Description

Technical Field

[0001] This application relates to the field of wireless communication, and more particularly to an electronic device. Background Technology

[0002] Currently, existing terminal electronic devices utilize the frame as an antenna radiator. For example, in satellite navigation or satellite communication systems, the frame radiator is mainly used to form a linearly polarized antenna. When users perform satellite navigation or satellite communication, the antenna's maximum radiation direction needs to be pointed towards the satellite to achieve alignment (establish a communication connection with the satellite). However, the linearly polarized antenna formed by the frame radiator has its maximum radiation direction perpendicular to the electronic device's display screen. Users need to face the screen towards the sky when performing satellite navigation or communication, which causes significant inconvenience. Summary of the Invention

[0088] The following explains the terms that may appear in the embodiments of this application.

[0089] It should be understood that the term "and / or" used in this document is merely a description of the same field in the related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0090] The phrase "within the range" used in this application, unless otherwise specified, includes both endpoints of the range by default. For example, in the range of 1 to 5, it includes the values ​​1 and 5.

[0091] Coupling can be understood as direct coupling and / or indirect coupling. "Coupled connection" can be understood as a direct coupling connection and / or indirect coupling connection. Direct coupling can also be called "electrical connection," which can be understood as physical contact and electrical conduction between components; it can also be understood as the form of connection between different components in a circuit structure through physical lines that can transmit electrical signals, such as copper foil or wires on a printed circuit board (PCB). "Indirect coupling" can be understood as electrical conduction between two conductors through a gap / non-contact method. In one embodiment, indirect coupling can also be called capacitive coupling, for example, signal transmission is achieved by forming an equivalent capacitance through coupling between the gaps between two conductive parts.

[0092] Components / devices: including at least one of lumped components / devices and distributed components / devices.

[0093] Lumped element / device: This refers to all components whose size is much smaller than the wavelength relative to the circuit's operating frequency. For signals, the characteristics of the components remain constant at all times, regardless of frequency.

[0094] Distributed elements / devices: Unlike lumped elements, if the size of an element is similar to or larger than the wavelength of the circuit's operating frequency, then when a signal passes through the element, the characteristics of each point on the element will vary due to the signal change. In this case, the element as a whole cannot be regarded as a single entity with fixed characteristics, but should be called a distributed element.

[0095] Capacitor: can be understood as lumped capacitance and / or distributed capacitance. Lumped capacitance refers to capacitive components, such as capacitor elements; distributed capacitance (or distributed capacitance) refers to the equivalent capacitance formed by two conductive components separated by a certain gap.

[0096] Inductance: can be understood as lumped inductance and / or distributed inductance. Lumped inductance refers to inductive components, such as inductor elements; distributed inductance (or distributed inductance) refers to the equivalent inductance formed through a conductive element of a certain length.

[0097] Radiator: In an antenna, this is the device used to receive / transmit electromagnetic wave radiation. In some cases, the term "antenna" is narrowly defined as a radiator, which converts guided wave energy from the transmitter into radio waves, or converts radio waves into guided wave energy, for radiating and receiving radio waves. The modulated high-frequency current energy (or guided wave energy) generated by the transmitter is transmitted to the transmitting radiator via a feed line, where it is converted into electromagnetic wave energy of a specific polarization and radiated in the desired direction. The receiving radiator converts the electromagnetic wave energy of a specific polarization from a specific direction in space back into modulated high-frequency current energy, which is then transmitted to the receiver input via a feed line.

[0098] The radiator may include a conductor with a specific shape and size, such as a wire or sheet, and this application does not limit the specific shape. In one embodiment, the wire radiator may be simply referred to as a wire antenna. In one embodiment, the wire radiator may be implemented by a conductive frame, and may also be referred to as a frame antenna. In one embodiment, the wire radiator may be implemented by a support conductor, and may also be referred to as a support antenna. In one embodiment, the wire diameter (e.g., including thickness and width) of the wire radiator, or the radiator of the wire antenna, is much smaller than the wavelength (e.g., the wavelength of the medium) (e.g., less than 1 / 16 of the wavelength), and the length may be comparable to the wavelength (e.g., the wavelength of the medium) (e.g., the length is around 1 / 8 of the wavelength, or 1 / 8 to 1 / 4, or 1 / 4 to 1 / 2, or longer). The main forms of wire antennas include dipole antennas, half-wave dipole antennas, monopole antennas, loop antennas, and inverted F antennas (also known as IFA, Inverted F Antenna). For example, in a dipole antenna, each dipole antenna typically includes two radiating stubs, each fed from the feed end of the radiating stub by a feed section. For example, an IFA can be considered as a monopole antenna with an added ground path. An IFA has one feed point and one ground point, and is called an inverted-F antenna because its side view is inverted-F shaped. 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). In one embodiment, the sheet radiator may be implemented using a planar conductor (e.g., a conductive sheet or conductive coating). In one embodiment, the sheet radiator may include a conductive sheet, such as a copper sheet. In one embodiment, the sheet radiator may include a conductive coating, such as silver paste. The shape of the sheet radiator includes circular, rectangular, and annular shapes, and this application does not limit the specific shape. The structure of a microstrip antenna generally consists of a dielectric substrate, a radiator, and a ground plane, wherein the dielectric substrate is disposed between the radiator and the ground plane.

[0099] Radiators may also include slots or gaps formed on a conductor, for example, closed or semi-closed slots or gaps formed on a grounded conductor surface. In one embodiment, a slotted or slit radiator may be simply referred to as a slot antenna or a gap antenna. In one embodiment, the radial dimension (e.g., including width) of the slot or gap of the slot antenna / gap antenna is much smaller than the wavelength (e.g., the dielectric wavelength) (e.g., less than 1 / 16 of the wavelength), while the length dimension may be comparable to the wavelength (e.g., the dielectric wavelength) (e.g., a length of 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 gap may be simply referred to as a closed slot antenna. In one embodiment, a radiator with a semi-closed slot or gap (e.g., an opening added to a closed slot or gap) may be simply referred to as an open slot antenna. In some embodiments, the gap shape is elongated. In some embodiments, the length of the gap is approximately half a wavelength (e.g., the dielectric wavelength). In some embodiments, the length of the gap is approximately an integer multiple of a wavelength (e.g., one dielectric wavelength). In some embodiments, the slot can be fed by transmission lines connected across one or both sides, thereby exciting a radio frequency electromagnetic field on the slot and radiating electromagnetic waves into space. In one embodiment, the radiator of the slot antenna or gap antenna can be implemented by a conductive frame grounded at both ends, also known as a frame antenna; in this embodiment, the slot antenna or gap antenna can be viewed as including a linear radiator, the linear radiator being spaced apart from the ground and grounded at both ends, thereby forming a closed or semi-closed slot or gap. In one embodiment, the radiator of the slot antenna or gap antenna can be implemented by a support conductor grounded at both ends, also known as a support antenna.

[0100] A power supply circuit is a combination of all circuits used for receiving and transmitting radio frequency (RF) signals. It can include a transceiver and an RF front-end. In some cases, the term "power supply circuit" is narrowly interpreted as an RF IC (Radio Frequency Integrated Circuit), which can be considered to include both the RF front-end chip and the transceiver. The power supply circuit has the function of converting radio waves (e.g., RF signals) into electrical signals (e.g., digital signals). It is generally considered part of the RF component.

[0101] 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 to test the characteristics of the RF front-end circuitry or the radiator of the antenna. The RF front-end circuitry can be considered as the circuitry coupled between the test socket and the transceiver.

[0102] In some embodiments, the radio frequency front-end circuit can be integrated into a radio frequency front-end chip in an electronic device, or the radio frequency front-end circuit and the transceiver can be integrated into a radio frequency chip in an electronic device.

[0103] It should be understood that any two feed circuits in the first / second / ...Nth feed circuit of this application can share the same transceiver, for example, by transmitting signals through a radio frequency channel (e.g., a port (pin) of a radio frequency chip) in a transceiver; they can also share a radio frequency front-end circuit, for example, by processing signals through a tuning circuit or amplifier in a radio frequency front-end.

[0104] It should also be understood that the two feed circuits in the first / second / ...Nth feed circuit of this application typically correspond to two RF test sockets in an electronic device.

[0105] 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 mount 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, which may be electronic components for switching the coupling connection of the radiator. The matching circuit has impedance matching and / or frequency tuning functions. It is typically considered part of the antenna.

[0106] The grounding / feeding structure may include connectors, such as metal springs, and the radiator is coupled to the ground / feeding circuit via the grounding structure. In some embodiments, the feeding structure may include a transmission line / feeding wire, and the grounding structure may include a grounding wire.

[0107] End / Point: The term "end / point" in the context of the antenna radiator's first end / second end / feed end / ground end / feed point / ground point / connection point should not be narrowly interpreted as necessarily an endpoint or end physically disconnected from other radiators. It can also be considered a point or segment on a continuous radiator. In one embodiment, "end / point" can include a connection / coupling region on the antenna radiator that couples to other conductive structures. For example, a feed end / feed point can be a coupling region on the antenna radiator that couples to a feed structure or feed circuit (e.g., a region facing a part of the feed circuit). Similarly, a ground end / ground point can be a connection / coupling region on the antenna radiator that couples to a ground structure or ground circuit.

[0108] Open terminal, closed terminal: In some embodiments, open terminal and closed terminal are, for example, relative to whether or not they are grounded; the closed terminal is grounded, and the open terminal is not grounded. In some embodiments, open terminal and closed terminal are, for example, relative to other conductors; the closed terminal is electrically connected to other conductors, and the open terminal is not electrically connected to other conductors. In one embodiment, the open terminal may also be referred to as a floating terminal, free terminal, open terminal, or open-circuit terminal. In one embodiment, the closed terminal may also be referred to as a ground terminal or short-circuit terminal. It should be understood that in some embodiments, other conductors can be coupled through the open terminal to transfer coupled energy (which can be understood as transferring current).

[0109] In some embodiments, the understanding of "closed end" can also be from the perspective of current distribution. A closed end or ground end can be understood as a point of high current or low electric field on a radiator. In one embodiment, coupling electronic devices (e.g., capacitors, inductors, etc.) through a closed end can maintain the current distribution characteristics of the point of high current / low electric field. In one embodiment, opening a slit at or near the closed end (e.g., filling the slit with insulating material) can maintain the current distribution characteristics of the point of high current / low electric field.

[0110] In some embodiments, the understanding of "open terminal" can also be from the perspective of current distribution. An open terminal or a floating terminal can be understood as a point with a small current or a point with a large electric field on the radiator. In one embodiment, coupling electronic devices (e.g., capacitors, inductors, etc.) through an open terminal can maintain the current distribution characteristics of the point with a small current or a large electric field.

[0111] It should be understood that when an electronic device (e.g., capacitor, inductor, etc.) is coupled at the radiator end of a gap (which, from the perspective of the radiator's structure, is similar to the radiator at the opening of an open or floating end), the radiator end can be a point with a large current / small 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.

[0112] The "floating radiator" mentioned in the embodiments of this application refers to a radiator that is not directly connected to the feed line / feed branch and / or ground line / ground branch, but is fed and / or grounded through indirect coupling.

[0113] It should be understood that "suspended" in "suspended end" or "suspended radiator" does not mean that there is no structure around the radiator to support it. In one embodiment, the suspended radiator may be, for example, a radiator disposed on the inner surface of an insulating back cover.

[0114] The current in the same direction / opposite direction mentioned in the embodiments of this application should be understood as the main current on the same side of the conductor being in the same direction / opposite direction. For example, when a current distributed in the same direction is excited on a conductor that is bent or looped (e.g., the current path is also bent or looped), it should be understood that, for example, the main current excited on the conductors on both sides of a looped conductor (e.g., on the conductors on both sides of a gap) is opposite in direction, but it still falls under the definition of current distributed in the same direction in the embodiments of this application. In one embodiment, current in the same direction on a conductor can mean that the current on the conductor has no reverse point. In one embodiment, current in opposite direction on a conductor can mean that the current on the conductor has at least one reverse point. In one embodiment, current in the same direction on two conductors can mean that the current on both conductors has no reverse point and flows in the same direction. In one embodiment, current in opposite direction on two conductors can mean that the current on both conductors has no reverse point and flows in opposite directions. Current in the same direction / opposite direction on multiple conductors can be understood accordingly.

[0115] The "same direction / opposite direction" of electric fields mentioned in the embodiments of this application should be understood as the direction of the main electric field generated by the conductor in space (e.g., the electric field between the conductor and the ground) being the same direction / opposite direction. For example, when a unidirectionally distributed electric field is excited on a conductor that is bent or ring-shaped (e.g., the gap formed between the ground and the conductor is also bent or ring-shaped), it should be understood that, for example, the direction of the electric field in the gap is from the ground to the conductor, or from the conductor to the ground. Although the main electric field excited in the gaps on both sides of the ring-shaped conductor (e.g., the gaps on both sides of the gap surrounding a slit) is opposite in direction, it still falls under the definition of a unidirectionally distributed electric field in the embodiments of this application. In one embodiment, a unidirectional electric field between a conductor and the ground can mean that the electric field between the conductor and the ground has no opposite point. In one embodiment, an opposite electric field between a conductor and the ground can mean that the electric field between the conductor and the ground has at least one opposite point. In one embodiment, a unidirectional electric field between two conductors and the ground can mean that the electric fields between the two conductors and the ground have no opposite points and radiate in the same direction (e.g., the positive z-axis). In one embodiment, the opposite electric fields between two conductors and the ground can mean that the electric fields between the two conductors and the ground have no point of reversal and flow in opposite directions. Correspondingly, the same / opposite electric fields between multiple conductors and the ground can be understood.

[0116] Resonance / Resonant Frequency: The resonant frequency is also called the resonance frequency. The resonant frequency can have a frequency range, that is, the frequency range in which resonance occurs. The frequency corresponding to the strongest resonance point is the center frequency. The return loss characteristic of the center frequency can be less than -20dB. It should be understood that, unless otherwise specified, when the antenna / radiator mentioned in this application generates "first / second...resonance," 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 a specific design, and each antenna mode can correspond to a fundamental mode resonance.

[0117] Resonant frequency band: The range of resonant frequencies is the resonant frequency band. The return loss characteristics at any frequency point within the resonant frequency band can be less than -6dB or -5dB.

[0118] Communication band / operating band: Regardless of the type of antenna, it always operates within a certain frequency range (bandwidth). For example, an antenna supporting the B40 band operates within the frequency range of 2300MHz to 2400MHz, or in other words, the antenna's operating band includes the B40 band. The frequency range that meets the specifications can be considered the antenna's operating band.

[0119] The resonant frequency band and the operating frequency band can be the same or can partially overlap. In one embodiment, one or more resonant frequency bands of the antenna can cover one or more operating frequency bands of the antenna.

[0120] Electrical length: can be the ratio of physical length (i.e., mechanical length or geometric length) to the wavelength of the transmitted electromagnetic wave. Electrical length can satisfy the following formula:

[0121]

[0122] Where L is the physical length and λ is the wavelength of the electromagnetic wave.

[0123] Wavelength: or operating wavelength, 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, assuming the center frequency of the B1 uplink band (resonant frequency from 1920MHz to 1980MHz) is 1955MHz, then the operating wavelength can be the wavelength calculated using this frequency. Not limited to the center frequency, "operating wavelength" can also refer to the wavelength corresponding to the non-center frequency of the resonant frequency or operating frequency band.

[0124] It should be understood that the wavelength of a radiation signal in air can be calculated as follows: (air wavelength, or vacuum wavelength) = speed of light / frequency, where the frequency is the frequency of the radiation signal (MHz), and the speed of light can be taken as 3 × 10⁸ m / s. The wavelength of a radiation signal in a medium can be calculated as follows: Where ε is the relative permittivity of the medium. The wavelength in the embodiments of this application typically refers to the medium wavelength, which can be the medium wavelength corresponding to the center frequency of the resonant frequency, or the medium wavelength corresponding to the center frequency of the operating frequency band supported by the antenna. For example, assuming the center frequency of the B1 uplink band (resonant frequency of 1920MHz to 1980MHz) is 1955MHz, then the wavelength can be the medium wavelength calculated using this frequency. Not limited to the center frequency, the "medium wavelength" can also refer to the medium wavelength corresponding to the non-center frequency of the resonant frequency or operating frequency band. For ease of understanding, the medium wavelength mentioned in the embodiments of this application can be simply calculated using the relative permittivity of the medium filling one or more sides of the radiator.

[0125] Antenna system efficiency (total efficiency): refers to the ratio of input power to output power at the antenna port.

[0126] Antenna radiation efficiency refers to the ratio of the power radiated into space by an antenna (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 - loss power; loss power mainly includes return loss power and ohmic loss power of metals and / or dielectric loss power. Radiation efficiency is a measure of an antenna's radiation capability; metal loss and dielectric loss are both factors affecting radiation efficiency.

