Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and specifically relates to an antenna assembly, an electronic device, and a control method for the antenna assembly. Background Technology

[0002] In related technologies, the bottom bezel of an electronic device can serve as a mid-to-high frequency antenna to receive mid-to-high frequency signals, thereby enabling communication. However, when a user holds the electronic device, the contact between the hand and the device causes the electric field energy of the mid-to-high frequency antenna located near the palm to be absorbed by the hand, resulting in a decrease in antenna performance and reduced communication efficiency in both handheld and head-and-hand positions. Summary of the Invention

[0003] This application aims to provide an antenna assembly, an electronic device, and a control method for the antenna assembly, which at least solves the problems of performance degradation and reduced communication efficiency of the antenna in handheld and head-and-hand states.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] In a first aspect, this application proposes an antenna assembly for use in electronic devices. The antenna assembly includes a first stub, a second stub, a third stub, a first feed component, a first switch, a first grounding point, a second switch, and a second grounding point. The second stub is located on a first side of the first stub, and a first gap exists between the second stub and the first stub. The third stub is located on a second side of the first stub, and a second gap exists between the third stub and the first stub. The first feed component is connected to the side of the first stub closest to the second stub. The first switch is connected to the second stub. The first grounding point is connected to the first switch. The second switch is connected to the second stub and located on the side of the first switch furthest from the first stub. The second grounding point is connected to the second switch. When the palm of a human hand is closer to the second stub than to the second and third stubs, the first switch and the second switch are turned on.

[0006] In the antenna assembly of this application, the user's palm is closer to the second segment relative to the second and third segments. When the palm is closer to the second segment, the first feeding component is connected to the side of the first segment closest to the second segment, and the first and second switches are turned on, causing the current to return to ground near the first gap in the second segment. The electric field energy coupled from the first segment to the second segment decreases, and the electric field energy of the second segment near the palm position also decreases. Consequently, the electric field energy absorbed by the palm at the second segment also decreases. Furthermore, due to the decrease in the electric field energy coupled to the second segment, the current at the first segment is directed away from the second segment. At this time, the electric field energy coupled from the first segment to the third segment increases, and the electric field energy at the third segment also increases, thereby improving the signal strength of the electronic device. When the user uses the electronic device in a handheld or head-hand position, a good working environment for the antenna assembly can be guaranteed, thereby improving the user's communication quality and providing a better communication and user experience in these two scenarios. This creates a communication selling point, enhances brand awareness, and increases product sales.

[0007] Secondly, this application proposes an electronic device including an antenna assembly and an interface as described in any of the above technical solutions, wherein the interface is disposed in the electronic device and exposed in the first branch. This electronic device possesses all the beneficial effects of the antenna assembly as described in any of the above technical solutions, which will not be elaborated further here.

[0008] Thirdly, this application proposes a control method for an antenna assembly, used in any of the above-mentioned technical solutions. The control method includes: obtaining the position of a human hand; based on the fact that the human hand is closer to the second stub than the third stub, controlling the first stub to connect to the first feed component; and controlling the first switch and the second switch to be turned on so that the second stub is grounded through the first switch and the second switch. This control method for the antenna assembly has all the beneficial effects of the antenna assembly in any of the above-mentioned technical solutions, which will not be elaborated here.

[0025] The following is combined Figures 1 to 8 This application describes antenna assemblies, electronic devices, control methods and apparatus, and readable storage media according to embodiments thereof.

[0026] like Figure 1 and Figure 2As shown, an antenna assembly 100 according to some embodiments of this application is used in an electronic device. The antenna assembly 100 includes a first stub 102, a second stub 104, a third stub 106, a first feed component 108, a first switch 110, a first ground point 112, a second switch 114, and a second ground point 116. The second stub 104 is located on a first side of the first stub 102, and a first gap 138 is formed between the second stub 104 and the first stub 102. The third stub 106 is located on a second side of the first stub 102, and a first gap 138 is formed between the third stub 106 and the first stub 102. It has a second gap 140; a first power supply component 108 is connected to the side of the first branch 102 near the second branch 104; a first switch 110 is connected to the second branch 104; a first grounding point 112 is connected to the first switch 110; a second switch 114 is connected to the second branch 104 and is located on the side of the first switch 110 away from the first branch 102; a second grounding point 116 is connected to the second switch 114; wherein, when the palm of the human hand is closer to the second branch 104 than the second branch 104 and the third branch 106, the first switch 110 and the second switch 114 are turned on.

