Technical Field

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

[0003] Currently, existing terminal electronic devices use frame antennas as radiators. For example, in satellite navigation or satellite communication systems, frame radiators are primarily used to form linearly polarized antennas. When performing satellite navigation or satellite communication, users need to align the antenna's maximum radiation direction with the satellite to establish a communication connection with the satellite. However, the maximum radiation direction of the linearly polarized antenna formed by the frame radiator is perpendicular to the electronic device's display screen. Therefore, users need to point the screen toward the sky when performing satellite navigation or communication, which is extremely inconvenient.

[0092] When used in this application, "within the range of...", unless it is specifically stated that the end value is not included, it is assumed that both end values ​​of the range are included. For example, in the range of 1 to 5, the two values ​​1 and 5 are included.

[0093] Coupling: can be understood as direct coupling and / or indirect coupling, and "coupling connection" can be understood as direct coupling connection and / or indirect coupling connection. Direct coupling can also be referred to as "electrical connection", which is understood as the physical contact and electrical conduction between components; it can also be understood as the form in which different components in the circuit structure are connected through physical lines such as printed circuit board (PCB) copper foil or wires that can transmit electrical signals; "indirect coupling" can be understood as two conductors being electrically conductive in an airless / non-contact manner. In one embodiment, indirect coupling can also be referred to as capacitive coupling, for example, signal transmission is achieved by forming an equivalent capacitance through coupling between the gap between two conductive parts.

[0094] Component / device: includes at least one of lumped component / device and distributed component / device.

[0095] Lumped component / device: This refers to all components whose size is much smaller than the wavelength relative to the circuit's operating frequency. For a signal, the component's characteristics remain constant at all times, regardless of frequency.

[0096] Distributed components / devices: Unlike lumped components, if the size of the component is similar to or larger than the wavelength relative to the circuit operating frequency, then when the signal passes through the component, the characteristics of each point of the component itself will vary due to changes in the signal. At this time, the component as a whole cannot be regarded as a single entity with fixed characteristics, but should be called a distributed component.

[0097] Capacitance: This can be understood as lumped capacitance and / or distributed capacitance. Lumped capacitance refers to capacitive components, such as capacitors; distributed capacitance (or distributed capacitance) refers to the equivalent capacitance formed by two conductive parts separated by a certain gap.

[0098] Inductance: This can be understood as lumped inductance and / or distributed inductance. Lumped inductance refers to inductive components, such as inductors; distributed inductance (or distributed inductance) refers to the equivalent inductance formed by a certain length of conductive material.

[0099] Radiator: A device in an antenna used to receive / send electromagnetic wave radiation. In some cases, the narrow meaning of "antenna" is the radiator, which converts the guided wave energy from the transmitter into radio waves, or converts radio waves into guided wave energy, used to radiate and receive radio waves. The modulated high-frequency current energy (or guided wave energy) generated by the transmitter is transmitted to the transmitting radiator via the feeder line, where it is converted into a certain polarized electromagnetic wave energy and radiated in the desired direction. The receiving radiator converts the electromagnetic wave energy of a certain polarization from a specific direction in space into modulated high-frequency current energy and transmits it to the receiver input via the feeder line.

[0100] The radiator may include a conductor with a specific shape and size, such as a linear or sheet shape, etc., and the present application does not limit the specific shape. In one embodiment, the linear radiator can be simply referred to as a linear antenna. In one embodiment, the linear radiator can be implemented by a conductive frame, and can also be called a frame antenna. In one embodiment, the linear radiator can be implemented by a bracket conductor, and can also be called a bracket antenna. In one embodiment, the wire diameter (for example, including thickness and width) of the linear radiator, or the radiator of the linear antenna is much smaller than the wavelength (for example, the wavelength of the medium) (for example, less than 1 / 16 of the wavelength), and the length can be comparable to the wavelength (for example, the wavelength of the medium) (for example, the length is about 1 / 8 of the wavelength, or 1 / 8 to 1 / 4, or 1 / 4 to 1 / 2, or longer). The main forms of linear antennas include dipole antennas, half-wave oscillator antennas, monopole antennas, loop antennas, and inverted F antennas (also known as IFA, Inverted F Antenna). For example, for a dipole antenna, each dipole antenna typically includes two radiating branches, and each branch is fed by a feeding portion from the feeding end of the radiating branch. For example, an IFA can be regarded as a monopole antenna with a ground path added. The IFA has a feeding point and a grounding point, and because its side view is an inverted F shape, it is called an inverted F antenna. 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 by a planar conductor (such as a conductive sheet or a 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 a silver paste. The shape of the sheet radiator includes circular, rectangular, annular, etc., and the present application does not limit the specific shape. The structure of a microstrip antenna generally consists of a dielectric substrate, a radiator, and a floor, wherein the dielectric substrate is arranged between the radiator and the floor.

[0101] The radiator may also include a slot or slot formed in a conductor, for example, a closed or semi-closed slot or slot formed in a grounded conductor surface. In one embodiment, a slotted or slotted radiator may be referred to as a slot antenna or slot antenna. In one embodiment, the radial dimension (e.g., including the width) of the slot or slot of the slot antenna / slot antenna is much smaller than the wavelength (e.g., the dielectric wavelength) (e.g., less than 1 / 16 of the wavelength), and the length dimension may be comparable to the wavelength (e.g., the dielectric wavelength) (e.g., the length is approximately 1 / 8 of the wavelength, or 1 / 8 to 1 / 4, or 1 / 4 to 1 / 2, or longer). In one embodiment, a radiator with a closed slot or slot may be referred to as a closed slot antenna. In one embodiment, a radiator with a semi-closed slot or slot (e.g., a closed slot or slot with an additional opening) may be referred to as an open slot antenna. In some embodiments, the slot is elongated. In some embodiments, the slot is approximately half a wavelength (e.g., the dielectric wavelength). In some embodiments, the slot is approximately an integer multiple of the wavelength (e.g., one wavelength). In some embodiments, the slot can be fed with a transmission line spanning one or both sides, thereby exciting a radio frequency electromagnetic field in the slot and radiating electromagnetic waves into space. In one embodiment, the radiator of a slot antenna or slot antenna can be implemented as a conductive frame with both ends grounded, also known as a frame antenna. In this embodiment, the slot antenna or slot antenna can be considered to include a linear radiator spaced from the floor and grounded at both ends, thereby forming a closed or semi-enclosed slot or slot. In one embodiment, the radiator of a slot antenna or slot antenna can be implemented as a bracket conductor with both ends grounded, also known as a bracket antenna.

[0102] The feed circuit is a combination of all circuits used for receiving and transmitting radio frequency signals. The feed circuit may include a transceiver and an RF front end circuit. In some cases, the "feed circuit" is understood in a narrow sense as a radio frequency chip (RFIC, Radio Frequency Integrated Circuit), and the RFIC can be considered to include an RF front end chip and a transceiver. The feed circuit has the function of converting radio waves (e.g., radio frequency signals) and electrical signals (e.g., digital signals). Generally, it is considered to be part of the radio frequency.

[0103] In some embodiments, the electronic device may also include a test socket (or RF socket or RF test socket). This test socket can be used to insert a coaxial cable and test the characteristics of the RF front-end circuit or antenna radiator through the cable. The RF front-end circuit can be considered as the circuit portion coupled between the test socket and the transceiver.

[0104] In some embodiments, the RF front-end circuit may be integrated into a RF front-end chip in the electronic device, or the RF front-end circuit and the transceiver may be integrated into a RF chip in the electronic device.

[0105] It should be understood that any two of the first / second / ...Nth feeding circuits in the present application can share the same transceiver, for example, transmitting signals through a radio frequency channel in a transceiver (for example, a port (pin) of a radio frequency chip); they can also share a radio frequency front-end circuit, for example, processing signals through a tuning circuit or amplifier in a radio frequency front-end.

[0106] It should also be understood that two feeding circuits in the first / second / ...Nth feeding circuit in the present application usually correspond to two radio frequency test sockets in the electronic device.

[0107] A matching circuit is a circuit used to adjust the radiation characteristics of an antenna. In one embodiment, the matching circuit is coupled between the feed circuit and the corresponding radiator. In another embodiment, the matching circuit is coupled between the test socket and the radiator. Typically, the matching circuit is a combination of circuits coupled between the radiator and the ground plane. In one embodiment, the matching circuit may include a tuning circuit and / or electronic components, and the tuning circuit may be an electronic component used to switch the coupling connection of the radiator. The matching circuit performs impedance matching and / or frequency tuning functions. Generally, it is considered to be part of the antenna.

[0108] The grounding structure / feeding structure may include a connector, such as a metal spring, through which the radiator is coupled to the floor / feeding structure is coupled to the feeding circuit. In some embodiments, the feeding structure may include a transmission line / feeding line, and the grounding structure may include a grounding wire.

[0109] End / point: The "end / point" in the first end / second end / feeding end / grounding end / feeding point / grounding point / connection point of an antenna radiator should not be narrowly understood as an end point or end portion that is physically disconnected from other radiators. It can also be considered as a point or section on a continuous radiator. In one embodiment, an "end / point" may include a connection / coupling area on an antenna radiator that is coupled to other conductive structures. For example, a feeding end / feeding point may be a coupling area on an antenna radiator that is coupled to a feeding structure or feeding circuit (for example, an area facing a portion of the feeding circuit). For another example, a grounding end / grounding point may be a connection / coupling area on an antenna radiator that is coupled to a grounding structure or grounding circuit.

[0110] Open end, closed end: In some embodiments, the open end and the closed end are, for example, relative to whether they are grounded. The closed end is grounded, and the open end is not grounded. In some embodiments, the open end and the closed end are, for example, relative to other conductors. The closed end is electrically connected to other conductors, and the open end is not electrically connected to other conductors. In one embodiment, the open end can also be referred to as a floating end, a free end, an open end, or an open-circuit end. In one embodiment, the closed end can also be referred to as a grounded end or a short-circuit end. It should be understood that in some embodiments, other conductors can be coupled through the open end to transfer coupling energy (which can be understood as transferring current).

[0111] In some embodiments, the "closed end" can also be understood from the perspective of current distribution. The closed end or the grounded end can be understood as a point with larger current on the radiator, or as a point with smaller electric field on the radiator. In one embodiment, the current distribution characteristics of larger current / smaller electric field can be maintained by coupling electronic devices (for example, capacitors, inductors, etc.) through the closed end. In one embodiment, the current distribution characteristics of larger current / smaller electric field can be maintained by opening a gap at or near the closed end (for example, a gap filled with insulating material).

[0112] In some embodiments, the understanding of "open end" can also be viewed from the perspective of current distribution. The open end or floating end can be understood as a point with low current on the radiator, or as a point with high electric field on the radiator. In one embodiment, coupling electronic devices (for example, capacitors, inductors, etc.) through the open end can maintain the current distribution characteristics of the low current point / high electric field point.

[0113] It should be understood that coupling the radiator end at a gap (from the perspective of the radiator structure, it is similar to the radiator at the opening of the open end or the suspended end) with electronic devices (for example, capacitors, inductors, etc.) can make the radiator end a point with larger current / smaller electric field. In this case, it should be understood that the radiator end at the gap is actually a closed end or a grounded end, etc.

[0114] The “suspended radiator” mentioned in the embodiments of the present application means that the radiator is not directly connected to the feeder line / feeder branch and / or the grounding line / grounding branch, but is fed and / or grounded through indirect coupling.

[0115] It should be understood that the "suspended" in "suspended end" and "suspended radiator" does not mean that there is no structure around the radiator to support it. In one embodiment, the suspended radiator can be, for example, a radiator disposed on the inner surface of the insulating back cover.

[0116] The current same direction / reverse direction mentioned in the embodiments of the present application should be understood as the direction of the main current on the conductor on the same side is the same direction / reverse direction. For example, when stimulating a unidirectional distributed current on a conductor that is bent or ring-shaped (for example, the current path is also bent or ring-shaped), it should be understood that, for example, the main currents stimulated on the conductors on both sides of the ring conductor (for example, a conductor surrounding a gap, on the conductors on both sides of the gap) are opposite in direction, which still falls within the definition of the unidirectional distributed current in the embodiments of the present application. In one embodiment, the current same direction on a conductor can refer to the current on the conductor having no reversal point. In one embodiment, the current reverse on a conductor can refer to the current on the conductor having at least one reversal point. In one embodiment, the current same direction on two conductors can refer to the current on both conductors having no reversal point and flowing in the same direction. In one embodiment, the current reverse on two conductors can refer to the current on both conductors having no reversal point and flowing in opposite directions. The current same direction / reversal on multiple conductors can be understood accordingly.

[0117] The electric field in the embodiments of the present application is in the same direction or opposite direction, which should be understood as the direction of the main electric field generated by the conductor in the space (for example, the electric field between the conductor and the floor) being in the same direction or opposite direction. For example, when a unidirectional distributed electric field is excited on a curved or ring-shaped conductor (for example, the gap formed between the floor and the conductor is also curved or ring-shaped), it should be understood that, for example, the direction of the electric field in the gap is from the floor to the conductor, or from the conductor to the floor. Although the main electric fields excited in the gaps on both sides of the ring-shaped conductor (for example, the gaps on both sides of the gap of the conductor surrounding a gap) are opposite in direction, they still fall within the definition of unidirectional distributed electric fields in the embodiments of the present application. In one embodiment, the electric field in the same direction between a conductor and the floor can mean that there is no reversal point between the electric field between the conductor and the floor. In one embodiment, the electric field in the opposite direction between a conductor and the floor can mean that there is at least one reversal point between the electric field between the conductor and the floor. In one embodiment, the electric field in the same direction between two conductors and the floor can mean that there is no reversal point between the electric field between the two conductors and the floor, and the electric fields between the two conductors and the floor radiate in the same direction (for example, the positive direction of the z-axis). In one embodiment, the electric fields between two conductors and the floor are in opposite directions, which means that the electric fields between the two conductors and the floor have no reverse points and flow in opposite directions. The electric fields between multiple conductors and the floor can be understood to be in the same or opposite directions accordingly.

[0118] Resonance / resonance frequency: The resonant frequency is also called the resonance frequency. The resonant frequency can have a frequency range, that is, the frequency range in which resonance occurs. The frequency corresponding to the strongest resonance point is the center frequency point frequency. The return loss characteristic of the center frequency can be less than -20dB. It should be understood that, unless otherwise specified, the antenna / radiator mentioned in this application produces a "first / second... resonance", where the first resonance should be the fundamental mode resonance generated by the antenna / radiator, or in other words, the lowest frequency resonance generated by the antenna / radiator. It should be understood that the antenna / radiator can generate one or more antenna modes according to the specific design, and each antenna mode can generate a corresponding fundamental mode resonance.

[0119] Resonant frequency band: The range of the resonant frequency is the resonant frequency band. The return loss characteristic of any frequency point in the resonant frequency band can be less than -6dB or -5dB.

