Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an antenna system. Background Art

[0002] As the hardware speeds of electronic devices such as laptops and mobile phones increase, their power consumption also increases. The electromagnetic interference signals generated by these high-power hardware also become stronger, causing more severe interference to the antennas of these electronic devices. Currently, the main method for reducing electromagnetic interference in electronic devices is to use management engine solutions. However, this noise reduction method requires the installation of a separate management engine unit in the electronic device, which is not only costly but also affects the production efficiency of the electronic device. Therefore, proposing a new solution to reduce electromagnetic interference in electronic devices has become a technical problem that needs to be solved urgently. Summary of the Invention

[0003] The present application provides an antenna system, aiming to solve the problem of high electromagnetic interference between antennas in the antenna system existing in the related art.

[0004] In a first aspect of the present application, an antenna system is provided, comprising:

[0005] The antenna substrate comprises a first plane, a second plane and a third plane, wherein the first plane is paved with a target metal material for reflecting electromagnetic waves of at least one of the first antenna and the second antenna;

[0006] A first antenna is configured on the second plane and / or the third plane of the antenna substrate and is used to transmit a signal in a first preset frequency band;

[0007] The second antenna is configured on the second plane and / or the third plane of the antenna substrate and is used to transmit a signal in a second preset frequency band. The first antenna is different from the second antenna.

[0008] In one embodiment, the first antenna and the second antenna are disposed on the same plane of the antenna substrate, and the distance between the first antenna and the second antenna is greater than the first predetermined coupling distance.

[0009] In one embodiment, the first antenna and the second antenna are disposed on different planes of the antenna substrate, and the distance between the first antenna and the second antenna is greater than the second predetermined coupling distance.

[0010] In one embodiment, the first plane and the second plane are adjacent and perpendicular to each other, the second plane and the third plane are adjacent and perpendicular to each other, and the first plane and the third plane are opposite and parallel to each other.

[0011] In one embodiment, the antenna substrate further includes a fourth plane, the fourth plane is grounded, the fourth plane is adjacent to and perpendicular to the first plane, the fourth plane is adjacent to and perpendicular to the third plane, and the fourth plane is opposite to and parallel to the second plane.

[0012] In one embodiment, the antenna system further includes a control module for controlling at least one of the first antenna and the second antenna to receive and / or transmit signals.

[0013] In one embodiment, the first antenna and / or the second antenna is arranged on the second plane and / or the third plane of the antenna substrate by a target fixture.

[0014] In one embodiment, the first antenna is disposed in a first groove of the antenna substrate. The first groove is a region recessed from the second plane or the third plane toward the inside of the antenna substrate. The size of the first groove matches that of the first antenna.

The first plane on which the target metal material is laid can serve as an isolation barrier, reflecting electromagnetic waves generated by each antenna in the antenna system when transmitting or receiving signals that would interfere with other antennas in the antenna system, thereby reducing the probability that other antennas will be interfered with by the electromagnetic waves of the antenna. In other words, the first plane on which the target metal material is laid can improve the isolation between the first and second antennas, reduce the electromagnetic interference between the first and second antennas, and thus improve the antenna's signal transmission and reception performance. In addition, by configuring the first antenna, the second antenna, and the target metal material on the antenna substrate structure, there is no need to add additional interference reduction structures, which can achieve the goal of reducing electromagnetic interference while also reducing noise reduction costs.

[0031] In order to make the purpose, features, and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0032] Since the current noise reduction method of reducing electromagnetic interference through management engine solutions is not only costly but also affects the production efficiency of electronic devices, in order to reduce electromagnetic interference while reducing noise reduction costs, this application proposes an antenna system.

[0033] The technical solutions of the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0034] Figure 1 FIG. 1 shows a schematic diagram of the structure of the antenna system provided in an embodiment of the present application. Figure 1 As shown, the antenna system includes an antenna substrate 101 , a first antenna 102 and a second antenna 103 .

[0035] The antenna substrate 101 includes a first plane, a second plane, and a third plane. The first plane is paved with a target metal material for reflecting electromagnetic waves of at least one of the first antenna and the second antenna.

[0036] The first antenna 102 is disposed on the second plane and / or the third plane of the antenna substrate and is used to transmit a first preset frequency band signal.

[0037] The second antenna 103 is disposed on the second plane and / or the third plane of the antenna substrate and is used to transmit a signal in a second preset frequency band. The first antenna is different from the second antenna.

[0038] In the present application, the antenna substrate may be a tetrahedral structure. The antenna substrate may further include a fourth plane. The fourth plane may be used for grounding.

[0039] In one optional implementation, the first and second planes of the antenna substrate are adjacent and perpendicular to each other, the second and third planes are adjacent and perpendicular to each other, and the first and third planes are opposite and parallel to each other. The fourth plane is adjacent and perpendicular to the first plane, the fourth plane is adjacent and perpendicular to the third plane, and the fourth plane is opposite and parallel to the second plane. By grounding the fourth plane, the antenna substrate can form a low-impedance circuit loop, allowing the antenna configured on the antenna substrate to connect to the ground through this path, ensuring normal operation of the antenna.

[0040] In this application, the first antenna and the second antenna can both be configured on the second plane; alternatively, the first antenna and the second antenna can both be configured on the third plane. The first antenna and the second antenna can be configured in different areas on the same plane of the antenna substrate. In this application, the first antenna and the second antenna can also be configured on the second plane and the third plane, respectively. For example, the first antenna can be configured on the second plane and the second antenna can be configured on the third plane, or the first antenna can be configured on the third plane and the second antenna can be configured on the second plane.

[0041] In an optional implementation, the first antenna and the second antenna may be arranged on the same plane of the antenna substrate, and the distance between the first antenna and the second antenna is greater than the first preset coupling distance.

