Technical Field

[0002] The present application relates to the field of wireless communications, and in particular to a camera decoration component and an electronic device. Background Art

[0003] Current terminal electronic devices primarily utilize the frame as the antenna radiator. As electronic devices become increasingly compact and lightweight, the challenges to antenna performance are increasing. The increasing number of functions required of electronic devices places greater demands on antenna bandwidth, efficiency, and radiation patterns. The limited design space for antennas in electronic devices restricts their performance. Summary of the Invention

[0004] The embodiments of the present application provide a camera decoration assembly and an electronic device, which are intended to utilize the internal space of the camera decoration assembly to set an antenna radiator to relieve the antenna layout pressure on the frame of the electronic device and improve the antenna performance of the electronic device.

[0005] In a first aspect, a camera decorative assembly is provided. The camera decorative assembly includes a decorative body, the decorative body including a metal portion, at least a portion of which forms a first radiator. The camera decorative assembly is configured to be mounted on a housing of an electronic device. The first radiator includes a first feed point and at least one first ground point spaced apart. The first feed point is configured to electrically connect to a first feed terminal of the electronic device, and the first ground point is configured to electrically connect to a floor of the electronic device. The antenna device of the electronic device is configured to communicate in a first frequency band. The first radiator is configured to support communication in the first frequency band. The antenna device and the first radiator are electrically connected to the same radio frequency chip.

[0006] It is understandable that the camera decoration assembly 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 can 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 can be used to support communication in the first frequency band, that is, the first radiator can be at the same frequency as the antenna device. The first radiator and the antenna device are electrically connected to the same RF chip, so that the first radiator and the antenna device can serve as receiving antennas with the same function, and perform diversity synthesis through the same RF chip to achieve improved antenna performance. At the same time, the first radiator is formed by the metal part of at least part of the decoration body, and the metal part of the decoration body can achieve "one thing for multiple uses", so that the first radiator can improve the antenna performance without occupying the limited antenna layout space on the side of the electronic device, which is conducive to releasing the antenna layout pressure of the frame of the electronic device.

[0007] In one possible implementation, the first frequency band corresponds to a satellite communication frequency band, used to support satellite messaging, satellite telephony, and / or satellite internet access. Thus, by electrically connecting the first radiator and the antenna assembly to the same satellite communication chip / RF chip, the satellite communication performance of the electronic device is improved, thereby effectively enhancing the user experience when using the electronic device for satellite communication.

[0008] In one possible implementation, a first frame radiator is provided on the frame of the electronic device, and the antenna device includes the first frame radiator. The first frame radiator is spaced apart from the first frame radiator, and the first frame radiator and the first radiator are electrically connected to the same RF chip. In this way, the first frame radiator and the first radiator are electrically connected to the same RF chip, and diversity synthesis is performed using the same RF chip to improve antenna performance.

[0009] In one possible implementation, the first frame radiator is located on the top edge of the electronic device. This facilitates antenna alignment when used as a satellite antenna radiator, improving signal reception sensitivity and enhancing the user experience.

[0010] 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 being fixed to opposite sides of the top edge, the distance between the decorative element body and the first side edge being a first distance, the distance between the decorative element body and the second side edge being a second distance, and the ratio of the first distance to the second distance being in a range of 0.8 to 1.2. In this manner, the decorative element body can be centered relative to the first side edge and the second side edge. When the first frame radiator is positioned at the top edge, the radiation pattern of the first radiator can complement that of the first frame radiator, and the first radiator and the first frame radiator can combine to form a wide beam, so that the radiation generated by the first radiator and the first frame radiator can have good transmission and reception capabilities in a wide range of directions.

[0011] In one possible implementation, the first frame radiator has a first open end, a second open end, and a conductive portion extending between the first and second open ends along the length of the top edge. The distance from the center of the top edge to the first open end is a first spacing, the distance from the center of the top edge to the second open end is a second spacing, and the ratio of the first spacing to the second spacing is within a range of 0.8 to 1.2. In this way, the first frame radiator can be located at the top edge, centered on the top edge. When the first frame radiator is a satellite antenna radiator, this facilitates antenna alignment, improves signal reception sensitivity, and enhances the user experience.

[0012] In a possible implementation, the antenna device and the first radiator are both used to receive signals in the first frequency band.

[0013] It is understandable that the first radiator and the antenna device can serve as receiving antennas with the same function and perform diversity synthesis through the same RF chip, thereby achieving an expanded directional pattern, or an expanded beam, or an expanded bandwidth, which is beneficial to enhancing the electronic device's ability to receive signals in the first frequency band to achieve improved antenna performance. For example, when a user performs satellite communication, it is necessary to point the antenna's maximum radiation direction toward the satellite to achieve satellite alignment (i.e., establish a communication connection with the satellite). When the antenna beam is narrow (e.g., less than ±10°), the antenna's alignment requirements are high, and changes in the electronic device's attitude have a greater impact on the quality of satellite communication. When the antenna beam is wide (e.g., more than ±30°), the alignment requirements are low, and changes in the electronic device's attitude have a smaller impact on the quality of satellite communication. In this embodiment, the directional pattern generated by the first radiator can complement the directional pattern generated by the antenna device, and a wide beam can be synthesized, thereby expanding the directional pattern and beam, which is beneficial to reducing the satellite alignment requirements of the electronic device during satellite communication, thereby effectively reducing the impact of changes in the electronic device's attitude on the quality of satellite communication, and is beneficial to improving the satellite communication performance of the electronic device. Among them, the antenna device and the first radiator are both used to receive signals in the satellite communication frequency band. In this way, the directional pattern generated by the first radiator can complement the directional 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 higher, which is conducive to enhancing the ability of the electronic device to receive signals and improving the user experience.

[0014] In one possible implementation, the camera decoration assembly further includes a second radiator, the second radiator is fixed to the first radiator, the second radiator includes a second feeding point, and the second feeding point is used to electrically connect to the second feeding end of the electronic device.

[0015] It is understandable that the camera decorative assembly in this embodiment may include a first radiator and a second radiator. The first radiator may be formed from at least a portion of the metal portion of the decorative component body. The first radiator and the second radiator may serve as radiators for two different antennas. The second radiator may be fixedly connected to the surface of the first radiator. In this way, the second radiator may be arranged in close proximity to the first radiator, and the two may reuse the space of the camera decorative assembly, thereby improving antenna performance without occupying the limited antenna layout space in the frame of the electronic device, which helps to relieve the antenna layout pressure on the frame of the electronic device.

[0016] In one possible implementation, the second radiator is an NFC coil or a wireless charging coil. This allows the first and second radiators to reuse the space of the camera decorative assembly, thereby improving antenna performance without occupying the limited antenna layout space in the electronic device's frame, thereby alleviating antenna layout pressure on the electronic device's frame.

[0017] In a second aspect, a camera decorative assembly is provided. The camera decorative assembly includes a decorative body, the decorative body including a metal portion, at least part of which forms a first radiator. The camera decorative assembly also includes a second radiator, which is fixed to the first radiator. The camera decorative assembly is configured to be mounted on a housing of an electronic device. The first radiator includes a first feed point and at least one first ground point, spaced apart from each other. The first feed point is configured to electrically connect to a first feed terminal of the electronic device, and the first ground point is configured to electrically connect to a floor of the electronic device. The second radiator includes a second feed point, which is configured to electrically connect to a second feed terminal of the electronic device.

[0018] It is understandable that the camera decorative assembly in this embodiment may include a first radiator and a second radiator. The first radiator may be formed from at least a portion of the metal portion of the decorative component body. The first radiator and the second radiator may serve as radiators for two different antennas. The second radiator may be fixedly connected to the surface of the first radiator. In this way, the second radiator may be arranged in close proximity to the first radiator, and the two may reuse the space of the camera decorative assembly, thereby improving antenna performance without occupying the limited antenna layout space in the frame of the electronic device, which helps to relieve the antenna layout pressure on the frame of the electronic device.

[0019] In one possible implementation, the second radiator is an NFC coil or a wireless charging coil. This allows the first and second radiators to reuse the space of the camera decorative assembly, thereby improving antenna performance without occupying the limited antenna layout space in the electronic device's frame, thereby alleviating antenna layout pressure on the electronic device's frame.

[0020] In one possible implementation, the camera decorative assembly further includes an isolation layer secured between the first and second radiators, the isolation layer being made of ferrite or nanocrystals. This allows the isolation layer to exhibit magnetic conductor properties at low frequencies and electrical conductor properties with low conductivity at high frequencies, thereby preventing resonance between the second radiator and the first radiator and providing improved isolation between the second and first radiators.

[0021] In one possible implementation, the camera decorative assembly further includes an inductor structure connected in series between the second feed point and the feed end of the electronic device. Thus, by connecting the inductor structure in series with the second feed point, the inductor structure can act as a low-pass filter to cut off high-frequency signals input to the second radiator, thereby preventing the influence of clutter.

[0022] In one possible implementation, the camera decoration assembly also includes a third radiator, the first radiator is provided with a groove, the third radiator is at least partially accommodated in the groove, the third radiator includes a third feeding point, and the third feeding point is used to electrically connect to the third feeding end of the electronic device.

[0023] It is understood that the camera decorative assembly in this embodiment may further include a third radiator, which may be at least partially disposed within the groove of the first radiator. In this way, the first and third radiators can reuse the space of the camera decorative assembly, thereby improving antenna performance without occupying the limited antenna layout space in the electronic device's frame, thereby relieving the antenna layout pressure in the electronic device's frame.

