Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and more particularly to an electronic device, tuning method and apparatus, assembly method, medium, and program product. Background Technology

[0002] With the continuous advancement of mobile communication technology, electronic devices such as mobile phones need to support an increasing number of communication standards and antennas. To ensure that the antenna can effectively transmit and receive wireless signals, it is usually necessary to reliably ground the antenna on the mobile phone to suppress radiated or conducted electromagnetic interference (EMI) from outside or inside the phone.

[0003] However, improper grounding design for mobile phone antennas or oxidation of the grounding metal surface can cause nonlinear effects to be generated on the grounding metal components by the wireless signals emitted by high-power antennas, thus producing harmonics. If these harmonics fall within the antenna's receiving frequency band, they will reduce the antenna's performance in receiving wireless signals, causing the antenna to fail the Radiated Spurious Emission (RSE) test in Electromagnetic Compatibility (EMC) certification.

When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0072] The technical solutions provided by the various embodiments of this disclosure are described in detail below with reference to the accompanying drawings.

[0073] Figure 1 This is a schematic diagram of the structure of an electronic device according to an exemplary embodiment. Figure 1 ,like Figure 1 As shown, the electronic device 1 may include:

[0074] The antenna radiator 11 has a first conductive surface 111;

[0075] The coupling component 12 is disposed at a distance from the antenna radiator 11 and grounded, and has a second conductive surface 121; the second conductive surface 121 is disposed opposite to the first conductive surface 111.

[0076] An insulating component 13 is located between the antenna radiator 11 and the coupling component 12, and connects the first conductive surface 111 and the second conductive surface 121.

[0077] The antenna radiator 11 and the coupling component 12 are coupled together so that the antenna radiator 11 is grounded.

[0078] In this embodiment of the disclosure, the electronic device may include: mobile phone, tablet computer, smartwatch, digital camera, head-mounted display (HMD) device, etc., and there is no limitation thereto.

[0079] In some embodiments, the electronic device further includes a mid-frame; antenna radiators are distributed on the mid-frame; or, the mid-frame includes a conductive border that is reused as an antenna radiator. Thus, the mid-frame of the electronic device can be configured as an antenna radiator in different ways, increasing the diversity of antenna radiator placement within the electronic device.

[0080] In some embodiments, the coupling component includes a display module or a back cover. Thus, the antenna radiator can be coupled to different components of the electronic device, all of which can ground the antenna radiator, thereby improving antenna performance while increasing the layout diversity of the internal space of the electronic device.

[0081] In other words, the antenna radiator can be the mid-frame of the electronic device, and the coupling component can be the display module of the electronic device; or, the antenna radiator can be the mid-frame of the electronic device, and the coupling component can be the back shell of the electronic device.

[0082] The mid-frame can be the frame that carries various internal components in an electronic device. The display module can include the display screen of the electronic device and the touch panel located on the light-emitting side of the display screen; the second conductive surface can be a conductive surface located on the non-light-emitting side of the display screen, such as a metal surface.

[0083] Here, the mid-frame can be located between the display module and the back cover of the electronic device, and both the display module and the back cover can be mounted on the mid-frame.

[0084] In this embodiment of the disclosure, the first conductive surface may be the surface of the antenna radiator facing the coupling component; the first conductive surface may be a chemically stable and highly conductive material, such as a metal plating composed of gold, nickel, copper, etc.

[0085] Similarly, the second conductive surface can be the surface of the coupling component facing the antenna radiator; the second conductive surface can also be a chemically stable and highly conductive material, such as a metal plating made of gold, nickel, copper, etc.

[0086] It should be noted that the first conductive surface and the second conductive surface can be parallel to each other. The spacing between the antenna radiator and the coupling component in the electronic device, that is, the spacing between the first conductive surface and the second conductive surface, can be from 0.1 mm to 0.25 mm.

[0087] Understandably, the area of ​​the first conductive surface can be the same as the area of ​​the second conductive surface to enable better coupling between the antenna radiator and the coupling component. For example, the area of ​​both the first and second conductive surfaces can be 9 mm. 2 -100mm 2 .

[0088] It should be noted that the materials of the first conductive surface and the second conductive surface can be the same or different, and this disclosure does not impose any restrictions.

[0089] In this embodiment of the disclosure, the antenna radiator can be used in an electronic device to transmit and receive wireless signals.

[0090] It should be noted that the specific types of wireless signals transmitted and received by the antenna radiator can be set according to the actual application scenario, and this disclosure does not impose any limitations. For example, the antenna radiator can transmit and receive NFC signals, cellular mobile communication signals, Wi-Fi communication signals, Bluetooth communication signals, or Global Positioning System (GPS) signals, etc.