[0042] In an optional implementation, the first antenna and the second antenna may also be arranged on different planes of the antenna substrate, and the distance between the first antenna and the second antenna is greater than the second preset coupling distance.

[0043] Because antennas on different planes may have different polarization directions, the propagation paths of signals transmitted or received by antennas on different planes also differ significantly. Therefore, coupling interference between antennas on different planes is lower, and the coupling distance between antennas deployed on different planes is shorter than the coupling distance between antennas deployed on the same plane. Therefore, the first preset coupling distance is typically greater than the second preset coupling distance.

[0044] In this application, the first preset coupling distance and the second preset coupling distance can be determined based on the actual operating frequency and operating environment of the antenna. In practice, the first preset coupling distance and the second preset coupling distance can be obtained by performing a coupling test on the antenna. Optionally, the first preset coupling distance can be set to 2 cm or 3 cm, and the second preset coupling distance can be set to 0.5 cm or 1 cm.

[0045] When the distance between antennas is no greater than the coupling distance, the coupling interference between the antennas is significant, affecting the quality of the signals transmitted and received by the antennas. In this application, by setting the distance between antennas deployed on the same plane to be greater than a first preset coupling distance, and setting the distance between antennas deployed on different planes to be greater than a second preset coupling distance, the coupling interference between the first and second antennas can be reduced, improving signal quality. Furthermore, the fact that both the first and second antennas are located on the antenna substrate simplifies the design of the antenna system.

[0046] In the present application, the antenna system may further include a control module for controlling at least one of the first antenna and the second antenna to receive and / or transmit signals. The control module may employ a radio frequency controller to manage the transmission and reception of signals by the first antenna and the second antenna. For example, the radio frequency controller may adjust the signal transmission power of the first antenna and / or the second antenna. The control module may employ a digital signal processor to manage the transmission and reception of signals by the first antenna and the second antenna. For example, the digital signal processor may modulate and demodulate the transmitted and received signals by the first antenna and / or the second antenna.

[0047] In an optional implementation, the antenna substrate may be a flexible polyhedral cell (FPC) tetrahedron, which may include a first plane, a second plane, a third plane, and a fourth plane.

[0048] Figure 2 A structural diagram of an FPC tetrahedron provided in an embodiment of the present application is shown, wherein: Figure 2 (a) in FIG. 1 shows an FPC tetrahedron 200. Figure 2 (b) in the figure shows the first plane of the FPC tetrahedron. Figure 2 (c) in the figure shows the second plane of the FPC tetrahedron. Figure 2 (d) in the figure shows the third plane of the FPC tetrahedron. Figure 2 (e) in the figure illustrates the fourth plane of the FPC tetrahedron. The first plane 210 and the fourth plane 240 are adjacent and perpendicular to each other, the first plane 210 and the second plane 220 are adjacent and perpendicular to each other, the second plane 220 and the third plane 230 are adjacent and perpendicular to each other, and the third plane 230 and the fourth plane 240 are adjacent and perpendicular to each other. The first plane 210 and the third plane 230 are opposite and parallel to each other, and the second plane 220 and the fourth plane 240 are opposite and parallel to each other.

[0049] like Figure 2 As shown, the first antenna 102 and the second antenna 103 can both be configured on the third plane 230 of the FPC tetrahedron. In the present application, the first antenna and the second antenna can also be configured on different planes of the FPC tetrahedron. For example, the first antenna can be configured on the second plane of the FPC tetrahedron and the second antenna can be configured on the third plane of the FPC tetrahedron. Alternatively, the first antenna can be configured on the third plane of the FPC tetrahedron and the second antenna can be configured on the second plane of the FPC tetrahedron.

[0050] In the present application, a target metal material can be laid on the first plane of the FPC tetrahedron. The first plane on which the target metal material is laid is used as an isolation barrier to reflect electromagnetic waves, so as to improve the isolation between the first antenna and the second antenna and reduce the electromagnetic interference between the first antenna and the second antenna. The target metal material can be a metal material that can reflect electromagnetic waves. Preferably, copper metal or nickel metal can be used as the target metal material. Since copper metal and nickel metal have a better effect of reflecting electromagnetic waves, and copper metal and nickel metal are lightweight metals, choosing copper metal or nickel metal as the target metal material can not only improve the reflection effect of the isolation barrier on the electromagnetic waves generated by each antenna in the antenna system that may interfere with other antennas, but also the lightweight metal material can prevent the antenna from being too heavy.

[0051] like Figure 2 As shown in (b) in the figure, a copper sheet 205 made of copper metal can be laid on the first plane 210. The length of the copper sheet 205 can be equal to the length of the first plane 210, the width of the copper sheet 205 can be equal to the width of the first plane 210, and the thickness of the copper sheet 205 can be set to 0.5 millimeters (mm) or 1 mm, etc. The copper sheet 205 laid on the first plane 210 can serve as an isolation barrier to reflect part of the electromagnetic waves transmitted and received by the first antenna that propagate to the second antenna, thereby reducing the impact of the signals transmitted and received by the first antenna on the second antenna, and the isolation barrier can also be used to reflect part of the electromagnetic waves transmitted and received by the second antenna that propagate to the first antenna, thereby reducing the impact of the signals transmitted and received by the second antenna on the second antenna. Therefore, the first plane 210 paved with copper metal material can reduce the problem of mutual interference between the radio frequency signal transmitted by the first antenna 102 and the radio frequency signal transmitted by the second antenna 103. In the present application, whether the first antenna and the second antenna are respectively configured in the second plane and the third plane, or the first antenna and the second antenna are jointly configured in the second plane or the third plane, the isolation retaining wall formed by the copper metal material can reflect part of the electromagnetic waves transmitted and received by the first antenna and propagated to the second antenna, and reflect part of the electromagnetic waves transmitted and received by the second antenna and propagated to the first antenna, thereby reducing the electromagnetic interference of the first antenna and the second antenna on each other when performing antenna transmission and reception activities.

