Description

Technical Field

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

[0002] Electronic devices (such as mobile phones and tablets) generally consist of a mid-frame, a display panel, and a back cover. The display panel covers one side of the mid-frame, and the back cover covers the other side. Both the mid-frame and the back cover have radiators, and electronic devices can achieve different communication functions through different radiators. However, the signal gain formed by the radiator on the back cover is relatively low, resulting in insufficient communication performance of the electronic device. Summary of the Invention

[0003] This invention provides an antenna structure and electronic device that can improve the signal gain formed by the radiator on the back cover, thereby improving communication performance.

[0004] In a first aspect, embodiments of this application provide an antenna structure, including: a radiating structure, a first connecting portion, and a second connecting portion. The radiating structure includes a first conductive layer and a second conductive layer, which are arranged parallel to each other and spaced apart. In a plane parallel to the first conductive layer, the projections of the first conductive layer and the second conductive layer at least partially overlap. The first connecting portion is disposed between the first conductive layer and the second conductive layer, and the first conductive layer and the second conductive layer are coupled through the first connecting portion. A first feed point is disposed on a portion of the first conductive layer on one side of the first connecting portion. The second connecting portion is disposed on the side of the second conductive layer away from the first conductive layer, and the second conductive layer is coupled to the second connecting portion. The second connecting portion is used to couple with the second feed point, which is grounded. The first feed point and the second feed point are configured to be fed in an antisymmetric feeding manner.

[0005] With the above configuration, the second conductive layer and the first conductive layer are coupled through the first connection portion. Therefore, during operation, while the first conductive layer is fed with radio frequency signals, the second conductive layer is coupled with radio frequency signals. The first and second conductive layers simultaneously radiate electromagnetic signals outward, which can improve the gain and bandwidth of the antenna structure.

[0006] In some embodiments that may include the above-described embodiments, the first conductive layer is annular, and there are multiple first connecting portions arranged at intervals around the center line of the first conductive layer. There are also multiple first feed points, with one first feed point located on the first conductive layer between two adjacent first connecting portions. This arrangement allows the antenna structure to form multiple antenna modes, thereby improving the communication performance of the antenna structure.

[0007] It is understood that multiple antenna modes can communicate on different frequency bands. In this case, the antenna structure can cover multiple communication frequency bands (such as Bluetooth band, WIFI band, GPS band, cellular band, etc.), thereby enriching the communication frequency bands of the antenna structure. Of course, multiple antenna modes can also cover the same communication frequency band, with each antenna mode having a different communication area to increase the signal coverage area. This application does not limit this.

[0008] In some embodiments that may include the above-described examples, the second conductive layer is annular, and the centerline of the second conductive layer is collinear with the centerline of the first conductive layer. This configuration increases the overlapping area of ​​the first and second conductive layers projected onto the insulating housing, allowing more radio frequency signals to couple to the second conductive layer, thereby further improving the gain of the antenna structure.

[0009] In some embodiments that may include the above-described embodiments, there are multiple second connecting portions, which are spaced apart around the center line of the second conductive layer. This arrangement can improve the uniformity of force on the second conductive layer.

[0010] Secondly, embodiments of this application also provide an antenna structure, including: a radiating structure, a first connecting portion, and a second connecting portion; the radiating structure includes a first conductive layer and a second conductive layer, the first conductive layer and the second conductive layer are arranged parallel to each other and spaced apart, and in a plane parallel to the first conductive layer, the projection of the first conductive layer and the projection of the second conductive layer at least partially overlap; the first connecting portion is disposed between the first conductive layer and the second conductive layer, and the first conductive layer and the second conductive layer are coupled through the first connecting portion; the second connecting portion is disposed on the side of the second conductive layer away from the first conductive layer, the second conductive layer is coupled to the second connecting portion, a first feed point is disposed on a portion of the second conductive layer on one side of the second connecting portion, the second connecting portion is used to couple with the second feed point, the second feed point is grounded, and the first feed point and the second feed point are configured to be fed in an antisymmetric feeding manner.

[0011] With the above configuration, the second conductive layer and the first conductive layer are coupled through the first connection portion. Therefore, during operation, while the second conductive layer is fed with radio frequency signals, the first conductive layer is coupled with radio frequency signals. The first and second conductive layers simultaneously radiate electromagnetic signals outward, which can improve the gain and bandwidth of the antenna structure.

[0012] In some embodiments that may include the above-described embodiments, the second conductive layer is annular, and there are multiple second connecting portions arranged at intervals around the center line of the second conductive layer. There are also multiple first feed points, with one first feed point located on the second conductive layer between two adjacent second connecting portions. This arrangement allows the antenna structure to form multiple antenna modes, thereby improving the communication performance of the antenna structure.

[0013] In some embodiments that may include the above-described examples, the first conductive layer is annular, and the centerline of the first conductive layer is collinear with the centerline of the second conductive layer. This configuration increases the overlapping area of ​​the first and second conductive layers projected onto the insulating shell, allowing more radio frequency signals to couple to the first conductive layer, thereby further improving the gain of the antenna structure.

[0014] In some embodiments that may include the above-described embodiments, there are multiple first connecting portions, which are spaced apart around the center line of the second conductive layer. This arrangement can improve the uniformity of force on the first conductive layer.

[0015] Thirdly, embodiments of this application also provide an electronic device, including: an insulating housing and an antenna structure as described above, wherein a portion of the insulating housing is disposed between a first conductive layer and a second conductive layer, and both the first conductive layer and the second conductive layer are attached to the insulating housing.

[0016] The electronic device provided in this application includes the antenna structure in any of the above embodiments, and therefore can achieve the same technical effect and solve the same technical problem.

[0017] In some embodiments that may include the above-described examples, the electronic device further includes a camera device. A mounting hole is provided on the insulating housing, and a first conductive layer surrounds the outer periphery of the mounting hole. The camera device is disposed in the mounting hole. The first conductive layer can serve as a decorative component of the camera device to enhance the decorative effect of the electronic device. On the other hand, since electronic devices generally require decorative components of the camera device to be mounted on the insulating housing, using the first conductive layer as a decorative component eliminates the need for an additional first conductive layer, thus simplifying the structure of the electronic device.

[0018] In some embodiments that may include the above examples, there are multiple first feed points, which are spaced apart. The electronic device also includes a radio frequency (RF) device and a switching device. The RF device is coupled to each first feed point through the switching device. The switching device has multiple operating states, and in different operating states, the switching device couples the RF device to different first feed points. With this configuration, the switching device can control the antenna structure to generate different antenna modes.

[0019] In some embodiments that may include the above embodiments, the switching device is configured to sequentially switch between different operating states, with a different communication area of ​​the antenna structure in each operating state. That is, the switching device sequentially couples different first feed points to the radio frequency device, and the antenna structure sequentially switches between different antenna modes. In each operating state, the communication area corresponding to the antenna structure is different, thereby enabling beam scanning of electromagnetic signals and increasing the signal coverage area.

[0020] For example, each antenna mode of the antenna structure can cover the same communication frequency band (such as Bluetooth band, WIFI band, GPS band, cellular band). The communication area corresponding to each antenna mode is different. By switching each working device in sequence, the antenna structure can switch different antenna modes in sequence, thereby scanning different areas in sequence and increasing the signal coverage area.

[0021] In some embodiments that may include the above examples, the antenna structure operates in different frequency bands under different operating states. This configuration allows the antenna structure to cover different communication frequency bands, thereby increasing the bandwidth of the antenna structure.

[0022] In some embodiments that may include the above-described examples, there are multiple first feed points, spaced apart. The electronic device further includes a radio frequency (RF) device and a phase-shifting device. The RF device is coupled to each first feed point via the phase-shifting device, which sequentially adjusts the phase of each first feed point to change the communication area of ​​the antenna structure. This configuration, by sequentially adjusting the phase of the RF signal fed to each first feed point via the phase-shifting device, causes the communication area of ​​the antenna structure to change sequentially, thereby achieving beam scanning of different areas and increasing the signal coverage area.

[0023] In some embodiments that may include the above-described embodiments, the electronic device further includes a ground plane, which is spaced apart from the insulating housing. The ground plane is located on the side of the second connection portion opposite to the second conductive layer, and the second connection portion is coupled to the ground plane. The second feed point is located on the ground plane. The ground plane can assist the antenna structure in transmitting signals outward.

[0024] In some embodiments that may include the above embodiments, the electronic device includes a motherboard, and the ground plane includes a ground layer disposed on the motherboard. In implementations where the electronic device includes a radio frequency (RF) device, the RF device is generally disposed on the motherboard, and the ground plane includes a ground layer disposed on the motherboard. This can reduce the distance between the second feed line located on the ground plane and the motherboard, thereby reducing the loss of RF signals during transmission.

[0025] Fourthly, embodiments of this application also provide an antenna structure, including: a radiating structure, a first connecting portion, and a second connecting portion. The radiating structure includes a first conductive layer and a second conductive layer, which are arranged parallel to each other and spaced apart. In a plane parallel to the first conductive layer, the projection of the first conductive layer and the projection of the second conductive layer at least partially overlap. The first connecting portion is disposed between the first conductive layer and the second conductive layer, and the first conductive layer and the second conductive layer are coupled through the first connecting portion. The second connecting portion is disposed on the side of the second conductive layer away from the first conductive layer, and the second conductive layer is coupled to the second connecting portion, which is grounded. A first slot is provided on the second conductive layer on one side of the second connecting portion, a first feed point is provided on the second conductive layer on one side of the first slot, and a second feed point is provided on the second conductive layer on the other side of the first slot. The first feed point and the second feed point are configured to be fed in an antisymmetric feeding manner.