[0120] Communication frequency band / operating frequency band: Regardless of the type of antenna, it always operates within a certain frequency range (bandwidth). For example, an antenna that supports the B40 frequency band operates between 2300MHz and 2400MHz, or in other words, the antenna's operating frequency band includes the B40 frequency band. The frequency range that meets the required specifications can be considered the antenna's operating frequency band.

[0121] The resonant frequency band and the operating frequency band may be the same, or may partially overlap. In one embodiment, one or more resonant frequency bands of the antenna may overlap one or more operating frequency bands of the antenna.

[0122] Electrical length: It can refer to the ratio of physical length (i.e. mechanical length or geometric length) to the wavelength of the transmitted electromagnetic wave. The electrical length can satisfy the following formula:

[0123] Where L is the physical length and λ is the wavelength of the electromagnetic wave.

[0124] Wavelength: Or operating wavelength, this can be the wavelength corresponding to the center frequency of the resonant frequency or the center frequency of the operating frequency band supported by the antenna. For example, if the center frequency of the B1 uplink frequency band (resonant frequency 1920MHz to 1980MHz) is 1955MHz, the operating wavelength can be the wavelength calculated using 1955MHz. "Operating wavelength" is not limited to the center frequency; it can also refer to the wavelength corresponding to a non-center frequency of the resonant frequency or operating frequency band.

[0125] It should be understood that the wavelength of the radiation signal in air can be calculated as follows: (wavelength in air, or wavelength in vacuum) = speed of light / frequency, where frequency is the frequency of the radiation signal (MHz), and the speed of light can be taken as 3×10 8 m / s. The wavelength of the radiation signal in the medium can be calculated as follows: Wherein, ε is the relative dielectric constant of the medium. The wavelength in the embodiments of the present application generally refers to the dielectric wavelength, which can be the dielectric wavelength corresponding to the center frequency of the resonant frequency, or the dielectric wavelength corresponding to the center frequency of the working frequency band supported by the antenna. For example, assuming that the center frequency of the B1 uplink frequency band (resonant frequency is 1920MHz to 1980MHz) is 1955MHz, the wavelength can be the dielectric wavelength calculated using the frequency of 1955MHz. Not limited to the center frequency, "dielectric wavelength" can also refer to the dielectric wavelength corresponding to the non-center frequency of the resonant frequency or the working frequency band. For ease of understanding, the dielectric wavelength mentioned in the embodiments of the present application can be simply calculated by the relative dielectric constant of the medium filled on one or more sides of the radiator.

[0126] Antenna system efficiency (total efficiency): refers to the ratio of input power to output power at the antenna port.

[0127] Antenna radiation efficiency refers to the ratio of the power radiated by an antenna into space (i.e., the power effectively converted into electromagnetic waves) to the active power input to the antenna. Active power input to the antenna = antenna input power minus power loss; power loss primarily includes return loss and metal ohmic loss and / or dielectric loss. Radiation efficiency measures the antenna's radiation capability, and both metal loss and dielectric loss contribute to it.

[0128] Those skilled in the art will understand that efficiency is generally expressed as a percentage, which has a corresponding conversion relationship with dB. The closer the efficiency is to 0 dB, the better the efficiency of the antenna.

[0129] Antenna pattern: Also known as radiation pattern. It is a graph showing how the relative field strength (normalized modulus) of the antenna's radiation field changes with direction at a certain distance from the antenna (far field). It is usually represented by two mutually perpendicular plane patterns passing through the antenna's direction of maximum radiation.

[0130] Antenna patterns typically have multiple radiation beams. The beam with the strongest radiation intensity is called the main lobe, while the remaining beams are called side lobes. Among the side lobes, those in the opposite direction of the main lobe are also called back lobes.

[0131] Directivity: Also known as the directivity of an antenna, it refers to the ratio of the maximum power density to the average power density in the antenna pattern at a certain distance from the antenna (far field). It is a dimensionless ratio greater than or equal to 1. It can be used to indicate the energy radiation characteristics of an antenna. A larger directivity indicates that the antenna radiates more energy in a certain direction and the energy radiation is more concentrated.

[0132] Antenna Gain: This is used to measure how well an antenna radiates input power. Generally, the narrower the main lobe of an antenna pattern and the smaller the side lobes, the higher the antenna gain.

[0133] Polarization direction of an antenna: At a given point in space, the electric field strength E (vector) is a function of time t. As time passes, the endpoints of the vector periodically trace a trajectory in space. If this trajectory is straight and perpendicular to the ground, it is called vertical polarization. If it is horizontal to the ground, it is called horizontal polarization. If this trajectory is elliptical or circular and rotates clockwise or to the right as viewed along the propagation direction, it is called right-hand circular polarization (RHCP). If it rotates counterclockwise or to the left as viewed along the propagation direction, it is called left-hand circular polarization (LHCP).

[0134] Antenna axial ratio (AR): Under circular polarization, the electric field vector endpoints periodically trace out an ellipse in space. The ratio of the major axis to the minor axis of the ellipse is called the axial ratio. Axial ratio is a key performance indicator for circularly polarized antennas. It represents the purity of circular polarization and is a key indicator of the signal gain differences across the entire device in different directions. The closer the antenna's axial ratio is to 1 (the more the electric field vector endpoints periodically trace out a circular path in space), the better its circular polarization performance.

[0135] Antenna return loss: This can be understood as the ratio of the signal power reflected back to the antenna port by the antenna circuit to the antenna port's transmitted power. The smaller the reflected signal, the larger the signal radiated from the antenna into space, and the greater the antenna's radiation efficiency. The larger the reflected signal, the smaller the signal radiated from the antenna into space, and the lower the antenna's radiation efficiency.

[0136] Antenna return loss can be expressed using the S11 parameter, a type of S parameter. S11 represents the reflection coefficient and characterizes the antenna's transmission efficiency. The S11 parameter is typically negative. A smaller S11 parameter indicates lower antenna return loss and less energy reflected back from the antenna itself, meaning more energy actually enters the antenna and higher system efficiency. A larger S11 parameter indicates greater antenna return loss and lower system efficiency.

[0137] It should be noted that in engineering, an S11 value of -6dB is generally used as a standard. When the S11 value of an antenna is less than -6dB, it can be considered that the antenna can work normally, or the antenna can be considered to have good transmission efficiency.

[0138] Specific absorption rate (SAR): A measure of the amount of radio frequency radiation energy actually absorbed by the body. It's expressed in watts per kilogram (W / kg) or milliwatts per gram (mW / g). The precise definition of SAR is: the time derivative of the energy (dw) absorbed per unit mass (dm) per unit volume (dv) at a given mass density (ρ—tissue density).

[0139] There are currently two internationally accepted standards, one is the European standard 2w / kg, and the other is the American standard 1.6w / kg. According to the European standard, its specific meaning is that the electromagnetic radiation energy absorbed by each kilogram of human tissue shall not exceed 2 watts based on a 6-minute timeframe.

[0140] Ground (GND): can generally refer to at least a part of any grounding layer, grounding plate, or grounding metal layer in an electronic device (such as a mobile phone), or at least a part of any combination of any of the above grounding layers, grounding plates, or grounding components, etc. "Ground" can be used for grounding components in an electronic device. In one embodiment, "ground" can be the grounding layer of a circuit board of an electronic device, or it can be the grounding plate formed by the middle frame of the electronic device, or the grounding metal layer formed by the metal film under the screen. In one embodiment, the circuit board can be a printed circuit board (PCB), such as an 8-layer, 10-layer, or 12 to 14-layer board having 8, 10, 12, 13, or 14 layers of conductive material, or an element separated and electrically insulated by a dielectric layer or insulating layer such as fiberglass, polymer, etc. In one embodiment, the circuit board includes a dielectric substrate, a grounding layer, and a routing layer, and the routing layer and the grounding layer are electrically connected through vias. In one embodiment, components such as a display, touch screen, input buttons, transmitter, processor, memory, battery, charging circuit, and system-on-chip (SoC) structures can be mounted on or connected to a circuit board, or electrically connected to a trace layer and / or ground layer in the circuit board. For example, a radio frequency source can be located on a trace layer.

[0141] Any of the above-mentioned grounding layers, grounding plates, or grounding metal layers are made of a conductive material. In one embodiment, the conductive material can be any of the following: copper, aluminum, stainless steel, brass, and alloys thereof, copper foil on an insulating substrate, aluminum foil on an insulating substrate, gold foil on an insulating substrate, silver-plated copper, silver-plated copper foil on an insulating substrate, silver foil and tin-plated copper on an insulating substrate, cloth impregnated with graphite powder, a graphite-coated substrate, a copper-plated substrate, a brass-plated substrate, and an aluminum-plated substrate. Those skilled in the art will appreciate that the grounding layer / grounding plate / grounding metal layer can also be made of other conductive materials.

[0142] Grounding refers to coupling to the ground / floor in any manner. In one embodiment, grounding can be achieved through physical grounding, such as physical grounding at a specific location on the frame using a portion of the midframe's structural components (or referred to as a physical ground). In one embodiment, grounding can be achieved through device grounding, such as through a series or parallel connection of a capacitor, inductor, or resistor (or referred to as a device ground).

[0143] The technical solutions of the embodiments of the present application will be described below with reference to the accompanying drawings.

[0144] As shown in FIG1 , 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, cover 13 may be a glass cover or may be replaced with a cover made of other materials, such as a PET (Polyethylene terephthalate) material.

[0145] The cover plate 13 may be disposed closely against the display module 15 , and may be mainly used to protect the display module 15 and prevent dust.

[0146] In one embodiment, the display module 15 may include a liquid crystal display panel (LCD), a light emitting diode (LED) display panel, or an organic light-emitting diode (OLED) display panel, etc., which is not limited in the embodiment of the present application.

[0147] The middle frame 19 mainly supports the entire device. FIG1 shows that the PCB 17 is arranged between the middle frame 19 and the back cover 21. It should be understood that in one embodiment, the PCB 17 can also be arranged between the middle frame 19 and the display module 15. This embodiment of the present application does not limit this. The printed circuit board PCB 17 can be made of a flame-resistant material (FR-4) dielectric board, a Rogers dielectric board, a mixed dielectric board of Rogers and FR-4, and so on. Here, FR-4 is a code for a grade of flame-resistant material, and the Rogers dielectric board is a high-frequency board. Electronic components, such as radio frequency chips, are carried on the PCB 17. In one embodiment, a metal layer can be provided on the printed circuit board PCB 17. The metal layer can be used to ground the electronic components carried on the printed circuit board PCB 17, and can also be used to ground other components, such as bracket antennas, frame antennas, etc. The metal layer can be called a floor, a grounding plate, or a grounding layer. In one embodiment, the metal layer can be formed by etching metal on the surface of any layer of the dielectric board in the PCB 17. In one embodiment, the metal layer used for grounding can be provided 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 the edge of its ground layer. In one embodiment, the metal middle frame 19 can also be used to ground the aforementioned components. The electronic device 10 may also have other floor / grounding plates / grounding layers, as previously described and will not be further described here.

[0148] The electronic device 10 may further include a battery (not shown). 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, and this is not limited in this embodiment of the present application. In some embodiments, the PCB 17 is divided into a main board and a sub-board, and the battery may be disposed between the main board and the sub-board. The main board may be disposed between the middle frame 19 and the upper edge of the battery, and the sub-board may be disposed between the middle frame 19 and the lower edge of the battery.

[0149] The electronic device 10 may further include a frame 11, which may be formed of a conductive material such as metal. The frame 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 frame 11 may have four sides surrounding the display module 15 to help secure the display module 15.

[0150] In one implementation, the frame 11 made of a conductive material can directly serve as the conductive frame of the electronic device 10, for example, forming a metallic frame appearance, suitable for a metallic industrial design (ID). In another implementation, the outer surface of the frame 11 can be made of a conductive material, such as a metal material, thereby forming a metallic frame appearance. In these implementations, the conductive portion of the frame 11 can serve as an antenna radiator for the electronic device 10.

[0151] In another implementation, the outer surface of the frame 11 can also be a non-conductive material, such as plastic, to form the appearance of a non-metallic frame, which is suitable for non-metallic ID. In one implementation, the inner surface of the frame 11 may include a conductive material, such as a metal 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 provided on the inner surface of the frame 11 (or the conductive material on the inner surface) is arranged in contact with the non-conductive material of the frame 11 to facilitate antenna radiation, and both the conductive material and the non-conductive material should be regarded as part of the frame 11.

[0152] The middle frame 19 may include a border 11, and the middle frame 19 including the border 11 is an integral part that can support the electronic devices in the whole machine. The cover 13 and the back cover 21 are respectively covered along the upper and lower edges of the border to form a shell or housing (housing) of the electronic device. In one embodiment, the cover 13, the back cover 21, the border 11 and / or the middle frame 19 can be collectively referred to as the shell or housing of the electronic device 10. It should be understood that "shell or housing" can be used to refer to part or all of any one of the cover 13, the back cover 21, the border 11 or the middle frame 19, or to part or all of any combination of the cover 13, the back cover 21, the border 11 or the middle frame 19.

[0153] The frame 11 on the middle frame 19 can at least partially serve as an antenna radiator to transmit and receive radio frequency signals. A gap can exist between this portion of the frame serving as the radiator and the rest of the middle frame 19 to ensure a good radiation environment for the antenna radiator. In one embodiment, the middle frame 19 can be provided with an aperture in this portion of the frame serving as the radiator to facilitate antenna radiation.

[0154] Alternatively, the frame 11 may not be considered as part of the middle frame 19. In one embodiment, the frame 11 may be connected to the middle frame 19 and formed as one piece. In another embodiment, the frame 11 may include a protrusion extending inward to be connected to the middle frame 19, for example, by means of a shrapnel, a screw, welding, etc. The protrusion of the frame 11 can also be used to receive a feed signal, so that at least a portion of the frame 11 serves as a radiator of the antenna to receive / transmit radio frequency signals. There may be a gap 42 between this portion of the frame that serves as the radiator and the middle frame 30, thereby ensuring that the antenna radiator has a good radiation environment, so that the antenna has a good signal transmission function.

[0155] The back cover 21 can be made of metal, non-conductive materials such as glass or plastic, or a combination of conductive and non-conductive materials. In one embodiment, the conductive back cover 21 can replace the middle frame 19 and integrate with the frame 11 to support the electronic components within the device.

[0156] In one embodiment, the middle frame 19 and / or the conductive parts in the back 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 middle frame.

[0157] The antenna of the electronic device 10 can also be set in the frame 11. When the frame 11 of the electronic device 10 is a non-conductive material, the antenna radiator can be located in the electronic device 10 and arranged along the frame 11. For example, the antenna radiator is set close to the frame 11 to minimize the volume occupied by the antenna radiator and be closer to the outside of the electronic device 10 to achieve better signal transmission effect. It should be noted that the antenna radiator is set close to the frame 11 means that the antenna radiator can be set close to the frame 11, or it can be set close to the frame 11, for example, there can be a certain small gap between the antenna radiator and the frame 11.