[0027] like Figure 1 and Figure 2As shown, an antenna assembly 100 according to an embodiment of this application is used in an electronic device. The antenna assembly 100 includes a first stub 102, a second stub 104, a third stub 106, a first feed component 108, a first switch 110, a first grounding point 112, a second switch 114, and a second grounding point 116. The first stub 102, the second stub 104, and the third stub 106 are all antenna structures used to generate resonance, thereby enhancing the radiation of radio signals and improving communication quality. The second stub 104 is disposed on a first side of the first stub 102, and a first gap 138 is provided between the second stub 104 and the first stub 102. Transmission occurs between the first stub 102 and the second stub 104 via electric field coupling. The third branch 106 is located on the second side of the first branch 102. There is a second gap 140 between the third branch 106 and the first branch 102. A series device for changing the coupling strength of the gap is provided at the second gap 140, which can allow current to pass through the electric field at the second gap 140 and be transmitted between the first branch 102 and the third branch 106 through electric field coupling. The first feed component 108 is connected to the side of the first stub 102 closest to the second stub 104 for signal transmission. Since the first stub 102 is connected to the first feed component 108, and the first stub 102 is connected in series with the second stub 104 and the third stub 106, the first stub 102, the second stub 104, and the third stub 106 together form a medium-high frequency antenna (MHB). The first switch 110 is connected to the second stub 104, and the first ground point 112 is connected to the first switch 110. The first switch 110 is used to control whether the current returns to ground at the first ground point 112. The second switch 114 is connected to the second stub 104, and the second switch 114 is located on the side of the first switch 110 away from the first stub 102. The second ground point 116 is connected to the second switch 114, and is used to control the current to return to ground at the second switch 114 through the second ground point 116.The user's palm is closer to the second branch 104 relative to the second and third branches 106. When the palm is closer to the second branch 104, the first power supply component 108 is connected to the side of the first branch 102 closest to the second branch 104. The first switch 110 and the second switch 114 are turned on, causing the current to return to ground near the first gap 138 in the second branch 104. The electric field energy coupled from the first branch 102 to the second branch 104 is reduced, and the electric field energy in the second branch 104 near the palm is also reduced, thus being absorbed by the palm at the second branch 104. The electric field energy also decreases accordingly; and because the electric field energy coupled to the second branch 104 decreases, the current at the first branch 102 is directed away from the second branch 104. At this time, the electric field energy coupled from the first branch 102 to the third branch 106 increases, and the electric field energy at the third branch 106 increases, thereby improving the signal strength of the electronic device. When the user uses the electronic device in a handheld or head-and-hand position, the antenna assembly 100 can also be guaranteed to have a good working environment, thereby improving the user's communication quality, allowing the user to have a better communication and user experience in these two scenarios, creating communication selling points, and enhancing brand awareness and product sales.

[0028] Furthermore, a series device for changing the coupling strength of the gap is provided at the first gap 138, which can allow current to pass through the electric field at the first gap 138.

[0029] Furthermore, the first switch 110 and the second switch 114 are switched on by switching zero-ohm or low-resistance reactive devices.

[0030] Furthermore, the first switch 110 and the second switch 114, by tuning the bandpass (LC, Inductor Capacitor) of a specific frequency band, allow waves of that specific frequency band to pass through the device while shielding other frequency bands, thereby enabling the first switch 110 and the second switch 114 to conduct.

[0031] Furthermore, the first power supply component 108 is used to achieve power supply in the mid-to-high frequency band.

[0032] Furthermore, the first branch 102 and the first switch 110 can be connected by a ground connection or a bandpass connection of a specific frequency band.

[0033] Furthermore, the second branch 104 and the third branch 106 are symmetrically arranged relative to the first branch 102, which can also be applied to the left-handed mode. Specifically, in the right-handed mode, the first feeding component 108 mainly operates in a common-mode mode from the first branch 102 to the second slot 140 and from the second slot 140 to the third branch 106. At this time, the reduction of radio signal in the right-handed and right-head-handed usage scenarios is greatly improved, avoiding the large absorption of mid-to-high frequency antenna energy due to the zero-distance contact between the palm and the bottom of the electronic device, reducing the reduction of antenna performance in the handheld and head-handed states, and thus improving the user's communication experience in these two scenarios.

[0034] Specifically, the first branch 102 is used to collect hand grip data and transmit the hand grip data to the integrated system to determine the grip mode.

[0035] Specifically, the antenna assembly 100 in this embodiment can also be applied to cellular or other frequency bands such as low frequency, N78, N79 and wireless communication (WiFi, Wireless Fidelity).

[0036] Specifically, such as Figure 1 and Figure 2 As shown, the first side of the first branch 102 is A.

[0037] Specifically, such as Figure 1 and Figure 2 As shown, the second side of the first branch 102 is B.

[0038] Specifically, such as Figure 1 and Figure 2 As shown, the side of the first branch 102 closest to the second branch 104 is the first side of the first branch 102.

[0039] Specifically, such as Figure 1 and Figure 2 As shown, the side of the first switch 110 away from the first branch 102 is C.

[0040] Specifically, such as Figure 3 and Figure 4 As shown, the white areas represent regions with stronger electric field energy, and the black areas represent regions with weaker electric field energy. Figure 3 This is a comparative example of the back-view electric field diagram of an antenna assembly, i.e. Figure 3 The image shows the back-view electric field diagram of the antenna assembly in a left-hand holding state when the embodiments of this application are not adopted. Figure 3 As can be seen, the white area on the right side, near the palm of the left hand, is larger, indicating a stronger electric field energy in that area. Figure 4 This is a back-view electric field diagram of the antenna assembly in the left-hand holding state in this embodiment of the application. Figure 4As can be seen, the white area on the right side near the left palm is smaller, indicating that the electric field energy is greatly suppressed there. After the electric field is guided to the area on the left side where the left hand absorbs less, the white area on the left side away from the left palm is larger, indicating that the electric field energy is stronger there.