[0127] Those skilled in the art will understand that efficiency is generally expressed as a percentage, and there is a corresponding conversion relationship between it and dB. The closer the efficiency is to 0dB, the better the efficiency of the antenna.

[0128] Antenna radiation pattern: also known as radiation pattern. It refers to the graph showing the relative field strength (normalized modulus) of the antenna's radiated field as a function of direction at a certain distance from the antenna (far field). It is usually represented by two mutually perpendicular planar radiation patterns passing through the direction of maximum radiation of the antenna.

[0129] Antenna radiation patterns typically have multiple radiating beams. The beam with the highest radiating intensity is called the main lobe, and the remaining beams are called side lobes. Among the side lobes, the side lobe in the opposite direction to the main lobe is also called the back lobe.

[0130] Directivity: Also known as the antenna's directivity. It refers to the ratio of the maximum power density to the average power density on the antenna's radiation pattern at a certain distance from the antenna (far field), and is a dimensionless ratio greater than or equal to 1. It can be used to indicate the energy radiation characteristics of an antenna. The larger the directivity, the more energy the antenna radiates in a particular direction, and the more concentrated the energy radiation is.

[0131] Antenna gain: Characterizes the degree to which an antenna concentrates the radiated input power. Generally, the narrower the main lobe and the smaller the side lobes of the antenna pattern, the higher the antenna gain.

[0132] Antenna polarization: At a given point in space, the electric field intensity E (vector) is a function of time t. As time progresses, the endpoint of the vector periodically traces a trajectory in space. If this trajectory is a straight line and perpendicular to the ground, it is called vertical polarization; if it is horizontal to the ground, it is called horizontal polarization. If the trajectory is elliptical or circular, and when viewed along the propagation direction, it rotates clockwise or right-handed with time, it is called right-hand circular polarization (RHCP); if it rotates counterclockwise or left-handed with time, it is called left-hand circular polarization (LHCP).

[0133] Axial ratio (AR) of an antenna: In circular polarization, the trajectory traced periodically by the endpoints of the electric field vector in space is an ellipse. The ratio of the major axis to the minor axis of the ellipse is called the axial ratio. The axial ratio is an important performance indicator of a circularly polarized antenna. It represents the purity of circular polarization and is an important indicator for measuring the difference in signal gain of the entire antenna in different directions. The closer the axial ratio of the antenna is to 1 (the trajectory traced periodically by the endpoints of the electric field vector in space is a circle), the better its circular polarization performance.

[0134] Antenna return loss: This can be understood as the ratio of the signal power reflected back to the antenna port after passing through the antenna circuit to the transmit power at the antenna port. The smaller the reflected signal, the larger the signal radiated into space through the antenna, and the higher the antenna's radiation efficiency. Conversely, the larger the reflected signal, the smaller the signal radiated into space through the antenna, and the lower the antenna's radiation efficiency.

[0135] Antenna return loss can be represented by the S11 parameter, which is one of the S-parameters. S11 represents the reflection coefficient, and this parameter characterizes the antenna's transmission efficiency. The S11 parameter is usually negative. The smaller the S11 parameter, the smaller the antenna return loss, the less energy the antenna reflects back, which means more energy actually enters the antenna, and the higher the antenna's system efficiency. Conversely, the larger the S11 parameter, the greater the antenna return loss, and the lower the antenna's system efficiency.

[0136] It should be noted that in engineering, an S11 value of -6dB is generally used as the standard. When the S11 value of an antenna is less than -6dB, it can be considered that the antenna can work normally or that the antenna has good transmission efficiency.

[0137] Specific absorption rate (SAR): This is a unit of measurement for how much radio frequency radiation energy is actually absorbed by the body. It is expressed in watts per kilogram (W / kg) or milliwatts per gram (mW / g). The precise definition of SAR is: the derivative of energy (dw) absorbed per unit volume (dv) of a given material density (ρ—human tissue density) with respect to time.

[0138] Currently, there are two internationally accepted standards: the European standard of 2w / kg and the American standard of 1.6w / kg. The European standard specifically means that, based on a 6-minute timer, the electromagnetic radiation energy absorbed by each kilogram of human tissue must not exceed 2 watts.

[0139] Ground (GND): Generally refers to at least a portion of any grounding layer, ground plane, or grounding metal layer within an electronic device (such as a mobile phone), or at least a portion of any combination of the aforementioned grounding layers, ground planes, or grounding components. "Ground" can be used for grounding components within an electronic device. In one embodiment, "ground" can be the grounding layer of a circuit board in an electronic device, or a grounding metal layer formed by a ground plane formed within the frame of the electronic device or a metal film formed beneath the screen. In one embodiment, the circuit board can be a printed circuit board (PCB), such as an 8-layer, 10-layer, or 12-14-layer board having 8, 10, 12, 13, or 14 layers of conductive material, or components separated and electrically insulated by dielectric or insulating layers such as fiberglass or polymers. In one embodiment, the circuit board includes a dielectric substrate, a grounding layer, and a trace layer, with the trace layer and grounding layer electrically connected via vias. In one embodiment, components such as displays, touchscreens, input buttons, transmitters, processors, memory, batteries, charging circuits, and system-on-chip (SoC) architectures can be mounted on or connected to a circuit board; or electrically connected to trace layers and / or ground layers in the circuit board. For example, an RF source is disposed on a trace layer.

[0140] Any of the aforementioned grounding layers, ground planes, or grounding metal layers are made of conductive materials. In one embodiment, the conductive material may be any of the following: copper, aluminum, stainless steel, brass and their alloys, copper foil on an insulating substrate, aluminum foil on an insulating substrate, gold foil on an insulating substrate, silver-plated copper, silver-plated copper foil on an insulating substrate, silver foil on an insulating substrate and tin-plated copper, graphite-impregnated cloth, graphite-coated substrates, copper-plated substrates, brass-plated substrates, and aluminum-plated substrates. Those skilled in the art will understand that grounding layers / ground planes / grounding metal layers may also be made of other conductive materials.

[0141] Grounding: refers to coupling with the aforementioned ground / floor in any way. In one embodiment, grounding can be achieved through physical grounding, such as through a structural component of the mid-frame to achieve a physical ground at a specific location on the frame (or, physical ground). In another embodiment, grounding can be achieved through device grounding, such as through devices like capacitors / inductors / resistors connected in series or parallel (or, device ground).

[0142] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings.

[0143] like Figure 1 As shown, the electronic device 10 may include: a cover 13, a display / module 15, a printed circuit board (PCB) 17, a middle frame 19, and a rear cover 21. It should be understood that in some embodiments, the cover 13 may be a glass cover, but it may also be replaced with a cover made of other materials, such as a PET (Polyethylene terephthalate) cover.

[0144] The cover plate 13 can be set close to the display module 15, and can be mainly used to protect the display module 15 from dust.

[0145] In one embodiment, the display module 15 may include a liquid crystal display (LCD), a light emitting diode (LED) display panel, or an organic light-emitting diode (OLED) display panel, etc., and this application embodiment does not limit this.

[0146] The middle frame 19 mainly serves to support the entire machine. Figure 1The diagram shows PCB 17 positioned between the middle frame 19 and the back cover 21. It should be understood that in one embodiment, PCB 17 may also be positioned between the middle frame 19 and the display module 15; this application does not limit this. The printed circuit board PCB 17 can be made of flame-retardant material (FR-4) dielectric substrate, Rogers dielectric substrate, or a hybrid dielectric substrate of Rogers and FR-4, etc. Here, FR-4 is a designation for a flame-retardant material grade, and Rogers dielectric substrate is a high-frequency board. Electronic components, such as radio frequency chips, are carried on PCB 17. In one embodiment, a metal layer can be provided on the printed circuit board PCB 17. This metal layer can be used for grounding the electronic components carried on the printed circuit board PCB 17, or for grounding other components, such as bracket antennas, frame antennas, etc. This metal layer can be called a ground plane, grounding plate, or grounding layer. In one embodiment, this metal layer can be formed by etching metal onto the surface of any dielectric substrate in PCB 17. In one embodiment, the grounding metal layer can be located on the side of the printed circuit board PCB 17 near the middle frame 19. In one embodiment, the edge of the printed circuit board PCB 17 can be considered as the edge of its ground plane. In one embodiment, the metal frame 19 can also be used for grounding the aforementioned components. The electronic device 10 may also have other ground planes / grounding layers, as previously described, and will not be repeated here.

[0147] The electronic device 10 may also include a battery (not shown in the figure). The battery may be disposed between the middle frame 19 and the back cover 21, or between the middle frame 19 and the display module 15; this embodiment does not limit this. In some embodiments, the PCB 17 is divided into a motherboard and a daughterboard, and the battery may be disposed between the motherboard and the daughterboard. The motherboard may be disposed between the middle frame 19 and the upper edge of the battery, and the daughterboard may be disposed between the middle frame 19 and the lower edge of the battery.

[0148] The electronic device 10 may also include a bezel 11, which may be formed of a conductive material such as metal. The bezel 11 may be disposed between the display module 15 and the back cover 21 and extend circumferentially around the periphery of the electronic device 10. The bezel 11 may have four sides surrounding the display module 15 to help secure the display module 15.

[0149] In one implementation, the frame 11 made of conductive material can be directly used as the conductive frame of the electronic device 10, for example, forming the appearance of a metal frame, suitable for industrial design (ID). In another implementation, the outer surface of the frame 11 can be a conductive material, such as a metal material, thereby forming the appearance of a metal frame. In these implementations, the conductive portion of the frame 11 can be used as an antenna radiator of the electronic device 10.

[0150] In another implementation, the outer surface of the frame 11 can also be a non-conductive material, such as plastic, forming a non-metallic frame appearance suitable for non-metallic IDs. In one implementation, the inner surface of the frame 11 can include a conductive material, such as a metallic material. In this implementation, the conductive portion of the frame 11 can be used as an antenna radiator of the electronic device 10. It should be understood that the radiator (or, in other words, the conductive material of the inner surface) disposed on the inner surface of the frame 11 is attached to the non-conductive material of the frame 11 to facilitate antenna radiation, and both the conductive and non-conductive materials should be considered as part of the frame 11.

[0151] The middle frame 19 may include the frame 11. The middle frame 19, including the frame 11, is a single unit that supports the electronic components in the device. The cover plate 13 and the rear cover 21 respectively cover the upper and lower edges of the frame to form the housing of the electronic device. In one embodiment, the cover plate 13, the rear cover 21, the frame 11, and / or the middle frame 19 may be collectively referred to as the housing of the electronic device 10. It should be understood that "housing" may refer to part or all of any one of the cover plate 13, the rear cover 21, the frame 11, or the middle frame 19, or to any combination of the cover plate 13, the rear cover 21, the frame 11, or the middle frame 19.

[0152] The border 11 on the middle frame 19 can at least partially serve as an antenna radiator to receive / transmit radio frequency signals. This portion of the border serving as the radiator can have gaps between it and the rest of the middle frame 19, thereby ensuring a good radiation environment for the antenna radiator. In one embodiment, the middle frame 19 can have an aperture at this portion of the border serving as the radiator to facilitate antenna radiation.

[0153] Alternatively, the frame 11 may not be considered part of the middle frame 19. In one embodiment, the frame 11 may be connected to and integrally formed with the middle frame 19. In another embodiment, the frame 11 may include inwardly extending protrusions to connect with the middle frame 19, for example, by means of spring clips, screws, welding, etc. The protrusions of the frame 11 can also be used to receive feed signals, so that at least a portion of the frame 11 acts as a radiator of the antenna to transmit / receive radio frequency signals. A gap 42 may exist between this portion of the frame acting as the radiator and the middle frame 30, thereby ensuring that the antenna radiator has a good radiation environment, enabling the antenna to have good signal transmission capabilities.

[0154] The back cover 21 can be made of metal; it can also be made of non-conductive material, such as a glass back cover, a plastic back cover, or other non-metallic back cover; or it can be made of both conductive and non-conductive materials. In one embodiment, the back cover 21, which includes conductive material, can replace the middle frame 19 and form an integral part with the frame 11, providing support for the electronic components in the whole device.

[0155] In one embodiment, conductive portions in the mid-frame 19 and / or rear cover 21 can serve as a reference ground for the electronic device 10, wherein the frame 11, PCB 17, etc. of the electronic device can be grounded through electrical connection with the mid-frame.

[0156] The antenna of the electronic device 10 can also be disposed within the frame 11. When the frame 11 of the electronic device 10 is made of a non-conductive material, the antenna radiator can be located within the electronic device 10 and positioned along the frame 11. For example, the antenna radiator can be positioned close to the frame 11 to minimize the volume occupied by the antenna radiator and to be closer to the outside of the electronic device 10, thereby achieving better signal transmission performance. It should be noted that "positioning the antenna radiator close to the frame 11" means that the antenna radiator can be positioned flush against the frame 11 or close to the frame 11, for example, there can be a small gap between the antenna radiator and the frame 11.

[0157] The antenna of electronic device 10 can also be housed inside the casing, such as a bracket antenna, millimeter-wave antenna, etc. Figure 1 (Not shown in the image). The clearance of the antenna disposed within the housing can be obtained by a slot / aperture on any of the middle frame, and / or bezel, and / or back cover, and / or display screen, or by a non-conductive gap / aperture formed between any of them. The clearance setting of the antenna can ensure the radiation characteristics of the antenna. It should be understood that the clearance of the antenna can be a non-conductive area formed by any conductive components within the electronic device 10, through which the antenna radiates signals to the external space. In one embodiment, the antenna 40 can be in the form of an antenna based on a flexible printed circuit (FPC), an antenna based on laser-direct-structuring (LDS), or a microstrip disk antenna (MDA), etc. In one embodiment, the antenna can also be a transparent structure embedded inside the screen of the electronic device 10, making the antenna a transparent antenna embedded inside the screen of the electronic device 10.

[0158] Figure 1 The electronic device 10 is shown only schematically, and the actual shape, size, and construction of these components are not subject to change. Figure 1 limited.

[0159] It should be understood that in the embodiments of this application, the side where the display screen of the electronic device is located can be considered as the front, the side where the back cover is located as the back, and the side where the frame is located as the side.

[0160] It should be understood that, in the embodiments of this application, when a user holds (typically vertically and facing the screen) an electronic device, the orientation of the electronic device includes a top, bottom, left side, and right side.

[0161] This application provides an electronic device including an antenna. The antenna has a conductive portion of the frame of the electronic device as the main radiator and / or parasitic branches, which can improve the user's experience when performing satellite navigation or communication.

[0162] First, by Figure 2 and Figure 3 This application will involve two antenna modes. Among them, Figure 2 This is a schematic diagram of the common-mode structure of an antenna provided in this application and the corresponding current and electric field distribution. Figure 3 This is a schematic diagram of the differential mode structure of another antenna provided in this application and the corresponding current and electric field distribution. Figure 2 and Figure 3 The antenna radiator is open at both ends, and its common-mode and differential-mode modes can be referred to as line common-mode and line differential-mode, respectively.

[0163] It should be understood that the “common-differential mode” or “CM-DM mode” in this application refers to the linear common-mode mode and the linear differential-mode mode generated on the same radiator.

[0164] 1. Wire common mode (CM) mode

[0165] Figure 2 Figure (a) shows that the radiator of antenna 40 is open at both ends and connected to a feed circuit (not shown) at the middle position 41. In one embodiment, the antenna 40 is fed in a symmetrical feed configuration. The feed circuit can be connected to the middle position 41 of antenna 40 via feed wire 42. It should be understood that symmetrical feed can be understood as one end of the feed circuit being connected to the radiator and the other end being coupled to the ground to achieve grounding, wherein the connection point between the feed circuit and the radiator (feed point) is located at the center of the radiator, which may be, for example, the midpoint of the geometry, or the midpoint of the electrical length (or a certain area within a certain range near the aforementioned midpoint).

[0166] The middle position 41 of the antenna 40 may be, for example, the geometric center of the antenna, or the midpoint of the electrical length of the radiator, such as the connection point between the feed line 42 and the antenna 40, which covers the middle position 41.

[0167] Figure 2 Figure (b) shows the current and electric field distribution of antenna 40. Figure 2 As shown in (b), the current exhibits an opposite distribution on both sides of the middle position 41, for example, a symmetrical distribution; the electric field exhibits a unidirectional distribution on both sides of the middle position 41. Figure 2 As shown in (b), the current at feeder line 42 exhibits a unidirectional distribution. Based on the unidirectional current distribution at feeder line 42, Figure 2 The type of feed shown in (a) can be called a line CM feed. This is based on the fact that the current is distributed in opposite directions on both sides of the connection between the radiator and the feed line 42. Figure 2 The antenna mode shown in (b) can be called the line CM mode (or simply CM mode; for example, for a line antenna, CM mode refers to the line CM mode). Figure 2 The current and electric field shown in (b) can be referred to as the current and electric field of the line CM mode, respectively.