[0158] The antenna of electronic device 10 may also be disposed within the housing, such as a bracket antenna or millimeter-wave antenna (not shown in FIG1 ). The clearance for the antenna disposed within the housing can be provided by a slot / opening in any of the middle frame, and / or the frame, and / or the back cover, and / or the display screen, or by a non-conductive gap / aperture formed between any of these. The antenna clearance ensures the antenna's radiation characteristics. It should be understood that the antenna clearance can be a non-conductive area formed by any conductive component within electronic device 10, through which the antenna radiates signals to the outside world. In one embodiment, antenna 40 may be an antenna based on a flexible printed circuit (FPC), an antenna based on laser-direct-structuring (LDS), or a microstrip disk antenna (MDA). In one embodiment, the antenna may also be a transparent structure embedded within the screen of electronic device 10, making the antenna a transparent antenna embedded within the screen of electronic device 10.

[0159] FIG. 1 only schematically illustrates some components of the electronic device 10 , and the actual shapes, sizes, and structures of these components are not limited by FIG. 1 .

[0160] It should be understood that in the embodiments of the present application, the surface where the display screen of the electronic device is located can be considered as the front surface, the surface where the back cover is located can be considered as the back surface, and the surface where the frame is located can be considered as the side surface.

[0161] It should be understood that in the embodiments of the present application, when a user holds an electronic device (usually vertically and facing the screen), the electronic device is located at a position having a top, a bottom, a left side, and a right side. It should be understood that in the embodiments of the present application, when a user holds an electronic device (usually vertically and facing the screen), the electronic device is located at a position having a top, a bottom, a left side, and a right side.

[0162] An embodiment of the present application provides an electronic device, which includes an antenna. The antenna uses a conductive part of the frame of the electronic device as a main radiator and / or a parasitic branch, which can enhance the user experience when performing satellite navigation or communication.

[0163] First, Figures 2 and 3 will introduce the two antenna modes involved in this application. Figure 2 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 is a schematic diagram of the differential-mode structure of another antenna provided in this application and the corresponding current and electric field distribution. The antenna radiators in Figures 2 and 3 are open at both ends, and their common-mode mode and differential-mode modes can be referred to as line common-mode mode and line differential-mode mode, respectively.

[0164] It should be understood that the “common-differential mode” or “CM-DM mode” in this application refers to a line common mode mode and a line differential mode mode generated on the same radiator.

[0165] 1. Wire common mode (CM) mode

[0166] (a) in Figure 2 shows that the radiator of the antenna 40 is open at both ends and is connected to a feeding circuit (not shown) at the middle position 41. In one embodiment, the feeding form of the antenna 40 adopts symmetrical feed. The feeding circuit can be connected to the middle position 41 of the antenna 40 through a feeding line 42. It should be understood that symmetrical feeding can be understood as one end of the feeding circuit being connected to the radiator and the other end being coupled to the floor for grounding, wherein the connection point between the feeding circuit and the radiator (feeding point) is located at the center of the radiator. The center of the radiator can be, for example, the midpoint of the geometric structure, or the midpoint of the electrical length (or an area within a certain range near the above midpoint).

[0167] 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. For example, the connection between the feed line 42 and the antenna 40 covers the middle position 41 .

[0168] (b) in FIG2 shows the current and electric field distribution of the antenna 40. As shown in (b) in FIG2, the current is distributed in opposite directions on both sides of the middle position 41, for example, symmetrically; the electric field is distributed in the same direction on both sides of the middle position 41. As shown in (b) in FIG2, the current at the feed line 42 is distributed in the same direction. Based on the same direction distribution of the current at the feed line 42, the feeding shown in (a) in FIG2 can be called line CM feeding. Based on the opposite distribution of the current on both sides of the connection between the radiator and the feed line 42, the antenna mode shown in (b) in FIG2 can be called a line CM mode (also referred to as a CM mode for short, for example, for a linear antenna, the CM mode refers to a line CM mode). The current and electric field shown in (b) in FIG2 can be respectively referred to as the current and electric field of the line CM mode.

[0169] The current is stronger at the center 41 of the antenna 40 (the highest current point is near the center 41 of the antenna 40) and weaker at both ends of the antenna 40, as shown in FIG2(b). The electric field is weaker at the center 41 of the antenna 40 and stronger at both ends of the antenna 40.

[0170] 2. Line differential mode (DM) mode

[0171] As shown in Figure 3(a), the left and right ends of the two radiators of antenna 50 are open, and a feed circuit is connected at a center position 51. In one embodiment, antenna 50 uses an anti-symmetrical feed. One end of the feed circuit is connected to one of the radiators via a feed line 52, and the other end of the feed circuit is connected to the other radiator via a feed line 52. Center position 51 can be the geometric center of antenna 50 or the gap formed between the radiators.

[0172] It should be understood that the "center-antisymmetric feeding" mentioned in this application can be understood as the positive and negative poles of the feed unit being connected to two connection points near the aforementioned midpoint of the radiator. In one embodiment, the signals output by the positive and negative poles of the feed unit have the same amplitude but opposite phases, for example, a phase difference of 180°±10°.

[0173] Figure 3(b) shows the current and electric field distribution of antenna 50. As shown in Figure 3(b), the current is distributed in the same direction on both sides of the center position 51 of antenna 50, for example, in an antisymmetric distribution; the electric field is distributed in opposite directions on both sides of the center position 51. As shown in Figure 3(b), the current at the feed line 52 is distributed in opposite directions. Based on the opposite current distribution at the feed line 52, the feeding shown in Figure 3(a) can be referred to as linear DM feeding. Based on the current being distributed in the same direction on both sides of the connection between the radiator and the feed line 52, the antenna mode shown in Figure 3(b) can be referred to as a linear DM mode (or simply a DM mode, for example, for a linear antenna, a DM mode refers to a linear DM mode). The current and electric field shown in Figure 3(b) can be referred to as the current and electric field of the linear DM mode, respectively. It should be understood that based on the current being distributed in the same direction on both sides of the connection between the radiator and the feed line 52, the antenna mode shown in Figure 3(b) can also be referred to as a half-antenna mode, a half-wavelength mode, or simply a half-mode.

[0174] In one embodiment, in the wire DM mode, or half mode, the current is stronger at the center 51 of the antenna 50 (the highest current point is near the center 51 of the antenna 50) and weaker at both ends of the antenna 50, as shown in FIG3(b). The electric field is weaker at the center 51 of the antenna 50 and stronger at both ends of the wire antenna 50.

[0175] It should be understood that the antenna radiator can be understood as a metal structural member that generates radiation, and the number of the radiator can be one, as shown in FIG2 , or two, as shown in FIG3 , which can be adjusted according to actual design or production needs. For example, for the line CM mode, two radiators can be used as shown in FIG3 , with the two ends of the two radiators arranged opposite to each other and separated by a gap. A symmetrical feeding method is adopted at the two ends close to each other, for example, the same feed source signal is fed into the two ends of the two radiators close to each other, and an effect similar to the antenna structure shown in FIG2 can also be obtained. Correspondingly, for the line DM mode, one radiator can be used as shown in FIG2 , with two feeding points set in the middle of the radiator and an antisymmetric feeding method is adopted. For example, if two symmetrical feeding points on the radiator are fed with signals with the same amplitude and opposite phases, an effect similar to the antenna structure shown in FIG3 can also be obtained.

[0176] 3. Line CM-DM mode

[0177] FIG2 and FIG3 above respectively show that when both ends of the radiator are open, a line CM mode and a line DM mode are generated by adopting different feeding methods.

[0178] When the antenna uses asymmetric feeding (the feeding point is offset from the center of the radiator, including side feeding or offset feeding), or the radiator's grounding point (where it couples with the floor) is asymmetric (the grounding point is offset from the center of the radiator), the antenna can simultaneously produce a first resonance and a second resonance, corresponding to the linear CM mode and the linear DM mode, respectively. For example, the first resonance corresponds to the linear CM mode, with the current and electric field distributions shown in Figure 2(b). The second resonance corresponds to the linear DM mode, with the current and electric field distributions shown in Figure 3(b).

[0179] FIG4 is a schematic diagram of another electronic device 10 provided in an embodiment of the present application.

[0180] As shown in FIG. 4 , the conductive frame 11 of the electronic device 10 may include a first side 131 and a second side 132 intersecting at an angle, and the length of the first side 131 is greater than the length of the second side 132 .

[0181] The second side 132 may have a first position 101 and a second position 102, and the frame 11 may have gaps at 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.

[0182] In one embodiment, the first frame 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, the first frame 105 can be considered symmetrical along the virtual axis of the second side 132 when the ratio of the distances between 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%.

[0183] It should be understood that, for an antenna, as the structure of the antenna becomes more symmetrical (for example, the radiator 105 is located at the center of the second side 132 ), the radiation characteristics of the antenna are improved (for example, bandwidth, radiation efficiency, etc.).

[0184] Figures 5 and 6 are simulation results of the antenna 100 in the electronic device 10 shown in Figure 4. Figure 5 shows the S-parameter simulation results of the antenna 100 in the electronic device 10 shown in Figure 4. Figure 6 shows the system efficiency and radiation efficiency simulation results of the antenna 100 in the electronic device 10 shown in Figure 4.

[0185] As shown in Figure 5, when the antenna shown in Figure 4 is fed using the feeding methods shown in Figures 2 and 3, it can generate a linear CM mode and a linear DM mode, respectively. In both the linear CM and linear DM modes, the antenna can resonate near the target frequency band (e.g., 2 GHz).

[0186] It should be understood that for the sake of simplicity of discussion, in this embodiment, only the line CM mode and the line DM mode are excited separately as an example. Referring to the above embodiment, the line CM mode and the line DM mode can also be excited simultaneously by asymmetric feeding (the feeding point deviates from the middle position of the radiator, including side feeding or offset feeding), and / or the grounding point of the radiator (the coupling point with the floor) is asymmetric (the grounding point deviates from the middle position of the radiator).

[0187] As shown in Figure 6, 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 resonance point (2GHz), the radiation efficiency of the CM mode is -4.42dB, the system efficiency is -4.47dB, and the radiation efficiency in the DM mode is -1.27dB, and the system efficiency is -1.39dB.

[0188] It should be understood that when the first frame is located at the center of the second side, the transverse mode can be excited (accounting for more than the longitudinal mode), but the currents corresponding to the transverse mode will cancel each other out. Therefore, the system efficiency and radiation efficiency of the CM mode are low.

[0189] As for the DM mode, in the DM mode, the radiation of the antenna is mainly generated by the radiator (first frame). When it is set at the center of the second side, the system efficiency and radiation efficiency are better than those in the CM mode.

[0190] FIG7 is a schematic diagram of an electronic device 10 provided in an embodiment of the present application.

[0191] As shown in FIG. 7 , the electronic device 10 includes a frame 11 , an antenna 200 , and a floor 300 .

[0192] The frame 11 may include a first side 131 and a second side 132 intersecting at an angle, and the length of the first side 131 is greater than the length of the second side 132 .

[0193] It should be understood that the technical solutions provided in the embodiments of the present application can also be applied to foldable electronic devices. For the sake of simplicity, only an electronic device including a single display screen (non-foldable) is used as an example for description. In a foldable electronic device, the first side 131 and the second side 132 can be understood as the first side and the second side corresponding to the foldable electronic device when it is in a folded state.

[0194] The second side 132 may have a first position 201 and a second position 202, and a first grounding member located between the first position 201 and the second position 202. The frame 11 may have a first gap and a second gap, respectively, at the first position 201 and the second position 202. The frame 11 may be coupled to the floor 300 via the first grounding member.

[0195] In one embodiment, the width of the gaps provided 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. The gaps provided in the embodiments of the present application may be 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 frame on both sides of the gap.

[0196] The antenna 200 includes a first radiator 211 , a first feeding circuit 221 , a first tuning circuit 251 , and a second tuning circuit 252 .

[0197] The first radiator 211 is a conductive portion of the frame at the first position 201 and the second position 202. The first end (the end close to the first position 201) and the second end (the end close to the second position 202) of the first radiator 211 are open ends.

[0198] The first radiator 211 includes a first feeding point 231. The distance between the first feeding point 231 and the first position 201 is different from the distance between the first feeding point 231 and the second position 202, so that the first radiator 211 generates both a line CM mode and a line DM mode. The first feeding circuit 221 is coupled to the first feeding 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 feeding point 231 and the first position 201 and the distance between the first feeding 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 feeding point 231 and the first end and the length between the first feeding point and the second end. It should be understood that in this application, the "distance" from the first point / first end / first position on the radiator / frame to the second point / second end / second position can be understood as the same or similar.

[0199] It should be understood that the difference in distance between the first feeding point 231 and the first position 201 and the second position 202 can be understood as the absolute value of the difference between the first distance between the first feeding circuit 221 and the first position 201 and the second distance between the first feeding point 231 and the second position 202 being greater than or equal to 5 mm. At the same time, for the sake of simplicity, the embodiments of the present application only illustrate the electrical connection between the first feeding circuit 221 and the first feeding point 231. In actual applications, indirect coupling connection can also be used, and the embodiments of the present application do not limit this. Moreover, in the embodiments of the present application, coupling connection can be understood accordingly.

[0200] 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.

[0201] It should be understood that the first tuning circuit 251 and the second tuning circuit 252 can be used to adjust the resonance point frequency generated by the first radiator 211, so that the antenna 200 operates in different operating frequency bands.

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

[0203] In one embodiment, the first tuning circuit 251 and the second tuning circuit 252 are in the second circuit state, and the first radiator 211 is used to generate a second main resonance, where the resonant frequency band of the second main resonance includes the second frequency band. In one embodiment, the first tuning circuit 251 and the second tuning circuit 252 are in the second circuit state, and the first radiator 211 is used to generate a third resonance and a fourth resonance, where the resonant point frequency of the third resonance is lower than the resonant point frequency of the fourth resonance, and the fourth resonance is the second main resonance.

[0204] It should be understood that according to the technical solutions provided in the embodiments of the present application, offset feeding (different distances between the first feeding point 231 and the first position 201 and the second position 202) can simultaneously excite the line CM mode and the line DM mode of the first radiator 211. In the first circuit state, the first resonance is primarily generated by the line CM mode, and the second resonance is primarily generated by the line DM mode. In the second circuit state, the third resonance is primarily generated by the line CM mode, and the fourth resonance is primarily generated by the line DM mode.

[0205] As can be seen from the above embodiment, when the first radiator 211 is arranged on the second side 132, the radiation efficiency and system efficiency of the resonance generated by the linear DM mode of the antenna 200 are high. Since the gain of the antenna is related to the directivity and efficiency (radiation efficiency and system efficiency) of the antenna, when the efficiency (radiation efficiency and system efficiency) of the antenna is improved, the directivity remains unchanged and the gain of the antenna can also be improved. Therefore, although the polarization characteristic of the radiation generated by the antenna 200 when the electronic device 10 communicates in the first frequency band or the second frequency band is linear polarization, there will be a 3dB loss when receiving circularly polarized electromagnetic waves, but because the antenna 200 has good efficiency (radiation efficiency and system efficiency), it also has good directivity.

