling the antenna to function properly when simultaneously receiving and transmitting wireless signals. The second amplifier amplifies the electrical signals in the signal receiving channel. Thus, the RF module enables both receiving and transmitting electrical signals, allowing the radiator to better transmit and receive wireless signals.

[0074] The aforementioned upper frame point is the upper frame point of the first variable impedance component connecting to the radiating stub. This upper frame point and the feed point are located at different positions on the radiating stub. For example, the upper frame point and the feed point can be located at the same end of the radiating stub, or at different ends of the radiating stub, or between the two ends of the radiating stub. This disclosure does not limit the scope of the embodiments.

[0075] It should be noted that the upper frame point and the power supply point can be made of materials such as iron, copper foil, or conductors used in the Laser Direct Structuring (LDS) process.

[0076] In this embodiment, one end of the first variable impedance component is connected to the upper frame point of the radiating stub, and the other end is grounded. This first variable impedance component can perform impedance tuning on the antenna module's transmission and reception of wireless signals, thereby adjusting the antenna pattern.

[0077] It should be noted that the first variable impedance component may include at least one module with a variable impedance value. When there are multiple modules with variable impedance values, these multiple modules with variable impedance values ​​can be connected in series and parallel between the upper frame point and ground. In this way, the antenna pattern of the antenna module can be changed when the impedance value of any one of the multiple modules with variable impedance values ​​changes.

[0078] For example, the first variable impedance component includes a variable resistor, a variable capacitor, and / or a variable inductor, etc., and the embodiments disclosed herein are not limited thereto.

[0079] In this embodiment, the first variable impedance component is used to adjust the current reversal point of the radiating stub. Since the antenna pattern of the antenna module differs depending on the position of the current reversal point, this embodiment can adjust the antenna pattern of the antenna module by adjusting the impedance of the first variable impedance component, thereby achieving antenna pattern reconstruction.

[0080] It should be noted that adjusting the antenna pattern of the antenna module may include adjusting the direction of the antenna pattern so that it is better pointed at the satellite, thereby adapting the antenna pattern to the direction of arrival of the satellite wave. In this way, the signal strength between the antenna module and the satellite in this embodiment is optimal, achieving higher quality satellite communication.

[0081] For example, Figure 2 This is a schematic diagram illustrating the structure of a conventional Tiantong satellite antenna according to an exemplary embodiment. Figure 2 As shown, the feed terminal 201 of the existing Tiantong satellite antenna is connected to the antenna stub 202, and the grounding capacitor 203 and grounding inductor 204 are connected at different locations on the connection line between the antenna stub 202 and the feed terminal 201. The end of the antenna stub 202 is in an open state and is not connected to the matching ground.

[0082] Figure 3 This is an antenna pattern of a conventional Tiantong satellite antenna when a mobile phone is placed perpendicular to the ground plane, according to an exemplary embodiment. Figure 3As shown, when a mobile phone with the existing Tiantong satellite antenna is placed perpendicular to the ground plane, the angle θ between the main lobe direction of the antenna in the mobile phone and the vertical direction (i.e., the direction perpendicular to the ground plane) is 5 degrees. Figure 4 This is a schematic diagram illustrating a mobile phone connecting to a satellite according to an exemplary embodiment. Figure 4 As shown, the angle formed by rotating the antenna module horizontally clockwise from due north to the direction of the antenna main lobe is the antenna azimuth angle θ1; the angle between the direction of the antenna main lobe and the ground plane is the antenna downtilt angle θ2.

[0083] It should be noted that the angle between the direction of the satellite's incoming wave and the ground plane will change depending on the user's location. Consequently, the angle between the main lobe direction of the user's mobile phone antenna and the direction of the satellite's incoming wave will also change. Therefore, the user needs to constantly adjust the angle of the mobile phone to make the main lobe direction of the antenna in the mobile phone match the direction of the satellite's incoming wave in order to improve communication quality.