[0168] The current is stronger at the middle position 41 of antenna 40 (the current is strongest near the middle position 41 of antenna 40), and weaker at both ends of antenna 40. Figure 2 As shown in (b) of the diagram. The electric field is weaker at the middle position 41 of the antenna 40 and stronger at both ends of the antenna 40.

[0169] 2. Differential mode (DM)

[0170] like Figure 3 Image (a) shows that the two radiators of antenna 50 have open ends on both sides and are connected to a feed circuit at the middle position 51. In one embodiment, antenna 50 is fed using an anti-symmetrical feed. One end of the feed circuit is connected to one of the radiators via a feed wire 52, and the other end of the feed circuit is connected to the other radiator via a feed wire 52. The middle position 51 can be the geometric center of antenna 50, or the gap formed between the radiators.

[0171] It should be understood that the "center-antisymmetric feeding" mentioned in this application can be understood as the positive and negative poles of the feeding unit being connected to two connection points near the midpoint of the radiator. In one embodiment, the signal amplitudes output by the positive and negative poles of the feeding unit are the same, but the phases are opposite, for example, the phase difference is 180°±10°.

[0172] Figure 3(b) shows the current and electric field distribution of antenna 50. Figure 3 As shown in (b), the current in the antenna 50 is distributed in the same direction on both sides of the middle position 51, for example, an antisymmetric distribution; the electric field is distributed in opposite directions on both sides of the middle position 51. Figure 3 As shown in (b), the current at feeder line 52 exhibits a reverse distribution. Based on the reverse current distribution at feeder line 52, Figure 3 The type of feed shown in (a) can be called a line DM feed. This is based on the fact that the current is distributed in the same direction on both sides of the connection between the radiator and the feed line 52. Figure 3 The antenna mode shown in (b) can be called the line DM mode (or simply DM mode; for example, for a line antenna, DM mode refers to the line DM mode). Figure 3 The current and electric field shown in (b) can be referred to as the current and electric field in the line DM mode, respectively. It should be understood that this is based on the fact that the current is distributed in the same direction on both sides of the connection between the radiator and the feed line 52. Figure 3 The antenna mode shown in (b) can also be called the half-antenna mode, or the half-wavelength mode, or simply the half-mode.

[0173] In one embodiment, in online DM mode, or half-mode, the current is stronger at the middle position 51 of antenna 50 (the current peak is located near the middle position 51 of antenna 50), and weaker at both ends of antenna 50, such as... Figure 3 As shown in (b) of the diagram. The electric field is weaker at the middle position 51 of the antenna 50 and stronger at both ends of the linear antenna 50.

[0174] It should be understood that an antenna radiator can be considered as a metal structural component that generates radiation, and its quantity can be one, such as... Figure 2 As shown, or, it can be two items, such as Figure 3 As shown, adjustments can be made according to actual design or production needs. For example, for the line CM mode, it can also be as follows: Figure 3 The diagram illustrates the use of two radiators, positioned opposite each other with a gap between them. Symmetrical feeding is employed at the two ends closest to each other; for example, feeding the same feed source signal into both ends of the two radiators can achieve the same result as... Figure 2 The antenna structure shown achieves a similar effect. Correspondingly, for line DM mode, it can also be done as follows... Figure 2 The diagram illustrates a radiator with two feed points positioned at its center, using an anti-symmetrical feeding method. For example, by feeding signals of the same amplitude but opposite phase to the two symmetrical feed points on the radiator, a signal similar to [the one described above] can be obtained. Figure 3 The antenna structure shown has a similar effect.

[0175] 3. Line CM-DM mode

[0176] The above Figure 2 and Figure 3 The diagrams show how different feeding methods generate line CM mode and line DM mode when both ends of the radiator are open.

[0177] When the antenna uses asymmetrical feeding (the feed point is off-center from the radiator, including side-feed or offset feeding), or when the grounding point of the radiator (coupled to the ground) is asymmetrical (off-center from the radiator), the antenna can simultaneously generate a first resonance and a second resonance, corresponding to the line CM mode and the line DM mode, respectively. For example, the first resonance corresponds to the line CM mode, with current and electric field distributions as follows: Figure 2 As shown in (b) above. The second resonance corresponds to the line DM mode, and the current and electric field distribution is as follows. Figure 3 As shown in (b) of the diagram.

[0178] Figure 4 This is a schematic diagram of another electronic device 10 provided in the embodiments of this application.

[0179] like Figure 4 As shown, the conductive frame 11 of the electronic device 10 may include a first side 131 and a second side 132 that intersect at an angle, and the length of the first side 131 is greater than the length of the second side 132.

[0180] The second side 132 may have a first position 101 and a second position 102, and the frame 11 has a gap between the first position 101 and the second position 102. The radiator 105 of the antenna 100 may include a conductive portion of the frame between the first position 101 and the second position 102.

[0181] In one embodiment, the first border 105 is symmetrical along the virtual axis of the second side 132, and the lengths of the second side 132 on both sides of the virtual axis are the same. Due to certain errors in engineering applications, when the ratio between the distances of the first position 101 and the second position 102 and the virtual axis is greater than or equal to 90% and less than or equal to 110%, the first border 105 can be considered symmetrical along the virtual axis of the second side 132.

[0182] It should be understood that for an antenna, as the antenna structure becomes more symmetrical (e.g., the radiator 105 is located at the center of the second side 132), the antenna's radiation characteristics are improved (e.g., bandwidth, radiation efficiency, etc.).

[0183] Figure 5 and Figure 6 yes Figure 4 The simulation results of antenna 100 in the electronic device 10 are shown. Among them, Figure 5 yes Figure 4 Simulation results of the S-parameters of the antenna 100 in the electronic device 10 shown. Figure 6 yes Figure 4 Simulation results of the system efficiency and radiation efficiency of antenna 100 in the electronic device 10 shown.

[0184] like Figure 5 As shown, when Figure 4 The antennas shown are respectively using Figure 2 and Figure 3 The feeding method shown can generate line CM mode and line DM mode respectively. In both line CM mode and line DM mode, the antenna can resonate near the target frequency band (e.g., 2 GHz).

[0185] It should be understood that, for the sake of brevity, this embodiment only uses the excitation of the line CM mode and the line DM mode as examples. Referring to the above embodiment, the line CM mode and the line DM mode can also be excited simultaneously by asymmetrical feeding (the feeding point is deviated from the middle position of the radiator, including side feeding or offset feeding) and / or the grounding point of the radiator (coupled with the ground) is asymmetrical (the grounding point is deviated from the middle position of the radiator).

[0186] like Figure 6 As shown, when the first frame (radiator) is symmetrical along the virtual axis of the second side (located at the center of the second side), at the resonant point (2GHz), the radiation efficiency of CM mode is -4.42dB and the system efficiency is -4.47dB, while the radiation efficiency of DM mode is -1.27dB and the system efficiency is -1.39dB.

[0187] It should be understood that when the first frame is located at the center of the second frame, it can excite the lateral mode (which accounts for more than the vertical mode), but the currents corresponding to the lateral modes will cancel each other out. Therefore, the system efficiency and radiation efficiency of the CM mode are low.

[0188] In DM mode, the antenna radiation is mainly generated by the radiator (first frame). When placed at the center of the second frame, the system efficiency and radiation efficiency are better than those in CM mode.

[0189] Figure 7 This is a schematic diagram of an electronic device 10 provided in an embodiment of this application.

[0190] like Figure 7 As shown, the electronic device 10 includes a frame 11, an antenna 200, and a floor 300.

[0191] The border 11 may include a first side 131 and a second side 132 that intersect at an angle, wherein the length of the first side 131 is greater than the length of the second side 132.

[0192] It should be understood that the technical solutions provided in the embodiments of this application can also be applied to foldable electronic devices. For the sake of brevity, only an electronic device including a single display screen (non-foldable) is used as an example for explanation. In a foldable electronic device, the first side 131 and the second side 132 mentioned above can be understood as the first side and the second side corresponding to the foldable electronic device when it is in a folded state.

[0193] The second side 132 may have a first position 201 and a second position 202, and a first grounding element located between the first position 201 and the second position 202. The frame 11 has a first gap and a second gap respectively at the first position 201 and the second position 202. The frame 11 is coupled to the floor 300 through the first grounding element.

[0194] In one embodiment, the width of the gaps opened at the first position 201 and the second position 202 is greater than or equal to 0.2 mm and less than or equal to 1.5 mm. All gaps opened in this embodiment are within the above range. It should be understood that the width of the gap can be understood as the distance between the ends of the edges of the two sides of the gap.

[0195] The antenna 200 includes a first radiator 211, a first feed circuit 221, a first tuning circuit 251, and a second tuning circuit 252.

[0196] The first radiator 211 is the conductive portion of the frame of the first position 201 and the second position 202. The first end (the end near the first position 201) and the second end (the end near the second position 202) of the first radiator 211 are open ends.

[0197] The first radiator 211 includes a first feed point 231. The distance between the first feed point 231 and the first position 201 is different from the distance between the first feed point 231 and the second position 202, so that the first radiator 211 can simultaneously generate line CM mode and line DM mode. The first feed circuit 221 is coupled to the first feed point 231 and is used to feed an electrical signal to excite the antenna 200 to resonate. The difference between the distance between the first feed point 231 and the first position 201 and the distance between the first feed point 231 and the second position 202 can also be understood as the difference between the length of the first radiator 211 between the first feed point 231 and the first end and the length between the first feed point and the second end. It should be understood that the "distance" from the first point / first end / first position on the radiator / frame to the second point / second end / second position can be interpreted in the same or similar way in this application.

[0198] It should be understood that the difference in distance between the first feed point 231 and the first position 201 and the second position 202 can be interpreted as the absolute value of the difference between the first distance between the first feed circuit 221 and the first position 201 and the second distance between the first feed point 231 and the second position 202 being greater than or equal to 5mm. Furthermore, for the sake of brevity, this application embodiment only uses the electrical connection between the first feed circuit 221 and the first feed point 231 as an example for illustration. In practical applications, indirect coupling connection can also be used, and this application embodiment does not impose any limitations on this. Moreover, in this application embodiment, all coupling connections can be understood accordingly.

[0199] The first radiator 211 also includes a first connection point 2111 and a second connection point 2112. The first connection point 2111 is located between the first position 201 and the first grounding element. The second connection point 2112 is located between the second position 202 and the first grounding element. The first tuning circuit 251 is coupled to the first connection point 2111, and the second tuning circuit 252 is coupled to the second connection point 2112.

[0200] It should be understood that the first tuning circuit 251 and the second tuning circuit 252 can be used to adjust the resonant frequency of the resonance generated by the first radiator 211, so that the antenna 200 can operate in different operating frequency bands.

[0201] In one embodiment, the first tuning circuit 251 and the second tuning circuit 252 are in a first circuit state, and the first radiator 211 is used to generate a first main resonance, the resonant frequency band of which includes a first frequency band. In another embodiment, the first tuning circuit 251 and the second tuning circuit 252 are in a first circuit state, and the first radiator 211 is used to generate a first resonance and a second resonance, the resonant frequency of the first resonance being lower than the resonant frequency of the second resonance, and the second resonance being the first main resonance.

[0202] In one embodiment, the first tuning circuit 251 and the second tuning circuit 252 are in a second circuit state, and the first radiator 211 is used to generate a second main resonance, the resonant frequency band of which includes the second frequency band. In another embodiment, the first tuning circuit 251 and the second tuning circuit 252 are in a second circuit state, and the first radiator 211 is used to generate a third resonance and a fourth resonance, the resonant frequency of the third resonance being lower than the resonant frequency of the fourth resonance, and the fourth resonance being the second main resonance.

[0203] It should be understood that, according to the technical solution provided in the embodiments of this application, the first radiator 211 can be simultaneously excited in both the linear CM mode and the linear DM mode by means of bias feeding (the distance between the first feed point 231 and the first position 201 and the second position 202 is different). In the first circuit state, the first resonance is mainly generated by the linear CM mode, and the second resonance is mainly generated by the linear DM mode. In the second circuit state, the third resonance is mainly generated by the linear CM mode, and the fourth resonance is mainly generated by the linear DM mode.

[0204] As can be seen from the above embodiments, when the first radiator 211 is disposed on the second side 132, the antenna 200 exhibits high radiation efficiency and system efficiency in the resonant mode generated by the linear DM mode. Since the antenna gain is related to its directivity and efficiency (radiation efficiency and system efficiency), increasing the antenna efficiency (radiation efficiency and system efficiency) without changing the directivity can also improve the antenna gain. Therefore, although the polarization characteristic of the radiation generated by the antenna 200 is linear polarization when the electronic device 10 communicates in the first or second frequency band, resulting in a 3dB loss when receiving circularly polarized electromagnetic waves, the antenna 200 possesses good efficiency (radiation efficiency and system efficiency), and correspondingly, also exhibits good directivity.

[0205] In one embodiment, the first grounding element may be located in the central region of the first radiator 211. The central region includes the center of the first radiator 211, and the lengths of the first radiators 211 on both sides of the center are the same. The central region of the first radiator 211 can be understood as the area within 5 mm of the center of the first radiator 211. The first grounding element being located in the central region of the first radiator 211 can be understood as the center of the first grounding element being located within the aforementioned central region of the first radiator 211.

[0206] It should be understood that when the first radiator 211 generates the first or second main resonance, it corresponds to the line DM mode. In the line DM mode, the central region includes the current-high point, and placing the first grounding element in the region near the current-high point will not affect the first or second main resonance.

[0207] In one embodiment, the first tuning circuit 251 and the second tuning circuit 252 are circuits including switches. The switches can be used to switch electronic components coupled to the connection point with different resistance, capacitance, or inductance values ​​when different circuit states are being used. Alternatively, the switches can be in an open state, preventing the electronic components from being coupled to the connection point. Alternatively, the switches can allow the ground plane 300 to be directly coupled to the connection point, without any electronic components between the ground plane 300 and the connection point.

[0208] In one embodiment, the first tuning circuit 251 and the second tuning circuit 252 do not include switches and can be circuits formed by cascading multiple electronic components. The first tuning circuit 251 and the second tuning circuit 252 can have different equivalent capacitance or equivalent inductance values ​​at different frequencies.

[0209] In one embodiment, the first frequency band and the second frequency band can correspond to the transmitting and receiving frequency bands in satellite communication, respectively. For example, in the Tiantong satellite system, the first frequency band may include 1980MHz-2010MHz, and the second frequency band may include 2170MHz-2200MHz. In the BeiDou satellite system, the first frequency band may include 1610MHz-1626.5MHz, and the second frequency band may include 2483.5MHz-2500MHz. Alternatively, it can be applied to other satellite communication systems, and this application embodiment does not limit this.

[0210] In one embodiment, when antenna 200 operates in the Tiantong satellite system (the operating frequency band of antenna 200 includes at least a portion of the frequency bands in the Tiantong satellite system), electronic device 10 can perform voice communication via antenna 200. In one embodiment, when antenna 200 operates in the Beidou satellite system (the operating frequency band of antenna 200 includes at least a portion of the frequency bands in the Beidou satellite system), electronic device 10 can send or receive short messages via antenna 200.

[0211] It should be understood that, for the sake of brevity, the satellite communication of the electronic device 10 described in the embodiments of this application can be understood as the electronic device 10 using the antenna 200 to send or receive short messages to or from the satellite, or the electronic device 10 using the antenna 200 to conduct voice communication via the satellite.

[0212] In one embodiment, the frequency difference between the resonant point of the second resonance and the resonant point of the first resonance is less than or equal to 300 MHz. In another embodiment, the frequency difference between the resonant point of the second resonance and the resonant point of the first resonance is greater than or equal to 100 MHz.

[0213] In one embodiment, the frequency difference between the resonant point of the fourth resonance and the resonant point of the third resonance is less than or equal to 300 MHz. In another embodiment, the frequency difference between the resonant point of the fourth resonance and the resonant point of the third resonance is greater than or equal to 100 MHz.

[0214] It should be understood that the first radiator 211 resonates using both linear CM and linear DM modes. When the frequency difference between the resonant point of the second resonance (fourth resonance) and the resonant point of the first resonance (third resonance) is greater than or equal to 100MHz and less than or equal to 300MHz, the proportion of the linear DM mode in the second resonance (fourth resonance) can be increased. This allows the antenna 200 to radiate primarily using the linear DM mode in the resonant frequency band of the second resonance (fourth resonance), thereby improving the radiation efficiency and system efficiency of the antenna 200 in the first frequency band (second frequency band). When the frequency difference between the resonant point of the second resonance (fourth resonance) and the resonant point of the first resonance (third resonance) is greater than 300MHz, the proportion of other operating modes (e.g., linear CM mode) in the second resonance (fourth resonance) increases, leading to a decrease in the radiation efficiency and system efficiency of the antenna 200 in the first frequency band (second frequency band).

