Description

An electronic device

[0001] This application claims priority to the Russian patent application with application number 2023135528, entitled “An electronic device”, filed with the Russian Patent Office on December 27, 2023, and the Russian patent application with application number 2024102459, entitled “An electronic device”, filed with the Russian Patent Office on January 31, 2024, the entire contents of which are incorporated herein by reference. 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 the frame as an antenna radiator. For example, in satellite communication systems, frame radiators are primarily used to form linearly polarized antennas. When using satellite communication, users need to point the antenna's area with good radiation characteristics (for example, the antenna's gain within this area is greater than or equal to AdBic, where A is the minimum gain required to meet communication requirements in the satellite communication system) toward the satellite to achieve satellite alignment (establishing a communication connection with the satellite).

[0004] However, during satellite communications, the relative position of the electronic device and the satellite changes. For example, if a low-orbit satellite moves, the satellite may move beyond the antenna's optimal radiation area. In this case, the user needs to adjust their grip or move the device to keep the satellite within the antenna's optimal radiation area to maintain tracking or establish a connection with a new satellite. Failure to do so can result in poor communication quality or even disconnection, significantly impacting the user's communication experience. Summary of the Invention

[0005] The present application provides an electronic device including an antenna. The antenna's operating frequency band includes a satellite communications frequency band. The antenna comprises at least a conductive portion of its frame as a radiator. The antenna can generate different maximum radiation directions to enhance the user experience during satellite communications.

[0006] In a first aspect, an electronic device is provided, which includes: a floor; a frame, the frame including a first position and a second position, the frame having a first insulating gap and a second insulating gap at the first position and the second position; an antenna, the antenna including: a radiator, the radiator including a conductive portion of the frame between the first position and the second position, at least a portion of the radiator being spaced apart from the floor; a feeding circuit, the radiator including a feeding point, the feeding circuit being coupled to the feeding point; a first switch branch, a second switch branch and a first switch, the radiator including a first connection point, the first switch branch, the second switch branch and the first switch being coupled between the first connection point and the floor, the first connection port of the first switch being coupled to the first switch branch, and the second connection port of the first switch being coupled to the The second switch branch is coupled; wherein the frame includes a first side and a second side intersecting at an angle, the first position and the second position are located on the first side, and the length of the first side is less than the length of the second side; the feeding point and the first connection point are respectively located on both sides of the virtual axis of the radiator, and the lengths of the radiators on both sides of the virtual axis are the same; based on the coupling of the first connection point and the first switch branch, the radiator is used to generate a first resonance; based on the coupling of the first connection point and the second switch branch, the radiator is used to generate a second resonance, wherein the resonant frequency band of the first resonance and the resonant frequency band of the second resonance include a first frequency band, and the first frequency band is a transmitting frequency band in the satellite communication frequency band, or the resonant frequency band of the first resonance and the resonant frequency band of the second resonance include a second frequency band, and the second frequency band is a receiving frequency band in the satellite communication frequency band.

[0007] According to an embodiment of the present application, the first connection point can be coupled to the first switch branch or the second switch branch, respectively, through the first switch. In this case, the antenna remains in the same operating state (for example, operating in the transmit frequency band and / or receive frequency band within the satellite communication frequency band). Coupling the first connection point to the first switch branch or the second switch branch does not change the operating frequency band of the antenna. Therefore, the antenna can perform satellite communication regardless of whether the first connection point is coupled to the first switch branch or the second switch branch.

[0008] At the same time, the first resonance and the second resonance are generated by the line DM mode described in the embodiment. Since the current generated by the line DM mode is mainly generated by the radiator and the current is mainly concentrated on the radiator, the current on the floor has little effect on the antenna, making it easy to determine the maximum radiation direction of the antenna's directional pattern.

[0009] In combination with the first aspect, in certain implementations of the first aspect, based on the coupling of the first connection point and the first switch branch, the antenna is used to generate a first radiation pattern, and the maximum radiation direction of the first radiation pattern is a first direction; based on the coupling of the first connection point and the second switch branch, the antenna is used to generate a second radiation pattern, and the maximum radiation direction of the second radiation pattern is a second direction, and the first direction and the second direction are different.

[0010] According to an embodiment of the present application, the antenna can have two directional patterns with different maximum radiation directions in the first frequency band. The antenna can switch the first directional pattern and the second directional pattern generated by the antenna according to the communication conditions (for example, including relative positions) between the communication satellite and the electronic device to switch the maximum radiation direction of the directional pattern generated by the antenna to ensure the communication quality between the communication satellite and the electronic device.

[0011] Therefore, the electronic device has good communication characteristics within a range of relatively large angles (e.g., 50°, 60°, or 70°) relative to the top direction (the direction from the bottom of the electronic device to the top, such as the z-direction). For example, when a user is performing satellite communication, the antenna has a wide beam characteristic, and the directional pattern generated by the antenna 200 has good characteristics within a relatively large angle, effectively improving the user experience.

