Description

Technical Field

[0001] This application relates to the field of antenna technology, and in particular to an electronic device. Background Technology

[0002] With the development and advancement of technology, mobile communication technology has gradually been applied to electronic devices, such as mobile phones and front-end devices. Generally, to improve the communication performance of electronic devices, an external antenna is installed on the device's casing. In addition, to deploy an external antenna, an antenna interface needs to be provided on the electronic device, and a corresponding antenna adapter needs to be installed on the external antenna side.

[0003] During the deployment of external antennas, an antenna adapter needs to be inserted into the antenna interface to ensure that electronic devices can communicate using the external antenna. However, during deployment, the external adapter and antenna interface must be aligned before insertion. Furthermore, if the antenna adapter is not fully inserted or is over-inserted, the communication performance of the external antenna will be affected. Therefore, how to effectively deploy external antennas is a problem that urgently needs to be solved. Summary of the Invention

[0004] This application provides an electronic device that can quickly and effectively deploy an external antenna while ensuring the communication performance of the external antenna.

[0005] An electronic device includes: a housing, a first antenna, a first coupling module, a second coupling module, and a radio frequency processing module, wherein...

[0006] The first antenna is disposed outside the housing;

[0007] The first coupling module is electrically connected to the first antenna and is disposed outside the housing;

[0008] The second coupling module is disposed on the inner wall of the housing and can be capacitively coupled to the first coupling module;

[0009] The radio frequency processing module is electrically connected to the second coupling module and is used to radiate electromagnetic wave signals through the first antenna when the first coupling module and the second coupling module are capacitively coupled.

[0010] The aforementioned electronic device includes a housing, a first antenna, a first coupling module, a second coupling module, and a radio frequency processing module. The first antenna is electrically connected to the first coupling module and is disposed outside the housing. The second coupling module is disposed on the inner wall of the housing and is capacitively coupled to the first coupling module. With the first and second coupling modules capacitively coupled, electromagnetic wave signals are radiated through the first antenna. In this embodiment, when deploying the first antenna (i.e., the external antenna), the electronic device only needs to move the position of the first coupling module or the housing to capacitively couple the first and second coupling modules, thus achieving an electrical connection between the radio frequency processing module and the first antenna to transmit AC signals and radiate electromagnetic wave signals. Clearly, deploying the first antenna avoids the need for antenna interfaces and adapters, as well as related insertion actions, preventing damage to other components of the electronic device. This simplifies the deployment complexity of the external antenna, improves its usability, and ensures its communication performance while allowing for quick and effective deployment.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] It is understood that the terms "first," "second," etc., used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, without departing from the scope of this application, the first coupling module 12 may be referred to as the second coupling module 13, and similarly, the second coupling module 13 may be referred to as the first coupling module 12. Both the first coupling module 12 and the second coupling module 13 are coupling modules, but they are not the same coupling module. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] This application provides an electronic device 10, which can specifically be a user equipment (UE), access terminal, terminal unit, terminal station, mobile station, mobile station, remote station, remote terminal, mobile device, wireless communication device, terminal agent, or terminal device, etc. The access terminal can be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), computer, laptop computer, handheld computing device, and / or other devices used for communication over a wireless system. This application uses Customer Premise Equipment (CPE) as an example for illustration. The CPE is used to implement network access functions, converting the operator's public network (WAN) to the user's home local area network (LAN). Current internet broadband access methods can be categorized as fiber optic access, digital telephone line access, cable TV line access, and mobile access (i.e., wireless CPE), etc. A customer front-end device (FPS) is a mobile signal access device that receives mobile signals and forwards them as Wi-Fi signals. It also converts high-speed 4G or 5G signals into Wi-Fi signals, supporting simultaneous network access for multiple mobile devices (such as mobile phones and tablets). FPSs can be installed indoors or outdoors. For clarity, this explanation will focus on an indoor FPS installation.