[0026] With the above settings, the first feed point and the second feed point are configured to be fed in an anti-symmetric manner. During operation, while the second conductive layer is fed with radio frequency signals, the first conductive layer is coupled with radio frequency signals. The first and second conductive layers simultaneously radiate electromagnetic signals outward, which can improve the gain and bandwidth of the antenna structure.

[0027] In some embodiments that may include the above-described examples, the second conductive layer is annular, and there are multiple second connecting portions. These multiple second connecting portions are spaced apart around the center line of the second conductive layer. A first gap is provided on the second conductive layer between any two adjacent second connecting portions. A first feed point is provided on the second conductive layer on one side of each first gap, and a second feed point is provided on the second conductive layer on the other side of each first gap. This arrangement allows the antenna structure to form multiple antenna modes, thereby improving the communication performance of the antenna structure.

[0028] It is understood that multiple antenna modes can communicate on different frequency bands. In this case, the antenna structure can cover multiple communication frequency bands (such as Bluetooth band, WIFI band, GPS band, cellular band, etc.), thereby enriching the communication frequency bands of the antenna structure. Of course, multiple antenna modes can also cover the same communication frequency band, with each antenna mode having a different communication area to increase the signal coverage area. This application does not limit this.

[0029] In some embodiments that may include the above-described examples, the first conductive layer is annular, and the centerline of the first conductive layer is collinear with the centerline of the second conductive layer. This configuration increases the overlapping area of ​​the first and second conductive layers projected onto the insulating shell, allowing more radio frequency signals to couple to the first conductive layer, thereby further improving the gain of the antenna structure.

[0030] In some embodiments that may include the above-described embodiments, there are multiple first connecting portions, which are spaced apart around the center line of the second conductive layer. This arrangement can improve the uniformity of force on the first conductive layer.

[0031] Fifthly, embodiments of this application also provide an antenna structure, including: a radiating structure, a first connecting portion, and a second connecting portion. The radiating structure includes a first conductive layer and a second conductive layer, which are arranged parallel to each other and spaced apart. In a plane parallel to the first conductive layer, the projections of the first conductive layer and the second conductive layer at least partially overlap. The first connecting portion is disposed between the first conductive layer and the second conductive layer, and the first conductive layer and the second conductive layer are coupled through the first connecting portion. A first gap is provided on the first conductive layer on one side of the first connecting portion, a first feed point is provided on the first conductive layer on one side of the first gap, and a second feed point is provided on the first conductive layer on the other side of the first gap. The first feed point and the second feed point are configured to be fed in an antisymmetric feeding manner. The second connecting portion is disposed on the side of the second conductive layer away from the first conductive layer, and the second conductive layer is coupled to the second connecting portion, which is grounded.

[0032] In some embodiments that may include the above-described examples, the first conductive layer is annular, and there are multiple first connecting portions. These multiple first connecting portions are spaced apart around the center line of the first conductive layer. A first gap is provided on the first conductive layer between any two adjacent first connecting portions. A first feed point is provided on the first conductive layer on one side of each first gap, and a second feed point is provided on the first conductive layer on the other side of each first gap. This arrangement allows the antenna structure to form multiple antenna modes, thereby improving the communication performance of the antenna structure.

[0033] It is understood that multiple antenna modes can communicate on different frequency bands. In this case, the antenna structure can cover multiple communication frequency bands (such as Bluetooth band, WIFI band, GPS band, cellular band, etc.), thereby enriching the communication frequency bands of the antenna structure. Of course, multiple antenna modes can also cover the same communication frequency band, with each antenna mode having a different communication area to increase the signal coverage area. This application does not limit this.

[0034] In some embodiments that may include the above-described examples, the second conductive layer is annular, and the centerline of the first conductive layer is collinear with the centerline of the second conductive layer. This configuration increases the overlapping area of ​​the first and second conductive layers projected onto the insulating shell, allowing more radio frequency signals to couple to the first conductive layer, thereby further improving the gain of the antenna structure.

[0035] In some embodiments that may include the above-described embodiments, there are multiple second connecting portions, which are spaced apart around the center line of the second conductive layer. This arrangement can improve the uniformity of force on the second conductive layer.

[0036] In a sixth aspect, embodiments of this application also provide an antenna structure, including: a radiating structure and a first connecting portion. The radiating structure includes radiating stubs and a first conductive layer, the first conductive layer and the radiating stubs being spaced apart. The first conductive layer is disposed on an insulating housing of an electronic device, the radiating stubs are disposed on the inner side of the insulating housing, and in a plane parallel to the first conductive layer, the projection of the radiating stubs at least partially overlaps with the projection of the first conductive layer. The first connecting portion is disposed between the radiating stubs and the first conductive layer, the radiating stubs being coupled to the first conductive layer through the first connecting portion. A first slot is disposed on a radiating stub on one side of the first connecting portion, a first feed point is disposed on a radiating stub on one side of the first slot, and a second feed point is disposed on a radiating stub on the other side of the first slot. The first feed point and the second feed point are configured to be fed in an antisymmetric feeding manner.

[0037] With this configuration, the first and second feed points are fed in an antisymmetric manner. During operation, while the radiating stubs are fed with radio frequency signals, the first conductive layer is coupled with radio frequency signals, thereby simultaneously radiating electromagnetic signals outward, which can improve the gain and bandwidth of the antenna structure.

[0038] In some embodiments that may include the above embodiments, the radiating structure further includes a second conductive layer, the first conductive layer and the second conductive layer are arranged parallel and spaced apart, and in a plane parallel to the first conductive layer, the projection of the first conductive layer and the projection of the second conductive layer at least partially overlap; the second conductive layer is disposed between the first conductive layer and the radiating branch.

[0039] The electronic device also includes a second connection portion disposed between the first conductive layer and the second conductive layer. The first conductive layer and the second conductive layer are coupled through the second connection portion, and the first connection portion is coupled to both the second conductive layer and the radiating branch.

[0040] With this configuration, the radiating stub can couple signals to the first and second conductive layers, thereby enabling the first and second conductive layers and the radiating stub to radiate signals outward simultaneously, further improving the gain of the antenna structure.

[0041] In some embodiments that may include the above-described examples, the radiating stub is ring-shaped, and there are multiple first connecting portions. These multiple first connecting portions are spaced apart around the center line of the radiating stub. A first gap is provided on each radiating stub between two adjacent first connecting portions. A first feed point is provided on the radiating stub on one side of each first gap, and a second feed point is provided on the radiating stub on the other side of each first gap. This arrangement allows the antenna structure to form multiple antenna modes, thereby improving the communication performance of the antenna structure.

[0042] It is understood that multiple antenna modes can communicate on different frequency bands. In this case, the antenna structure can cover multiple communication frequency bands (such as Bluetooth band, WIFI band, GPS band, cellular band, etc.), thereby enriching the communication frequency bands of the antenna structure. Of course, multiple antenna modes can also cover the same communication frequency band, with each antenna mode having a different communication area to increase the signal coverage area. This application does not limit this.

[0043] In some embodiments that may include the above-described embodiments, both the first conductive layer and the second conductive layer are annular, the centerline of the first conductive layer is collinear with the centerline of the second conductive layer, and the centerline of the first conductive layer is collinear with the centerline of the radiating stub. This configuration increases the overlapping area of ​​the radiating stub and the conductive layer projected onto the insulating shell, further enabling the radiating stub to couple radio frequency signals to the first and second conductive layers, thereby further improving the gain of the antenna structure.

[0044] In some embodiments that may include the above-described embodiments, there are multiple second connecting portions, which are spaced apart around the center line of the second conductive layer. This arrangement can improve the uniformity of force distribution on the first conductive layer.

[0045] In a seventh aspect, embodiments of this application also provide an electronic device, including: an insulating housing and an antenna structure as described above, wherein a first conductive layer is attached to the insulating housing and a radiating branch is disposed on the inner side of the insulating housing.

[0046] The electronic device provided in this application includes the antenna structure in any of the above embodiments, and therefore can achieve the same technical effect and solve the same technical problem.

[0047] In some embodiments that may include the above-described examples, the electronic device further includes a camera device. A mounting hole is provided on the insulating housing, and a first conductive layer surrounds the outer periphery of the mounting hole. The camera device is disposed in the mounting hole. The first conductive layer can serve as a decorative component of the camera device to enhance the decorative effect of the electronic device. On the other hand, since electronic devices generally require decorative components of the camera device to be mounted on the insulating housing, using the first conductive layer as a decorative component eliminates the need for an additional first conductive layer, thus simplifying the structure of the electronic device.

[0048] In some embodiments that may include the above-described examples, there are multiple first slots spaced apart. Each first slot corresponds to a first feed point and a second feed point. The electronic device also includes a radio frequency (RF) device and a switching device. The RF device is coupled to each first feed point and each second feed point through the switching device. The switching device has multiple operating states, and in different operating states, the switching device couples the RF device to the first feed point and the second feed point corresponding to different first slots. With this configuration, the switching device can control the antenna structure to generate different antenna modes.

[0049] In some embodiments that may include the above embodiments, the switching device is configured to sequentially switch between different operating states, with a different communication area of ​​the antenna structure in each operating state. That is, the switching device sequentially couples the first feed point and the second feed point corresponding to different first gaps with the radio frequency device, and the antenna structure sequentially switches between different antenna modes. In each operating state, the communication area corresponding to the radiating structure is different, thereby enabling beam scanning of electromagnetic signals and increasing the signal coverage area.