[0052] like Figure 2 As shown in (d) and (e) of FIG, the first antenna 102 and the second antenna 103 arranged on the third plane 230 of the FPC tetrahedron can contact the fourth plane 240. Based on this, the fourth plane 240 can be grounded. By grounding the fourth plane 240, the first antenna 102 and the second antenna 103 can be grounded.

[0053] In the present application, the first antenna can receive or transmit a first preset frequency band signal. The frequency range of the first preset frequency band signal can be set according to user needs. For example, the first preset frequency band signal includes a 2.4 gigahertz (GHz) frequency band signal, a 5 GHz frequency band signal, and a 6 GHz frequency band signal. The first preset frequency band signal may also include a wireless signal in the 6 GHz frequency band.

[0054] In the present application, the second antenna can receive or transmit a second preset frequency band signal. The frequency range of the second preset frequency band signal can be set according to user needs. For example, the second preset frequency band signal includes a 2.4 GHz frequency band signal, a 5 GHz frequency band signal, and a 6 GHz frequency band signal. The second preset frequency band signal may also include a wireless signal in the 6 GHz frequency band.

[0055] In this application, the first antenna and the second antenna may transmit or receive signals in the same frequency band, or the first antenna and the second antenna may transmit or receive signals in different frequency bands. The first antenna and the second antenna may transmit or receive signals simultaneously, or the first antenna and the second antenna may transmit and / or receive signals at different times.

[0056] Since the wavelength of high-frequency band signals is shorter, high-frequency band signals are more likely to produce coherence and interference phenomena, resulting in stronger mutual interference when different high-frequency signals are close to each other. The antenna system provided in the present application increases the isolation between the signals transmitted and / or received by the first antenna and the second antenna by laying the target metal material on the first plane of the antenna base to form an isolation barrier. The improvement in signal isolation allows the first antenna and the second antenna to transmit and / or receive higher frequency band signals, such as 2.4GHz frequency band signals, 5GHz frequency band signals, and 6GHz frequency band signals. That is, the antenna system provided in the present application expands the frequency band range of the signals transmitted and / or received by each antenna in the antenna system, and the wider frequency band range can support higher data transmission rates and larger bandwidths. Therefore, the antenna system provided in the present application also improves the communication capability and network performance of the antenna.

[0057] In this application, the first and second antennas are positioned on the second and / or third planes of the antenna substrate via a target fixture. The target fixture can be mounted on the second and third planes of the antenna substrate to secure the first and second antennas to the second and / or third planes of the antenna substrate. To reduce electromagnetic interference with signals transmitted and / or received by the antennas, the target fixture can be made of an insulating material or a lightweight metal material. For example, the target fixture can be made of a plastic material.

[0058] In an optional implementation, the first antenna is configured in a first groove of the antenna substrate. The first groove is an area recessed from the second plane or the third plane into the interior of the antenna substrate, and the first groove is used to accommodate the first antenna. The size of the first groove matches the size of the first antenna. Figure 2 As shown in (d) in the figure, the first groove can be located in the area corresponding to the diagonal box on the left side of the third plane 230. In the present application, the position of the first groove can also be set according to application requirements. For example, the first groove can also be located in a specified area on the right side of the third plane. Alternatively, the position of the first groove can also be located in a specified area on the left or right side of the second plane. In practice, the size of the first groove matches the size of the first antenna, so that the first antenna can be smoothly embedded in the antenna base.

[0059] It should be noted that the size of the first groove matches the size of the first antenna, which can mean that the size of the first groove and the size of the first antenna meet at least one of the following three conditions. Condition 1: The geometric shape of the corresponding first groove on the second plane or the third plane is similar to the outline shape of the first antenna; Condition 2: The area of the geometric shape is larger than the area of the outline shape of the first antenna; Condition 3: The depth of the first groove is greater than or equal to the thickness of the first antenna. For example, if the first antenna is 30mm long, 20mm wide, and 5mm thick, the dimensions of the first groove on the second plane or the third plane for placing the first antenna can be: 31mm long, 21mm wide, and 5mm deep.

[0060] In an optional implementation, the second antenna is configured in a second groove of the antenna substrate. The second groove is an area recessed from the second plane or the third plane into the interior of the antenna substrate, and the second groove is used to accommodate the second antenna. The size of the second groove matches the size of the second antenna. Figure 2 As shown in (d) in the figure, the second groove can be located in the area corresponding to the diagonal frame on the right side of the third plane 230. In the present application, the position of the second groove can also be set according to application requirements. For example, the second groove can also be located in a specified area on the left side of the third plane. Alternatively, the position of the second groove can also be located in a specified area on the left or right side of the second plane. In practice, the size of the second groove matches the size of the second antenna, so that the second antenna can be smoothly embedded in the antenna base.

[0061] It should be noted that the second groove's dimensions matching those of the second antenna can mean that the dimensions of the second groove and the second antenna meet at least one of the following three conditions: Condition 1: The geometric shape of the corresponding second groove on the second or third plane is similar to the outline of the second antenna; Condition 2: The area of the geometric shape is greater than the area of the outline of the second antenna; Condition 3: The depth of the second groove is greater than or equal to the thickness of the second antenna. For example, if the second antenna is 40 mm long, 20 mm wide, and 4 mm thick, the dimensions of the second groove on the second or third plane for receiving the second antenna can be: 41 mm long, 21 mm wide, and 4 mm deep.