[0024] In one possible implementation, the first radiator is configured to support communications in a first frequency band, and / or the third radiator is configured to support communications in a second frequency band. In this way, the first and third radiators can operate in different frequency bands, thereby improving antenna performance without occupying the limited antenna layout space within the electronic device's frame, thereby alleviating antenna layout pressure within the electronic device's frame.

[0025] In a third aspect, a camera decorative assembly is provided. The camera decorative assembly includes a decorative body, the decorative body includes a metal portion, at least part of the metal portion forms a first radiator, the first radiator is provided with a groove, the camera decorative assembly also includes a third radiator, the third radiator is at least partially accommodated in the groove, the first radiator is used for communication in a first frequency band, the third radiator is used for communication in a second frequency band, and the camera decorative assembly is used to be installed in the 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 to electrically connect to the first feeding end of the electronic device, and the first grounding point is used to electrically connect to the floor of the electronic device.

[0026] It is understood that the camera decorative assembly in this embodiment may further include a third radiator, which may be at least partially disposed within the groove of the first radiator. In this way, the first and third radiators can reuse the space of the camera decorative assembly, thereby improving antenna performance without occupying the limited antenna layout space in the electronic device's frame, thereby relieving the antenna layout pressure in the electronic device's frame.

[0027] In one possible implementation, the third radiator includes a third grounding point and a third feeding point spaced apart from each other, the third grounding point being electrically connected to the first radiator, and the third feeding point being electrically connected to a third feeding terminal of the electronic device. In this way, the first radiator can also serve as a reference ground for the third radiator.

[0028] In one possible implementation, the camera decorative assembly further includes a feed line and at least one feed line grounding member. A through-hole is provided at the bottom of the groove. One end of the feed line is electrically connected to the third feed point, and the other end of the feed line passes through the through-hole and is electrically connected to the third feed end of the electronic device. One end of the feed line grounding member is connected to the bottom wall of the groove, and the other end of the feed line grounding member is electrically connected to the floor of the electronic device. The feed line grounding member is located between the feed line and the inner wall of the through-hole. In this way, the impedance of the third feed point of the third radiator can be adjusted by providing the feed line grounding member, thereby improving antenna performance.

[0029] In one possible implementation, the camera decoration assembly also includes a fourth radiator, which is at least partially accommodated in the groove and is spaced apart from the third radiator. The fourth radiator includes a fourth grounding point, the fourth grounding point is electrically connected to the floor of the electronic device, and the fourth radiator is coupled to the third radiator.

[0030] It can be understood that in this embodiment, a composite antenna is formed by arranging a fourth radiator and a third radiator in the groove. Among them, the third radiator can serve as a main radiator, and the fourth radiator can serve as a 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 conducive to broadening the bandwidth of the composite antenna and improving antenna performance. At the same time, the fourth radiator can reuse the space of the camera decorative component, thereby improving the antenna performance without occupying the limited antenna layout space in the frame of the electronic device, which is conducive to relieving the antenna layout pressure of the frame of the electronic device.

[0031] In one possible implementation, the third radiator also includes a fourth feeding point, which is electrically connected to a fourth feeding terminal 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.

[0032] It will be understood that the third radiator in this embodiment includes a third feed point and a fourth feed point. The third feed point and the fourth feed point can respectively excite a first current along a first direction and a second current along a second direction on the third radiator. The first current is orthogonal to the second current. That is, the third feed point and the fourth feed point can respectively excite a transverse mode and a longitudinal mode on the third radiator. By exciting the transverse and longitudinal modes, the third radiator can be expanded into a dual-antenna structure with a common radiator, thereby improving the antenna performance of the electronic device.

[0033] In a fourth aspect, an electronic device is provided. The electronic device includes a housing, a camera module, and the aforementioned camera decorative assembly. The housing includes a middle frame and a back cover. The camera module is fixed to the middle frame. The back cover is provided with a light-transmitting hole, and the light inlet of the camera module is exposed relative to the light-transmitting hole. The camera decorative assembly is fixed to the back cover and covers the light-transmitting hole. The decorative part body of the camera decorative assembly is provided with an avoidance hole, which is arranged opposite to the light inlet of the camera module.

[0034] It is understandable that the camera decoration assembly 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 can 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 can be used to support communication in the first frequency band, that is, the first radiator can be at the same frequency as the antenna device. The first radiator and the antenna device are electrically connected to the same RF chip, so that the first radiator and the antenna device can serve as receiving antennas with the same function, and perform diversity synthesis through the same RF chip to achieve improved antenna performance. At the same time, the first radiator is formed by the metal part of at least part of the decoration body, and the metal part of the decoration body can achieve "one thing for multiple uses", so that the first radiator can improve the antenna performance without occupying the limited antenna layout space on the side of the electronic device, which is conducive to releasing the antenna layout pressure of the frame of the electronic device.

[0035] In one possible implementation, the first radiator includes a first region and a second region. The projection of the first region along the thickness of the electronic device does not cover the camera module, while the projection of the second region along the thickness of the electronic device covers the camera module. The first radiator includes a first feed point and at least one first ground point, and the first feed point and the multiple first ground points are all located in the first region. In this way, the first feed point and the first ground point can be positioned away from the camera module to avoid affecting the performance of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] The following explains the terms that may appear in the embodiments of the present application.

[0060] It should be understood that the term "and / or" as used herein is simply a term used to describe the existence of three possible relationships between related objects. For example, "A and / or B" can represent the existence of A alone, the existence of both A and B, and the existence of B alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0061] When used in this application, "within the range of...", unless it is specifically stated that the end value is not included, it is assumed that both end values ​​of the range are included. For example, in the range of 1 to 5, the two values ​​1 and 5 are included.

[0062] Coupling: can be understood as direct coupling and / or indirect coupling, and "coupling connection" can be understood as direct coupling connection and / or indirect coupling connection. Direct coupling can also be referred to as "electrical connection", which is understood as the physical contact and electrical conduction between components; it can also be understood as the form in which different components in the circuit structure are connected through physical lines such as printed circuit board (PCB) copper foil or wires that can transmit electrical signals; "indirect coupling" can be understood as two conductors being electrically conductive in an airless / non-contact manner. In one embodiment, indirect coupling can also be referred to as capacitive coupling, for example, signal transmission is achieved by forming an equivalent capacitance through coupling between the gap between two conductive parts.

[0063] Component / device: includes at least one of lumped component / device and distributed component / device.

[0064] Lumped component / device: This refers to all components whose size is much smaller than the wavelength relative to the circuit's operating frequency. For a signal, the component's characteristics remain constant at all times, regardless of frequency.

[0065] Distributed components / devices: Unlike lumped components, if the size of the component is similar to or larger than the wavelength relative to the circuit operating frequency, then when the signal passes through the component, the characteristics of each point of the component itself will vary due to changes in the signal. At this time, the component as a whole cannot be regarded as a single entity with fixed characteristics, but should be called a distributed component.

[0066] Capacitance: This can be understood as lumped capacitance and / or distributed capacitance. Lumped capacitance refers to capacitive components, such as capacitors; distributed capacitance (or distributed capacitance) refers to the equivalent capacitance formed by two conductive parts separated by a certain gap.

[0067] Inductance: This can be understood as lumped inductance and / or distributed inductance. Lumped inductance refers to inductive components, such as inductors; distributed inductance (or distributed inductance) refers to the equivalent inductance formed by a certain length of conductive material.

[0068] Radiator: A device in an antenna used to receive / send electromagnetic wave radiation. In some cases, the narrow meaning of "antenna" is the radiator, which converts the guided wave energy from the transmitter into radio waves, or converts radio waves into guided wave energy, used to radiate and receive radio waves. The modulated high-frequency current energy (or guided wave energy) generated by the transmitter is transmitted to the transmitting radiator via the feeder line, where it is converted into a certain polarized electromagnetic wave energy and radiated in the desired direction. The receiving radiator converts the electromagnetic wave energy of a certain polarization from a specific direction in space into modulated high-frequency current energy and transmits it to the receiver input via the feeder line.

[0069] The radiator may include a conductor with a specific shape and size, such as a linear or sheet shape, etc., and the present application does not limit the specific shape. In one embodiment, the linear radiator can be simply referred to as a linear antenna. In one embodiment, the linear radiator can be implemented by a conductive frame, and can also be called a frame antenna. In one embodiment, the linear radiator can be implemented by a bracket conductor, and can also be called a bracket antenna. In one embodiment, the wire diameter (for example, including thickness and width) of the linear radiator, or the radiator of the linear antenna is much smaller than the wavelength (for example, the wavelength of the medium) (for example, less than 1 / 16 of the wavelength), and the length can be comparable to the wavelength (for example, the wavelength of the medium) (for example, the length is about 1 / 8 of the wavelength, or 1 / 8 to 1 / 4, or 1 / 4 to 1 / 2, or longer). The main forms of linear antennas include dipole antennas, half-wave oscillator antennas, monopole antennas, loop antennas, and inverted F antennas (also known as IFA, Inverted F Antenna). For example, for a dipole antenna, each dipole antenna typically includes two radiating branches, and each branch is fed by a feeding portion from the feeding end of the radiating branch. For example, an inverted-F antenna (IFA) can be regarded as a monopole antenna with a ground path added. The IFA antenna has a feeding point and a grounding point, and is called an inverted-F antenna because its side view is an inverted-F shape. 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 a 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 a silver paste, etc. The shape of the sheet radiator includes circular, rectangular, annular, etc., and 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 floor, wherein the dielectric substrate is arranged between the radiator and the floor.

