Technical Field

[0001] This application relates to the field of wireless communication, in particular to a camera decoration component and an electronic device. Background Art

[0002] In current terminal electronic devices, the frame part is mainly used as an antenna radiator. As the structural design of electronic devices gradually develops towards compactness and thinness, the challenge to antenna performance is gradually increasing. As the functions that electronic devices need to support increase, more requirements are put forward for the bandwidth, efficiency, radiation pattern, etc. of the antenna. The limited design space of the antenna in the electronic device restricts the performance of the antenna. Summary of the Invention

[0003] Embodiments of this application provide a camera decoration component and an electronic device, aiming to set an antenna radiator in the internal space of the camera decoration component to relieve the antenna layout pressure on the frame of the electronic device and improve the antenna performance of the electronic device.

[0004] In a first aspect, a camera decoration component is provided. The camera decoration component includes a decoration body, the decoration body includes a metal part, and at least part of the metal part forms a first radiator. The camera decoration component is used to be installed on the housing of an electronic device. The first radiator includes a first feeding point and at least one first grounding point arranged at intervals. The first feeding point is used to be electrically connected to the first feeding end of the electronic device, and the first grounding point is used to be electrically connected to the ground plane of the electronic device. The antenna device of the electronic device is used to communicate in a first frequency band, the first radiator is used to support communication in the first frequency band, and the antenna device and the first radiator are electrically connected to the same radio frequency chip.

[0005] It can be understood that the camera decoration component in this embodiment may include a decoration body. Among them, the decoration body may include a metal part. At least part of the metal part may be used to form a first radiator. The antenna device of the electronic device is used to operate in a first frequency band, and the first radiator may be used to support communication in the first frequency band, that is, the first radiator may be of the same frequency as the antenna device. The first radiator and the antenna device are electrically connected to the same radio frequency chip. In this way, the first radiator and the antenna device may serve as a receiving antenna with the same function and perform diversity synthesis through the same radio frequency chip to achieve the improvement of antenna performance. At the same time, the first radiator is formed by at least part of the metal part of the decoration body, and the metal part of the decoration body can achieve "multiple uses of one thing", so that the first radiator can improve the antenna performance on the basis of not occupying the limited antenna layout space on the side of the electronic device, which is beneficial to relieving the antenna layout pressure on the frame of the electronic device.

[0006] In one possible implementation, the first frequency band corresponds to the satellite communication frequency band and is used to support satellite messaging, and / or satellite phone, and / or satellite Internet access. In this way, by setting the first radiator and the antenna device to be electrically connected to the same satellite communication chip / radio frequency chip, the satellite communication performance of the electronic device can be improved, thereby effectively enhancing the user experience when using the electronic device for satellite communication.

[0007] In one possible implementation, a first frame radiator is provided on the frame of the electronic device. The antenna device includes the first frame radiator. The first radiator is disposed at an interval from the first frame radiator, and the first frame radiator and the first radiator are electrically connected to the same radio frequency chip. In this way, the first frame radiator and the first radiator are electrically connected to the same radio frequency chip, and diversity synthesis is performed through the same radio frequency chip to achieve an improvement in antenna performance.

[0008] In one possible implementation, the first frame radiator is provided on the top edge of the electronic device. In this way, when the first frame radiator is used as a satellite antenna radiator, arranging the first frame radiator on the top edge of the electronic device is conducive to facilitating the user to align the antenna with the satellite, improving the signal reception sensitivity, and enhancing the user experience.

[0009] In one possible implementation, the electronic device further includes a first side edge and a second side edge. The first side edge and the second side edge are fixed on two opposite sides of the top edge. The distance from the decorative part body to the first side edge is a first distance, and the distance from the decorative part body to the second side edge is a second distance. The ratio of the first distance to the second distance is within the range of 0.8 to 1.2. In this way, the decorative part body can be arranged relatively centered with respect to the first side edge and the second side edge. When the first frame radiator is provided on the top edge, the radiation pattern of the first radiator can be complementary to the radiation pattern of the first frame radiator, and the first radiator and the first frame radiator can synthesize a wide beam, so that the radiation formed by the first radiator and the first frame radiator together can have good transmission and reception capabilities in a relatively wide direction.

[0010] In one possible implementation, the first frame radiator has a first open end, a second open end, and a conductive part extending between the first open end and the second open end in the length extension direction of the top edge. The distance from the center of the top edge to the first open end is a first spacing, and the distance from the center of the top edge to the second open end is a second spacing. The ratio of the first spacing to the second spacing is within the range of 0.8 to 1.2. In this way, the first frame radiator can be provided on the top edge and is located at the middle position of the top edge. When the first frame radiator is a satellite antenna radiator, it is conducive to facilitating the user to align the antenna with the satellite, improving the signal reception sensitivity, and enhancing the user experience.

[0011] In one possible implementation, both the antenna device and the first radiator are used to receive signals in the first frequency band.

[0012] It can be understood that the first radiator and the antenna device can serve as receiving antennas with the same function, and perform diversity synthesis through the same radio frequency chip, so as to expand the radiation pattern, or expand the beam, or expand the bandwidth, which is beneficial to enhancing the receiving signal ability of the electronic device in the first frequency band to improve the antenna performance. For example, when a user conducts satellite communication, it is necessary to point the maximum radiation direction of the antenna at the satellite to establish communication with the satellite. When the beam of the antenna is narrow (for example, below ±10°), the requirement for pointing at the satellite by the antenna is high, and the change in the attitude of the electronic device has a great impact on the quality of satellite communication. When the beam of the antenna is wide (for example, above ±30°), the requirement for pointing at the satellite is low, and the change in the attitude of the electronic device has a small impact on the quality of satellite communication. The radiation pattern generated by the first radiator in this embodiment can be complementary to the radiation pattern generated by the antenna device, and a wide beam can be synthesized, so as to expand the radiation pattern and the beam, which is beneficial to reducing the requirement for pointing at the satellite during satellite communication of the electronic device, thereby effectively reducing the impact of the change in the attitude of the electronic device on the quality of satellite communication and improving the satellite communication performance of the electronic device. Among them, both the antenna device and the first radiator are used to receive signals in the satellite communication frequency band. In this way, the radiation pattern generated by the first radiator can be complementary to the radiation pattern generated by the antenna device to synthesize a wide beam and broaden the receiving beam, so that when the user uses the electronic device to receive satellite signals, the receiving sensitivity is high, which is beneficial to enhancing the signal receiving ability of the electronic device and improving the user experience.

[0013] In a possible implementation manner, the camera decoration component further includes a second radiator, the second radiator is fixed to the first radiator, and the second radiator includes a second feeding point for electrically connecting to the second feeding end of the electronic device.

In this way, the second radiator can be arranged closely to the first radiator, and the two can share the space of the camera decoration component, so that on the basis of not occupying the limited antenna layout space in the frame of the electronic device, the antenna performance can be improved, which is beneficial to releasing the antenna layout pressure of the frame of the electronic device.

[0015] In a possible implementation manner, the second radiator is an NFC coil or a wireless charging coil. In this way, the first radiator and the second radiator can share the space of the camera decoration component, so that on the basis of not occupying the limited antenna layout space in the frame of the electronic device, the antenna performance can be improved, which is beneficial to releasing the antenna layout pressure of the frame of the electronic device.

[0017] It can be understood that the camera decoration component in this embodiment may include a first radiator and a second radiator. The first radiator may be constituted by at least part of the metal part of the decoration body. The first radiator and the second radiator may be radiators of two different antennas. The second radiator may be fixedly connected to the surface of the first radiator. In this way, the second radiator can be arranged closely to the first radiator, and the two can share the space of the camera decoration component, so that on the basis of not occupying the limited antenna layout space in the frame of the electronic device, the antenna performance can be improved, which is beneficial to releasing the antenna layout pressure of the frame of the electronic device.

[0018] In a possible implementation, the second radiator is an NFC coil or a wireless charging coil. In this way, the first radiator and the second radiator can share the space of the camera decoration component, so that on the basis of not occupying the limited antenna layout space in the frame of the electronic device, the antenna performance can be improved, which is beneficial to releasing the antenna layout pressure of the frame of the electronic device.

[0019] In a possible implementation, the camera decoration component further includes an isolation layer, the isolation layer is fixed between the first radiator and the second radiator, and the material of the isolation layer is ferrite or nanocrystalline. In this way, the isolation layer can exhibit the characteristics of a magnetic conductor at low frequencies and the characteristics of an electrical conductor with a low conductivity at high frequencies, so as to avoid resonance between the second radiator and the first radiator, and the isolation degree between the second radiator and the first radiator is relatively good.

[0020] In a possible implementation, the camera decoration component further includes an inductance structure, and the inductance structure is connected in series between the second feeding point and the feeding end of the electronic device. In this way, by connecting the inductance structure in series with the second feeding point, the inductance structure can act as a low-pass filter to cut off the high-frequency signal input to the second radiator and avoid the influence of clutter.

[0021] In a possible implementation, the camera decoration component further includes a third radiator. The first radiator is provided with a groove, and at least a part of the third radiator is received in the groove. The third radiator includes a third feeding point for electrically connecting to a third feeding end of the electronic device.

[0022] It can be understood that the camera decoration component in this embodiment may further include a third radiator, and the third radiator may be at least partially disposed in the groove of the first radiator. In this way, the first radiator and the third radiator can share the space of the camera decoration component, so that the antenna performance can be improved without occupying the limited antenna layout space in the frame of the electronic device, which is beneficial to relieve the antenna layout pressure on the frame of the electronic device.

[0023] In a possible implementation, the first radiator is used to support communication in a first frequency band; and / or the third radiator is used to support communication in a second frequency band. In this way, the first radiator and the third radiator can operate in different frequency bands, so that the antenna performance can be improved without occupying the limited antenna layout space in the frame of the electronic device, which is beneficial to relieve the antenna layout pressure on the frame of the electronic device.

[0024] In a third aspect, a camera decoration component is provided. The camera decoration component includes a decoration body, and the decoration body includes a metal part. At least a part of the metal part forms a first radiator. The first radiator is provided with a groove. The camera decoration component further includes a third radiator, and at least a part of the third radiator is received in the groove. The first radiator is used for communication in a first frequency band, and the third radiator is used for communication in a second frequency band. The camera decoration component is used to be mounted on a housing of an electronic device. The first frequency band and the second frequency band include different communication frequency bands. The first radiator includes a first feeding point and at least one first grounding point arranged at intervals. The first feeding point is used for electrically connecting to a first feeding end of the electronic device, and the first grounding point is used for electrically connecting to a ground plane of the electronic device.

[0025] It can be understood that the camera decoration component in this embodiment may further include a third radiator, and the third radiator may be at least partially disposed in the groove of the first radiator. In this way, the first radiator and the third radiator can share the space of the camera decoration component, so that the antenna performance can be improved without occupying the limited antenna layout space in the frame of the electronic device, which is beneficial to relieve the antenna layout pressure on the frame of the electronic device.

[0026] In a possible implementation, the third radiator includes a third grounding point and a third feeding point arranged at intervals. The third grounding point is electrically connected to the first radiator, and the third feeding point is electrically connected to a third feeding end of the electronic device. In this way, the first radiator can also serve as a reference ground for the third radiator.