[0206] In one embodiment, the first grounding member can be located in the central region of the first radiator 211. The central region includes the center of the first radiator 211, and the length of the first radiator 211 on both sides of the center is 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 member is located in the central region of the first radiator 211, which can be understood as the center of the first grounding member being located within the central region of the first radiator 211.

[0207] It should be understood that when the first radiator 211 generates the first main resonance or the second main resonance, it may correspond to a line DM mode. In the line DM mode, the central region includes a high current point, and the placement of the first grounding member near the high current point does not affect the first main resonance or the second main resonance.

[0208] In one embodiment, first tuning circuit 251 and second tuning circuit 252 include circuits that include switches. The switches can be used to switch between electronic components with different resistance, capacitance, or inductance values ​​coupled to the connection point in different circuit states. Alternatively, the switches can be in an open state, disconnecting the electronic components from the connection point. Alternatively, the switches can directly couple floorboard 300 to the connection point, without any electronic components interposed between them.

[0209] In one embodiment, the first tuning circuit 251 and the second tuning circuit 252 do not include switches and may be circuits formed by cascading multiple electronic components. The first tuning circuit 251 and the second tuning circuit 252 may have different equivalent capacitance values ​​or equivalent inductance values ​​at different frequencies.

[0210] In one embodiment, the first frequency band and the second frequency band may correspond to the transmit frequency band and the receive frequency band in satellite communications, respectively. For example, in the Tiantong satellite system, the first frequency band may include 1980 MHz-2010 MHz, and the second frequency band may include 2170 MHz-2200 MHz. In the Beidou satellite system, the first frequency band may include 1610 MHz-1626.5 MHz, and the second frequency band may include 2483.5 MHz-2500 MHz. Alternatively, the present invention may also be applied to other satellite communication systems, and the embodiments of the present application are not limited thereto.

[0211] In one embodiment, when the antenna 200 operates in the Tiantong satellite system (the operating frequency band of the antenna 200 includes at least part of the frequency band in the Tiantong satellite system), the electronic device 10 can perform voice communication through the antenna 200. In one embodiment, when the antenna 200 operates in the Beidou satellite system (the operating frequency band of the antenna 200 includes at least part of the frequency band in the Beidou satellite system), the electronic device 10 can send or receive short messages through the antenna 200.

[0212] It should be understood that, for the sake of simplicity of discussion, the satellite communication performed by the electronic device 10 described in the embodiments of the present application can be understood as the electronic device 10 can use the antenna 200 to send or receive short messages to or from the satellite, or the electronic device 10 can use the antenna 200 to perform voice communication via the satellite.

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

[0214] In one embodiment, the frequency difference between the resonance point of the fourth resonance and the resonance point of the third resonance is less than or equal to 300 MHz. In one embodiment, the frequency difference between the resonance point of the fourth resonance and the resonance point of the third resonance is greater than or equal to 100 MHz.

[0215] It should be understood that the first radiator 211 resonates in both the linear CM mode and the linear DM mode. When the frequency difference between the resonance point of the second resonance (fourth resonance) and the resonance point of the first resonance (third resonance) is greater than or equal to 100 MHz and less than or equal to 300 MHz, the proportion of the linear DM mode in the second resonance (fourth resonance) can be increased, so that the antenna 200 radiates primarily in 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 resonance point of the second resonance (fourth resonance) and the resonance point of the first resonance (third resonance) is greater than 300 MHz, the proportion of other operating modes (e.g., the linear CM mode) in the second resonance (fourth resonance) increases, resulting in a decrease in the radiation efficiency and system efficiency of the antenna 200 in the first frequency band (second frequency band).

[0216] In one embodiment, the frequency difference between the resonance point of the second resonance and the resonance point of the first resonance, and / or the frequency difference between the resonance point of the fourth resonance and the resonance point of the third resonance can be determined based on the width of the connection between the first grounding piece and the frame 11 and the center frequency of the operating frequency band of the antenna 200.

[0217] In one embodiment, the center frequency of the working frequency band of the antenna 200 is greater than or equal to 1 GHz and less than 2.5 GHz. For example, the working frequency band includes at least part of the frequency band in the Tiantong satellite system and at least part of the frequency band in the Beidou satellite system.

[0218] When the width of the connection between the first grounding member and the frame 11 is greater than or equal to 2 mm and less than 4 mm, the frequency difference between the resonance point of the second resonance and the resonance point of the first resonance is less than or equal to 450 MHz, and / or the frequency difference between the resonance point of the fourth resonance and the resonance point of the third resonance is less than or equal to 450 MHz. The frequency difference between the resonance point of the second resonance and the resonance point of the first resonance is greater than or equal to 50 MHz, and / or the frequency difference between the resonance point of the fourth resonance and the resonance point of the third resonance is greater than or equal to 50 MHz.

[0219] When the width of the connection between the first grounding member 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 resonance point of the second resonance and the resonance point of the first resonance is less than or equal to 400 MHz, and / or the frequency difference between the resonance point of the fourth resonance and the resonance point of the third resonance is less than or equal to 400 MHz. The frequency difference between the resonance point of the second resonance and the resonance point of the first resonance is greater than or equal to 50 MHz, and / or the frequency difference between the resonance point of the fourth resonance and the resonance point of the third resonance is greater than or equal to 50 MHz.

[0220] 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 part of the frequency bands in other systems.

[0221] When the width of the connection between the first grounding member and the frame 11 is greater than or equal to 2 mm and less than 4 mm, the frequency difference between the resonance point of the second resonance and the resonance point of the first resonance is less than or equal to 450 MHz, and / or the frequency difference between the resonance point of the fourth resonance and the resonance point of the third resonance is less than or equal to 450 MHz. The frequency difference between the resonance point of the second resonance and the resonance point of the first resonance is greater than or equal to 100 MHz, and / or the frequency difference between the resonance point of the fourth resonance and the resonance point of the third resonance is greater than or equal to 100 MHz.

[0222] When the width of the connection between the first grounding member 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 resonance point of the second resonance and the resonance point of the first resonance is less than or equal to 400 MHz, and / or the frequency difference between the resonance point of the fourth resonance and the resonance point of the third resonance is less than or equal to 400 MHz. The frequency difference between the resonance point of the second resonance and the resonance point of the first resonance is greater than or equal to 100 MHz, and / or the frequency difference between the resonance point of the fourth resonance and the resonance point of the third resonance is greater than or equal to 100 MHz.

[0223] In one embodiment, the first feeding circuit may include a first RF channel and a second RF channel, wherein the first RF channel (for feeding an electrical signal in a first frequency band) is used to generate a first resonance and a second resonance, and the second RF channel (for feeding an electrical signal in a second frequency band) is used to generate a third resonance and a fourth resonance. The first RF channel may be used to feed a first electrical signal, which may correspond to a transmitting frequency band in satellite communications. The second RF channel may be used to feed a second electrical signal, which may correspond to a receiving frequency band in satellite communications. The first RF channel and the second RF channel may be understood as two different circuits for transmitting electrical signals, for example, as two different RF channels in a radio frequency chip (RFIC).

[0224] It should be understood that the feeding circuits provided in the embodiments of the present application may all have the above-mentioned structure, and feeding the electrical signal in a combined feeding manner can reduce the feeding points on the radiator and reduce the complexity of the system design.

[0225] 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 element and the first end.

[0226] 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 element and the first position 201 on the first radiator 211 .

[0227] In one embodiment, the grounding member has a certain width and is connected to the radiator along the width. In one embodiment, the length of the radiator between the grounding member and the first end, or the distance between the grounding member 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 member, that is, the distance / length to the nearest edge of the grounding member.

[0228] In one embodiment, the location where the radiator connects to the grounding element can be considered a grounding point on the radiator. For simplicity, the following description uses the location where the grounding element connects to the radiator (e.g., an edge) 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 in accordance with the above.

[0229] 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 first position 201 and the second position 202 satisfy the following: D1 ≤ L1 × 30%. In one embodiment, D1 ≤ L1 × 10%, as shown in FIG8 . In one embodiment, D1 is less than or equal to 8 mm.

[0230] It should be understood that in the embodiments of the present 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 via 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.

[0231] 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 ground point 241 and the second end. In one 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 ground point 241 and the second position 202 on the first radiator 211.

[0232] 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 first position 201 and the second position 202 satisfy the following: D2 ≤ L1 × 30%. In one embodiment, D2 ≤ L1 × 10%, as shown in FIG8 . In one embodiment, D2 is less than or equal to 8 mm.

[0233] It should be understood that the first connection point 2111 and the second connection point 2112 can be set in the area close to the first gap and the second gap. The first end and the second end of the first radiator 211 are open ends. The area near the open end generally has a strong electric field, and the area with a strong electric field has better tuning performance.

[0234] In one embodiment, first position 201 and second position 202 are symmetrical along a virtual axis of second side 132, and the lengths of the second sides on either side of the virtual axis are the same. Due to certain errors in engineering applications, first position 201 and second position 202 can be considered symmetrical along the virtual axis of second side 132 when the ratio of the virtual axis to the distance between first position 201 and second position 202 is greater than or equal to 90% and less than or equal to 110%.

[0235] It should be understood that as the symmetry of the first radiator 211 increases, the radiation characteristics of the antenna 200 are improved (eg, bandwidth, radiation efficiency, etc.).

[0236] In one embodiment, the first feeding point 231 may coincide with the first connection point 2111 or the second connection point 2112 .

[0237] It should be understood that in the embodiments of the present application, the feeding circuit can be coupled to the feeding point via a feeding element (e.g., a metal spring). When the feeding point and the connection point coincide, both the tuning circuit and the feeding circuit can be coupled to the radiator (feeding point / connection point) via the feeding element, thereby reducing the number of connection locations on the radiator and facilitating engineering implementation.

[0238] FIG9A is a schematic diagram of an electronic device 10 provided in an embodiment of the present application.

[0239] As shown in FIG. 9A , the electronic device 10 may include a conductive frame 11 , an antenna 200 and a first feeding circuit 221 .

[0240] 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 located between the second position 202 and the third position 203.

[0241] Antenna 210 includes a first radiator 211, a second radiator 212, and a third radiator 213. First radiator 211 includes at least a portion of the frame between first position 201 and second position 202, second radiator 212 includes at least a portion of the frame between second position 202 and first ground point 241, and third radiator 213 includes at least a portion of the frame between first ground point 241 and third position 203.

[0242] It should be understood that in some actual production or design, the radiator may also include metal parts arranged around the frame. For the sake of simplicity of discussion, in the embodiments of this application, only the part of the frame is used as the radiator as an example, and no limitation is imposed on this.

[0243] 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. The slits formed in the embodiment of the present application can all be 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.

[0244] The frame 11 is grounded at a first grounding point 241. The first end (the end closest to the first position 201) and the second end (the end closest to the second position 202) of the first radiator 211 are open. The first end (the end closest to the second position 202) of the second radiator 212 is open, and the second end is grounded (the end closest to the first grounding point 241). The first end (the end closest to the first grounding point 241) of the third radiator 213 is grounded, and the second end is open (the end closest to the third position 203).

[0245] The first radiator 211 includes a first feeding point 231. The distance between the first feeding point 231 and the first position 201 is different from the distance between the first feeding point 231 and the second position 202. The first feeding circuit 221 is coupled to the first feeding point 231 and is configured to feed an electrical signal to stimulate the antenna 200 to resonate.

[0246] It should be understood that the difference in distance between the first feeding point 231 and the first position 201 and the second position 202 can be understood as the absolute value of the difference between the first distance between the first feeding circuit 221 and the first position 201 and the second distance between the first feeding point 231 and the second position 202 being greater than or equal to 5 mm. At the same time, for the sake of simplicity, the embodiment of the present application only uses the electrical connection between the first feeding circuit 221 and the first feeding point 231 as an example for explanation. In actual applications, an indirect coupling connection can also be used, and the embodiment of the present application does not limit this. Moreover, in the embodiment of the present application, the coupling connection can be understood accordingly.

[0247] In one embodiment, the frame 11 includes a first side 131 and a second side 132 intersecting 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 .

[0248] The first radiator 211 is used to generate a first resonance and a second resonance. The resonance point frequency of the first resonance is lower than the resonance point frequency of the second resonance. The resonance frequency range of the second resonance includes the first frequency range.

[0249] The third radiator 213 is used to generate a first parasitic resonance, and the resonance point frequency of the first parasitic resonance is lower than the resonance point frequency of the second resonance.

[0250] It should be understood that according to the technical solution provided in the embodiment of the present application, the CM mode and DM mode of the first radiator 211 can be simultaneously excited by side feeding (the distances between the first feeding point 231 and the first position 201 and the second position 202 are different), generating a first resonance (mainly generated by the CM mode) and a second resonance (mainly generated by the DM mode) respectively. It can be seen from the above embodiment that when the first radiator 211 is arranged on the second side 132, the radiation efficiency and system efficiency of the resonance generated by the DM mode of the antenna 200 are high. Since the directivity of the antenna is related to the gain and efficiency (radiation efficiency and system efficiency) of the antenna, when the efficiency (radiation efficiency and system efficiency) of the antenna is improved, the directivity of the antenna can also be improved. Therefore, although the polarization characteristic of the radiation generated by the antenna 200 when the electronic device 10 communicates in the first frequency band is linear polarization, and there will be a 3dB loss when receiving circularly polarized electromagnetic waves, because the antenna 200 has good efficiency (radiation efficiency and system efficiency), it also has good directivity.

[0251] At the same time, when the first radiator 211 generates the second resonance by the DM mode, the third radiator 213 can be stimulated to generate the first parasitic resonance. In one embodiment, when the first feeding circuit 221 feeds 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, and obtain an effect similar to a current array, thereby improving the directivity of the antenna 200. The directivity of the antenna 200 can be improved by the third radiator 213, and the energy radiated by the antenna 200 toward the top of the electronic device 10 (for example, in the y direction) is increased, so that when the user uses the electronic device 10 for satellite navigation or communication in the first frequency band, there is no need to change the posture of holding the electronic device 10, so as to obtain a good user experience.

[0252] In one embodiment, a frequency difference between a resonance point of the second resonance and a resonance point of the first resonance is greater than or equal to 100 MHz and less than or equal to 300 MHz.

[0253] It should be understood that the first radiator 211 can generate a first resonance (CM mode) and a second resonance (DM mode) by the CM mode and the DM mode, respectively. When the frequency difference between the resonance point of the second resonance and the resonance point of the first resonance is greater than or equal to 100 MHz and less than or equal to 300 MHz, the proportion of the DM mode in the second resonance can be increased, so that the antenna 200 mainly radiates by 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 resonance point of the second resonance and the resonance point of the first resonance is greater than 300 MHz, the proportion of other operating modes (e.g., CM mode) in the second resonance increases, resulting in a decrease in the radiation efficiency and system efficiency of the antenna 200 in the first frequency band.

[0254] In one embodiment, a frequency difference between a resonance point of the second resonance and a resonance point of the first parasitic resonance is greater than 0 MHz and less than or equal to 200 MHz.