[0062] In the antenna system provided herein, a first antenna and / or a second antenna are arranged on the second and / or third planes of an antenna substrate, and a target metal material for reflecting electromagnetic waves is laid on the first plane of the antenna substrate. Because the target metal material can reflect electromagnetic waves from at least one of the first and second antennas, the first plane covered with the target metal material can serve as a barrier, reflecting electromagnetic waves generated by each antenna in the antenna system when transmitting or receiving signals that could interfere with other antennas, thereby reducing the probability of other antennas receiving interference from the electromagnetic waves of that antenna. In other words, the antenna system, with the target metal material laid on the first plane, can improve the isolation between the first and second antennas and reduce electromagnetic interference between them, thereby improving the antenna's signal transmission and reception performance. Furthermore, by arranging the first antenna, second antenna, and target metal material on the antenna substrate structure, there is no need for additional interference reduction structures, thereby reducing electromagnetic interference while also lowering noise reduction costs. Furthermore, the enhanced signal isolation of the antenna system can expand the frequency band of signals transmitted and received by the antenna, thereby improving the antenna system's communication capabilities, signal performance, and anti-interference capabilities.

[0063] Figure 3 A schematic diagram of the planar structure of the FPC tetrahedron provided in an embodiment of the present application is shown. Figure 3 The diagram shows the first plane, second plane, third plane and fourth plane of the FPC tetrahedron unfolded on the same surface. Figure 3 As shown, the four dotted boxes respectively show the first plane 210, the second plane 220, the third plane 230 and the fourth plane 240 of the FPC tetrahedron. Figure 3As shown, copper metal is laid on the first plane 210 of the FPC tetrahedron to form an isolation barrier. The first antenna 102 and the second antenna 103 can be configured on the third plane 230 of the FPC tetrahedron via the first signal soldering point 302-1 and the second signal soldering point 302-2. The fourth plane 240 of the FPC tetrahedron can be grounded via the first ground soldering point 303-1 and the second ground soldering point 303-2.

[0064] In the embodiment of the present application, the length of the FPC tetrahedron can be set to 90.51 mm, and the sum of the widths of the first plane, the second plane, the third plane, and the fourth plane of the FPC tetrahedron can be set to 18.28 mm. Figure 3 As shown, the sides of the FPC tetrahedron parallel to the OX direction are the length of the FPC tetrahedron, and the sides of the FPC tetrahedron parallel to the OY direction are the width of the FPC tetrahedron. Copper metal can be laid on the first plane 210 of the FPC tetrahedron to form an isolation barrier. For example, copper metal can be laid on the first plane of the FPC tetrahedron to form an isolation barrier with an area of 90.51 mm x 5.1 mm.

[0065] In the present application, the antenna system may further include a control module. The control module may be used to control at least one of the first antenna and the second antenna to receive and / or transmit signals. The control module may be a controller such as a microcontroller or a digital signal processor. The control module may be disposed on the antenna substrate, or may be disposed on a processor motherboard of the electronic device.

[0066] In the present application, the control module of the antenna system can determine the first signal modulation parameters required for transmitting and receiving the first preset frequency band signal according to the frequency band of the first preset frequency band signal received and transmitted by the first antenna, thereby controlling the first antenna to transmit and receive the first preset frequency band signal according to the first signal modulation parameters. The frequency band of the first preset frequency band signal can be 2.4GHz frequency band, 5GHz frequency band or 6GHz frequency band, etc. Figure 3 , the control module can control the first antenna 102 to transmit and / or receive first preset frequency band signals in the 2.4 GHz, 5 GHz and 6 GHz frequency bands.

[0067] The control module can also determine the second signal modulation parameters required for transmitting and receiving the second preset frequency band signal based on the frequency band of the second preset frequency band signal received and transmitted by the second antenna, thereby controlling the second antenna to transmit and receive the second preset frequency band signal based on the second signal modulation parameters. The frequency band of the second preset frequency band signal can be 2.4 GHz, 5 GHz, or 6 GHz. Figure 3The control module can control the second antenna 103 to transmit and / or receive signals in a second preset frequency band of 2.4 GHz, 5 GHz, and 6 GHz. In an optional embodiment, as the antenna system improves signal isolation, the control module can also control the first antenna and / or the second antenna to transmit radio frequency signals higher than the 6 GHz band.

[0068] In the present application, the control module of the antenna system can determine the frequency band of the signal received and transmitted by the antenna through an LC resonant circuit. The control module can adjust the signal modulation parameters of the LC resonant circuit. If the signal modulation parameters are adjusted to be consistent with the first signal modulation parameters, the signal transmission frequency or reception frequency can be made to reach the frequency band of the first preset frequency band signal, thereby controlling the first antenna to transmit or receive the first preset frequency band signal; if the signal modulation parameters are adjusted to be consistent with the second signal modulation parameters, the signal transmission frequency or reception frequency can be made to reach the frequency band of the second preset frequency band signal, thereby controlling the second antenna to transmit or receive the second preset frequency band signal.

[0069] In this application, the control module of the antenna system can determine the frequency band of the signal received and transmitted by the antenna through the equivalent circuit of the LC resonant circuit. The equivalent circuit of the LC resonant circuit includes an inductor L and a capacitor C. The relationship between the inductor L, the capacitor C and the resonant frequency satisfies the formula Where f0 is the resonant frequency, L is the inductance, and C is the capacitance. The resonant frequency is the transmission frequency or reception frequency at which the control module controls the antenna to transmit or receive signals. The signal modulation parameters may include the inductance and capacitance of the equivalent circuit of the LC resonant circuit.