[0027] In a possible implementation, the camera decoration component further includes a feeder and at least one feeder grounding member. A through hole is provided at the bottom of the groove. One end of the feeder is electrically connected to the third feeding point, and the other end of the feeder passes through the through hole and is electrically connected to the third feeding end of the electronic device. One end of the feeder grounding member is connected to the bottom wall of the groove, and the other end of the feeder grounding member is electrically connected to the ground plane of the electronic device. The feeder grounding member is located between the feeder and the inner wall of the through hole. In this way, the impedance of the third feeding point of the third radiator can be adjusted by setting the feeder grounding member, improving the antenna performance.

[0028] In a possible implementation, the camera decoration component further includes a fourth radiator. At least a part of the fourth radiator is received in the groove and is spaced apart from the third radiator. The fourth radiator includes a fourth grounding point, and the fourth grounding point is electrically connected to the ground plane of the electronic device. The fourth radiator couples with the third radiator.

[0029] It can be understood that in this embodiment, a composite antenna is formed by arranging the fourth radiator and the third radiator in the groove. Among them, the third radiator can be used as the main radiator, and the fourth radiator can be used as the parasitic radiator. In this way, the composite antenna formed by the third radiator and the fourth radiator can generate two resonant frequency bands, and the two resonant frequency bands are continuous, which is beneficial to broadening the bandwidth of the composite antenna and improving the antenna performance. At the same time, the fourth radiator can reuse the space of the camera decoration component, so that on the basis of not occupying the limited antenna layout space in the frame of the electronic device, the antenna performance can be improved, which is beneficial to releasing the antenna layout pressure of the frame of the electronic device.

[0030] In a possible implementation, the third radiator further includes a fourth feeding point. The fourth feeding point is electrically connected to the fourth feeding end of the electronic device. The third feeding point excites a first current on the third radiator, and the fourth feeding point excites a second current on the third radiator. The direction of the first current is orthogonal to the direction of the second current.

[0031] It can be understood that the third radiator in this embodiment includes a third feeding point and a fourth feeding point. The third feeding point and the fourth feeding point can respectively excite a first current in the first direction and a second current in the second direction on the third radiator. The first current and the second current are orthogonal. That is to say, the third feeding point and the fourth feeding point can respectively excite a transverse mode and a longitudinal mode on the third radiator. The third radiator can be extended to a dual-antenna structure of a co-radiator through the excitation of the transverse and longitudinal modes to improve the antenna performance of the electronic device.

[0032] Fourthly, an electronic device is provided. The electronic device includes a housing, a camera module, and the above-mentioned camera decoration component. The housing includes a middle frame and a rear cover. The camera module is fixed to the middle frame. The rear cover is provided with a light-transmitting hole, and the light incident hole of the camera module is exposed relative to the light-transmitting hole. The camera decoration component is fixed to the rear cover and covers the light-transmitting hole. An avoidance hole is provided on the decoration part body of the camera decoration component, and the avoidance hole is arranged opposite to the light incident hole of the camera module.

[0033] It can be understood that the camera decoration component in this embodiment may include a decoration part body. Among them, the decoration part body may include a metal part. At least part of the metal part can be used to form a first radiator. The antenna device of the electronic device is used to operate in the first frequency band. The first radiator can be used to support communication in the first frequency band, that is, the first radiator can be of the same frequency as the antenna device. The first radiator and the antenna device are electrically connected to the same radio frequency chip. In this way, the first radiator and the antenna device can be used as a receiving antenna with the same function and perform diversity synthesis through the same radio frequency chip to improve the antenna performance. At the same time, the first radiator is formed by at least part of the metal part of the decoration part body. The metal part of the decoration part body can achieve "one thing with multiple uses", so that the first radiator can improve the antenna performance without occupying the limited antenna layout space on the edge of the electronic device, which is beneficial to releasing the antenna layout pressure on the frame of the electronic device.

[0034] In a possible implementation manner, the first radiator includes a first region and a second region. The projection of the first region in the thickness direction of the electronic device does not cover the camera module, and the projection of the second region in the thickness direction of the electronic device covers the camera module. The first radiator includes a first feeding point and at least one first grounding point, and both the first feeding point and the multiple first grounding points are located in the first region. In this way, both the first feeding point and the first grounding point can be arranged to avoid the camera module, avoiding affecting the antenna performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] Hereinafter, the terms that may appear in the embodiments of the present application will be explained.

[0059] It should be understood that the term "and / or" used herein is only a description of the same field of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0060] The term "within... range" used in the present application, unless otherwise specified as not including the end values, defaults to including the two end values of the range. For example, within the range of 1 to 5, both the values 1 and 5 are included.

[0061] Coupling: It can be understood as direct coupling and / or indirect coupling. "Coupling connection" can be understood as direct coupling connection and / or indirect coupling connection. Direct coupling can also be called "electrical connection", which is understood as physical contact and electrical conduction between components; it can also be understood as a form of connection between different components in a circuit structure through physical lines such as copper foils or wires of a printed circuit board (PCB) that can transmit electrical signals. "Indirect coupling" can be understood as electrical conduction between two conductors in a non-contact manner through air. In one embodiment, indirect coupling can also be called capacitive coupling. For example, signal transmission is achieved by forming an equivalent capacitance through the coupling between the gaps between two conductive parts.

[0062] Element / Device: Includes at least one of lumped elements / devices and distributed elements / devices.

[0063] Lumped Element / Device: It refers to the general term for all elements when the size of the element is much smaller than the wavelength corresponding to the operating frequency of the circuit. For a signal, at any moment, the characteristics of the element always remain fixed and are independent of frequency.

[0064] Distributed Element / Device: Different from lumped elements, when the size of the element is about the same as or larger than the wavelength corresponding to the operating frequency of the circuit, when a signal passes through the element, the characteristics of each point of the element itself will vary with the change of the signal. At this time, the element as a whole cannot be regarded as a single entity with fixed characteristics, but should be called a distributed element.

[0065] Capacitance: It can be understood as lumped capacitance and / or distributed capacitance. Lumped capacitance refers to components with capacitive properties, such as capacitor elements; distributed capacitance (or distributed capacitor) refers to the equivalent capacitance formed by a certain gap between two conductive parts.

[0066] Inductance: It can be understood as lumped inductance and / or distributed inductance. Lumped inductance refers to components with inductive properties, such as inductor elements; distributed inductance (or distributed inductor) refers to the equivalent inductance formed by a conductive part of a certain length.

[0067] Radiator: It is a device in an antenna used to receive / transmit electromagnetic wave radiation. In some cases, "antenna" is narrowly understood as a radiator, which converts the 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 through a feeder line. Through the radiator, it is converted into electromagnetic wave energy of a certain polarization and radiated in the required direction. The receiving radiator converts the electromagnetic wave energy of a certain polarization from a specific direction in space back into modulated high-frequency current energy and transmits it to the input end of the receiver through a feeder line.

[0068] The radiator may include a conductor with a specific shape and size, such as linear, sheet-like, etc. The present application does not limit the specific shape. In one embodiment, the linear radiator may be simply referred to as a wire antenna. In one embodiment, the linear radiator may be implemented by a conductive frame and may also be referred to as a frame antenna. In one embodiment, the linear radiator may be implemented by a support conductor and may also be referred to as a support antenna. In one embodiment, the wire diameter (e.g., including thickness and width) of the linear radiator, or the radiator of the wire antenna, is much smaller than the wavelength (e.g., the dielectric wavelength) (e.g., less than 1 / 16 of the wavelength), and the length can be comparable to the wavelength (e.g., the dielectric wavelength) (e.g., the length is around 1 / 8 of the wavelength, or 1 / 8 to 1 / 4, or 1 / 4 to 1 / 2, or longer). The main forms of wire antennas include dipole antennas, half-wave dipole antennas, monopole antennas, loop antennas, inverted-F antennas (also known as IFA, Inverted F Antenna). For example, for a dipole antenna, each dipole antenna generally includes two radiating branches, and each branch is fed by a feeding part from the feeding end of the radiating branch. For example, an inverted-F antenna (Inverted-F Antenna, IFA) can be regarded as obtained by adding a grounding path to a monopole antenna. The IFA antenna has a feeding point and a grounding point and is called an inverted-F antenna because its side view is in the shape of an inverted F. In one embodiment, the sheet radiator may include a microstrip antenna, or a patch antenna, such as a planar inverted-F antenna (also known as PIFA, Planar Inverted F Antenna). In one embodiment, the sheet radiator may be implemented by a planar conductor (such as a conductive sheet or a conductive coating, etc.). In one embodiment, the sheet radiator may include a conductive sheet, such as a copper sheet, etc. In one embodiment, the sheet radiator may include a conductive coating, such as silver paste, etc. The shapes of the sheet radiator include circular, rectangular, annular, etc. The present application does not limit the specific shape. The structure of a microstrip antenna generally consists of a dielectric substrate, a radiator, and a ground plane, where the dielectric substrate is disposed between the radiator and the ground plane.

[0069] The radiator may also include slots or slits formed on a conductor. For example, closed or semi-closed slots or slits are formed on a grounded conductor surface. In one embodiment, the slotted or slit radiator may be simply referred to as a slot antenna or a slit antenna. In one embodiment, the radial dimension (e.g., including width) of the slot or slit of the slot antenna / slit antenna is much smaller than the wavelength (e.g., the dielectric wavelength) (e.g., less than 1 / 16 of the wavelength), and the length dimension may be comparable to the wavelength (e.g., the dielectric wavelength) (e.g., around 1 / 8 of the wavelength, or 1 / 8 to 1 / 4, or 1 / 4 to 1 / 2, or longer). In one embodiment, the radiator with a closed slot or slit may be simply referred to as a closed slot antenna. In one embodiment, the radiator with a semi-closed slot or slit (e.g., adding an opening to a closed slot or slit) may be simply referred to as an open slot antenna. In some embodiments, the shape of the slit is elongated. In some embodiments, the length of the slit is about half a wavelength (e.g., the dielectric wavelength). In some embodiments, the length of the slit is about an integer multiple of the wavelength (e.g., one dielectric wavelength). In some embodiments, the slit can be fed by a transmission line bridged on one or both of its sides. Thus, a radio frequency electromagnetic field is excited on the slit and radiates electromagnetic waves into space. In one embodiment, the radiator of the slot antenna or slit antenna can be realized by a conductive frame grounded at both ends, and can also be referred to as a frame antenna; in this embodiment, it can be considered that the slot antenna or slit antenna includes a linear radiator, the linear radiator is spaced from the floor and grounded at both ends of the radiator, thereby forming a closed or semi-closed slot or slit. In one embodiment, the radiator of the slot antenna or slit antenna can be realized by a support conductor grounded at both ends, and can also be referred to as a support antenna.

[0070] The feeding circuit is a combination of all circuits for receiving and transmitting radio frequency signals. The feeding circuit may include a transceiver and an RF front end circuit. In some cases, "feeding circuit" is narrowly understood as an RFIC (Radio Frequency Integrated Circuit), and an RFIC can be considered to include an RF front end chip and a transceiver. The feeding circuit has the function of converting radio waves (e.g., radio frequency signals) and electrical signals (e.g., digital signals). Generally, it is considered to be part of the radio frequency.