[0070] The radiator may also include a slot or slot formed in a conductor, for example, a closed or semi-closed slot or slot formed in a grounded conductor surface. In one embodiment, a slotted or slotted radiator may be referred to as a slot antenna or slot antenna. In one embodiment, the radial dimension (e.g., including the width) of the slot or slot of the slot antenna / slot 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., the length is approximately 1 / 8 of the wavelength, or 1 / 8 to 1 / 4, or 1 / 4 to 1 / 2, or longer). In one embodiment, a radiator with a closed slot or slot may be referred to as a closed slot antenna. In one embodiment, a radiator with a semi-closed slot or slot (e.g., a closed slot or slot with an additional opening) may be referred to as an open slot antenna. In some embodiments, the slot is elongated. In some embodiments, the slot is approximately half a wavelength (e.g., the dielectric wavelength). In some embodiments, the slot is approximately an integer multiple of the wavelength (e.g., one wavelength). In some embodiments, the slot can be fed with a transmission line spanning one or both sides, thereby exciting a radio frequency electromagnetic field in the slot and radiating electromagnetic waves into space. In one embodiment, the radiator of a slot antenna or slot antenna can be implemented as a conductive frame with both ends grounded, also known as a frame antenna. In this embodiment, the slot antenna or slot antenna can be considered to include a linear radiator spaced from the floor and grounded at both ends, thereby forming a closed or semi-enclosed slot or slot. In one embodiment, the radiator of a slot antenna or slot antenna can be implemented as a bracket conductor with both ends grounded, also known as a bracket antenna.

[0071] The feed circuit is a combination of all circuits used for receiving and transmitting radio frequency signals. The feed circuit may include a transceiver and an RF front end circuit. In some cases, the "feed circuit" is understood in a narrow sense as a radio frequency chip (RFIC, Radio Frequency Integrated Circuit), and the RFIC can be considered to include an RF front end chip and a transceiver. The feed 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.

[0072] In some embodiments, the electronic device may also include a test socket (or RF socket or RF test socket). This test socket can be used to insert a coaxial cable and test the characteristics of the RF front-end circuit or antenna radiator through the cable. The RF front-end circuit can be considered as the circuit portion coupled between the test socket and the transceiver.

[0073] In some embodiments, the RF front-end circuit may be integrated into a RF front-end chip in the electronic device, or the RF front-end circuit and the transceiver may be integrated into a RF chip in the electronic device.

[0074] 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, transmitting signals through a radio frequency channel in a transceiver (for example, a port (pin) of a radio frequency chip); they can also share a radio frequency front-end circuit, for example, processing signals through a tuning circuit or amplifier in a radio frequency front-end.

[0075] It should also be understood that two feeding circuits in the first / second / ...Nth feeding circuit in the present application usually correspond to two radio frequency test sockets in the electronic device.

[0076] 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 feed circuit and the corresponding radiator. In another embodiment, the matching circuit is coupled between the test socket and the radiator. Typically, the matching circuit is a combination of circuits coupled between the radiator and the ground plane. In one embodiment, the matching circuit may include a tuning circuit and / or electronic components, and the tuning circuit may be an electronic component used to switch the coupling connection of the radiator. The matching circuit performs impedance matching and / or frequency tuning functions. Generally, it is considered to be part of the antenna.

[0077] The grounding structure / feeding structure may include a connector, such as a metal spring, through which the radiator is coupled to the floor / feeding structure is coupled to the feeding circuit. In some embodiments, the feeding structure may include a transmission line / feeding line, and the grounding structure may include a grounding wire.

[0078] End / Point: The "end / point" in the terms "first end / second end / feeding end / grounding end / feeding point / grounding point / connection point" of an antenna radiator should not be narrowly understood as an endpoint or end physically disconnected from other radiators. It can also be considered as a point or segment on a continuous radiator. In one embodiment, an "end / point" may include a connection / coupling area on an antenna radiator that couples to other conductive structures. For example, a feeding end / feeding point may be a coupling area on an antenna radiator that couples to a feeding structure or feeding circuit (e.g., an area facing a portion of the feeding circuit). In another example, a grounding end / grounding point may be a connection / coupling area on an antenna radiator that couples to a grounding structure or grounding circuit. Open End, Closed End: In some embodiments, open end and closed end refer to, for example, whether or not the antenna is grounded. A closed end is grounded, while an open end is not. In some embodiments, open end and closed end refer to, for example, other conductive bodies. A closed end is electrically connected to other conductive bodies, while an open end is not electrically connected to other conductive bodies. In one embodiment, an open end may 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 may also be referred to as a ground end or a short-circuit end. It should be understood that in some embodiments, other conductors may be coupled to each other through the open end to transfer coupling energy (which may be understood as transferring current).

[0079] In some embodiments, the "closed end" can also be understood from the perspective of current distribution. The closed end or the grounded end can be understood as a point with larger current on the radiator, or as a point with smaller electric field on the radiator. In one embodiment, the current distribution characteristics of larger current / smaller electric field can be maintained by coupling electronic devices (for example, capacitors, inductors, etc.) through the closed end. In one embodiment, the current distribution characteristics of larger current / smaller electric field can be maintained by opening a gap at or near the closed end (for example, a gap filled with insulating material).

[0080] In some embodiments, the understanding of "open end" can also be viewed from the perspective of current distribution. The open end or floating end can be understood as a point with low current on the radiator, or as a point with high electric field on the radiator. In one embodiment, coupling electronic devices (for example, capacitors, inductors, etc.) through the open end can maintain the current distribution characteristics of the low current point / high electric field point.

[0081] It should be understood that coupling the radiator end at a gap (from the perspective of the radiator structure, it is similar to the radiator at the opening of the open end or the suspended end) with electronic devices (for example, capacitors, inductors, etc.) can make the radiator end a point with larger current / smaller electric field. In this case, it should be understood that the radiator end at the gap is actually a closed end or a grounded end, etc.

[0082] The “suspended radiator” mentioned in the embodiments of the present application means that the radiator is not directly connected to the feed line / feed branch and / or the ground line / ground branch, but is fed and / or grounded through indirect coupling.

[0083] It should be understood that the "suspended" in "suspended end" and "suspended radiator" does not mean that there is no structure around the radiator to support it. In one embodiment, the suspended radiator can be, for example, a radiator disposed on the inner surface of the insulating back cover.

[0084] The current same direction / reverse direction mentioned in the embodiments of the present application should be understood as the direction of the main current on the conductor on the same side is the same direction / reverse direction. For example, when stimulating a unidirectional distributed current on a conductor that is bent or ring-shaped (for example, the current path is also bent or ring-shaped), it should be understood that, for example, the main currents stimulated on the conductors on both sides of the ring conductor (for example, a conductor surrounding a gap, on the conductors on both sides of the gap) are opposite in direction, which still falls within the definition of the unidirectional distributed current in the embodiments of the present application. In one embodiment, the current same direction on a conductor can refer to the current on the conductor having no reversal point. In one embodiment, the current reverse on a conductor can refer to the current on the conductor having at least one reversal point. In one embodiment, the current same direction on two conductors can refer to the current on both conductors having no reversal point and flowing in the same direction. In one embodiment, the current reverse on two conductors can refer to the current on both conductors having no reversal point and flowing in opposite directions. The current same direction / reversal on multiple conductors can be understood accordingly.

[0085] Resonance / resonance frequency: The resonant frequency is also called the resonance frequency. The resonant frequency can have a frequency range, that is, the frequency range in which resonance occurs. The frequency corresponding to the strongest resonance point is the center frequency point frequency. The return loss characteristic of the center frequency can be less than -20dB. It should be understood that, unless otherwise specified, the antenna / radiator mentioned in this application produces a "first / second... resonance", where the first resonance should be the fundamental mode resonance generated by the antenna / radiator, or in other words, the lowest frequency resonance 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 generate a corresponding fundamental mode resonance.

[0086] Resonant frequency band: The range of the resonant frequency is the resonant frequency band. The return loss characteristic of any frequency point in the resonant frequency band can be less than -6dB or -5dB.

[0087] Communication frequency band / operating frequency band: Regardless of the type of antenna, it always operates within a certain frequency range (bandwidth). For example, an antenna that supports the B40 frequency band operates between 2300MHz and 2400MHz, or in other words, the antenna's operating frequency band includes the B40 frequency band. The frequency range that meets the required specifications can be considered the antenna's operating frequency band.

[0088] The resonant frequency band and the operating frequency band may be the same, or may partially overlap. In one embodiment, one or more resonant frequency bands of the antenna may overlap one or more operating frequency bands of the antenna.

[0089] Electrical length: It can refer to the ratio of 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:

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

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

[0092] It should be understood that the wavelength of the radiation signal in air can be calculated as follows: (wavelength in air, or wavelength in vacuum) = speed of light / frequency, where frequency is the frequency of the radiation signal (MHz) and the speed of light can be taken as 3×108 m / s. The wavelength of the radiation signal in the medium can be calculated as follows: Wherein, ε is the relative dielectric constant of the medium. The wavelength in the embodiments of the present application generally refers to the dielectric wavelength, which can be the dielectric wavelength corresponding to the center frequency of the resonant frequency, or the dielectric wavelength corresponding to the center frequency of the working frequency band supported by the antenna. For example, assuming that the center frequency of the B1 uplink frequency band (resonant frequency is 1920MHz to 1980MHz) is 1955MHz, the wavelength can be the dielectric wavelength calculated using the frequency of 1955MHz. Not limited to the center frequency, "dielectric wavelength" can also refer to the dielectric wavelength corresponding to the non-center frequency of the resonant frequency or the working frequency band. For ease of understanding, the dielectric wavelength mentioned in the embodiments of the present application can be simply calculated by the relative dielectric constant of the medium filled on one or more sides of the radiator.

