Technical Field

[0001] This disclosure relates to the field of communication technology, and more particularly to the field of antennas. More specifically, this disclosure provides an electronic device and a method for controlling the electronic device. Background Technology

[0002] In wireless communication scenarios, electronic devices such as computers and mobile phones often need to work in complex and ever-changing environments, sometimes resulting in uneven signal coverage and insufficient gain in specific directions.

[0003] In related technologies, the antenna systems of electronic devices have fixed radiation patterns that cannot be dynamically adjusted according to actual communication needs. Furthermore, due to antenna environmental limitations and miniaturization design, the radiation pattern is greatly affected, resulting in poor omnidirectional coverage and difficulty in adapting to dynamically changing communication requirements. Summary of the Invention

The control component is also capable of adjusting the radiation pattern of the antenna module by regulating the time difference of feeding the feed terminals on the first and second antennas to form a target phase difference between the first and second antennas.

[0006] According to another embodiment of this disclosure, the control component includes a signal distributor for establishing a feed path between the radio frequency front-end circuit of the electronic device and a first feed terminal on the first antenna and a second feed terminal on the second antenna, a phase shifter disposed between the signal distributor and the first feed terminal and / or between the signal distributor and the second feed terminal, and a control unit for adjusting the operating parameters of the phase shifter; the control unit can adjust the operating parameters of the phase shifter according to the target communication requirements of the electronic device and / or the environmental change information of the spatial environment, so that the radio frequency front-end circuit feeds the first feed terminal and the second feed terminal with a target time difference, so that a target phase difference is formed between the first antenna and the second antenna, thereby adjusting the radiation pattern of the antenna module.

[0007] According to another embodiment of this disclosure, the phase shifter includes a plurality of first phase shifters connected in parallel between the signal distributor and the first feed terminal. The plurality of first phase shifters introduce different delays or change the transmission path to make the signal output from the radio frequency front-end circuit produce different phase shifts relative to the signal fed into the first feed terminal.

[0008] According to another embodiment of this disclosure, the phase shifter includes a plurality of first phase shifters connected in parallel between the signal distributor and the first feed terminal, and a plurality of second phase shifters connected in parallel between the signal distributor and the second feed terminal. The plurality of first phase shifters enable the signal output from the RF front-end circuit to have different phase shifts relative to the signal fed into the first feed terminal, and the plurality of second phase shifters enable the signal output from the RF front-end circuit to have different phase shifts relative to the signal fed into the second feed terminal. The control unit can control a target second phase shifter among the plurality of second phase shifters to be in an active state and the other second phase shifters to be in an inactive state according to the target communication requirements of the electronic device and / or the environmental change information of the space environment, so that a second phase difference is formed between the first antenna and the second antenna, thereby giving the antenna module a second radiation pattern; or, the control unit can control a target first phase shifter among the plurality of first phase shifters and a target second phase shifter among the plurality of second phase shifters to be in an active state and the other phase shifters to be in an inactive state according to the target communication requirements of the electronic device and / or the environmental change information of the space environment, so that a third phase difference is formed between the first antenna and the second antenna, thereby giving the antenna module a third radiation pattern.

[0009] According to another embodiment of this disclosure, the phase shift amounts that can be achieved by the plurality of first phase shifters are distributed in a first arithmetic sequence, and the phase shift amounts that can be achieved by the plurality of second phase shifters are distributed in a second arithmetic sequence; the tolerance of the first arithmetic sequence is different from the tolerance of the second arithmetic sequence.

[0011] According to another embodiment of this disclosure, the device body includes a first body and a second body rotatably connected. The first body and the second body can rotate to different included angle ranges to allow the electronic device to switch to different device forms. When the electronic device switches to different device forms, the control unit can control the operating state of a target phase shifter among multiple first phase shifters and / or multiple second phase shifters, so that the radiation pattern of the antenna module adapts to the switched device form. Alternatively, when the electronic device switches to different communication modes, the control component can control the operating state of a target phase shifter among multiple first phase shifters and / or multiple second phase shifters, so that the radiation pattern of the antenna module adapts to the switched communication mode.

[0012] According to another embodiment of this disclosure, the device body includes a first body and a second body rotatably connected; the electronic device also includes a display screen having a first screen area and a second screen area, the first screen area being displayed on a first surface of the first body and the second screen area being housed in the first body or the second body, in a first usage mode, the second screen area being pulled out from the first body or the second body, and in a second usage mode being housed in the first body or the second body, an antenna module being disposed on the first body, and the radiation pattern of the antenna module being different in the first usage mode and the second usage mode; or, the antenna module being disposed at the rotatable connection between the first body and the second body, and the center distance between the first antenna and the second antenna being 1 / 2, 1 / 3 or 1 / 4 of the wavelength of the target frequency band.