[0071] In some embodiments, the electronic device may further include a test socket (or referred to as a radio frequency socket or radio frequency test socket). This test socket can be used to insert a coaxial cable to test the characteristics of the RF front end circuit or the radiator of the antenna through the cable. The RF front end circuit can be considered as the circuit part coupled between the test socket and the transceiver.

[0072] In some embodiments, the radio frequency front-end circuit can be integrated into a radio frequency front-end chip in an electronic device, or the radio frequency front-end circuit and the transceiver can be integrated into a radio frequency chip in the electronic device.

[0073] It should be understood that any two of the first / second / ... / Nth feeding circuits in the present application can share the same transceiver. For example, signals are transmitted through a radio frequency channel in a transceiver (e.g., a port (pin) of a radio frequency chip); they can also share a radio frequency front-end circuit. For example, signals are processed by a tuning circuit or an amplifier in a radio frequency front-end.

[0074] It should also be understood that two of the first / second / ... / Nth feeding circuits in the present application generally correspond to two radio frequency test sockets in an electronic device.

[0075] A matching circuit is a circuit used to adjust the radiation characteristics of an antenna. In one embodiment, the matching circuit is coupled between the feeding circuit and the corresponding radiator. In one embodiment, the matching circuit is coupled between the test socket and the radiator. Generally, the matching circuit is a combination of circuits coupled between the radiator and the ground plane. In one embodiment, the matching circuit can include a tuning circuit and / or electronic components. The tuning circuit can be an electronic component for switching the coupled connection of the radiator. The matching circuit has the functions of impedance matching and / or frequency tuning. Generally, it is considered to be a part of the antenna.

[0076] A grounding structure / feeding structure. The grounding structure / feeding structure can include connecting members, such as metal shrapnel. The radiator is coupled to the ground plane through the grounding structure / the feeding structure is coupled to the feeding circuit. In some embodiments, the feeding structure can include a transmission line / feeding wire, and the grounding structure can include a grounding wire.

[0077] Terminal / Point: The "terminal / point" in the first terminal / second terminal / feeding terminal / grounding terminal / feeding point / grounding point / connection point of the antenna radiator should not be narrowly understood as necessarily being an end point or end part physically disconnected from other radiators. It can also be considered as a certain point or a certain section on a continuous radiator. In one embodiment, the "terminal / point" can include the connection / coupling area on the antenna radiator that is coupled to other conductive structures. For example, the feeding terminal / feeding point can be the coupling area on the antenna radiator that is coupled to the feeding structure or feeding circuit (for example, the area facing a part of the feeding circuit). Another example is that the grounding terminal / grounding point can be the connection / coupling area on the antenna radiator that is coupled to the grounding structure or grounding circuit. Open end / Closed end: In some embodiments, the open end and the closed end are, for example, defined relative to whether they are grounded. The closed end is grounded and the open end is not grounded. In some embodiments, the open end and the closed end are, for example, defined relative to other conductive bodies. The closed end is electrically connected to other conductive bodies and the open end is not electrically connected to other conductive bodies. In one embodiment, the open end can also be referred to as a floating end, a free end, an open end, or an open-circuit end. In one embodiment, the closed end can also be referred to as a grounding terminal or a short-circuit end. It should be understood that in some embodiments, other conductive bodies can be coupled through the open end to transfer coupled energy (which can be understood as transferring current).

[0078] In some embodiments, the understanding of the "closed end" can also be from the perspective of current distribution. The closed end or the grounding terminal, etc., can be understood as the point of large current on the radiator, or can also be understood as the point of small electric field on the radiator. In one embodiment, coupling electronic devices (such as capacitors, inductors, etc.) through the closed end may not change the current distribution characteristics of its point of large current / point of small electric field. In one embodiment, opening a slit (such as a slit filled with insulating material) at or near the closed end may not change the current distribution characteristics of its point of large current / point of small electric field.

[0079] In some embodiments, the understanding of the "open end" can also be from the perspective of current distribution. The open end or the floating end, etc., can be understood as the point of small current on the radiator, or can also be understood as the point of large electric field on the radiator. In one embodiment, coupling electronic devices (such as capacitors, inductors, etc.) through the open end may not change the current distribution characteristics of its point of small current / point of large electric field.

[0080] It should be understood that coupling an electronic device (such as a capacitor, an inductor, etc.) to the radiator end at a slit (from the perspective of the radiator structure, similar to the opening of an open end or a floating end) can make the radiator end at this slit a point of large current / point of small electric field. In this case, it should be understood that the radiator end at this slit is actually a closed end or a grounding terminal, etc.

[0081] The "floating radiator" mentioned in the embodiments of the present application refers to a radiator that is not directly connected to the feeder / feeding stub and / or the ground wire / grounding stub, but is fed and / or grounded through an indirect coupling method.

[0082] It should be understood that the "floating end" and "floating radiator" do not mean that there is no structure around the radiator to support it. In one embodiment, the floating radiator can be, for example, a radiator disposed on the inner surface of an insulating rear cover.

[0083] The current in the same direction / opposite direction mentioned in the embodiments of the present application should be understood as the direction of the main current on the conductors on the same side being in the same direction / opposite direction. For example, when exciting a current distributed in the same direction (e.g., the current path is also bent or circular) on a conductor in a bent or circular shape, it should be understood that, for example, although the main currents excited on the two sides of the circular conductor (e.g., the conductors around a gap, on the conductors on both sides of the gap) are in opposite directions when viewed from the direction, it still belongs to the definition of the current distributed in the same direction in the embodiments of the present application. In one embodiment, the current in the same direction on a conductor can mean that there is no reverse point in the current on the conductor. In one embodiment, the current in the opposite direction on a conductor can mean that there is at least one reverse point in the current on the conductor. In one embodiment, the current in the same direction on two conductors can mean that there is no reverse point in the currents on both conductors and they flow in the same direction. In one embodiment, the current in the opposite direction on two conductors can mean that there is no reverse point in the currents on both conductors and they flow in opposite directions. The current in the same direction / opposite direction on multiple conductors can be understood accordingly.

[0084] Resonance / resonant frequency: The resonant frequency is also called the resonance frequency. The resonant frequency can have a frequency range, that is, the frequency range where resonance occurs. The frequency corresponding to the strongest resonance point is the center frequency point. The return loss characteristic of the center frequency can be less than -20 dB. It should be understood that if there is no additional explanation, the antenna / radiator mentioned in the present application generates "the first / second... resonance", where the first resonance should be the fundamental mode resonance generated by the antenna / radiator, or in other words, the resonance with the lowest frequency generated by the antenna / radiator. It should be understood that the antenna / radiator can generate one or more antenna modes according to the specific design, and each antenna mode can correspondingly generate a fundamental mode resonance.

[0085] Resonant frequency band: The range of the resonant frequency is the resonant frequency band, and the return loss characteristic at any frequency point within the resonant frequency band can be less than -6 dB or -5 dB.

[0086] Communication Band / Operating Band: Regardless of the type of antenna, it always operates within a certain frequency range (bandwidth). For example, an antenna supporting Band B40 has an operating band that includes frequencies in the range of 2300 MHz to 2400 MHz, or in other words, the operating band of this antenna includes Band B40. The frequency range that meets the index requirements can be regarded as the operating band of the antenna.

[0087] The resonant band and the operating band can be the same or can partially overlap. In one embodiment, one or more resonant bands of the antenna can cover one or more operating bands of the antenna.

[0088] Electrical Length: It can refer to the ratio of the physical length (i.e., mechanical length or geometric length) to the wavelength of the transmitted electromagnetic wave. The electrical length can satisfy the following formula:

[0089]

[0090] where L is the physical length and λ is the wavelength of the electromagnetic wave.

[0091] Wavelength: Or the operating wavelength, which can be the wavelength corresponding to the center frequency of the resonant frequency or the center frequency of the operating band supported by the antenna. For example, assuming the center frequency of the B1 uplink band (resonant frequency from 1920 MHz to 1980 MHz) is 1955 MHz, then the operating wavelength can be the wavelength calculated using this frequency of 1955 MHz. Not limited to the center frequency, the "operating wavelength" can also refer to the wavelength corresponding to a non - center frequency of the resonant frequency or the operating band.

[0092] It should be understood that the wavelength of the radiation signal in air can be calculated as follows: (air wavelength, or vacuum wavelength) = speed of light / frequency, where the frequency is the frequency of the radiation signal (MHz), and the speed of light can be taken as 3×10^8 m / s. The wavelength of the radiation signal in a medium can be calculated as follows: where ε is the relative permittivity of the medium. The wavelength in the embodiments of this application usually refers to the medium wavelength, which can be the medium wavelength corresponding to the center frequency of the resonant frequency or the center frequency of the operating band supported by the antenna. For example, assuming the center frequency of the B1 uplink band (resonant frequency from 1920 MHz to 1980 MHz) is 1955 MHz, then the wavelength can be the medium wavelength calculated using this frequency of 1955 MHz. Not limited to the center frequency, the "medium wavelength" can also refer to the medium wavelength corresponding to a non - center frequency of the resonant frequency or the operating band. For ease of understanding, the medium wavelength mentioned in the embodiments of this application can be simply calculated through the relative permittivity of the medium filled on one or more sides of the radiator.

[0093] Antenna system efficiency (total efficiency): It refers to the ratio of the input power to the output power at the port of the antenna.

[0094] Antenna radiation efficiency: It refers to the ratio of the power radiated by the antenna into space (i.e., the power effectively converted into electromagnetic waves) to the active power input to the antenna. Among them, the active power input to the antenna = the input power of the antenna - the loss power; the loss power mainly includes the return loss power, the ohmic loss power of the metal, and / or the dielectric loss power. The radiation efficiency is a value that measures the radiation ability of the antenna, and both metal loss and dielectric loss are factors affecting the radiation efficiency.

[0095] Those skilled in the art can understand that efficiency is generally expressed as a percentage, and there is a corresponding conversion relationship between it and dB. The closer the efficiency is to 0 dB, the better the efficiency of the antenna is characterized.

[0096] Antenna return loss: It can be understood as the ratio of the signal power reflected back to the antenna port through the antenna circuit to the transmitted power of the antenna port. The smaller the reflected signal, the larger the signal radiated into space through the antenna, and the greater the radiation efficiency of the antenna. The larger the reflected signal, the smaller the signal radiated into space through the antenna, and the smaller the radiation efficiency of the antenna.

[0097] The antenna return loss can be represented by the S11 parameter, and S11 belongs to one of the S parameters. S11 represents the reflection coefficient, and this parameter can characterize the pros and cons of the antenna transmission efficiency. The S11 parameter is usually negative. The smaller the S11 parameter, the smaller the antenna return loss, the smaller the energy reflected back by the antenna itself, that is, it means that the more energy actually enters the antenna, and the higher the system efficiency of the antenna; the larger the S11 parameter, the larger the antenna return loss, and the lower the system efficiency of the antenna.

[0098] It should be noted that in engineering, generally, the S11 value of -6 dB is used as a standard. When the S11 value of the antenna is less than -6 dB, it can be considered that the antenna can work normally, or it can be considered that the transmission efficiency of the antenna is good.

[0099] Antenna pattern: Also known as the radiation pattern. It refers to the graph of the relative field strength (normalized modulus value) of the antenna radiation field changing with direction at a certain distance (far field) from the antenna, and is usually represented by two mutually perpendicular plane patterns passing through the maximum radiation direction of the antenna.