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

[0094] Antenna radiation efficiency refers to the ratio of the power radiated by an antenna into space (i.e., the power effectively converted into electromagnetic waves) to the active power input to the antenna. Active power input to the antenna = antenna input power minus power loss; power loss primarily includes return loss and metal ohmic loss and / or dielectric loss. Radiation efficiency measures the antenna's radiation capability, and both metal loss and dielectric loss contribute to it.

[0095] Those skilled in the art will understand that efficiency is generally expressed as a percentage, which has a corresponding conversion relationship with dB. The closer the efficiency is to 0 dB, the better the efficiency of the antenna.

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

[0097] Antenna return loss can be expressed using the S11 parameter, a type of S parameter. S11 represents the reflection coefficient and characterizes the antenna's transmission efficiency. The S11 parameter is typically negative. A smaller S11 parameter indicates lower antenna return loss and less energy reflected back from the antenna itself, meaning more energy actually enters the antenna and higher system efficiency. A larger S11 parameter indicates greater antenna return loss and lower system efficiency.

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

[0099] Antenna pattern: Also known as radiation pattern. It is a graph showing how the relative field strength (normalized modulus) of the antenna's radiation field changes with direction at a certain distance from the antenna (far field). It is usually represented by two mutually perpendicular plane patterns passing through the antenna's direction of maximum radiation.

[0100] Antenna patterns typically have multiple radiation beams. The beam with the strongest radiation intensity is called the main lobe, while the remaining beams are called side lobes. Among the side lobes, those in the opposite direction of the main lobe are also called back lobes.

[0101] Directivity: Also known as the directivity of an antenna, it refers to the ratio of the maximum power density to the average power density in the antenna pattern at a certain distance from the antenna (far field). It is a dimensionless ratio greater than or equal to 1. It can be used to indicate the energy radiation characteristics of an antenna. A larger directivity indicates that the antenna radiates more energy in a certain direction and the energy radiation is more concentrated.

[0102] Antenna Gain: This is used to measure how well an antenna radiates input power. Generally, the narrower the main lobe of an antenna pattern and the smaller the side lobes, the higher the antenna gain.

[0103] Antenna polarization direction: At a given point in space, the electric field strength E (vector) is a function of time t. As time passes, the endpoints of the vector periodically trace a trajectory in space. If this trajectory is straight and perpendicular to the ground, it is called vertical polarization. If it is horizontal to the ground, it is called horizontal polarization. If this trajectory is elliptical or circular and rotates clockwise or to the right as viewed along the propagation direction, it is called right-hand circular polarization (RHCP). If it rotates counterclockwise or to the left as viewed along the propagation direction, it is called left-hand circular polarization (LHCP).

[0104] Ground (GND): can generally refer to at least a part of any grounding layer, grounding plate, or grounding metal layer in an electronic device (such as a mobile phone), or at least a part of any combination of any of the above grounding layers, grounding plates, or grounding components, etc. "Ground" can be used for grounding components in an electronic device. In one embodiment, "ground" can be the grounding layer of a circuit board of an electronic device, or it can be the grounding plate formed by the middle frame of the electronic device, or the grounding 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 to 14-layer board having 8, 10, 12, 13, or 14 layers of conductive material, or an element separated and electrically insulated by a dielectric layer or insulating layer such as fiberglass, polymer, etc. In one embodiment, the circuit board includes a dielectric substrate, a grounding layer, and a routing layer, and the routing layer and the grounding layer are electrically connected through vias. In one embodiment, components such as a display, touch screen, input buttons, transmitter, processor, memory, battery, charging circuit, and system-on-chip (SoC) structures can be mounted on or connected to a circuit board, or electrically connected to a trace layer and / or ground layer in the circuit board. For example, a radio frequency source can be located on a trace layer.

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

[0106] Grounding refers to coupling to the ground / floor in any manner. In one embodiment, grounding can be achieved through physical grounding, such as physical grounding at a specific location on the frame using a portion of the midframe's structural components (or referred to as a physical ground). In one embodiment, grounding can be achieved through device grounding, such as through a series or parallel connection of a capacitor, inductor, or resistor (or referred to as a device ground).

[0107] In the embodiments of the present application, reference to / between a certain numerical range includes the endpoint values ​​of the range unless otherwise specified. For example, a range of 2 to 10 includes the two endpoint values ​​of 2 and 10.

[0108] The following will introduce the two antenna modes involved in this application in conjunction with Figures 1a to 1d. Among them, Figure 1a is the structure of the common mode mode of an antenna 91 provided in this application. Figure 1b is a schematic diagram of the distribution of current and electric field corresponding to the common mode mode of the antenna 91 shown in Figure 1a. Figure 1c is the structure of the differential mode mode of another antenna 92 ​​provided in this application. Figure 1d is a schematic diagram of the distribution of current and electric field corresponding to the differential mode mode of the antenna 92 ​​shown in Figure 1c. The antenna radiator in Figures 1a to 1d is open at both ends, and its common mode mode and differential mode can be called line common mode mode and line differential mode mode, respectively.

[0109] It should be understood that the “common-differential mode” or “CM-DM mode” in this application refers to a line common mode mode and a line differential mode mode generated on the same radiator.

[0110] 1. Wire common mode (CM) mode

[0111] Figure 1a shows that the radiator of antenna 91 is open at both ends and is connected to a feeding circuit (not shown) 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 a feeding line 912. It should be understood that symmetrical feeding can be understood as one end of the feeding circuit being connected to the radiator and the other end being coupled to the floor to achieve grounding, wherein the connection point between the feeding circuit and the radiator (feeding point) is located at the center of the radiator. The center of the radiator can, for example, be the midpoint of the geometric structure, or the midpoint of the electrical length (or an area within a certain range near the above midpoint).

[0112] The middle position 911 of the antenna 91 may be, for example, the geometric center of the antenna, or the midpoint of the electrical length of the radiator. For example, the connection between the feed line 912 and the antenna 91 covers the middle position 911 .

[0113] Figure 1b shows the current and electric field distribution of antenna 91. As shown in Figure 1b, the current is distributed in opposite directions on both sides of the middle position 911, for example, symmetrically; the electric field is distributed in the same direction on both sides of the middle position 911. As shown in Figure 1b, the current at the feed line 912 is distributed in the same direction. Based on the same direction distribution of the current at the feed line 912, the feeding shown in Figure 1a can be called line CM feeding. Based on the opposite distribution of the current on both sides of the connection between the radiator and the feed line 912, the antenna mode shown in Figure 1b can be called a line CM mode (it can also be simply called a CM mode. For example, for a wire antenna, the CM mode refers to the line CM mode). The current and electric field shown in Figure 1b can be respectively called the current and electric field of the line CM mode.

[0114] The current is stronger at center 911 of antenna 91 (the highest current point is near center 911 of antenna 91) and weaker at both ends of antenna 91, as shown in FIG1b. The electric field is weaker at center 911 of antenna 91 and stronger at both ends of antenna 91.

[0115] 2. Line differential mode (DM) mode

[0116] As shown in Figure 1c, the left and right ends of the two radiators of antenna 92 ​​are open, and a feed circuit is connected at a center position 921. In one embodiment, antenna 92 ​​uses an anti-symmetrical feed. One end of the feed circuit is connected to one of the radiators via a feed line 922, and the other end of the feed circuit is connected to the other radiator via a feed line 922. Center position 921 can be the geometric center of antenna 92 ​​or the gap formed between the radiators.

[0117] It should be understood that the "center-antisymmetric feeding" mentioned in this application can be understood as the positive and negative poles of the feed unit being connected to two connection points near the aforementioned midpoint of the radiator. In one embodiment, the signals output by the positive and negative poles of the feed unit have the same amplitude but opposite phases, for example, a phase difference of 180°±10°.

[0118] Figure 1d shows the current and electric field distribution of antenna 92. As shown in Figure 1d, the current is distributed in the same direction on both sides of the center position 921 of antenna 92, for example, in an antisymmetric distribution; the electric field is distributed in opposite directions on both sides of the center position 921. As shown in Figure 1d, the current at feed line 922 is distributed in opposite directions. Based on the opposite current distribution at feed line 922, the feeding shown in Figure 1c can be referred to as linear DM feeding. Based on the current being distributed in the same direction on both sides of the connection between the radiator and feed line 922, the antenna pattern shown in Figure 1d can be referred to as a linear DM mode (or simply a DM mode, for example, for a linear antenna, a DM mode refers to a linear DM mode). The current and electric field shown in Figure 1d can be referred to as the current and electric field of the linear DM mode, respectively. It should be understood that based on the current being distributed in the same direction on both sides of the connection between the radiator and feed line 922, the antenna pattern shown in Figure 1d can also be referred to as a half-antenna mode, a half-wavelength mode, or simply a half-mode.

[0119] In one embodiment, in the line DM mode, or half mode, the current is stronger at the center 921 of antenna 92 ​​(the highest current point is near the center 921 of antenna 92) and weaker at the ends of antenna 92, as shown in FIG1d. The electric field is weaker at the center 921 of antenna 92 ​​and stronger at the ends of line antenna 92.