[0012] In combination with the first aspect, in certain implementations of the first aspect, an angle between the first direction and the second direction is greater than or equal to 10° and less than or equal to 90°.

[0013] According to an embodiment of the present application, when the maximum radiation direction of the first radiation pattern and the maximum radiation direction of the second radiation pattern are offset toward both sides of the top direction (there is a larger angle between the first direction and the second direction), the width of the antenna radiation beam can be further widened, so that the antenna has good communication characteristics within a wider angle range (the angle with the top direction).

[0014] In combination with the first aspect, in some implementations of the first aspect, when the first switch branch and the second switch branch are capacitive, the equivalent capacitance value of the first switch branch is smaller than the equivalent capacitance value of the second switch branch; or, when the first switch branch and the second switch branch are inductive, the equivalent inductance value of the first switch branch is smaller than the equivalent inductance value of the second switch branch; or, the first switch branch can be capacitive and the second switch branch can be inductive.

[0015] In combination with the first aspect, in certain implementations of the first aspect, the first connection point is located on the first side of the virtual axis, and the feeding point is located on the second side of the virtual axis; based on the coupling of the first connection point and the first switch branch, the current on the floor on the first side of the virtual axis is greater than the current on the floor on the second side of the virtual axis; based on the coupling of the first connection point and the second switch branch, the current on the floor on the first side of the virtual axis is less than the current on the floor on the second side of the virtual axis.

[0016] According to an embodiment of the present application, when the current (e.g., current intensity, current density) on the floor on the first side of the virtual axis is greater than the current on the floor on the second side of the virtual axis, the directional pattern generated by the antenna is deflected toward the second side. When the current (e.g., current intensity, current density) on the floor on the first side of the virtual axis is less than the current on the floor on the second side of the virtual axis, the directional pattern generated by the antenna is deflected toward the first side. Therefore, with a larger angle between the first direction and the second direction, the width of the antenna radiation beam can be further widened, allowing the antenna to have good communication characteristics within a wider angle range (angle relative to the top direction).

[0017] In combination with the first aspect, in some implementations of the first aspect, the radiator includes a grounding point coupled to the floor, and the grounding point is located between the feeding point and the first connection point.

[0018] According to the embodiment of the present application, since the radiator is coupled to the floor at the grounding point, the coupling amount between the floor and the radiator is increased, thereby making the current difference between the first switch branch or the second switch branch and the first connection point coupled on the floor greater, thereby making the difference between the first radiation pattern and the second radiation pattern greater (for example, the angle between the maximum radiation directions increases), which can further widen the width of the antenna radiation beam, so that the antenna has good communication characteristics within a wider angle range (the angle with the top direction).

[0019] In combination with the first aspect, in certain implementations of the first aspect, based on the coupling of the first connection point with the first switching branch, the radiator is used to generate a third resonance, and there is a first frequency difference between the resonance point frequency of the first resonance and the resonance point frequency of the third resonance; based on the coupling of the first connection point with the second switching branch, the radiator is used to generate a fourth resonance, and there is a second frequency difference between the resonance point frequency of the second resonance and the resonance point frequency of the fourth resonance, and the second frequency difference is greater than the first frequency difference.

[0020] According to an embodiment of the present application, when the radiator is coupled to the floor at the grounding point, the radiator is coupled to different switch branches at the first connection point, thereby generating a third resonance and a fourth resonance in the line mode. The first switch branch and the second switch branch can also be used to adjust the frequency difference between the resonance point frequency of the resonance generated by the line CM mode and the resonance point frequency of the resonance generated by the line mode.

[0021] When the second switching branch is coupled to the first connection point, the frequency difference between the resonant frequency of the resonance generated by the line CM mode and the resonant frequency of the resonance generated by the line DM mode increases compared to when the first switching branch is coupled to the first connection point, thereby reducing the current on the floor on the first side of the virtual axis and increasing the current on the floor on the second side of the virtual axis. When the first switching branch is coupled to the first connection point, the frequency difference between the resonant frequency of the resonance generated by the line CM mode and the resonant frequency of the resonance generated by the line DM mode decreases compared to when the second switching branch is coupled to the first connection point, thereby increasing the current on the floor on the first side of the virtual axis and decreasing the current on the floor on the second side of the virtual axis.

[0022] In combination with the first aspect, in certain implementations of the first aspect, based on the coupling of the first connection point with the first switching branch, the radiator is used to generate a third resonance, and the resonance point frequency of the first resonance and the resonance point frequency of the third resonance have a first frequency difference; based on the coupling of the first connection point with the second switching branch, the radiator is used to generate a fourth resonance, and the resonance point frequency of the second resonance and the resonance point frequency of the fourth resonance have a second frequency difference, and the difference between the second frequency difference and the first frequency difference is greater than or equal to 100 MHz.

[0023] According to an embodiment of the present application, when the difference between the first frequency difference and the second frequency difference is within the above range, the antenna has a wider beam width, so that the antenna has good communication characteristics within a wider angle range (angle with the top direction).