[0255] It should be understood that when the frequency difference between the resonance point of the second resonance and the resonance point of the first parasitic resonance is greater than 0 MHz and less than or equal to 200 MHz, the first feeding circuit 221 feeds an electrical signal, and at the resonance point of the second resonance, the current generated on the third radiator 213 and the current on the first radiator 211 in the same direction account for a larger proportion, which can further improve the directivity of the antenna 200.

[0256] In one embodiment, the distance between the first radiator 211 and the third radiator 213 may be greater than and equal to two-tenths of the first wavelength and less than or equal to one-half of the first wavelength, where the first wavelength is a vacuum wavelength corresponding to the first frequency band.

[0257] Correspondingly, the first radiator 211 can operate in a 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.

[0258] It should be understood that when the distance between the first radiator 211 and the third radiator 213 is within the above range, the directivity of the antenna 200 is better improved. 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.

[0259] 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.

[0260] It should be understood that as the symmetry of the first radiator 211 increases, the radiation characteristics of the antenna 200 are better.

[0261] In one embodiment, the third position 203 may be located at the first side 131 .

[0262] It should be understood that the third position 203 can be located on the first side 131 or the second side 132, both of which 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 embodiment of the present application does not limit this.

[0263] In one embodiment, the second radiator 212 is configured to generate a second parasitic resonance, and a resonance point frequency of the second parasitic resonance is higher than a resonance point frequency of the second resonance.

[0264] It should be understood that the second radiation 212 can improve the radiation efficiency and system efficiency of the antenna 200 in the second resonant frequency band, so that the antenna 200 has better radiation characteristics in the first frequency band.

[0265] In one embodiment, a frequency difference between a resonance point of the second parasitic resonance and a resonance point of the second resonance is greater than or equal to 200 MHz and less than or equal to 500 MHz.

[0266] It should be understood that because the ends of the radiators on both sides of the second position 202 are open, when the first feeding circuit 221 feeds an electrical signal, the coupling between the first radiator 211 and the second radiator 212 is relatively strong. 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 point of the second parasitic resonance and the resonant point of the second resonance is greater than or equal to 200 MHz and less than or equal to 500 MHz, the radiation efficiency and system efficiency of the antenna 200 in the first frequency band are significantly improved.

[0267] 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 feeding point 231 (including the first position 201 and the first feeding point 231, and in the following embodiment, is located between A and B, both including A and B). It should be understood that in the embodiment of the present application, the feeding circuit can be coupled to the feeding point through a feeding element. When the feeding point coincides with the connection point, both the switch and the feeding circuit can be coupled to the radiator (feeding point / connection point) through the feeding element. The second connection point 2112 is located between the second position 202 and the first feeding point 231. The electronic device 10 also 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.

[0268] 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 the resonant frequency of the fourth resonance, and the resonant frequency of the third resonance is higher than the resonant frequency of the first resonance. The resonant frequency of the fourth resonance is higher than the resonant frequency of the second resonance, and the resonant frequency range of the fourth resonance includes the second frequency range.

[0269] 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 (first port, which can be understood as the switch being coupled to the radiator through this port) of the switch and the connection port. In one embodiment, the first switch state can be that the common port and the connection port are disconnected and not electrically connected. Alternatively, in one embodiment, the first switch state can be that the common port and the connection port are short-circuited and electrically connected. In one embodiment, the connection port can be directly grounded, or at least one electronic component can be electrically connected between the connection port and the floor. Alternatively, in one embodiment, the switch includes multiple common ports, and the first switch state can be that at least part of the multiple common ports are short-circuited and electrically connected to the multiple connection ports. The switch states in the above-mentioned embodiments can all be understood accordingly, and the embodiments of the present application are not limited to this, and can be adjusted according to actual production or design.

[0270] 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 embodiment of the present application, the switch may be a single-pole multiple-throw (SPXT) according to actual production or design selection, and the embodiment of the present application does not limit this. The switches in the embodiment of the present application can be understood accordingly, and it is only necessary to ensure that the number of connection ports of the switch is greater than or equal to the number of electronic components or RF channels to be connected.

[0271] It should be understood that when the switch includes multiple common ports, the switch in the embodiment of the present application can also be multi-pole multi-throw (x pole x throw, XPXT), or can also be composed of multiple single-pole single throw (single pole single throw, SPST) switches connected in parallel.

[0272] In one embodiment, the length D1 of the frame between the first connection point 2111 and the first position 201 and the length L1 of the frame between the first position 201 and the second position 202 satisfy the following conditions: D1 ≤ L1 × 30%. In one embodiment, D1 ≤ L1 × 10%. In one embodiment, D1 is less than or equal to 3 mm.

[0273] In one embodiment, the length D2 of the frame between the second connection point 2112 and the second position 202 and the length L1 of the frame between the first position 201 and the second position 202 satisfy the following: D2 ≤ L1 × 30%. In one embodiment, D2 ≤ L1 × 10%. In one embodiment, D2 is less than or equal to 3 mm.

[0274] It should be understood that when the first connection point 2111 is set in an area close to the first position 201 and the second connection point 2112 is set in an area close to the second position 202, the electric field in this area is strong, which facilitates adjustment of the resonance point frequency generated by the first radiator 211.

[0275] In one embodiment, the first frequency band includes at least a portion of a frequency band between 1980 MHz and 2010 MHz, and the second frequency band includes at least a portion of a frequency band between 2170 MHz and 2200 MHz.

[0276] It should be understood that the technical solutions provided in the embodiments of the present application can be applied to the Tiantong satellite system as well as the Beidou satellite system. For example, the first frequency band can include at least part of the L-band (1610 MHz to 1626.5 MHz), and the second frequency band can include at least part of the S-band (2483.5 MHz to 2500 MHz). Alternatively, the technical solutions provided in the embodiments of the present application can be applied to other satellite communication systems, and the embodiments of the present application are not limited thereto.

[0277] In one embodiment, the third radiator 213 may further include a third connection point 2131 . The electronic device 10 may further include a third switch 253 . A common port of the third switch 253 is coupled to the third connection point 2131 .

[0278] It should be understood that the third switch 253 can be used to adjust the resonance point frequency of the resonance generated by the third radiator 213 so that the resonance point frequency of the resonance generated by the third radiator 213 can be within the above-mentioned range with the resonance point frequency of the second resonance or the resonance point frequency of the fourth resonance generated by the first radiator 211, thereby improving the directivity of the antenna 200.

[0279] In one embodiment, the length D3 of the frame between the third connection point 2131 and the third position 203 and the length L2 of the frame between the first grounding point 241 and the third position 203 satisfy the following conditions: D3 ≤ L2 × 30%. In one embodiment, D3 ≤ L2 × 10%. In one embodiment, D3 is less than or equal to 3 mm.

[0280] In one embodiment, the second radiator 212 may further include a fourth connection point 2121 . The electronic device 10 may further include a fourth switch 254 . A common port of the fourth switch 254 is coupled to the fourth connection point 2121 .

[0281] It should be understood that the fourth switch 254 can be used to adjust the resonance point frequency of the resonance generated by the second radiator 212 so that the resonance point frequency of the resonance generated by the second radiator 212 can be within the above-mentioned range with the resonance point frequency of the second resonance or the resonance point frequency of 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.

[0282] In one embodiment, the length D4 of the frame between the third connection point 2131 and the second position 202 and the length L3 of the frame between the first grounding point 241 and the second position 202 satisfy the following conditions: D4 ≤ L3 × 30%. In one embodiment, D4 ≤ L3 × 10%. In one embodiment, D4 is less than or equal to 3 mm.

[0283] In one embodiment, since satellite communication and cellular communication are not performed simultaneously, when electronic device 10 is performing satellite communication, third radiator 213 can be used to improve the directivity of antenna 200, and second radiator 212 can be used to improve the system efficiency and radiation efficiency of antenna 200. When electronic device 10 is not performing satellite communication, first radiator 211, second radiator 212, or third radiator 213 can be reused as the radiator of the cellular communication antenna.

[0284] In one embodiment, the second radiator 212 may further include a second feeding point 232, as shown in FIG10 . The electronic device 10 may further include a second feeding circuit 222. The second feeding circuit 222 is coupled to the second feeding point 232. In one embodiment, the second feeding point 232 is located between the fourth connection point 2121 and the first ground point 241.

[0285] In one embodiment, the second feed point 232 and the fourth connection point 2121 overlap. This overlap can be understood as the second feed circuit 222 and the fourth switch 254 being coupled to the second radiator 212 via the same connection component. 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 first ground point 241.

[0286] It should be understood that the first radiator 211 and the first feeding circuit 221 can form a first antenna unit. The second radiator 212 and the second feeding circuit 222 can form a second antenna unit, which can operate in a quarter-wavelength mode. The third radiator 213 and the third feeding circuit 223 form a third antenna unit, which can operate in a quarter-wavelength mode.

[0287] In one embodiment, the third feeding point 233 coincides with the third connection point 2131 .

[0288] In one embodiment, the operating frequency band of the second antenna unit may include 2.4 GHz for WiFi, and / or at least part of the frequency band in sub 6G, such as the n77 frequency band. In one embodiment, the operating frequency band of the third antenna unit may include at least part of the frequency band in the middle band (MB) (1710 MHz-2170 MHz), and / or at least part of the frequency band in 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.

[0289] 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 unit, allowing the third antenna unit to operate in different communication frequency bands. For example, the third switch 253 can be in different switch states to electrically connect different electronic components between the third connection point 2131 and the floor. The fourth switch 254 can also be used to determine the resonant frequency of the resonance generated by the second antenna unit, allowing the second antenna unit to operate in different communication frequency bands. For example, the fourth switch 254 can be in different switch states to electrically connect different electronic components between the fourth connection point 2121 and the floor.

[0290] In one embodiment, antenna 200 may further include a fourth radiator 214. Frame 11 may further include a second grounding point 242. First position 201 is located between second grounding point 242 and first feed point 231, and frame 11 is grounded at second grounding point 242. Fourth radiator 214 includes at least a portion of the frame between first position 201 and second grounding point 242.

[0291] It should be understood that the fourth radiator 214 and the fourth feeding circuit 224 can form a fourth antenna unit, which can operate in a quarter-wavelength mode and can be used to expand the communication frequency band of the electronic device 10. In one embodiment, the operating frequency band of the fourth antenna unit may include at least part of the intermediate frequency (1710 MHz-2170 MHz) and / or at least part of the high frequency (2300 MHz-2690 MHz) and / or at least part of the sub-6G frequency band, for example, the n77 band.

[0292] In one embodiment, the fourth radiator 213 may further include a fifth connection point 2131 . The electronic device 10 may further include a fifth switch 255 . A common port of the fifth switch 255 is coupled to the fifth connection point 2131 .

[0293] 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 unit can operate in different communication frequency bands. For example, the fifth switch 255 can be in different switching states to electrically connect different electronic components between the fifth connection point 2141 and the floor.

[0294] Meanwhile, when the electronic device 10 is performing satellite communication, the fourth antenna unit is inoperative. 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 electrically connected to the ground directly or via 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.

[0295] In one embodiment, the frame 11 may further include a third grounding point 243, which is located between the first position 201 and the first feeding point 231. The frame 11 is grounded at the third grounding point 243. Please refer to the embodiment shown in FIG9B.

[0296] FIG9B is a schematic diagram of an electronic device 10 provided in an embodiment of the present application.

[0297] As shown in FIG. 9B , the electronic device 10 may include a conductive frame 11 , an antenna 200 and a first feeding circuit 221 .

[0298] The frame 11 further 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.

[0299] Antenna 200 includes a second radiator 212 and a third radiator 213. Second radiator 212 is a conductive portion of the frame between second position 202 and second ground point 242. Third radiator 213 is a conductive portion of the frame between second ground point 242 and third position 203.

[0300] The frame 11 has a third gap formed therein and is coupled to the floor 300 at a second grounding point 242 .

[0301] The second radiator 212 has an open first end (the end near the second position 202) and a grounded second end (the end near the second grounding point 242). The third radiator 213 has a grounded first end (the end near the second grounding point 242) and an open second end (the end near the third position 203).

[0302] The third radiator 213 is used to generate a first parasitic resonance, and the resonance point frequency of the first parasitic resonance is lower than the resonance point frequency of the first main resonance.

[0303] When the first radiator 211 generates the first main resonance by the DM mode, the third radiator 213 can be stimulated to generate the first parasitic resonance. In one embodiment, when the first feeding circuit 221 feeds an electrical signal, at the resonance point of the first main 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, and obtain an effect similar to a current array, thereby improving the directivity of the antenna 200. The directivity of the antenna 200 can be improved by the third radiator 213, and the energy radiated by the antenna 200 toward the top of the electronic device 10 (for example, in the y direction) is increased, so that when the user uses the electronic device 10 for satellite navigation or communication in the first frequency band, there is no need to change the posture of holding the electronic device 10, so as to obtain a good user experience.

[0304] In one embodiment, the third radiator 213 may further include a third connection point 2131 . The electronic device 10 may further include a third tuning circuit 253 . The third tuning circuit 253 is coupled to the third connection point 2131 .

[0305] It should be understood that the third tuning circuit 253 can be used to adjust the resonance point frequency of the resonance generated by the third radiator 213, so that the third radiator 213 generates a first parasitic resonance and a 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, and obtaining an effect similar to a current array, which can improve the directivity of the antenna 200.

[0306] 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 the following: L1×80%≤L2≤L1.

[0307] In one embodiment, the frequency difference between the resonance point of the first main resonance and the resonance point of the first parasitic resonance is less than or equal to 200 MHz. In one embodiment, the frequency difference between the resonance point of the fourth resonance and the resonance point of the second parasitic resonance is less than or equal to 200 MHz.

[0308] It should be understood that when the frequency difference between the resonance point of the first main resonance (or the second main resonance) and the resonance point of the first parasitic resonance (or the second parasitic resonance) is less than or equal to 200 MHz, the first feeding circuit 221 feeds an electrical signal, and at the resonance point of the first main resonance (or the second main resonance), the current generated on the third radiator 213 and the current on the first radiator 211 in the same direction account for a larger proportion, which can further improve the directivity of the antenna 200.

[0309] In one embodiment, the length D3 of the frame between the third connection point 2131 and the third position 203 and the length H1 of the frame between the second grounding point 242 and the third position 203 satisfy the following conditions: D3 ≤ H1 × 30%. In one embodiment, D3 ≤ H1 × 10%. In one embodiment, D3 is less than or equal to 3 mm.

[0310] In one embodiment, the distance between the first radiator 211 and the third radiator 213 can be greater than or equal to two-tenths of the first wavelength and less than or equal to one-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 the vacuum wavelength and the medium wavelength (conduction wavelength) have a certain corresponding relationship, it can be calculated based on the equivalent dielectric constant of the medium disposed around the radiator, and this is understood accordingly in the embodiments of the present application.

[0311] Correspondingly, the first radiator 211 can operate in a half-wavelength mode (corresponding to the 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 part 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 part of the frame between the first position 201 and the second position 202.

[0312] It should be understood that when the distance between the first radiator 211 and the third radiator 213 is within the above range, the directivity of the antenna 200 is better improved. 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.

[0313] In one embodiment, the third position 203 may be located at the first side 131 .