[0041] like Figure 1 As shown, according to some embodiments of this application, the antenna assembly 100 further includes a third switch 118 and a third grounding point 120. The third switch 118 is connected to the side of the first stub 102 near the third stub 106; the third grounding point 120 is connected to the third switch 118; wherein, when the palm of a human hand is closer to the third stub 106 than the second stub 104 and the third stub 106, the third switch 118 is turned on.

[0042] like Figure 1 As shown, in this embodiment, the antenna assembly 100 further includes a third switch 118 and a third grounding point 120. The third switch 118 is connected to the side of the first stub 102 closest to the third stub 106, and the third grounding point 120 is connected to the third switch 118. This allows current to return to ground through the third grounding point 120 after the third switch 118 is turned on, preventing current from flowing through the third stub 106. In left-handed mode, the user's palm is closer to the third stub 106 than the second stub 104. When the first stub 102 detects that it is currently in left-handed mode, the third switch 118 is turned on, allowing current to return to ground at the third grounding point 120. This reduces the electric field energy coupled from the first stub 102 to the third stub 106. The electric field energy of the stub 106 near the palm position decreases, thus reducing the electric field energy absorbed by the palm at the third stub 106. Furthermore, due to the reduced electric field energy coupled to the third stub 106, the current at the first stub 102 is directed away from the third stub 106. This increases the electric field energy coupled from the first stub 102 to the second stub 104. This increased electric field energy at the second stub 104 enhances the signal strength of the electronic device. Even when the user uses the electronic device in a handheld or head-and-hand position, a good working environment for the antenna assembly 100 is ensured, thereby improving the user's communication quality and providing a superior communication and user experience in these two scenarios. This creates a communication selling point, enhances brand awareness, and boosts product sales.

[0043] Furthermore, the second switch 114 presents a strong current return to ground through a zero-ohm or low-resistance reactive device to form a slot differential mode resonance between the first stub 102 and the second stub 104. At the same time, the first switch 110 switches different capacitive inductance values ​​and tunes the differential mode resonance to the upper limit of the operating frequency band, thereby further increasing the electric field energy coupled from the first stub 102 to the second stub 104, so as to further enhance the transmission effect of radio signals.

[0044] Specifically, in left-hand mode, the first power supply component 108 mainly operates in a common-mode mode from the first branch 102 to the first gap 138 and from the first gap 138 to the second branch 104. At this time, the reduction of radio signal in left-hand and left-head-hand usage scenarios is greatly improved, enhancing the user's communication experience in these two scenarios.

[0045] Specifically, based on the statistical comparison of the results presented by the antenna assembly 100 in this embodiment with related schemes, the reduction in power for the left head-and-hand scenario of the mid-to-high frequency antenna decreased from 8-8.5 dB to 6-6.5 dB, an improvement of about 2 dB; the reduction in power for the right head-and-hand scenario decreased from 6-6.5 dB to 5-5.5 dB, an improvement of 1 dB. Combined with the 24.5 dBm (dBm) conducted power of the mid-frequency antenna (MB), the total radiated power (TRP) in the left head-and-hand scenario can be guaranteed to be above 15 dBm, which can handle the transmission of the entire device in the head-and-hand scenario, leaving more flexibility for the design of other antennas; the reduction in power for the left head-and-hand scenario of the mid-to-high frequency antenna decreased from 7 dB to 5.5 dB, an improvement of 1.5 dB; and the reduction in power for the right head-and-hand scenario decreased from 5.5 dB to 4.5 dB, an improvement of 1 dB. From the specific data, this embodiment improves the reduction of mid-to-high frequency antennas in both handheld and head-and-hand states, enhancing the user's communication experience while providing more flexibility in the overall design.

[0046] Specifically, such as Figure 1 and Figure 2 As shown, the side of the first branch 102 closest to the third branch 106 is the second side of the first branch 102.

[0047] Specifically, such as Figure 3 and Figure 4 As shown, the white areas represent regions with stronger electric field energy, and the black areas represent regions with weaker electric field energy. Figure 3 This is a comparative example of the back-view electric field diagram of an antenna assembly, i.e. Figure 3 The image shows the back-view electric field diagram of the antenna assembly in a left-hand holding state when the embodiments of this application are not adopted. Figure 3 As can be seen, the white area on the right side, near the palm of the left hand, is larger, indicating a stronger electric field energy in that area. Figure 4 This is a back-view electric field diagram of the antenna assembly in the left-hand holding state in this embodiment of the application. Figure 4 As can be seen, the white area on the right side near the left palm is smaller, indicating that the electric field energy is greatly suppressed there. After the electric field is guided to the area on the left side where the left hand absorbs less, the white area on the left side away from the left palm is larger, indicating that the electric field energy is stronger there.

[0048] Specifically, such as Figure 5 As shown, the electric field shifts in the direction indicated by the arrow.

[0049] like Figure 2 As shown, according to some embodiments of this application, the antenna assembly 100 further includes a fourth switch 122, a fifth switch 124, and a second power supply component 126. The first power supply component 108 is connected to the first stub 102 via the fourth switch 122; the fifth switch 124 is connected to the side of the first stub 102 near the third stub 106; and the second power supply component 126 is connected to the fifth switch 124. When the palm of a human hand is closer to the third stub 106 than the second stub 104 and the third stub 106, the fourth switch 122 is turned off, and the fifth switch 124 is turned on.