[0215] In one embodiment, the frequency difference between the resonant point of the second resonance and the resonant point of the first resonance, and / or the frequency difference between the resonant point of the fourth resonance and the resonant point of the third resonance, can be determined based on the width of the connection between the first grounding member and the frame 11 and the center frequency of the operating frequency band of the antenna 200.

[0216] In one embodiment, the center frequency of the operating frequency band of the antenna 200 is greater than or equal to 1 GHz and less than 2.5 GHz. For example, the operating frequency band includes at least some frequency bands in the Tiantong satellite system and at least some frequency bands in the Beidou satellite system.

[0217] When the width of the connection between the first grounding element and the frame 11 is greater than or equal to 2mm and less than 4mm, the frequency difference between the resonant point of the second resonance and the resonant point of the first resonance is less than or equal to 450MHz, and / or the frequency difference between the resonant point of the fourth resonance and the resonant point of the third resonance is less than or equal to 450MHz. The frequency difference between the resonant point of the second resonance and the resonant point of the first resonance is greater than or equal to 50MHz, and / or the frequency difference between the resonant point of the fourth resonance and the resonant point of the third resonance is greater than or equal to 50MHz.

[0218] When the width of the connection between the first grounding element and the frame 11 is greater than or equal to 4 mm and less than or equal to 8 mm, the frequency difference between the resonant point of the second resonance and the resonant point of the first resonance is less than or equal to 400 MHz, and / or the frequency difference between the resonant point of the fourth resonance and the resonant point of the third resonance is less than or equal to 400 MHz. The frequency difference between the resonant point of the second resonance and the resonant point of the first resonance is greater than or equal to 50 MHz, and / or the frequency difference between the resonant point of the fourth resonance and the resonant point of the third resonance is greater than or equal to 50 MHz.

[0219] In one embodiment, the center frequency of the operating frequency band of the antenna 200 is greater than or equal to 2.5 GHz and less than or equal to 5 GHz. For example, the operating frequency band includes at least a portion of the frequency bands in other systems.

[0220] When the width of the connection between the first grounding element and the frame 11 is greater than or equal to 2mm and less than 4mm, the frequency difference between the resonant point of the second resonance and the resonant point of the first resonance is less than or equal to 450MHz, and / or the frequency difference between the resonant point of the fourth resonance and the resonant point of the third resonance is less than or equal to 450MHz. The frequency difference between the resonant point of the second resonance and the resonant point of the first resonance is greater than or equal to 100MHz, and / or the frequency difference between the resonant point of the fourth resonance and the resonant point of the third resonance is greater than or equal to 100MHz.

[0221] When the width of the connection between the first grounding element and the frame 11 is greater than or equal to 4mm and less than or equal to 8mm, the frequency difference between the resonant point of the second resonance and the resonant point of the first resonance is less than or equal to 400MHz, and / or the frequency difference between the resonant point of the fourth resonance and the resonant point of the third resonance is less than or equal to 400MHz. The frequency difference between the resonant point of the second resonance and the resonant point of the first resonance is greater than or equal to 100MHz, and / or the frequency difference between the resonant point of the fourth resonance and the resonant point of the third resonance is greater than or equal to 100MHz.

[0222] In one embodiment, the first feeding circuit may include a first radio frequency (RF) channel and a second RF channel. The first RF channel (for feeding in an electrical signal of a first frequency band) generates a first resonance and a second resonance, and the second RF channel (for feeding in an electrical signal of a second frequency band) generates a third resonance and a fourth resonance. The first RF channel can be used to feed in the first electrical signal and may correspond to the transmit frequency band in satellite communication. The second RF channel can be used to feed in the second electrical signal and may correspond to the receive frequency band in satellite communication. The first RF channel and the second RF channel can be understood as two different circuits for transmitting electrical signals; for example, they can be understood as two different RF channels in a radio frequency integrated circuit (RFIC).

[0223] It should be understood that the power supply circuits provided in the embodiments of this application can all have the above-described structure. By feeding electrical signals in a combined manner, the number of power supply points on the radiator can be reduced, thereby reducing the complexity of the system design.

[0224] In one embodiment, the length of the first radiator 211 between the first connection point 2111 and the first end is less than or equal to half the length of the first radiator 211 between the first grounding member and the first end.

[0225] In one embodiment, the distance between the first connection point 2111 and the first position 201 on the first radiator 211 is less than or equal to half the distance between the first grounding member and the first position 201 on the first radiator 211.

[0226] In one embodiment, the grounding element has a certain width and is connected to the radiator along the width direction. In one embodiment, the length of the radiator between the grounding element and the first end, or the distance between the grounding element and the first position on the radiator, can be understood as the shortest distance / length from the first end of the radiator to the grounding element, that is, the distance / length to the nearest edge of the grounding element.

[0227] In one embodiment, the location where the radiator connects to the grounding element can be considered as a grounding point on the radiator. For the sake of brevity, the embodiment will be described below with the location (e.g., an edge location) where the grounding element connects to the radiator as the first grounding point 241. It should be understood that the calculation of the distance / length associated with the grounding element should be understood with reference to the foregoing.

[0228] In one embodiment, the length D1 of the border between the first connection point 2111 and the first position 201 and the length L1 of the border between the distance between the first position 201 and the second position 202 satisfy: D1 ≤ L1 × 30%. In another embodiment, D1 ≤ L1 × 10%, such as... Figure 8 As shown. In one embodiment, D1 is less than or equal to 8 mm.

[0229] It should be understood that, in the embodiments of this application, the length of the frame (or radiator) between A and B can be understood as the length of the conductor portion between A and B. For example, when coupled to A or B through a metal component such as a metal spring, it can be understood as the distance between the center of the end of the metal component connected to A or B.

[0230] In one embodiment, the length of the first radiator 211 between the second connection point 2112 and the second end is less than or equal to half the length of the first radiator 211 between the first grounding point 241 and the second end. In another embodiment, the distance between the second connection point 2112 and the second position 202 on the first radiator 211 is less than or equal to half the distance between the first grounding point 241 and the second position 202 on the first radiator 211.

[0231] In one embodiment, the length D2 of the border between the second connection point 2112 and the second position 202 and the length L1 of the border between the distance between the first position 201 and the second position 202 satisfy: D2 ≤ L1 × 30%. In another embodiment, D2 ≤ L1 × 10%, such as... Figure 8 As shown. In one embodiment, D2 is less than or equal to 8 mm.

[0232] It should be understood that the first connection point 2111 and the second connection point 2112 can be located in the region near the first gap and the second gap. The first end and the second end of the first radiator 211 are open ends. In the region near the open ends, there is generally a strong electric field. The region with a strong electric field has better tuning performance.

[0233] In one embodiment, the first position 201 and the second position 202 are symmetrical along a virtual axis of the second side 132, and the lengths of the second sides on both sides of the virtual axis are the same. Due to certain errors in engineering applications, when the ratio of the virtual axis to the distance between the first position 201 and the second position 202 is greater than or equal to 90% and less than or equal to 110%, the first position 201 and the second position 202 can be considered symmetrical along the virtual axis of the second side 132.

[0234] It should be understood that as the symmetry of the first radiator 211 increases, the radiation characteristics of the antenna 200 are improved (e.g., bandwidth, radiation efficiency, etc.).

[0235] In one embodiment, the first power supply point 231 may coincide with either the first connection point 2111 or the second connection point 2112.

[0236] It should be understood that, in the embodiments of this application, the power supply circuit can be coupled to the power supply point through a power supply component (e.g., a metal spring). When the power supply point coincides with the connection point, both the tuning circuit and the power supply circuit can be coupled to the radiator (power supply point / connection point) through the power supply component, so as to reduce the number of connection positions on the radiator and facilitate engineering implementation.

[0237] Figure 9A This is a schematic diagram of an electronic device 10 provided in an embodiment of this application.

[0238] like Figure 9A As shown, the electronic device 10 may include a conductive frame 11, an antenna 200, and a first feed circuit 221.

[0239] The frame 11 includes a first position 201, a second position 202, and a third position 203. The second position 202 is located between the first position 204 and the third position 203. A first grounding point 241 is also included between the second position 202 and the third position 203.

[0240] Antenna 210 includes a first radiator 211, a second radiator 212, and a third radiator 213. The first radiator 211 includes at least a portion of a frame between a first position 201 and a second position 202, the second radiator 212 includes at least a portion of a frame between the second position 202 and a first ground point 241, and the third radiator 213 includes at least a portion of a frame between the first ground point 241 and a third position 203.

[0241] It should be understood that in some actual production or design, the radiator may also include metal parts disposed around the frame. For the sake of brevity, this application embodiment only uses the part of the frame as the radiator as an example for illustration, and does not limit this.

[0242] The frame 11 has slits at the first position 201, the second position 202, and the third position 203. In one embodiment, the width of the slits at the first position 201, the second position 202, and the third position 203 is greater than or equal to 0.2 mm and less than or equal to 1.5 mm. In this embodiment, the slits formed by the slits are all within the above range. It should be understood that the width of the slit can be understood as the distance between the ends of the frame on both sides of the slit.

[0243] The frame 11 is grounded at the first grounding point 241. The first end (near the first position 201) and the second end (near the second position 202) of the first radiator 211 are open terminals. The first end (near the second position 202) of the second radiator 212 is an open terminal, and the second end is a grounded terminal (near the first grounding point 241). The first end (near the first grounding point 241) of the third radiator 213 is a grounded terminal, and the second end is an open terminal (near the third position 203).

[0244] The first radiator 211 includes a first feed point 231. The distance between the first feed point 231 and the first position 201 is different from the distance between the first feed point 231 and the second position 202. The first feed circuit 221 is coupled to the first feed point 231 and is used to feed in an electrical signal to excite the antenna 200 to resonate.

[0245] It should be understood that the difference in distance between the first feed point 231 and the first position 201 and the second position 202 can be interpreted as the absolute value of the difference between the first distance between the first feed point 231 and the first position 201 and the second distance between the first feed point 231 and the second position 202 being greater than or equal to 5mm. Furthermore, for the sake of brevity, this application embodiment only uses the electrical connection between the first feed circuit 221 and the first feed point 231 as an example for illustration. In practical applications, indirect coupling connection can also be used, and this application embodiment does not impose any limitations on this. Moreover, in this application embodiment, all coupling connections can be understood accordingly.

[0246] In one embodiment, the border 11 includes a first side 131 and a second side 132 that intersect at an angle, the length of the first side 131 is greater than the length of the second side 132, and the first position 201 and the second position 202 are located on the second side 132.

[0247] The first radiator 211 is used to generate a first resonance and a second resonance. The resonant frequency of the first resonance is lower than that of the second resonance, and the resonant frequency band of the second resonance includes the first frequency band.

[0248] The third radiator 213 is used to generate a first parasitic resonance, the resonant frequency of which is lower than that of the second resonance.

[0249] It should be understood that, according to the technical solution provided in the embodiments of this application, by using side feeding (the distance between the first feed point 231 and the first position 201 and the second position 202 is different), the CM mode and DM mode of the first radiator 211 can be excited simultaneously, generating the first resonance (mainly generated by the CM mode) and the second resonance (mainly generated by the DM mode), respectively. As can be seen from the above embodiments, when the first radiator 211 is disposed on the second side 132, the radiation efficiency and system efficiency of the resonance generated by the DM mode of the antenna 200 are relatively high. Since the directivity of the antenna is related to the antenna gain and efficiency (radiation efficiency and system efficiency), improving the antenna efficiency (radiation efficiency and system efficiency) can also improve the antenna directivity. Therefore, although the polarization characteristic of the radiation generated by the antenna 200 is linear polarization when the electronic device 10 communicates in the first frequency band, and there will be a 3dB loss when receiving circularly polarized electromagnetic waves, the antenna 200 has good efficiency (radiation efficiency and system efficiency), and correspondingly, it also has good directivity.

[0250] Simultaneously, when the first radiator 211 generates a second resonance in DM mode, it can excite the third radiator 213 to generate a first parasitic resonance. In one embodiment, when the first feed circuit 221 feeds in an electrical signal, at the resonance point of the second resonance, the current on the first radiator 211 and the current on the third radiator 213 are in the same direction, which can extend the path of the current generated by the first radiator 211, achieving an effect similar to current arraying, and improving the directivity of the antenna 200. The third radiator 213 improves the directivity of the antenna 200, increasing the energy radiated by the antenna 200 towards the top of the electronic device 10 (e.g., in the y-direction), thus allowing the user to perform satellite navigation or communication using the electronic device 10 in the first frequency band without changing their grip on the electronic device 10, resulting in a better user experience.

[0251] In one embodiment, the frequency difference between the resonant point of the second resonance and the resonant point of the first resonance is greater than or equal to 100MHz and less than or equal to 300MHz.

[0252] It should be understood that the first radiator 211 can generate a first resonance (CM mode) and a second resonance (DM mode) using CM mode and DM mode, respectively. When the frequency difference between the resonant point of the second resonance and the resonant point of the first resonance is greater than or equal to 100MHz and less than or equal to 300MHz, the proportion of DM mode in the second resonance can be increased. Therefore, the antenna 200 mainly radiates in the DM mode in the resonant frequency band of the second resonance, thereby improving the radiation efficiency and system efficiency of the antenna 200 in the first frequency band. When the frequency difference between the resonant point of the second resonance and the resonant point of the first resonance is greater than 300MHz, the proportion of other operating modes (e.g., CM mode) in the second resonance increases, leading to a decrease in the radiation efficiency and system efficiency of the antenna 200 in the first frequency band.

[0253] In one embodiment, the frequency difference between the resonant point of the second resonance and the resonant point of the first parasitic resonance is greater than 0 MHz and less than or equal to 200 MHz.

[0254] It should be understood that when the frequency difference between the resonant point of the second resonance and the resonant point of the first parasitic resonance is greater than 0MHz and less than or equal to 200MHz, the electrical signal fed into the first feed circuit 221 will have a greater proportion of current in the same direction as the current on the first radiator 211 at the resonant point of the second resonance, which can further improve the directivity of the antenna 200.

[0255] In one embodiment, the distance between the first radiator 211 and the third radiator 213 can be greater than and equal to two-tenths of the first wavelength and less than or equal to half of the first wavelength, where the first wavelength is the vacuum wavelength corresponding to the first frequency band.

[0256] Correspondingly, the first radiator 211 can operate in half-wavelength mode, and the distance between the first radiator 211 and the third radiator 213 can be greater than and equal to four-tenths of the length L1 of the border between the first position 201 and the second position 202 and less than or equal to the length L1 of the border between the first position 201 and the second position 202.

[0257] It should be understood that when the distance between the first radiator 211 and the third radiator 213 is within the aforementioned range, the directivity of the antenna 200 is improved better. The distance between the first radiator 211 and the third radiator 213 can be understood as the distance between the center (geometric center) of the first radiator 211 and the center of the third radiator 213.

[0258] In one embodiment, the first position 201 and the second position 202 are symmetrical along the virtual axis of the second side 132, and the lengths of the second sides on both sides of the virtual axis are the same.

[0259] It should be understood that as the symmetry of the first radiator 211 increases, the radiation characteristics of the antenna 200 become better.

[0260] In one embodiment, the third position 203 may be located on the first side 131.

[0261] It should be understood that the third position 203 can be located on the first side 131 or the second side 132, and can generate a current in the same direction as the current on the first radiator 211. It can be determined according to the internal layout of the actual electronic device, and the embodiments of this application do not limit this.

[0262] In one embodiment, the second radiator 212 is used to generate a second parasitic resonance, the resonant frequency of which is higher than that of the second resonance.

[0263] It should be understood that the second radiation 212 can improve the radiation efficiency and system efficiency of the antenna 200 in the resonant frequency band of the second resonance, so that the antenna 200 has better radiation characteristics in the first frequency band.

[0264] In one embodiment, the frequency difference between the resonant point of the second parasitic resonance and the resonant point of the second resonance is greater than or equal to 200MHz and less than or equal to 500MHz.

[0265] It should be understood that, since the ends of the radiators on both sides of the second position 202 are open, the coupling between the first radiator 211 and the second radiator 212 is strong when the first feed circuit 221 feeds in an electrical signal. Therefore, there is a certain frequency gap between the resonant point of the second parasitic resonance generated by the second radiator 212 and the resonant point of the second resonance generated by the first radiator 211. When the frequency difference between the resonant points of the second parasitic resonance and the second resonance is greater than or equal to 200MHz and less than or equal to 500MHz, the radiation efficiency and system efficiency of the antenna 200 in the first frequency band are significantly improved.