[0120] It should be understood that the antenna radiator can be understood as a metal structural member that generates radiation. The number of radiators can be one, as shown in Figures 1a and 1b, or two, as shown in Figures 1c and 1d, and can be adjusted according to actual design or production needs. For example, for the line CM mode, two radiators can be used as shown in Figures 1c and 1d, with the two ends of the two radiators arranged opposite each other and separated by a gap. A symmetrical feeding method is used at the two ends close to each other, for example, the same feed source signal is fed to the two ends of the two radiators close to each other, and an effect similar to the antenna structure shown in Figures 1a and 1b can also be achieved. Correspondingly, for the line DM mode, one radiator can be used as shown in Figures 1a and 1b, with two feeding points set in the middle of the radiator and an anti-symmetrical feeding method is used. For example, if the two symmetrical feeding points on the radiator are fed with signals with the same amplitude and opposite phase, an effect similar to the antenna structure shown in Figures 1c and 1d can also be achieved.

[0121] 3. Line CM-DM mode

[0122] 1a and 1b above respectively show that when both ends of the radiator are open, a line CM mode and a line DM mode are generated by adopting different feeding methods.

[0123] When the antenna uses asymmetric feeding (the feeding point is offset from the center of the radiator, including side or offset feeding), or the radiator's grounding point (where it couples with the floor) is asymmetric (the grounding point is offset from the center of the radiator), the antenna can simultaneously produce a first resonance and a second resonance, corresponding to the linear CM mode and the linear DM mode, respectively. For example, the first resonance corresponds to the linear CM mode, with the current and electric field distributions shown in Figure 1b. The second resonance corresponds to the linear DM mode, with the current and electric field distributions shown in Figure 1d.

[0124] It is understood that the specific embodiments described herein are intended only to explain the relevant inventions and are not intended to limit the inventions. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings. The technical solutions of the embodiments of this application will be described below in conjunction with the accompanying drawings.

[0125] Figure 2a is a schematic diagram of the structure of the electronic device 1000 provided in some embodiments of the present application. Figure 2b is a schematic diagram of the structure of the electronic device 1000 shown in Figure 2a from another perspective. Figure 2c is a schematic diagram of the partially exploded structure of the electronic device 1000 shown in Figure 2a in some embodiments.

[0126] As shown in Figures 2a to 2c, the electronic device 1000 can be an electronic device with a camera function, such as a mobile phone, a tablet computer, an e-reader, a laptop computer, a wearable device such as a watch. The electronic device 1000 of the embodiment shown in Figure 2a is described using 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 is understandable that the coordinate system of the electronic device 1000 can also be specifically set according to actual needs, and this application does not limit this.

[0127] Exemplarily, the electronic device 1000 may include a screen 200 and a housing 300. It will be understood that Figures 2a to 2c only schematically illustrate some components included in the electronic device 1000, and the actual shape, actual size, and actual structure of these components are not limited by Figures 2a to 2c. In other embodiments, when the electronic device 1000 is a device of other forms, the electronic device 1000 may also not include the screen 200. The screen 200 may be mounted on the housing 300. Figures 2a and 2b illustrate a structure in which the screen 200 and the housing 300 form a roughly rectangular parallelepiped. The screen 200 can be used to display images, text, etc. It should be understood that in the embodiments of the present application, it can be considered that when a user holds the electronic device 1000 (usually vertically and facing the screen 200), the orientation of the electronic device 1000 has a top, a bottom, a left side, and a right side. The top of the electronic device 1000 can face the sky. In this embodiment, the arrangement direction of the top and the bottom can be parallel to the Y-axis direction. The arrangement direction of the left portion and the right portion may be parallel to the X-axis direction.

[0128] For example, the housing 300 can be used to support the screen 200 and related components of the electronic device 1000. The housing 300 can include a middle frame 310 (housing) and a rear cover 320 (rear cover). The rear cover 320 and the screen 200 can be mounted on opposite sides of the middle frame 310. The arrangement of the rear cover 320 and the screen 200 can be parallel to the Z-axis. The rear cover 320 can be fixedly connected to the middle frame 310 by bonding, welding, or other methods. In this case, the screen 200, the middle frame 310, and the rear cover 320 can collectively enclose the interior space of the electronic device 1000. The interior space of the electronic device 1000 can be used to house internal components of the electronic device 1000, such as a battery, speaker, microphone, or earpiece. The rear cover 320 can be made of a metal material, a non-conductive material, such as a glass back cover, a plastic back cover, or a combination of conductive and non-conductive materials.

[0129] For example, the middle frame 310 may include a frame 311 and a middle plate 312. The frame 311 may be disposed around the middle plate 312 and connected to the middle plate 312. The frame 311 may be formed of a conductive material such as metal. In this case, the frame 311 is a metal frame. In some embodiments, the middle frame 310 may also include only the frame 311. The back cover 320 may be integrally formed with the frame 311, that is, the back cover 320 and the frame 311 are integrally formed.

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

[0131] In some embodiments, a metal layer may be provided on the circuit board 400. The metal layer may be used to ground the electronic components carried on the circuit board 400, or may be used to ground other components within the electronic device 1000 (e.g., a bracket antenna, a frame antenna, etc.). In this case, the metal layer may be referred to as a floor, a ground plane, or a grounding layer. For example, the edge of the circuit board 400 may be considered the edge of its floor.

[0132] In some embodiments, the conductive portion of the middle frame 310 and / or the back cover 320 can also serve as a reference ground for the electronic device 1000. Components such as circuit boards in the electronic device 1000 can be grounded by being electrically connected to the middle frame 310 and / or the back cover 320. In other embodiments, the electronic device 1000 may also have other ground planes, which will not be described in detail here.

[0133] FIG3 is a schematic structural diagram of the frame 311 of the electronic device 1000 shown in FIG2c.

[0134] As shown in Figure 3, 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 arranged opposite each other, and a first long side 3113 and a second long side 3114 arranged opposite each other. The first short side 3111 and the second short side 3112 can both be connected between the first long side 3113 and the second long side 3114. An angle (e.g., 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 the direction in which it extends. The length of the first short side 3111 refers to the dimension of the first short side 3111 in the direction in which it extends. 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 long strips. The frame 311 can also include multiple corners (not shown). 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 by a corner. In other embodiments, any corner of the frame 311 can also be considered as part of the long side or short side adjacent to the corner.

[0135] In this embodiment, when a user holds the electronic device 1000 (see FIG. 2 a ), the first short side 3111 may be located at the top of the electronic device 1000. The second short side 3112 may be located at the bottom of the electronic device 1000. The first long side 3113 may be located at the left side of the electronic device 1000. The second long side 3114 may be located at the right side of the electronic device 1000.

[0136] It should be noted that the frame 311 shown in Figure 3 is described using a non-foldable electronic device 1000 as an example. When the electronic device 1000 is a foldable electronic device 1000 (e.g., a multi-fold device such as a two-fold or three-fold device), the first long side 3113, the second long side 3114, the first short side 3111, and the second short side 3112 can be understood as the long and short sides of the portion of the frame corresponding to one of the multiple folds.

[0137] FIG4 is a partially enlarged schematic structural diagram of the structure shown in FIG3 .

[0138] As shown in FIG4 , 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 portion of the frame 311 of the electronic device 1000 as a main radiator and / or a parasitic branch. In one embodiment, the outer surface of the frame 311 may be a conductive material, such as a metal material, thereby forming the appearance of a metal frame, which is suitable for metal industrial design (ID). In these embodiments, the conductive portion of the frame 311 (e.g., including the outer surface of the frame 311) may be used as a radiator of the antenna device 500.

[0139] In one embodiment, the outer surface of the frame 311 can be made of a non-conductive material, such as plastic, creating a non-metallic frame appearance suitable for non-metallic IDs. The inner surface of the frame 311 can be made of a conductive material, such as a metal material. In these embodiments, the conductive portion of the frame 311 (e.g., including the inner surface of the frame 311) can serve as the radiator of the antenna device 500. It should be understood that the radiator (or the conductive material on the inner surface) disposed on the inner surface of the frame 311 is positioned in close proximity to the non-conductive material of the frame 311 to minimize the volume occupied by the radiator and position it closer to the exterior of the electronic device 1000, achieving better signal transmission. It should be noted that the antenna radiator being positioned in close proximity to the non-conductive material of the frame 11 means that the antenna radiator can be positioned closely to the inner surface of the non-conductive material, embedded within the non-conductive material, or positioned close to the inner surface of the non-conductive material, for example, with a small gap between the antenna radiator and the inner surface of the non-conductive material. It should be understood that both the conductive and non-conductive materials can be considered part of the frame 11. The antenna radiator provided by the non-conductive material close to the frame 11 can also become the frame radiator.

[0140] For example, the first short side 3111 may be provided with a first slit 311a and a second slit 311b. The first slit 311a and the second slit 311b may define a metal segment on the first short side 3111, forming the first frame radiator 510 of the antenna device 500. The first slit 311a and the second slit 311b may be filled with an insulating material, such as a polymer, glass, ceramic, or a combination thereof. In other embodiments, the material of the first short side 3111 may be a non-conductive material. In this case, the first short side 3111 may not be provided with the first slit 311a and the second slit 311b. The first frame radiator 510 may be a conductive object attached to the first short side 3111, such as an FPC antenna or an LDS antenna. In some embodiments, the width of the first slit 311a / the second slit 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 slits provided on the frame 311 may be within the aforementioned range. In some other embodiments, the first frame radiator 510 may also be disposed on the first long side 3113. The present application does not impose strict limitations on the specific location and form of the first frame radiator 510.