[0091] Furthermore, the specific shape of the antenna radiator can be set according to the actual application scenario, and this disclosure does not impose any limitations. For example, the antenna radiator can be in the shape of a line or an L, etc.

[0092] In some embodiments, such as Figure 2 As shown, the antenna radiator 11 and the coupling component 12 can be coupled to form a coupling capacitor C, which is used to realize the non-contact electrical connection between the antenna radiator 11 and the coupling component 12.

[0093] In this way, by setting an insulating component between the antenna radiator and the coupling component, a coupling capacitor can be formed between the antenna radiator and the coupling component, thereby enabling the antenna radiator to be grounded and conducting through the coupling capacitor, thus improving the performance of the antenna radiator in transmitting and receiving wireless signals.

[0094] Here, non-contact electrical connection between the antenna radiator and the coupling component can be achieved through the coupling feeding effect of the coupling capacitor formed between the antenna radiator and the coupling component.

[0095] In this embodiment, the capacitor used for signal transmission via capacitive coupling is a parallel capacitor plate. The formula for calculating the capacitance C of the parallel capacitor plate is:

[0096] C=ε*ε0*S / d (1)

[0097] Where C is the capacitance of the parallel capacitor plates; ε is the relative permittivity of the insulating component; ε0 is the vacuum permittivity; S is the area of ​​the capacitor plates, which is directly proportional to the area of ​​the first or second conductive surface; d is the distance between the two capacitor plates, which is also directly proportional to the distance between the first and second conductive surfaces.

[0098] In some embodiments, the insulating element is a compressible elastic material, and the dielectric constant of the insulating element ranges from 10 to 100 farads per meter (F / m). Thus, with a fixed spacing between the antenna radiator and the coupling component, increasing the dielectric constant of the insulating element increases the coupling capacitance between the antenna radiator and the coupling component, thereby better grounding the antenna radiator through the coupling capacitance and improving the performance of the antenna radiator in transmitting and receiving wireless signals.

[0099] Here, the insulating element can be a compressible elastic material with a high dielectric constant; for example, the insulating element can be barium titanate (BaTiO3), polymer-based composite material, or porous material.

[0100] It is understandable that the insulating component can be integrally formed; that is, the contact area between the insulating component and the first conductive surface is equal to the area of ​​the first conductive surface. Alternatively, there can be multiple insulating components, which are spaced apart between the first and second conductive surfaces; in this case, the contact area between the insulating component and the first conductive surface is smaller than the area of ​​the first conductive surface.

[0101] In this embodiment of the present disclosure, there are multiple first conductive surfaces on the antenna radiator and multiple second conductive surfaces on the coupling component; at this time, there can also be multiple insulating components, which are spaced apart between the antenna radiator and the coupling component, and each insulating component is connected to the first conductive surface and the second conductive surface.

[0102] It should be noted that the insulating component can be bonded between the first conductive surface and the second conductive surface by insulating adhesive; or, the insulating component can also be disposed between the first conductive surface and the second conductive surface by snap-fitting. This disclosure does not impose any limitations on the embodiments.

[0103] In related technologies, to ensure that the antenna can effectively transmit and receive wireless signals, such as Figure 3 As shown, the first electrical contact surface 31 of the mobile phone screen typically needs to be reliably grounded to the second electrical contact surface 33 of the mobile phone's metal frame through a spring, foam encapsulation 32 (e.g., conductive cloth wrapped around foam), or omnidirectional foam. Such a grounding design can effectively suppress external or internal radiated or conducted EMI.

[0104] However, improper grounding design for mobile phone antennas or oxidation of the grounding metal surface can induce nonlinear effects on the grounding metal components due to the wireless signals transmitted by high-power antennas, thereby generating harmonics. The generation of these nonlinear effects is related to multiple factors, including the type of metal plating on the grounding component, the magnitude of the contact force, and the degree of compression. These factors collectively affect the electrical characteristics of the grounding point, leading to the occurrence of nonlinear effects and thus impacting the electromagnetic compatibility performance of the mobile phone antenna.

[0105] For example, passive intermodulation interference in mobile phones mainly originates from two types of passive nonlinearity: contact nonlinearity and material nonlinearity. Contact nonlinearity refers to any metal contact exhibiting nonlinear current-voltage characteristics. Its mechanism includes: a surface oxide film forming a "metal-insulator-metal" structure on the metal contact surface, exhibiting semiconductor-like pn junction characteristics due to the tunneling effect; and when electrons at the metal-metal contact surface have sufficient energy to pass through the potential barrier formed by the dielectric, current conduction occurs between the metals, known as the electrothermal effect. Material nonlinearity refers to ferromagnetic materials, carbon fibers, and iron-nickel-cobalt alloys, which possess inherent nonlinear conductor characteristics. Besides the two passive nonlinear mechanisms mentioned above, other nonlinear effects exist, such as stains or wear on the metal surface.