[0070] Figure 4 A schematic diagram showing the equivalent circuit of an LC resonant circuit. Figure 4 In the equation, A represents a circuit node, B represents a circuit node, L represents an inductor, C represents a capacitor, and R represents a resistor. Since the LC resonant circuit can generate resonance at the resonant frequency, the present application can change the resonant frequency by adjusting the capacitance value or the inductance value of the LC resonant circuit, thereby changing the transmitting frequency and the receiving frequency of the antenna transmitting and receiving signals. For the first preset frequency band signal that needs to be transmitted or received by the first antenna, the frequency band of the first preset frequency band signal is known, and the frequency band of the first preset frequency band signal can be used as the resonant frequency f0 and substituted into the formula The product value of the inductance value and the capacitance value corresponding to the equivalent circuit of the LC resonant circuit is calculated, and each combination of the inductance value and the capacitance value whose product reaches the product value can be used as the first signal modulation parameter. Then the control module can adjust the inductance and capacitance in the LC resonant circuit of the antenna to the inductance value and capacitance value in the first signal modulation parameter respectively, so that the transmitting frequency or receiving frequency of the antenna system can reach the frequency band of the first preset frequency band signal, and the control module can realize the control of the first antenna to transmit or receive the first preset frequency band signal. For example, the frequency band of the first preset frequency band signal can be 5GHz, and 5GHz can be substituted into the formula as the resonant frequency The product value of the inductance and capacitance corresponding to the equivalent circuit of the LC resonant circuit can be calculated, and then the control module can adjust the inductance and capacitance in the LC resonant circuit of the antenna so that the product of the inductance and capacitance reaches the product value. In this way, the transmitting frequency or receiving frequency of the antenna system can reach 5 GHz, and the control module can control the first antenna to transmit or receive a 5 GHz signal.

[0071] For the second preset frequency band signal that needs to be transmitted or received by the second antenna, when the frequency band of the second preset frequency band signal is known, the frequency band of the second preset frequency band signal can be used as the resonant frequency f0 and substituted into the formula The product value of the inductance value and the capacitance value corresponding to the equivalent circuit of the LC resonant circuit is calculated, and each combination of the inductance value and the capacitance value whose product reaches the product value can be used as the second signal modulation parameter. Then the control module can adjust the inductance and capacitance in the LC resonant circuit of the antenna to the inductance value and capacitance value in the second signal modulation parameter respectively, so that the transmitting frequency or receiving frequency of the antenna system can reach the frequency band of the second preset frequency band signal, and the control module can realize the control of the second antenna to transmit or receive the second preset frequency band signal. For example, the frequency band of the second preset frequency band signal can be 2.4GHz, and 5GHz can be substituted into the formula as the resonant frequency The product value of the inductance and capacitance corresponding to the equivalent circuit of the LC resonant circuit can be calculated, and then the control module can adjust the inductance and capacitance in the LC resonant circuit of the antenna so that the product of the inductance and capacitance reaches the product value. In this way, the transmitting frequency or receiving frequency of the antenna system can reach 2.4 GHz, and the control module can control the second antenna to transmit or receive the 2.4 GHz signal.

[0072] In a possible implementation, the control module can also directly adjust the inductance and capacitance of the equivalent circuit of the LC resonant circuit, and substitute the inductance and capacitance into the formula: The resonant frequency f0 is calculated. When the resonant frequency f0 reaches the frequency band of the first preset frequency band signal, the control module can control the first antenna to transmit or receive the first preset frequency band signal; when the resonant frequency f0 reaches the frequency band of the second preset frequency band signal, the control module can control the second antenna to transmit or receive the second preset frequency band signal.

[0073] In the present application, in the case where the first antenna and / or the second antenna are required to transmit or receive a signal of a specific wavelength, the control module can determine the frequency band of the first preset frequency band signal received and transmitted by the first antenna and the frequency band of the second preset frequency band signal received and transmitted by the second antenna through the speed of light calculation formula. The speed of light calculation formula can be C=λf, where λ is the wavelength of the radio frequency signal and f is the frequency of the radio frequency signal. For example, if the first antenna is required to transmit a signal with a wavelength of λ0, λ0 can be substituted into the formula C=λf to calculate the transmission frequency f0=C / λ0, and the control module can substitute the transmission frequency f0 into the formula The product value of the inductance and capacitance corresponding to the equivalent circuit of the LC resonant circuit is calculated, and then the inductance and capacitance in the LC resonant circuit of the antenna are respectively adjusted to inductance and capacitance values that achieve the product value. In this way, the transmission frequency of the first antenna can reach f0, and the control module can control the first antenna to transmit a signal with a frequency of f0 and a wavelength of λ0.

[0074] Figure 5 Schematic diagram showing an application scenario of the antenna system provided in the embodiment of the present application. Figure 5 As shown, the antenna system can be applied to electronic devices, combined with Figure 5 , the antenna system can be applied to the notebook computer 500 . Figure 5 In the embodiment, the antenna system can be arranged under the C-surface 510 of the laptop computer 500. The C-surface 510 refers to the keyboard surface of the laptop computer 500. The first plane of the antenna substrate covered with copper metal material can serve as an isolation wall, which can isolate the electromagnetic interference between the first antenna and the second antenna in the FPC tetrahedron. Figure 5 As shown, laptop computer 500 includes a recess below region 501, which can be used to install an antenna system. For example, an FPC tetrahedron, which includes the various components of the antenna system of the present application, can be installed in the recess below region 501. After the FPC tetrahedron is installed in the recess below region 501, the isolation wall of the FPC tetrahedron is perpendicular to the C-plane 510.

[0075] like Figure 5As shown, when copper metal material is laid on the first plane to form an isolation barrier, the isolation barrier is usually located below the keyboard surface near the edge of the screen in the laptop 500, and the input and output interfaces in the laptop are mostly set on the side near the edge of the screen below the keyboard surface. For example, the power interface can usually be set on the side near the edge of the screen below the keyboard surface. Therefore, since the isolation barrier and the input / output interface are relatively close in position in the laptop, the isolation barrier can isolate the unidirectional noise signal of the data transmission interface, thereby achieving a noise reduction effect. The isolation barrier can also reduce the impact of the electromagnetic interference signal generated by the data transmission interface on the normal transmission and reception of the first antenna and the second antenna. The distance between the router and the isolation barrier is usually large. Therefore, the isolation strength of the isolation barrier on the omnidirectional signal of the router is relatively small, so it does not affect the normal transmission and reception of the router signal by the antenna.