[0314] It should be understood that the third position 203 can be located on the first side 131 or the second side 132, both of which 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 embodiment of the present application does not limit this.

[0315] In one embodiment, the second radiator 212 is configured to generate a third parasitic resonance, and the resonance frequency of the third parasitic resonance is higher than the resonance frequency of the first main resonance.

[0316] It should be understood that the second radiation 212 can improve the radiation efficiency and system efficiency of the antenna 200 in the resonance frequency band of the first main resonance, so that the antenna 200 has better radiation characteristics in the first frequency band.

[0317] In one embodiment, the second radiator 212 may further include a fourth connection point 2121 . The electronic device 10 may further include a fourth tuning circuit 254 . The fourth tuning circuit 254 is coupled to the fourth connection point 2121 .

[0318] It should be understood that the fourth tuning circuit 254 can be used to adjust the resonance point 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 frequency band and the second frequency band.

[0319] In one embodiment, the frequency difference between the resonance point of the third parasitic resonance and the resonance point of the first main resonance is greater than or equal to 200 MHz and less than or equal to 500 MHz. In one embodiment, the frequency difference between the resonance point of the fourth parasitic resonance and the resonance point of the second main resonance is greater than or equal to 200 MHz and less than or equal to 500 MHz.

[0320] It should be understood that because the ends of the radiators on both sides of the second position 202 are open, when the first feeding circuit 221 feeds an electrical signal, the coupling between the first radiator 211 and the second radiator 212 is relatively strong. 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 200 MHz and less than or equal to 500 MHz, the radiation efficiency and system efficiency of the antenna 200 in the first frequency band (second frequency band) are significantly improved.

[0321] In one embodiment, the length D4 of the frame between the third connection point 2131 and the second position 202 and the length H2 of the frame between the second grounding point 242 and the second position 202 satisfy the following conditions: D4 ≤ H2 × 30%. In one embodiment, D4 ≤ H2 × 10%. In one embodiment, D4 is less than or equal to 3 mm.

[0322] In one embodiment, since satellite communication and cellular communication are not performed simultaneously, when electronic device 10 is performing satellite communication, third radiator 213 can be used to improve the directivity of antenna 200, and second radiator 212 can be used to improve the system efficiency and radiation efficiency of antenna 200. When electronic device 10 is not performing satellite communication, first radiator 211, second radiator 212, or third radiator 213 can be reused as the radiator of the cellular communication antenna.

[0323] In one embodiment, the second radiator 212 may further include a second feeding point 232, as shown in FIG10 . The electronic device 10 may further include a second feeding circuit 222. The second feeding circuit 222 is coupled to the second feeding point 232. In one embodiment, the second feeding point 232 is located between the fourth connection point 2121 and the second ground point 242.

[0324] In one embodiment, the length R2 of the second radiator 212 (the length of the frame between the second position 202 and the second ground point 242) and the length L1 of the frame between the first position 201 and the second position 202 (the first radiator 211) satisfy the following relationship: L1×35%≤R2≤L1×60%. In one embodiment, the second feeding point 232 and the fourth connection point 2121 coincide with each other. The "coincidence" can be understood as the coupling connection between the second feeding circuit 222 and the fourth tuning circuit 254 and the second radiator 212 via the same connection component.

[0325] In one embodiment, the third radiator 213 may further include a third feeding point 233. The electronic device 10 may further include a third feeding circuit 223. The third feeding circuit 223 is coupled to the third feeding point 233. In one embodiment, the third feeding point 233 is located between the third connection point 2131 and the second ground point 242.

[0326] In one embodiment, the length R3 of the third radiator 213 (the length of the frame between the third position 203 and the second ground 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%.

[0327] It should be understood that the first radiator 211 and the first feeding circuit 221 can form a first antenna. The second radiator 212 and the second feeding circuit 222 can form a second antenna. Because the first end of the second radiator 212 (the end near the second position 202) is open and the second end is grounded (the end near the second grounding point 242), the second antenna can operate in a quarter-wavelength mode (in a quarter-wavelength mode, the current and electric field on the radiator are in the same direction, with the current peak near the grounded end and the electric field peak near the open end). The third radiator 213 and the third feeding circuit 223 form a third antenna. Because the first end of the third radiator 213 (the end near the second grounding point 242) is grounded and the second end is open (the end near the third position 203), the third antenna can operate in a quarter-wavelength mode.

[0328] In one embodiment, the third feeding point 233 coincides with the third connection point 2131 .

[0329] In one embodiment, the operating frequency band of the second antenna may include 2.4 GHz for WiFi and / or at least part of the sub-6 GHz frequency band, such as the n77 frequency band. In one embodiment, the operating frequency band of the third antenna may include at least part of the middle band (MB) (1710 MHz-2170 MHz) and / or at least part 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.

[0330] 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, allowing the third antenna to 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 floor. The fourth tuning circuit 254 can also be used to determine the resonant frequency of the resonance generated by the second antenna, allowing the second antenna to 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 floor.

[0331] At the same time, when the electronic device performs satellite communication or not performs satellite communication, the second radiator 212 and the third radiator 213 both generate resonance. When the electronic device 10 performs satellite communication, the second antenna and the third antenna do not work as the main feed antenna (for example, the antenna is disconnected from the corresponding feed source, or the corresponding feed source of the antenna is turned off), and the second radiator 212 and the third radiator 213 generate parasitic resonance by indirect coupling with the first radiator 211, thereby improving the radiation characteristics of the antenna 200 (for example, the frequency difference between the resonance point of the parasitic resonance and the resonance point of the main resonance is within the above range). When the electronic device 10 does not perform satellite communication, the second antenna and the third antenna can work as the main feed antenna, and the second radiator 212 and the third radiator 213 can resonate by the electrical signals fed in respectively, and the resonance point frequency of the resonance is different from the resonance point frequency of the parasitic resonance.

[0332] In the embodiment of the present application, the electronic device 10 does not perform satellite communication, which can be understood as the connection between the antenna 200 and the corresponding feed source (e.g., a satellite communication chip or module) is disconnected, or the corresponding feed source of the antenna 200 (e.g., a satellite communication chip or module) is turned off. It should be understood that when the electronic device 10 does not perform satellite communication, the electronic device can perform cellular communication or data communication transmission via WiFi, etc.

[0333] In one embodiment, antenna 200 may further include a fourth radiator 214. Frame 11 may further include a third grounding point 243. First position 201 is located between third grounding point 243 and first grounding point 241. Frame 11 is coupled to floor 300 at third grounding point 243. Fourth radiator 214 is the conductive portion of the frame between first position 201 and third grounding point 243.

[0334] In one embodiment, the length R4 of the fourth radiator 214 (the length of the frame between the first position 201 and the third ground 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%.

[0335] It should be understood that the fourth radiator 214 and the fourth feeding circuit 224 can form a fourth antenna, which can operate in a quarter-wavelength mode and can be used to expand the communication frequency band of the electronic device 10. In one embodiment, the operating frequency band of the fourth antenna can include at least part of the intermediate frequency band (1710 MHz-2170 MHz) and / or at least part of the high frequency band ((2300 MHz-2690 MHz) and / or at least part of the sub6G frequency band, for example, the n77 band).

[0336] In one embodiment, the fourth radiator 214 may further include a fifth connection point 2141 . The electronic device 10 may further include a fifth tuning circuit 255 . The fifth tuning circuit 255 is coupled to the fifth connection point 2141 .

[0337] 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 floor.

[0338] Meanwhile, when the electronic device 10 is performing satellite communication, the fourth antenna is inoperative. 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 plane or electrically connected via a 0 ohm resistor. The fourth radiator 214 is directly coupled to the ground plane 300 at the fifth connection point 2141 to prevent the fourth radiator 214 from interfering with satellite communication.

[0339] When the electronic device 10 is performing satellite communication, the fourth antenna does not operate as a primary feed antenna, and the fourth radiator 214 may not generate an operating resonance, or may generate a parasitic operating resonance through indirect coupling. When the electronic device 10 is not performing satellite communication, the fourth antenna may operate as a primary feed antenna, and the fourth radiator 214 may resonate with the input electrical signal.

[0340] In one embodiment, the frame 11 may further include a third grounding point 243 , which is located between the first position 201 and the first feeding point 231 . The frame 11 is grounded at the third grounding point 243 .

[0341] It should be understood that the third grounding point 243 can be used to improve the isolation between the second antenna and the fourth antenna. Furthermore, when the fourth antenna is operating, the fourth radiator 214 serves as a main radiation branch (including the fourth feed point 234), and the frame between the fourth grounding point 244 and the first position 201 can serve as a parasitic branch of the fourth antenna, used to improve the radiation characteristics of the fourth antenna. 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 floor, so that the parasitic branch can generate resonances of different frequencies.

[0342] Correspondingly, the first antenna, with the border between the second location 202 and the first ground point 241 serving as the primary radiating branch, can operate in a 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, enabling the first antenna to operate in different communication frequency bands. For example, the second tuning circuit 252 can be in different tuning circuit states, allowing different electronic components to be electrically connected between the second connection point and the floor.

[0343] In one embodiment, the operating frequency band of the first antenna may include the L1 frequency band in GPS, and / or at least part of the frequency band in sub 6G, for example, the n79 frequency band.

[0344] In one embodiment, the L1 frequency band in GPS may include 1575.42 MHz ± 1.023 MHz. In one embodiment, sub 6G may include the n77 frequency band and the n79 frequency band. The n77 frequency band may include 3300 MHz to 4200 MHz. The n79 frequency band may include 4400 MHz to 5000 MHz.

[0345] It should be understood that when the first antenna operates in the L1 frequency band of GPS, since the L1 frequency band of GPS is incompatible with the frequency band of satellite communications (cannot be shared and matched), the electronic device 10 may further include a switch coupled between the first feed point 231 and the floor. When the electronic device 10 is performing satellite communications, the first antenna is not operating, and the switch is disconnected (or, the circuit between the first feed point 231 and the floor is equivalent to being open, for example, the equivalent inductance between the first feed point 231 and the floor is greater than 20nH). When the first antenna operates in the L1 frequency band of GPS, the switch is connected, and electronic components may be electrically connected between the second tuning circuit and the floor to match the L1 frequency band.

[0346] At the same time, when the electronic device performs satellite communication or not, the first radiator 211 generates resonance. When the electronic device 10 performs satellite communication, the first antenna does not work as a main feed antenna, and the entire branch 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 does not perform satellite communication, the first antenna can work as a main feed antenna, and some branches of the first radiator 211 (the frame between the second position 202 and the first grounding point 241) generate resonance, and the resonance point frequency of the resonance is different from the resonance point frequency of the first main resonance or the resonance point frequency of the second main resonance. For example, when the electronic device 10 does not perform satellite communication, the first antenna can work as a GPS antenna so that the electronic device can perform GPS positioning.

[0347] In one embodiment, at least one of the L1 and L5 frequency bands of GPS can be supported by any one of the second antenna, the third antenna, the fourth antenna, and the fifth and sixth antennas described below. For example, a signal of 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 can be radiated via the third feed circuit 223 and the third radiator 213. It should be understood that since the L1 frequency band in GPS includes 1575.42 MHz ± 1.023 MHz and the L5 frequency band in GPS includes 1176.45 MHz, which have a frequency difference with the satellite communication frequency band in the embodiments of the present application, the electronic device in the present application can also perform satellite communication and GPS satellite navigation simultaneously.

[0348] In one embodiment, grounding can be achieved through a first grounding member at the first grounding point 241. The width of the first grounding member 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.

[0349] It should be understood that the grounding point and / or connection point can be implemented by a metal spring or a rib structure connecting the metal spring to the middle plate of the middle frame. When a metal component such as a metal spring is used, 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 a rib structure connecting the metal spring to the middle plate of the middle frame is used, 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 rib structure.

[0350] In one embodiment, the electronic device includes the above-mentioned middle frame, and the middle frame includes the above-mentioned frame 11 and the middle plate. In one embodiment, the middle plate is electrically connected to the floor 300 through multiple locations. In one embodiment, the middle plate can be regarded as a part of the floor 300. In one embodiment, the frame 11 is electrically connected to the middle plate through a connecting rib structure (such as a first grounding member, not shown in the figure). The connecting rib structure (such as a first grounding member, not shown in the figure) is connected between the frame and the middle plate, and is integrally formed with the frame and the middle plate. For the sake of simplicity of discussion, the grounding members described in the embodiments of the present application can be understood accordingly.

[0351] In one embodiment, a length of the first grounding member extending between the frame and the floor is less than or equal to 6 mm.

[0352] In one embodiment, an electronic component is coupled between the first grounding member and the floor, and an equivalent capacitance value of the electronic component is greater than or equal to 3 pF.

[0353] It should be understood that when the electronic device 10 operates in a satellite frequency band, the electronic component is disconnected in at least a portion of the frequency band in the satellite system (at least a portion of the frequency band in the Tiantong satellite system and / or at least a portion of the frequency band in the Beidou satellite system), thereby substantially disconnecting the first grounding member from the floor. The "disconnected state" in this application refers to the current state between the first grounding member and the floor. For example, in the "disconnected state," the current distributed between the first radiator 211 and the floor does not substantially couple or flow through the first grounding member and the electronic component. It should be understood that "substantially no current couples or flows" is not an absolute term. In this embodiment, when the electronic device 10 operates in a satellite frequency band, the first radiator 211 can generate a linear DM mode through the configuration of the electronic component. This means that the electronic component is disconnected in at least a portion of the frequency band in the satellite system, and current substantially does not couple or flow through the first grounding member and the electronic component. In one embodiment, the resonance generated by the linear DM mode of the antenna 200 has high radiation efficiency and system efficiency.

[0354] When the electronic device 10 is not operating in the satellite frequency band, the electronic component is in a conductive state in the operating frequency band of the second antenna and / or the operating frequency band of the fourth antenna, which can cause the first grounding member and the floor to be roughly in a short-circuit state. The "short-circuit state" in this application refers to the current state between the first grounding member and the floor. For example, in the "short-circuit state", the first radiator 211 and the current distributed on the floor are generally coupled / flowed through the first grounding member and the electronic component. In one embodiment, the first radiator 211 is coupled to the floor through the first grounding member and the electronic component, which can achieve 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 respectively located on both sides of the first grounding member, and the two achieve better isolation through the current short-circuit state at the first grounding member.

[0355] The electronic component can also be used to adjust the electrical length of the radiator. In one embodiment, the electronic component 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 .

[0356] For the sake of brevity in the discussion, the structures of the grounding members in the application embodiments can be understood accordingly, and for the sake of brevity in the discussion, they will not be described one by one.

[0357] In one embodiment, an electronic switch is coupled in series between the first grounding piece and the floor, and the switch can be used to control the electrical connection state between the first grounding piece and the floor.