[0037] The embodiments of this disclosure will now be described with reference to the accompanying drawings. Various details of the embodiments of this disclosure are included to aid understanding and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0038] In the technical solution disclosed herein, the collection, storage, use, processing, transmission, provision, disclosure, and application of data (including but not limited to user personal information) comply with the provisions of relevant laws and regulations, and necessary confidentiality measures and desensitization processing have been adopted, and do not violate public order and good morals.

[0039] In one related technology, controllable parasitic elements can be added to the near field of an antenna, and the radiation pattern of the antenna can be adjusted by controlling the grounding state of these parasitic elements through switches. For example, one parasitic element can be placed on each side of the antenna, and then the two parasitic elements can be switched on, or switched off, or the first parasitic element can be switched on and the second off, or the first parasitic element can be switched off and the second on. This can achieve four radiation patterns. However, this scheme only provides four radiation patterns, limiting the control methods. It is also more difficult to design, as it is not easy to achieve significant differences between the four radiation patterns. Furthermore, the radiation efficiency is easily affected by the parasitic elements, especially when operating in multiple frequency bands, where performance degrades significantly.

[0040] In another related technology, some electronic devices are equipped with two antennas in different locations. One antenna is selected to operate based on signal quality, while the other remains inactive. This approach can achieve significant differences in radiation patterns in two directions through antenna placement and design. However, only two fixed radiation patterns are available, thus limiting the ability to adjust the radiation pattern. Furthermore, the adjustment precision is insufficient, preventing continuous and precise control of the radiation pattern. Additionally, it suffers from design complexity, limited freedom, or the need for more antenna space and higher costs.

[0041] Figure 1 This is a schematic structural diagram of an antenna module according to an embodiment of the present disclosure.

[0042] like Figure 1 As shown, the electronic device may include a device body and an antenna module 100.

[0043] The electronic device can be a smartphone, tablet, laptop, etc. The device body can be a mobile phone frame, a laptop metal body, or an internal support structure, etc., with internal spaces for accommodating various electronic components. The antenna module 100 is disposed within the accommodating space of the device body.

[0044] The antenna module 100 includes an antenna element 110, which includes two antennas spaced apart, namely a first antenna 111 and a second antenna 112, one of which is a main antenna and the other is a secondary antenna. The two antennas can operate independently in the entire target frequency band.

[0045] The antenna module 100 also includes a control component 120. The control component 120 may include a processor (e.g., a system control chip), a combiner / power divider, a phase shifter, etc. The control component 120 is connected to a first feed terminal of the first antenna 111, and also to a second feed terminal of the second antenna 112.

[0046] On the one hand, the control component 120 can control the first antenna 111 and the second antenna 112 to transmit and receive wireless signals in the target frequency band, that is, to complete the conventional radio frequency signal transmission and reception function. The target frequency band can be 2.4GHz, 5GHz, 6GHz, 7GHz, etc.

[0047] On the other hand, the control component 120 can also regulate the time difference in feeding the feed terminals of the first antenna 111 and the second antenna 112. This feeding time difference refers to the feeding delay, that is, the time difference between when the radio frequency signal arrives at the first feed terminal and the second feed terminal. The feeding time difference between the two feed terminals on the two antennas can be controlled by controlling the difference in the propagation path length of the wireless signals transmitted and received by the two antennas. The feeding time difference can create a target phase difference between the first antenna 111 and the second antenna 112. The target phase difference can be any angle between 0 and 360 degrees, thereby adjusting the radiation pattern of the antenna module 100.

[0048] For example, during the transmission of a wireless signal, the signal is split into two paths by a combiner / power divider. One path is fed into the first antenna 111 via a phase shifter, while the other path is fed into the second antenna 112 without a phase shifter or via another phase shifter. The phase shifter causes the feed times of the first antenna 111 and the second antenna 112 to differ, resulting in interference when the electromagnetic waves radiated by the two antennas meet in space. By adjusting the feed delay, the target phase difference can be controlled to be any angle between 0 and 360°, thereby altering the radiation pattern formed by the combination of the first antenna 111 and the second antenna 112.

[0049] According to the technical solution provided in this disclosure, the two antennas in antenna unit 110 work together. If uneven signal coverage or insufficient gain in a specific direction occurs, the feeding time difference between the two antennas can be adjusted by control component 120 to form a target phase difference between the two antennas. This phase difference can change the radiation pattern synthesized by the two antennas. Therefore, by configuring different phase differences, multiple radiation patterns can be formed. The pattern synthesized from the best radiation effects of all radiation patterns in different directions can improve omnidirectional coverage, making the radiation pattern suitable for dynamically changing communication needs, and improving signal coverage quality and communication reliability.