[0100] The antenna pattern usually has multiple radiation beams. Among them, the radiation beam with the largest radiation intensity is called the main lobe, and the rest of the radiation beams are called side lobes or minor lobes. Among the side lobes, the side lobe in the direction opposite to the main lobe is also called the back lobe.

[0101] Directivity: Also known as the directivity of an antenna. It refers to the ratio of the maximum power density to the average value on the antenna pattern at a certain distance (far field) from the antenna, which is a dimensionless ratio greater than or equal to 1. It can be used to indicate the energy radiation characteristics of the antenna. The larger the directivity coefficient, the more the energy radiated by the antenna in a certain direction accounts for, and the more concentrated the energy radiation is.

[0102] Antenna gain: Used to characterize the degree to which the antenna concentrates and radiates the input power. Generally, the narrower the main lobe and the smaller the side lobes of the antenna pattern, the higher the antenna gain.

[0103] Polarization direction of the antenna: At a given point in space, the electric field strength E (vector) is a function of time t. As time goes by, the end point of the vector periodically depicts a trajectory in space. If the trajectory is a straight line and perpendicular to the ground, it is called vertical polarization; if it is horizontal to the ground, it is called horizontal polarization. If the trajectory is an ellipse or a circle and rotates in the right-hand or clockwise direction when observed along the propagation direction with time, it is called right-hand circular polarization (RHCP); if it rotates in the left-hand or counterclockwise direction with time, it is called left-hand circular polarization (LHCP).

[0104] Ground (GND): It can generally refer to at least a part of any ground layer, ground plane, or ground metal layer in an electronic device (such as a mobile phone), or at least a part of any combination of the above-mentioned ground layers, ground planes, or ground components. "Ground" can be used for grounding components in an electronic device. In one embodiment, "ground" can be the ground layer of the circuit board of the electronic device, or the ground plane formed by the middle frame of the electronic device or the ground metal layer formed by the metal film under the screen. In one embodiment, the circuit board can be a printed circuit board (PCB), such as an 8-layer, 10-layer, or 12 - 14-layer board with 8, 10, 12, 13, or 14 layers of conductive materials, or components separated and electrically insulated by dielectric layers or insulating layers such as fiberglass, polymers, etc. In one embodiment, the circuit board includes a dielectric substrate, a ground layer, and a trace layer, and the trace layer and the ground layer are electrically connected through vias. In one embodiment, components such as a display, a touch screen, input buttons, a transmitter, a processor, a memory, a battery, a charging circuit, a system on chip (SoC) structure, etc. can be mounted on the circuit board or connected to the circuit board; or electrically connected to the trace layer and / or the ground layer in the circuit board. For example, a radio frequency source is arranged on the trace layer.

[0105] Any of the above-mentioned ground layers, or ground plates, or ground metal layers is made of a conductive material. In one embodiment, the conductive material can be any one of the following materials: copper, aluminum, stainless steel, brass and their alloys, copper foil on an insulating substrate, aluminum foil on an insulating substrate, gold foil on an insulating substrate, silver-plated copper, silver-plated copper foil on an insulating substrate, silver foil on an insulating substrate, and tin-plated copper, cloth impregnated with graphite powder, a substrate coated with graphite, a copper-plated substrate, a brass-plated substrate, and an aluminum-plated substrate. Those skilled in the art can understand that the ground layer / ground plate / ground metal layer can also be made of other conductive materials.

[0106] Grounding: It means coupling with the above-mentioned ground / floor in any way. In one embodiment, grounding can be achieved through physical grounding, for example, through some structural members of the middle frame to achieve physical grounding at specific positions on the frame (or called, physical ground). In one embodiment, grounding can be achieved through device grounding, for example, through devices such as capacitors / inductors / resistors connected in series or parallel for grounding (or called, device ground).

[0107] In the embodiments of the present application, when it is mentioned within / between a certain numerical range, unless otherwise specified, the endpoint values of the range are included. For example, within the range of 2 to 10, the two endpoint values 2 and 10 are included.

[0108] Next, it will be combined with Figures 1a to 1d to introduce two antenna modes involved in the present application. Among them, Figure 1a is the structure of the common mode of an antenna 91 provided by the present application. Figure 1b is Figure 1a the schematic diagram of the current and electric field distributions corresponding to the common mode of the antenna 91 shown. Figure 1c is the structure of the differential mode of another antenna 92 provided by the present application. Figure 1d is Figure 1c the schematic diagram of the current and electric field distributions corresponding to the differential mode of the antenna 92 shown. Figures 1a to 1d The two ends of the antenna radiator in

[0109] are open, and its common mode and differential mode can be respectively called the wire common mode and the wire differential mode.

[0110] 1. Wire common mode (CM)

[0111] Figure 1aThe radiating element of antenna 91 is open at both ends and is connected to a feeding circuit (not shown in the figure) at the middle position 911. In one embodiment, the feeding form of antenna 91 adopts symmetrical feed. The feeding circuit can be connected to the middle position 911 of antenna 91 through the feeding wire 912. It should be understood that symmetrical feed can be understood as one end of the feeding circuit is connected to the radiating element, and the other end is coupled to the ground through the floor. Among them, the connection point (feeding point) of the feeding circuit and the radiating element is located at the center of the radiating element. The center of the radiating element can be, for example, the midpoint of the geometric structure, or the midpoint of the electrical length (or the area within a certain range near the above midpoint).

[0112] The middle position 911 of antenna 91 can be, for example, the geometric center of the antenna, or the midpoint of the electrical length of the radiating element. For example, the connection position of the feeding wire 912 and antenna 91 covers the middle position 911.

[0113] Figure 1b The current and electric field distributions of antenna 91 are shown. As Figure 1b shown, the current shows a reverse distribution on both sides of the middle position 911, for example, a symmetrical distribution; the electric field shows a same-direction distribution on both sides of the middle position 911. As Figure 1b shown, the current at the feeding wire 912 shows a same-direction distribution. Based on the same-direction distribution of the current at the feeding wire 912, Figure 1a the feeding shown can be called line CM feeding. Based on the reverse distribution of the current on both sides of the connection position of the radiating element and the feeding wire 912, Figure 1b the antenna mode shown can be called line CM mode (also can be simply called CM mode. For example, for a wire antenna, the CM mode refers to the line CM mode). Figure 1b The current and electric field shown can be respectively called the current and electric field of the line CM mode.

[0114] The current is stronger at the middle position 911 of antenna 91 (the current maximum point is near the middle position 911 of antenna 91) and weaker at both ends of antenna 91, as Figure 1b shown. The electric field is weaker at the middle position 911 of antenna 91 and stronger at both ends of antenna 91.

[0115] 2. Line differential mode (DM)

[0116] As Figure 1cThe left and right ends of the two radiators of the antenna 92 are shown as open ends, and a feeding circuit is connected at the middle position 921. In one embodiment, the feeding form of the antenna 92 adopts anti-symmetrical feed. One end of the feeding circuit is connected to one of the radiators through a feeding wire 922, and the other end of the feeding circuit is connected to the other radiator through the feeding wire 922. The middle position 921 can be the geometric center of the antenna 92, or the gap formed between the radiators.

[0117] It should be understood that the "central anti-symmetrical feed" mentioned in this application can be understood as that the positive and negative poles of the feeding unit are respectively connected to two connection points near the above-mentioned midpoints of the radiator. In one embodiment, the signal amplitudes output by the positive and negative poles of the feeding unit are the same, and the phases are opposite, for example, the phase difference is 180°±10°.

[0118] Figure 1d The current and electric field distributions of the antenna 92 are shown. As Figure 1d shown, the current shows a co-directional distribution on both sides of the middle position 921 of the antenna 92, for example, an anti-symmetrical distribution; the electric field shows an anti-directional distribution on both sides of the middle position 921. As Figure 1d shown, the current at the feeding wire 922 shows an anti-directional distribution. Based on the anti-directional distribution of the current at the feeding wire 922, Figure 1c the feeding shown in Figure 1d can be called line DM feeding. Based on the co-directional distribution of the current on both sides of the connection between the radiator and the feeding wire 922, Figure 1d the antenna mode shown in Figure 1d can be called line DM mode (which can also be simply called DM mode. For example, for a wire antenna, the DM mode refers to the line DM mode).

[0119] In one embodiment, in the line DM mode, or the half-mode, the current is stronger at the middle position 921 of the antenna 92 (the current maximum point is near the middle position 921 of the antenna 92), and weaker at both ends of the antenna 92, as Figure 1d shown. The electric field is weaker at the middle position 921 of the antenna 92 and stronger at both ends of the wire antenna 92.

[0120] It should be understood that for an antenna radiator, it can be understood as a metal structural member that generates radiation, and the number can be one, as Figure 1a and Figure 1b shown, or it can also be two, as Figure 1c andFigure 1d As shown, it can be adjusted according to actual design or production requirements. For example, for the line CM mode, it can also be like Figure 1c and Figure 1d shown, two radiators are used. The two ends of the two radiators are arranged oppositely and spaced by a gap. At the ends close to each other, a symmetric feeding method is adopted. For example, the same feed source signal is fed into the two ends close to each other of the two radiators, and an effect similar to the antenna structure shown in Figure 1a and Figure 1b can also be obtained. Correspondingly, for the line DM mode, it can also be like Figure 1a and Figure 1b shown, one radiator is used. Two feeding points are arranged at the middle position of the radiator and an anti-symmetric feeding method is adopted. For example, signals with the same amplitude and opposite phases are fed into the two symmetric feeding points on the radiator respectively, and an effect similar to the antenna structure shown in Figure 1c and Figure 1d can also be obtained.

[0121] 3. Line CM - DM mode

[0122] The above Figure 1a and Figure 1b respectively show that when the two ends of the radiator are open, different feeding methods are used to generate the line CM mode and the line DM mode respectively.

[0123] When the feeding form of the antenna adopts asymmetric feeding (the feeding point deviates from the middle position of the radiator, including edge feeding or offset feeding), or the grounding point of the radiator (the coupling position with the floor) is asymmetric (the grounding point deviates from the middle position of the radiator), the antenna can generate the first resonance and the second resonance simultaneously, corresponding to the line CM mode and the line DM mode respectively. For example, the first resonance corresponds to the line CM mode, and the current and electric field distributions are as shown in Figure 1b . The second resonance corresponds to the line DM mode, and the current and electric field distributions are as shown in Figure 1d .

[0124] It can be understood that the specific implementation manners described herein are only used to explain the relevant invention and are not intended to limit the invention. Additionally, it should be noted that for the convenience of description, only the parts related to the invention are shown in the drawings. The technical solutions of the embodiments of the present application will be described below in conjunction with the drawings.

[0125] Figure 2a is a schematic structural diagram of the electronic device 1000 provided by the embodiment of the present application in some embodiments. Figure 2b is Figure 2a a schematic structural diagram of the electronic device 1000 shown in another perspective. Figure 2c is Figure 2aPartial exploded structural schematic diagram of the electronic device 1000 shown in some embodiments.