[0050] like Figure 2 As shown, in this embodiment, the antenna assembly 100 further includes a fourth switch 122, a fifth switch 124, and a second power supply component 126. The first power supply component 108 is connected to the first stub 102 through the fourth switch 122. The fourth switch 122 is used to switch the power supply to the first power supply component 108 on and off, so as to control the current flow to the first stub 102. The fifth switch 124 is connected to the side of the first branch 102 closest to the third branch 106. The second power supply component 126 is connected to the fifth switch 124. The fifth switch 124 is used to switch the power supply to the second power supply component 126 to control the current flow to the first branch 102. When the integrated system detects that the user's palm is closer to the third branch 106 than the second branch 104 and the third branch 106, it determines that it is in left-hand mode, and then opens the fourth switch 122, turning on the fifth switch 124. At this time, the second power supply component 126 is powered, the first power supply component 108 is opened, the electric field energy coupled from the first branch 102 to the third branch 106 is reduced, and the third branch 106 is located in the palm position. The electric field energy near the device decreases, thus reducing the electric field energy absorbed by the palm at the third stub 106. Furthermore, due to the reduced electric field energy coupled to the third stub 106, the current at the first stub 102 is directed away from the third stub 106. This increases the electric field energy coupled from the first stub 102 to the second stub 104, further enhancing the signal strength of the electronic device. This ensures a good working environment for the antenna assembly 100 when the user uses the electronic device in a handheld or head-and-hand position, thereby improving communication quality and providing a superior communication and user experience in these scenarios. This also creates a communication selling point, increasing brand awareness and product sales.

[0051] Furthermore, the second branch 104 and the third branch 106 are symmetrically arranged relative to the first branch 102, which can also be applied to the right-hand mode. When the integrated system detects that the user's palm is closer to the second branch 104 relative to the second branch 104 and the third branch 106, it determines that it is the right-hand mode, and then disconnects the fifth switch 124 and turns on the fourth switch 122. At this time, the first power supply component 108 supplies power and the second power supply component 126 is disconnected. At this time, the electric field energy coupled from the first branch 102 to the third branch 106 increases, causing the current to move away from the right palm position, enhancing the electric field energy at the third branch 106, thereby enhancing the transmission effect of the radio signal and reducing power loss.

[0052] Specifically, in this embodiment, the final results are statistically compared with related schemes, which can improve the reduction in handheld state to 4.5 dB and the reduction in head-and-hand state to 5.5 dB, which greatly improves the reduction in handheld and head-and-hand states of the low-frequency antenna and enhances the user's communication experience.

[0053] Specifically, such as Figure 3 and Figure 4 As shown, the white areas represent regions with stronger electric field energy, and the black areas represent regions with weaker electric field energy. Figure 3 This is a comparative example of the back-view electric field diagram of an antenna assembly, i.e. Figure 3 The image shows the back-view electric field diagram of the antenna assembly in a left-hand holding state when the embodiments of this application are not adopted. Figure 3 As can be seen, the white area on the right side, near the palm of the left hand, is larger, indicating a stronger electric field energy in that area. Figure 4 This is a back-view electric field diagram of the antenna assembly in the left-hand holding state in this embodiment of the application. Figure 4 As can be seen, the white area on the right side near the left palm is smaller, indicating that the electric field energy is greatly suppressed there. After the electric field is guided to the area on the left side where the left hand absorbs less, the white area on the left side away from the left palm is larger, indicating that the electric field energy is stronger there.

[0054] Specifically, such as Figure 5 As shown, the electric field shifts in the direction indicated by the arrow.

[0055] like Figure 1 As shown, according to some embodiments of this application, the antenna assembly 100 further includes a third feed component 128, which is connected to the side of the second stub 104 away from the first stub 102.

[0056] like Figure 1 As shown, in this embodiment, the antenna assembly 100 further includes a third feed component 128, which is connected to the second stub 104 and located on the side of the second stub 104 away from the first stub 102, so as to transmit signals.

[0057] Furthermore, the third feeding component 128 is used to feed the low-frequency antenna.

[0058] Furthermore, in left-hand mode, the three-quarter wavelength inverted F antenna mode (IFA) of the third feed component 128 to the first switch 110 is tuned and resonated to the upper limit of the operating frequency band, thereby further increasing the electric field energy coupled from the first stub 102 to the second stub 104, so as to further enhance the transmission effect of radio signals.

[0059] Specifically, such as Figure 1 and Figure 2 As shown, the side of the second branch 104 that is away from the first branch 102 is D.

[0060] Specifically, such as Figure 3 and Figure 4 As shown, the white areas represent regions with stronger electric field energy, and the black areas represent regions with weaker electric field energy. Figure 3 This is a comparative example of the back-view electric field diagram of an antenna assembly, i.e. Figure 3 The image shows the back-view electric field diagram of the antenna assembly in a left-hand holding state when the embodiments of this application are not adopted. Figure 3 As can be seen, the white area on the right side, near the palm of the left hand, is larger, indicating a stronger electric field energy in that area. Figure 4 This is a back-view electric field diagram of the antenna assembly in the left-hand holding state in this embodiment of the application. Figure 4 As can be seen, the white area on the right side near the left palm is smaller, indicating that the electric field energy is greatly suppressed there. After the electric field is guided to the area on the left side where the left hand absorbs less, the white area on the left side away from the left palm is larger, indicating that the electric field energy is stronger there.