[0050] For example, the antenna modes of the antenna structure can cover the same communication frequency band (such as Bluetooth band, WIFI band, GPS band, cellular band). The communication area corresponding to the radiating structure is different in each antenna mode. By switching the working devices in sequence, the antenna structure can switch different antenna modes in sequence, thereby scanning different areas in sequence and increasing the signal coverage area.

[0051] In some embodiments that may include the above examples, the antenna structure operates in different frequency bands under different operating states. This configuration allows the antenna structure to cover different communication frequency bands, thereby increasing the bandwidth of the antenna structure.

[0052] In some embodiments that may include the above-described examples, there are multiple first slots spaced apart. Each first slot is provided with a first feed point and a second feed point. The electronic device also includes a radio frequency (RF) device and a phase-shifting device. The RF device is coupled to each first feed point and each second feed point through the phase-shifting device. The phase-shifting device is used to adjust the phase of each first feed point and each second feed point to change the communication area of ​​the antenna structure. With this configuration, the phase of the RF signal fed into each first feed point is adjusted sequentially by the phase-shifting device, causing the communication area of ​​the radiating structure to change sequentially, thereby achieving beam scanning of different areas and increasing the signal coverage area.

[0053] In some embodiments that may include the above-described examples, the electronic device further includes a floor, which is spaced apart from the insulating housing, and radiating branches are disposed on the same layer as the floor. The floor can assist the antenna structure in transmitting signals outward.

[0054] The electronic device includes a motherboard, and the ground plane includes a grounding layer disposed on the motherboard. In implementations where the electronic device includes a radio frequency (RF) device, the RF device is generally disposed on the motherboard, and the ground plane includes a grounding layer disposed on the motherboard. This reduces the distance between the second feed line located on the ground plane and the motherboard, thereby reducing the loss of RF signals during transmission. Attached Figure Description

Detailed Implementation

[0082] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0083] The following explains the terminology that may appear in the embodiments of this application.

[0084] The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0085] In the embodiments of this application, directional terms such as "up," "down," "left," "right," "horizontal," and "vertical" are defined relative to the positions of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0086] Connection / Link: should be interpreted broadly. For example, "connection" can be a fixed connection, an electrical connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0087] Coupling can be understood as direct coupling and / or indirect coupling. "Coupled connection" can be understood as a direct coupling connection and / or indirect coupling connection. Direct coupling can also be called "electrical connection," which can be understood as physical contact and electrical conduction between components; it can also be understood as the form of connection between different components in a circuit structure through physical lines that can transmit electrical signals, such as copper foil or wires on a printed circuit board (PCB). "Indirect coupling" can be understood as electrical conduction between two conductors through a gap / non-contact method. In one embodiment, indirect coupling can also be called capacitive coupling, for example, signal transmission is achieved by forming an equivalent capacitance through coupling between the gaps between two conductive parts.

[0088] A radiator, or antenna stub, or radiating stub, is a device in an antenna used to receive / transmit electromagnetic wave radiation. In some cases, the term "antenna" is narrowly interpreted as a radiator, which converts guided wave energy from a transmitter into radio waves, or converts radio waves into guided wave energy, for radiating and receiving radio waves. The modulated high-frequency current energy (or guided wave energy) generated by the transmitter is transmitted to the transmitting radiator via a feed line, where it is converted into electromagnetic wave energy of a certain polarization and radiated in the desired direction. The receiving radiator converts electromagnetic wave energy of a certain polarization from a specific direction in space back into modulated high-frequency current energy, which is then delivered to the receiver input via a feed line. The radiator (or antenna stub, or radiating stub) may include conductors with specific shapes and sizes, such as wires or sheets; this application does not limit the specific shape.

[0089] Ground / Plug, broadly speaking, refers to at least a portion of any grounding layer, ground plane, or grounding metal layer within an electronic device (such as a mobile phone), or at least a portion of any combination of the aforementioned grounding layers, ground planes, or grounding components. "Ground / Plug" can be used for grounding components within an electronic device. In one embodiment, "Ground / Plug" may include any one or more of the following: a grounding layer of a circuit board of an electronic device, a ground plane formed within the frame of the electronic device, a grounding metal layer formed by a thin metal film beneath the screen, a conductive grounding layer of a battery, and conductive or metallic components electrically connected to the aforementioned grounding layer / ground plane / metal layer. In one embodiment, the circuit board may be a PCB, such as an 8-layer, 10-layer, or 12-14-layer board having 8, 10, 12, 13, or 14 layers of conductive material, or components separated and electrically insulated by dielectric or insulating layers such as fiberglass or polymers. In one embodiment, the circuit board includes a dielectric substrate, a grounding layer, and a trace layer, the trace layer and the grounding layer being electrically connected through vias. In one embodiment, components such as displays, touch screens, input buttons, transmitters, processors, memory, batteries, charging circuits, and system-on-chip (SoC) architectures may be mounted on or connected to a circuit board; or electrically connected to trace layers and / or ground layers in the circuit board.

[0090] Grounding: refers to coupling with the aforementioned ground / floor in any way. In one embodiment, grounding can be achieved through physical grounding, such as through a structural component of the mid-frame to achieve a physical ground at a specific location on the frame (or, physical ground). In another embodiment, grounding can be achieved through device grounding, such as through devices like capacitors / inductors / resistors connected in series or parallel (or, device ground).

[0091] Resonant frequency: The resonant frequency is also called the resonance frequency. The resonant frequency can have a frequency range, that is, the frequency range in which resonance occurs. The resonant frequency can be a frequency range where the return loss characteristic is less than -6dB. The frequency corresponding to the strongest resonance is the center frequency. The return loss characteristic of the center frequency can be less than -20dB.

[0092] Resonant frequency band: The range of resonant frequencies is the resonant frequency band. The return loss characteristics at any frequency point within the resonant frequency band can be less than -6dB or -5dB.

[0093] Communication / Operating Frequency Band: Regardless of the type of antenna, it always operates within a certain frequency range (bandwidth). For example, an antenna supporting the B40 band operates within the frequency range of 2300MHz to 2400MHz, or in other words, its operating frequency band includes the B40 band. The frequency range that meets the specifications can be considered the antenna's operating frequency band. The width of the operating frequency band is called the operating bandwidth. The operating bandwidth of an omnidirectional antenna may reach 3-5% of the center frequency. The operating bandwidth of a directional antenna may reach 5-10% of the center frequency. Bandwidth can be considered as a frequency range on both sides of the center frequency (e.g., the resonant frequency of a dipole), where the antenna characteristics are within the acceptable range of the center frequency.

[0094] The resonant frequency band and the operating frequency band can be the same or can partially overlap. In one embodiment, one or more resonant frequency bands of the antenna can cover one or more operating frequency bands of the antenna.

[0095] End / Point: The term "end / point" in the context of the antenna radiator's first end / second end / feed end / ground end / feed point / ground point / connection point should not be narrowly interpreted as necessarily an endpoint or end physically disconnected from other radiators. It can also be considered a point or segment on a continuous radiator. In one embodiment, "end / point" can include a connection / coupling region on the antenna radiator that couples to other conductive structures. For example, a feed end / feed point can be a coupling region on the antenna radiator that couples to a feed structure or feed circuit (e.g., a region facing a part of the feed circuit). Similarly, a ground end / ground point can be a connection / coupling region on the antenna radiator that couples to a ground structure or ground circuit.

[0096] The terms collinearity, coaxiality, coplanarity, symmetry (e.g., axial symmetry, or central symmetry), parallelism, perpendicularity, and similarity (e.g., same length, same width, etc.) mentioned in the embodiments of this application are all relative to the current technological level, and not absolute and strict mathematical definitions. There may be a deviation of less than a predetermined threshold (e.g., 1 mm, 0.5 mm, or 0.1 mm) between the edges of two collinear radiating stubs or two antenna elements in the line width direction. There may be a deviation of less than a predetermined threshold between the edges of two coplanar radiating stubs or two antenna elements in the direction perpendicular to their coplanar plane. There may be a deviation of a predetermined angle between two parallel or perpendicular antenna elements. In one embodiment, the predetermined threshold may be less than or equal to a threshold of 1 mm, for example, the predetermined threshold may be 0.5 mm or 0.1 mm. In one embodiment, the predetermined angle may be an angle within the range of ±10°, for example, the predetermined angle deviation is ±5°.

[0097] Antenna gain: Characterizes the degree to which an antenna concentrates the radiated input power. Generally, the narrower the main lobe and the smaller the side lobes of the antenna pattern, the higher the antenna gain.

[0098] dBi: Usually mentioned together with dBd. dBi and dBd are units of power gain, both relative values, but with different reference points. The reference point for dBi is an omnidirectional antenna; the reference point for dBd is a dipole. Generally, dBi and dBd are considered to represent the same gain, but the value expressed in dBi is 2.15 dBi larger than that expressed in dBd. For example, for an antenna with a gain of 16 dBd, its gain converted to dBi is 18.15 dBi, generally ignoring the decimal places, hence 18 dBi.

[0099] This application provides an electronic device, which may include devices such as mobile phones and tablets; the electronic device includes an antenna structure, which enables wireless communication between the electronic device and communication base stations, other electronic devices, satellites, etc.