[0076] Figure 6 FIG. 1 shows a schematic structural diagram of an FPC tetrahedron provided in an embodiment of the present application. Figure 6 As shown, the first antenna 102 is configured on one side of the third plane of the FPC tetrahedron 200, and the second antenna 103 is configured on the other side of the third plane. The plane of the FPC tetrahedron 200 that is opposite and parallel to the third plane on which the first antenna 102 and the second antenna 103 are configured is the first plane. Metal copper can be laid on the first plane. After the metal copper is laid on the first plane of the FPC tetrahedron 200, an isolation barrier is formed. Figure 6 As shown, first interference signal 601 refers to the interference signal generated by the signal transmitted and / or received by first antenna 102 on the signal transmitted and / or received by second antenna 103, and second interference signal 602 refers to the interference signal generated by the signal transmitted and / or received by second antenna 103 on the signal transmitted and / or received by first antenna 102. The isolation barrier can reflect the portion of electromagnetic waves transmitted in the direction of second antenna 103 from the signal transmitted and / or received by first antenna 102, thereby reducing the electromagnetic waves received by second antenna 103 from the first antenna 102. In addition, the isolation barrier can also reflect the portion of electromagnetic waves transmitted in the direction of first antenna 102 from the signal transmitted and / or received by second antenna 103, thereby reducing the electromagnetic waves received by first antenna 102 from second antenna 103. This achieves isolation of the signal transmitted and / or received by first antenna 102 from the signal transmitted and / or received by second antenna 103, weakening electromagnetic interference 601 and electromagnetic interference 602, thereby reducing the electromagnetic interference between first antenna 102 and second antenna 103.

Figure 7 (b) in the figure shows the change curve of the isolation of high frequency signals when the antenna system provided by the embodiment of the present application is not applied. In the antenna system provided by the embodiment of the present application, the first plane of the antenna substrate is paved with copper metal material to form an isolation barrier. Figure 7 In the experiment, by using antenna to simulate interference source, we get Figure 7 The isolation change curve shown in (a) and Figure 7 The change curve of isolation shown in (b) is shown in FIG. Figure 7 (a) shows a curve showing a change in isolation between high-frequency signals transmitted and / or received by the first antenna and the second antenna under the action of the isolation barrier. Figure 7 (b) shows a curve showing the change in isolation between the high-frequency signals transmitted and / or received by the first antenna and the second antenna in the absence of an isolation barrier.

[0078] Figure 7 The horizontal axis of (a) and (b) represents frequency, and the unit of frequency is gigahertz (GHz). Figure 7 The vertical axis in (a) and (b) represents isolation, and the unit of isolation is decibel (dB).

[0079] Figure 7 In (a), the frequency of point M1 on the isolation change curve is 2.400000 GHz, the isolation at point M1 is -28.8428 dB, the frequency of point M2 is 2.450000 GHz, the isolation at point M2 is -25.8105 dB, the frequency of point M3 is 2.500000 GHz, the isolation at point M3 is -25.4511 dB, the frequency of point M4 is 5.150000 GHz, the isolation at point M4 is -35.7983 dB, the frequency of point M5 is 5.350000 GHz, the isolation at point M5 is -38. 6189dB, the frequency at point M6 is 5.470000GHz, the isolation at point M6 is -37.7929dB, the frequency at point M7 is 5.725000GHz, the isolation at point M7 is -45.5812dB, the frequency at point M8 is 5.850000GHz, the isolation at point M8 is -37.8679dB, the frequency at point M9 is 5.925000GHz, the isolation at point M9 is -36.0744dB, the frequency at point M10 is 7.125000GHz, and the isolation at point M10 is -45.4131dB.

[0080] Figure 7In (b), the frequency of point M11 on the isolation change curve is 2.400000 GHz, the isolation at point M11 is -24.0985 dB, the frequency of point M12 is 2.450000 GHz, the isolation at point M12 is -22.6443 dB, the frequency of point M13 is 2.500000 GHz, the isolation at point M13 is -22.7319 dB, the frequency of point M14 is 5.150000 GHz, the isolation at point M14 is -38.2270 dB, the frequency of point M15 is 5.350000 GHz, the isolation at point M15 is -35 .2471dB, the frequency at point M16 is 5.470000GHz, the isolation at point M16 is -35.3084dB, the frequency at point M17 is 5.725000GHz, the isolation at point M17 is -35.8403dB, the frequency at point M18 is 5.850000GHz, the isolation at point M18 is -43.2849dB, the frequency at point M19 is 5.925000GHz, the isolation at point M19 is -47.9719dB, the frequency at point M20 is 7.125000GHz, and the isolation at point M20 is -34.4704dB.

[0081] like Figure 7 As shown in (a) and (b), Figure 7 The frequency of the isolation change curve from point M1 to point M10 in (a) is Figure 7 The frequencies of points M11 to M20 on the isolation variation curve in (b) correspond to the same frequencies. Figure 7 The isolation ratio corresponding to most points on the curve (a) is Figure 7 The points on the curve (b) at the same frequency correspond to smaller isolation, and smaller isolation indicates weaker signal interference in the antenna system. Therefore, it can be seen that the antenna system provided in the embodiment of the present application can isolate signal interference between antennas through the isolation barrier, thereby improving signal quality.