[0266] In one embodiment, the first radiator 211 further includes a first connection point 2111 and a second connection point 2112. The first connection point 2111 is located between the first position 201 and the first feed point 231 (including the first position 201 and the first feed point 231; in the following embodiments, it is located between A and B, both including A and B). It should be understood that in this embodiment, the feed circuit can be coupled to the feed point via a feed element. When the feed point coincides with the connection point, both the switch and the feed circuit can be coupled to the radiator (feed point / connection point) via the feed element. The second connection point 2112 is located between the second position 202 and the first feed point 231. The electronic device 10 further includes a first switch 251 and a second switch 252. The common port of the first switch 251 is coupled to the first connection point 2111, and the common port of the second switch 252 is coupled to the second connection point 2112.

[0267] It should be understood that the first switch 251 and the second switch 252 can be used to adjust the resonant frequency of the resonance generated by the first radiator 211. When the first switch 251 and the second switch 252 are in different switching states, the first radiator 211 can be used to generate different resonances. In one embodiment, when the first switch 251 is in the first switching state and the second switch 252 is in the second switching state, the first radiator 211 can be used to generate the first resonance and the second resonance. When the first switch 251 is in the third switching state and the second switch 252 is in the fourth switching state, the first radiator 211 can be used to generate the third resonance (CM mode) and the fourth resonance (DM mode). The resonant frequency of the third resonance is lower than that of the fourth resonance, and the resonant frequency of the third resonance is higher than that of the first resonance. The resonant frequency of the fourth resonance is higher than that of the second resonance, and the resonant frequency band of the fourth resonance includes the second frequency band.

[0268] It should be understood that the switching state of the above-mentioned switch can be understood as the electrical connection relationship between the common port (the first port, which can be understood as the port through which the switch is coupled to the radiator) and the connection port. In one embodiment, the first switching state may be that the common port and the connection port are disconnected and not electrically connected. Alternatively, in one embodiment, the first switching state may be that the common port and the connection port are short-circuited and electrically connected. In one embodiment, the connection port may be directly grounded, or at least one electronic component may be electrically connected between the connection port and the ground. Alternatively, in one embodiment, the switch includes multiple common ports, and the first switching state may be that at least some of the multiple common ports are short-circuited and electrically connected to the multiple connection ports. The switching states in the above embodiments can all be understood accordingly, and the embodiments of this application do not limit this, and can be adjusted according to actual production or design.

[0269] In one embodiment, the first switch 251 or the second switch 252 may be a single pole four throw (SPFT). It should be understood that in the embodiments of this application, the switch may be selected according to actual production or design, or it may be a single pole xthrow (SPXT). The embodiments of this application do not limit this, and the switches in the embodiments of this application can be understood accordingly, only requiring that the number of connection ports of the switch is greater than or equal to the number of electronic components or radio frequency channels that need to be connected.

[0270] It should be understood that when the switch includes multiple common ports, the switch in the embodiments of this application may also be a multi-pole multi-throw (XPXT) switch, or it may be composed of multiple single-pole single-throw (SPST) switches connected in parallel.

[0271] In one embodiment, the length D1 of the border between the first connection point 2111 and the first position 201 and the length L1 of the border between the distance between the first position 201 and the second position 202 satisfy: D1 ≤ L1 × 30%. In one embodiment, D1 ≤ L1 × 10%. In one embodiment, D1 is less than or equal to 3 mm.

[0272] In one embodiment, the length D2 of the border between the second connection point 2112 and the second position 202 and the length L1 of the border between the distance between the first position 201 and the second position 202 satisfy: D2 ≤ L1 × 30%. In one embodiment, D2 ≤ L1 × 10%. In one embodiment, D2 is less than or equal to 3 mm.

[0273] It should be understood that when the first connection point 2111 is located in the region near the first position 201 and the second connection point 2112 is located in the region near the second position 202, the electric field in this region is relatively strong, which makes it easier to adjust the resonant frequency of the resonance generated by the first radiator 211.

[0274] In one embodiment, the first frequency band includes at least a portion of the frequency band from 1980MHz to 2010MHz, and the second frequency band includes at least a portion of the frequency band from 2170MHz to 2200MHz.

[0275] It should be understood that the technical solutions provided in this application can be applied to the Tiantong satellite system or the Beidou satellite system. For example, the first frequency band may include at least a portion of the L-band (1610MHz to 1626.5MHz), and the second frequency band may include at least a portion of the S-band (2483.5MHz to 2500MHz). Alternatively, they can also be applied to other satellite communication systems, and this application does not limit this application.

[0276] In one embodiment, the third radiator 213 may further include a third connection point 2131. The electronic device 10 also includes a third switch 253. The common port of the third switch 253 is coupled to the third connection point 2131.

[0277] It should be understood that the third switch 253 can be used to adjust the resonant frequency of the resonance generated by the third radiator 213 so that the resonant frequency of the resonance generated by the third radiator 213 can be within the aforementioned range as the resonant frequency of the second or fourth resonance generated by the first radiator 211, thereby improving the directivity of the antenna 200.

[0278] In one embodiment, the length D3 of the border between the third connection point 2131 and the third position 203 and the length L2 of the border between the first ground point 241 and the third position 203 satisfy: D3 ≤ L2 × 30%. In one embodiment, D3 ≤ L2 × 10%. In one embodiment, D3 is less than or equal to 3 mm.

[0279] In one embodiment, the second radiator 212 may further include a fourth connection point 2121. The electronic device 10 also includes a fourth switch 254. The common port of the fourth switch 254 is coupled to the fourth connection point 2121.

[0280] It should be understood that the fourth switch 254 can be used to adjust the resonant frequency of the resonance generated by the second radiator 212 so that the resonant frequency of the resonance generated by the second radiator 212 can be within the range of the resonant frequency of the second resonance or the fourth resonance generated by the first radiator 211, thereby improving the radiation efficiency and system efficiency of the antenna 200 in the first frequency band.

[0281] In one embodiment, the length D4 of the border between the third connection point 2131 and the second position 202 and the length L3 of the border between the first ground point 241 and the second position 202 satisfy: D4 ≤ L3 × 30%. In one embodiment, D4 ≤ L3 × 10%. In one embodiment, D4 is less than or equal to 3 mm.

[0282] In one embodiment, since satellite communication and cellular communication are not performed simultaneously, when the electronic device 10 is conducting satellite communication, the third radiator 213 can be used to improve the directivity of the antenna 200, and the second radiator 212 can be used to improve the system efficiency and radiation efficiency of the antenna 200. When the electronic device 10 is not conducting satellite communication, the first radiator 211, the second radiator 212, or the third radiator 213 can be reused as the radiator of the cellular communication antenna.

[0283] In one embodiment, the second radiator 212 may further include a second feed point 232, such as Figure 10 As shown. The electronic device 10 may further include a second power supply circuit 222. The second power supply circuit 222 is coupled to a second power supply point 232. In one embodiment, the second power supply point 232 is located between a fourth connection point 2121 and a first ground point 241.

[0284] In one embodiment, the second feed point 232 and the fourth connection point 2121 coincide. This coincidence can be understood as the second feed circuit 222 and the fourth switch 254 being coupled to the second radiator 212 via the same connecting component. In one embodiment, the third radiator 213 may further include a third feed point 233. The electronic device 10 may also include a third feed circuit 223. The third feed circuit 223 is coupled to the third feed point 233. In one embodiment, the third feed point 233 is located between the third connection point 2131 and the first ground point 241.

[0285] It should be understood that the first radiator 211 can form a first antenna element with the first feed circuit 221. The second radiator 212 can form a second antenna element with the second feed circuit 222, and can operate in quarter-wavelength mode. The third radiator 213 and the third feed circuit 223 form a third antenna element, and can operate in quarter-wavelength mode.

[0286] In one embodiment, the third power supply point 233 coincides with the third connection point 2131.

[0287] In one embodiment, the operating frequency band of the second antenna unit may include 2.4 GHz of WiFi, and / or at least a portion of the sub-6 GHz band, such as the n77 band. In one embodiment, the operating frequency band of the third antenna unit may include at least a portion of the middle band (MB) (1710 MHz–2170 MHz), and / or at least a portion of the high band (HB) (2300 MHz–2690 MHz), such as B1 (1920 MHz–1980 MHz), B3 (1710 MHz–1785 MHz), and B7 (2500 MHz–2570 MHz) in LTE.

[0288] It should be understood that the third switch 253 can also be used to determine the resonant frequency of the resonance generated by the third antenna element, so that the third antenna element can operate in different communication frequency bands. For example, the third switch 253 can be in different switching states, so that different electronic components are electrically connected between the third connection point 2131 and the ground. The fourth switch 254 can also be used to determine the resonant frequency of the resonance generated by the second antenna element, so that the second antenna element can operate in different communication frequency bands. For example, the fourth switch 254 can be in different switching states, so that different electronic components are electrically connected between the fourth connection point 2121 and the ground.

[0289] In one embodiment, antenna 200 may further include a fourth radiator 214. Frame 11 may further include a second ground point 242. A first position 201 is located between the second ground point 242 and a first feed point 231, and frame 11 is grounded at the second ground point 242. The fourth radiator 214 includes at least a portion of the frame between the first position 201 and the second ground point 242.

[0290] It should be understood that the fourth radiator 214 can form a fourth antenna element with the fourth feed circuit 224, can operate in a quarter-wavelength mode, and can be used to extend the communication frequency band of the electronic device 10. In one embodiment, the operating frequency band of the fourth antenna element may include at least a portion of the intermediate frequency (1710MHz-2170MHz), and / or at least a portion of the high frequency (2300MHz-2690MHz), and / or at least a portion of the sub-6GHz frequency band, for example, the n77 band.

[0291] In one embodiment, the fourth radiator 213 may further include a fifth connection point 2131. The electronic device 10 also includes a fifth switch 255. The common port of the fifth switch 255 is coupled to the fifth connection point 2131.

[0292] It should be understood that the fifth switch 255 can be used to adjust the resonant frequency of the resonance generated by the fourth radiator 214, so that the fourth antenna element can operate in different communication frequency bands. For example, the fifth switch 255 can be in different switching states, so that different electronic components are electrically connected between the fifth connection point 2141 and the ground.

[0293] Meanwhile, when electronic device 10 is conducting satellite communication, the fourth antenna unit is not operational. The fifth switch 255 can be in a fifth switch state, for example, the common port of the fifth switch 255 is electrically connected to the connection port, the connection port is directly electrically connected to the ground or electrically connected through a 0-ohm resistor, and the fourth radiator 214 is grounded at the fifth connection point 2141 to prevent the fourth radiator 214 from interfering with satellite communication.

[0294] In one embodiment, the frame 11 may further include a third grounding point 243 located between the first position 201 and the first feed point 231. The frame 11 is grounded at the third grounding point 243. See also... Figure 9B The example shown.

[0295] Figure 9B This is a schematic diagram of an electronic device 10 provided in an embodiment of this application.

[0296] like Figure 9B As shown, the electronic device 10 may include a conductive frame 11, an antenna 200, and a first feed circuit 221.

[0297] The frame 11 also includes a third position 203 and a second grounding point 242. The second position 202 is located between the first position 204 and the third position 203. The second grounding point 242 is located between the second position 202 and the third position 203.

[0298] Antenna 200 includes a second radiator 212 and a third radiator 213. The second radiator 212 is a conductive portion of the frame between the second position 202 and the second ground point 242, and the third radiator 213 is a conductive portion of the frame between the second ground point 242 and the third position 203.

[0299] The frame 11 has a third gap. The frame 11 is coupled to the floor 300 at the second grounding point 242.

[0300] The first end of the second radiator 212 (the end closer to the second position 202) is an open end, and the second end is a grounded end (the end closer to the second grounding point 242). The first end of the third radiator 213 (the end closer to the second grounding point 242) is a grounded end, and the second end is an open end (the end closer to the third position 203).

[0301] The third radiator 213 is used to generate a first parasitic resonance, the resonant frequency of which is lower than the resonant frequency of the first main resonance.

[0302] When the first radiator 211 generates a first primary resonance in DM mode, the third radiator 213 can be excited to generate a first parasitic resonance. In one embodiment, when the first feed circuit 221 feeds in an electrical signal, at the resonance point of the first primary resonance, the current on the first radiator 211 and the current on the third radiator 213 are in the same direction, which can extend the path of the current generated by the first radiator 211, achieving an effect similar to current arraying and improving the directivity of the antenna 200. The third radiator 213 improves the directivity of the antenna 200, increasing the energy radiated by the antenna 200 towards the top of the electronic device 10 (e.g., in the y-direction). This allows users to perform satellite navigation or communication using the electronic device 10 in the first frequency band without changing their grip on the device, thus providing a better user experience.

[0303] In one embodiment, the third radiator 213 may further include a third connection point 2131. The electronic device 10 also includes a third tuning circuit 253. The third tuning circuit 253 is coupled to the third connection point 2131.

[0304] It should be understood that the third tuning circuit 253 can be used to adjust the resonant frequency of the resonance generated by the third radiator 213, so that the third radiator 213 generates the first parasitic resonance and the second parasitic resonance, thereby extending the path of the current generated by the first radiator 211 in the first frequency band and the second frequency band, achieving an effect similar to current array, and improving the directivity of the antenna 200.

[0305] In one embodiment, the length L2 of the border between the second position 202 and the third position 203 and the length L1 of the border between the first position 201 and the second position 202 satisfy: L1×80%≤L2≤L1.

[0306] In one embodiment, the frequency difference between the resonant point of the first primary resonance and the resonant point of the first parasitic resonance is less than or equal to 200 MHz. In another embodiment, the frequency difference between the resonant point of the fourth resonance and the resonant point of the second parasitic resonance is less than or equal to 200 MHz.

[0307] It should be understood that when the frequency difference between the resonant point of the first main resonance (or the second main resonance) and the resonant point of the first parasitic resonance (or the second parasitic resonance) is less than or equal to 200MHz, the electrical signal fed into the first feed circuit 221 will have a greater proportion of current in the same direction as the current on the first radiator 211 at the resonant point of the first main resonance (or the second main resonance), which can further improve the directivity of the antenna 200.

[0308] In one embodiment, the length D3 of the border between the third connection point 2131 and the third position 203 and the length H1 of the border between the second ground point 242 and the third position 203 satisfy: D3 ≤ H1 × 30%. In one embodiment, D3 ≤ H1 × 10%. In one embodiment, D3 is less than or equal to 3 mm.

[0309] In one embodiment, the distance between the first radiator 211 and the third radiator 213 can be greater than and equal to two-tenths of the first wavelength and less than or equal to half of the first wavelength, where the first wavelength is the vacuum wavelength corresponding to the first frequency band. It should be understood that since there is a certain correspondence between the vacuum wavelength and the medium wavelength (conduction wavelength), it can be calculated based on the equivalent dielectric constant of the medium surrounding the radiator, and this can be understood accordingly in the embodiments of this application.

[0310] Correspondingly, the first radiator 211 can operate in half-wavelength mode (corresponding to DM mode), and the distance between the first radiator 211 and the third radiator 213 can be greater than and equal to four-tenths of the length L1 of the conductive portion of the frame between the first position 201 and the second position 202 and less than or equal to the length L1 of the conductive portion of the frame between the first position 201 and the second position 202.

[0311] It should be understood that when the distance between the first radiator 211 and the third radiator 213 is within the aforementioned range, the directivity of the antenna 200 is improved better. The distance between the first radiator 211 and the third radiator 213 can be understood as the distance between the center (geometric center) of the first radiator 211 and the center of the third radiator 213.

[0312] In one embodiment, the third position 203 may be located on the first side 131.

[0313] It should be understood that the third position 203 can be located on the first side 131 or the second side 132, and can generate a current in the same direction as the current on the first radiator 211. It can be determined according to the internal layout of the actual electronic device, and the embodiments of this application do not limit this.

[0314] In one embodiment, the second radiator 212 is used to generate a third parasitic resonance, the resonant frequency of which is higher than the resonant frequency of the first primary resonance.

[0315] It should be understood that the second radiation 212 can improve the radiation efficiency and system efficiency of the antenna 200 in the resonant frequency band of the first main resonance, so that the antenna 200 has better radiation characteristics in the first frequency band.

[0316] In one embodiment, the second radiator 212 may further include a fourth connection point 2121. The electronic device 10 also includes a fourth tuning circuit 254. The fourth tuning circuit 254 is coupled to the fourth connection point 2121.

[0317] It should be understood that the fourth tuning circuit 254 can be used to adjust the resonant frequency of the resonance generated by the second radiator 212, so that the second radiator 212 generates a third parasitic resonance and a fourth parasitic resonance, thereby improving the radiation efficiency and system efficiency of the antenna 200 in the first and second frequency bands.

[0318] In one embodiment, the frequency difference between the resonant point of the third parasitic resonance and the resonant point of the first primary resonance is greater than or equal to 200 MHz and less than or equal to 500 MHz. In another embodiment, the frequency difference between the resonant point of the fourth parasitic resonance and the resonant point of the second primary resonance is greater than or equal to 200 MHz and less than or equal to 500 MHz.