[0100] Please refer to Figure 1 In the implementation of an electronic device including a mobile phone, the mobile phone includes a mid-frame 10, a display panel 20, and an insulating shell 30. The mid-frame 10 encloses an accommodating space 103. The display panel 20 covers one side of the mid-frame 10, and the insulating shell 30 covers the other side of the mid-frame 10. The accommodating space 103 can be sealed by the display panel 20 and the insulating shell 30. The electronic device also includes a motherboard 40 and a battery (not shown). The mid-frame 10 includes a frame 102 and a middle plate 101. The frame 102 encloses the accommodating space 103. The middle plate 101 is disposed within the accommodating space 103 and is connected to the frame 102. The motherboard 40 and the battery are both disposed within the accommodating space 103. The motherboard 40 is electrically connected to the display panel 20 to control the display panel 20 to display images. The battery is disposed on the middle plate 101 and is electrically connected to the motherboard 40 to supply power to the motherboard 40. The battery is located between the insulating shell 30 and the middle plate 101, that is, the insulating shell 30 covers the battery. For example, the insulating shell 30 can be a battery cover (or a back cover).

[0101] For example, the material of the insulating shell 30 may include insulating materials such as resin and ceramics, and the embodiments of this application do not limit this.

[0102] In the above implementation, the frame 102 can be provided with several radiators to form different antennas and realize different communication functions. It is understood that the material of the frame 102 is generally metal. Accordingly, part of the frame 102 can be used as a radiator to simplify the structure of the electronic device. In this embodiment, the antenna structure is set on the insulating housing 30. The antenna structure does not occupy the space of the frame 102, so that the electronic device can have more antennas and enrich the communication functions of the electronic device.

[0103] Please refer to Figure 2 In this embodiment, the antenna structure includes a radiating structure 510, which includes a first conductive layer 511 and a second conductive layer 512. The first conductive layer 511 and the second conductive layer 512 are arranged parallel to each other and spaced apart. Both the first conductive layer 511 and the second conductive layer 512 are attached to the insulating housing 30. The first conductive layer 511 is located on the outer surface of the insulating housing 30, and the second conductive layer 512 is located on the inner surface of the insulating housing 30. The outer surface is the exposed surface of the insulating housing 30, and the inner surface is the surface of the insulating housing 30 facing the accommodating space 103 (e.g., ...). Figure 1 The inner and outer surfaces of the surface (as shown) are arranged opposite each other.

[0104] For example, the materials of the first conductive layer 511 and the second conductive layer 512 may include metal layers such as copper, silver, aluminum, and steel; the first conductive layer 511 and the second conductive layer 512 may be continuous metal layers, or the first conductive layer 511 and the second conductive layer 512 may be in the form of a grid or lines (such as silver nanowires), and the embodiments of this application do not limit this.

[0105] Please refer to Figure 3 and Figure 4In some implementations, the electronic device also includes a camera device 60. The insulating housing 30 has a mounting hole 301, and the camera device 60 is disposed within the mounting hole 301. It is understood that part of the camera device 60 is disposed within the mounting hole 301, while the remaining part is disposed within an accommodating space. The camera device 60 can be mounted on the motherboard and electrically connected to the motherboard to control the camera device 60 to acquire external images. For example, a first conductive layer 511 can surround the outer periphery of the mounting hole 301. Correspondingly, the first conductive layer 511 can serve as a decorative component of the camera device 60 to enhance the decorative effect of the electronic device. On the other hand, since electronic devices generally require decorative components of the camera device 60 to be disposed on the insulating housing 30, using the first conductive layer 511 as a decorative component means that the decorative component of the electronic device can be used as the first conductive layer 511, eliminating the need for an additional first conductive layer 511 and simplifying the structure of the electronic device. Of course, this application embodiment does not limit this, and the first conductive layer 511 can also be disposed in other positions of the insulating housing 30.

[0106] Please refer to Figure 5 In this embodiment of the application, the antenna structure 50 further includes a first connecting portion 520 and a second connecting portion 530. The first connecting portion 520 is disposed between the first conductive layer 511 and the second conductive layer 512, and the first conductive layer 511 and the second conductive layer 512 are coupled through the first connecting portion 520. It can be understood that the first connecting portion 520 can pass through the insulating shell 30, and one end of the first connecting portion 520 is connected to the first conductive layer 511, and the other end of the first connecting portion 520 is connected to the second conductive layer 512. In this way, the first conductive layer 511 and the second conductive layer 512 can be fixed on the insulating shell 30 through the first connecting portion 520.

[0107] For example, the first connecting portion 520 may include a bolt. Correspondingly, the first conductive layer 511 is provided with a threaded hole, and the second conductive layer 512 is provided with a through hole. After the bolt passes through the through hole, it engages with the threaded hole to achieve coupling between the first conductive layer 511 and the second conductive layer 512, while simultaneously fixing the first conductive layer 511 and the second conductive layer 512 together. Alternatively, the first connecting portion 520, the first conductive layer 511, and the second conductive layer 512 may be an integral structure, and the insulating shell 30 may be formed between the first conductive layer 511 and the second conductive layer 512 by injection molding.

[0108] The second connection portion 530 is disposed on the side of the second conductive layer 512 facing away from the first conductive layer 511, and the second connection portion 530 is located in the accommodating space 103 (e.g., ...). Figure 1 As shown, the second connecting portion 530 is coupled to the second conductive layer 512.

[0109] Please refer to Figure 6 and Figure 7 In some embodiments, a first feed point 540 is provided on the first conductive layer 511 on one side of the first connection portion 520, that is, along a direction parallel to the first conductive layer 511, a first feed point 540 is provided on the first conductive layer 511 on one side of the first connection portion 520. The second connection portion 530 is coupled to the second feed point 550, and the second feed point 550 is grounded. It is understood that the electronic device may include a ground plane 401, the second feed point 550 may be disposed on the ground plane 401, and correspondingly, the second connection portion 530 may be coupled to the ground plane 401. The ground plane 401 can assist the antenna structure in transmitting signals outward. For example, the ground plane 401 may include a middle plate 101 (such as...). Figure 1 (as shown), at least one of the following: the grounding layer in the motherboard 40, the grounding metal layer in the display panel 20, and the conductive grounding layer of the battery.

[0110] In some examples, the second connecting portion 530 may include a metal column, a metal bracket, or an elastic metal sheet, etc. One end of the second connecting portion 530 is connected to the second conductive layer 512, and the other end of the second connecting portion 530 is connected to the floor 401. A dielectric layer or air may be present between the floor 401 and the second conductive layer 512, wherein the material of the dielectric layer may include resin, rubber, etc., and this embodiment does not limit this. In the implementation where the first conductive layer 511 serves as a decorative component of the camera device, the first connecting portion 520 is connected to the first conductive layer 511, and the second connecting portion 530 can be used to fix the second conductive layer 512 and the first conductive layer 511.

[0111] In the above implementation, the first feed point 540 and the second feed point 550 are configured to be anti-symmetrically fed. That is, the radio frequency signals fed into the first feed point 540 and the second feed point 550 are both sinusoidal signals. The signals fed into the first feed point 540 and the second feed point 550 have the same frequency, the same amplitude, and a phase difference of 180°. During operation, the current path is as follows... Figure 7 As shown by the dotted lines, the portion of the first conductive layer 511 between the first feed point 540 and the first connection portion 520, the second conductive layer 512 between the first connection portion 520 and the second connection portion 530, and the second connection portion 530 constitute an antenna stub to generate resonance and radiate electromagnetic signals outward, thereby forming an antenna mode.

[0112] It is understandable that by appropriately setting the distance between the first connecting part 520 and the first feed point 540, the resonant frequency of the formed antenna pattern can be adjusted, thereby adjusting the communication frequency band covered by the antenna pattern. For example, appropriately reducing the distance between the first connecting part 520 and the first feed point 540 can increase the resonant frequency of the antenna pattern.

[0113] In this embodiment, in a plane parallel to the first conductive layer 511, the projection of the first conductive layer 511 at least partially overlaps with the projection of the second conductive layer 512. That is, in the insulating shell 30 (e.g., Figure 6 As shown, the projection of the first conductive layer 511 at least partially overlaps with the projection of the second conductive layer 512; and the second conductive layer 512 and the first conductive layer 511 are coupled through the first connection portion 520. Therefore, during operation, while the first conductive layer 511 is fed with radio frequency signals, the second conductive layer 512 is coupled with radio frequency signals. The first conductive layer 511 and the second conductive layer 512 simultaneously radiate electromagnetic signals outward, which can improve the gain and bandwidth of the antenna structure 50.

[0114] Continue to refer to Figure 6 and Figure 7 In some examples, the first conductive layer 511 is annular, and its centerline is perpendicular to the insulating shell 30. Multiple first connecting portions 520 are arranged at intervals around the centerline of the first conductive layer 511; correspondingly, multiple first feed points 540 are provided, with one first feed point 540 between the first conductive layers 511 of two adjacent first connecting portions 520. Each first feed point 540 and each second feed point 550 can form an antenna pattern. This arrangement allows the antenna structure 50 to form multiple antenna patterns, thereby improving the communication performance of the antenna structure 50.

[0115] It is understood that the communication frequency bands of multiple antenna modes can be different. In this case, the antenna structure 50 can cover multiple communication frequency bands (such as Bluetooth band, WIFI band, GPS band, cellular band, etc.), thereby enriching the communication frequency bands of the antenna structure 50. Of course, multiple antenna modes can also cover the same communication frequency band, with each antenna mode having a different communication area to increase the signal coverage area. This application embodiment does not impose any limitations on this.