[0026] refer to Figure 1 In one embodiment, the electronic device 10 includes a housing 11 and a circuit board. The housing 11 defines a mounting cavity, and the circuit board is mounted in the mounting cavity, with the housing 11 providing support, positioning, and protection. Figure 1 In the illustrated embodiment, the housing 11 is generally cylindrical, and the appearance of the electronic device 10 is primarily represented by the housing 11. In other embodiments, the housing 11 may have other shapes, such as prisms. The circuit board has multiple interfaces 15 exposed to the housing 11, and these interfaces 15 are electrically connected to the circuit board. Figure 1In the illustrated embodiment, interface 15 includes a power interface 151, a network cable interface 153, a USB interface 155, etc. The power interface 151 is used to connect to an external power source to power the electronic device 10. The USB interface 155 is used for data transmission between the electronic device 10 and external devices. Of course, the USB interface 155 and the power interface 151 can be integrated into one unit to simplify the arrangement of interfaces 15 on the electronic device 10. The network cable interface 153 may further include a wired network access port and a wired network output port. The electronic device 10 can connect to the network through the wired network access port and then connect to other devices through one or more wired network output ports. Of course, in some embodiments, the wired network output port can be omitted; that is, after the electronic device 10 connects to the network using the wired network input port, the RF module integrated in the housing 11 can convert the wired network into a wireless network (e.g., WIFI) for external devices to access the network. Of course, both the wired network access point and the wired network output point can be omitted. In this implementation, the electronic device 10 can access the cellular network (also known as the mobile network) through the radio frequency system and then convert it into a WiFi signal for external devices to access the network.

[0027] refer to Figure 1 The housing 11 may also be equipped with a button 16 or similar structure, which is used to control the operating status of the electronic device 10. For example, the user can press the button 16 to turn the electronic device 10 on or off. Of course, the housing 11 may also be equipped with indicator lights or other devices to indicate the operating status of the electronic device 10.

[0028] like Figure 2 As shown, the electronic device 10 also includes a first antenna ANT1, a first coupling module 12, and a radio frequency processing module 14 and a second coupling module 13 disposed within the housing 11. The first antenna ANT1 is disposed outside the housing 11 of the electronic device 10 and can be understood as an external antenna. The first antenna ANT1 can be a single-frequency antenna or a multi-band antenna. The first antenna ANT1 can be a directional antenna or an omnidirectional antenna. The first antenna ANT1 can support the radiation of at least one of 2G, 3G, 4G, and 5G signals. It can be understood that radiation can refer to the reception of a signal, the transmission of a signal, or both. Optionally, the electronic device 10 may also include at least one second antenna ANT2 built into the housing 11 to support the radiation of electromagnetic wave signals.

[0029] The first coupling module 12 is electrically connected to the first antenna ANT1 and is disposed outside the housing 11. The first coupling module 12 and the first antenna ANT1 can be fixedly connected or detachably connected. The first coupling module 12 and the first antenna ANT1 can also be integrally formed. In the embodiments of this application, the connection method between the first coupling module 12 and the first antenna ANT1 is not further limited.

[0030] The second coupling module 13 is disposed on the inner wall of the housing 11. For example, the second coupling module 13 can be attached to the inner wall of the housing 11, or the second coupling module 13 can be embedded in the housing 11. The first coupling module 12 and the second coupling module 13 are disposed separately, and there is no direct or indirect wire connection or interface connection between them. The position of the electronic device 10 and the position of the first coupling module 12 have a following relationship. For example, when the first coupling module 12 and the first antenna ANT1 are fixedly disposed in a position independent of the location of the electronic device 10, the electronic device 10 can be moved to the location of the first coupling module 12, so that the first coupling module 12 and the second coupling module 13 can be coupled to each other to achieve capacitive coupling. Optionally, when the electronic device 10 is fixedly disposed in a position independent of the location of the first coupling module 12, the first coupling module 12 can be moved to the location of the electronic device 10, so that the first coupling module 12 and the second coupling module 13 can be coupled to each other to achieve capacitive coupling.

[0031] The radio frequency processing module 14, disposed within the housing 11, is electrically connected to the second coupling module 13. With the first coupling module 12 and the second coupling module 13 capacitively coupled, they can be considered equivalent to a capacitor. It is understood that with the first coupling module 12 and the second coupling module 13 capacitively coupled, alternating current signals can be transmitted, allowing the radio frequency processing module 14 to be electrically connected to the first antenna ANT1 externally located within the housing 11, thereby supporting the first antenna ANT1 in radiating electromagnetic wave signals. Exemplarily, the radio frequency processing module 14 may include at least one receiving circuit for supporting the reception of electromagnetic wave signals and a transmitting circuit for supporting the transmission of electromagnetic wave signals.