[0319] It should be understood that, since the ends of the radiators on both sides of the second position 202 are open, the coupling between the first radiator 211 and the second radiator 212 is strong when the first feed circuit 221 feeds in an electrical signal. Therefore, there is a certain frequency gap between the resonant point of the parasitic resonance generated by the second radiator 212 and the resonant point of the resonance generated by the first radiator 211. When the frequency difference between the resonant point of the third parasitic resonance (fourth parasitic resonance) and the resonant point of the first main resonance (second main resonance) is greater than or equal to 200MHz and less than or equal to 500MHz, the antenna 200 has a better improvement in radiation efficiency and system efficiency in the first frequency band (second frequency band).

[0320] In one embodiment, the length D4 of the border between the third connection point 2131 and the second position 202 and the length H2 of the border between the second grounding point 242 and the second position 202 satisfy: D4 ≤ H2 × 30%. In one embodiment, D4 ≤ H2 × 10%. In one embodiment, D4 is less than or equal to 3 mm.

[0321] In one embodiment, since satellite communication and cellular communication are not performed simultaneously, when the electronic device 10 is conducting satellite communication, the third radiator 213 can be used to improve the directivity of the antenna 200, and the second radiator 212 can be used to improve the system efficiency and radiation efficiency of the antenna 200. When the electronic device 10 is not conducting satellite communication, the first radiator 211, the second radiator 212, or the third radiator 213 can be reused as the radiator of the cellular communication antenna.

[0322] In one embodiment, the second radiator 212 may further include a second feed point 232, such as Figure 10As shown. The electronic device 10 may further include a second power supply circuit 222. The second power supply circuit 222 is coupled to a second power supply point 232. In one embodiment, the second power supply point 232 is located between the fourth connection point 2121 and the second ground point 242.

[0323] In one embodiment, the length R2 of the second radiator 212 (the length of the frame between the second position 202 and the second grounding point 242) and the length L1 of the frame between the first position 201 and the second position 202 (the first radiator 211) satisfy: L1×35%≤R2≤L1×60%. In one embodiment, the second feed point 232 and the fourth connection point 2121 coincide. This coincidence can be understood as the second feed circuit 222 and the fourth tuning circuit 254 being coupled to the second radiator 212 through the same connecting component.

[0324] In one embodiment, the third radiator 213 may further include a third feed point 233. The electronic device 10 may further include a third feed circuit 223. The third feed circuit 223 is coupled to the third feed point 233. In one embodiment, the third feed point 233 is located between the third connection point 2131 and the second ground point 242.

[0325] In one embodiment, the length R3 of the third radiator 213 (the length of the frame between the third position 203 and the second grounding point 242) and the length L1 of the frame between the first position 201 and the second position 202 (the first radiator 211) satisfy: L1×30%≤R3≤L1×55%.

[0326] It should be understood that the first radiator 211 can form a first antenna with the first feed circuit 221. The second radiator 212 can form a second antenna with the second feed circuit 222. Since the first end of the second radiator 212 (the end closer to the second position 202) is an open end and the second end is a grounded end (the end closer to the second grounding point 242), the second antenna can operate in quarter-wavelength mode (in quarter-wavelength mode, the current and electric field are in the same direction on the radiator, and the current point is near the grounding end and the electric field point is near the open end). The third radiator 213 and the third feed circuit 223 form a third antenna. Since the first end of the third radiator 213 (the end closer to the second grounding point 242) is a grounded end and the second end is an open end (the end closer to the third position 203), the third antenna can operate in quarter-wavelength mode.

[0327] In one embodiment, the third power supply point 233 coincides with the third connection point 2131.

[0328] In one embodiment, the operating frequency band of the second antenna may include at least a portion of the 2.4 GHz band of WiFi, and / or at least a portion of the sub-6 GHz band, such as the n77 band. In one embodiment, the operating frequency band of the third antenna may include at least a portion of the middle band (MB) (1710 MHz–2170 MHz), and / or at least a portion of the high band (HB) (2300 MHz–2690 MHz), such as B1 (1920 MHz–1980 MHz), B3 (1710 MHz–1785 MHz), and B7 (2500 MHz–2570 MHz) in LTE.

[0329] It should be understood that the third tuning circuit 253 can also be used to determine the resonant frequency of the resonance generated by the third antenna, so that the third antenna can operate in different communication frequency bands. For example, the third tuning circuit 253 can be in different circuit states, so that different electronic components are electrically connected between the third connection point 2131 and the ground. The fourth tuning circuit 254 can also be used to determine the resonant frequency of the resonance generated by the second antenna, so that the second antenna can operate in different communication frequency bands. For example, the fourth tuning circuit 254 can be in different circuit states, so that different electronic components are electrically connected between the fourth connection point 2121 and the ground.

[0330] Simultaneously, both the second radiator 212 and the third radiator 213 resonate when the electronic device 10 is conducting satellite communication or not. When the electronic device 10 is conducting satellite communication, the second and third antennas do not operate as main feed antennas (e.g., the connection between the antenna and the corresponding feed source is cut off, or the corresponding feed source of the antenna is turned off). The second radiator 212 and the third radiator 213 generate parasitic resonance through indirect coupling with the first radiator 211, thereby improving the radiation characteristics of the antenna 200 (e.g., the frequency difference between the resonant point of the parasitic resonance and the resonant point of the main resonance is within the aforementioned range). When the electronic device 10 is not conducting satellite communication, the second and third antennas can operate as main feed antennas. The second radiator 212 and the third radiator 213 can resonate with the separately fed electrical signals, and the resonant frequency of this resonance is different from the resonant frequency of the parasitic resonance.

[0331] In the embodiments of this application, the electronic device 10 does not perform satellite communication, which can be understood as the antenna 200 being disconnected from the corresponding feed source (e.g., a satellite communication chip or module), or the corresponding feed source (e.g., a satellite communication chip or module) of the antenna 200 being turned off. It should be understood that when the electronic device 10 is not performing satellite communication, the electronic device can perform cellular communication or data communication transmission via WiFi, etc.

[0332] In one embodiment, the antenna 200 may further include a fourth radiator 214. The frame 11 may further include a third ground point 243. A first position 201 is located between the third ground point 243 and a first ground point 241, and the frame 11 is coupled to the ground 300 at the third ground point 243. The fourth radiator 214 is a conductive portion of the frame between the first position 201 and the third ground point 243.

[0333] In one embodiment, the length R4 of the fourth radiator 214 (the length of the frame between the first position 201 and the third grounding point 243) and the length L1 of the frame between the first position 201 and the second position 202 (the first radiator 211) satisfy: L1×40%≤R4≤L1×85%.

[0334] It should be understood that the fourth radiator 214 can form a fourth antenna with the fourth feed circuit 224, can operate in a quarter-wavelength mode, and can be used to extend the communication frequency band of the electronic device 10. In one embodiment, the operating frequency band of the fourth antenna may include at least a portion of the intermediate frequency (1710MHz-2170MHz), and / or, at least a portion of the high frequency (2300MHz-2690MHz), and / or, at least a portion of the sub-6GHz frequency band, for example, the n77 band).

[0335] In one embodiment, the fourth radiator 214 may further include a fifth connection point 2141. The electronic device 10 also includes a fifth tuning circuit 255. The fifth tuning circuit 255 is coupled to the fifth connection point 2141.

[0336] It should be understood that the fifth tuning circuit 255 can be used to adjust the resonant frequency of the resonance generated by the fourth radiator 214, so that the fourth antenna can operate in different communication frequency bands. For example, the fifth tuning circuit 255 can be in different tuning circuit states, so that different electronic components are electrically connected between the fifth connection point 2141 and the ground.

[0337] Meanwhile, the fourth antenna is not operational when the electronic device 10 is conducting satellite communication. The fifth tuning circuit 255 can be in different circuit states; for example, the fifth tuning circuit 255 can be directly electrically connected to the ground or electrically connected through a 0-ohm resistor. The fourth radiator 214 is directly coupled to the ground 300 at the fifth connection point 2141 to prevent the fourth radiator 214 from interfering with satellite communication.

[0338] When the electronic device 10 is engaged in satellite communication, the fourth antenna does not operate as a main feed antenna, and the fourth radiator 214 may not generate a working resonance, or may generate a parasitic working resonance through indirect coupling. When the electronic device 10 is not engaged in satellite communication, the fourth antenna can operate as a main feed antenna, and the fourth radiator 214 can generate resonance from the fed electrical signal.

[0339] In one embodiment, the frame 11 may further include a third grounding point 243 located between the first position 201 and the first power supply point 231. The frame 11 is grounded at the third grounding point 243.

[0340] It should be understood that the third grounding point 243 can be used to improve the isolation between the second and fourth antennas. Furthermore, when the fourth antenna is operational, the fourth radiator 214 acts as the main radiating stub (including the fourth feed point 234), and the frame between the fourth grounding point 244 and the first position 201 can act as a parasitic stub of the fourth antenna, used to improve its radiation characteristics. The first tuning circuit 251 can be in different circuit states, and different electronic components are electrically connected between the first connection point and the ground plane, allowing the parasitic stub to generate resonances at different frequencies.

[0341] Correspondingly, the first antenna, with the frame between the second position 202 and the first ground point 241 serving as the main radiating stub, can operate in quarter-wavelength mode. The second tuning circuit 252 can also be used to determine the resonant frequency of the resonance generated by the first antenna, so that the first antenna can operate in different communication frequency bands. For example, the second tuning circuit 252 can be in different tuning circuit states, so that different electronic components are electrically connected between the second connection point and the ground.

[0342] In one embodiment, the operating frequency band of the first antenna may include the L1 band in GPS, and / or at least a portion of the sub 6G frequency band, such as the n79 band.

[0343] In one embodiment, the L1 band in GPS may include 1575.42MHz ± 1.023MHz. In another embodiment, sub 6G may include the n77 band and the n79 band. The n77 band may include 3300MHz-4200MHz. The n79 band may include 4400MHz-5000MHz.

[0344] It should be understood that when the first antenna operates in the L1 band of GPS, since the L1 band of GPS is incompatible with the frequency band of satellite communication (cannot be shared for matching), the electronic device 10 may also include a switch coupled between the first feed point 231 and the ground. When the electronic device 10 is performing satellite communication, the first antenna is not working, and the switch is open (or, the first feed point 231 and the ground are equivalently open circuits, for example, the equivalent inductance between the first feed point 231 and the ground is greater than 20nH). When the first antenna operates in the L1 band of GPS, the switch is closed, and electronic components may be electrically connected between the second tuning circuit and the ground to match the L1 band.

[0345] Simultaneously, the first radiator 211 resonates whether the electronic device is conducting satellite communication or not. When the electronic device 10 is conducting satellite communication, the first antenna does not operate as a main feed antenna, and the stub of the first radiator 211 (the frame between the first position 201 and the second position 202) generates a first main resonance and a second main resonance. When the electronic device 10 is not conducting satellite communication, the first antenna can operate as a main feed antenna, and a portion of the stub of the first radiator 211 (the frame between the second position 202 and the first ground point 241) resonates, the resonant frequency of which is different from the resonant frequency of the first main resonance or the resonant frequency of the second main resonance. For example, when the electronic device 10 is not conducting satellite communication, the first antenna can operate as a GPS antenna to enable the electronic device to perform GPS positioning.

[0346] In one embodiment, at least one of the L1 and L5 frequency bands of GPS can be supported by any one of the second, third, and fourth antennas described above, and the fifth and sixth antennas described below. For example, signals from at least one of the L1 and L5 frequency bands of GPS can be radiated via the second feed circuit 222 and the second radiator 212, or via the third feed circuit 223 and the third radiator 213. It should be understood that since the L1 frequency band of GPS includes 1575.42MHz ± 1.023MHz and the L5 frequency band of GPS includes 1176.45MHz, there is a frequency difference with the satellite communication frequency band in the embodiments of this application, and the electronic device in this application can also perform satellite communication and GPS satellite navigation simultaneously.

[0347] In one embodiment, grounding can be achieved at the first grounding point 241 via a first grounding element. The width of the first grounding element connected to the frame is greater than or equal to 2 mm and less than or equal to 8 mm, so as to provide better isolation between the second antenna and the fourth antenna.

[0348] It should be understood that the grounding point and / or connection point can be achieved through a metal spring or a connecting rib structure between the metal spring and the middle plate of the middle frame. When using metal components such as metal springs, the distance between the grounding point and / or connection point and other points or ends on the radiator can be understood as the distance measured from the center of the metal spring. When using a connecting rib structure between the metal spring and the middle plate of the middle frame, the distance between the grounding point and / or connection point and other points or ends on the radiator can be understood as the distance measured from the edge of one end of the connecting rib structure.

[0349] In one embodiment, the electronic device includes the aforementioned mid-frame, which includes the aforementioned frame 11 and mid-plate. In one embodiment, the mid-plate is electrically connected to the floor 300 at multiple points. In one embodiment, the mid-plate can be considered as part of the floor 300. In one embodiment, the frame 11 and the mid-plate are electrically connected by a connecting structure (e.g., a first grounding element, not shown in the figure). The connecting structure (e.g., a first grounding element, not shown in the figure) connects between the frame and the mid-plate and is integrally formed with the frame and the mid-plate. For the sake of brevity, the grounding element described in the embodiments of this application can be understood accordingly.

[0350] In one embodiment, the first grounding element extends for a length less than or equal to 6 mm between the frame and the floor.

[0351] In one embodiment, an electronic component is coupled between the first grounding element and the ground plane, and the equivalent capacitance of the electronic component is greater than or equal to 3pF.

[0352] It should be understood that when electronic device 10 operates in the satellite frequency band, the electronic components are in an open state in at least a portion of the frequency bands of the satellite system (at least a portion of the frequency bands of the Tiantong satellite system and / or at least a portion of the frequency bands of the Beidou satellite system), which can make the first grounding component and the ground essentially in an open circuit state. In this application, "open circuit state" refers to the current state between the first grounding component and the ground. For example, in the "open circuit state," the current distributed on the first radiator 211 and the ground is essentially not coupled / flowing through the first grounding component and the electronic component. It should be understood that "the current is essentially not coupled / flowing" should not be interpreted absolutely. In the embodiments of this application, when electronic device 10 operates in the satellite frequency band, the first radiator 211 can generate a line DM mode through the arrangement of the electronic components. Therefore, it can be considered that the electronic component is in an open state in at least a portion of the frequency bands of the satellite system, and the current is essentially not coupled / flowing through the first grounding component and the electronic component. In one embodiment, the radiation efficiency and system efficiency of the resonance generated by the line DM mode of antenna 200 are relatively high.

[0353] When electronic device 10 is not operating in the satellite frequency band, the electronic components are in a conductive state in the operating frequency band of the second antenna and / or the fourth antenna, which can make the first grounding element and the ground approximately short-circuited. In this application, "short-circuit state" refers to the current state between the first grounding element and the ground. For example, in the "short-circuit state," the current distributed on the first radiator 211 and the ground is substantially coupled / flows through the first grounding element and the electronic component. In one embodiment, the first radiator 211 is coupled to the ground through the first grounding element and the electronic component, which can provide better isolation between the second antenna and the fourth antenna. It should be understood that the open ends of the second antenna and the fourth antenna are located on opposite sides of the first grounding element, and the good isolation between them is achieved through the current short-circuit state at the first grounding element.

[0354] The electronic components can also be used to adjust the electrical length of the radiator. In one embodiment, the electronic components can be used to adjust the electrical length of the conductor portion between the first position 201 and the first ground point 241, or the electrical length of the conductor portion between the second position 202 and the first ground point 241.

[0355] For the sake of brevity, the structures of the grounding components in the embodiments of the application can all be understood accordingly, and will not be described in detail here.

[0356] In one embodiment, a series-connected electronic switch is coupled between the first grounding element and the ground plane. The switch can be used to control the electrical connection state between the first grounding element and the ground plane.

[0357] It should be understood that when electronic device 10 operates in the satellite frequency band, the switch is in the open state, which disconnects the first grounding element from the ground and prevents the first radiator 211 from being coupled to the ground. The first radiator 211 only generates the line DM mode, and the antenna 200 has higher radiation efficiency and system efficiency due to the resonance generated by the line DM mode. When electronic device 10 does not operate in the satellite frequency band, the switch is in the closed state, which short-circuits the first grounding element from the ground and couples the first radiator 211 to the ground, resulting in better isolation between the second antenna and the fourth antenna.

[0358] In one embodiment, the first grounding element may include a first spring and a second spring, and electronic components are coupled between the first spring, the second spring, and the ground, with each electronic component having an equivalent capacitance value greater than or equal to 3pF.

[0359] In one embodiment, when the first grounding element is connected to the floor via electronic components, the width of the first grounding element may be greater than or equal to 1.5 mm and less than or equal to 12 mm. In another embodiment, the width of the first grounding element may be greater than or equal to 2 mm and less than or equal to 8 mm.