[0116] Continue to refer to Figure 7 In the above implementation, a second feed point 550 can be provided on the floor 401, that is, each first feed point 540 and second feed point 550 forms an antenna pattern; of course, multiple second feed points 550 can also be provided on the floor 401, and each first feed point 540 and a second feed point 550 form an antenna pattern.

[0117] The first conductive layer 511 serves as the imaging device 60 (e.g. Figure 3 In the implementation of the decorative component shown, the center line of the first conductive layer 511 is collinear with the center line of the mounting hole 301. That is to say, the first conductive layer 511 surrounds the outer periphery of the camera device 60, which can further improve the decorative effect.

[0118] Continue to refer to Figure 7 In some examples, the second conductive layer 512 may also be annular, with the center line of the second conductive layer 512 collinear with the center line of the first conductive layer 511. This arrangement can increase the overlapping area of ​​the projection of the first conductive layer 511 and the second conductive layer 512 on the insulating housing 30, allowing more radio frequency signals to be coupled to the second conductive layer 512, thereby further improving the gain of the antenna structure 50.

[0119] In a ring-shaped implementation of the second conductive layer 512, there can be multiple second connecting portions 530, which can be spaced apart around the center line of the second conductive layer 512. This arrangement can improve the uniformity of force on the second conductive layer 512.

[0120] Continue to refer to Figure 7 In some examples, there can be two first connection portions 520 and two second connection portions 530, and correspondingly, there can be two first feed points 540 and two second feed points 550, so that the antenna structure 50 can generate two antenna modes; the projections of the first connection portions 520 and the second connection portions 530 on the insulating housing 30 can at least partially overlap, or the projections of the first connection portions 520 and the second connection portions 530 on the insulating housing 30 can be spaced apart.

[0121] Please refer to Figure 8 In some examples, there can be four first connection portions 520 and four second connection portions 530, and correspondingly, there can be four first feed points 540 and four second feed points 550, so that the antenna structure 50 can generate four antenna modes; the projections of the first connection portions 520 and the second connection portions 530 on the insulating housing 30 can at least partially overlap, or the projections of the first connection portions 520 and the second connection portions 530 on the insulating housing 30 can be spaced apart.

[0122] Figures 9-12 They are respectively Figure 7 The radiation patterns of each antenna mode in the antenna structure 50 shown are derived from... Figures 9-12 It can be seen that under different antenna modes, the main lobe direction of the radiation pattern of antenna structure 50 is different, that is, the communication area is different.

[0123] It is understood that the number of the first connecting parts 520 is not limited in this application embodiment, and the number of the first connecting parts 520 can be set according to the number of antenna modes of the antenna structure 50. The number of the second connecting parts 530 is not limited in this application embodiment, and the number of the second connecting parts 530 can be the same as the number of the first connecting parts 520. Of course, the number of the second connecting parts 530 can also be different from the number of the first connecting parts 520.

[0124] This application embodiment does not limit the shape of the first conductive layer 511, and the first conductive layer 511 can also be rectangular (e.g., ...). Figure 13 As shown), triangle (as shown) Figure 14 Given regular shapes such as ), the mounting area 517 enclosed by the first conductive layer 511 can be directly aligned with the mounting hole 301. Figure 3 As shown), the first conductive layer 511 can serve as a decorative component of the imaging device 60. Of course, the shape of the first conductive layer 511 can also be other irregular shapes, for example, such as... Figure 15 As shown, the first conductive layer 511 includes a conductive ring 513 and conductive wires 514. The conductive wires 514 are arranged along the diameter of the conductive ring 513, and both ends of the conductive wires 514 are connected to the conductive ring 513. The conductive wires 514 and the conductive ring 513 form two mounting areas 517. Correspondingly, mounting holes 301 (such as...) Figure 3 (As shown) can be directly opposite one or both people in the two installation areas 517; or, as Figure 16 As shown, the first conductive layer 511 includes a first conductive ring 515 and a second conductive ring 516. The center line of the first conductive ring 515 is collinear with the center line of the second conductive ring 516, and the inner diameter of the first conductive ring 515 is larger than the outer diameter of the second conductive ring 516. One or more conductive wires 514 are disposed between the first conductive ring 515 and the second conductive ring 516, and each conductive wire 514 is connected to the first conductive ring 515 and the second conductive ring 516. The mounting area 517 enclosed by the second conductive ring 516 can be directly aligned with the mounting hole 301 (e.g., ...). Figure 3 (As shown in the image) settings.

[0125] It is understood that the second conductive layer 512 and the first conductive layer 511 may have the same or different shapes, and the embodiments of this application do not impose any restrictions on this.

[0126] Unlike the embodiments described above, in other embodiments, such as Figure 17 and Figure 18 As shown, a first feed point 540 is disposed on the second conductive layer 512. The first feed point 540 is located on the second conductive layer 512 on one side of the second connection portion 530, that is, along a direction parallel to the second conductive layer 512, the first feed point 540 is located on one side of the second connection portion 530; the second connection portion 530 is also coupled to the second feed point 550, which is grounded. It is understood that the electronic device may include a ground plane 401, the second feed point 550 may be disposed on the ground plane 401, and correspondingly, the second connection portion 530 may be coupled to the ground plane 401. For example, the ground plane 401 may include a middle plate 101 (such as...). Figure 1 (as shown), at least one of the following: the grounding layer in the motherboard 40, the grounding metal layer in the display panel 20, and the conductive grounding layer of the battery.

[0127] In the above implementation, the first feed point 540 and the second feed point 550 are configured to be anti-symmetrically fed. That is, the radio frequency signals fed into the first feed point 540 and the second feed point 550 are both sinusoidal signals. The signals fed into the first feed point 540 and the second feed point 550 have the same frequency, the same amplitude, and a phase difference of 180°. During operation, the current path is as follows... Figure 18 As shown by the dotted line, the portion of the second conductive layer 512 and the second connecting portion 530 between the first feed point 540 and the second connecting portion 530 constitutes an antenna stub to generate resonance and radiate electromagnetic signals outward, thereby forming an antenna mode.

[0128] It is understandable that by appropriately setting the distance between the second connecting part 530 and the first feed point 540, the resonant frequency of the formed antenna pattern can be adjusted, thereby adjusting the communication frequency band covered by the antenna pattern. For example, appropriately reducing the distance between the second connecting part 530 and the first feed point 540 can increase the resonant frequency of the antenna pattern to cover a higher frequency communication band.

[0129] In this embodiment, in a plane parallel to the first conductive layer 511, the projection of the first conductive layer 511 at least partially overlaps with the projection of the second conductive layer 512. That is, on the insulating housing 30, the projection of the first conductive layer 511 at least partially overlaps with the projection of the second conductive layer 512. Furthermore, the second conductive layer 512 and the first conductive layer 511 are coupled through the first connection portion 520. Therefore, during operation, while the second conductive layer 512 is fed with radio frequency signals, the first conductive layer 511 is coupled with radio frequency signals. The first conductive layer 511 and the second conductive layer 512 simultaneously radiate electromagnetic signals outward, which can improve the gain and bandwidth of the antenna structure 50.

[0130] In some examples, the second conductive layer 512 is annular, and its centerline is perpendicular to the insulating housing 30. Multiple second connecting portions 530 are arranged at intervals around the centerline of the second conductive layer 512. Correspondingly, multiple first feed points 540 are provided, with one first feed point 540 on each side of the second conductive layer 512 between any two adjacent second connecting portions 530. Each first feed point 540 and each second feed point 550 can form an antenna pattern. This arrangement allows the antenna structure 50 to form multiple antenna patterns, thereby improving the communication performance of the antenna structure 50.

[0131] It is understood that the communication frequency bands of multiple antenna modes can be different. In this case, the antenna structure 50 can cover multiple communication frequency bands (such as Bluetooth band, WIFI band, GPS band, cellular band, etc.), thereby enriching the communication frequency bands of the antenna structure 50. Of course, multiple antenna modes can also cover the same communication frequency band, with each antenna mode having a different communication area to increase the signal coverage area. This application embodiment does not impose any limitations on this.

[0132] In the above implementation, a second feed point 550 can be provided on the floor 401, that is, each first feed point 540 and second feed point 550 forms an antenna pattern; of course, multiple second feed points 550 can also be provided on the floor 401, and each first feed point 540 and a second feed point 550 form an antenna pattern.

[0133] Continue to refer to Figure 18 In some examples, the first conductive layer 511 may also be annular, with the center line of the first conductive layer 511 collinear with the center line of the second conductive layer 512. This arrangement can increase the overlap between the first conductive layer 511 and the second conductive layer 512 within the insulating housing 30 (e.g., ...). Figure 17 The projected overlapping area on the antenna structure 50 (as shown in the figure) allows more radio frequency signals to be coupled to the first conductive layer 511, thereby further improving the gain of the antenna structure 50.

[0134] In a ring-shaped implementation of the first conductive layer 511, there can be multiple first connecting portions 520, which can be spaced apart around the center line of the first conductive layer 511. This arrangement can improve the uniformity of force on the first conductive layer 511.

[0135] The first conductive layer 511 serves as the imaging device 60 (e.g. Figure 3 In the implementation of the decorative component shown, the center line of the first conductive layer 511 is collinear with the center line of the mounting hole 301. That is to say, the first conductive layer 511 surrounds the outer periphery of the camera device 60, which can further improve the decorative effect.