[0061] like Figure 1 and Figure 2 As shown, according to some embodiments of this application, the antenna assembly 100 further includes a sixth switch 130, a sixth grounding point 132, a seventh switch 134, and a seventh grounding point 136. The sixth switch 130 is connected to the side of the third stub 106 near the first stub 102; the sixth grounding point 132 is connected to the sixth switch 130; the seventh switch 134 is connected to the third stub 106 and is located on the side of the sixth switch 130 away from the first stub 102; and the seventh grounding point 136 is connected to the seventh switch 134.

[0062] like Figure 1 and Figure 2As shown, in this embodiment, the antenna assembly 100 further includes a sixth switch 130, a sixth grounding point 132, a seventh switch 134, and a seventh grounding point 136. The sixth switch 130 is connected to the side of the third stub 106 closest to the first stub 102, and the sixth grounding point 132 is connected to the sixth switch 130 to control whether the current returns to ground at the sixth grounding point 132. The seventh switch 134 is connected to the third stub 106 and is located on the side of the sixth switch 130 away from the first stub 102. The seventh grounding point 136 is connected to the seventh switch 134 to control whether the current returns to ground at the seventh grounding point 136 and to control whether the electric field energy is coupled from the first stub 102 to the third stub 106.

[0063] Specifically, such as Figure 1 and Figure 2 As shown, the side of the third branch 106 closest to the first branch 102 is E.

[0064] Specifically, such as Figure 1 and Figure 2 As shown, the side of the sixth switch 130 furthest from the first branch 102 is F.

[0065] An electronic device according to some embodiments of this application includes an antenna assembly and an interface 150 as described in any of the above embodiments, the interface 150 being disposed in the electronic device and exposed at the first branch 102.

[0066] In this embodiment, the electronic device includes an antenna assembly as described in any of the above embodiments, and also includes an interface 150. The interface 150 is disposed in the electronic device so that the electronic device can connect to other devices through the interface 150, thereby realizing data transmission.

[0067] Specifically, the interface can be a USB-A interface, a USB-C interface, or a Lightning interface, etc.

[0068] An electronic device according to some embodiments of this application further includes an electromagnetic wave absorption ratio sensor 151 (Sarsensor) and a gravity sensor 152 (G-sensor, Gravity-sensor). The electromagnetic wave absorption ratio sensor 151 is used to detect the capacitance value at the first branch 102; the gravity sensor 152 is used to detect the posture of the electronic device; the electronic device is used to obtain the position of a human hand based on the capacitance value at the first branch 102 and the posture of the electronic device.

[0069] In this embodiment, the electronic device also includes an electromagnetic wave absorption ratio sensor 151 and a gravity sensor 152. The electromagnetic wave absorption ratio sensor 151 is used to detect the capacitance value at the first branch 102 and transmit the detection data to the integrated system to determine which branch the palm is in contact with. The gravity sensor 152 is used to detect the posture of the electronic device, detect and collect posture data such as the longitudinal tilt angle or lateral tilt angle between the electronic device and the horizontal plane, and transmit the detection data to the integrated system. The integrated system of the electronic device is used to obtain the position of the human hand based on the capacitance value at the first branch 102 and the posture data of the electronic device to determine the left and right head and hand scenario in which the electronic device is located.

[0070] Furthermore, the electromagnetic wave absorption ratio sensor 151 detects different capacitance values ​​at the first branch 102 to determine whether there is a hand holding the scene or a human body is close to it, and then determines to call up the preset scene to reduce the electromagnetic wave absorption ratio.

[0071] Electronic devices can also intelligently determine left and right head / hand scenarios by combining the electromagnetic wave absorption ratio sensor 151 and gravity sensor 152 with the earpiece, under-screen distance sensor and specific application software scenarios. This scenario recognition can be continuously improved through large-scale user and artificial intelligence algorithm evolution, enabling electronic devices to make more accurate determinations of left and right head / hand scenarios.

[0072] Electronic devices use multiplexed electromagnetic wave absorption ratio sensors, combined with gravity sensors, to determine whether the device is in a handheld or head-and-hand scenario (for head-and-hand scenarios, further testing is needed using under-display photosensitive sensors, the contact area of ​​the screen, and software usage scenarios).

[0073] like Figure 6 As shown, a control method for an antenna assembly according to some embodiments of this application is used for an antenna assembly as described in any of the above embodiments. The control method for the antenna assembly includes:

[0074] Step 602: Obtain the position of the human hand;

[0075] Step 604: Based on the fact that the human hand is closer to the second segment than the third segment, control the connection between the first segment and the first power supply component.

[0076] Step 606: Control the first switch and the second switch to turn on so that the second branch is grounded through the first switch and the second switch.

[0077] like Figure 6As shown, in this embodiment, the antenna assembly control method is used to control the antenna assembly as described in any of the above embodiments. First, the position of the human hand is obtained. When the human hand is closer to the second segment relative to the second and third segments, the first segment is connected to the first feed component to transmit signals. Then, the first and second switches are turned on, grounding the second segment through the first and second switches. By turning on the first and second switches, current returns to ground near the first gap in the second segment. The electric field energy coupled from the first segment to the second segment is reduced, and the electric field energy in the second segment near the palm position is decreased. This reduces the amount of electric field energy absorbed by the palm at the second branch; and because the electric field energy coupled to the second branch decreases, the current at the first branch is diverted away from the second branch. At this time, the electric field energy coupled from the first branch to the third branch increases. The increased electric field energy at the third branch can improve the signal strength of the electronic device. When the user uses the electronic device in a handheld or head-hand position, it can also ensure a good working environment for the antenna components, thereby improving the user's communication quality, giving the user a better communication and user experience in these two scenarios, creating a communication selling point, and enhancing brand awareness and product sales.