[0106] The impact of passive intermodulation in mobile applications, such as Figure 4a As shown, when two transmission signals F1 and F2 are transmitted simultaneously, intermodulation products are generated due to the passive nonlinearity of the mobile phone grounding, falling into the wireless reception band and degrading the reception sensitivity. Specifically, the third-order intermodulation products (IM3) are: 2F2-F1, 2F1-F2; and the fifth-order intermodulation products (IM5) are: 3F2-2F1, 3F1-2F2. Figure 4b As shown, when a single signal F1 is transmitted, harmonic products (2F1, 3F1, etc.) generated by the passive nonlinearity of the mobile phone grounding fall into the wireless receiving band, thus degrading the receiving sensitivity; or, its harmonic energy exceeds the electromagnetic compatibility (EMC) certification test item RSE failure, which causes the antenna to fail the RSE item in the EMC certification test, reducing the antenna's performance in receiving wireless signals.

[0107] An embodiment of this disclosure provides an electronic device comprising: an antenna radiator having a first conductive surface; a coupling component being disposed at a distance from the antenna radiator and grounded, and having a second conductive surface; the second conductive surface being disposed opposite to the first conductive surface; and an insulating component being located between the antenna radiator and the coupling component, and connecting the first conductive surface and the second conductive surface; wherein the antenna radiator and the coupling component are coupled to ground the antenna radiator.

[0108] In other words, unlike related technologies that use grounding metal to ground the antenna in a contact manner, the embodiments of this disclosure can provide an insulating component between the antenna radiator and the coupling component, and connect the first conductive surface of the antenna radiator and the second conductive surface of the coupling component in a non-contact manner, so that the antenna radiator and the coupling component can be coupled to ground the antenna radiator. This can effectively reduce the impact of oxidation of the metal contact surface on the antenna performance and improve the performance of the antenna radiator in transmitting and receiving wireless signals.

[0109] In some embodiments, such as Figure 5 As shown, there are multiple insulating components 13;

[0110] Multiple insulating elements 13 are spaced apart between the antenna radiator 11 and the coupling component 12, and each insulating element is connected to the first conductive surface 111 and the second conductive surface 121.

[0111] In this way, by setting multiple insulating elements at intervals between the antenna radiator and the coupling component, coupling capacitors can be formed at multiple locations between the antenna radiator and the coupling component, thereby better grounding the antenna radiator through the coupling capacitors and improving the performance of the antenna radiator in transmitting and receiving wireless signals.

[0112] In this embodiment of the disclosure, when the antenna radiator has a first conductive surface and the coupling component has a second conductive surface, each of the plurality of insulating components can be connected to the first conductive surface and the second conductive surface.

[0113] When the antenna radiator has multiple first conductive surfaces and the coupling component has multiple second conductive surfaces, each insulating component can be connected to a corresponding first conductive surface and a second conductive surface, that is, the first conductive surface and the second conductive surface connected to different insulating components are different.

[0114] It should be noted that the specific number of insulating components can be set according to the actual application scenario, as long as the number of insulating components is less than or equal to the number of the first conductive surface. This embodiment does not impose any restrictions.

[0115] In addition, the spacing between two adjacent insulating components can be the same or different, and can be set according to the structure of the electronic device in the actual application scenario. This disclosure does not impose any restrictions.

[0116] In some embodiments, such as Figure 6 As shown, the plurality of insulating elements 13 include:

[0117] The first insulating element 131 is connected to the first conductive surface 111;

[0118] The second insulating member 132 is stacked on top of the first insulating member 131 and connected to the second conductive surface 121;

[0119] The dielectric constant of the first insulating element 131 is different from that of the second insulating element 132.

[0120] Thus, by stacking a first insulating element and a second insulating element between the first conductive surface and the second conductive surface, and by having different dielectric constants for the first insulating element and the second insulating element, the coupling capacitance value formed between the antenna radiator and the coupling component can be increased to improve the performance of the antenna radiator in transmitting and receiving wireless signals.

[0121] In this embodiment of the disclosure, the first insulating element and the second insulating element can be insulating materials with different dielectric constants; for example, the first insulating element can be barium titanate, and the second insulating element can be a porous material, etc.