[0084] Based on this, this embodiment proposes an antenna module with a first variable impedance component. One end of this first variable impedance component is connected to the upper frame point of the radiating stub, and the other end is grounded, used to adjust the current reversal point of the radiating stub. In other words, this embodiment no longer connects capacitors and inductors with fixed impedance values, but rather a first variable impedance component with a variable impedance value. The current reversal point of the radiating stub adjusted by the first variable impedance component can change the antenna pattern, ensuring that the antenna pattern of the antenna module is always adapted to the direction of satellite arrival, thereby achieving optimal signal strength between the antenna module and the satellite. Thus, communication in this embodiment is not geographically limited, and communication quality and user experience can be improved without adjusting the angle of the electronic device with the antenna module.

[0085] In some embodiments, such as Figure 1 As shown, the radial branch 100 has a first end and a second end;

[0086] The power supply point 101 is located at the first end;

[0087] The upper frame point 102 is located at the second end;

[0088] When the radiating stub 100 is operating in half-wavelength mode, the impedance of the first variable impedance component 103 is different, and the position of the current reversal point formed by the radiating stub 100 is different.

[0089] In this embodiment, the feed point is located at the first end and the upper frame point is located at the second end. Here, the feed point can be located at the outer edge of the first end and the upper frame point at the outer edge of the second end to maximize the current flow path formed by the radiating stubs, thereby improving antenna performance.

[0090] It should be noted that the radiating branch can be formed by the part between two gaps in the frame of the electronic device. Here, the power supply point can be set as close as possible to one gap, and the upper frame point can be set as close as possible to the other gap.

[0091] In this embodiment of the disclosure, when the radiating stub is operating in half-wavelength mode, if the first variable impedance component is not connected to the upper frame point of the second end, the position of the current reversal point formed by the radiating stub based on the half-wavelength mode (i.e., the first mode) is located at the second end.

[0092] If the first variable impedance component is connected to the upper frame point of the second end, the radiating stub will form a second mode with current opposite to the half-wavelength mode. As the impedance of the first variable impedance component changes, the second mode and the first mode will increase or decrease in opposite directions, thereby changing the position of the current reversal point formed by the radiating stub.

[0093] It should be noted that when the radiating stub operates in half-wavelength mode, the current generated by the radiating stub flows from the first end to the second end, and the direction of this current changes at a preset position. This preset position is the current reversal point.

[0094] In this embodiment of the disclosure, when the impedance of the first variable impedance component is different, the position of the current reversal point formed by the radiating branch will move between the second end and the feed point, so that the position of the current reversal point formed by the radiating branch can be close to the feed point or far away from the feed point.

[0095] In some embodiments, the impedance of the first variable impedance component is positively correlated with the distance from the location of the current reversal point formed by the radiating stub to the feed point.

[0096] In other words, the lower the impedance of the first variable impedance component, the smaller the distance from the current reversal point formed by the radiating stub to the feed point; the higher the impedance of the first variable impedance component, the larger the distance from the current reversal point formed by the radiating stub to the feed point. Therefore, by changing the impedance of the first variable impedance component, the location of the current reversal point formed by the radiating stub can be changed.

[0097] It is understood that different impedances of the first variable impedance component result in different positions of the current reversal points formed by the radiating stubs. Furthermore, the position of the current reversal point changes the orientation of the antenna pattern. Therefore, by adjusting the impedance of the first variable impedance component, the position of the current reversal point on the radiating stub can be changed, thereby altering the antenna pattern. Thus, the communication of this embodiment is not geographically limited, and communication quality and user experience can be improved without adjusting the angle of the electronic device with the antenna module.

[0098] In some embodiments, such as Figure 1 As shown, the first variable impedance component 103 includes:

[0099] The first variable inductor module 103a has one end connected to the upper frame point 102 and the other end grounded.

[0100] And / or,

[0101] The first variable capacitor module 103b has one end connected to the upper frame point 102 and the other end grounded, and is arranged in parallel with the first variable inductor module 103a.

[0102] The aforementioned first variable inductor module may include one or more variable inductor devices. These multiple variable inductor devices may be connected in series or parallel, and this disclosure does not limit this.