[0141] For example, 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. Specifically, the first end 511 may constitute the first open end of the first frame radiator 510, and the second end 512 may constitute the 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 grounded end.

[0142] For example, 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 stimulate the first frame radiator 510 to resonate.

[0143] Exemplarily, the first frame radiator 510 may include a first grounding point 513. The first frame radiator 510 may be coupled to the floor at the first grounding point 513. The floor may be a metal layer on the circuit board 400 and / or the middle frame 310 (please refer to FIG2c ). It should be understood that in the embodiment of the present application, the coupling connection is only illustrated by taking electrical connection as an example. In actual production or practice, it can also be achieved by indirect coupling. For the sake of simplicity, they will not be described one by one. In other embodiments, the first frame radiator 510 may also not include the first grounding point 513. FIG4 only illustrates the case where the first frame radiator 510 includes the first grounding point 513.

[0144] Exemplarily, the antenna assembly 500 can be used to receive or transmit signals in a communication frequency band used for satellite messaging and / or satellite telephony. The operating frequency band of the antenna assembly 500 can include a satellite communication frequency band. Satellite communications include at least one of satellite receiving and / or sending short messages (also known as short messages), satellite calling and / or receiving calls, and satellite data (e.g., internet access). That is, the first frame radiator 510 can be used to receive / transmit signals in a satellite communication frequency band. In this case, the first short side 3111 can be considered the top side of the electronic device 1000. The second short side 3112 can be considered the bottom side of the electronic device 1000. The first long side 3113 can be considered the first side side of the electronic device 1000. The second long side 3114 can be considered the second side side of the electronic device 1000. In other embodiments, the first frame radiator 510 can also be located on the first long side 3113. In this case, the first long side 3113 can be considered the top side of the electronic device 1000. The first short side 3111 and the second short side 3112 can be respectively regarded as the first side and the second side of the electronic device 1000. 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 part of the frequency band in the Tiantong satellite system, for example, the transmit frequency band (1980 MHz-2010 MHz) and the receive frequency band (2170 MHz-2200 MHz) in the Tiantong satellite system. In one embodiment, the satellite communication frequency band may include part of the frequency band in the Beidou satellite system, for example, the transmit frequency band (1610 MHz-1626.5 MHz) and the receive frequency band (2483.5 MHz-2500 MHz) in the Beidou satellite system. In one embodiment, the antenna device 500 may be a low-orbit satellite communication antenna. For example, the transmit frequency band of the low-orbit satellite communication antenna is 1668 MHz-1675 MHz, and the receive frequency band of the low-orbit satellite communication antenna is 1518 MHz-1525 MHz. Alternatively, the antenna device 500 may be a Beidou satellite communication antenna. For example, the transmit frequency band of the Beidou satellite communication antenna is 1615 MHz-1620 MHz, and the receive frequency band of the Beidou satellite communication antenna is 2480 MHz-2500 MHz. Alternatively, antenna device 500 may be a Tiantong satellite communication antenna or a high-orbit satellite communication antenna. For example, the transmit frequency band of the Tiantong satellite communication antenna is 1980 MHz to 2000 MHz, and the receive frequency band of the Tiantong satellite communication antenna is 2170 MHz to 2200 MHz. Alternatively, antenna device 500 may be a medium-orbit satellite communication antenna operating in the 4 GHz to 6 GHz frequency band. In other embodiments, antenna device 500 may also be applied to other satellite communication systems, and the embodiments of this application are not limited thereto.

[0146] For example, when the antenna device 500 operates in the Tiantong satellite system (i.e., the antenna's operating frequency band includes at least part of the frequency band in the Tiantong satellite system), the electronic device 1000 can perform voice communication via the antenna. In some embodiments, when the antenna device 500 operates in the Beidou satellite system (i.e., the antenna's operating frequency band includes at least part of the frequency band in the Beidou satellite system), the electronic device 1000 can send or receive short messages via the antenna device 500.

[0147] Figure 5 is a schematic diagram of the exploded structure of the camera decorative assembly 100 shown in Figure 2b in some embodiments. Figure 6 is a schematic diagram of the assembled structure of the camera decorative assembly 100, frame 311, and circuit board 400 of the electronic device 1000 shown in Figure 2a in some embodiments. Figure 7 is a schematic diagram of a partial cross-section of the electronic device 1000 shown in Figure 2b taken along line AA in one embodiment. For ease of understanding, the protective cover 20 of the camera decorative assembly 100 is hidden in Figure 6.

[0148] As shown in Figures 5 to 7, the electronic device 1000 may further include a camera decoration assembly 100 and a camera module 600 (Figure 3 also schematically illustrates the camera decoration assembly 100 and the camera module 600). The back cover 320 may be provided with a light-transmitting hole 321. The camera module 600 may be installed on the side of the middle frame 310 facing away from the screen 200. The light inlet of the camera module 600 may be exposed relative to the light-transmitting hole 321 of the back cover 320. The camera decoration assembly 100 may be fixed to the back cover 320. At least part of the camera decoration assembly 100 may cover the light-transmitting hole 321. In this embodiment, the camera decoration assembly 100 may be located in the middle position between the first side (i.e., the first long side 3113 in this embodiment) and the second side (i.e., the second long side 3114 in this embodiment), and is arranged close to the top edge (i.e., the first short side 3111 in this embodiment). That is, the camera decorative component 100 can be located at the upper middle portion of the rear cover 320 (see FIG. 2 b ). In other embodiments, the camera decorative component 100 can also be located closer to the second side relative to the first side.

[0149] Exemplarily, the camera decoration assembly 100 may include a decoration body 10 and a protective cover 20. The decoration body 10 may be roughly sheet-shaped or plate-shaped. The decoration body 10 may be fixedly connected to the back 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 part of the decoration body 10 may cover the avoidance hole of the back cover 320. The decoration body 10 may be arranged opposite the circuit board 400 and / or the middle plate 312 of the middle frame 310. In this embodiment, the decoration body 10 may be arranged opposite the circuit board 400.

[0150] Exemplarily, the decorative component body 10 may be provided with an avoidance hole 10a. The avoidance hole 10a may be arranged opposite to the light inlet of the camera module 600. Exemplarily, the number of camera modules 600 may be multiple. The number of avoidance holes 10a may also be multiple. Multiple avoidance holes 10a may be arranged one-to-one with respect to the light inlets of multiple camera modules 600. Among them, the shapes and sizes of the multiple avoidance holes 10a may be completely consistent. 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 exactly the same.

[0151] For example, the protective cover 20 can be located on the side of the decorative element body 10 facing away from the middle frame 310 and fixedly connected to the decorative element body 10 and / or the back cover 320. The material of the protective cover 20 can be glass, transparent plastic, or other light-transmitting materials.

[0152] For example, the decorative element body 10 may include a metal portion. The first radiator 30 may be formed at least partially of a metal portion. In this embodiment, the entire metal portion of the decorative element body 10 may be used to form the first radiator 30. In some embodiments, the decorative element body 10 may also include a non-metallic portion. The non-metallic portion may be connected to the metal portion. In some embodiments, a dielectric may be filled between the decorative element 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. The dielectric may be made of an insulating material such as plastic.

[0153] Fig. 8 is a schematic diagram of the assembly structure of the structure shown in Fig. 6 and the camera module 600 from another perspective. Fig. 9 is a schematic diagram of a partial cross-sectional structure of an embodiment of the electronic device 1000 shown in Fig. 2b taken along line BB.

[0154] As shown in Figures 7 to 9, the decorative element body 10 can be located midway between the first side (i.e., the first long side 3113 in this embodiment) and the second side (i.e., the second long side 3114 in this embodiment), that is, the decorative element body 10 can be centered along the length extension direction of the top side (i.e., the first short side 3111 in this embodiment). The distance between the first radiator 30, decorative element body 10, and the first side is the first distance. The distance between the decorative element body 10 and the second side is the second distance. For example, when the ratio of the first distance to the second distance is within the range of 0.8 to 1.2, the decorative element body 10 can be considered to be located midway 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 two end values ​​of 0.8 and 1.2.

[0155] For example, the first radiator 30 may include a first region 31 and a second region 32 connected to each other. 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, FIG8 illustrates the outline of the portion of the camera module 600 obscured by the first radiator 30 using a wider dashed line.

[0156] Exemplarily, the first radiator 30 may include a plurality of first grounding points 33 spaced apart. The plurality of first grounding points 33 may all be located in the first area 31. The camera decoration assembly 100 may further include a plurality of first grounding members 61 (the first grounding members 61 are illustrated by narrow dashed lines in FIG8 ). The first radiator 30 may be coupled to the floor through a plurality of first grounding members 61 at the plurality of first grounding points 33 in a one-to-one correspondence. In this 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 the directivity pattern of the first radiator 30 may also be adjusted by adjusting the relative positions between the plurality of first grounding points 33.

[0157] For example, the first radiator 30 may include a first feed point 34. The camera decorative assembly 100 may also include a first feed line 71 (the first feed line 71 is schematically illustrated by a narrow dashed line in FIG8 ). The first feed point 34 may be located in the first region 31. The first radiator 30 may be electrically connected to a first feed terminal (not shown) of the circuit board 400 at the first feed point 34 via the first feed line 71.