[0360] It should be understood that when the first grounding component is coupled to the ground via electronic components, the width of the first grounding component can be understood as the distance (length of the frame) between the midpoint of the end of the first spring piece coupled to the first radiator 211 and the midpoint of the end of the second spring piece coupled to the first radiator 211. For the sake of brevity, this embodiment of the application only uses the example of the first grounding component including two spring pieces for illustration. In actual production or design, it may also include multiple spring pieces (multiple spring pieces are coupled to the ground to connect electronic components). The first spring piece and the second spring piece can be understood as the two spring pieces that are furthest apart among the multiple spring pieces.

[0361] In one embodiment, when the first grounding element is coupled to the floor via electronic components, the electronic device 10 may further include a SAR sensor. The SAR sensor may be electrically connected between the electronic components and the floor, with the first radiator 211 serving as the sensing element. The SAR sensor is used to determine the distance between a human body and the electronic device 10 (the first radiator 211).

[0362] In one embodiment, when the SAR sensor is electrically connected between the electronic components and the floor, the equivalent capacitance of all electronic components electrically connected to the first radiator 211 is less than or equal to 120 pF, so that the SAR sensor has a good working condition.

[0363] In one embodiment, when electronic components are coupled between the first grounding element and the ground plane, the frequency difference between the resonant point of the second resonance and the resonant point of the first resonance, and / or the frequency difference between the resonant point of the fourth resonance and the resonant point of the third resonance, can be determined based on the center frequency of the operating frequency band of the antenna 200.

[0364] In one embodiment, the center frequency of the operating frequency band of antenna 200 is greater than or equal to 1 GHz and less than 2.5 GHz. For example, this operating frequency band includes at least a portion of the frequency bands in the Tiantong satellite system and at least a portion of the frequency bands in the Beidou satellite system. The frequency difference between the resonant point of the second resonance and the resonant point of the first resonance is less than or equal to 500 MHz, and / or, the frequency difference between the resonant point of the fourth resonance and the resonant point of the third resonance is less than or equal to 500 MHz. The frequency difference between the resonant point of the second resonance and the resonant point of the first resonance is greater than or equal to 50 MHz, and / or, the frequency difference between the resonant point of the fourth resonance and the resonant point of the third resonance is greater than or equal to 50 MHz.

[0365] In one embodiment, the center frequency of the operating frequency band of antenna 200 is greater than or equal to 2.5 GHz and less than or equal to 5 GHz, for example, this operating frequency band includes at least a portion of the frequency bands in other systems. The frequency difference between the resonant point of the second resonance and the resonant point of the first resonance is less than or equal to 1200 MHz, and / or, the frequency difference between the resonant point of the fourth resonance and the resonant point of the third resonance is less than or equal to 1200 MHz. The frequency difference between the resonant point of the second resonance and the resonant point of the first resonance is greater than or equal to 100 MHz, and / or, the frequency difference between the resonant point of the fourth resonance and the resonant point of the third resonance is greater than or equal to 100 MHz. In one embodiment, grounding can be achieved at the second grounding point 242 via a second grounding element. The width of the connection between the second grounding element and the frame is greater than or equal to 2 mm and less than or equal to 12 mm.

[0366] It should be understood that setting a grounding structure at the second grounding point 242 can be used to improve the isolation between the second antenna and the third antenna.

[0367] In one embodiment, when the first feed point 231 is located between the second end (second position 202) and the first ground point 241, the portion of the first radiator 211 between the first end (first position 201) and the first ground point 241 can also serve as a radiator. This radiator can be coupled to the feed circuit as another antenna. This antenna can be used to expand the communication frequency band of electronic devices.

[0368] Figures 11 to 15 yes Figure 10 The simulation results for antenna 200 are shown. Among them, Figure 11 yes Figure 10 The simulation results of the S-parameters of antenna 200 are shown. Figure 12 yes Figure 10 The simulation results show the system efficiency and radiation efficiency of the antenna 200. Figure 13 yes Figure 10 The diagram shows the current distribution of antenna 200 operating in quarter-wavelength mode at 2.2 GHz. Figure 14 yes Figure 10 The diagram shows the current distribution of antenna 200 operating in CM mode at 2.2 GHz. Figure 15 yes Figure 10 The diagram shows the current distribution of antenna 200 operating in DM mode at 2.2 GHz.

[0369] It should be understood that, Figures 11 to 15Simulation results for the first radiator in different operating modes are shown. The third, fourth, and fifth connection points are grounded (the third, fourth, and fifth connection points are either directly electrically connected to the ground via the third, fourth, and fifth tuning circuits or electrically connected via a 0-ohm resistor) to prevent the second, third, and fourth radiators from affecting the first radiator. Correspondingly, the first and second tuning circuits are in different circuit states (e.g., electrically connected to different electronic components) to allow the first radiator to operate in different modes at 2.2 GHz.

[0370] For the sake of brevity, this application embodiment will only be described with the example of the first radiator forming a structure similar to a left-handed antenna (the length of the frame between the first feed point and the second position is less than half the length of the frame (conductor portion) between the second position and the first ground point) and operating in the quarter-wavelength mode of a left-handed antenna. The left-handed antenna can be, for example, an antenna conforming to a composite right and left hand (CRLH) transmission line structure.

[0371] When the first radiator operates in quarter-wavelength mode, the first connection point is grounded (either directly electrically connected to the ground via a first tuning circuit or electrically connected via a 0-ohm resistor). The border between the first ground point and the first location acts as a grounding branch and does not participate in radiation. When the first radiator operates in CM or DM mode, the first and second tuning circuits are in different circuit states (e.g., different electronic components are electrically connected between the connection point and the ground), so that 2.2 GHz corresponds to CM and DM modes, respectively.

[0372] like Figure 11 As shown, the first radiator can resonate at 2.2 GHz in quarter-wavelength mode, CM mode and DM mode.

[0373] like Figure 12 As shown, the system efficiency and radiation efficiency of the DM mode are approximately 0.5 dB higher than those of the quarter-wavelength mode. The system efficiency and radiation efficiency of the quarter-wavelength mode are also approximately 0.5 dB higher than those of the CM mode.

[0374] like Figure 13 As shown, the border between the second position and the first ground point can correspond to the quarter-wavelength mode described above.

[0375] like Figure 14As shown, when the first radiator resonates, the current in the CM mode on the radiator can excite the transverse mode on the floor, but the currents generated by the transverse mode will cancel each other out, resulting in low system efficiency and radiation efficiency for the CM mode.

[0376] like Figure 15 As shown, when the first radiator resonates, it mainly radiates from the frame between the first and second positions. Furthermore, it can excite the lateral modes on the floor, and since the currents generated by the lateral modes are in the same direction and do not cancel each other out, the system efficiency and radiation efficiency of the DM mode are relatively high.

[0377] When the first frame is located at the center of the second frame, it can excite the lateral mode (which accounts for more than the vertical mode), but the currents corresponding to the lateral modes will cancel each other out. Therefore, the system efficiency and radiation efficiency of the CM mode are low.

[0378] Figures 16 to 19 yes Figure 10 The diagram shows the current and electric field distribution of antenna 200 (back view). Figure 16 yes Figure 10 The diagram shows the current distribution of the antenna 200 when it is grounded at the third connection point 2131 (back view). Figure 17 yes Figure 10 The diagram shows the current distribution of the antenna 200 when the third connection point 2131 is not grounded (back view). Figure 18 yes Figure 10 The diagram shows the electric field distribution of the antenna 200 when it is grounded at the third connection point 2131 (back view). Figure 19 yes Figure 10 The diagram shows the electric field distribution of the antenna 200 when the third connection point 2131 is not grounded (back view).

[0379] It should be understood that Figures 16 to 19 This diagram illustrates the current formation between the third radiator and the first radiator within one current cycle T at 2.2 GHz, resembling an array. The fourth and fifth connection points are grounded (either directly electrically connected to the ground via the fourth and fifth tuning circuits or via a 0-ohm resistor) to prevent the second and fourth radiators from affecting the current and electric field distribution. The first and second tuning circuits are in their corresponding tuning states to ensure the first radiator operates in DM mode at 2.2 GHz.

[0380] like Figure 16As shown, the diagram illustrates the current distribution when the third connection point is grounded (either directly electrically connected to the ground via the third tuning circuit or electrically connected via a 0-ohm resistor), and the third radiator can act as a grounded branch and does not participate in radiation. The current is mainly concentrated on the first radiator.

[0381] like Figure 17 The diagram shows a schematic of the current distribution in a circuit where electronic components are electrically connected between the third tuning circuit and the ground (the resonant frequency of the first parasitic resonance generated by the third radiator is lower than the resonant frequency of the first resonance generated by the first radiator). At the resonant point of the second resonance (2.2 GHz), the currents on the first and third radiators are in the same direction, and the path of the current generated by the first radiator is extended.

[0382] like Figure 18 As shown, when the third radiator is a grounded branch, the electric field near the third radiator is weak.

[0383] like Figure 19 As shown, when an electronic component is electrically connected between the third tuning circuit and the ground (the resonant frequency of the first parasitic resonance generated by the third radiator is lower than the resonant frequency of the first resonance generated by the first radiator), the electric field near the third radiator is stronger.

[0384] Figures 20 to 23 yes Figure 10 The simulation results of the radiation pattern of antenna 200 are shown. Figure 20 yes Figure 10 The directional gain pattern of the antenna 200 shown is grounded at the third connection point. Figure 21 yes Figure 10 The antenna 200 shown is a left-hand circular polarization directional pattern when it is grounded at the third connection point. Figure 22 yes Figure 10 The directional gain pattern of the antenna 200 shown is when the third connection point is not grounded. Figure 23 yes Figure 10 The antenna 200 shown is a left-hand circular polarization directional pattern when the third connection point is not grounded.

[0385] It should be understood that Figures 20 to 23 The simulation results of the radiation patterns shown are all simulation results when the electronic device is set on the human hand model.

[0386] like Figure 20 As shown, when the third radiator is a grounded stub, the antenna's directional gain is 4.05 dBi. The maximum radiation direction of the antenna's radiation deviates from the top of the electronic device (e.g., the y-direction).

[0387] like Figure 21As shown, when the third radiator is a grounded stub, the antenna's left-hand circular polarization directional gain is 1.1 dBic.

[0388] like Figure 22 As shown, when an electronic component is electrically connected between the third tuning circuit and the ground (the resonant frequency of the first parasitic resonance generated by the third radiator is lower than the resonant frequency of the first resonance generated by the first radiator), since the currents on the first radiator and the third radiator are in the same direction, the currents between the third radiator and the first radiator form a similar array, compared to... Figure 20 The gain pattern shown shows that the maximum radiation direction of the antenna is closer to the top of the electronic device (e.g., the y-direction), and the directional gain is increased from 4.05 dBi to 4.8 dBi.

[0389] like Figure 23 As shown, when electronic components are electrically connected between the third tuning circuit and the ground, the left-hand circular polarization directional gain of the antenna increases from 1.1 dBic to 1.9 dBic.

[0390] Figure 24 and Figure 25 Yes, yes Figure 10 The simulation results for antenna 200 are shown. Among them, Figure 24 yes Figure 10 The simulation results of the S-parameters of antenna 200 are shown. Figure 25 yes Figure 10 The simulation results show the system efficiency and radiation efficiency of the antenna 200.

[0391] It should be understood that Figure 24 and Figure 25 Simulation results of the antenna are shown when the first and second tuning circuits are in different circuit states. For example, when the first and second tuning circuits are in the first circuit state (e.g., a first electronic component is electrically connected between the connection point and the ground), the resonances generated by the antenna include a first resonance and a second resonance. When the first and second tuning circuits are in the second circuit state (e.g., a second electronic component is electrically connected between the connection point and the ground), the resonances generated by the antenna include a third resonance and a fourth resonance.

[0392] Correspondingly, the third tuning circuit can be in the first circuit state and the second circuit state when the first radiator generates the second resonance and the fourth resonance, respectively, so that the resonant frequency of the parasitic resonance generated by the third radiator is within the range described in the above embodiments, thereby improving the directivity of the antenna.

[0393] Furthermore, the fourth tuning circuit can be in the first circuit state and the second circuit state when the first radiator generates the second resonance and the fourth resonance, respectively, so that the resonant frequency of the parasitic resonance generated by the fourth radiator is within the range described in the above embodiments, thereby improving the radiation efficiency of the antenna and the system efficiency.

[0394] It should be understood that antenna gain is related to antenna directivity and efficiency (radiation efficiency and system efficiency). Therefore, increasing antenna efficiency (radiation efficiency and system efficiency) while maintaining directivity can also increase antenna gain.

[0395] The fifth tuning circuit can make the fifth connection point directly electrically connected to the ground or electrically connected through a 0-ohm resistor. The fourth radiator is coupled to the ground at the fifth connection point to prevent the fourth radiator from interfering with satellite communications.

[0396] like Figure 24 As shown, when an electrical signal is fed into the first feeding circuit, the antenna can generate two resonances when the first tuning circuit and the second tuning circuit are in different circuit states. When the first tuning circuit and the second tuning circuit are in the first circuit state, the resonance generated by the antenna includes a first resonance (around 1.7 GHz) and a second resonance (around 2 GHz). With S11 < -6 dB as the boundary, the operating frequency band of the antenna can include 1980 MHz - 2010 MHz.

[0397] When the first and second tuning circuits are in the second circuit state, the resonance generated by the antenna includes the third resonance (around 2GHz) and the fourth resonance (around 2.2GHz). With S11 < -6dB as the boundary, the operating frequency band of the antenna can include 2170MHz-2200MHz.

[0398] like Figure 25 As shown, since the first radiator operates in DM mode in the 1980MHz-2010MHz and 2170MHz-2200MHz bands, and the third radiator can improve the system efficiency and radiation efficiency of the antenna, the antenna has good system efficiency and radiation efficiency in the above frequency bands.

[0399] Figure 26 This is a schematic diagram of another electronic device 10 provided in the embodiments of this application.

[0400] like Figure 26As shown, the frame 11 may further include a fourth position 204, with a third grounding point 243 located between the first position 201 and the fourth position 204, and the fourth position 204 having a fourth slot. The antenna 200 also includes a fifth radiator 215, which includes at least a portion of the frame between the third grounding point 243 and the fourth position 204. The fifth radiator 215 is used to generate a third parasitic resonance, the resonant frequency of which is lower than the resonant frequency of the first main resonance.

[0401] It should be understood that Figure 26 The electronic device 10 shown is Figure 10 The only difference in the electronic device 10 shown is that a fourth slit is opened at the fourth position 204 so that the antenna 200 includes a fifth radiator 215.

[0402] In the technical solution provided in this application embodiment, when the first radiator 211 generates the first main resonance in the line DM mode, the fifth radiator 215 can be excited to generate the fifth parasitic resonance. In one embodiment, when the first feed circuit 221 feeds in an electrical signal, at the resonance point of the first main resonance, the current on the first radiator 211 and the current on the fifth radiator 215 are in the same direction, which can extend the path of the current generated by the first radiator 211. The same-direction currents on the first radiator 211, the third radiator 213, and the fifth radiator 215 can achieve a similar effect to current arraying, further improving the directivity of the antenna 200.

[0403] In one embodiment, the length L3 of the border between the first position 201 and the fourth position 204 and the length L1 of the border between the first position 201 and the second position 202 satisfy: L1≤L3≤L1×120%.

[0404] In one embodiment, the fifth radiator 215 may further include a sixth connection point 2151. The electronic device 10 also includes a sixth tuning circuit 256. The sixth tuning circuit 256 is coupled to the sixth connection point 2151.

[0405] It should be understood that the sixth tuning circuit 256 can be used to adjust the resonant frequency of the resonance generated by the fifth radiator 215, so that the fifth radiator 215 generates the fifth parasitic resonance and the sixth parasitic resonance, thereby extending the path of the current generated by the first radiator 211 in the first frequency band and the second frequency band, achieving an effect similar to current array, and improving the directivity of the antenna 200.

[0406] In one embodiment, the frequency difference between the resonant point of the first primary resonance and the resonant point of the fifth parasitic resonance is less than or equal to 200 MHz. In another embodiment, the frequency difference between the resonant point of the second primary resonance and the resonant point of the sixth parasitic resonance is less than or equal to 200 MHz.

[0407] It should be understood that when the frequency difference between the resonant point of the first main resonance (or the second main resonance) and the resonant point of the fifth parasitic resonance (or the sixth parasitic resonance) is less than or equal to 200MHz, the electrical signal fed into the first feed circuit 221 will have a greater proportion of current in the same direction as the current on the first radiator 211 at the resonant point of the first main resonance (or the second main resonance), which can further improve the directivity of the antenna 200.

[0408] In one embodiment, the border 11 may include a third side 133 that intersects the second side 132 at an angle, and the length of the third side 133 is greater than the length of the second side 132. In one embodiment, the fourth position 204 is located on the third side 133.