[0050] It should be noted that, in addition to dynamically adjusting the radiation pattern according to actual needs, the above technical solution also has the following advantages: First, the radiation pattern synthesized by the two antennas can achieve higher gain in a specific direction than a single antenna. The two antennas can obtain significantly enhanced gain in all directions under different phase differences, achieving enhanced directional gain. Second, by continuously adjusting the different phase differences formed by the two antennas, the radiation pattern synthesized by the two antennas can be continuously and precisely controlled. For example, it can be adjusted in predetermined step angles within the range of 0~360°. The predetermined step angle can be any angle, such as less than or equal to 1°, or 10°, 15°, 30°, 60°, etc.; at the same time, the adjustment range is wide, achieving precise control of the radiation direction. Furthermore, the two antennas are integrated into one antenna element 110, requiring no additional assembly space. The synthesized radiation pattern is adjusted by changing the phase difference between the two antennas, without strict control of the beam and directionality, and the spacing requirements between the two antennas are low, making it suitable for the needs of miniaturized devices. In addition, the radiation pattern formed by the two antennas can operate effectively in multiple frequency bands, without being limited by a specific frequency, making it suitable for multi-frequency antenna requirements.

[0051] According to another embodiment of this disclosure, the control components include a signal distributor, a phase shifter, and a control unit.

[0052] A signal distributor is used to establish the feed path between the RF front-end circuit of an electronic device and the first feed terminal on the first antenna, as well as the feed path between the RF front-end circuit and the second feed terminal on the second antenna. The RF front-end circuit includes components such as RF chips and signal processing units, which serve as parts of the transmit and receive links, respectively. The signal distributor includes a combiner and a power divider. The power divider splits one input signal into two output signals and provides them to the two antennas. The combiner merges the two input signals from the two antennas into one output signal.

[0053] The phase shifter includes at least one first phase shifter and / or at least one second phase shifter. The first phase shifter is disposed between the signal distributor and the first feed terminal of the first antenna. The function of the first phase shifter is to introduce a controllable phase delay (phase shift angle) into the radio frequency signal fed into the first antenna. The first phase shifter can be a digital phase shifter to achieve wide-range fine phase control; alternatively, multiple fixed phase shifters can be used, and a switching system can be used to select the fixed phase shifter in operation to achieve control of different phase differences.

[0054] The second phase shifter is positioned between the signal distributor and the second feed terminal. Similarly, the function of the second phase shifter is to introduce a controllable phase delay into the radio frequency signal fed into the second antenna. It can be a digital phase shifter or a fixed phase shifter.

[0055] It can be seen that when the phase shifter includes either the first phase shifter or the second phase shifter, only the phase delay of the first antenna or the second antenna is adjusted. When the phase shifter includes both the first and second phase shifters, the phase delays of the two antennas can be adjusted simultaneously, thus creating a phase difference.

[0056] The control unit is used to regulate the operating parameters of the phase shifter, thereby adjusting the phase shift angle. If the phase shifter is a fixed phase shifter, the control unit may include a control IC and switches, and the operating parameters may include, for example, whether it is in an operating state. If the phase shifter is a dynamically adjustable digital phase shifter, the control unit may be a processor IC, and the operating parameters may include, for example, the phase shift angle.

[0057] The control unit can adjust the operating parameters of the phase shifter according to the target communication requirements of the electronic device and / or the environmental changes of the space environment, so that the radio frequency front-end circuit feeds the first feed terminal and the second feed terminal with the target time difference, so that the first antenna and the second antenna form a target phase difference, thereby adjusting the radiation pattern of the antenna module.

[0058] Target communication requirements include, for example, signal evaluation requirements, better signal quality requirements, signal strength requirements in a specific direction, and network quality requirements for running specific applications. Environmental change information includes, for example, whether the device has moved to a new spatial environment, whether it is being moved, whether it is being held or obstructed, whether any obstructions have entered the environment, whether other devices have entered or moved out of the environment, and changes in signal interference. The moment when the RF front-end circuit feeds power to the first feed terminal is designated as the first moment, and the moment when the RF front-end circuit feeds power to the second feed terminal is designated as the second moment. The target time difference is the time difference between the first and second moments.

[0059] For example, when an electronic device detects that a video conferencing application is currently running (corresponding to the target communication requirement), and its built-in sensors detect that the device has switched from a mobile state to a stationary state (e.g., placed on a table, corresponding to environmental change information), the control unit introduces a 150° phase delay into the signal fed into the first antenna by controlling a phase shifter. This creates a target phase difference of 150° between the first and second antennas, thereby shaping the antenna module into a specific radiation pattern. This radiation pattern can be enhanced in directions away from the table, thus improving the signal quality during video conferencing.

[0060] For example, when the built-in sensors of an electronic device detect a change in its position—such as a user taking a phone out of their bag and holding it to answer a call, moving from an indoor location to a location near a window, or the distance between two locations reaching a set threshold—this positional change triggers the control unit to evaluate the electronic device's target communication needs, such as signal quality requirements or better signal strength requirements. If the evaluation indicates a need for better signal quality, the feeding time difference between the feed terminals of the first and second antennas can be adjusted to change the radiation pattern. During the adjustment process, multiple different feeding time differences can be used to obtain multiple radiation patterns. After obtaining each new radiation pattern, the signal strength is detected, and the antenna module is configured to form the radiation pattern with the strongest signal strength from among the multiple radiation patterns. For example, if the strongest radiation pattern is a 30° phase difference, a target phase difference of 30° can be formed between the first and second antennas, thereby configuring the antenna module to form a specific radiation pattern to improve signal strength.