[0032] The aforementioned electronic device 10 includes a housing 11, a first coupling module 12 and a first antenna ANT1 disposed outside the housing 11, and a second coupling module 13 and a radio frequency processing module 14 disposed inside the housing 11. When the first coupling module 12 and the second coupling module 13 are capacitively coupled, the radio frequency processing module 14 is electrically connected to the antenna to radiate electromagnetic wave signals through the first antenna ANT1. In this embodiment, when deploying the first antenna ANT1 (i.e., the external antenna), the electronic device 10 only needs to move the position of the first coupling module 12 or the housing 11 to capacitively couple the first coupling module 12 and the second coupling module 13. This achieves the electrical connection between the radio frequency processing module 14 and the first antenna ANT1 to transmit AC signals and radiate electromagnetic wave signals through the first antenna ANT1. Clearly, the deployment of the first antenna ANT1 avoids the need for antenna interfaces and adapters, as well as related insertion actions, preventing damage to other components of the electronic device 10. This simplifies the deployment complexity of the external antenna, improves its usability, and ensures its communication performance while allowing for quick and effective deployment.

[0033] In one embodiment, to achieve capacitive coupling between the first coupling module 12 and the second coupling module 13, the position of at least one of the first coupling module 12 and the second coupling module 13 can be adjusted to satisfy the condition of overlapping projected areas for capacitive coupling. This overlapping condition means that the orthographic projection of the first coupling module 12 onto the plane of the housing 11 at least partially overlaps with the orthographic projection of the second coupling module 13 onto the plane of the housing 11. It is understood that when the orthographic projection of the first coupling module 12 onto the plane of the housing 11 at least partially overlaps with the orthographic projection of the second coupling module 13 onto the plane of the housing 11, the first coupling module 12 and the second coupling module 13 are capacitively coupled to generate capacitance. The overlapping area and the thickness of the housing 11 affect the capacitance value generated during the capacitive coupling of the first coupling module 12 and the second coupling module 13. The formula for the capacitance value is:

[0034] C=εs / 4πkd

[0035] In the formula, d is the distance between the first coupling module 12 and the second coupling module 13; s is the overlapping area of ​​the projection of the first coupling module 12 and the second coupling module 13 onto the plane of the housing 11; ε is the dielectric constant, which is related to the filling material between the first coupling module 12 and the second coupling module 13.

[0036] In this embodiment, d and ε depend on whether the first antenna ANT1 and the housing 11 of the electronic device 10 are located in the same free space. When the free space is indoors, d depends on the thickness of the housing 11 of the electronic device 10, and ε depends on the material of the housing 11 and the air. When the first antenna ANT1 and the housing 11 of the electronic device 10 are located in two separate free spaces, for example, the housing 11 of the electronic device 10 is located in an indoor free space, while the first antenna ANT1 is located in an outdoor free space, then d depends on the thickness of the housing 11 of the electronic device 10 and the thickness of the conductive medium 20, and ε depends on the material of the housing 11, the material of the conductive medium 20, and the air. The conductive medium 20 is the medium that separates the indoor and outdoor free spaces. The conductive medium 20 can be a wall, window, etc. Whether the first antenna ANT1 and the housing 11 of the electronic device 10 are located in the same free space can be set according to different requirements. Furthermore, the specific arrangements for the first antenna ANT1 and the housing 11 of the electronic device 10 being located in the same free space, and for the first antenna ANT1 and the housing 11 of the electronic device 10 not being located in the same free space, will be described in detail later.