[0126] As Figures 2a to 2c shown, the electronic device 1000 can be an electronic device with a photographing function such as a mobile phone, a tablet computer, an e-reader, a laptop computer, a wearable device such as a watch, etc. Figure 2a The electronic device 1000 in the illustrated embodiment will be described by taking a mobile phone as an example. For ease of description, the thickness direction of the electronic device 1000 is defined as the Z-axis, the length direction of the electronic device 1000 is defined as the Y-axis, and the width direction of the electronic device 1000 is defined as the X-axis. It can be understood that the coordinate system of the electronic device 1000 can also be specifically set according to actual needs, and the present application does not limit this.

[0127] Exemplarily, the electronic device 1000 may include a screen 200 and a housing 300. It can be understood that Figures 2a to 2c only some components included in the electronic device 1000 are schematically shown, and the actual shapes, actual sizes, and actual structures of these components are not limited by Figures 2a to 2c this. In other embodiments, when the electronic device 1000 is a device in other forms, the electronic device 1000 may not include the screen 200 either. Among them, the screen 200 can be installed on the housing 300. Figure 2a And Figure 2b schematically shows a structure in which the screen 200 and the housing 300 enclose a substantially cuboid shape. The screen 200 can be used to display images, texts, etc. It should be understood that in the embodiments of the present application, when the user holds (usually vertically and facing the screen 200) the electronic device 1000, the orientation where the electronic device 1000 is located has a top, a bottom, a left side, and a right side. Among them, the top of the electronic device 1000 can face the sky. In the present embodiment, the arrangement direction of the top and the bottom can be parallel to the Y-axis direction. The arrangement direction of the left side and the right side can be parallel to the X-axis direction.

[0128] Exemplarily, the housing 300 can be used to support the screen 200 and related components of the electronic device 1000. The housing 300 may include a middle frame 310 (housing) and a rear cover 320 (rear cover). The rear cover 320 and the screen 200 can be installed on opposite sides of the middle frame 310. The arrangement direction of the rear cover 320 and the screen 200 can be parallel to the Z-axis direction. The rear cover 320 can be fixedly connected to the middle frame 310 by means of adhesion, welding, etc. At this time, the screen 200, the middle frame 310, and the rear cover 320 can jointly enclose the internal space of the electronic device 1000. The internal space of the electronic device 1000 can be used to place the internal components of the electronic device 1000, such as a battery, a speaker, a microphone, or a receiver, etc. Among them, the rear cover 320 can be a rear cover 320 made of a metal material, or a rear cover 320 made of a non-conductive material, such as a glass rear cover, a plastic rear cover, or other non-metal rear covers, or it can also be a rear cover 320 made of both conductive and non-conductive materials.

[0129] Exemplarily, the middle frame 310 can include a frame 311 and a middle plate 312. The frame 311 can be arranged around the middle plate 312 and connected to the middle plate 312. The frame 311 can be formed of a conductive material such as metal. At this time, the frame 311 is a metal frame. In some embodiments, the middle frame 310 can also only include the frame 311. The rear cover 320 can be an integrally formed structure with the frame 311, that is, the rear cover 320 and the frame 311 are a whole.

[0130] As Figure 2c shown, the electronic device 1000 can also include a circuit board 400. The circuit board 400 can be a printed circuit board (PCB). The circuit board 400 can be located between the middle frame 310 and the rear cover 320. Electronic components, such as radio frequency chips, etc., can be carried on the circuit board 400. Among them, the circuit board 400 can use a flame-retardant material (FR-4) dielectric board, or a Rogers dielectric board, or a hybrid dielectric board of Rogers and FR-4, etc. It should be noted that FR-4 is a code for a flame-retardant material grade, and the Rogers dielectric board is a high-frequency board. In some embodiments, the circuit board 400 can also be located between the screen 200 and the middle frame 310. The present application does not limit the specific position of the circuit board 400.

[0131] In some embodiments, a metal layer can also be provided on the circuit board 400. The metal layer can be used for the electronic components carried on the circuit board 400 to be grounded, or for other components in the electronic device 1000 to be grounded (such as a bracket antenna, a frame antenna, etc.). At this time, the metal layer can be called a floor, or a ground plane, or a ground layer. Exemplarily, the edge of the circuit board 400 can be regarded as the edge of its floor.

[0132] In some embodiments, the conductive portions in the middle frame 310 and / or the rear cover 320 can also serve as the reference ground of the electronic device 1000. Devices such as the circuit board in the electronic device 1000 can be grounded by being electrically connected to the middle frame 310 and / or the rear cover 320. In other embodiments, the electronic device 1000 can also have other ground planes, which will not be elaborated here.

[0133] Figure 3 is Figure 2c A schematic structural diagram of the frame 311 of the electronic device 1000 shown.

[0134] As Figure 3 shown, the frame 311 of the electronic device 1000 can be a metal frame. The frame 311 can include a first short side 3111 and a second short side 3112 that are oppositely arranged, and a first long side 3113 and a second long side 3114 that are oppositely arranged. Both the first short side 3111 and the second short side 3112 can be connected between the first long side 3113 and the second long side 3114. An angle (such as a 90° angle) can be formed between the first long side 3113 and the first short side 3111. The length of the first long side 3113 can be greater than the length of the first short side 3111. It should be understood that the length of the first long side 3113 refers to the dimension of the first long side 3113 in its extending direction. The length of the first short side 3111 refers to the dimension of the first short side 3111 in its extending direction. In some embodiments, the first long side 3113, the second long side 3114, the first short side 3111, and the second short side 3112 can all be strip-shaped. The frame 311 can also include a plurality of corner portions (not shown in the figure). Any two adjacent ones of the first long side 3113, the second long side 3114, the first short side 3111, and the second short side 3112 can be transitionally connected through a corner portion. In some other embodiments, any one of the corner portions in the frame 311 can also be regarded as a part of the long side or the short side adjacent to the corner portion.

[0135] In the present embodiment, when the user holds the electronic device 1000 (please refer to Figure 2a ), the first short side 3111 can be located at the top of the electronic device 1000. The second short side 3112 can be located at the bottom of the electronic device 1000. The first long side 3113 can be located at the left side of the electronic device 1000. The second long side 3114 can be located at the right side of the electronic device 1000.

[0136] It should be noted that Figure 3The illustrated frame 311 is described by taking the non-foldable electronic device 1000 as an example. When the electronic device 1000 is a foldable electronic device 1000 (such as a multi-fold device with two folds or three folds, etc.), the above-mentioned first long side 3113, second long side 3114, first short side 3111, and second short side 3112 can be correspondingly understood as the long side and short side on the middle frame of the part corresponding to one of the folds in the multi-fold.

[0137] Figure 4 is Figure 3 A partial enlarged structural schematic diagram of the illustrated structure.

[0138] As Figure 4 shown, the electronic device 1000 may include an antenna device 500. The antenna device 500 may include at least one radiator. The antenna device 500 may use the conductive part of the frame 311 of the electronic device 1000 as the main radiator and / or parasitic stub. In one embodiment, the outer surface of the frame 311 may be a conductive material, such as a metal material, so as to form the appearance of a metal frame, which is suitable for metal industrial design (ID). In these embodiments, the conductive part of the frame 311 (for example, including the outer surface of the frame 311) may be used as the radiator of the antenna device 500.

[0139] In one embodiment, the outer surface of the frame 311 may be a non-conductive material, such as plastic, to form the appearance of a non-metal frame, which is suitable for non-metal ID. The inner surface of the frame 311 may include a conductive material, such as a metal material. In these embodiments, the conductive part of the frame 311 (for example, including the inner surface of the frame 311) may be used as the radiator of the antenna device 500. It should be understood that the radiator disposed on the inner surface of the frame 311 (or rather, the conductive material on the inner surface) is disposed in conformity with the non-conductive material of the frame 311 to minimize the volume occupied by the radiator and be closer to the outside of the electronic device 1000 to achieve a better signal transmission effect. It should be noted that the antenna radiator disposed in conformity with the non-conductive material of the frame 11 means that the antenna radiator may be disposed closely against the inner surface of the non-conductive material, or may be embedded inside the non-conductive material, or may be disposed close to the inner surface of the non-conductive material. For example, there may be a certain small gap between the antenna radiator and the inner surface of the non-conductive material. It should be understood that both the conductive material and the non-conductive material can be regarded as part of the frame 11. Disposing the antenna radiator in conformity with the non-conductive material of the frame 11 can also be called a frame radiator.

[0140] Exemplarily, the first short side 3111 may be provided with a first slot 311a and a second slot 311b. The first slot 311a and the second slot 311b may divide a metal segment on the first short side 3111 to form a first frame radiator 510 of the antenna device 500. The first slot 311a and the second slot 311b may be filled with an insulating material. For example, the insulating material may be a polymer, glass, ceramic or a combination of these materials. In other embodiments, the material of the first short side 3111 may also be a non-conductive material. At this time, the first short side 3111 may not be provided with the first slot 311a and the second slot 311b. The first frame radiator 510 may be a conductive body mounted on the first short side 3111, such as an FPC antenna or an LDS antenna radiator. In some embodiments, the width of the first slot 311a / second slot 311b may be in the range of 0.1 mm to 2 mm. It should be understood that in the embodiments of the present application, the width of the slots opened on the frame 311 may be within the above range. In some other embodiments, the first frame radiator 510 may also be provided on the first long side 3113. The present application does not strictly limit the specific position and form of the first frame radiator 510.

[0141] Exemplarily, the first frame radiator 510 may include a first end 511 located at the first slot 311a and a second end 512 located at the second slot 311b. Both the first end 511 and the second end 512 may be open ends. That is, the first end 511 may form a first open end of the first frame radiator 510, and the second end 512 may form a second open end of the first frame radiator 510. In other embodiments, the first end 511 may be an open end and the second end 512 may be a ground end.

[0142] Exemplarily, the first frame radiator 510 may include a first feeding point 514. The antenna device 500 may further include a feed source 520. The feed source 520 may be electrically connected to the first feeding point 514. The feed source 520 may input an electrical signal to the first feeding point 514 to excite the first frame radiator 510 to generate resonance.

[0143] Exemplarily, the first frame radiator 510 may include a first grounding point 513. The first frame radiator 510 may be coupled to the ground at the first grounding point 513. Wherein, the ground may be a metal layer on the circuit board 400 and / or the middle frame 310 (please refer to Figure 2c shown). It should be understood that in the embodiments of the present application, the coupling connection is only illustrated by electrical connection. In actual production or practice, it may also be realized by an indirect coupling method. For the sake of brevity of discussion, it will not be elaborated one by one. In other embodiments, the first frame radiator 510 may not include the first grounding point 513. Figure 4Only the case where the first frame radiator 510 includes the first grounding point 513 is schematically shown.

[0144] Exemplarily, the antenna device 500 can be used to receive or transmit signals in the communication frequency band for satellite messages and / or satellite phones. The operating frequency band of the antenna device 500 can include the satellite communication frequency band. Satellite communication includes at least one communication service among satellite receiving and / or sending short messages (also known as short text messages), satellite calling and / or answering calls, and satellite data (such as surfing the Internet). That is to say, the first frame radiator 510 can be used to receive / transmit signals in the satellite communication frequency band. At this time, the first short side 3111 can be regarded as the top side of the electronic device 1000. The second short side 3112 can be regarded as the bottom side of the electronic device 1000. The first long side 3113 can be regarded as the first side of the electronic device 1000. The second long side 3114 can be regarded as the second side of the electronic device 1000. In other embodiments, the first frame radiator 510 can also be located on the first long side 3113. At this time, the first long side 3113 can be regarded as the top side of the electronic device 1000. The first short side 3111 and the second short side 3112 can be regarded as the first side and the second side of the electronic device 1000 respectively. In other words, the side where the satellite antenna radiator (i.e., the first frame radiator 510 in this embodiment) is located can be regarded as the top side of the electronic device 1000.