[0122] It is understandable that when calculating the coupling capacitance between the antenna radiator and the coupling component, an equivalent dielectric constant can be calculated first using the dielectric constants of the first and second insulating components. Then, based on this equivalent dielectric constant and the parallel capacitor plate formula, the equivalent capacitance value, i.e., the coupling capacitance between the antenna radiator and the coupling component, can be calculated.

[0123] It should be noted that the contact area between the first insulating member and the first conductive surface can be less than or equal to the area of ​​the first conductive surface, and the contact area between the second insulating member and the second conductive surface can also be less than or equal to the area of ​​the second conductive surface. This disclosure does not impose any limitations on the embodiments.

[0124] To ensure the stability of the internal structure of the electronic device, the first conductive surface, the first insulating component, the second insulating component, and the second conductive surface can be aligned; that is, the contact area of ​​the first insulating component and the second insulating component can be equal to the area of ​​the first conductive surface or equal to the area of ​​the second conductive surface.

[0125] Here, the first and second insulating components can also be bonded together with insulating adhesive to better ensure the stability of the internal structure of the electronic device.

[0126] It is understandable that when the antenna radiator has multiple first conductive surfaces and the coupling component has multiple second conductive surfaces, a first conductive surface and a second conductive surface form a group, and a first insulating component and a second insulating component can be stacked between the corresponding first conductive surface and second conductive surface in each group.

[0127] It should be noted that the specific number of insulating elements stacked between the first conductive surface and the second conductive surface can be set according to the actual application, as long as the spacing between the first conductive surface and the second conductive surface is met. This embodiment does not impose any limitations. For example, one, two, or three insulating elements may be stacked between the first conductive surface and the second conductive surface.

[0128] In some embodiments, such as Figure 7 As shown, electronic device 1 also includes:

[0129] The first conductive element 141 is located between the first conductive surface 111 and the insulating element 13; and / or,

[0130] The second conductive element 142 is located between the insulating element 13 and the second conductive surface 121.

[0131] Thus, by placing the first conductive element between the first conductive surface and the insulating element, and / or placing the second conductive element between the insulating element and the second conductive surface, the conductivity of the first conductive surface and / or the second conductive surface can be increased, thereby further improving the grounding effect of the antenna radiator.

[0132] In this embodiment, the first conductive element can be used to increase the conductivity of the first conductive surface, and the second conductive element can be used to increase the conductivity of the second conductive surface. Both the first and second conductive elements can be metal plating.

[0133] Here, in the case where an insulating film is formed on the first conductive surface and the second conductive surface after long-term oxidation, the embodiments of this disclosure can provide another first conductive element between the first conductive surface and the insulating element, that is, provide a metal plating layer on the first conductive surface to increase the conductivity of the first conductive surface; similarly, a second conductive element can be provided between the insulating element and the second conductive surface, that is, provide a metal plating layer on the second conductive surface to increase the conductivity of the second conductive surface.

[0134] It should be noted that the first conductive element can cover the first conductive surface, and the second conductive element can cover the second conductive surface; that is, the area of ​​the first conductive element can be the same as the area of ​​the first conductive surface, and the area of ​​the second conductive element can be the same as the area of ​​the second conductive surface.

[0135] Figure 8This is a schematic flowchart illustrating an assembly method for an electronic device according to an exemplary embodiment, such as... Figure 8 As shown in the embodiments of this disclosure, an assembly method for an electronic device may include at least the following steps:

[0136] Step 810: Detect the distance between the first conductive surface of the antenna radiator and the second conductive surface of the coupling component in the electronic device;

[0137] Step 820: Determine the dielectric constant based on the spacing;

[0138] Step 830: Assemble the insulating component with dielectric constant between the first conductive surface and the second conductive surface.

[0139] In this embodiment of the disclosure, the assembly method of the electronic device can be applied to an assembly device; the assembly device may be equipped with a robotic arm capable of gripping an insulating component having a determined dielectric constant, so as to assemble the insulating component between the first conductive surface of the antenna radiator and the second conductive surface of the coupling component in the electronic device.

[0140] In step 810, the assembly equipment can detect the distance between the first conductive surface of the antenna radiator and the second conductive surface of the coupling component in the electronic device.

[0141] The distance between the first conductive surface and the second conductive surface in the electronic device can be from 0.1 mm to 0.25 mm; that is, the distance detected by the assembly equipment can be any distance value within the distance range of 0.1 mm to 0.25 mm.

[0142] In steps 820 and 830, the correlation between each spacing and the dielectric constant of the set insulation can be determined by training a simulation model, and this correlation can be pre-stored in the assembly equipment.

[0143] Here, the assembly equipment can determine the dielectric constant of the insulating component to be assembled based on the detected spacing and the pre-stored correlation, and assemble the insulating component with the dielectric constant between the first conductive surface and the second conductive surface.