[0037] In this embodiment, since the first coupling module 12 and the first antenna ANT1 are directly electrically connected, and the first coupling module 12 and the second coupling module 13 are discrete designs, when the electronic device 10 has a communication requirement with an external antenna, at least one of the electronic device 10 and the first coupling module 12 can be moved to satisfy the projected area overlap condition for capacitive coupling. This allows the RF processing module 14 within the electronic device 10 to transmit electrical signals with the first antenna ANT1, thereby enabling communication through the first antenna ANT1. If the electronic device 10 does not have a communication requirement with an external antenna, at least one of the electronic device 10 and the first coupling module 12 can also be moved to prevent the projected area overlap condition for capacitive coupling from being met. This prevents the RF processing module 14 within the electronic device 10 from transmitting electrical signals with the first antenna ANT1, putting both the RF processing module 14 and the first antenna ANT1 into a dormant state, reducing power consumption and increasing the lifespan of related devices.

[0038] like Figure 3 As shown, in one embodiment, the first coupling module 12 may include a first electrode plate 121, and the second coupling module 13 may include a second electrode plate 131. Wherein, when the orthographic projection of the first electrode plate 121 onto the plane of the housing 11 at least partially coincides with the orthographic projection of the second electrode plate 131 onto the plane of the housing 11, the first electrode plate 121 and the second electrode plate 131 are equivalent to capacitors.

[0039] The first electrode plate 121 and the second electrode plate 131 can be made of metal plates, copper foil plates, or other conductive materials, respectively. The shapes of the first electrode plate 121 and the second electrode plate 131 can be the same or different. The shapes of the first electrode plate 121 and the second electrode plate 131 can be rectangular, rounded rectangular, circular, elliptical, irregular, etc. To achieve better capacitive coupling, the first electrode plate 121 and the second electrode plate 131 can be made of the same material and have the same shape. For example, both the first electrode plate 121 and the second electrode plate 131 can be rectangular metal plates. It should be noted that in this embodiment, the shape and material of the first electrode plate 121 and the second electrode plate 131 are not limited to the examples described above, and can be adjusted according to the communication requirements of the electronic device 10.

[0040] Optionally, the first electrode plate 121 and the first antenna ANT1 can be made of the same material and can be integrally formed. For example, the first antenna ANT1 can be a metal branch extending outward from the first electrode plate 121. In this way, the first electrode plate 121 and the first antenna ANT1 are integrally formed, which can simplify the installation structure between the first electrode plate 121 and the first antenna ANT1 and also reduce costs.

[0041] As mentioned in the foregoing embodiments, the first coupling module 12 is disposed outside the housing 11. In one embodiment of this application, the first electrode plate 121 of the first coupling module 12 is detachably connected to the outer wall of the housing 11. The following describes two specific application scenarios:

[0042] Application Scenario 1: The first antenna ANT1 and the housing 11 of the electronic device 10 are both located in the same free space. Please refer to [further details]. Figure 3 This same free space can be either indoor or outdoor.

[0043] In this application scenario, the first electrode plate 121 in the first coupling module 12 can be configured to connect with the outer wall of the housing 11 according to the communication requirements of the electronic device 10. The second electrode plate 131 in the second coupling module 13 can be disposed on the inner wall of the housing 11. When the electronic device 10 has a communication requirement with an external antenna, the first electrode plate 121 in the first coupling module 12 can be disposed on the outer wall of the housing 11, ensuring that the relative positions of the first electrode plate 121 and the second electrode plate 131 meet the condition of overlapping projected areas for capacitive coupling. This allows the radio frequency processing module 14 disposed within the housing 11 to transmit AC signals with the first antenna ANT1, thereby enabling the radiation of electromagnetic signals through the first antenna ANT1.

[0044] Optionally, when the electronic device 10 does not require communication via an external antenna, the first electrode plate 121 can be removed from the outer wall of the housing 11, so that the relative positions of the first electrode plate 121 and the second electrode plate 131 do not meet the condition of overlapping projected areas for capacitive coupling. In this case, the radio frequency processing module 14 housed within the housing 11 cannot transmit AC signals with the first antenna ANT1. Both the radio frequency processing module 14 and the first antenna ANT1 are in a dormant state, which reduces power consumption and extends the lifespan of related components.

[0045] Application Scenario 2: The first antenna ANT1 and the housing 11 of the electronic device 10 are located in different free spaces. For example, the housing 11 of the electronic device 10 is located in indoor free space, and the first antenna ANT1 is located in outdoor free space. Figure 4 As shown, the indoor free space and the outdoor free space can be separated by a conductive medium 20, which can be a wall, window, etc.