[0082] Figure 8 A schematic diagram showing the change in the amplitude of the interference signal received by the antenna is shown, where: Figure 8 (a) shows a curve showing a change in the amplitude of the interference signal received by the antenna when the antenna system provided in the embodiment of the present application is not applied. Figure 8 (b) in the figure illustrates a curve showing a change in the amplitude of an interference signal received by an antenna when the antenna system provided by an embodiment of the present application is applied. Figure 8 The horizontal axis of (a) and (b) represents frequency, and the unit of frequency is megahertz (MHz). Figure 8 The vertical axis in (a) and (b) represents amplitude, and the unit of isolation is decibel (dB).

[0083] Figure 8 Curve 801 in (a) shows the curve of the change of the amplitude of the interference signal received by the antenna with frequency under normal circumstances when the antenna system provided by the embodiment of the present application is not applied, and curve 802 shows the curve of the change of the amplitude of the interference signal with the maximum amplitude that the antenna can withstand with frequency when the antenna system provided by the embodiment of the present application is not applied. Figure 8 Curve 803 in (b) shows the curve of the change of the amplitude of the interference signal received by the antenna with frequency under normal circumstances when the antenna system provided by the embodiment of the present application is applied, and curve 804 shows the curve of the change of the amplitude of the interference signal with the maximum amplitude that the antenna can withstand when the antenna system provided by the embodiment of the present application is applied.

[0084] Compare Figure 8 From the curve 802 and the curve 804, we can see that at the same frequency, the maximum amplitude of the interference signal that the antenna of the antenna system can withstand is basically the same. Figure 8 As can be seen from curves 801 and 803, at the same frequency, the amplitude of the interference signal received by the antenna using the antenna system provided by the embodiment of the present application is generally smaller than the amplitude of the interference signal received by the antenna not using the antenna system provided by the embodiment of the present application, and is also much smaller than the maximum amplitude of the interference signal that the antenna of the antenna system can withstand. The amplitude of the interference signal received by the antenna using the antenna system provided by the embodiment of the present application is generally less than -105dB, and the amplitude of the interference signal received by the antenna not using the antenna system provided by the embodiment of the present application is generally not higher than -101dB. By comparison, it can be seen that the amplitude of the interference signal received by the antenna using the antenna system provided by the embodiment of the present application is smaller, and the antenna system is more stable.

[0085] Figure 9 A schematic diagram showing the change of antenna gain of the antenna system provided in an embodiment of the present application is shown. Figure 9 The horizontal axis represents frequency, and the unit of frequency is gigahertz (GHz). Figure 9 The vertical axis represents gain, and the unit of isolation is decibel (dB). Figure 9 The curve 901 in FIG. 1 shows a curve showing how the gain of the first antenna in the antenna system changes with frequency. Figure 9 Curve 902 in FIG. 1 shows a curve of how the gain of the second antenna in the antenna system changes with frequency. Figure 9 The specific values of the gain of the first antenna represented by curve 901 and the gain of the second antenna represented by curve 902 at the same frequency can be referred to Table 1.

[0086] Table 1: Antenna gain table

[0087]

[0088]

[0089] The medium and low frequencies in this application refer to frequency bands less than or equal to 3 GHz, and the high frequencies in this application refer to frequency bands higher than 3 GHz.

[0090] Reference Figure 9 Compared with Table 1 above, it can be seen that the gain of the first antenna is slightly higher than that of the second antenna after 5.75 GHz, and the gain of the first antenna is slightly lower than that of the second antenna before 2.45 GHz. In other words, in this application, the gain of the first antenna is slightly lower than that of the second antenna at medium and low frequencies, and slightly higher than that of the second antenna at high frequencies. However, overall, the gain of the first antenna and the gain of the second antenna in the antenna system of this application are both relatively high. In other words, the antenna system of this application reduces the electromagnetic interference between the first antenna and the second antenna by isolating the retaining wall, thereby increasing the gain of the first antenna and the overall gain of the second antenna.

[0091] Figure 10 A schematic diagram of the 2D field pattern of the antenna of the antenna system provided in an embodiment of the present application is shown. Figure 10 (a) and (e) in the figure respectively illustrate the 2D field pattern of the first antenna and the 2D field pattern of the second antenna at a frequency of 2.450 GHz. Figure 10 (b) and (f) in the figure respectively show the 2D field pattern of the first antenna and the 2D field pattern of the second antenna at a frequency of 5.470 GHz. Figure 10 (c) and (d) in the figure respectively illustrate the 2D field pattern of the first antenna and the 2D field pattern of the second antenna at a frequency of 6.525 GHz. Figure 10 Where deg represents the radiation angle of the antenna in the 2D field. Figure 10 As shown, a radiation axis can be set every 30° in each 2D field pattern. Figure 10 The radiation axis with the center of the circle pointing to each radiation angle in each 2D field diagram represents the radiation intensity in decibels (dB).

[0092] Figure 11 A schematic diagram of the 3D field pattern of the antenna of the antenna system provided in an embodiment of the present application is shown. Figure 11 (a) and (e) in the figure respectively illustrate the 3D field pattern of the first antenna and the 3D field pattern of the second antenna at a frequency of 2.450 GHz. Figure 11 (b) and (f) in the figure respectively show the 3D field pattern of the first antenna and the 3D field pattern of the second antenna at a frequency of 5.470 GHz. Figure 11 (c) and (d) in the figure respectively illustrate the 3D field pattern of the first antenna and the 3D field pattern of the second antenna at a frequency of 6.525 GHz.