[0144] It should be noted that the distance between the first and second conductive surfaces is directly proportional to the dielectric constant of the insulating component; that is, the larger the distance between the first and second conductive surfaces, the larger the dielectric constant of the insulating component assembled in the electronic device. For example, if the distance between the first and second conductive surfaces is 0.1 mm, an insulating component with a dielectric constant of 40 F / m can be assembled in the electronic device; or, if the distance between the first and second conductive surfaces is 0.25 mm, an insulating component with a dielectric constant of 80 F / m can be assembled in the electronic device.

[0145] In this embodiment of the present disclosure, the dielectric constant of the insulating component to be assembled in the electronic device can be determined by the distance between the first conductive surface of the antenna radiator and the second conductive surface of the coupling component detected in the electronic device. The insulating component with the dielectric constant is then assembled between the first conductive surface and the second conductive surface, so that the antenna radiator and the coupling component can achieve non-contact electrical connection through the insulating component. This effectively reduces the impact of metal contact surface oxidation on antenna performance and improves the performance of the antenna radiator in transmitting and receiving wireless signals.

[0146] For example, in one embodiment of this disclosure, the distance between the first conductive surface of the antenna radiator and the second conductive surface of the coupling component is set to 0.1 mm, and the insulating component is made of a material with a dielectric constant of 40. The operating frequency band of the antenna radiator in the simulation model is 900 MHz, such as the N41 and N78 bands. The simulation comparison results are as follows... Figure 9a and Figure 9b As shown. Figure 9a In the network diagram, the horizontal axis represents the frequency band of the antenna radiator for transmitting and receiving signals (in GHz), and the vertical axis represents the radiation efficiency of the antenna radiator (in dB). Figure 9b In the network diagram, the horizontal axis represents the frequency band of the antenna radiator's transmitted and received signals (in GHz), and the vertical axis represents the S-parameters. The S-parameters measure the matching effect of the antenna radiator and the antenna's radiation performance (in dB). Specifically, the S11 parameter characterizes the input return loss; the lower the S11, the less loss occurs on the antenna due to reflection, resulting in more signal radiated into space and stronger antenna radiation performance. Figure 9a and Figure 9b As shown, the solid line represents the radiation efficiency corresponding to contact-type electrical connections in traditional electronic devices, while the dashed line represents the radiation efficiency corresponding to a distance of 0.1 mm between the first and second conductive surfaces and a dielectric constant of 40 for the insulating component. It is evident that the antenna radiation efficiencies of the two schemes are consistent; that is, by placing an insulating component between the antenna radiator and the coupling component, the impact of oxidation of the metal contact surface on antenna performance can be reduced, while simultaneously achieving a performance close to that of contact-type electrical connections in transmitting and receiving wireless signals.

[0147] In another embodiment of this disclosure, the distance between the first conductive surface of the antenna radiator and the second conductive surface of the coupling member is set to 0.25 mm, and the insulating member is made of a material with a dielectric constant of 40. Figure 9c In the network diagram, the horizontal axis represents the frequency band of the antenna radiator's signal transmission and reception (in GHz), and the vertical axis represents the radiation efficiency of the antenna radiator (in dB). Figure 9dIn the network diagram, the horizontal axis represents the frequency band of the antenna radiator's transmitted and received signals (in GHz), and the vertical axis represents the S-parameters. The S-parameters are used to measure the matching effect of the antenna radiator and the antenna's radiation effect (in dB). Figure 9c and Figure 9d As shown, the solid line and the thick dashed line are respectively... Figure 9a , Figure 9b The curves are consistent with those in the original text, while the newly added thin dashed line represents the radiation efficiency when the distance between the first and second conductive surfaces is 0.25 mm and the dielectric constant of the insulating component is 40. It can be seen that when the distance between the first and second conductive surfaces increases to 0.25 mm, the radiation efficiency of the antenna radiator deteriorates at the operating frequency of approximately 3.5 GHz, while the S11 parameter of the antenna radiator does not change significantly.

[0148] In another embodiment of this disclosure, the distance between the first conductive surface of the antenna radiator and the second conductive surface of the coupling component is set to 0.25 mm, and the insulating component is made of a material with a dielectric constant of 80. Figure 9e In the network diagram, the horizontal axis represents the frequency band of the antenna radiator's signal transmission and reception (in GHz), and the vertical axis represents the antenna radiator's radiation efficiency (in dB). For example... Figure 9e As shown, the thick solid line and the thick dashed line are respectively... Figure 9a , Figure 9b The curves in the middle are consistent, and the thin dashed lines are consistent with... Figure 9c , Figure 9d The thin dashed lines in the diagram are consistent with the previous ones, while the newly added thin solid lines represent the radiation efficiency when the distance between the first and second conductive surfaces is 0.25 mm and the dielectric constant of the insulating component is 80. It can be seen that by increasing the distance between the first and second conductive surfaces to 0.25 mm, increasing the dielectric constant of the insulating component can improve the radiation efficiency of the antenna radiator at the operating frequency of approximately 3.5 GHz, thus improving the performance of the previously degraded 3.5 GHz band to near that of a contact-type electrical connection antenna.