[0061] In this embodiment, the electronic device can automatically adjust the feed delay of the two antennas according to the target communication requirements and / or the environmental changes in the space environment, thereby changing the radiation pattern of the antenna module and achieving the effect of adaptively improving communication performance according to communication requirements and environmental changes.

[0062] Figure 2 This is a schematic structural diagram of an antenna module according to another embodiment of the present disclosure.

[0063] In this embodiment, the antenna module 200 includes an antenna unit 210 and a control component 220. The antenna unit 210 includes a first antenna 211 and a second antenna 212. The control component 220 includes a signal distributor, a phase shifter, and a control unit.

[0064] The phase shifter includes multiple first phase shifters 221, which are connected in parallel between the signal distributor and the first feed terminal of the first antenna 211. By introducing different delays or changing the transmission path, the multiple first phase shifters 221 cause different phase shifts in the signal output from the RF front-end circuit relative to the signal fed into the first feed terminal. The control unit can control the target first phase shifter among the multiple first phase shifters 221 to be in an active state and the other first phase shifters to be in an inactive state, based on the target communication requirements of the electronic device and / or environmental changes in the surrounding space, thereby creating a first phase difference between the first antenna 211 and the second antenna 212, and thus giving the antenna module 200 a first radiation pattern.

[0065] For example, each first phase shifter 221 can be a delay line, and the length of the delay lines of each first phase shifter 221 can be different. Different lengths of delay lines introduce different delays when the signal passes through, resulting in a fixed phase shift relative to the original signal when the signal from the RF front-end circuit, after passing through the signal distributor and the first phase shifter 221, reaches the first feed terminal. The number and phase shift parameters of the first phase shifters 221 can be configured according to design requirements. Figure 2 The intermediate phase shifter includes six parallel first phase shifters 221. These six first phase shifters 221 can, for example, introduce phase shifts of 0°, 60°, 120°, 180°, 240°, and 300° respectively, achieving phase difference control in 60° steps within the 0~360° range, thereby realizing six different first radiation patterns. In other examples, the number of first phase shifters 221 can be increased to achieve smaller phase difference steps, or the number of first phase shifters 221 can be reduced while meeting performance requirements, simplifying the design and reducing costs.

[0066] The control unit includes a control circuit and switches, each corresponding to a first phase shifter 221. The switches control the corresponding first phase shifter 221 to switch between an active and inactive state. For example, the control circuit closes a second switch while simultaneously opening the others, thus putting the second first phase shifter 221 in an active state (i.e., on state) and the others in an inactive state (i.e., off state). This creates a 60° phase difference between the first antenna 211 and the second antenna 212, and the antenna module 200 has a first radiation pattern corresponding to this 60° phase difference.

[0067] This embodiment employs multiple first phase shifters 221 connected in parallel, and uses a switch to select the target first phase shifter for conduction, providing a simple and cost-effective phase control method. Although the achievable first phase difference is discrete (e.g., 60° steps), by reasonably setting the number of first phase shifters 221 and the phase offset value, fine and wide-range radiation pattern control can be achieved to meet application requirements.

[0068] Figure 3 This is a schematic structural diagram of an antenna module according to another embodiment of the present disclosure.

[0069] In this embodiment, the antenna module 300 includes an antenna unit 310 and a control component 320. The antenna unit 310 includes a first antenna 311 and a second antenna 312. The control component 320 includes a signal distributor, a phase shifter, and a control unit.

[0070] The phase shifter includes multiple first phase shifters 321 and multiple second phase shifters 322. The multiple first phase shifters 321 are connected in parallel between the signal distributor and the first feed terminal of the first antenna 311, enabling the signal output from the RF front-end circuit to have a different phase shift relative to the signal fed into the first feed terminal. Similarly, the multiple second phase shifters 322 are connected in parallel between the signal distributor and the second feed terminal of the second antenna 312, enabling the signal output from the RF front-end circuit to have a different phase shift relative to the signal fed into the second feed terminal. For example, Figure 3 The diagram shows six first phase shifters 321 connected in parallel, capable of introducing phase shifts of 0°, 60°, 120°, 180°, 240°, and 300° respectively; and four second phase shifters 322 connected in parallel, capable of introducing phase shifts of 0°, 15°, 30°, and 45° respectively.

[0071] The control unit includes a control circuit and switches. The switches include a first switch corresponding to the first phase shifter 321 and a second switch corresponding to the second phase shifter 322. The switches control the corresponding phase shifters to switch between operating and non-operating states.