[0145] In one embodiment, the satellite communication frequency band may include some frequency bands in the Tiantong satellite system. For example, it may include the transmitting frequency band (1980 MHz - 2010 MHz) and the receiving frequency band (2170 MHz - 2200 MHz) in the Tiantong satellite system. In one embodiment, the satellite communication frequency band may include some frequency bands in the Beidou satellite system. For example, it may include the transmitting frequency band (1610 MHz - 1626.5 MHz) and the receiving frequency band (2483.5 MHz - 2500 MHz) in the Beidou satellite system. In one embodiment, the antenna device 500 may be a low-earth orbit satellite communication antenna. For example, the transmitting frequency band of the low-earth orbit satellite communication antenna is 1668 MHz - 1675 MHz, and the receiving frequency band of the low-earth orbit satellite communication antenna is 1518 MHz - 1525 MHz. Alternatively, the antenna device 500 may be a Beidou satellite communication antenna. For example, the transmitting frequency band of the Beidou satellite communication antenna is 1615 MHz - 1620 MHz, and the receiving frequency band of the Beidou satellite communication antenna is 2480 MHz - 2500 MHz. Alternatively, the antenna device 500 may be a Tiantong satellite communication antenna or a geostationary orbit satellite communication antenna. For example, the transmitting frequency band of the Tiantong satellite communication antenna is 1980 MHz - 2000 MHz, and the receiving frequency band of the Tiantong satellite communication antenna is 2170 MHz - 2200 MHz. Alternatively, the antenna device 500 may also be a medium-earth orbit satellite communication antenna with a working frequency band of 4 GHz - 6 GHz. In other embodiments, the antenna device 500 may also be applied to other satellite communication systems, and the embodiments of the present application do not limit this.

[0146] Exemplarily, when the antenna device 500 operates in the Tiantong satellite system (i.e., the working frequency band of the antenna includes at least some frequency bands in the Tiantong satellite system), the electronic device 1000 can perform voice communication through the antenna. In some embodiments, when the antenna device 500 operates in the Beidou satellite system (i.e., the working frequency band of the antenna includes at least some frequency bands in the Beidou satellite system), the electronic device 1000 can send or receive short messages through the antenna device 500.

[0147] Figure 5 is Figure 2b The exploded structural schematic diagram of the camera decoration assembly 100 in some embodiments shown. Figure 6 is Figure 2a The assembled structural schematic diagram of the camera decoration assembly 100, the frame 311, and the circuit board 400 of the electronic device 1000 in some embodiments shown. Figure 7 is Figure 2b The partial cross-sectional structural schematic diagram of a certain embodiment of the electronic device 1000 cut along A - A. For ease of understanding, Figure 6 the protective cover 20 of the camera decoration assembly 100 is hidden in the figure.

[0148] As shown Figures 5 to 7 in the figure, the electronic device 1000 may further include a camera decoration component 100 and a camera module 600( Figure 3 is also shown for the camera decoration component 100 and the camera module 600). The rear cover 320 may be provided with a light-transmitting hole 321. The camera module 600 may be installed on a side of the middle frame 310 facing away from the screen 200. The light incident hole of the camera module 600 may be exposed relative to the light-transmitting hole 321 of the rear cover 320. The camera decoration component 100 may be fixed to the rear cover 320. At least a part of the camera decoration component 100 may cover the light-transmitting hole 321. In the present embodiment, the camera decoration component 100 may be located at an intermediate position between the first side (which is also the first long side 3113 in the present embodiment) and the second side (which is also the second long side 3114 in the present embodiment), and is disposed close to the top side (which is also the first short side 3111 in the present embodiment). That is, the camera decoration component 100 may be located at the upper-middle position of the rear cover 320 (please refer to Figure 2b as shown). In other embodiments, the camera decoration component 100 may be disposed closer to the second side relative to the first side.

[0149] Exemplarily, the camera decoration component 100 may include a decoration body 10 and a protection cover plate 20. The decoration body 10 may be generally in a sheet or plate shape. The decoration body 10 may be fixedly connected to the rear cover 320. The decoration body 10 may be spaced apart from the middle plate 312 of the middle frame 310 and the circuit board 400. At least a part of the decoration body 10 may cover the avoidance hole of the rear cover 320. Among them, the decoration body 10 may be disposed facing the circuit board 400 and / or the middle plate 312 of the middle frame 310. In the present embodiment, the decoration body 10 may be disposed facing the circuit board 400.

[0150] Exemplarily, the decoration body 10 may be provided with an avoidance hole 10a. The avoidance hole 10a may be disposed opposite to the light incident hole of the camera module 600. Exemplarily, the number of the camera modules 600 may be multiple. The number of the avoidance holes 10a may also be multiple. The multiple avoidance holes 10a may be disposed opposite to the light incident holes of the multiple camera modules 600 one by one. Among them, the shapes and sizes of the multiple avoidance holes 10a may be exactly the same. In this way, it is beneficial to improve the appearance consistency of the electronic device 1000 and improve the appearance effect of the electronic device 1000. In some embodiments, the shapes and sizes of the multiple avoidance holes 10a may not be completely the same.

[0151] Exemplarily, the protection cover plate 20 may be located on a side of the decoration body 10 facing away from the middle frame 310, and is fixedly connected to the decoration body 10 and / or the rear cover 320. The material of the protection cover plate 20 may be a material that can transmit light, such as glass or transparent plastic.

[0152] Exemplarily, the decorative member body 10 may include a metal part. Among them, the first radiator 30 may be formed by at least a part of the metal part. In this embodiment, all of the metal part of the decorative member body 10 may be used to form the first radiator 30. In some embodiments, the decorative member body 10 may further include a non-metal part. The non-metal part may be connected to the metal part. In some embodiments, a dielectric may also be filled between the decorative member body 10 and the middle frame 310 and / or the circuit board 400 to isolate the first radiator 30 from the middle frame 310 and / or the circuit board 400. Among them, the material of the dielectric may be an insulating material such as plastic.

[0153] Figure 8 Yes Figure 6 It is a schematic diagram of the assembled structure of the structure shown in another perspective with the camera module 600. Figure 9 Yes Figure 2b It is a schematic diagram of a partial cross-sectional structure in an embodiment of the electronic device 1000 cut along B-B.

[0154] As Figures 7 to 9 As shown, the decorative member body 10 may be located at an intermediate position between the first side (which is also the first long side 3113 in this embodiment) and the second side (which is also the second long side 3114 in this embodiment), that is, the decorative member body 10 may be centered in the length extension direction of the top side (which is also the first short side 3111 in this embodiment). Among them, the distance between the first radiator 30, the decorative member body 10 and the first side is the first distance. The distance between the decorative member body 10 and the second side is the second distance. Exemplarily, when the ratio of the first distance to the second distance is within the range of 0.8 to 1.2, it can be regarded that the decorative member body 10 is located at the intermediate position between the first side and the second side. It should be noted that the ratio of the first distance to the second distance within the range of 0.8 to 1.2 includes the two end values of 0.8 and 1.2.

[0155] Exemplarily, the first radiator 30 may include a connected first region 31 and a second region 32. The projection of the first region 31 of the first radiator 30 on the circuit board 400 may not overlap with the projection of the camera module 600 on the circuit board 400. The projection of the second region 32 of the first radiator 30 on the circuit board 400 may overlap with the projection of the camera module 600 on the circuit board 400. For ease of understanding, Figure 8 The outline of a part of the camera module 600 blocked by the first radiator 30 is schematically shown by a relatively wide dashed line in the figure.

[0156] Exemplarily, the first radiator 30 may include a plurality of first grounding points 33 arranged at intervals. The plurality of first grounding points 33 may all be located in the first region 31. The camera decoration component 100 may further include a plurality of first grounding members 61 ( Figure 8 the first grounding member 61 is schematically shown by a narrower dotted line in Figure 8 ). The first radiator 30 may be coupled to the floor through the plurality of first grounding members 61 at the plurality of first grounding points 33 in a one-to-one correspondence. In the present embodiment, the floor may be a metal layer on the circuit board 400. In some embodiments, at least one of the plurality of first grounding points 33 may also be used to release static electricity generated on the decoration body 10. In some embodiments, the resonant frequency and radiation pattern of the first radiator 30 may also be adjusted by adjusting the relative positions between the plurality of first grounding points 33.

[0157] Exemplarily, the first radiator 30 may include a first feeding point 34. The camera decoration component 100 may further include a first feeder 71 ( Figure 8 the first feeder 71 is schematically shown by a narrower dotted line in Figure 8 ). The first feeding point 34 may be located in the first region 31. The first radiator 30 may be electrically connected to a first feeding end (not shown in the figure) of the circuit board 400 through the first feeder 71 at the first feeding point 34.

[0158] Exemplarily, the first frame radiator 510 of the electronic device 1000 may be used to operate in a first frequency band. The first radiator 30 may be used to support communication in the first frequency band, that is, the first frame radiator 510 and the first radiator 30 have the same frequency. The first frame radiator 510 and the first radiator 30 may be electrically connected to the same radio frequency chip (not shown in the figure). That is, the antenna device 500 may be electrically connected to the same radio frequency chip through the first frame radiator 510 and the first radiator 30, so as to expand the radiation pattern, or expand the beam, or expand the bandwidth, thereby improving the antenna performance. It should be understood that the same radio frequency chip in the embodiments of the present application may refer to the same receiver, or the same transceiver. In this way, the first frame radiator 510 and the first radiator 30 may be used as receiving antennas with the same function, and diversity synthesis may be performed through the receiver or transceiver to improve the antenna performance. Among them, the first frequency band may correspond to the communication frequency band of satellite messages and / or satellite phones, for example, the receiving frequency band of satellite messages and / or satellite phones. At this time, the first radiator 30 and the first frame radiator 510 may be electrically connected to the same satellite communication chip / radio frequency chip.

[0159] Figure 10 is a schematic diagram of the maximum radiation direction of the radiation pattern generated by the first frame radiator 510 of the general electronic device 1000 alone. Figure 11 is Figure 6Schematic diagram of the maximum radiation direction of the radiation pattern jointly generated by the first frame radiator 510 and the first radiator 30 of the electronic device 1000 shown.

[0160] As Figure 10 and Figure 11 shown, the maximum radiation direction of the radiation pattern generated by the first frame radiator of a general electronic device can be the direction from the bottom to the top of the electronic device. The first frame radiator can be used to operate in the first frequency band. When the first frame radiator radiates, the beam generated by the first frame radiator is narrow (for example, below ±10°). In this embodiment, by setting the first radiator 30 in the camera decoration component 100, the first radiator 30 can be used to support communication in the first frequency band. The first radiator 30 and the first frame radiator 510 are of the same frequency. The first radiator 30 and the first frame radiator 510 can be electrically connected to the same radio frequency chip. In this way, the first radiator 30 and the first frame radiator 510 can be used as receiving antennas with the same function and perform diversity synthesis through the same radio frequency chip. When the first radiator 30 and the first frame radiator 510 work simultaneously, the radiation pattern generated by the first radiator 30 can be complementary to the radiation pattern generated by the first frame radiator 510, and the beam jointly generated by the first radiator 30 and the first frame radiator 510 is wide (for example, above ±30°) to improve the antenna performance.