[0358] It should be understood that when electronic device 10 operates in the satellite frequency band, the switch is in the off state, disconnecting the first grounding member from the floor, and first radiator 211 is not coupled to the floor. First radiator 211 only generates a linear DM mode, and the resonance generated by the linear DM mode of antenna 200 has higher radiation efficiency and system efficiency. When electronic device 10 does not operate in the satellite frequency band, the switch is in the on state, short-circuiting the first grounding member from the floor, and first radiator 211 is coupled to the floor, thereby achieving better isolation between the second antenna and the fourth antenna.

[0359] In one embodiment, the first grounding member may include a first elastic sheet and a second elastic sheet. Electronic components are coupled between the first elastic sheet, the second elastic sheet, and the ground. The equivalent capacitance of each electronic component is greater than or equal to 3 pF.

[0360] In one embodiment, when the first grounding member is connected to the floor through the electronic component, the width of the first grounding member can be greater than or equal to 1.5 mm and less than or equal to 12 mm. In one embodiment, the width of the first grounding member can be greater than or equal to 2 mm and less than or equal to 8 mm.

[0361] It should be understood that when the first grounding member is coupled to the floor through an electronic component, the width of the first grounding member can be understood as the distance (the length of the frame) between the midpoint of one end of the first spring clip coupled to the first radiator 211 and the midpoint of one end of the second spring clip coupled to the first radiator 211. For the sake of simplicity, the embodiment of the present application only uses the example of the first grounding member including two spring clips. In actual production or design, multiple spring clips can also be included (multiple spring clips are coupled to the floor and connected to electronic components). The first spring clip and the second spring clip can be understood as the two spring clips farthest apart among the multiple spring clips.

[0362] In one embodiment, when the first grounding member is coupled to the floor via an electronic component, the electronic device 10 may further include a SAR sensor. The SAR sensor may be electrically connected between the electronic component and the floor, with the first radiator 211 serving as the sensor. The SAR sensor is used to determine the distance between the human body and the electronic device 10 (first radiator 211).

[0363] 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 state.

[0364] In one embodiment, when an electronic component is coupled between the first grounding member and the floor, the frequency difference between the resonance point of the second resonance and the resonance point of the first resonance, and / or the frequency difference between the resonance point of the fourth resonance and the resonance point of the third resonance can be determined based on the center frequency of the operating frequency band of the antenna 200.

[0365] 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 part of the frequency band in the Tiantong satellite system and at least part of the frequency band in the Beidou satellite system. The frequency difference between the resonance point of the second resonance and the resonance point of the first resonance is less than or equal to 500 MHz, and / or the frequency difference between the resonance point of the fourth resonance and the resonance point of the third resonance is less than or equal to 500 MHz. The frequency difference between the resonance point of the second resonance and the resonance point of the first resonance is greater than or equal to 50 MHz, and / or the frequency difference between the resonance point of the fourth resonance and the resonance point of the third resonance is greater than or equal to 50 MHz.

[0366] 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 part of the frequency band in other systems. The frequency difference between the resonance point of the second resonance and the resonance point of the first resonance is less than or equal to 1200 MHz, and / or the frequency difference between the resonance point of the fourth resonance and the resonance point of the third resonance is less than or equal to 1200 MHz. The frequency difference between the resonance point of the second resonance and the resonance point of the first resonance is greater than or equal to 100 MHz, and / or the frequency difference between the resonance point of the fourth resonance and the resonance 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 by a second grounding piece. The width of the connection between the second grounding piece and the frame is greater than or equal to 2 mm and less than or equal to 12 mm.

[0367] It should be understood that providing a grounding structure at the second grounding point 242 can be used to improve the isolation between the second antenna and the third antenna.

[0368] 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 to serve as another antenna. This antenna can be used to increase the communication frequency band of the electronic device.

[0369] Figures 11 to 15 are simulation results for antenna 200 shown in Figure 10 . Figure 11 shows the S-parameter simulation results for antenna 200 shown in Figure 10 . Figure 12 shows the simulation results for system efficiency and radiation efficiency for antenna 200 shown in Figure 10 . Figure 13 shows the current distribution corresponding to the quarter-wavelength mode of antenna 200 shown in Figure 10 at 2.2 GHz. Figure 14 shows the current distribution corresponding to the CM mode of antenna 200 shown in Figure 10 at 2.2 GHz. Figure 15 shows the current distribution corresponding to the DM mode of antenna 200 shown in Figure 10 at 2.2 GHz.

[0370] It should be understood that Figures 11 to 15 illustrate simulation results for the first radiator in different operating modes. The third, fourth, and fifth connection points are grounded (directly electrically connected to the ground via the third, fourth, and fifth tuning circuits, or electrically connected via a 0 ohm resistor). This prevents the second, third, and fourth radiators from affecting the first radiator. Accordingly, the first and second tuning circuits are in different circuit states (e.g., electrically connected to different electronic components), enabling the first radiator to operate in different operating modes at 2.2 GHz.

[0371] For the sake of simplicity, the embodiments of the present application only take the first radiator forming a structure similar to a left-handed antenna (the length of the frame between the first feeding point and the second position is less than half the length of the frame (conductor part) between the second position and the first grounding point) and working in the quarter-wavelength mode of the left-handed antenna as an example for explanation. The left-handed antenna can be, for example, an antenna that conforms to a composite right and left hand (CRLH) transmission line structure.

[0372] When the first radiator operates in quarter-wavelength mode, the first connection point is grounded (directly electrically connected to the ground plane via the first tuning circuit or electrically connected via a 0 ohm resistor). The frame between the first ground point and the first position acts as a ground branch and does not participate in radiation. When the first radiator operates in CM mode or DM mode, the first tuning circuit and the second tuning circuit are in different circuit states (for example, different electronic components are electrically connected between the connection point and the ground plane), so that the 2.2 GHz frequency corresponds to the CM mode or the DM mode.

[0373] As shown in FIG11 , the first radiator can resonate at 2.2 GHz in the quarter-wavelength mode, the CM mode, and the DM mode.

[0374] As shown in Figure 12, 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 approximately 0.5 dB higher than those of the CM mode.

[0375] As shown in FIG13 , the border between the second position and the first ground point may correspond to the aforementioned quarter-wavelength mode.

[0376] As shown in FIG14 , when the first radiator resonates, the current in the CM mode on the radiator can excite the transverse mode on the floor. However, the currents generated by the transverse modes cancel each other out, resulting in low system efficiency and radiation efficiency in the CM mode.

[0377] As shown in Figure 15, when the first radiator resonates, radiation primarily originates from the border between the first and second positions. This also excites the transverse mode in the floor. The currents generated in these transverse modes are in the same direction and do not cancel each other out, resulting in higher system efficiency and radiation efficiency in the DM mode.

[0378] When the first frame is located at the center of the second side, the transverse mode can be excited (occupying a larger proportion than the longitudinal mode), but the currents corresponding to the transverse modes will cancel each other out. Therefore, the system efficiency and radiation efficiency of the CM mode are low.

[0379] Figures 16 to 19 are schematic diagrams of the current and electric field distribution of the antenna 200 shown in Figure 10 (back view). Figure 16 is a schematic diagram of the current distribution of the antenna 200 shown in Figure 10 when the third connection point 2131 is grounded (back view). Figure 17 is a schematic diagram of the current distribution of the antenna 200 shown in Figure 10 when the third connection point 2131 is not grounded (back view). Figure 18 is a schematic diagram of the electric field distribution of the antenna 200 shown in Figure 10 when the third connection point 2131 is grounded (back view). Figure 19 is a schematic diagram of the electric field distribution of the antenna 200 shown in Figure 10 when the third connection point 2131 is not grounded (back view).

[0380] It should be understood that Figures 16 to 19 illustrate schematic diagrams of the currents between the third radiator and the first radiator forming a similar array during a current cycle T at 2.2 GHz when the antenna is radiating. The fourth and fifth connection points are grounded (the fourth and fifth connection points are electrically connected to the ground directly or through a 0 ohm resistor via the fourth and fifth tuning circuits) to prevent the second and fourth radiators from affecting the current and electric field distribution. The first and second tuning circuits are in corresponding tuning circuit states, so that the first radiator operates in DM mode at 2.2 GHz.

[0381] As shown in Figure 16, the third connection point is grounded (the third connection point is directly electrically connected to the floor through the third tuning circuit or electrically connected through a 0ohm resistor). The third radiator can serve as a grounded branch and does not participate in the current distribution diagram when radiating. The current is mainly concentrated on the first radiator.

[0382] Figure 17 shows a schematic diagram of current distribution in a case where an electronic component is electrically connected between the third tuning circuit and the floor (the resonance frequency of the first parasitic resonance generated by the third radiator is lower than the resonance frequency of the first resonance generated by the first radiator). At the resonance point of the second resonance (2.2 GHz), the current flowing through the first radiator and the current flowing through the third radiator are in the same direction, extending the path of the current generated by the first radiator.

[0383] As shown in FIG18 , when the third radiator serves as a grounded branch, the electric field near the third radiator is relatively weak.

[0384] As shown in FIG19 , when an electronic component is electrically connected between the third tuning circuit and the floor (the resonance point frequency of the first parasitic resonance generated by the third radiator is lower than the resonance point frequency of the first resonance generated by the first radiator), the electric field near the third radiator is stronger.

[0385] Figures 20 to 23 are simulation results of the directivity patterns of antenna 200 shown in Figure 10. Figure 20 is the directional gain pattern of antenna 200 shown in Figure 10 when the third connection point is grounded. Figure 21 is the left-handed circularly polarized directivity pattern of antenna 200 shown in Figure 10 when the third connection point is grounded. Figure 22 is the directional gain pattern of antenna 200 shown in Figure 10 when the third connection point is not grounded. Figure 23 is the left-handed circularly polarized directivity pattern of antenna 200 shown in Figure 10 when the third connection point is not grounded.

[0386] It should be understood that the directional pattern simulation results shown in Figures 20 to 23 are all simulation results when the electronic device is placed on a human hand model.

[0387] As shown in Figure 20, when the third radiator is used as a grounded branch, the directional gain of the antenna is 4.05 dBi. The maximum radiation direction of the radiation generated by the antenna deviates from the top of the electronic device (for example, the y direction).

[0388] As shown in FIG21 , when the third radiator serves as a grounded branch, the left-hand circular polarization directional gain of the antenna is 1.1 dBic.

[0389] As shown in Figure 22, when an electronic component is electrically connected between the third tuning circuit and the floor (the resonance point frequency of the first parasitic resonance generated by the third radiator is lower than the resonance point frequency of the first resonance generated by the first radiator), since the current on the first radiator and the current on the third radiator are in the same direction, the current between the third radiator and the first radiator forms a similar array. Compared with the gain radiation pattern shown in Figure 20, the maximum radiation direction of the radiation generated by the antenna is close to the top of the electronic device (for example, the y direction), and the directional gain is increased from 4.05dBi to 4.8dBi.

[0390] As shown in FIG23 , when an electronic component is electrically connected between the third tuning circuit and the floor, the left-hand circular polarization directional gain of the antenna is increased from 1.1 dBic to 1.9 dBic.

[0391] Figures 24 and 25 are simulation results of the antenna 200 shown in Figure 10. Figure 24 is the S-parameter simulation result of the antenna 200 shown in Figure 10. Figure 25 is the simulation result of the system efficiency and radiation efficiency of the antenna 200 shown in Figure 10.

[0392] It should be understood that Figures 24 and 25 illustrate simulation results for the antenna 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 floor), the resonances generated by the antenna include the first resonance and the 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 floor), the resonances generated by the antenna include the third resonance and the fourth resonance.

[0393] Correspondingly, the third tuning circuit can be in a first circuit state and a second circuit state when the first radiator generates a second resonance and a fourth resonance respectively, so that the resonance point frequency of the parasitic resonance generated by the third radiator is within the range described in the above embodiment with respect to the resonance point frequency of the second resonance and the resonance point frequency of the fourth resonance, so as to improve the directivity of the antenna.

[0394] Moreover, the fourth tuning circuit can be in a first circuit state and a second circuit state when the first radiator generates a second resonance and a fourth resonance respectively, so that the resonance point frequency of the parasitic resonance generated by the fourth radiator is within the range described in the above embodiment as well as the resonance point frequency of the second resonance and the resonance point frequency of the fourth resonance, so as to improve the radiation efficiency and system efficiency of the antenna.

[0395] It should be understood that since the gain of an antenna is related to its directivity and efficiency (radiation efficiency and system efficiency), when the efficiency (radiation efficiency and system efficiency) of an antenna is improved, the gain of the antenna can also be increased while the directivity remains unchanged.

[0396] The fifth tuning circuit can electrically connect the fifth connection point to the ground directly or through a 0 ohm resistor, and the fourth radiator is coupled to the ground at the fifth connection point to prevent the fourth radiator from interfering with satellite communications.

[0397] As shown in Figure 24, when the first feeding circuit feeds an electrical signal, the antenna can generate two resonances when the first tuning circuit and the second tuning circuit are in different circuit states. When the first and second tuning circuits are in the first circuit state, the resonances generated by the antenna include a first resonance (near 1.7 GHz) and a second resonance (near 2 GHz). With S11 < -6 dB as the limit, the antenna's operating frequency range can include 1980 MHz to 2010 MHz.

[0398] When the first tuning circuit and the second tuning circuit are in the second circuit state, the resonance generated by the antenna includes the third resonance (near 2 GHz) and the fourth resonance (near 2.2 GHz). With S11 < -6 dB as the limit, the operating frequency band of the antenna can include 2170 MHz-2200 MHz.

[0399] As shown in Figure 25, since the first radiator operates in DM mode at 1980MHz-2010MHz and 2170MHz-2200MHz, 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.

[0400] FIG26 is a schematic diagram of another electronic device 10 provided in an embodiment of the present application.

[0401] As shown in Figure 26, the frame 11 may further include a fourth position 204, a third grounding point 243 located between the first position 201 and the fourth position 204, and a fourth slot defined in the fourth position 204. The antenna 200 also includes a fifth radiator 215, which comprises at least a portion of the frame between the third grounding point 243 and the fourth position 204. The fifth radiator 215 is configured to generate a third parasitic resonance, the resonant frequency of which is lower than the resonant frequency of the first main resonance.

[0402] It should be understood that the electronic device 10 shown in FIG. 26 differs from the electronic device 10 shown in FIG. 10 only in that a fourth slot is provided at the fourth position 204 so that the antenna 200 includes a fifth radiator 215 .

[0403] In the technical solution provided in the embodiments of the present application, when the first radiator 211 generates a first main resonance in a linear DM mode, it can excite the fifth radiator 215 to generate a fifth parasitic resonance. In one embodiment, when an electrical signal is fed into the first feeding circuit 221, at the resonance point of the first main resonance, the current flowing through the first radiator 211 and the current flowing through the fifth radiator 215 are in the same direction, extending the path of the current generated by the first radiator 211. The unidirectional currents flowing through the first radiator 211, the third radiator 213, and the fifth radiator 215 can achieve a current array-like effect, further improving the directivity of the antenna 200.

[0404] 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 the following relationship: L1≤L3≤L1×120%.

[0405] In one embodiment, the fifth radiator 215 may further include a sixth connection point 2151 . The electronic device 10 may further include a sixth tuning circuit 256 . The sixth tuning circuit 256 is coupled to the sixth connection point 2151 .