[0072] In one example, the target phase difference can be adjusted by controlling only the first phase shifter 321. This adjustment method can be referenced above; for example, the control circuit controls the second first switch to close while simultaneously controlling the other first switches to open. Assuming that the first second phase shifter 322, used to introduce a 0° phase shift, is turned on by default, this scheme results in a 60° first phase difference between the first antenna 311 and the second antenna 312, and the antenna module 300 has a first radiation pattern corresponding to this 60° first phase difference.

[0073] In another example, the target phase difference can be adjusted by controlling only the second phase shifter 322. The control unit can control the target second phase shifter 322 to be in an active state and the other second phase shifters 322 to be in an inactive state based on the target communication requirements of the electronic device and / or environmental changes in the surrounding space environment. This creates a second phase difference between the first antenna 311 and the second antenna 312, thereby giving the antenna module 300 a second radiation pattern. For example, the control circuit controls the second second switch to close while simultaneously controlling the other second switches to open, thus putting the second second phase shifter 322 in a conducting state and the other second phase shifters 322 in a non-conducting state. Assuming that the first first phase shifter 321, used to introduce a 0° phase shift, is defaulted to conduct at this time, a second phase difference of 345° is formed between the first antenna 311 and the second antenna 312, and the antenna module 300 has a second radiation pattern corresponding to the 345° second phase difference.

[0074] In another example, the first phase shifter 321 and the second phase shifter 322 can be controlled simultaneously to adjust the target phase difference. The control unit can control the target first phase shifter among the multiple first phase shifters 321 and the target second phase shifter among the multiple second phase shifters 322 to be in an active state, while the other phase shifters are in an inactive state, so that a third phase difference is formed between the first antenna 311 and the second antenna 312, thereby giving the antenna module 300 a third radiation pattern.

[0075] For example, the control circuit controls the second first switch to close and the second second switch to close, while simultaneously controlling the other first switches and other second switches to open, thereby putting the second first phase shifter 321 and the second second phase shifter 322 into a conducting state, while the other first phase shifters 321 and other second phase shifters 322 into a non-conducting state. At this time, a third phase difference of 45° is formed between the first antenna 311 and the second antenna 312, and the antenna module 300 has a third radiation pattern corresponding to the third phase difference of 45°.

[0076] Understandably, the first antenna 311 is configured with a first phase shifter 321 that steps every 60° within the 0~360° range, and the second antenna 312 is configured with a second phase shifter 322 that steps every 15° within the 0~45° range. By selecting different first phase shifters 321 and second phase shifters 322 to be turned on, phase difference control in 15° steps within the 0~360° range can be achieved. Compared to controlling only the first phase shifter 321 or the second phase shifter 322, this example uses fewer phase shifters, and by combining the first phase shifters 321 and 322 in operation, more discrete phase differences can be obtained, thus achieving more radiation patterns.

[0077] It should be noted that this embodiment uses multiple first phase shifters 321 to achieve a step of 60° within the range of 0~360°, and multiple second phase shifters 322 to achieve a step of 15° within the range of 0~45° as an example for illustration. In other embodiments, each first phase shifter 321 and each second phase shifter 322 can be configured to achieve any angle within the range of 0~360°. For example, the phase offsets corresponding to the multiple first phase shifters 321 are 30°, 50°, 70°, and 100°, and the phase offsets corresponding to the multiple second phase shifters 322 are 10, 20, 40, and 80 degrees, etc.

[0078] According to another embodiment of this disclosure, the phase shifts achievable by each of the plurality of first phase shifters are distributed according to a first arithmetic sequence, and the phase shifts achievable by each of the plurality of second phase shifters are distributed according to a second arithmetic sequence. The tolerances of the first arithmetic sequence and the second arithmetic sequence are different. For example, referring to the above, the plurality of first phase shifters achieve a 60° step in the range of 0 to 360°, and the plurality of second phase shifters achieve a 15° step in the range of 0 to 45°, thus combining to form a phase difference with a 15° step in the range of 0 to 360°. By configuring fixed phase shifting units of different precision for the two antennas respectively, more and more uniformly distributed phase differences can be combined to achieve small-step phase difference adjustment, achieving a precise control effect similar to that of a digital phase controller, and improving the flexibility of phase difference control.

[0079] For example, the antenna module can form 24 different radiation patterns. It can be adjusted to each pattern, and the signal strength (RSSI) recorded. Then, the pattern with the strongest signal is selected as the one to use. After determining the desired pattern, the signal strength can be periodically checked and compared to the recorded strength from the previous selected pattern. If significant fluctuations occur (due to environmental changes, relocation, etc.) exceeding a set threshold, the antenna module can be readjusted to each of the 24 radiation patterns, and the strongest pattern can be selected again based on signal strength.