[0136] Continue to refer to Figure 18 In some examples, there can be two first connection portions 520 and two second connection portions 530, and correspondingly, there can be two first feed points 540 and two second feed points 550, so that the antenna structure 50 can generate two antenna modes; the projections of the first connection portions 520 and the second connection portions 530 on the insulating housing 30 can at least partially overlap, or the projections of the first connection portions 520 and the second connection portions 530 on the insulating housing 30 can be spaced apart.

[0137] like Figure 19As shown, in some examples, there can be four first connection portions 520 and four second connection portions 530, and correspondingly, there can be four first feed points 540 and four second feed points 550, so that the antenna structure 50 can generate four antenna modes; the projections of the first connection portions 520 and the second connection portions 530 on the insulating housing 30 can at least partially overlap, or the projections of the first connection portions 520 and the second connection portions 530 on the insulating housing 30 can be spaced apart.

[0138] It is understood that the number of the first connecting parts 520 is not limited in this application embodiment, and the number of the first connecting parts 520 can be set according to the number of antenna modes of the antenna structure 50. The number of the second connecting parts 530 is not limited in this application embodiment, and the number of the second connecting parts 530 can be the same as the number of the first connecting parts 520. Of course, the number of the second connecting parts 530 can also be different from the number of the first connecting parts 520.

[0139] Please refer to Figure 20 In the above embodiments, the electronic device may further include a radio frequency (RF) device 70 and a switching device 80. The RF device 70 is coupled to each of the first feed points 540 through the switching device 80. The switching device 80 has multiple operating states, and in different operating states, the switching device 80 couples the RF device 70 to different first feed points 540. With this configuration, the switching device 80 can control the antenna structure 50 to generate different antenna modes.

[0140] It is understandable that in the implementation method of setting a second power supply point 550 on the floor 401 (such as...) Figure 7 and Figure 18 As shown), the radio frequency device 70 is coupled to each of the first feed points 540 and the second feed points 550 via the switching device 80. In a certain operating state, the switching device 80 couples the radio frequency device 70 to one first feed point 540 and one second feed point 550 to form a corresponding antenna mode. In different operating states, the switching device 80 couples the radio frequency device 70 to the second feed point 550 and different first feed points 540 to form a corresponding antenna mode. In the implementation where multiple second feed points 550 are set on the floor 401 (e.g....), Figure 8 and Figure 19 As shown, under different operating conditions, the switching device 80 couples the radio frequency device 70 with different first feed points 540 and corresponding second feed points 550 to form different antenna modes.

[0141] For example, the radio frequency device 70 may include a radio frequency chip that generates a radio frequency signal after receiving a baseband signal. The radio frequency chip can filter and / or amplify the radio frequency signal and then feed the radio frequency signal into the switching device 80. The switching device 80 feeds the radio frequency signal into the corresponding first feed point 540 and second feed point 550.

[0142] In some examples, the switching device 80 is configured to switch between different operating states in sequence, that is, the switching device 80 sequentially couples different first feed points 540 with the radio frequency device 70, and the antenna structure 50 sequentially switches between different antenna modes. In each operating state, the communication area corresponding to the antenna structure is different, thereby realizing beam scanning of electromagnetic signals and increasing the signal coverage area.

[0143] For example, the antenna modes of antenna structure 50 can cover the same communication frequency band (such as Bluetooth band, WIFI band, GPS band, cellular band). Each antenna mode corresponds to a different communication area. By sequentially switching the operating devices using switching device 80, antenna structure 50 can sequentially switch between different antenna modes, thereby scanning different areas and increasing the signal coverage area. For example,... Figures 9-12 As shown, in the implementation with four first feed points 540, the main lobe directions of the antenna modes corresponding to adjacent first feed points 540 differ by approximately 90°. When the antenna structure 50 sequentially switches between antenna modes, the main lobe directions of the antenna structure 50 are 45°, 135°, 225°, and 315° respectively, to achieve beam scanning. It is understandable that the main board direction can be reasonably set according to communication requirements. For example, in other examples, when the antenna structure 50 sequentially switches between antenna modes, the main lobe directions of the antenna structure 50 can be 0°, 90°, 180°, and 270° respectively.

[0144] In some examples, the communication frequency band corresponding to the antenna structure 50 is different under different operating states of the switching device 80. This setting allows the antenna structure 50 to cover different communication frequency bands, thereby enriching the communication frequency bands of the antenna structure 50.

[0145] Please refer to Figure 21In other examples, the electronic device includes a radio frequency (RF) device 70 and a phase shifter 90. The RF device 70 is coupled to each first feed point 540 via the phase shifter 90. The phase shifter 90 is used to sequentially adjust the phase of each first feed point 540. Since each first feed point 540 has a different phase, the communication area of ​​the antenna pattern corresponding to each first feed point 540 is different, thereby changing the communication area corresponding to the antenna structure 50. With this configuration, by sequentially adjusting the phase of the RF signal fed into each first feed point 540 via the phase shifter 90, the communication area of ​​the antenna structure 50 changes sequentially, thereby achieving beam scanning of different areas and increasing the signal coverage area.

[0146] For example, the phase shifting device 90 may include multiple phase shifters, each of which may include an output port. The output port of each phase shifter outputs a radio frequency signal with a different phase. The output port of each phase shifter is coupled to a first feed point 540. The multiple phase shifters sequentially transmit radio frequency signals, thereby enabling the antenna structure 50 to generate different antenna modes to cover different communication areas.

[0147] In the implementation of the electronic device including the radio frequency device 70, the radio frequency device is generally disposed on the motherboard, and the ground plane 401 includes a grounding layer disposed on the motherboard, which can reduce the distance between the second feed line located on the ground plane and the motherboard, thereby reducing the loss of radio frequency signals during transmission.

[0148] Unlike the embodiments described above, in some embodiments, please refer to... Figure 22 and Figure 23 A first slot 560 is provided on the second conductive layer 512 on one side of the second connection portion 530. A first feed point 540 is provided on the second conductive layer 512 on one side of the first slot 560, and a second feed point 550 is provided on the second conductive layer 512 on the other side of the first slot 560. The first feed point 540 can be located close to the first slot 560. For example, the distance between the first feed point 540 and the first slot 560 can be 0.1λ-0.5λ (such as 0.1λ, 0.2λ, 0.5λ, etc.). Similarly, the second feed point 550 is located close to the second slot. For example, the distance between the second feed point 550 and the first slot 560 can be 0.1λ-0.5λ (such as 0.1λ, 0.2λ, 0.5λ, etc.). Here, λ is the wavelength of the electromagnetic signal emitted by the antenna structure 50.

[0149] The first feed point 540 and the second feed point 550 are configured to be anti-symmetrically fed, meaning that the radio frequency signals fed into the first feed point 540 and the second feed point 550 are both sinusoidal signals. The signals fed into the first feed point 540 and the second feed point 550 have the same frequency, the same amplitude, and a phase difference of 180°. During operation, the current path is as follows... Figure 23As shown by the dotted lines, the portion of the second conductive layer 512 between the first feed point 540 and the second connection portion 530, the second connection portion 530, the portion of the second conductive layer 512 between the second feed point 550 and the second connection portion 530 constitutes an antenna stub. The portion of the second conductive layer 512 between the first feed point 540 and the second connection portion 530, the first connection portion 520, the portion of the second conductive layer 512 between the second feed point 550 and the second connection portion 530, and the first conductive layer 511 between the two first connection portions 520 also constitute an antenna stub. The two antenna stubs resonate simultaneously and radiate electromagnetic signals outward, thereby forming an antenna mode.

[0150] It is understandable that by reasonably setting the distance between the second connecting part 530 and the first slot 560, the resonant frequency of the formed antenna pattern can be adjusted, thereby adjusting the communication frequency band covered by the antenna pattern. For example, appropriately shortening the distance between the second connecting part 530 and the first slot 560 can increase the resonant frequency band of the antenna pattern, allowing the antenna structure 50 to cover a higher communication frequency band.

[0151] In this embodiment, in a plane parallel to the first conductive layer 511, the projection of the first conductive layer 511 at least partially overlaps with the projection of the second conductive layer 512. That is, on the insulating housing 30, the projection of the first conductive layer 511 at least partially overlaps with the projection of the second conductive layer 512. Furthermore, the second conductive layer 512 and the first conductive layer 511 are coupled through the first connection portion 520. Therefore, during operation, while the second conductive layer 512 is fed with radio frequency signals, the first conductive layer 511 is coupled with radio frequency signals. The first conductive layer 511 and the second conductive layer 512 simultaneously radiate electromagnetic signals outward, which can improve the gain and bandwidth of the antenna structure 50.

[0152] Continue to refer to Figure 23 In some examples, the second conductive layer 512 is annular, and its centerline is perpendicular to the insulating housing 30. Multiple second connecting portions 530 are arranged at intervals around the centerline of the second conductive layer 512. Correspondingly, multiple first gaps 560 are provided, with one first gap 560 on the second conductive layer 512 between two adjacent second connecting portions 530. A first feed point 540 is provided on one side of the second conductive layer 512 of each first gap 560, and a second feed point 550 is provided on the other side of the second conductive layer 512. Each first feed point 540 and second feed point 550 can form an antenna pattern. This arrangement allows the antenna structure 50 to form multiple antenna patterns, thereby improving the communication performance of the antenna structure 50.

[0153] It is understood that the communication frequency bands of multiple antenna modes can be different. In this case, the antenna structure 50 can cover multiple communication frequency bands (such as Bluetooth band, WIFI band, GPS band, cellular band, etc.), thereby enriching the communication frequency bands of the antenna structure 50. Of course, multiple antenna modes can also cover the same communication frequency band, with each antenna mode having a different communication area to increase the signal coverage area. This application embodiment does not impose any limitations on this.