[0046] Outdoor base stations that also provide indoor coverage offer advantages such as rapid network deployment and low investment costs, making them a common form of indoor coverage in the early stages of network construction. Outdoor coverage for indoor use is primarily suitable for single-story buildings with small floor areas and building materials easily penetrated by wireless signals. 5G uses higher frequency spectra to obtain wider bandwidth resources; however, the propagation characteristics of wireless signals mean that higher frequencies experience greater spatial loss during propagation and greater penetration loss through building materials, affecting their ability to provide deep indoor coverage. According to propagation model calculations, at the same distance: 2600MHz has approximately 4.5dB higher path loss than 1800MHz; 3500MHz has approximately 2.5dB higher path loss than 2600MHz. Test data on penetration loss of different frequency bands to building materials are shown in Table 1.

[0047] Table 1 shows the penetration loss test data of building materials at different frequency bands.

[0048] category 1800 / 2100MHz 2600MHz 3500MHz Brick wall penetration loss (dB) 10-15 11-18 12-20 Concrete penetration loss (dB) 20-30 22-32 25-35 Penetration loss of gypsum board (dB) 8-12 9-14 10-15 Penetration loss (dB) of ordinary glass wall 2-5 4-6 5-8 Penetration loss (dB) of thin wooden doors 3-5 5-7 5-8

[0049] To overcome the losses caused by wall penetration, in this embodiment, the first antenna ANT1 is placed in outdoor free space. In this application scenario, the first antenna ANT1 can be referred to as the outdoor antenna to reduce the losses caused by wall penetration and thus improve communication performance. Specifically, the first electrode plate 121 can be fixed to the outside of the wall, and the first antenna ANT1 is fixed on the first electrode plate 121. The second electrode plate 131 can be fixed to the inner wall of the housing 11 of the electronic device 10. When the electronic device 10 has a communication requirement with an external antenna, the housing 11 of the electronic device 10 can be moved so that the relative positions of the first electrode plate 121 and the second electrode plate 131 meet the condition of overlapping projected areas for capacitive coupling. In this way, the radio frequency processing module 14 disposed in the housing 11 can transmit AC signals with the first antenna ANT1, and then radiate electromagnetic wave signals through the first antenna ANT1.

[0050] Optionally, when the electronic device 10 does not require communication via an external antenna, the housing 11 of the electronic device 10 can be moved so that the relative positions of the first electrode plate 121 and the second electrode plate 131 do not meet the condition of overlapping projected areas for capacitive coupling. In this case, the radio frequency processing module 14 housed within the housing 11 cannot transmit AC signals with the first antenna ANT1. Both the radio frequency processing module 14 and the first antenna ANT1 are in a dormant state, which reduces power consumption and extends the lifespan of related components.

[0051] In this embodiment, by setting the first coupling module 12 and the first antenna ANT1 in outdoor free space, the first antenna ANT1 is used as an outdoor antenna. When the first antenna ANT1 is connected to the radio frequency processing module 14 in the electronic device 10, it is only necessary to move the position of the housing 11 of the electronic device 10 to capacitively couple the first coupling module 12 and the second coupling module 13, so that the radio frequency processing module 14 and the first antenna ANT1 can be electrically connected. There is no need to drill holes in the wall or window, nor is it necessary to set an antenna interface on the electronic device 10 for inserting the antenna. This eliminates the need for professional drilling due to the need for cables to pass through windows or walls, as well as the installation between the first antenna ANT1 and the antenna interface. Electromagnetic wave signals can be radiated through the first antenna ANT1. In this way, the first antenna ANT1 can be deployed quickly and effectively, while reducing the loss caused by passing through walls, thereby improving communication performance.