[0080] According to another embodiment of this disclosure, a plurality of first phase shifters and a plurality of second phase shifters constitute multiple delay lines forming different transmission paths. Each phase shifter is an independent transmission line, which can employ a serpentine line or other forms to achieve phase delay while reducing size. The structural parameters of the delay lines of different phase shifters are different. For example, the physical lengths of the delay lines are different, and the path length for signal propagation affects the phase delay. For another example, the bending structure types of the delay lines are different, such as straight lines or serpentine bends, thereby increasing the physical length within a limited space. For yet another example, the materials of the delay lines are different; different materials have different dielectric constants, thus affecting the phase delay. During operation, different phase delays can be achieved by selecting delay lines with different structural parameters through a switch.

[0081] According to another embodiment of this disclosure, at least one of the plurality of first phase shifters and the plurality of second phase shifters is a delay line with an adjustable transmission path. For example, a phase shifter itself is a main delay line with a plurality of switchable extension segments along the line. By controlling the switch with a control unit, the effective length of the phase shifter can be dynamically changed, thereby achieving different phase delays.

[0082] According to another embodiment of this disclosure, the first antenna and the second antenna have the same structural parameters, such as the same size, shape, and material, thereby simplifying the structural design of the antenna module. Alternatively, the structures of the first antenna and the second antenna are centrally symmetrical or axially symmetrical. Alternatively, the two antennas may employ complementary structures, thus adapting to asymmetrical layout spaces. In practical applications, the structures of the two antennas can be flexibly selected according to the actual layout space to meet layout requirements.

[0083] For example, both the first and second antennas are inverted-F type antennas, or complementary antennas where one is an inverted-F type antenna and the other is an inverted-F type antenna. It should be noted that this disclosure primarily modifies the radiation pattern by adjusting the phase difference between the two antennas, and does not impose requirements on the antenna structure. Therefore, the antenna structure can be designed according to actual needs, for example, designed as... Figure 1 The antenna structure shown.

[0084] According to another embodiment of this disclosure, the electronic device can be a foldable smartphone, laptop computer, or similar device. The electronic device includes an antenna module and a device body. The device body includes a first body and a second body that are rotatably connected. The first body and the second body can rotate to different angle ranges to allow the electronic device to switch between different device forms. Taking a laptop computer as an example, the first body can be a body that houses the display screen, and the second body can be a body that houses the keyboard.

[0085] Electronic devices come in various forms, including note-taking (approximately 90°~120° angle), tablet (approximately 360° angle, i.e., screen facing outwards when closed), book, tent (approximately 270° angle, placed in an inverted V shape), and closed-top forms. If the electronic device is a rollable device, such as a rollable laptop, its form factor can also include a roll-in form and an unfolded form.

[0086] When an electronic device switches to a different device form, the control unit can control the operating state of the target phase shifter among multiple first phase shifters and / or multiple second phase shifters, so that the radiation pattern of the antenna module can be adapted to the switched device form.

[0087] For example, the electromagnetic environment and obstruction conditions of the antenna module will change under different device configurations. Therefore, in this embodiment, when the electronic device switches to different device configurations, the control unit can automatically select a target first phase shifter from multiple first phase shifters and / or a target second phase shifter from multiple second phase shifters based on information detected by sensors such as Hall sensors and angle sensors, and put the target first phase shifter and / or target second phase shifter into an active state, so that the radiation pattern of the antenna module adapts to the switched device configuration.

[0088] In one example, the antenna module can generate 24 different radiation patterns. It can be adjusted to each pattern, and the signal strength (RSSI) recorded. The pattern with the strongest signal is then selected as the one to use. After determining the desired pattern, the form factor of the electronic device can be periodically monitored. If a change from one form to another is detected, the antenna module is readjusted to the 24 different radiation patterns, and the pattern with the strongest signal is selected again based on the signal strength.

[0089] In one example, the correspondence between the device form factor of an electronic device and the desired radiation pattern can be pre-configured. Then, after the electronic device is adjusted to a certain form factor, the radiation pattern corresponding to that form factor is adopted. For example, in a tablet form, a 180° phase difference is selected to produce a radiation pattern where the main lobe is perpendicular to the screen plane. As another example, in a tent form, a 90° phase difference is selected to make the main lobe parallel to the tabletop and radiate forward.

[0090] This embodiment applies the antenna module to electronic devices with shape changes, and the antenna module can adaptively adjust the radiation field pattern according to the shape of the electronic device.

[0091] According to another embodiment of this disclosure, the electronic device includes an antenna module and a device body, the device body including a first body and a second body rotatably connected.

[0092] Electronic devices have multiple communication modes, such as satellite communication, WWAN (Wireless Wide Area Network) communication, WLAN (Wireless Local Area Networks) communication, positioning base station mode, and search mode. When an electronic device switches to different communication modes, the control component can control the operating state of the target first phase shifter among multiple first phase shifters and / or the target second phase shifter among multiple second phase shifters, so that the radiation pattern of the antenna module adapts to the switched communication mode. For example, when the electronic device switches to WLAN communication mode, it selects a phase difference that provides relatively better omnidirectional coverage or stronger radiation in a predetermined direction.