[0154] In some examples, the second connection portion 530 is grounded. It is understood that the electronic device may include a ground plane 401, to which the second connection portion 530 may be coupled. The ground plane can assist the antenna structure in transmitting signals outward. Exemplarily, the ground plane 401 may include at least one of the following: a middle plate 101, a ground layer in the main board 40, a ground metal layer in the display panel 20, and a conductive ground layer of the battery.

[0155] Continue to refer to Figure 23 In some examples, the first conductive layer 511 may also be annular, with the center line of the first conductive layer 511 collinear with the center line of the second conductive layer 512. This arrangement can increase the overlapping area of ​​the projection of the first conductive layer 511 and the second conductive layer 512 on the insulating housing 30, allowing more radio frequency signals to be coupled to the first conductive layer 511, thereby further improving the gain of the antenna structure 50.

[0156] In a ring-shaped implementation of the first conductive layer 511, there can be multiple first connecting portions 520, which can be spaced apart around the center line of the first conductive layer 511. This arrangement can improve the uniformity of force on the first conductive layer 511.

[0157] In the implementation of the first conductive layer 511 as a decorative component of the camera device 60, the center line of the first conductive layer 511 is collinear with the center line of the mounting hole 301. That is, the first conductive layer 511 surrounds the outer periphery of the camera device 60, which can further enhance the decorative effect.

[0158] In some examples, there may be two first connecting portions 520 and two connecting portions 530, and correspondingly, there may be two first slots 560, and the antenna structure 50 may generate two antenna modes; the projections of the first connecting portions 520 and the second connecting portions 530 on the insulating housing 30 may at least partially overlap, or the projections of the first connecting portions 520 and the second connecting portions 530 on the insulating housing 30 may be spaced apart.

[0159] In some examples, there can be four first connecting portions 520 and four second connecting portions 530, and correspondingly, there are four first slots 560, so that the antenna structure 50 can generate four antenna patterns; the projections of the first connecting portions 520 and the second connecting portions 530 on the insulating housing 30 can at least partially overlap, or the projections of the first connecting portions 520 and the second connecting portions 530 on the insulating housing 30 can be spaced apart.

[0160] Unlike the embodiments described above, in other embodiments, please refer to... Figure 24 A first slot 560 is disposed on the first conductive layer 511, and the first slot 560 is located on the first conductive layer 511 on one side of the first connecting portion 520. A first feed point 540 is disposed on the first conductive layer 511 on one side of the first slot 560, and a second feed point 550 is disposed on the first conductive layer 511 on the other side of the first slot 560. The first feed point 540 can be disposed close to the first slot 560, for example, the distance between the first feed point 540 and the first slot 560 can be 0.1λ-0.5λ (such as 0.1λ, 0.2λ, 0.5λ, etc.); similarly, the second feed point 550 is disposed close to the second slot, for example, the distance between the second feed point 550 and the first slot 560 can be 0.1λ-0.5λ (such as 0.1λ, 0.2λ, 0.5λ, etc.). Wherein, λ is the wavelength of the electromagnetic signal emitted by the antenna structure 50.

[0161] The first feed point 540 and the second feed point 550 are configured to be anti-symmetrically fed, meaning that the radio frequency signals fed into the first feed point 540 and the second feed point 550 are both sinusoidal signals. The signals fed into the first feed point 540 and the second feed point 550 have the same frequency, the same amplitude, and a phase difference of 180°. During operation, the current path is as follows... Figure 24 As shown by the dashed lines, the portion of the first conductive layer 511 between the first feed point 540 and the first connection portion 520, the first connection portion 520, the second connection portion 530, the portion of the first conductive layer 511 between the second feed point 550 and another first connection portion 520, the other first connection portion 520, and the other second connection portion 530 constitute antenna stubs; the portion of the first conductive layer 511 between the first feed point 540 and the first connection portion 520, the first connection portion 520, the second conductive layer 512 between the two first connection portions 520, the other first connection portion 520, the portion of the first conductive layer 511 between the second feed point 550 and another first connection portion 520 also constitute antenna stubs. The two antenna stubs resonate simultaneously and radiate electromagnetic signals outward, thereby forming an antenna mode.

[0162] It is understandable that by reasonably setting the distance between the first connecting part 520 and the first gap 560, the resonant frequency of the formed antenna pattern can be adjusted, thereby adjusting the communication frequency band covered by the antenna pattern. For example, appropriately shortening the distance between the first connecting part 520 and the first gap 560 can increase the resonant frequency band of the antenna pattern, and the antenna structure 50 can cover a higher communication frequency band.

[0163] In this embodiment, in a plane parallel to the first conductive layer 511, the projection of the first conductive layer 511 at least partially overlaps with the projection of the second conductive layer 512. That is, on the insulating housing 30, the projection of the first conductive layer 511 at least partially overlaps with the projection of the second conductive layer 512. Furthermore, the second conductive layer 512 and the first conductive layer 511 are coupled through the first connection portion 520. Therefore, during operation, the second conductive layer 512 will be coupled with radio frequency signals, and the first conductive layer 511 and the second conductive layer 512 will simultaneously radiate electromagnetic signals outward, which can improve the gain of the antenna structure 50.

[0164] Continue to refer to Figure 24 In some examples, the first conductive layer 511 is annular, and its centerline is perpendicular to the insulating shell 30. Multiple first connecting portions 520 are arranged at intervals around the centerline of the first conductive layer 511. Correspondingly, multiple first gaps 560 are provided, with one first gap 560 on the first conductive layer 511 between two adjacent first connecting portions 520. A first feed point 540 is provided on one side of the first conductive layer 511 of each first gap 560, and a second feed point 550 is provided on the other side of the first conductive layer 511. Each first feed point 540 and second feed point 550 can form an antenna pattern. This arrangement allows the antenna structure 50 to form multiple antenna patterns, thereby improving the communication performance of the antenna structure 50.

[0165] It is understood that the communication frequency bands of multiple antenna modes can be different. In this case, the antenna structure 50 can cover multiple communication frequency bands (such as Bluetooth band, WIFI band, GPS band, cellular band, etc.), thereby enriching the communication frequency bands of the antenna structure 50. Of course, multiple antenna modes can also cover the same communication frequency band, with each antenna mode having a different communication area to increase the signal coverage area. This application embodiment does not impose any limitations on this.

[0166] The first conductive layer 511 serves as the imaging device 60 (e.g. Figure 3 In the implementation of the decorative component shown, the center line of the first conductive layer 511 is collinear with the center line of the mounting hole 301. That is to say, the first conductive layer 511 surrounds the outer periphery of the camera device 60, which can further improve the decorative effect.

[0167] In some examples, the second connection portion 530 is grounded. It is understood that the electronic device may include a ground plane 401, to which the second connection portion 530 may be coupled. Exemplarily, the ground plane 401 may include at least one of the following: a middle plate 101, a grounding layer in the main board 40, a grounding metal layer in the display panel 20, and a conductive grounding layer of the battery.

[0168] Continue to refer to Figure 24 In some examples, the second conductive layer 512 may also be annular, with the center line of the second conductive layer 512 collinear with the center line of the first conductive layer 511.

[0169] In a ring-shaped implementation of the second conductive layer 512, there can be multiple second connecting portions 530, which can be spaced apart around the center line of the second conductive layer 512. This arrangement can improve the uniformity of force on the second conductive layer 512.

[0170] In some examples, there may be two first connecting portions 520 and two connecting portions 530, and correspondingly, there may be two first slots 560, and the antenna structure 50 may generate two antenna modes; the projections of the first connecting portions 520 and the second connecting portions 530 on the insulating housing 30 may at least partially overlap, or the projections of the first connecting portions 520 and the second connecting portions 530 on the insulating housing 30 may be spaced apart.

[0172] Unlike the embodiments described above, in some embodiments, please refer to... Figure 25 and Figure 26 The antenna structure 50 includes a radiating structure 510, which includes a radiating branch 570 and a first conductive layer 511. The first conductive layer 511 is disposed on the insulating housing 30. The radiating branch 570 and the first conductive layer 511 can be disposed at intervals along a direction perpendicular to the insulating housing 30. The radiating branch 570 is disposed on the inner side of the insulating housing 30, that is, the radiating branch 570 is disposed within the accommodating space 103 of the electronic device.

[0173] For example, in an implementation where the electronic device includes a floor 401, the radiating branch 570 may be disposed on the floor 401; in an implementation where the floor 401 includes a grounding layer of the motherboard 40, the radiating branch 570 may be disposed on the same layer as the grounding layer.

[0174] The antenna structure 50 also includes a first connecting part 520, which is disposed between the radiating stub 570 and the first conductive layer 511. The radiating stub 570 is coupled to the first conductive layer 511 through the first connecting part 520. A first slot 560 is provided on the radiating stub 570 on one side of the first connecting part 520. A first feed point 540 is provided on the radiating stub 570 on one side of the first slot 560. A second feed point 550 is provided on the radiating stub 570 on the other side of the first slot 560. The first power supply point 540 can be located close to the first gap 560. For example, the distance between the first power supply point 540 and the first gap 560 can be 0.1mm-5mm (e.g., 0.1mm, 2mm, 5mm, etc.). Similarly, the second power supply point 550 can be located close to the second gap. For example, the distance between the second power supply point 550 and the first gap 560 can be 0.1mm-5mm (e.g., 0.1mm, 2mm, 5mm, etc.).