[0409] In one embodiment, the fifth radiator 215 may further include a fifth feed point 235. The electronic device 10 may further include a fifth feed circuit 225. The fifth feed circuit 225 is coupled to the fifth feed point 235. In one embodiment, the fifth feed point 235 is located between the sixth connection point 2151 and the third ground point 243.

[0410] It should be understood that when antenna 200 is not performing satellite communication, the fifth radiator 215 can form a fifth antenna with the fifth feed circuit 225 and can operate in quarter-wavelength mode.

[0411] In one embodiment, the length R5 of the fifth radiator 215 (the length of the frame between the fourth position 204 and the third grounding point 243) and the length L1 of the frame between the first position 201 and the second position 202 (the first radiator 211) satisfy: L1×40%≤R5≤L1×65%.

[0412] In one embodiment, the operating frequency band of the fifth antenna may include at least a portion of the middle band (MB) (1710MHz-2170MHz), and / or at least a portion of the high band (HB) (2300MHz-2690MHz), such as B1 (1920MHz–1980MHz), B3 (1710MHz–1785MHz), and B7 (2500MHz–2570MHz) in LTE.

[0413] It should be understood that the sixth tuning circuit 256 can also be used to determine the resonant frequency of the resonance generated by the fifth antenna, so that the fifth antenna can operate in different communication frequency bands. For example, the sixth tuning circuit 256 can be in different circuit states, so that different electronic components are electrically connected between the sixth connection point 2151 and the ground.

[0414] Simultaneously, the fifth radiator 215 resonates whether the electronic device is conducting satellite communication or not. When the electronic device 10 is conducting satellite communication, the fifth antenna does not operate as a master feed antenna. The fifth radiator 215 generates parasitic resonance through indirect coupling with the first radiator 211, thereby improving the radiation characteristics of the antenna 200 (for example, the frequency difference between the resonant point of the parasitic resonance and the resonant point of the master resonance is within the aforementioned range). When the electronic device 10 is not conducting satellite communication, the fifth antenna operates as a master feed antenna. The fifth radiator 215 can resonate with the input electrical signal, and the resonant frequency of this resonance is different from the resonant frequency of the parasitic resonance.

[0415] In one embodiment, grounding can be achieved at the third grounding point 243 via a third grounding element. The width of the connection between the third grounding element and the frame is greater than or equal to 1 mm and less than or equal to 20 mm.

[0416] It should be understood that the grounding structure at the third grounding point 243 can be used to improve the isolation between the fourth and fifth antennas.

[0417] In one embodiment, the distance between the third grounding point 243 and the sixth grounding point 246 is greater than or equal to 1 mm and less than or equal to 20 mm, so as to provide better isolation between the fourth antenna and the fifth antenna.

[0418] It should be understood that, for the sake of brevity, this application embodiment only uses the example of the first antenna, second antenna, third antenna, fourth antenna and fifth antenna operating in the above frequency bands. In actual production or design, the operating frequency bands of the first antenna, second antenna, third antenna, fourth antenna and fifth antenna may include other frequency bands, and this application embodiment does not limit this.

[0419] In the embodiments of this application, the first antenna and antenna 200 use the same feeding circuit (first feeding circuit) to feed electrical signals. When the electronic device 10 is performing satellite communication, this feeding circuit cannot feed the electrical signals of the first antenna, therefore, the first antenna does not work. In one embodiment, the first antenna is used to feed signals from the L1 band of GPS, then the antenna 200 for satellite communication and the first antenna for the L1 band of GPS do not work simultaneously. In one embodiment, the first antenna is used to feed signals from the 2.4 GHz band of Wi-Fi, then the antenna 200 for satellite communication and the first antenna for the 2.4 GHz band of Wi-Fi do not work simultaneously. Similarly, the first antenna can also be used to feed signals from other frequency bands, which will not be elaborated here.

[0420] When electronic device 10 performs satellite communication, at least a portion of the operating frequency bands of the second antenna (e.g., the 2.4GHz band or N77 band of WiFi), the third antenna (e.g., MB or HB), the fourth antenna (e.g., MB or HB, N77 band), and the fifth antenna (e.g., MB or HB) are close to the first or second main resonance of antenna 200 (e.g., the difference between the center frequency of a portion of the operating frequency band and the resonant frequency of the main resonance is less than or equal to 200MHz), resulting in poor isolation between the second, third, fourth, and fifth antennas and antenna 200 (e.g., isolation less than 25dB). When antenna 200 resonates and the second, third, fourth, and fifth antennas operate, some power flows from the feed points of the second, third, fourth, and fifth antennas into the corresponding feed circuits, causing damage to some components in the feed circuits.

[0421] In one embodiment, the operating frequency band of the second, third, fourth, or fifth antenna is not close to the first or second main resonance of the antenna 200 (for example, the difference between the center frequency of a portion of the operating frequency band and the resonant frequency of the main resonance is greater than 200MHz). When the electronic device 10 performs satellite communication, the second, third, fourth, or fifth antenna can operate simultaneously with the antenna 200.

[0422] In one embodiment, the operating frequency band of the second, third, fourth, or fifth antenna may include the L1 band of GPS. Since the L1 band in GPS is not adjacent to the frequency bands used in satellite communication and has good isolation, antennas including the L1 band in GPS can operate simultaneously with antenna 200. Electronic device 10 can perform positioning simultaneously while conducting satellite communication (sending or receiving short messages, voice communication).

[0423] In one embodiment, the electronic device 10 may further include antenna 400 and antenna 500, such as Figure 27 As shown.

[0424] The operating frequency band of antenna 400 may include the BT band (2.4GHz-2.4835GHz). The operating frequency band of antenna 500 may include at least a portion of the middle band (MB) (1710MHz-2170MHz), and / or at least a portion of the high band (HB) (2300MHz-2690MHz), for example, B1 (1920MHz–1980MHz), B3 (1710MHz–1785MHz), and B7 (2500MHz–2570MHz) in LTE.

[0425] In one embodiment, the distance between antenna 400 and the first radiator in antenna 200 along the extension direction of the first side 131 or the third side 133 may be greater than one-sixth of the length of the first side 131 or the third side 133. In one embodiment, antenna 400 may be located near the side key of electronic device 10.

[0426] In one embodiment, the distance between the antenna 500 and the first radiator in the antenna 200 along the extension direction of the first side 131 or the extension direction of the third side 133 can be greater than half the length of the first side 131 or the third side 133.

[0427] It should be understood that when the operating frequency band of antenna 400 is close to but does not overlap with the operating frequency band of antenna 200, and the distance between antenna 400 and the first radiator in antenna 200 along the extension direction of the first side 131 or the extension direction of the third side 133 can be greater than one-sixth of the length of the first side 131 or the third side 133, antenna 400 and antenna 200 can have good isolation, and both can work simultaneously. In one embodiment, electronic device 10 can connect to a wearable peripheral device (e.g., headphones or watch) via Bluetooth through antenna 400.

[0428] When the operating frequency band of antenna 500 is close to but does not overlap with the operating frequency band of antenna 200, and the distance between the first radiator of antenna 500 and antenna 200 along the extension direction of the first side 131 or the extension direction of the third side 133 can be greater than half the length of the first side 131 or the third side 133, antenna 500 and antenna 200 can have good isolation and can work simultaneously.

[0429] Figure 28 This is a schematic diagram of the graphical user interface of an electronic device 10 provided in an embodiment of this application.

[0430] It should be understood that, for the sake of brevity, this application embodiment only uses the example of the first antenna, second antenna, third antenna, fourth antenna and fifth antenna operating in the above frequency bands. In actual production or design, the operating frequency bands of the first antenna, second antenna, third antenna, fourth antenna and fifth antenna may include other frequency bands, and this application embodiment does not limit this.

[0431] When electronic device 10 is not performing satellite communication, it can communicate via the first antenna, second antenna, third antenna, fourth antenna, or fifth antenna described in the above embodiments. It can also communicate via 4G / 5G frequency bands in cellular networks, WiFi, and GPS for positioning. Figure 28 As shown in (a) in the figure.

[0432] When a user is ready to engage in satellite communication, they should enable the satellite communication application, such as... Figure 28 As shown in (b) of the diagram.

[0433] It should be understood that, in the embodiments of this application, only... Figure 28 The graphical user interface shown in (b) is used as an example for illustration. In actual production or design, this can also be adjusted.

[0434] When a user enables satellite communication, the graphical user interface reminds the user of the frequency bands that will be turned off, such as... Figure 28 As shown in (c) in the figure.

[0435] It should be understood that when a user enables satellite communication, the electronic device 10 can disable some antennas associated with antenna 200 in the above embodiments. For example, the second antenna (e.g., the 2.4GHz band of WiFi, the N77 band), the third antenna (e.g., MB or HB), the fourth antenna (e.g., MB or HB, the N77 band), and the fifth antenna (e.g., MB or HB) in the above embodiments.

[0436] Meanwhile, some antennas in electronic device 10 may remain on. For example, antennas 400 and 500 in the above embodiments. Electronic device 10 can connect to wearable peripheral devices (e.g., headphones or watches) via Bluetooth through antenna 400. Alternatively, when the operating frequency bands of the second, third, fourth, or fifth antennas in the above embodiments are not adjacent to the first or second main resonance of antenna 200, they can operate simultaneously with satellite communication.

[0437] Once the user activates satellite communication, they can follow the steps displayed in the graphical user interface to connect to the satellite and begin communication. Figure 28 As shown in (d) in the figure.

[0438] Figure 29 This is a schematic diagram of another electronic device 10 provided in the embodiments of this application.

[0439] like Figure 29 As shown, the frame 11 may include a second position 202 located on the second side 132 and a third position 203 located on the first side 131, as well as a second grounding point 242. The frame 11 has gaps at the second position 202 and the third position 203. The frame 11 is coupled to the floor 300 at the second grounding point 242.

[0440] Antenna 200 may include a first radiator 211, a first feed circuit 221, a first tuning circuit 251, and a second tuning circuit 252. The first radiator 211 is the conductive portion of the frame between the second position 202 and the third position 203. The first end (the end closer to the second position 202) and the second end (the end closer to the third position 203) of the first radiator 211 are open ends.

[0441] The first radiator 211 includes a first feed point. The distance between the first feed point and the second position 201 is different from the distance between the first feed point and the third position 203, so that the first radiator 211 can simultaneously generate both line CM mode and line DM mode. The first feed circuit 221 is coupled to the first feed point and is used to feed an electrical signal to excite the antenna 200 to resonate. The difference in distance between the first feed point and the second position 202 and the distance between the first feed point and the third position 203 can also be understood as the difference in length between the first radiator 211 and the first end and the length between the first feed point and the second end.

[0442] The first radiator 211 also includes a first connection point 2111 and a second connection point 2112. The first connection point 2111 is located between the second position 202 and the second ground point 242. The second connection point 2112 is located between the third position 203 and the second ground point 242. The first tuning circuit 251 is coupled to the first connection point 2111, and the second tuning circuit 252 is coupled to the second connection point 2112.

[0443] In one embodiment, the first tuning circuit 251 and the second tuning circuit 252 are in a first circuit state, and the first radiator 211 is used to generate a first main resonance, the resonant frequency band of which includes a first frequency band. In another embodiment, the first tuning circuit 251 and the second tuning circuit 252 are in a first circuit state, and the first radiator 211 is used to generate a first resonance and a second resonance, the resonant frequency of the first resonance being lower than the resonant frequency of the second resonance, and the second resonance being the first main resonance.

[0444] In one embodiment, the first tuning circuit 251 and the second tuning circuit 252 are in a second circuit state, and the first radiator 211 is used to generate a second main resonance, the resonant frequency band of which includes the second frequency band. In another embodiment, the first tuning circuit 251 and the second tuning circuit 252 are in a second circuit state, and the first radiator 211 is used to generate a third resonance and a fourth resonance, the resonant frequency of the third resonance being lower than the resonant frequency of the fourth resonance, and the fourth resonance being the second main resonance.

[0445] It should be understood that, according to the technical solution provided in the embodiments of this application, the line CM mode and line DM mode of the first radiator 211 can be excited simultaneously. In the first circuit state, the first resonance is mainly generated by the line CM mode, and the second resonance is mainly generated by the line DM mode. In the second circuit state, the third resonance is mainly generated by the line CM mode, and the fourth resonance is mainly generated by the line DM mode.

[0446] Compared to when the entire first radiator 211 is positioned on the second side 132, when the second portion of the first radiator 211 is positioned on the second side 132, the radiation efficiency and system efficiency of the antenna 200 resonating in the line DM mode decrease slightly, but still exhibit good performance. Since antenna gain is related to antenna directivity and efficiency (radiation efficiency and system efficiency), increasing antenna efficiency (radiation efficiency and system efficiency) while maintaining directivity can also increase antenna gain.

[0447] In one embodiment, the frequency difference between the resonant point of the second resonance and the resonant point of the first resonance is less than or equal to 300 MHz. In another embodiment, the frequency difference between the resonant point of the second resonance and the resonant point of the first resonance is greater than or equal to 100 MHz.

[0448] In one embodiment, the frequency difference between the resonant point of the fourth resonance and the resonant point of the third resonance is less than or equal to 300 MHz. In another embodiment, the frequency difference between the resonant point of the fourth resonance and the resonant point of the third resonance is greater than or equal to 100 MHz.

[0449] In one embodiment, the length of the first portion of the first radiator 211 on the first side 131 is greater than or equal to one-half the length of the second portion of the first radiator 211 on the second side 132, and less than or equal to three-half the length of the second portion of the first radiator 211 on the second side 132.

[0450] It should be understood that, Figure 29 In the antenna 200 shown, the connection region between the first and second portions of the first radiator 211 is zigzag-shaped. Therefore, in this case, the length of the first portion can be understood as the length of the conductor between the third position 203 and the connection region, and the length of the second portion can be understood as the length between the second position 202 and the connection region. In one embodiment, the connection region between the first and second portions of the first radiator 211 is arc-shaped. Therefore, in this case, the length of the first portion can be understood as its length extending in the extension direction of the first side 131, and the length of the second portion can be understood as its length extending in the extension direction of the second side 132.

[0451] When the first radiator 211 is bent, and the length of the first part on the first side 131 and the length of the second part on the second side 132 are within the above range, the resonance generated by the line DM mode has good radiation efficiency and system efficiency.

[0452] Figure 29 The only difference between the antenna 300 shown and the antenna 200 shown in the above embodiment is the position of the main radiator (the radiator that feeds in electrical signals) when performing satellite communication.

[0454] The same frame 11 can be understood as having gaps at the first position 201, second position 202, third position 203, and fourth position 204, and being coupled to the floor 300 at the first grounding point 241, second grounding point 242, and third grounding point 243. The same frame 11 can also be understood as having the same length ratio between the first position 201, second position 202, third position 203, and fourth position 204. The same frame 11 can also be understood as having a width at the first grounding point 241, second grounding point 242, and third grounding point 243 where the frame is connected to the grounding element.

[0455] Furthermore, in Figure 29 In the illustrated electronic device 10, the third position 203 is located on the first side 131 of the frame 11, and the second position 202 is located on the second side. The first radiator 211 is bent, for example, L-shaped.

[0456] In one embodiment, the length of the first radiator 211 between the first connection point 2111 and the first end is less than or equal to half the length of the first radiator 211 between the second grounding point 242 and the first end. In another embodiment, the distance between the first connection point 2111 and the second position 202 on the first radiator 211 is less than or equal to half the distance between the second grounding point 242 and the second position 202 on the first radiator 211.

[0457] In one embodiment, the length D1 of the border between the first connection point 2111 and the second position 202 and the length L1 of the border between the third position 203 and the second position 202 satisfy: D1 ≤ L1 × 30%. In one embodiment, D1 ≤ L1 × 10%. In one embodiment, D1 is less than or equal to 8 mm.

[0458] In one embodiment, the length of the first radiator 211 between the second connection point 2112 and the second end is less than or equal to half the length of the first radiator 211 between the second grounding point 242 and the second end. In another embodiment, the distance between the second connection point 2112 and the third position 203 on the first radiator 211 is less than or equal to half the distance between the second grounding point 242 and the third position 203 on the first radiator 211.

In one embodiment, D2 ≤ L1 × 10%. In one embodiment, D2 is less than or equal to 8 mm.

[0460] In one embodiment, in Figure 29 The antenna 200 shown includes a second radiator 212 and a third radiator 213. The second radiator 212 is the conductive portion of the frame between the second position 202 and the first ground point 241, and the third radiator 213 is the conductive portion of the frame between the second ground point 242 and the first position 201.

[0461] In one embodiment, the antenna 200 includes a fourth radiator 214 and a fifth radiator 215, which can be coupled with... Figure 26 The structure shown in 200 is the same.

[0462] It should be understood that, Figure 29 In the illustrated embodiment, the conductive portion of the frame between the second position 202 and the third position 203 is used as an example to illustrate the first radiator 211.