[0103] The aforementioned first variable capacitor module may include one or more variable capacitor components. These multiple variable capacitor components may be connected in series or parallel, and this disclosure does not limit this arrangement.

[0104] It should be noted that the impedance of the first variable impedance component can be changed by adjusting the inductance value of the first variable inductor module, the impedance of the first variable impedance component can be changed by adjusting the capacitance value of the first variable capacitor module, or the impedance of the first variable impedance component can be changed by simultaneously adjusting the inductance value of the first variable inductor module and the capacitance value of the first variable capacitor module. This disclosure does not impose any limitations on the embodiments.

[0105] It is understandable that by adjusting the first variable inductor module and / or the first variable capacitor module to change the impedance of the first variable impedance component, the adjustment of the first variable impedance component can be made more flexible.

[0106] For example, Figure 5 This is a schematic diagram illustrating the movement of the current reversal point towards the feed point according to an exemplary embodiment. For example... Figure 5 As shown, when the first variable impedance component is not connected to the second end of the radiating stub, the current reversal point of the radiating stub is located at the second end.

[0107] When the first variable inductor module is connected to the upper frame point 102 of the radiating stub and the first variable inductor module has the first inductance value, the current reversal point of the radiating stub will move from the second end to the feed point 101 to the first position A.

[0108] When the first variable inductor module is connected to the upper frame point 102 of the radiating stub and the first variable inductor module has the second inductance value, the current reversal point of the radiating stub will continue to move from the first position A to the feed point 101 to the second position B.

[0109] When the first variable inductor module is connected to the upper frame point 102 of the radiating stub, and the first variable inductor module has the third inductance value, the current reversal point of the radiating stub will continue to move from the second position B to the feed point 101 to the third position C.

[0110] It should be noted that the first inductance value is greater than the second inductance value, and the second inductance value is greater than the third inductance value. The first position is located between the second end and the second position, the second position is located between the first position and the third position, and the third position is located between the second position and the feed point.

[0111] It is understandable that, with the first variable capacitor module remaining unchanged, the inductance value of the first variable inductor module is positively correlated with the distance from the location of the current reversal point formed by the radiating stub to the feed point. That is, the smaller the inductance value of the first variable inductor module, the smaller the distance from the location of the current reversal point formed by the corresponding radiating stub to the feed point.

[0112] In this embodiment of the disclosure, when the mobile phone with the antenna module is placed vertically, i.e., the mobile phone is always placed perpendicular to the ground plane, the smaller the inductance value of the first variable inductor module, the smaller the distance from the current reversal point to the feed point, and consequently the larger the angle between the antenna main lobe direction and the vertical direction of the antenna module. That is, the distance from the current reversal point to the feed point is negatively correlated with the angle between the antenna main lobe direction and the vertical direction of the antenna module.

[0113] like Figure 6 As shown, if the inductance value of the first variable inductor module is infinitely large, then the angle between the main lobe direction of the antenna module and the vertical direction is 5 degrees.

[0114] like Figure 7 As shown, if the inductance value of the first variable inductor module is 6 nanohenries, then the angle between the main lobe direction of the antenna module and the vertical direction is 10 degrees.

[0115] like Figure 8 As shown, if the inductance value of the first variable inductor module is 3 nanohenries, then the angle between the main lobe direction of the antenna module and the vertical direction is 20 degrees.

[0116] like Figure 9 As shown, if the inductance value of the first variable inductor module is 2.2 nanohenries, then the angle between the main lobe direction of the antenna module and the vertical direction is 32 degrees.

[0117] in, Figure 6 , Figure 7 , Figure 8 and Figure 9 In the image, the black arrow points in the direction of the antenna module's main lobe.

[0118] It can be seen that when the mobile phone is always placed vertically on the ground plane, the angle between the main lobe direction of the antenna module and the vertical direction (that is, the angle between the maximum radiation direction of the antenna module and the vertical direction) is in the range of 5 degrees to 32 degrees.