[0093] In this embodiment, the antenna module is applied to an electronic device with a switchable communication mode. The antenna module can adaptively adjust the radiation pattern according to the communication mode of the electronic device, so that the radiation pattern is adapted to the communication mode, thereby improving the stability and performance of wireless communication.

[0094] According to another embodiment of this disclosure, the electronic device includes an antenna module and a device body, the device body including a first body and a second body rotatably connected.

[0095] The electronic device also includes a display screen having a first screen area and a second screen area. The first screen area is displayed on a first surface of the first body. The first surface can be the surface of the first body facing the second body in a folded state. The second screen area is a flexible screen and can be housed in a storage area; for example, the second screen area can be housed within the first body, rolled up around the second body, or rolled within a pivot cavity between the first and second bodies.

[0096] Electronic devices have different usage modes. For example, in a first usage mode, the second screen area is pulled out from the storage area (i.e., the first body, the second body, or the hinge cavity), and the electronic device is in a roll-out state, thus forming a larger screen with the first and second screen areas, thereby increasing the display area. In a second usage mode, the second screen area is stored back into the first body, the second body, or the hinge cavity, and the electronic device is in a roll-in state, thereby reducing the display area.

[0097] In one example, the antenna module in the electronic device can be located in the first body, and the radiation pattern of the antenna module differs in the first and second usage modes. For example, when the electronic device is in its unfolded state, a phase difference capable of forming a strong directional radiation pattern is selected, thereby enabling highly directional satellite communication via a narrow beam; while when the electronic device is in its retracted state, a radiation pattern capable of forming a strong gain in a specific direction is selected, thereby enabling WLAN communication. In another example, the antenna module in the electronic device is located at the rotatable connection between the first and second bodies, i.e., the antenna module is located in the pivot area.

[0098] According to another embodiment of this disclosure, the center-to-center distance between the first antenna and the second antenna is 1 / 2, 1 / 3, or 1 / 4 of the target frequency band wavelength. In this embodiment, the center-to-center distance between the first antenna and the second antenna is relatively small, which reduces the limitations on the installation space of the antenna module and makes it suitable for compact installation areas, thereby allowing the antenna module to be integrated into a small space such as the pivot area.

[0099] Figure 4 This is a schematic flowchart of a control method for an electronic device according to an embodiment of the present disclosure.

[0100] In this embodiment, the control method for the electronic device includes operations S410 to S420.

[0101] When operating the S410, monitor the target communication needs of electronic devices and / or environmental changes in the surrounding space environment.

[0102] Target communication requirements include, for example, signal evaluation requirements, better signal quality requirements, signal strength requirements in a certain direction, and network quality requirements for running specific applications.

[0103] Information on environmental changes includes, for example, whether the device has been moved to a new space, whether it has been moved, whether it has been held or obstructed, whether any obstructions have entered the environment, whether other devices have entered or been moved out of the environment, and changes in signal interference.

[0104] In operation of S420, the time difference of feeding the first and second antennas of the electronic device is adjusted based on the target communication requirements and / or environmental change information, so as to form a target phase difference between the first and second antennas, thereby adjusting the radiation pattern of the antenna module.

[0105] For example, by sending control commands to the control components in the electronic device, the phase shift angle of the digital phase shifter or the switching state of the fixed phase shifter can be adjusted, thereby changing the time difference between the feeding times of the first and second antennas, and adjusting the radiation pattern through this time difference.

[0106] This embodiment can adaptively adjust the feed delay of the two antennas based on the target communication requirements of the electronic device and / or the environmental changes in the space environment, and adjust the radiation pattern of the antenna module in real time, so as to improve the communication performance according to the communication requirements and the environment.

[0107] According to another embodiment of this disclosure, the control component in the electronic device includes a signal distributor and a phase shifter. During the process of regulating the time difference for feeding the feed terminals of the first and second antennas, the operating parameters of the phase shifter can be adjusted according to the target communication requirements and / or environmental changes in the surrounding space environment. This allows the RF front-end circuit to feed the first and second feed terminals respectively at the target time difference, thereby creating a target phase difference between the first and second antennas and adjusting the radiation pattern of the antenna module. The operating parameters of the phase shifter include its operating state or phase shift angle, etc.

[0108] For example, when an electronic device detects that a game application is currently running, and the built-in sensor detects that the electronic device has switched from a moving state to a stationary state, the control unit introduces a 210° phase delay into the signal fed to the second antenna by controlling a phase shifter. This creates a target phase difference of 150° between the first antenna and the second antenna, thereby shaping the antenna module into a specific radiation pattern to improve signal quality during gameplay.