[0158] Exemplarily, the first frame radiator 510 of the electronic device 1000 can be used to operate in a first frequency band. The first radiator 30 can be used to support communications in the first frequency band, that is, the first frame radiator 510 and the first radiator 30 are of the same frequency. The first frame radiator 510 and the first radiator 30 can be electrically connected to the same RF chip (not shown). That is, the antenna device 500 can be electrically connected to the same RF chip through the first frame radiator 510 and the first radiator 30, thereby achieving an expanded directional pattern, or an expanded beam, or an expanded bandwidth to improve antenna performance. It should be understood that the same RF chip in the embodiments of the present application can refer to the same receiver (receiver) or the same transceiver (transeiver). In this way, the first frame radiator 510 and the first radiator 30 can serve as receiving antennas with the same function, and through diversity combination by the receiver or transceiver, the antenna performance can be improved. Among them, the first frequency band can correspond to the communication frequency band of satellite messaging and / or satellite phone, for example, the receiving frequency band of satellite messaging and / or satellite phone. At this time, the first radiator 30 and the first frame radiator 510 can be electrically connected to the same satellite communication chip / RF chip.

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

[0160] As shown in Figures 10 and 11 , the maximum radiation direction of the directional pattern generated by the first frame radiator of a typical electronic device can be from the bottom to the top of the electronic device. The first frame radiator can be configured to operate in a first frequency band. When radiating, the beam generated by the first frame radiator is relatively narrow (e.g., less than ±10°). In this embodiment, by providing the first radiator 30 within the camera decorative assembly 100, the first radiator 30 can be configured to support communications in the first frequency band. The first radiator 30 and the first frame radiator 510 operate at the same frequency. The first radiator 30 and the first frame radiator 510 can be electrically connected to the same RF chip. In this way, the first radiator 30 and the first frame radiator 510 can serve as receiving antennas with the same function and perform diversity synthesis using the same RF chip. When the first radiator 30 and the first frame radiator 510 operate simultaneously, the directional pattern generated by the first radiator 30 can complement the directional pattern generated by the first frame radiator 510. The beam generated by the first radiator 30 and the first frame radiator 510 together is relatively wide (e.g., greater than ±30°), thereby improving antenna performance.

[0161] Exemplarily, the first frequency band can be applied to the communication frequency band of satellite messaging and / or satellite telephony. For example, the first frequency band can correspond to the receiving frequency band of satellite messaging and / or satellite telephony. 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 messaging and / or satellite telephony. 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 be used only 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 messaging and / or satellite telephony. 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 is understood that the camera decorative assembly 100 in this embodiment may include a decorative body 10. The decorative body 10 may include a metal portion. At least a portion of the metal portion may be used to form a first radiator 30. The first radiator 30 may be used to support communication of the first frame radiator 510 in the first frequency band. That is, the first radiator 30 may be co-frequency with the first frame radiator 510. The first radiator 30 and the first frame radiator 510 are electrically connected to the same RF chip. Thus, the first radiator 30 and the first frame radiator 510 can be combined by diversity signaling using the same RF chip, thereby improving antenna performance. Furthermore, the first radiator 30 is formed from at least a portion of the metal portion of the decorative body 10. This metal portion of the decorative body 10 can achieve multiple uses, allowing the first radiator 30 to improve antenna performance without occupying the limited antenna layout space in the frame 311 of the electronic device 1000, thereby alleviating antenna layout pressure in the frame 311 of the electronic device 1000.

[0163] Secondly, the first frame radiator 510 can be located at the top edge, and the decorative member body 10 can be centered relative to the first and second side edges. The directivity pattern of the first radiator 30 can complement that of the first frame radiator 510. The first radiator 30 and the first frame radiator 510 can combine to form a wide beam, achieving an expanded directivity pattern and an expanded beam. This allows the radiation generated by the first radiator 30 and the first frame radiator 510 to have good transmission and reception capabilities in a wide range of directions.

[0164] Secondly, the first frequency band can be applied to the communication frequency band of satellite messaging and / or satellite phone calls. It should be understood that when a user conducts satellite communication, the antenna's maximum radiation direction needs to be pointed toward the satellite to achieve alignment (i.e., establish a communication connection with the satellite). When the antenna's beam is narrow (e.g., less than ±10°), the antenna's alignment requirements are high, and the attitude change of the electronic device 1000 has a greater impact on the quality of satellite communication. When the antenna's beam is wide (e.g., more than ±30°), the alignment requirements are low, and the attitude change of the electronic device 1000 has a smaller impact on the quality of satellite communication. 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 alignment requirements of the electronic device 1000 during satellite communication, thereby effectively reducing the impact of the attitude change of the electronic device 1000 on the quality of satellite communication, and 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 messaging and / or satellite phone calls. In this way, when a user uses electronic device 1000 to receive satellite signals, the reception sensitivity is higher, which helps enhance the signal reception capability of electronic device 1000 and improves 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. Thus, by setting up a multi-satellite antenna system, the user experience when using 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 may also function as a parasitic branch of the antenna device 500 to generate resonance, thereby improving the antenna performance of the antenna device 500.

[0166] In some embodiments, the camera decorative assembly 100 can be positioned closer to the first long side 3113 than the second long side 3114. A first frame radiator 510 can also be positioned on the first long side 3113. The first frequency band of the first frame radiator 510 can correspond to the Wi-Fi / Bluetooth communication frequency band. This allows the first radiator 30 to enhance the Wi-Fi / Bluetooth communication signal of the electronic device 1000, improving the user experience.

[0167] Please refer to Figures 5 to 7 again. The camera decoration assembly 100 may also 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 bonding or other means. The second radiator 40 may be located between the decoration body 10 and the protective cover 20. The second radiator 40 may be spaced apart from the first feeding point 34 and the multiple first grounding points 33 of the first radiator 30. The second radiator 40 may also be spaced apart from the multiple avoidance holes 10a of the decoration body 10. 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] For example, the second radiator 40 may include a second feeding point 41. The second feeding point 41 may be electrically connected to a second feeding terminal (not shown) on the circuit board 400 at the second feeding point 41. The second radiator 40 may be electrically connected to the second feeding terminal on the circuit board 400 at the second feeding point 41 by passing through the decorative element body 10 via an electrical connector such as a lead. In other embodiments, the decorative element body 10 may further be provided with a connecting hole. The second radiator 40 may also be electrically connected to the second feeding terminal on the circuit board 400 at the second feeding point 41 via an electrical connector such as a lead through the connecting hole on the decorative element body 10.

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

[0170] Exemplarily, the camera decorative assembly 100 may further include an isolation layer (not shown). 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 nanocrystal. In this way, the isolation layer may exhibit magnetic conductor properties at low frequencies (for example, in the operating frequency band of the second radiator 40), and the isolation layer may exhibit electrical conductor properties with low conductivity at high frequencies (for example, in the first frequency band) to avoid resonance between the second radiator 40 and the first radiator 30, thereby achieving better isolation between the second radiator 40 and the first radiator 30.

[0171] It is understood that the camera decorative assembly 100 in this embodiment may include a first radiator 30 and a second radiator 40. The first radiator 30 may be formed from at least a portion of the metal portion of the decorative component 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 may be arranged in close proximity to the first radiator 30, and the two may reuse the space of the camera decorative assembly 100, thereby improving antenna performance without occupying the limited antenna layout space in the frame 311 of the electronic device 1000, which helps to relieve the antenna layout pressure of the frame 311 of the electronic device 1000.

[0172] FIG12 is a schematic diagram of an enlarged structure of the structure shown in FIG6 at position C. FIG.

[0173] As shown in Figures 9 and 12, the camera decoration assembly 100 may further include a third radiator 50 (the third radiator 50 is also illustrated in Figures 5 and 6). 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 assembly 100 may further include a bracket (not shown). The third radiator 50 may be fixed in the groove 35 of the first radiator 30 by the bracket. The third radiator 50 may be suspended relative to the bottom wall 351 of the groove 35. The bracket may be an insulator for supporting the third radiator 50. For example, the bracket may be a plastic bracket. The third radiator 50 may be provided (for example, printed / imprinted) on the upper surface or 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. The height of the third radiator 50 may be the distance between the upper surface of the third radiator 50 (ie, the surface of the third radiator 50 facing the opening of the groove 35 ) and the bottom wall 351 of the groove 35 .

[0174] For example, the third radiator 50 may be a sheet radiator. In one embodiment, the length of the third radiator 50 may be less than five times its width. 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 third radiator 50 is irregular in shape, the length and width of the third radiator 50 may be the length and width of the rectangle enclosed by the outer contour of the third radiator 50. In this case, the ratio of the area of ​​the third radiator 50 to the area of ​​the rectangle enclosed by the outer contour of the third radiator 50 may be greater than 1. For ease 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. The second direction may be parallel to the Y-axis.

[0175] For example, 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 the portion of the third radiator 50 where the third grounding point 53 is located, or in other words, the portion of the third radiator 50 that is grounded. The camera decorative assembly 100 may also include a second grounding member 72. The third radiator 50 may be electrically connected to the first radiator 30 at the third grounding point 53 via the second grounding member 72. In this case, the first radiator 30 may serve as a reference ground for the third radiator 50. It should be understood that because the third radiator 50 is smaller than the first radiator 30, the fundamental mode frequency band of the third radiator 50 may be higher than the fundamental mode frequency band of the first radiator 30, allowing the first radiator 30 to serve as a reference ground for 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 grounded, and the second end 52 of the third radiator 50 may be open. Current from the third radiator 50 may flow into the first radiator 30 via the first grounding point 33. For example, 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 (eg, three). The multiple third grounding points 53 may be spaced apart along the second direction.