[0149] Figure 10 This is a circuit diagram of an antenna radiator in an electronic device according to an exemplary embodiment, such as... Figure 10 As shown, electronic device 1 also includes:

[0150] The tuning circuit 20 is connected to the antenna radiator 11 and is configured to tune the impedance on the connection line where the antenna radiator 11 is located and / or the radiation length of the antenna radiator 11.

[0151] In this way, by setting up a tuning circuit connected to the antenna radiator, the impedance on the connecting line where the antenna radiator is located and / or the radiation length of the antenna radiator can be tuned, thereby achieving impedance matching between the antenna radiator and the RF terminal, or adjusting the effective length of the antenna radiator to improve the radiation efficiency of the antenna radiator.

[0152] Here, the tuning circuit can be a circuit that optimizes antenna performance. It should be noted that the tuning circuit may include at least one of the following: impedance tuning circuit and aperture tuning circuit, and this disclosure does not limit this.

[0153] In one embodiment of this disclosure, such as Figure 10 As shown, the antenna radiator 11 has a first upper frame point 21 and a second upper frame point 24 spaced apart from the first upper frame point 21; the tuning circuit 20 includes:

[0154] Impedance tuning circuit 22, connected between the first upper frame point 21 and the radio frequency terminal 23 of the electronic device, is configured to tune the impedance on the connection line between the radio frequency terminal 23 and the first upper frame point 21; and / or,

[0155] The aperture tuning circuit 25, with one end connected to the second upper frame point 24 and the other end grounded, is configured to tune the radiation length of the antenna radiator 11.

[0156] Thus, by setting an impedance tuning circuit between the first upper frame point and the RF terminal of the electronic device, the impedance on the connection line between the RF terminal and the first upper frame point can be tuned, thereby achieving impedance matching between the antenna radiator and the RF terminal to reduce losses caused by impedance mismatch; and / or, by setting an aperture tuning circuit between the second upper frame point and the ground line, the radiation length of the antenna radiator can be tuned, thereby adjusting the effective length of the antenna radiator and switching the resonant point to the required operating frequency band to improve the radiation efficiency of the antenna radiator.

[0157] In this embodiment of the disclosure, the impedance tuning circuit can be a circuit that tunes the impedance on the connection line between the radio frequency terminal and the first upper frame point. The first upper frame point can be the connection point between the impedance tuning circuit and the antenna radiator.

[0158] The aforementioned aperture tuning circuit can be a circuit for tuning the radiation length of the antenna radiator. The first upper frame point can be the connection point between the aperture tuning circuit and the antenna radiator.

[0159] Understandably, the radio frequency (RF) terminal of the electronic device is connected to the RF circuit on the motherboard. A first electrical signal output from this RF terminal can be transmitted to the antenna radiator via the connection line between the RF terminal and the first upper frame point, causing the antenna radiator to radiate a wireless signal under the excitation of the first electrical signal. Alternatively, a second electrical signal obtained by the antenna radiator converting the wireless signal can be transmitted to the aforementioned RF circuit via the connection line between the RF terminal and the first upper frame point. In this case, during the transmission of the first or second electrical signal, the impedance tuning circuit can tune the impedance on the connection line between the RF terminal and the first upper frame point to reduce the loss caused by the impedance mismatch between the antenna radiator and the RF terminal, thereby increasing the transmission power of the first or second electrical signal and improving the radiation efficiency of the antenna radiator.

[0160] It should be noted that the impedance tuning circuit may include electronic components such as inductors, capacitors, and switches. The specific types and quantities of components included in the impedance tuning circuit can be set according to the actual application scenario, and this disclosure does not impose any limitations.

[0161] In this embodiment of the disclosure, the radiation length of the antenna radiator can be different depending on the impedance element connected in the aperture tuning circuit, thereby enabling the antenna radiator to radiate wireless signals of different frequency bands to achieve full-band wireless signal coverage.

[0162] It should be noted that the aperture tuning circuit may include electronic components such as capacitors and switches. The specific types and quantities of components included in the aperture tuning circuit can be set according to the actual application scenario, and this disclosure does not impose any limitations.