[0161] Exemplarily, the first frequency band can be applied to the communication frequency band of satellite messages and / or satellite phones. For example, the first frequency band can correspond to the receiving frequency band of satellite messages and / or satellite phones. That is, both the first radiator 30 and the first frame radiator 510 can be used to receive signals in the first frequency band. In some embodiments, the first frame radiator 510 can also operate in the transmitting frequency band of satellite messages and / or satellite phones. That is, the first frame radiator 510 can be used to receive and transmit signals in the first frequency band. The first radiator 30 can only be used to receive signals in the first frequency band. In other embodiments, the first frequency band can also correspond to the receiving frequency band of satellite messages and / or satellite phones. That is, both the first radiator 30 and the first frame radiator 510 can be used to transmit signals in the first frequency band. In some other embodiments, both the first radiator 30 and the first frame radiator 510 can also be used to receive and transmit signals in the first frequency band.

[0162] It can be understood that the camera decoration component 100 in this embodiment may include a decoration body 10. Among them, the decoration body 10 may include a metal part. At least part of the metal part may be used to form a first radiator 30. The first radiator 30 may be used to support the communication of the first frame radiator 510 in the first frequency band. That is, the first radiator 30 may have the same frequency as the first frame radiator 510. The first radiator 30 and the first frame radiator 510 are electrically connected to the same radio frequency chip. In this way, the first radiator 30 and the first frame radiator 510 can perform diversity synthesis through the same radio frequency chip to improve the antenna performance. At the same time, the first radiator 30 is formed by at least part of the metal part of the decoration body 10. The metal part of the decoration body 10 can achieve "one thing with multiple uses", so that the first radiator 30 can improve the antenna performance on the basis of not occupying the limited antenna layout space in the frame 311 of the electronic device 1000, which is beneficial to relieve the antenna layout pressure of the frame 311 of the electronic device 1000.

[0163] Secondly, the first frame radiator 510 may be disposed on the top edge, and the decoration body 10 may be centered relative to the first side edge and the second side edge. The radiation pattern of the first radiator 30 may be complementary to the radiation pattern of the first frame radiator 510. The first radiator 30 and the first frame radiator 510 may be combined into a wide beam to expand the radiation pattern and the beam, so that the radiation jointly formed by the first radiator 30 and the first frame radiator 510 can have good transmission and reception capabilities in a relatively wide direction.

[0164] Secondly, the first frequency band can be applied to the communication frequency band of satellite messages and / or satellite phones. It should be understood that when a user conducts satellite communication, the maximum radiation direction of the antenna needs to be pointed at the satellite to establish communication with the satellite (i.e., establish a communication connection with the satellite). When the beam of the antenna is narrow (e.g., below ±10°), the requirement for pointing at the satellite by the antenna is high, and the attitude change of the electronic device 1000 has a greater impact on the satellite communication quality. When the beam of the antenna is wide (e.g., above ±30°), the requirement for pointing at the satellite is low, and the attitude change of the electronic device 1000 has a smaller impact on the satellite communication quality. In this embodiment, the first radiator 30 can be combined with the first frame radiator 510 to form a wide beam, which is beneficial to reducing the requirement for pointing at the satellite during satellite communication by the electronic device 1000. Thus, the impact of the attitude change of the electronic device 1000 on the satellite communication quality can be effectively reduced, which is beneficial to improving the satellite communication performance of the electronic device 1000. Among them, the first frequency band can correspond to the receiving frequency band of satellite messages and / or satellite phones. In this way, when the user uses the electronic device 1000 to receive satellite signals, the receiving sensitivity is high, which is beneficial to enhancing the signal receiving ability of the electronic device 1000 and improving the user experience. In other words, the first radiator 30 in this embodiment can form a multi-satellite antenna system with the first frame radiator 510. In this way, by setting up the multi-satellite antenna system, the experience of the user using the electronic device 1000 for satellite communication can be effectively improved.

[0165] In some embodiments, the first radiator 30 may not include the first feeding point 34. The first radiator 30 can also act as a parasitic stub of the antenna device 500 to generate resonance and improve the antenna performance of the antenna device 500.

[0166] In some embodiments, the camera decoration component 100 can be disposed relatively close to the first long side 3113 along the second long side 3114. The first frame radiator 510 can also be disposed on the first long side 3113. Among them, the first frequency band of the first frame radiator 510 can correspond to the communication frequency band of WI FI / Bluetooth. In this way, the first radiator 30 can be used to enhance the communication signals of WI FI / Bluetooth of the electronic device 1000 and improve the user experience.

[0167] Please refer to again Figures 5 to 7, the camera decoration component 100 may further include a second radiator 40. The second radiator 40 may be an NFC coil. The second radiator 40 may be fixed to the surface of the first radiator 30 facing away from the screen 200 by means of adhesion or the like. The second radiator 40 may be located between the decorative member body 10 and the protective cover plate 20. The second radiator 40 may be spaced apart from the first feeding point 34 and the plurality of first grounding points 33 of the first radiator 30. The second radiator 40 may also be spaced apart from the plurality of avoidance holes 10a of the decorative member body 10. Wherein, the operating frequency band of the second radiator 40 may be 13.5 MHz. The operating frequency band of the second radiator 40 may be much lower than the first frequency band. For example, the center frequency of the first frequency band may be greater than 100 times the center frequency of the operating frequency band of the second radiator 40. In other embodiments, the second radiator 40 may also be a wireless charging coil.

[0168] Exemplarily, the second radiator 40 may include a second feeding point 41. The second feeding point 41 may be electrically connected to a second feeding end (not shown in the figure) on the circuit board 400 at the second feeding point 41. Wherein, the second radiator 40 may be electrically connected to the second feeding end on the circuit board 400 through an electrical connector such as a lead wire around the decorative member body 10 at the second feeding point 41. In other embodiments, the decorative member body 10 may further be provided with a communication hole. The second radiator 40 may also be electrically connected to the second feeding end on the circuit board 400 through an electrical connector such as a lead wire passing through the communication hole on the decorative member body 10 at the second feeding point 41.

[0169] Exemplarily, the camera decoration component 100 may further include an inductance structure (not shown in the figure). The inductance structure may be connected in series with the second feeding point 41 of the second radiator 40. Wherein, the inductance structure may include one or more inductors. Exemplarily, the inductance of the inductance structure may be greater than 60 mH. Thus, by connecting the inductance structure in series with the second feeding point 41, the inductance structure can act as a low-pass filter to cut off the high-frequency signal input to the second radiator 40 and avoid the influence of clutter.

[0170] Exemplarily, the camera decoration component 100 may further include an isolation layer (not shown in the figure). The isolation layer may be fixed between the first radiator 30 and the second radiator 40. The material of the isolation layer may be ferrite or nanocrystalline. Thus, the isolation layer may exhibit the characteristics of a magnetic conductor at low frequencies (for example, at the operating frequency band of the second radiator 40), and the isolation layer may exhibit the characteristics of an electrical conductor with a low conductivity at high frequencies (for example, at the first frequency band), so as to avoid resonance between the second radiator 40 and the first radiator 30, and the isolation degree between the second radiator 40 and the first radiator 30 is relatively good.

[0171] It can be understood that the camera decoration component 100 in this embodiment may include a first radiator 30 and a second radiator 40. The first radiator 30 may be constituted by at least a metal part of the decoration part body 10. The second radiator 40 may be an NFC coil or a wireless charging coil. The second radiator 40 may be fixedly connected to the surface of the first radiator 30. In this way, the second radiator 40 can be disposed closely to the first radiator 30, and the two can share the space of the camera decoration component 100, so that on the basis of not occupying the limited antenna layout space in the frame 311 of the electronic device 1000, the antenna performance can be improved, which is beneficial to releasing the antenna layout pressure of the frame 311 of the electronic device 1000.

[0172] Figure 12 Yes Figure 6 The enlarged structural schematic diagram of the structure shown at C.

[0173] As Figure 9 And Figure 12 As shown, the camera decoration component 100 may further include a third radiator 50 ( Figure 5 And Figure 6 The third radiator 50 is also schematically shown in). The first radiator 30 may be provided with a groove 35. The third radiator 50 may be at least partially disposed in the groove 35. The third radiator 50 may be an LDS antenna radiator or an FPC antenna radiator. The camera decoration component 100 may further include a bracket (not shown in the figure). The third radiator 50 may be fixed in the groove 35 of the first radiator 30 through the bracket. The third radiator 50 may be suspended relative to the bottom wall 351 of the groove 35. Among them, the bracket may be an insulator for carrying the third radiator 50. For example, the bracket may be a plastic bracket. The third radiator 50 may be disposed (for example, printed) on the upper surface or the lower surface of the bracket. Exemplarily, the height of the third radiator 50 may be less than or equal to the depth of the groove 35. Among them, the height of the third radiator 50 may be the distance between the upper surface of the third radiator 50 (that is, the surface of the third radiator 50 facing the opening of the groove 35) and the bottom wall 351 of the groove 35.

[0174] Exemplarily, the third radiator 50 may be a sheet radiator. In one embodiment, the length of the third radiator 50 may be less than 5 times the width of the third radiator 50. That is, the ratio of the length to the width of the third radiator 50 may be less than 5. In one embodiment, when the shape of the third radiator 50 is an irregular shape, the length and width of the third radiator 50 may be the length and width of the rectangle formed by the outer contour of the third radiator 50. At this time, the ratio of the area of the third radiator 50 itself to the area of the rectangle formed by the outer contour of the third radiator 50 may be greater than 1. Wherein, for the convenience of description, the length direction of the third radiator 50 is defined as the first direction, and the width direction of the third radiator 50 is defined as the second direction. In this embodiment, the first direction may be parallel to the X-axis direction. The second direction may be parallel to the Y-axis direction.

[0175] Exemplarily, the third radiator 50 may include a first end 51 and a second end 52. The first end 51 of the third radiator 50 may be a part where a third grounding point 53 is provided on the third radiator 50, or in other words, a grounded part on the third radiator 50. The camera decoration assembly 100 may further include a second grounding member 72. The third radiator 50 may be electrically connected to the first radiator 30 through the second grounding member 72 at the third grounding point 53. At this time, the first radiator 30 may be used as the reference ground of the third radiator 50. It should be understood that since the size of the third radiator 50 is smaller than that of the first radiator 30, the fundamental mode frequency band of the third radiator 50 may be higher than that of the first radiator 30, so that the first radiator 30 can be regarded as the reference ground of the third radiator 50. The second end 52 of the third radiator 50 is not grounded. The first end 51 of the third radiator 50 may be a grounded end, and the second end 52 of the third radiator 50 may be an open end. The current of the third radiator 50 may flow into the first radiator 30 through the first grounding point 33. Exemplarily, the first end 51 and the second end 52 may be arranged in the first direction. The number of the third grounding points 53 may be multiple (for example, three). The multiple third grounding points 53 may be arranged at intervals along the second direction.