[0176] For example, 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 also be provided with a through hole 352. The camera decorative assembly 100 may also include a second feed line 62. The third radiator 50 may be electrically connected to the feeding point end of the circuit board 400 at the third feeding point 54 via the second feed line 62. The second feed line 62 may pass through the through hole 352 of the first radiator 30.

[0177] In some embodiments, the camera decorative assembly 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 portion of the feeder grounding member 73 may be located within the through-hole 352. This allows the feeder grounding member 73 to adjust the impedance of the third feeding point 54 of the third radiator 50, improving antenna performance. In one embodiment, the feeder grounding member 73 may be hollow. The second feeder 62 may be threaded within the feeder grounding member 73. The feeder grounding member 73 may wrap around a portion of the second feeder 62. The second feeder 62 and the feeder grounding member 73 may be coaxial. In this case, the second feeder 62 may serve as the inner core of the coaxial structure, and the feeder grounding member 73 may serve as the outer core of the coaxial structure. In another embodiment, the feeder grounding member 73 may be solid. The feeder grounding member 73 may be located on one side of the second feeder 62. Alternatively, there may be two feeder grounding members 73. The second feeder 62 may be located between the two feeder grounding members 73 and spaced apart from the two feeder grounding members 73 .

[0178] 13 is a schematic diagram of S11 simulation curves of the first radiator 30 and the third radiator 50 shown in FIG6 . It should be noted that curve 1 in FIG13 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 shown in Figure 13, the first radiator 30 can generate multiple resonances based on the fundamental mode and higher-order modes. The resonance generated by the first radiator 30 based on the fundamental mode is the first resonance. The first radiator 30 can operate in multiple resonant frequency bands. The third radiator 50 can generate a single resonance based on the fundamental mode, namely the second resonance. The frequency band of the first resonance can be lower than the frequency band of the second resonance.

[0180] It is understood that the camera decorative assembly 100 in this embodiment may further include a third radiator 50, which may be at least partially disposed within the groove 35 of the first radiator 30. In this way, the first radiator 30 and the third radiator 50 may reuse the space of the camera decorative assembly 100, thereby improving antenna performance without occupying the limited antenna layout space in the frame 311 of the electronic device 1000, thereby relieving the antenna layout pressure in the frame 311 of the electronic device 1000.

[0181] Fig. 14 is a schematic diagram of the structure of another embodiment of the camera decoration assembly 100 shown in Fig. 12. Fig. 15 is a schematic diagram of the S11 simulation curve of the third radiator 50 and the fourth radiator 80 shown in Fig. 14.

[0182] As shown in Figures 14 and 15, the structure of the camera decorative assembly 100 in this embodiment is substantially the same as that of the camera decorative assembly 100 shown in Figure 12, and the identical parts are not repeated here. The differences between the two are described below. For example, the first end 51 of the third radiator 50 may be provided with a third grounding point 53. The camera decorative assembly 100 may also 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 within the groove 35 of the first radiator 30 by a bracket and spaced apart from the third radiator 50. The fourth radiator 80 may be at least partially housed within the groove 35. The fourth radiator 80 may be suspended relative to the bottom wall 351 of the groove 35. For example, the fourth radiator 80 may be a sheet-shaped radiator. The shape and size of the fourth radiator 80 may be the same as those of the third radiator 50.

[0183] For example, the fourth radiator 80 may include a first end 81 and a second end 82. The first end 81 of the fourth radiator 80 may be the fourth grounding point 83 provided on the fourth radiator 80, or the grounded portion of the fourth radiator 80. The camera decorative assembly 100 may further include a third grounding member 74. The fourth radiator 80 may be electrically connected to the first radiator 30 at the fourth grounding point 83 via the third grounding member 74. In this case, the first radiator 30 may also serve as a reference ground for the fourth radiator 80. The second end 82 of the fourth radiator 80 is not grounded. The first end 81 of the fourth radiator 80 is a grounded end, and the second end 82 of the fourth radiator 80 is an open end. The first end 81 of the fourth radiator 80 may be disposed opposite the second end 52 of the third radiator 50. The second end 82 of the fourth radiator 80 may be disposed opposite the first end 51 of the third radiator 50. In other words, the grounded end of the fourth radiator 80 may be disposed opposite the open end of the third radiator 50. The open end of the fourth radiator 80 may be disposed opposite to the ground end of the third radiator 50 .

[0184] For example, the fourth radiator 80 can generate related resonance by coupling energy from the third radiator 50. In this case, the third radiator 50 and the fourth radiator 80 can form a composite antenna, operating in two consecutive resonant frequency bands, achieving broadband coverage. It should be understood that when the ratio between the two frequencies corresponding to two resonant points is in the range of 1:1 to 1:1.2, the two resonant frequency bands containing the two resonant points can be considered continuous. The third radiator 50 can serve as the primary radiator, and the fourth radiator 80 can serve as a parasitic radiator.

[0185] It can be understood that in this embodiment, a composite antenna is formed by arranging the fourth radiator 80 and the third radiator 50 in the groove 35. Among them, the third radiator 50 can serve as a main radiator, and the fourth radiator 80 can serve as a parasitic radiator. In this way, the composite antenna formed by the third radiator 50 and the fourth radiator 80 can generate two resonant frequency bands, and the two resonant frequency bands are continuous, which is conducive 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 decorative component 100, thereby improving the antenna performance without occupying the limited antenna layout space in the frame 311 of the electronic device 1000, which is conducive to relieving the antenna layout pressure of the frame 311 of the electronic device 1000.

[0186] FIG16 is a schematic diagram of another embodiment of the structure shown in FIG12 . FIG17 is a schematic diagram of an S11 simulation curve of the third radiator 50 shown in FIG16 . It should be noted that Curve 1 in FIG17 is an S11 simulation curve of radiation generated by the first current on the third radiator 50, and Curve 2 is an S11 simulation curve of radiation generated by the second current on the third radiator 50.

[0187] As shown in Figures 16 and 17, the structure of the camera decorative assembly 100 in this embodiment is substantially the same as that of the camera decorative assembly 100 shown in Figure 12, and the identical parts are not repeated here. The differences between the two are described below. For example, the third radiator 50 may further include a fourth feed 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 feed point 54 may be located at the first end 51 of the third radiator 50, and disposed near the third end 56. For example, the first third feed point 54 may be located at a corner position between the first end 51 and the third end 56. The fourth feed point 55 may be located at the first end 51, and between the third end 56 and the fourth end 57. For example, the fourth feed point 55 may be located midway between the third end 56 and the fourth end 57. That is, the distance from the fourth feed point 55 to the third end 56 may be equal to the distance from the fourth feed point 55 to the fourth end 57.

[0188] For example, the number of through holes 352 in the groove 35 can be two. The number of second feed lines 62 can also be two. One feed line 62 can pass through one of the through holes 352 and respectively connect the third feed point 54 and the third feed terminal (not shown) of the circuit board 400. The other feed line 62 can pass through the other through hole 352 and respectively connect the fourth feed point 55 and the fourth feed terminal (not shown) of the circuit board 400 (please refer to Figure 9).

[0189] For example, the third radiator 50 may have two third grounding points 53. One of the third grounding points 53 may be located between the third feeding point 54 and the fourth feeding point 55. The other third grounding point 53 may be located on a side of the fourth feeding point 55 facing away from the third feeding point 54.

[0190] Exemplarily, when the third radiator 50 is working, the third feeding point 54 can excite a first current along a first direction on the third radiator 50, and the fourth feeding point 55 can excite a second current along a second direction on the third radiator 50. The first current can be orthogonal to the second current. That is, 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 common radiator by the excitation of the transverse and longitudinal modes, and operate in two resonant frequency bands. The isolation between the two antennas of the common radiator is relatively high (for example, the isolation is below 15). In one embodiment, one of the resonant frequency bands can cover the N77 frequency band (3.3GHz-4.2GHz). The other resonant frequency band can cover the WIFI 5G frequency band (5.15GHz-5.875GHz).

[0191] It can be understood that the third radiator 50 in this embodiment includes a third feeding point 54 and a fourth feeding point 55. The third feeding point 54 and the fourth feeding point 55 can both be located at the first end 51 of the third radiator 50. The third feeding point 54 can be located near 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 along a first direction and a second current along a second direction on the third radiator 50. The first current is orthogonal to the second current. That is, 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. By exciting the transverse and longitudinal modes, the third radiator 50 can be expanded into a dual-antenna structure of a common radiator to improve the antenna performance of the electronic device 1000.

[0192] In some embodiments, the second end 52 of the third radiator 50 may further include at least one notch 58. The notch 58 may be substantially in the shape of an elongated strip. Thus, by providing the notch 58 at the second end 52, the electrical length of the third radiator 50 in the first direction may be increased, allowing the third radiator 50 to support resonance at a lower frequency band, thereby improving antenna performance.

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

[0194] It should be noted that, in the absence of conflict, the features in the embodiments of this application can be combined with each other, and any combination of features in different embodiments is also within the scope of protection of this application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0195] It should be noted that all the above drawings are illustrative illustrations of this application and do not represent the actual size of the product. The dimensional ratio relationship between the components in the drawings does not serve as a limitation on the actual product of this application. The above are only some of the implementation methods of this application. The scope of protection of this application is not limited to this. Any person skilled in the art who is familiar with the technical scope disclosed in this application can easily think of changes or replacements, which should be covered by the scope of protection of this application.