[0052] like Figure 5As shown, in one embodiment, the first coupling module 12 may optionally include multiple sub-electrodes. For example, the first coupling module 12 may include a first sub-electrode 122, a second sub-electrode 123, and a third sub-electrode 124. The first sub-electrode 122 is disposed on the outer wall of the housing 11 and electrically connected to the second sub-electrode 123. The second sub-electrode 123 and the third sub-electrode 124 are disposed on opposite sides of the conductive medium 20, and the third sub-electrode 124 is electrically connected to the first antenna ANT1. The first sub-electrode 122, the second sub-electrode 123, and the second electrode plate 131 are disposed on the same side of the conductive medium 20. It is understood that the housing 11 of the electronic device 10 and the first sub-electrode 122 and the second sub-electrode 123 in the first coupling module 12 are located in indoor free space, while the third sub-electrode 124, electrically connected to the first antenna ANT1, is located in outdoor free space.

[0053] Furthermore, the second sub-electrode 123 and the third sub-electrode 124 can be fixed on opposite sides of the conductive medium 20, respectively. For ease of explanation, the conductive medium 20 is taken as a wall as an example. The second sub-electrode 123 is fixed to the inner wall of the wall, and the third sub-electrode 124 is fixed to the outer wall of the wall. The relative positional relationship between the second sub-electrode 123 and the third sub-electrode 124 satisfies the condition of coincident projected areas for capacitive coupling. It can be understood that when the orthographic projection of the second sub-electrode 123 onto the plane of the conductive medium 20 at least partially coincides with the orthographic projection of the third sub-electrode 124 onto the plane of the conductive medium 20, the second sub-electrode 123 and the third sub-electrode 124 are capacitively coupled, which can be equivalent to a capacitor, thus generating a capacitor. The second electrode plate 131 is disposed on the inner wall of the housing 11, and the first sub-electrode 122 is disposed on the outer wall of the housing 11. When the orthographic projection of the second electrode plate 131 onto the plane of the housing 11 at least partially coincides with the orthographic projection of the first sub-electrode 122 onto the plane of the housing 11, the second electrode plate 131 and the first sub-electrode 122 are capacitively coupled, which can be equivalent to a capacitor. Since the first sub-electrode 122 and the second sub-electrode 123 are electrically connected, the radio frequency processing module 14 inside the housing 11 can be connected to the first antenna ANT1 via the first capacitor and the second capacitor to realize the transmission of AC signals between the radio frequency processing module 14 and the first antenna ANT1, and thus the electromagnetic wave signal can be radiated through the first antenna ANT1. The first capacitor is the equivalent capacitance formed by the capacitive coupling of the second electrode plate 131 and the first sub-electrode 122, and the second capacitor is the equivalent capacitance formed by the capacitive coupling of the second sub-electrode 123 and the third sub-electrode 124.

[0054] Furthermore, the first sub-electrode 122 can be connected to the second sub-electrode 123 via a wire. The length of the wire can be set according to the distance between the housing 11 of the electronic device 10 and the first antenna ANT1. Connecting the first sub-electrode 122 and the second sub-electrode 123 via a wire can increase the range of motion of the housing 11 of the electronic device 10.

[0055] In one embodiment, in order to facilitate the storage of the wires connecting the first sub-electrode 122 and the second sub-electrode 123, a receiving cavity can be provided in the housing 11 to store the wires used to connect the second sub-electrode 123 and the third sub-electrode 124.

[0056] Optionally, the first sub-electrode 122 is detachably connected to the outer wall of the housing 11.

[0057] Optionally, the second sub-electrode 123 is detachably connected to the inner wall of the conductive medium 20.

[0058] When the electronic device 10 does not require communication with an external antenna, the first sub-electrode 122 can be removed from the outer wall of the housing 11, or the second sub-electrode 123 can be removed from the inner wall of the conductive medium 20. When the electronic device 10 requires communication with an external antenna, the first sub-electrode 122 can be installed in a preset area to meet the projected area overlap condition for capacitive coupling, and the second sub-electrode 123 can be installed in a preset area on the inner wall of the conductive medium 20 to meet the projected area overlap condition for capacitive coupling.

[0059] In this embodiment, by setting one of the two detachable connections—the first sub-electrode 122 being detachably connected to the outer wall of the housing 11, and the second sub-electrode 123 being detachably connected to the inner wall of the conductive medium 20—the configuration can be flexibly adjusted according to the communication requirements of the external antenna, thereby improving the application flexibility of the electronic device 10.