[0119] Verification showed that the angles between the southernmost Zengmu Reef and the northernmost Mohe and the Tiantong satellite are 13 degrees and 62 degrees, respectively. Since the beamwidth is ±30 degrees, and the angle between the antenna module's maximum radiation direction and the vertical direction is 32 degrees, the angle of the antenna module at maximum beamwidth is the sum of 32 degrees and 30 degrees, i.e., 62 degrees. Here, beam scanning reveals that the antenna gain at 62 degrees is less than 1 dB lower than the antenna module's maximum gain, thus enabling better satellite communication.

[0120] In some embodiments, such as Figure 1 As shown, the antenna module includes:

[0121] Feed source 104;

[0122] A fixed capacitor assembly 105 is connected to the connection line between the feed source 104 and the feed point 101;

[0123] The second variable impedance component 106 has one end connected to the connection line between the fixed capacitor component 105 and the feed point 101, and the other end grounded.

[0124] In this embodiment of the disclosure, the antenna module can be tuned to change the resonant frequency of the antenna module by means of a fixed capacitor component and a second variable impedance component.

[0125] It should be noted that the adjustment of the second variable impedance component needs to be compatible with the adjustment of the first variable impedance component, so that the antenna module can communicate at a preset resonant frequency based on the antenna pattern adjusted by the first variable impedance component.

[0126] The aforementioned fixed capacitor assembly can consist of one or more capacitor components. When there are multiple capacitor components, they can be connected in series and parallel on the connection line between the feed source and the feed point.

[0127] The different impedances of the aforementioned second variable impedance components correspond to different impedances on the connection line between the feed source and the feed point. This second variable impedance component may also include at least one module with a variable impedance value. When there are multiple modules with variable impedance values, these multiple modules can be connected in series and parallel between the upper frame point and ground. Thus, when the impedance value of any one of the multiple variable impedance modules changes, the impedance on the connection line between the feed source and the feed point can be changed.

[0128] For example, the second variable impedance component may include a variable resistor, a variable capacitor, and / or a variable inductor, etc., and the embodiments disclosed herein are not limited thereto.

[0129] It is understandable that, considering that the first variable impedance component may affect the resonant frequency of the radiating stub when the antenna pattern is changed, this embodiment of the present disclosure proposes to set a second variable impedance component. By adjusting the first and second variable impedance components, the direction of the antenna pattern can be adjusted without changing the operating frequency of the radiating stub, so that the antenna pattern of the antenna module can be adapted to the direction of the incoming satellite wave.

[0130] In some embodiments, such as Figure 1 As shown, the second variable impedance component 106 includes:

[0131] The second variable inductor module 106a has one end connected to the connection line between the fixed capacitor assembly 105 and the feed point 101, and the other end grounded.

[0132] And / or,

[0133] The second variable capacitor module 106b has one end connected to the connection line between the fixed capacitor assembly 105 and the power supply point 101, and the other end grounded, and is arranged in parallel with the second variable inductor module 106a.

[0134] The aforementioned second variable inductor module may include one or more variable inductor devices. These multiple variable inductor devices may be connected in series or parallel, and this disclosure does not limit this arrangement.

[0135] The aforementioned second variable capacitor module may include one or more variable capacitor components. These multiple variable capacitor components may be connected in series or parallel, and this disclosure does not limit this arrangement.

[0136] It should be noted that the impedance of the second variable impedance component can be changed by adjusting the inductance value of the second variable inductor module, the impedance of the second variable impedance component can be changed by adjusting the capacitance value of the second variable capacitor module, or the impedance of the second variable impedance component can be changed by simultaneously adjusting the inductance value of the second variable inductor module and the capacitance value of the second variable capacitor module. This disclosure does not impose any limitations on the embodiments.

[0137] It is understandable that by adjusting the second variable inductor module and / or the second variable capacitor module to change the impedance of the second variable impedance component, the adjustment of the second variable impedance component can be made more flexible.

[0138] This disclosure also provides an electronic device. The electronic device includes the antenna module described in one or more of the above embodiments.