[0175] The first feed point 540 and the second feed point 550 are configured to be anti-symmetrically fed, meaning that the radio frequency signals fed into the first feed point 540 and the second feed point 550 are both sinusoidal signals. The signals fed into the first feed point 540 and the second feed point 550 have the same frequency, the same amplitude, and a phase difference of 180°. During operation, the current path is as follows... Figure 26 As shown by the dotted lines, the partial radiating stub 570 between the first feed point 540 and the first connecting portion 520, the first connecting portion 520, the second connecting portion 530, the partial first conductive layer 511 between the two second connecting portions 530, another second connecting portion 530, another first connecting portion 520, and the radiating stub 570 between the second feed point 550 and the other first connecting portion 520 constitute antenna stubs; the partial radiating stub 570 between the first feed point 540 and the first connecting portion 520, the first connecting portion 520, the partial second conductive layer 512 between the two first connecting portions 520, the other first connecting portion 520, and the radiating stub 570 between the second feed point 550 and the other first connecting portion 520 also constitute antenna stubs. The two antenna stubs resonate simultaneously and radiate electromagnetic signals outward, thereby forming an antenna mode.

[0176] It is understandable that by reasonably setting the distance between the first connecting part 520 and the first gap 560, the resonant frequency of the formed antenna pattern can be adjusted, thereby adjusting the communication frequency band covered by the antenna pattern. For example, appropriately shortening the distance between the first connecting part 520 and the first gap 560 can increase the resonant frequency band of the antenna pattern, and the antenna structure 50 can cover a higher communication frequency band.

[0177] In this embodiment, in a plane parallel to the first conductive layer 511, the projection of the first conductive layer 511 at least partially overlaps with the projection of the radiating branch 570. That is, in the insulating shell 30 (e.g., Figure 25 As shown, the projection of the first conductive layer 511 at least partially overlaps with the projection of the radiating stub 570; and the first conductive layer 511 and the radiating stub 570 are coupled through the first connection portion 520. Therefore, during operation, while the radiating stub 570 is fed with radio frequency signals, the first conductive layer 511 is coupled with radio frequency signals, thereby simultaneously radiating electromagnetic signals outward, which can improve the gain and bandwidth of the antenna structure 50.

[0178] In some examples, the radiating structure 510 further includes a second conductive layer 512. The first conductive layer 511 and the second conductive layer 512 are arranged parallel to each other and spaced apart. The second conductive layer 512 is disposed between the first conductive layer 511 and the radiating branch 570. The first conductive layer 511 can be attached to the outer surface of the insulating housing 30, and the second conductive layer 512 can be attached to the inner surface of the insulating housing 30. In a plane parallel to the first conductive layer 511, the projection of the first conductive layer 511 and the projection of the second conductive layer 512 at least partially overlap, that is, on the insulating housing 30, the projections of the first conductive layer 511 and the second conductive layer 512 at least partially overlap.

[0179] Continue to refer to Figure 25 and Figure 26 The electronic device also includes a second connection portion 530, which is disposed between the first conductive layer 511 and the second conductive layer 512. The first conductive layer 511 and the second conductive layer 512 are coupled together through the second connection portion 530. The first connection portion 520 is coupled to both the second conductive layer 512 and the radiating stub 570. With this configuration, the radiating stub 570 can couple signals to the first conductive layer 511 and the second conductive layer 512, thereby enabling the first conductive layer 511 and the second conductive layer 512, along with the radiating stub 570, to simultaneously radiate signals outward, further improving the gain of the antenna structure 50.

[0180] In some examples, the radiating stub 570 is ring-shaped, and its centerline can be perpendicular to the insulating housing 30. Correspondingly, there are multiple first connecting portions 520, spaced apart around the centerline of the radiating stub 570. A first slot 560 is provided on each radiating stub 570 between adjacent first connecting portions 520. A first feed point 540 is provided on one side of each first slot 560, and a second feed point 550 is provided on the other side of each first slot 560. With this configuration, each first feed point 540 and its corresponding second feed point 550 can form an antenna pattern. This configuration allows the antenna structure 50 to form multiple antenna patterns, thereby improving its communication performance.

[0181] It is understood that the communication frequency bands of multiple antenna modes can be different. In this case, the antenna structure 50 can cover multiple communication frequency bands (such as Bluetooth band, WIFI band, GPS band, cellular band, etc.), thereby enriching the communication frequency bands of the antenna structure 50. Of course, multiple antenna modes can also cover the same communication frequency band, with each antenna mode having a different communication area to increase the signal coverage area. This application embodiment does not impose any limitations on this.

[0182] In some examples, the first conductive layer 511 and the second conductive layer 512 can both be annular, with the center lines of the first conductive layer 511 and the second conductive layer 512 collinear. The center line of the first conductive layer 511 is perpendicular to the insulating shell 30, and the center line of the first conductive layer 511 is collinear with the center line of the radiating structure 510. That is, the center lines of the first conductive layer 511, the second conductive layer 512, and the radiating structure 510 are all collinear. This arrangement can increase the overlapping area of ​​the projection of the radiating branch 570 and the conductive layer on the insulating shell 30, further enabling the radiating branch 570 to couple radio frequency signals to the first conductive layer 511 and the second conductive layer 512, thereby further improving the gain of the antenna structure 50.

[0183] In the above implementation, there are multiple second connecting portions 530, which are spaced apart around the center line of the first conductive layer 511. This arrangement can improve the uniformity of force distribution on the first conductive layer 511.

[0184] The first conductive layer 511 serves as the imaging device 60 (e.g. Figure 3 In the implementation of the decorative component shown, the center line of the first conductive layer 511 is collinear with the center line of the mounting hole 301. That is to say, the first conductive layer 511 surrounds the outside of the camera device 60, which can further improve the decorative effect.

[0185] In some examples, there may be two first connecting portions 520 and two connecting portions 530, and correspondingly, there may be two first slots 560, and the antenna structure 50 may generate two antenna modes; the projections of the first connecting portions 520 and the second connecting portions 530 on the insulating housing 30 may at least partially overlap, or the projections of the first connecting portions 520 and the second connecting portions 530 on the insulating housing 30 may be spaced apart.

[0186] In some examples, there can be four first connecting portions 520 and four second connecting portions 530, and correspondingly, there are four first slots 560, so that the antenna structure 50 can generate four antenna patterns; the projections of the first connecting portions 520 and the second connecting portions 530 on the insulating housing 30 can at least partially overlap, or the projections of the first connecting portions 520 and the second connecting portions 530 on the insulating housing 30 can be spaced apart.

[0187] In an embodiment where the antenna structure 50 has a first slot 560, the electronic device may further include a radio frequency (RF) device and a switching device. The RF device is coupled to each first feed point 540 and second feed point 550 via the switching device. The switching device has multiple operating states, and in different operating states, the switching device couples the RF device to the first feed point 540 and second feed point 550 corresponding to different first slots 560. With this configuration, the switching device can control the antenna structure 50 to generate different antenna modes.

[0188] For example, the radio frequency device may include a radio frequency chip that generates a radio frequency signal after receiving a baseband signal, and the radio frequency chip can filter and / or amplify the radio frequency signal, thereby feeding the radio frequency signal into a switching device, which feeds the radio frequency signal into a corresponding first feed point 540 and a second feed point 550.

[0189] In some examples, the switching device is configured to sequentially switch between different operating states, that is, the switching device sequentially couples the first feed point 540 and the second feed point 550 corresponding to different first gaps 560 with the radio frequency device, and the antenna structure 50 sequentially switches between different antenna modes. In each operating state, the communication area corresponding to the radiating structure 510 is different, thereby realizing the beam scanning of electromagnetic signals and increasing the signal coverage area.

[0190] For example, each antenna mode of the antenna structure 50 can cover the same communication frequency band (such as Bluetooth band, WIFI band, GPS band, cellular band). The communication area corresponding to the radiating structure 510 is different in each antenna mode. By switching the working devices in sequence, the antenna structure 50 can switch different antenna modes in sequence, thereby scanning different areas in sequence and increasing the signal coverage area.

[0191] In some examples, the communication frequency band corresponding to the antenna structure 50 is different under different operating states of the switching device. This setting allows the antenna structure 50 to cover different communication frequency bands, thereby increasing the bandwidth of the antenna structure 50.

[0192] In other examples, the electronic device includes a radio frequency (RF) device and a phase-shifting device. The RF device is coupled to each first feed point 540 and second feed point 550 via the phase-shifting device. The phase-shifting device is used to sequentially adjust the phase of each first feed point 540 and second feed point 550. Each first feed point 540 has a different phase, and the communication area of ​​the antenna pattern corresponding to each first feed point 540 is different, thereby changing the communication area corresponding to the radiating structure 510. With this configuration, by sequentially adjusting the phase of the RF signal fed into each first feed point 540 via the phase-shifting device, the communication area of ​​the radiating structure 510 changes sequentially, thereby achieving beam scanning of different areas and increasing the signal coverage area.

[0193] For example, the phase shifting device may include multiple phase shifters, each of which may include an output port. The output port of each phase shifter outputs a radio frequency signal with a different phase. The output port of each phase shifter is coupled to a first feed point 540. The multiple phase shifters sequentially transmit radio frequency signals, thereby enabling the antenna structure 50 to generate different antenna modes to cover different communication areas.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the protection scope of this application. Therefore, the protection scope of this application should be determined by the protection scope of the claims.