[0163] Figure 11 This is a flowchart illustrating a tuning method according to an exemplary embodiment. Figure 1 ,like Figure 11 As shown in the embodiments of this disclosure, a tuning method applied to an electronic device may include the following steps:

[0164] Step 1110: Send the initial parameter values ​​corresponding to the tuning circuit connected to the antenna radiator in the electronic device to the calibration equipment;

[0165] Step 1120: Receive the target parameter value returned by the calibration device; wherein the target parameter value is obtained by the calibration device based on the initial parameter value;

[0166] Step 1130: Adjust the parameter values ​​corresponding to the tuning circuit to the target parameter values ​​so that the transmit and receive power of the antenna radiator meets the preset range.

[0167] In step 1110, the aforementioned calibration device can be responsible for calibrating the parameter values ​​corresponding to the tuning circuit in the electronic device.

[0168] The initial parameter values ​​mentioned above can be the parameter values ​​corresponding to the tuning circuit set in the electronic device; for example, the initial parameter values ​​can be the capacitance value of the capacitor element in the tuning circuit, or the inductance value of the inductor element, etc.

[0169] In this embodiment of the disclosure, when the developer detects that the distance between the antenna radiator and the coupling component of the electronic device is greater than a preset distance threshold, the electronic device is controlled to send the initial parameter value corresponding to the tuning circuit to the calibration device; or, when the detection instrument detects that the distance between the antenna radiator and the coupling component of the electronic device is greater than a preset distance threshold, the electronic device is controlled to send the initial parameter value corresponding to the tuning circuit to the calibration device.

[0170] Understandably, in practical applications, the antenna radiator and coupling components in electronic devices are already set up. When structural tolerances occur at the locations of the antenna radiator and coupling components, i.e., when the distance between the antenna radiator and coupling components increases, the performance of the antenna radiator will degrade. In this case, the electronic device can be connected to a calibration device to calibrate the parameter values ​​of the tuning circuit in the electronic device, thereby improving the transmit and receive power of the antenna radiator in subsequent processes and optimizing the performance of the antenna radiator.

[0171] In step 1120, the target parameter value can be a parameter value determined by the calibration device based on the initial parameter value corresponding to the tuning circuit.

[0172] Here, after receiving the initial parameter values ​​from the electronic device, the calibration equipment can determine the current transmit and receive power of the antenna radiator by conducting a simulation experiment on the antenna radiator's wireless signal transmission and reception. Then, by determining whether the current transmit and receive power of the antenna radiator meets a preset range, the equipment adaptively adjusts the corresponding parameter values ​​of the tuning circuit until the transmit and receive power of the antenna radiator is adjusted to meet the preset range, thus determining the parameter value corresponding to the tuning circuit at this point, i.e., the target parameter value. After determining the target parameter value through the simulation experiment, the calibration equipment returns this target parameter value to the electronic device.

[0173] In step 1130, the preset range can be the transmit and receive power value of the wireless signal when the antenna radiator has excellent transmit and receive performance. This embodiment of the present disclosure can be set according to the actual application situation, and there is no limitation thereto.

[0174] In one embodiment of this disclosure, the tuning circuit includes an impedance tuning circuit and / or an aperture tuning circuit; the target parameter value includes a first parameter value corresponding to the impedance tuning circuit and / or a second parameter value corresponding to the aperture tuning circuit; step 1130, adjusting the parameter value corresponding to the tuning circuit to the target parameter value, includes:

[0175] Adjust the parameter value corresponding to the impedance tuning circuit to the first parameter value; and / or,

[0176] Adjust the parameter value corresponding to the aperture tuning circuit to the second parameter value.

[0177] Thus, by adjusting the parameter values ​​of the impedance tuning circuit and / or the aperture tuning circuit, the transmit and receive power of the antenna radiator can be made to meet the preset range, thereby improving the performance of the antenna radiator in transmitting and receiving wireless signals.

[0178] Here, the first parameter value can be the parameter value returned by the calibration equipment for adjusting the parameter value corresponding to the impedance tuning circuit; the second parameter value can be the parameter value returned by the calibration equipment for adjusting the parameter value corresponding to the aperture tuning circuit.

[0179] For example, an electronic device can optimize the antenna radiation efficiency of its antenna radiator at an operating frequency of 3.5 GHz by adjusting the parameter values ​​corresponding to the impedance tuning circuit, such as adjusting the capacitance value of the series tuning capacitor in the impedance tuning circuit from 1 picofarad (pF) to 0.63 pF. Figure 12 As shown, the dashed line represents the antenna radiation efficiency of the antenna radiator before the parameters of the impedance tuning circuit are adjusted, and the solid line represents the antenna radiation efficiency of the antenna radiator after the parameters of the impedance tuning circuit are adjusted. See also... Figure 12 By adjusting the capacitance value of a series tuning capacitor in the impedance tuning circuit, the antenna radiation efficiency of the antenna radiator at the 3.5 GHz operating frequency can be improved, while the radiation efficiency at other operating frequencies remains unchanged.