[0060] Optionally, the third sub-electrode 124 is detachably connected to the outer wall of the conductive medium 20. For example, when encountering severe weather in the outdoor free space, such as typhoons, storms, heavy rain, blizzards, or other extreme weather, the third sub-electrode 124 and the first antenna ANT1 can be detached to prevent damage.

[0061] It should be noted that, in this embodiment, the first electrode plate 121, the first sub-electrode 122, the second sub-electrode 123, and the third sub-electrode 124 can be detachably connected to the outer wall of the housing 11 and the inner and outer walls of the conductive medium 20 respectively by means of fasteners, magnetic fasteners, etc. In this embodiment, the specific methods of detachable connection are not limited to the examples described above.

[0062] Optionally, the materials and shapes of the first sub-electrode 122, the second sub-electrode 123, and the third sub-electrode 124 can be referred to the description of the first electrode plate 121 and the second electrode plate 131 above, and will not be repeated here. Optionally, the third sub-electrode 124 and the first antenna ANT1 can be made of the same material and can be integrally formed. For example, the first antenna ANT1 can be a metal branch extending outward from the third sub-electrode 124. In this way, the third sub-electrode 124 and the first antenna ANT1 are integrally formed, which can simplify the installation structure between the third sub-electrode 124 and the first antenna ANT1, and also reduce costs.

[0063] like Figure 6 As shown in the foregoing embodiments, the first coupling module 12 and the second coupling module 13 can constitute a coupling module. In this embodiment, the electronic device 10 may include multiple coupling modules and multiple first antennas ANT1. The second coupling module 13 in each coupling module can be connected to a radio frequency processing module, and the first coupling module 12 in each coupling module can be connected to a corresponding first antenna ANT1, with each first coupling module 12 connected to a different first antenna ANT1. In this embodiment, by setting multiple sets of coupling modules and multiple first antennas ANT1, multiple external antennas can communicate simultaneously, improving the communication performance of the electronic device 10.

[0064] In one embodiment, the housing 11 includes a top plate, a bottom plate, and side plates, which together form a hollow structure with a receiving cavity. The radio frequency processing module 14 is disposed within the receiving cavity, and the second coupling module 13 is disposed on the inner wall of the bottom plate. Thus, when the housing 11 of the electronic device 10 and the first antenna ANT1 are in the same free space, and the electronic device 10 requires communication via an external antenna, the first coupling module 12 can be directly disposed on the outer wall of the bottom plate, satisfying the condition of overlapping projected areas for capacitive coupling. This allows the radio frequency processing module 14 and the first antenna ANT1 to transmit AC signals, and subsequently, electromagnetic wave signals can be radiated through the first antenna ANT1. By disposing of both the first coupling module 12 and the second coupling module 13 on the bottom plate of the housing 11, the first coupling module 12 and the second coupling module 13 can be hidden, making the appearance of the housing 11 more aesthetically pleasing.

[0065] It should be noted that the location of the second coupling module 13 is not limited to the description of the above embodiment. Optionally, the second coupling module 13 can also be located at any position on the inner wall of the housing 11.

[0066] like Figure 7As shown, in one embodiment, the radio frequency processing module 14 includes a coupling detection circuit 141, a processing circuit 142, and a radio frequency circuit 143. The coupling detection circuit 141 is connected to the second coupling module 13 and is used to detect the capacitance information generated when the first coupling module 12 and the second coupling module 13 are capacitively coupled. The coupling detection circuit 141 may include a capacitance sensor. Optionally, the coupling detection circuit 141 may include a magnetic sensor, etc.

[0067] The processing circuit 142 is connected to the coupling detection circuit 141 and the radio frequency circuit 143, respectively, and is used to output a control signal to the radio frequency circuit 143 according to the received capacitance information. The radio frequency circuit 143 can be used to radiate electromagnetic wave signals through the first antenna ANT1 according to the received control signal. The processing circuit 142 may include one of the following: a processor, a baseband processor, and a radio frequency transceiver of the electronic device 10. The processor may be an application processor, etc., in the electronic device 10.

[0068] The radio frequency circuit 143 may include a radio frequency transceiver circuit, which can be used to support the reception and processing of AC signals corresponding to electromagnetic wave signals from the first antenna ANT1, and can also support the transmission and processing of AC signals from the radio frequency transceiver and transmit them to the first antenna ANT1, through which the corresponding electromagnetic wave signals are transmitted.