[0078] A control method for an antenna assembly according to some embodiments of this application, after controlling the first switch and the second switch to be turned on, further includes:

[0079] The third switch controlling the antenna assembly is disconnected;

[0080] The capacitive inductance value of the sixth switch of the control antenna assembly is adjusted to a first threshold range so that the differential mode resonant frequency of the first stub and the second stub is greater than the upper limit of the operating frequency range of the antenna assembly.

[0081] The seventh switch of the control antenna assembly is turned on so that the third stub is grounded through the seventh switch.

[0082] In this embodiment, after the first and second switches are turned on, the control method for the antenna assembly further includes turning off the third switch of the antenna assembly to guide electric field energy coupling from the first stub to the third stub. The capacitive inductance value of the sixth switch of the antenna assembly is adjusted to a first threshold range so that the differential-mode resonant frequency of the first and second stubs is greater than the upper limit of the operating frequency range of the antenna assembly, which can further draw current to the third stub. The seventh switch of the antenna assembly is turned on so that the third stub is grounded through the seventh switch. By keeping the third switch open, the sixth and seventh switches switch appropriately according to the structural characteristics and operating frequency band on the right, allowing electric field energy to couple from the first stub to the third stub. The seventh switch is connected to a zero-ohm or low-resistance reactive device to create a strong current return to ground, forming a slot differential mode resonance between the first and third stubs. Simultaneously, the sixth switch switches different capacitive values ​​to tune the differential mode resonance to the upper limit of the operating frequency band, further guiding electric field energy to couple to the third stub. This keeps the current away from the palm position, further enhancing the energy in the wires at the third stub, thereby improving the transmission effect of the radio signal, reducing power loss, and reducing the signal drop of the mid-to-high frequency band antenna in handheld and head-held states when the user is holding the electronic device. By coupling electric field energy from the first stub to the third stub, the signal strength of the electronic device is improved. Even when the user is holding or using the electronic device in a head-held state, a good working environment for the antenna components is guaranteed, improving the user's communication quality and providing a better communication and user experience in these two scenarios. This creates a communication selling point, enhances brand awareness, and increases product sales.

[0083] A method for controlling an antenna assembly according to some embodiments of this application further includes:

[0084] When the palm of the human hand is closer to the third segment than the second and third segments, the first segment is connected to the first power supply component.

[0085] The third switch of the control antenna assembly is turned on so that the first stub is grounded through the third switch;

[0086] The seventh switch of the control antenna assembly is turned on so that the third stub is grounded through the seventh switch.

[0087] In this embodiment, by first obtaining the position of the human hand, when the human hand is closer to the third branch relative to the second and third branches, the integrated system determines that it is in left-hand mode and controls the first branch to connect to the first feeding component. At the same time, it controls the third switch of the antenna assembly to be turned on so that the first branch is grounded through the third switch, guiding the current to the second branch. It then controls the seventh switch of the antenna assembly to be turned on so that the third branch is grounded through the seventh switch, preventing the electric field energy from coupling with the third branch. The third and seventh switches switch between zero-ohm or low-resistance reactive devices or set the bandpass of a specific frequency band, allowing the current to return to ground on the right side of the first stub. This significantly reduces the electric field energy coupled to the third stub through the electric field of the second gap, while simultaneously directing the current to the second stub away from the left palm. This reduces the signal drop of the mid-to-high frequency antenna in handheld and head-held states when the user holds the electronic device, and directs the current at the first stub away from the palm, thereby improving the signal strength of the electronic device. This ensures a good working environment for the antenna components when the user uses the electronic device in handheld or head-held states, thus improving the user's communication quality and providing a better communication and user experience in these two scenarios. This also creates a communication selling point, enhances brand awareness, and increases product sales.

[0088] Specifically, based on the statistical comparison of the antenna component control method in this embodiment with related schemes, the reduction in power for the left head-and-hand scenario of the mid-to-high frequency antenna decreased from 8-8.5 dB to 6-6.5 dB, an improvement of approximately 2 dB; the reduction in power for the right head-and-hand scenario decreased from 6-6.5 dB to 5-5.5 dB, an improvement of 1 dB. Combined with the 24.5 dBmW conducted power of the mid-frequency antenna, the omnidirectional radiation power in the head-and-hand scenario can be guaranteed to be above 15 dBmW, which can handle the overall head-and-hand scenario transmission and leave more flexibility for the design of other antennas. The reduction in power for the left hand scenario of the mid-to-high frequency antenna decreased from 7 dB to 5.5 dB, an improvement of 1.5 dB; and the reduction in power for the right hand scenario decreased from 5.5 dB to 4.5 dB, an improvement of 1 dB. From the specific data, this embodiment improves the power reduction of the mid-to-high frequency antenna in both handheld and head-and-hand scenarios, enhancing the user's communication experience while providing more flexibility in the overall device design.