[0180] The tuning method provided in this disclosure can calibrate the initial parameter values ​​corresponding to the tuning circuit in an electronic device using a calibration device, so as to adjust the parameter values ​​corresponding to the impedance tuning circuit and / or the aperture tuning circuit, so that the transmit and receive power of the antenna radiator meets the preset range. Thus, when structural tolerances occur at the location of the antenna radiator and the coupling component of the electronic device, the performance of the antenna radiator in transmitting and receiving wireless signals can be improved by adjusting the parameter values ​​corresponding to the tuning circuit.

[0181] Figure 13 This is a flowchart illustrating a tuning method according to an exemplary embodiment. Figure 2 .like Figure 13 As shown, the tuning methods provided in this disclosure are merely examples and not limitations, intended to help those skilled in the art better understand the technical solutions of this disclosure. See also Figure 13 The tuning method provided in this disclosure, when applied to a calibration device, may include the following steps:

[0182] Step 1301: Based on the initial parameter values ​​corresponding to the tuning circuit connected to the antenna radiator transmitted by the electronic device, detect the transmit and receive power of the antenna radiator.

[0183] Step 1302: Determine whether the current transmit and receive power of the antenna radiator does not meet the preset range; if yes, proceed to step 1303; if no, proceed to step 1305.

[0184] Step 1303: Based on the initial parameter values, adjust the parameter values ​​corresponding to the tuning circuit to the preset sample values.

[0185] Here, when the parameter value corresponding to the tuning circuit is a preset sample value, the transmit and receive power of the antenna radiator is set to the sample transmit and receive power.

[0186] Step 1304: Determine whether the sample transmit and receive power of the antenna radiator meets the preset range; if yes, proceed to step 1305; if no, proceed to step 1303.

[0187] Step 1305: Use the parameter values ​​of the tuning circuit set when the antenna radiator meets the preset range as the target parameter values.

[0188] Here, after determining the target parameter value by conducting a simulation experiment on the transmission and reception of wireless signals by the antenna radiator, the calibration equipment returns the target parameter value to the electronic device, so that the electronic device can adjust the corresponding parameter value of the tuning circuit based on the received target parameter value, thereby ensuring that the transmission and reception power of the antenna radiator meets the preset range.

[0189] The tuning method provided in this disclosure can calibrate the initial parameter values ​​corresponding to the tuning circuit in an electronic device using a calibration device, so as to adjust the parameter values ​​corresponding to the impedance tuning circuit and / or the aperture tuning circuit, so that the transmit and receive power of the antenna radiator meets the preset range. Thus, when structural tolerances occur at the location of the antenna radiator and the coupling component of the electronic device, the performance of the antenna radiator in transmitting and receiving wireless signals can be improved by adjusting the parameter values ​​corresponding to the tuning circuit.

[0191] The transmitting module 1410 is configured to transmit the initial parameter values ​​corresponding to the tuning circuit connected to the antenna radiator in the electronic device to the calibration device.

[0192] The receiving module 1420 is configured to receive the target parameter value returned by the calibration device; wherein the target parameter value is obtained by the calibration device based on the initial parameter value;

[0193] The processing module 1430 is configured to adjust the parameter values ​​corresponding to the tuning circuit to the target parameter values ​​so that the transmit and receive power of the antenna radiator meets the preset range.

[0194] The tuning device provided in this embodiment can calibrate the initial parameter values ​​corresponding to the tuning circuit in the electronic device through a calibration device, so as to adjust the parameter values ​​corresponding to the impedance tuning circuit and / or the aperture tuning circuit, so that the transmit and receive power of the antenna radiator meets the preset range. Therefore, when there are structural tolerances at the location of the antenna radiator and the coupling component of the electronic device, the performance of the antenna radiator in transmitting and receiving wireless signals can be improved by adjusting the parameter values ​​corresponding to the tuning circuit.

[0195] for Figure 14 In one possible implementation of the technical solution shown, the target parameter value includes a first parameter value corresponding to the impedance tuning circuit and / or a second parameter value corresponding to the aperture tuning circuit; the processing module 1430 is specifically configured to: adjust the parameter value corresponding to the impedance tuning circuit to the first parameter value; and / or, adjust the parameter value corresponding to the aperture tuning circuit to the second parameter value.