[0406] It should be understood that the sixth tuning circuit 256 can be used to adjust the resonance point frequency of the resonance generated by the fifth radiator 215 so that the fifth radiator 215 generates a fifth parasitic resonance and a 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, and obtaining an effect similar to a current array, which can improve the directivity of the antenna 200.

[0407] In one embodiment, the frequency difference between the resonance point of the first main resonance and the resonance point of the fifth parasitic resonance is less than or equal to 200 MHz. In one embodiment, the frequency difference between the resonance point of the second main resonance and the resonance point of the sixth parasitic resonance is less than or equal to 200 MHz.

[0408] It should be understood that when the frequency difference between the resonance point of the first main resonance (or the second main resonance) and the resonance point of the fifth parasitic resonance (or the sixth parasitic resonance) is less than or equal to 200 MHz, the first feeding circuit 221 feeds an electrical signal, and at the resonance point of the first main resonance (or the second main resonance), the current generated on the fifth radiator 215 and the current on the first radiator 211 in the same direction account for a larger proportion, which can further improve the directivity of the antenna 200.

[0409] In one embodiment, the frame 11 may include a third side 133 intersecting 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 at the third side 133.

[0410] In one embodiment, the fifth radiator 215 may further include a fifth feeding point 235. The electronic device 10 may further include a fifth feeding circuit 225. The fifth feeding circuit 225 is coupled to the fifth feeding point 235. In one embodiment, the fifth feeding point 235 is located between the sixth connection point 2151 and the third ground point 243.

[0411] It should be understood that when the antenna 200 does not perform satellite communication, the fifth radiator 215 and the fifth feeding circuit 225 may form a fifth antenna, which may operate in a quarter-wavelength mode.

[0412] In one embodiment, the length R5 of the fifth radiator 215 (the length of the frame between the fourth position 204 and the third ground 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%.

[0413] In one embodiment, the operating frequency band of the fifth antenna may include at least part of the frequency band in the middle band (MB) (1710MHz-2170MHz) and / or at least part of the frequency band in the high band (HB) (2300MHz-2690MHz), for example, B1 (1920MHz-1980MHz), B3 (1710MHz-1785MHz) and B7 (2500MHz-2570MHz) in LTE.

[0414] 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 floor.

[0415] At the same time, the fifth radiator 215 resonates when the electronic device performs satellite communication or not. When the electronic device 10 performs satellite communication, the fifth antenna does not work as the main feed antenna, and the fifth radiator 215 generates parasitic resonance by indirectly coupling with the first radiator 211, thereby improving the radiation characteristics of the antenna 200 (for example, the frequency difference between the resonance point of the parasitic resonance and the resonance point of the main resonance is within the above range). When the electronic device 10 does not perform satellite communication, the fifth antenna works as the main feed antenna, and the fifth radiator 215 can resonate with the fed electrical signal, and the resonance point frequency of the resonance is different from the resonance point frequency of the parasitic resonance.

[0416] In one embodiment, grounding can be achieved through a third grounding member at the third grounding point 243. The width of the connection between the third grounding member and the frame is greater than or equal to 1 mm and less than or equal to 20 mm.

[0417] It should be understood that the grounding structure at the third grounding point 243 can be used to improve the isolation between the fourth antenna and the fifth antenna.

[0418] 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.

[0419] It should be understood that for the sake of simplicity of discussion, in the embodiments of the present application, only the operating frequency bands of the first antenna, the second antenna, the third antenna, the fourth antenna, and the fifth antenna include the above-mentioned frequency bands as an example for illustration. In actual production or design, the operating frequency bands of the first antenna, the second antenna, the third antenna, the fourth antenna, and the fifth antenna may include other frequency bands, and the embodiments of the present application do not limit this.

[0420] In an embodiment of the present application, the first antenna and the antenna 200 use the same feeding circuit (first feeding circuit) to feed the electrical signal. When the electronic device 10 performs satellite communication, the feeding circuit cannot feed the electrical signal of the first antenna, and therefore, the first antenna does not work. In one embodiment, the first antenna is used to feed the signal of the L1 frequency band in GPS, and the antenna 200 for satellite communication and the first antenna of the L1 frequency band of GPS do not work at the same time. In one embodiment, the first antenna is used to feed the signal of the Wi-Fi 2.4GHz frequency band, and the antenna 200 for satellite communication and the first antenna of the Wi-Fi 2.4GHz frequency band do not work at the same time. Similarly, the first antenna can also be used to feed signals of other frequency bands, which will not be repeated here.

[0421] When electronic device 10 performs satellite communication, at least some of the operating frequency bands of the second antenna (e.g., the 2.4 GHz band or the N77 band of WiFi), 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) are close to the first or second main resonance of antenna 200 (e.g., the difference between the center frequency of some of the operating frequency bands and the resonant point frequency of the main resonance is less than or equal to 200 MHz). This results in poor isolation between the second, third, fourth, and fifth antennas and antenna 200 (e.g., the isolation from antenna 200 is less than 25 dB). When antenna 200 resonates and the second, third, fourth, and fifth antennas are operating, some power is injected into the corresponding feed circuits from the feed points of the second, third, fourth, and fifth antennas, causing damage to some components in the feed circuits.

[0422] In one embodiment, the operating frequency band of the second antenna, the third antenna, the fourth antenna, or the fifth antenna is not adjacent to the first main resonance or the second main resonance of the antenna 200 (for example, the difference between the center frequency of some frequency bands in the operating frequency band and the resonance point frequency of the main resonance is greater than 200 MHz). When the electronic device 10 performs satellite communication, the second antenna, the third antenna, the fourth antenna, or the fifth antenna can operate simultaneously with the antenna 200.

[0423] In one embodiment, the operating frequency band of the second antenna, the third antenna, the fourth antenna, or the fifth antenna may include the L1 frequency band of GPS. Since the L1 frequency band of GPS is not adjacent to the frequency band used in satellite communications and has good isolation, antennas including the L1 frequency band of GPS can operate simultaneously with antenna 200. While electronic device 10 is performing satellite communications (sending or receiving short messages, voice communications), it can also perform positioning.

[0424] In one embodiment, the electronic device 10 may further include an antenna 400 and an antenna 500 , as shown in FIG. 27 .

[0425] The operating frequency band of antenna 400 may include the BT band (2.4 GHz-2.4835 GHz). The operating frequency band of antenna 500 may include at least part of the middle band (MB) (1710 MHz-2170 MHz) and / or at least part of the high band (HB) (2300 MHz-2690 MHz), for example, B1 (1920 MHz-1980 MHz), B3 (1710 MHz-1785 MHz), and B7 (2500 MHz-2570 MHz) in LTE.

[0426] In one embodiment, the distance between antenna 400 and the first radiator in antenna 200 along the extension direction of first side 131 or the extension direction of third side 133 may be greater than one-sixth of the length of first side 131 or third side 133. In one embodiment, antenna 400 may be located near a side key of electronic device 10.

[0427] In one embodiment, the distance between the antenna 500 and the first radiator in the antenna 200 along the extending direction of the first side 131 or the extending direction of the third side 133 may be greater than half the length of the first side 131 or the third side 133 .

[0428] 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 first side 131 or the extension direction of third side 133 can be greater than one-sixth of the length of first side 131 or third side 133, antenna 400 and antenna 200 can have good isolation, and both can operate simultaneously. In one embodiment, electronic device 10 can establish a Bluetooth connection with an external wearable device (e.g., headphones or a watch) via antenna 400.

[0429] 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 antenna 500 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 half the length of the first side 131 or the third side 133, there can be good isolation between antenna 500 and antenna 200, and both can work simultaneously.

[0430] FIG28 is a schematic diagram of a graphical user interface of an electronic device 10 provided in an embodiment of the present application.

[0431] It should be understood that for the sake of simplicity of discussion, in the embodiments of the present application, only the operating frequency bands of the first antenna, the second antenna, the third antenna, the fourth antenna, and the fifth antenna include the above-mentioned frequency bands as an example for illustration. In actual production or design, the operating frequency bands of the first antenna, the second antenna, the third antenna, the fourth antenna, and the fifth antenna may include other frequency bands, and the embodiments of the present application do not limit this.

[0432] When the electronic device 10 does not perform satellite communication, the electronic device 10 can communicate through the first antenna, the second antenna, the third antenna, the fourth antenna or the fifth antenna in the above embodiment, and can communicate through the 4G / 5G frequency band and WiFi in the cellular network and be positioned through GPS, as shown in (a) in Figure 28.

[0433] When the user is ready to conduct satellite communication, the satellite communication application is started, as shown in (b) in FIG28 .

[0434] It should be understood that in the embodiment of the present application, only the graphical user interface shown in (b) in Figure 28 is used as an example for explanation, and adjustments can also be made to this in actual production or design.

[0435] When the user turns on satellite communication, the graphical user interface reminds the user of the frequency band information that will be turned off, as shown in (c) in Figure 28.

[0436] It should be understood that when the user turns on satellite communication, the electronic device 10 can turn off some antennas related to the antenna 200 in the above embodiment. For example, the second antenna (e.g., WiFi 2.4 GHz band, N77 band), 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) in the above embodiment.

[0437] At the same time, some antennas in the electronic device 10 may not be turned off. For example, antenna 400 and antenna 500 in the above embodiment. The electronic device 10 can establish a Bluetooth connection with an external wearable device (e.g., headphones or a watch) through antenna 400. Alternatively, when the operating frequency band of the second antenna, third antenna, fourth antenna, or fifth antenna in the above embodiment is not close to the first main resonance or second main resonance of antenna 200, it can operate simultaneously with satellite communication.

[0438] After the user turns on satellite communication, the user can perform satellite alignment according to the steps displayed on the graphical user interface to perform satellite communication, as shown in (d) in Figure 28.

[0439] FIG29 is a schematic diagram of another electronic device 10 provided in an embodiment of the present application.

[0440] As shown in FIG29 , the frame 11 may include a second position 202 located at the second side 132, a third position 203 located at the first side 131, and a second grounding point 242. The frame 11 may have gaps formed in the second position 202 and the third position 203. The frame 11 may be coupled to the floor 300 at the second grounding point 242.

[0441] Antenna 200 may include a first radiator 211, a first feeding circuit 221, a first tuning circuit 251, and a second tuning circuit 252. First radiator 211 is a conductive portion of the frame between second position 202 and third position 203. A first end (the end near second position 202) and a second end (the end near third position 203) of first radiator 211 are open ends.

[0442] The first radiator 211 includes a first feeding point. The distance between the first feeding point and the second position 201 is different from the distance between the first feeding point and the third position 203, so that the first radiator 211 generates both a line CM mode and a line DM mode. A first feeding circuit 221 is coupled to the first feeding point and is used to feed an electrical signal to stimulate the antenna 200 to resonate. The difference between the distance between the first feeding point and the second position 202 and the distance between the first feeding point and the third position 203 can also be understood as the difference between the length of the first radiator 211 between the first feeding point and the first end and the length between the first feeding point and the second end.

[0443] 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 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.

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

[0445] In one embodiment, the first tuning circuit 251 and the second tuning circuit 252 are in the second circuit state, and the first radiator 211 is used to generate a second main resonance, where the resonant frequency band of the second main resonance includes the second frequency band. In one embodiment, the first tuning circuit 251 and the second tuning circuit 252 are in the second circuit state, and the first radiator 211 is used to generate a third resonance and a fourth resonance, where the resonant point frequency of the third resonance is lower than the resonant point frequency of the fourth resonance, and the fourth resonance is the second main resonance.

[0446] It should be understood that the technical solutions provided in the embodiments of this application can simultaneously excite the line CM mode and the line DM mode of the first radiator 211. In the first circuit state, the first resonance is primarily generated by the line CM mode, and the second resonance is primarily generated by the line DM mode. In the second circuit state, the third resonance is primarily generated by the line CM mode, and the fourth resonance is primarily generated by the line DM mode.

[0447] Compared to when the entire first radiator 211 is located on the second side 132, when the second portion of the first radiator 211 is located on the second side 132, the radiation efficiency and system efficiency of the resonance generated by the linear DM mode of the antenna 200 are reduced, but still provide good performance. Since the gain of an antenna is related to its directivity and efficiency (radiation efficiency and system efficiency), improving the antenna's efficiency (radiation efficiency and system efficiency) while maintaining its directivity can also improve the antenna's gain.

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

[0449] In one embodiment, the frequency difference between the resonance point of the fourth resonance and the resonance point of the third resonance is less than or equal to 300 MHz. In one embodiment, the frequency difference between the resonance point of the fourth resonance and the resonance point of the third resonance is greater than or equal to 100 MHz.

[0450] 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 of the length of the second portion of the first radiator 211 on the second side 132, and less than or equal to three half of the length of the second portion of the first radiator 211 on the second side 132.

[0451] It should be understood that in the antenna 200 shown in FIG29 , the connecting region between the first and second portions of the first radiator 211 is shaped like a broken line. 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 connecting region, and the length of the second portion can be understood as the length between the second position 202 and the connecting region. In one embodiment, the connecting 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 the length extending in the direction of the first side 131, and the length of the second portion can be understood as the length extending in the direction of the second side 132.

[0452] When the first radiator 211 is bent and the length of the first portion on the first side 131 and the length of the second portion on the second side 132 are within the above range, the resonance generated by the line DM mode has better radiation efficiency and system efficiency.

[0453] The antenna 300 shown in FIG. 29 differs from the antenna 200 shown in the above embodiment only in the position of the main radiator (the radiator that feeds the electrical signal) when performing satellite communication.

The structure of the same frame 11 can also be understood as follows: the length ratio of the frame between the first position 201, the second position 202, the third position 203, and the fourth position 204 is the same. The structure of the same frame 11 can also be understood as follows: the width of the frame connected to the grounding member at the first grounding point 241, the second grounding point 242, and the third grounding point 243.

[0456] 29 , the third position 203 is located at the first side 131 of the frame 11, and the second position 202 is located at the second side. The first radiator 211 is bent, for example, L-shaped.

[0457] 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 ground point 242 and the first end. In one 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 ground point 242 and the second position 202 on the first radiator 211.

[0458] In one embodiment, the length D1 of the frame between the first connection point 2111 and the second position 202 and the length L1 of the frame between the third position 203 and the second position 202 satisfy the following conditions: D1 ≤ L1 × 30%. In one embodiment, D1 ≤ L1 × 10%. In one embodiment, D1 is less than or equal to 8 mm.

[0459] 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 ground point 242 and the second end.

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

[0461] In one embodiment, in the antenna 200 shown in FIG29 , the 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 first ground point 241, and the third radiator 213 is a conductive portion of the frame between the second ground point 242 and the first position 201.

[0463] It should be understood that in the embodiment shown in Figure 29, the first radiator 211 is taken as the conductive part of the frame between the second position 202 and the third position 203 for illustration. In actual production or application, the conductive part of the frame between the first position 201 and the fourth position 204 can also be used as the first radiator 211. For the sake of simplicity, they will not be described one by one, as shown in Figure 30.