[0089] According to some embodiments of this application, a control method for an antenna assembly further includes, after turning on the seventh switch of the antenna assembly:

[0090] Turn on the second switch to ground the second branch through the second switch;

[0091] The capacitance value of the first switch is adjusted to a second threshold range so that the differential mode resonant frequency of the first stub and the second stub is greater than the upper limit of the operating frequency range of the antenna assembly.

[0092] In this embodiment, after the seventh switch of the control antenna assembly is turned on, the control method of the antenna assembly further includes turning on the second switch so that the second branch is grounded through the second switch, thereby presenting a strong current return to ground between the second switch and the third switch and forming a slot differential mode resonance. The capacitive inductance value of the first switch is adjusted to the range of the second threshold so that the differential mode resonance frequency of the first branch and the second branch is greater than the upper limit of the operating frequency range of the antenna assembly, thereby further guiding the current away from the palm to further enhance the transmission effect of radio signals. When the user holds the electronic device, by reducing the amplitude of the mid-to-high frequency band antenna in the handheld and head-and-hand states, and guiding the current away from the palm, the electric field energy is coupled from the first branch to the second branch. This ensures a good working environment for the antenna assembly even when the electronic device is held by the user, improves the user's communication quality, and provides the user with a better communication and user experience in these two scenarios. It also creates a communication selling point, enhances brand awareness and product sales.

[0093] Furthermore, a zero-ohm or low-resistance reactive device needs to be connected at the second switch to form a slot differential mode resonance between the second and third switches, presenting a strong current return. The first switch switches different capacitive inductance values ​​to tune the differential mode resonance to a later operating frequency band, thereby further guiding the current away from the left palm, allowing the electric field energy to couple from the first stub to the second stub, thus improving the signal strength of the electronic device. When the user uses the electronic device in a handheld or head-and-hand position, a good working environment for the antenna assembly can be guaranteed, thereby improving the user's communication quality and giving the user a better communication and user experience in these two scenarios. This also creates a communication selling point, enhances brand awareness, and increases product sales.

[0094] Furthermore, the second switch switches zero-ohm or low-resistance reactive devices to form a strong current return, creating a slot differential mode resonance between the second and fifth switches. The first switch switches different capacitive inductance values ​​to tune the differential mode resonance to the power frequency band, thereby further guiding the current away from the left palm, allowing the electric field energy to couple from the first stub to the second stub, thus improving the signal strength of the electronic device. When the user uses the electronic device in a handheld or head-and-hand position, a good working environment for the antenna components can be guaranteed, thereby improving the user's communication quality and providing a better communication and user experience in these two scenarios. This creates a communication selling point, enhances brand awareness, and increases product sales.

[0095] According to some embodiments of this application, a control method for an antenna assembly further includes, after turning on the seventh switch of the antenna assembly:

[0096] The second stub between the third feed component of the control antenna assembly and the first switch is tuned to a three-quarter wavelength inverted F antenna mode so that the differential mode resonant frequency of the first stub and the second stub is greater than the upper limit of the operating frequency range of the antenna assembly.

[0097] In this embodiment, after the seventh switch of the control antenna assembly is turned on, the second stub between the third feed component of the control antenna assembly and the first switch is tuned to a three-quarter wavelength inverted F antenna mode. This makes the differential mode resonant frequency of the first and second stubs greater than the upper limit of the operating frequency range of the antenna assembly, thereby further drawing the bottom current to the second stub and coupling the electric field energy from the first stub to the second stub. This improves the signal strength of the electronic device, ensuring a good working environment for the antenna assembly when the user uses the electronic device in a handheld or head-and-hand position. This enhances the user's communication quality, providing a better communication and user experience in these two scenarios, creating a communication selling point, and increasing brand awareness and product sales.

[0098] Furthermore, the second and first switches are controlled to tune the inverted F antenna mode of the second stub at three-quarter wavelength and resonate to the upper limit of the operating frequency range, so as to further pull the bottom current to the second stub, so that the electric field energy is coupled from the first stub to the second stub.

[0099] Furthermore, by switching the first switch to a zero-ohm or low-resistance reactive device, the first switch is grounded to the left to form a half-wavelength loop antenna mode. The second stub switch is switched to tune the loop antenna frequency to the upper limit of the operating frequency range, so as to further pull the bottom current to the second stub, so that the electric field energy is coupled from the first stub to the second stub, thereby improving the signal strength of the electronic device. When the user uses the electronic device in a handheld or head-and-hand position, the antenna component can also be guaranteed to have a good working environment, thereby improving the user's communication quality and giving the user a better communication and user experience in these two scenarios. This creates a communication selling point and enhances brand awareness and product sales.

[0100] According to some embodiments of this application, a control method for an antenna assembly further includes, after controlling the first switch and the second switch to be turned on, the control method for the antenna assembly includes:

[0101] The fifth switch controlling the antenna assembly is open;

[0102] The capacitive inductance values ​​of the sixth and seventh switches of the antenna assembly are adjusted to within the first threshold range so that the differential mode resonant frequency of the first and second stubs is greater than the upper limit of the operating frequency range of the antenna assembly.