[0176] Exemplarily, the third radiator 50 may include a third feeding point 54. The third feeding point 54 may be located between two adjacent third grounding points 53. The bottom wall 351 of the groove 35 of the first radiator 30 may further be provided with a through hole 352. The camera decoration assembly 100 may further include a second feeder 62. The third radiator 50 may be electrically connected to the feeding point end of the circuit board 400 through the second feeder 62 at the third feeding point 54. Wherein, the second feeder 62 may pass through the through hole 352 of the first radiator 30.

[0177] In some embodiments, the camera decoration component 100 may further include a feeder grounding member 73. One end of the feeder grounding member 73 may be electrically connected to the first radiator 30, and the other end of the feeder grounding member 73 may be electrically connected to the floor. A part of the feeder grounding member 73 may be located within the through hole 352. In this way, the impedance of the third feeding point 54 of the third radiator 50 can be adjusted through the feeder grounding member 73, improving the antenna performance. In one embodiment, the feeder grounding member 73 may be a hollow structure. The second feeder 62 may be inserted into the feeder grounding member 73. The feeder grounding member 73 may wrap a part of the second feeder 62. The second feeder 62 and the feeder grounding member 73 may form a coaxial structure. At this time, the second feeder 62 may be equivalent to the inner core of the coaxial structure, and the feeder grounding member 73 may be equivalent to the outer core of the coaxial structure. In another embodiment, the feeder grounding member 73 may be a solid structure. The feeder grounding member 73 may be located on one side of the second feeder 62. Alternatively, the number of feeder grounding members 73 may also be two. The second feeder 62 may be located between the two feeder grounding members 73 and be spaced apart from the two feeder grounding members 73.

[0178] Figure 13 Yes Figure 6 Schematic diagram of the S11 simulation curves of the first radiator 30 and the third radiator 50 shown. It should be noted that Figure 13 In, curve 1 is the S11 simulation curve of the first radiator 30, and curve 2 is the S11 simulation curve of the third radiator 50.

[0179] As Figure 13 shown, the first radiator 30 may generate multiple resonances based on the fundamental mode and higher-order modes. Among them, the resonance generated by the first radiator 30 based on the fundamental mode is the first resonance. The first radiator 30 may operate in multiple resonance frequency bands. The third radiator 50 may generate one resonance based on the fundamental mode, that is, the second resonance. The frequency band of the first resonance may be lower than that of the second resonance.

[0180] It can be understood that the camera decoration component 100 in this embodiment may further include a third radiator 50, and the third radiator 50 may be at least partially disposed in the groove 35 of the first radiator 30. In this way, the first radiator 30 and the third radiator 50 can share the space of the camera decoration component 100, so that on the basis of not occupying the limited antenna layout space in the frame 311 of the electronic device 1000, the antenna performance can be improved, which is beneficial to releasing the antenna layout pressure of the frame 311 of the electronic device 1000.

[0181] Figure 14 Yes Figure 12 Schematic structural diagram of the camera decoration component 100 in another embodiment shown. Figure 15 Yes Figure 14Schematic diagram of the S11 simulation curves of the third radiator 50 and the fourth radiator 80 shown.

[0182] As Figure 14 and Figure 15 shown, the structure of the camera decoration component 100 in this embodiment is substantially the same as that of the camera decoration component 100 shown in Figure 12 and the same parts will not be described again. The differences between the two will be introduced below. Exemplarily, a third ground point 53 may be provided at the first end portion 51 of the third radiator 50. The camera decoration component 100 may further include a fourth radiator 80. The fourth radiator 80 may be an LDS antenna radiator or an FPC antenna radiator. The fourth radiator 80 may be fixed in the groove 35 of the first radiator 30 through a bracket and is arranged at an interval from the third radiator 50. The fourth radiator 80 may be at least partially received in the groove 35. The fourth radiator 80 may be suspended relative to the bottom wall 351 of the groove 35. Exemplarily, the fourth radiator 80 may be a sheet radiator. The shape and size of the fourth radiator 80 may be the same as those of the third radiator 50.

[0183] Exemplarily, the fourth radiator 80 may include a first end portion 81 and a second end portion 82. The first end portion 81 of the fourth radiator 80 may be the part where a fourth ground point 83 is provided on the fourth radiator 80, or in other words, the grounded part on the fourth radiator 80. The camera decoration component 100 may further include a third grounding member 74. The fourth radiator 80 may be electrically connected to the first radiator 30 through the third grounding member 74 at the fourth ground point 83. At this time, the first radiator 30 may also serve as the reference ground of the fourth radiator 80. The second end portion 82 of the fourth radiator 80 is not grounded. The first end portion 81 of the fourth radiator 80 is the grounded end, and the second end portion 82 of the fourth radiator 80 is the open end. Among them, the first end portion 81 of the fourth radiator 80 may be disposed opposite to the second end portion 52 of the third radiator 50. The second end portion 82 of the fourth radiator 80 may be disposed opposite to the first end portion 51 of the third radiator 50. That is to say, the grounded end of the fourth radiator 80 may be disposed opposite to the open end of the third radiator 50. The open end of the fourth radiator 80 may be disposed opposite to the grounded end of the third radiator 50.

[0184] Exemplarily, the fourth radiator 80 may generate relevant resonance by coupling the energy of the third radiator 50. At this time, the third radiator 50 and the fourth radiator 80 may form a composite antenna and operate in two consecutive resonance frequency bands to achieve wideband coverage. It should be understood that when the ratio between the two frequencies corresponding to the two resonance points is in the range of 1:1 to 1:1.2, the two resonance frequency bands where the two resonance points are located can be regarded as continuous. Among them, the third radiator 50 may be used as the main radiator. The fourth radiator 80 may be used as the parasitic radiator.

[0185] It can be understood that in this embodiment, a composite antenna is formed by arranging the fourth radiator 80 in the groove 35 and the third radiator 50. Among them, the third radiator 50 can be used as the main radiator, and the fourth radiator 80 can be used as the parasitic radiator. In this way, the composite antenna formed by the third radiator 50 and the fourth radiator 80 together can generate two resonant frequency bands, and the two resonant frequency bands are continuous, which is beneficial to broadening the bandwidth of the composite antenna and improving the antenna performance. At the same time, the fourth radiator 80 can reuse the space of the camera decoration component 100, so that on the basis of not occupying the limited antenna layout space in the frame 311 of the electronic device 1000, the antenna performance can be improved, which is beneficial to releasing the antenna layout pressure of the frame 311 of the electronic device 1000.

[0186] Figure 16 Yes Figure 12 It is a schematic structural diagram of the structure shown in another embodiment. Figure 17 Yes Figure 16 It is a schematic diagram of the S11 simulation curve of the third radiator 50 shown. It should be noted that Figure 17 In the curve 1 is the S11 simulation curve of the radiation generated by the first current on the third radiator 50, and the curve 2 is the S11 simulation curve of the radiation generated by the second current on the third radiator 50.

[0187] As Figure 16 And Figure 17 As shown, the structure of the camera decoration component 100 in this embodiment is substantially the same as that of the camera decoration component 100 shown in Figure 12 The same parts will not be described in detail. The differences between the two will be introduced below. Exemplarily, the third radiator 50 may further include a fourth feeding point 55. The third radiator 50 may include a third end 56 and a fourth end 57. The third end 56 and the fourth end 57 may be arranged in the second direction. The third feeding point 54 may be located at the first end 51 of the third radiator 50 and is disposed close to the third end 56. For example, the first third feeding point 54 may be located at the corner position between the first end 51 and the third end 56. The fourth feeding point 55 may be located at the first end 51 and is located between the third end 56 and the fourth end 57. For example, the fourth feeding point 55 may be located at the middle position between the third end 56 and the fourth end 57. That is, the distance from the fourth feeding point 55 to the third end 56 may be equal to the distance from the fourth feeding point 55 to the fourth end 57.

[0188] Exemplarily, the number of through holes 352 of the groove 35 can be two. The number of the second feeders 62 can also be two. One of the feeders 62 can pass through one of the through holes 352 and be respectively connected to the third feeding point 54 and the third feeding end of the circuit board 400 (not shown in the figure). The other feeder 62 can pass through the other through hole 352 and be respectively connected to the fourth feeding point 55 and the fourth feeding end of the circuit board 400 (please refer to Figure 9 as shown) (not shown in the figure).

[0189] Exemplarily, the number of the third grounding points 53 of the third radiator 50 can be two. One of the third grounding points 53 can be located between the third feeding point 54 and the fourth feeding point 55. The other third grounding point 53 can be located on the side of the fourth feeding point 55 facing away from the third feeding point 54.

[0190] Exemplarily, when the third radiator 50 operates, the third feeding point 54 can excite a first current in the first direction on the third radiator 50, and the fourth feeding point 55 can excite a second current in the second direction on the third radiator 50. The first current can be orthogonal to the second current. That is to say, the third feeding point 54 and the fourth feeding point 55 can respectively excite a transverse mode and a longitudinal mode on the third radiator 50. The third radiator 50 can be expanded into a dual-antenna structure of a co-radiator through the excitation of the transverse and longitudinal modes and operate in two resonant frequency bands. The isolation degree between the two antennas of the co-radiator is relatively high (for example, the isolation degree is below 15). In one implementation manner, one of the resonant frequency bands can cover the N77 frequency band (3.3 GHz - 4.2 GHz). The other resonant frequency band can cover the WI FI 5G frequency band (5.15 GHz - 5.875 GHz).

[0191] It can be understood that the third radiator 50 in this implementation manner includes a third feeding point 54 and a fourth feeding point 55. Both the third feeding point 54 and the fourth feeding point 55 can be located at the first end 51 of the third radiator 50. Among them, the third feeding point 54 can be arranged close to the third end 56. The fourth feeding point 55 can be located between the third end 56 and the fourth end 57. In this way, the third feeding point 54 and the fourth feeding point 55 can respectively excite a first current in the first direction and a second current in the second direction on the third radiator 50. The first current is orthogonal to the second current. That is to say, the third feeding point 54 and the fourth feeding point 55 can respectively excite a transverse mode and a longitudinal mode on the third radiator 50. The third radiator 50 can be expanded into a dual-antenna structure of a co-radiator through the excitation of the transverse and longitudinal modes to improve the antenna performance of the electronic device 1000.

[0192] In some embodiments, at least one notch 58 may also be provided at the second end portion 52 of the third radiator 50. The shape of the notch 58 may be generally elongated. In this way, by providing the notch 58 at the second end portion 52, the electrical length of the third radiator 50 in the first direction can be increased, so that the third radiator 50 can support resonance at a lower frequency band, which is beneficial to improving the antenna performance.

[0193] In other embodiments, the camera decoration assembly 100 may also only include the first radiator 30 and the second radiator 40, or the camera decoration assembly 100 may also only include the first radiator 30 and the third radiator 50.

[0194] It should be noted that, without conflict, the features in the embodiments of the present application can be combined with each other, and any arbitrary combination of features in different embodiments is also within the protection scope of the present application. That is to say, the above-described multiple embodiments can also be arbitrarily combined according to actual needs.

[0195] It should be noted that all the above drawings are exemplary illustrations of the present application and do not represent the actual size of the product. Also, the dimensional ratio relationship between the components in the drawings does not serve as a limitation on the actual product of the present application.

[0196] The above are only some embodiments of the present application. The protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed in the present application, and all should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