[0139] In this embodiment of the disclosure, the radiating branches of the antenna module can be disposed at different locations in the electronic device.

[0140] In some embodiments, the radiating stubs of the antenna module are disposed on the top of the electronic device. This reduces the obstruction of the radiating stubs when holding the electronic device and improves the communication performance of the antenna module for satellite communication.

[0141] In this embodiment of the disclosure, the radiating branch, disposed on the top of the electronic device, may include: the top frame of the electronic device comprising at least a portion of conductive material, the top frame having two slits, and the top frame between the two slits constituting the radiating branch. That is, the radiating branch can be formed by reusing the top frame.

[0142] It is understood that the electronic device includes an antenna module, which is equipped with a first variable impedance component. One end of the first variable impedance component is connected to the upper frame point of the radiating stub, and the other end is grounded. Different impedances of the first variable impedance component result in different positions of the current reversal points in the radiating stubs, thus altering the antenna pattern of the antenna module. In other words, this embodiment no longer connects capacitors and inductors with fixed impedance values, but rather connects a first variable impedance component with a variable impedance value. This first variable impedance component allows adjustment of the antenna pattern of the antenna module, ensuring that the antenna pattern always aligns with the direction of satellite arrival. This improves communication quality and user experience without adjusting the angle of the electronic device with the antenna module.

[0143] This disclosure also provides an antenna adjustment method, which is applied to the electronic device described above. Figure 10 This is a flowchart illustrating an antenna adjustment method according to an exemplary embodiment. Figure 10 As shown, the method for adjusting the antenna in an electronic device includes the following steps:

[0144] Step S1001: Detect the communication quality of the electronic device performing satellite communication;

[0145] Step S1002: If the communication quality does not meet the preset conditions, adjust the impedance of the first variable impedance component of the antenna module in the electronic device.

[0146] Step S1003: Perform satellite communication based on the adjusted antenna module.

[0147] In this embodiment of the disclosure, the communication quality of the electronic device performing satellite communication includes: detecting the communication rate, number of communication frames, and / or error rate of the electronic device performing satellite communication.

[0148] The above communication quality does not meet the preset conditions, which may include: the communication rate of the electronic device for satellite communication is less than a preset rate threshold, the number of communication frames of the electronic device for satellite communication is less than a preset frame number threshold, and / or the error rate of the electronic device for satellite communication is greater than a preset error threshold.

[0149] The aforementioned adjustment of the impedance of the first variable impedance component of the antenna module in the electronic device may include: adjusting the impedance of the first variable inductor module and / or the impedance of the first variable capacitor module.

[0150] It is understood that the embodiments of this disclosure no longer use capacitors and inductors with fixed impedance values, but rather a first variable impedance component whose impedance value can change. This first variable impedance component allows adjustment of the antenna pattern of the antenna module, ensuring that the antenna pattern always aligns with the direction of satellite arrival, thereby achieving optimal signal strength between the antenna module and the satellite. Thus, the communication of the embodiments of this disclosure is not geographically limited, and communication quality and user experience can be improved without adjusting the angle of the electronic device with the antenna module.

[0151] In some embodiments, adjusting the impedance of the first variable impedance component of the antenna module in the electronic device includes:

[0152] The impedance of the first variable impedance component and the impedance of the second variable impedance component of the antenna module are adjusted.

[0153] In this embodiment of the disclosure, adjusting the impedance of the first variable impedance component may include adjusting the impedance of the first variable inductor module and / or the impedance of the first variable capacitor module.

[0154] Adjusting the impedance of the second variable impedance component may include adjusting the impedance of the second variable inductor module and / or the impedance of the second variable capacitor module.

[0155] It is understandable that, considering that the first variable impedance component may affect the resonant frequency of the radiating stub when the antenna pattern is changed, this embodiment of the present disclosure proposes to set a second variable impedance component. By adjusting the first and second variable impedance components, the direction of the antenna pattern can be adjusted without changing the operating frequency of the radiating stub, so that the antenna pattern of the antenna module can be adapted to the direction of the incoming satellite wave.