[0103] In this embodiment, after controlling the first and second switches to be turned on, the fifth switch of the antenna assembly is then turned off to prevent current from returning to ground at the fifth switch. Simultaneously, the capacitive inductance values ​​of the sixth and seventh switches of the antenna assembly are adjusted to within the first threshold range so that the differential-mode resonant frequency of the first and second stubs is greater than the upper limit of the operating frequency range of the antenna assembly. This further guides the current away from the right palm, thereby enhancing the transmission effect of the radio signal. When the user holds the electronic device, the signal strength of the electronic device is improved by reducing the amplitude of the mid-to-high frequency band antenna in handheld and head-handed states, and guiding the current at the first stub away from the palm. This allows the electric field energy to couple from the first stub to the third stub. This ensures a good working environment for the antenna assembly when the user uses the electronic device in handheld or head-handed states, thereby improving the user's communication quality and providing a better communication and user experience in these two scenarios. This also creates a communication selling point, enhances brand awareness, and increases product sales.

[0104] Furthermore, the seventh switch switches zero-ohm or low-resistance reactance devices to form a strong current return to ground, creating a slot differential mode resonance between the fourth and seventh switches. The sixth switch switches different capacitive inductance values ​​to tune the differential mode resonance to the upper limit of the operating frequency range, thereby further guiding the current flow to the third branch to further enhance the transmission effect of radio signals.

[0105] Furthermore, the sixth switch to the seventh switch to the third stub is tuned to the three-quarter wavelength inverted F antenna mode and resonates to the upper limit of the operating frequency range, thereby further guiding the current flow to the third stub to further enhance the transmission effect of the radio signal.

[0106] Furthermore, the sixth switch switches to a zero-ohm or low-impedance reactive device, and the sixth switch returns to the third stub to form a half-wavelength loop antenna mode. The seventh switch switches the capacitive inductance value to tune the loop antenna frequency to the upper limit of the operating frequency range, thereby further guiding the current flow to the third stub to further enhance the transmission effect of radio signals.

[0107] A method for controlling an antenna assembly according to some embodiments of this application further includes:

[0108] When the human hand is closer to the third segment than the second and third segments, the fifth switch of the control antenna assembly is turned on so that the first segment is connected to the second feed component of the antenna assembly.

[0109] The fourth switch controlling the antenna assembly is open;

[0110] The sixth switch of the control antenna assembly is turned on so that the third stub is grounded through the sixth switch;

[0111] The seventh switch of the control antenna assembly is turned on so that the third stub is grounded through the seventh switch.

[0112] In this embodiment, the control method for the antenna assembly further includes, when the human hand is closer to the third segment relative to the second and third segments, the integrated system determines that it is in left-hand mode. Simultaneously, it controls the fifth switch of the antenna assembly to be turned on, connecting the first segment to the second feed component of the antenna assembly, allowing the second feed component to transmit signals. Then, it controls the fourth switch of the antenna assembly to be turned off, and controls the sixth switch of the antenna assembly to be turned on, grounding the third segment through the sixth switch to prevent current from passing through the third segment. Finally, it controls the seventh switch of the antenna assembly to be turned on, grounding the third segment through the seventh switch, thereby guiding the current to the second segment. In left-hand mode, at this time... When the mid-to-high frequency band feed is switched to the second feed component and the fourth switch is turned off, more current flows from the first stub to the second stub. The sixth and seventh switches switch the zero-ohm or low-impedance reactive devices or the bandpass of a specific frequency band of the operating frequency band, which can suppress the distribution of current to the third stub and allow electric field energy to couple from the first stub to the second stub, thereby improving the signal strength of the electronic device. When the user uses the electronic device in a handheld or head-and-hand position, it can also ensure a good working environment for the antenna components, thereby improving the user's communication quality and giving the user a better communication and user experience in these two scenarios. This creates a communication selling point and enhances brand awareness and product sales.

[0113] Specifically, by statistically comparing the results of the antenna component control method in this embodiment with related schemes, the reduction in noise level in handheld mode can be improved to 4.5 dB, and the reduction in noise level in head-and-hand mode can be improved to 5.5 dB. This significantly improves the reduction in noise level in both handheld and head-and-hand modes of the low-frequency antenna, thereby enhancing the user's communication experience.

[0114] According to some embodiments of this application, a method for controlling an antenna assembly, including obtaining the position of a human hand's palm, includes:

[0115] The electromagnetic wave absorption ratio sensor controls the electronic equipment to detect the capacitance value at the first branch.

[0116] Gravity sensors control the attitude of electronic devices.

[0117] The position of the human hand is determined based on the capacitance value at the first segment, the posture of the electronic device, and the working area of ​​the screen of the electronic device.

[0118] In this embodiment, the electromagnetic wave absorption ratio sensor of the control electronic device detects the capacitance value at the first branch and transmits the detected data to the integrated system. The gravity sensor of the control electronic device detects the posture of the electronic device and transmits the data to the integrated system. The integrated system obtains the position of the human hand by using the capacitance value at the first branch, the posture data of the electronic device, and the working area of ​​the screen of the electronic device. The integrated system combines the capacitance value at the first branch, the posture data of the electronic device, and the working area of ​​the screen of the electronic device with the earpiece, the under-screen distance sensor, and the specific application software scenario to intelligently determine the left and right head and hand scenarios. This scenario recognition can be continuously improved through large-scale user and artificial intelligence algorithm evolution.