[0093] like Figure 10 As shown, the first antenna and the second antenna in the antenna system of the present application have a relatively uniform radiation intensity distribution at each radiation angle at high frequencies such as 5.470 GHz and 6.525 GHz and medium and low frequencies such as 2.450 GHz. The width of the radiation main lobe in the X direction is large, the radiation intensity distribution is relatively uniform, and the radiation intensity is high. The radiation intensity distribution in the Y direction is also relatively uniform. Figure 11 As shown, the first and second antennas in the antenna system of the present application have higher radiation intensity in the x-direction at low- to mid-frequency bands like 2.450 GHz, and higher radiation intensity in the y- and z-directions at high frequencies like 5.470 GHz and 6.525 GHz. The radiation intensity distribution of the first and second antennas is relatively uniform at both low- and mid-frequency bands. This verifies that the isolation barrier in the antenna system of the present application only isolates most interference signals and does not affect the normal transmission and reception of the first and second antennas.

[0094] The present application also provides a signal processing method. The signal processing method is applied to a control module in an antenna system, wherein the antenna system further includes an antenna substrate, a first antenna, and a second antenna. The signal processing method may include steps A1-A2:

[0095] Step A1: Obtain signal processing instructions.

[0096] In this application, signal processing instructions may include signal transmission instructions and signal reception instructions. The control module may receive signal processing instructions sent by a signal monitoring sensor or processor of an electronic device via a communication protocol. For example, if an electronic device can send a signal transmission instruction to send a signal to another device to the control module, the monitoring sensor may send a signal reception instruction to the control module after detecting a signal sent by a user terminal to the electronic device.

[0097] Step A2: Based on the signal processing instruction, control at least one of the first antenna and the second antenna to receive and / or transmit the target signal.

[0098] In the present application, the target signal is a signal that needs to be transmitted or received by the first antenna or the second antenna. The signal processing instruction may include the frequency band information of the target signal, the antenna identification of the target signal used for transmission or reception, and the signal processing type information. The signal processing type may include transmitting a signal or receiving a signal. The antenna identification may include the identification of the first antenna of the antenna system or the identification of the second antenna. For example, the signal processing instruction includes: the identification of the first antenna, the frequency band of the target signal is 2.4 GHz, and the signal processing type is a transmitting signal. The control module can then obtain the frequency band of the target signal that needs to be transmitted by the first antenna according to the signal processing instruction, and according to the frequency band and the formula Determine the inductance and capacitance of the LC resonant circuit, and adjust the inductance and capacitance of the LC resonant circuit to the inductance and capacitance, so that the signal transmission frequency of the first antenna reaches the frequency band, thereby controlling the first antenna to transmit the target signal. The method for determining the inductance and capacitance of the LC resonant circuit can refer to the relevant description in the above antenna system, which will not be repeated here.

[0099] In this application, the first plane of the antenna substrate is configured with a target metal material for reflecting electromagnetic waves from at least one of the first and second antennas. The second and / or third planes of the antenna substrate are configured with a first antenna for transmitting a signal in a first preset frequency band and a second antenna for transmitting a signal in a second preset frequency band. Specifically, the antenna substrate comprises a first plane, a second plane, a third plane, and a fourth plane. The first plane is paved with the target metal material, and the fourth plane is grounded. The first antenna is configured on the second and / or third planes of the antenna substrate and is configured to transmit a signal in the first preset frequency band. The second antenna is configured on the second and / or third planes of the antenna substrate and is configured to transmit a signal in the second preset frequency band. The first antenna is different from the second antenna. The first and second planes are adjacent and perpendicular to each other, the second and third planes are adjacent and perpendicular to each other, and the first and third planes are opposite and parallel to each other. The antenna substrate also includes a fourth plane. The fourth plane is grounded, adjacent and perpendicular to the first plane, adjacent and perpendicular to the third plane, and opposite and parallel to the second plane.

[0100] In the present application, if the first antenna and the second antenna are configured on the same plane of the antenna substrate, the distance between the first antenna and the second antenna is greater than the first preset coupling distance; if the first antenna and the second antenna are respectively configured on different planes of the antenna substrate, the distance between the first antenna and the second antenna is greater than the second preset coupling distance, and the first preset coupling distance is greater than the second preset coupling distance.

[0101] In the present application, the target metal material may include copper. The target metal material may also include metal materials such as nickel that can isolate electromagnetic interference.

[0102] In the present application, the first preset frequency band signal includes a 2.4G frequency band signal, a 5G frequency band signal, and a 6G frequency band signal; the second preset frequency band signal includes a 2.4G frequency band signal, a 5G frequency band signal, and a 6G frequency band signal.

[0103] In the present application, the first antenna and the second antenna are arranged on the second plane and / or the third plane of the antenna substrate through a target fixture.

[0104] In an optional implementation, the first antenna is configured in a first groove of the antenna substrate. The first groove is a region recessed from the second plane or the third plane toward the inside of the antenna substrate. The size of the first groove matches the size of the first antenna.

[0105] In an optional implementation, the second antenna is configured in a second groove of the antenna substrate. The second groove is a region recessed from the second plane or the third plane toward the inside of the antenna substrate. The size of the second groove matches that of the second antenna.

[0106] Using the signal processing method provided in this application, a first antenna and / or a second antenna are configured on the second plane and / or the third plane of the antenna substrate, and a target metal material for reflecting electromagnetic waves from at least one of the first and second antennas is laid on the first plane of the antenna substrate. The first plane on which the target metal material is laid can serve as an isolation barrier, reflecting electromagnetic waves generated when each antenna of the antenna system transmits or receives signals that would interfere with other antennas in the antenna system, thereby reducing the probability that other antennas will be interfered with by the electromagnetic waves of the antenna. In other words, the first plane on which the target metal material is laid can improve the isolation between the first and second antennas, reduce the electromagnetic interference between the first and second antennas, and thus improve the performance of the antenna in transmitting and receiving signals. In addition, by configuring the first antenna, the second antenna, and the target metal material on the antenna substrate structure, there is no need to add additional interference reduction structures, which can achieve the goal of reducing electromagnetic interference while reducing noise reduction costs.