[0109] This embodiment can automatically adjust the feed delay of the two antennas according to the target communication requirements and / or the environmental changes in the space environment, thereby changing the radiation pattern of the antenna module and achieving the effect of adaptively improving communication performance according to communication requirements and environmental changes.

[0110] Next, combined Figures 5-18 The simulation verification results are explained.

[0111] like Figure 5 As shown, the simulation model consists of a first antenna 511 and a second antenna 512 configured on a 200mm x 200mm grounding surface. The two antennas are symmetrical inverted F-type antennas.

[0112] like Figures 6A-6C As shown, the center-to-center distance between the two antennas is 1 / 2, 1 / 3, or 1 / 4 of the target frequency band wavelength, where λ in the figure represents the target frequency band wavelength. Figure 6A As shown, for the case where the center-to-center distance between the two antennas is 1 / 4 of the target frequency band wavelength, the minimum edge distance d1 between the two antennas is 2mm. Figure 6B As shown, for the case where the center-to-center distance between the two antennas is 1 / 3 of the target frequency band wavelength, the minimum edge distance d2 between the two antennas is 10mm. Figure 6C As shown, for the case where the center-to-center distance between the two antennas is 1 / 2 of the target frequency band wavelength, the minimum edge distance d3 between the two antennas is 30mm.

[0113] During the simulation, based on the principle of electromagnetic wave spatial interference, the phase difference between the two antennas is changed by controlling the components, causing constructive interference of electromagnetic waves in a specific direction in space, thereby creating gain enhancement in that direction. Simultaneously, by continuously adjusting the phase difference, dynamic adjustment and shape optimization of the radiation pattern can be achieved. The effectiveness of this disclosure was verified through simulation using CST software. The target frequency band wavelength is denoted as λ, and the target frequency band is 2.5 GHz or 6 GHz. The phase difference between the two antennas is adjusted in 30° steps within the range of 0~360° using simulation software.

[0114] Simulation results are as follows Figures 7-18 As shown, the details are as follows:

[0115] The center-to-center distance between the two antennas is λ / 3. When the minimum edge distance d2 between the two antennas is 10 mm, the 2.5 GHz radiation pattern adjusted for phase difference is as follows: Figure 7 and Figure 8 As shown, the results of adjusting the 6GHz radiation pattern with phase difference are as follows: Figure 9 and Figure 10 As shown. Figure 8 For example, Figure 8 The yellow line in the diagram corresponds to the "1

[30] +2[0]" mode, which indicates that the delay phase of the first antenna is 30° and the delay phase of the second antenna is 0°, with a phase difference of 30° between the two antennas. Figure 7 The second radiation field pattern in the first row. The other lines are similar, so I won't go into detail.

[0116] The center-to-center distance between the two antennas is λ / 4. When the minimum edge distance d2 between the two antennas is 10 mm, the 2.5 GHz radiation pattern adjusted for phase difference is as follows: Figure 11 and Figure 12 As shown, the results of adjusting the 6GHz radiation pattern with phase difference are as follows: Figure 13 and Figure 14 As shown.

[0117] The center-to-center distance between the two antennas is λ / 2. When the minimum edge distance d2 between the two antennas is 10 mm, the 2.5 GHz radiation pattern adjusted for phase difference is as follows: Figure 15 and Figure 16 As shown, the results of adjusting the 6GHz radiation pattern with phase difference are as follows: Figure 17 and Figure 18 As shown.

[0118] Simulation results show that when the phase difference between the two antennas changes from 0 degrees to 330 degrees in 30-degree increments, the synthesized 3D radiation pattern undergoes continuous and significant deflection and change in response to the phase difference adjustment. The adjustment effect can be quantified by comparing the 2D radiation pattern diagrams. For example, comparing the radiation pattern diagrams on the horizontal plane (H-plane)... Figure 8 , Figure 10 , Figure 12 , Figure 4 , Figure 16 and Figure 18 As shown, the horizontal radiation pattern exhibits signal blind spots at different angles due to miniaturization and the influence of the ground plane. However, these blind spots can be optimized in other modes. By connecting the maximum values ​​at each angle under different modes, a signal coverage close to that of an ideal antenna can be obtained. Therefore, the embodiments of this disclosure can achieve fine-tuning of the antenna radiation pattern, improve the antenna gain of electronic devices, and avoid signal blind spots.

[0119] Furthermore, simulation results show that the two antennas, despite having different center-to-center distances and different minimum antenna edge distances, do not affect the radiation pattern control effect. The two antennas can achieve an extremely compact layout (e.g., the minimum antenna edge distance is only 2mm), and simulation results also show that both achieve good radiation pattern control. Therefore, this embodiment does not have strict distance requirements between the two antennas, allowing for miniaturized antenna design with minimal distance, while simultaneously meeting the radiation pattern control requirements of multi-band antenna designs. It is suitable for miniaturized antenna scenarios in mobile communication devices such as laptops, tablets, and mobile phones.