[0069] like Figure 8 As shown, based on any of the foregoing embodiments, the electronic device 10 may further include: a switching circuit 144 and at least one second antenna ANT2. The second antenna ANT2 is disposed within the housing 11, and in this embodiment, the second antenna ANT2 can serve as a built-in antenna of the electronic device 10. The second antenna ANT2 can be a single-frequency antenna, a multi-band antenna, a directional antenna, or an omnidirectional antenna. The second antenna ANT2 can support the radiation of at least one of 2G, 3G, 4G, and 5G signals. The number of second antennas ANT2 may be 1, 2, 3, 4, 6, 8, or 10 to meet the communication requirements of the communication device.

[0070] For example, multiple second antennas ANT2 are spaced apart along the periphery of the customer's front-end equipment, and the radiating surfaces of the multiple second antennas ANT2 face at least two different directions. This can also be understood as each second antenna ANT2 having a radiating surface, which can be understood as the plane on which the radiator of the second antenna ANT2 radiates the antenna signal. The radiating surfaces of the multiple second antennas ANT2 face at least two directions to achieve 360° omnidirectional coverage in the horizontal plane. Different radiating surfaces of the second antennas ANT2 have different beam scanning ranges. Multiple second antennas ANT2 can be placed at different locations on the customer's front-end equipment, ensuring that the radiating surfaces of the multiple second antennas ANT2 face at least two directions, so that the beam scanning range of each antenna can achieve 360° omnidirectional coverage in the horizontal plane.

[0071] The switching circuit 144 is connected to the processing circuit 142, the radio frequency circuit 143, the first coupling module 12, and each second antenna ANT2. Specifically, the first terminal of the switching circuit 144 is connected to the radio frequency circuit 143, and its multiple second terminals are respectively connected to the first coupling module 12 and each second antenna ANT2. The control terminal of the switching circuit 144 is connected to the processing circuit 142. The processing circuit 142 is also used to output a control signal to the switching circuit 144 based on the received capacitance information, so as to control the switching circuit 144 to select and conduct the radio frequency path between the target antenna and the radio frequency circuit 143, wherein the target antenna is one of the first antenna ANT1 and the second antenna ANT2.

[0072] The switching circuit 144 may include a multi-channel radio frequency switch, such as a single-pole multi-throw switch or a multi-pole multi-throw switch. The switching circuit 144 may also include multiple single-channel or multi-channel radio frequency switches. In this embodiment, the specific configuration of the switching circuit 144 is not limited; its configuration can be determined based on the number of target antennas and the total number of the first antenna ANT1 and the second antenna ANT2. For example, when there is one target antenna, the switching circuit 144 may include a single-pole multi-throw switch. When there are multiple target antennas, the switching circuit 144 may include a multi-pole multi-throw switch, or multiple single-pole multi-throw switches.

[0073] Specifically, when the first coupling module 12 and the second coupling module 13 are capacitively coupled, the capacitance value in the capacitance information received by the processing circuit 142 will change. Thus, the processing circuit 142 can control the switching circuit 144 to open the radio frequency path between the first antenna ANT1 and the radio frequency circuit 143, so as to use the first antenna ANT1 (external antenna) for communication. Conversely, if the capacitance value in the capacitance information received by the processing circuit 142 does not change, for example, if the capacitance value is zero, then the processing circuit 142 can control the switching circuit 144 to open the radio frequency path between either the second antenna ANT2 and the radio frequency circuit 143, so as to use the second antenna ANT2 (internal antenna) for communication.

[0074] In this embodiment, when the first coupling module 12 and the second coupling module 13 are capacitively coupled, the processing circuit 142 can use the first antenna ANT1 as the target antenna for communication, which can improve the communication performance of the electronic device 10.

Processing module 22 may include one or more microprocessors, microcontrollers, digital signal processors, baseband processors, power management units, audio codec chips, application-specific integrated circuits, etc. Processing module 22 can be configured to implement control algorithms for controlling the use of antennas in the customer front-end equipment.