[0024] In combination with the first aspect, in certain implementations of the first aspect, the first side or the second side includes a third position, and the second side includes a fourth position; the antenna further includes: a parasitic branch, the parasitic branch including a conductive portion of the frame between the third position and the fourth position, at least a portion of the parasitic branch being spaced apart from the floor; a third switch branch, a fourth switch branch, and a second switch, the parasitic branch including a second connection point, the third switch branch and the second switch being coupled and connected between the second connection point and the floor, a first connection port of the second switch being coupled to the third switch branch, and a second connection port of the second switch being coupled to the fourth switch branch; wherein, based on the first connection point being coupled to the first switch branch and the second connection point being coupled to the third branch, the antenna is configured to generate a first directional pattern, the maximum radiation direction of the first directional pattern being a first direction; based on the first connection point being coupled to the second switch branch and the second connection point being coupled to the fourth branch, the antenna is configured to generate a second directional pattern, the maximum radiation direction of the second directional pattern being a second direction, and the first direction and the second direction being different.

[0025] According to an embodiment of the present application, the first parasitic branch can be used to make the difference between the first radiation pattern and the second radiation pattern larger (for example, the angle between the maximum radiation directions is increased, for example, the angle between the first direction and the second direction is greater than or equal to 15°), which can further widen the width of the antenna radiation beam, so that the antenna has good communication characteristics within a wider angle range (angle with the top direction).

[0026] In combination with the first aspect, in certain implementations of the first aspect, the frame is coupled to the floor at a third position, and the frame defines a third insulating gap at the fourth position.

[0027] According to the embodiment of the present application, the first parasitic branch can have any structure, and the embodiment of the present application does not limit this.

[0028] In combination with the first aspect, in some implementations of the first aspect, the third position is located between the fourth position and the second position.

[0029] In combination with the first aspect, in certain implementations of the first aspect, based on the coupling of the first connection point with the first switch branch and the coupling of the second connection point with the third branch, the current on the floor on the first side of the virtual axis is greater than the current on the floor on the second side of the virtual axis, and the parasitic branch is located on the second side of the virtual axis; based on the coupling of the first connection point with the second switch branch and the coupling of the second connection point with the fourth branch, the current on the floor on the first side of the virtual axis is greater than the current on the floor on the second side of the virtual axis, and the parasitic branch is located on the second side of the virtual axis.

[0089] The following explains the terms that may appear in the embodiments of the present application.

[0090] It should be understood that the term "and / or" as used herein is simply a term used to describe the existence of three possible relationships between related objects. For example, "A and / or B" can represent the existence of A alone, the existence of both A and B, and the existence of B alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0091] 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.

[0092] 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.

[0093] Component / device: includes at least one of lumped component / device and distributed component / device.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] The radiator may include a conductor with a specific shape and size, such as a linear or sheet shape, etc., and the present application does not limit the specific shape. In one embodiment, the linear radiator can be simply referred to as a linear antenna. In one embodiment, the linear radiator can be implemented by a conductive frame, and can also be called a frame antenna. In one embodiment, the linear radiator can be implemented by a bracket conductor, and can also be called a bracket antenna. In one embodiment, the wire diameter (for example, including thickness and width) of the linear radiator, or the radiator of the linear antenna is much smaller than the wavelength (for example, the wavelength of the medium) (for example, less than 1 / 16 of the wavelength), and the length can be comparable to the wavelength (for example, the wavelength of the medium) (for example, the length is about 1 / 8 of the wavelength, or 1 / 8 to 1 / 4, or 1 / 4 to 1 / 2, or longer). The main forms of linear antennas include dipole antennas, half-wave oscillator antennas, monopole antennas, loop antennas, and inverted F antennas (also known as IFA, Inverted F Antenna). For example, for a dipole antenna, each dipole antenna typically includes two radiating branches, and each branch is fed by a feeding portion from the feeding end of the radiating branch. For example, an inverted-F antenna (IFA) can be regarded as a monopole antenna with a ground path added. The IFA antenna has a feeding point and a grounding point, and is called an inverted-F antenna because its side view is an inverted-F shape. In one embodiment, the sheet radiator may include a microstrip antenna, or a patch antenna, such as a planar inverted-F antenna (also known as a PIFA, Planar Inverted F Antenna). In one embodiment, the sheet radiator may be implemented by a planar conductor (such as a conductive sheet or a conductive coating, etc.). In one embodiment, the sheet radiator may include a conductive sheet, such as a copper sheet, etc. In one embodiment, the sheet radiator may include a conductive coating, such as a silver paste, etc. The shape of the sheet radiator includes circular, rectangular, annular, etc., and the present application does not limit the specific shape. The structure of a microstrip antenna generally consists of a dielectric substrate, a radiator, and a floor, wherein the dielectric substrate is arranged between the radiator and the floor.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] End / point: The "end / point" in the first end / second end / feeding end / grounding end / feeding point / grounding point / connection point of the antenna radiator should not be narrowly understood as an end point or end portion that is physically disconnected from other radiators, but can also be considered as a point or a section on a continuous radiator. In one embodiment, the "end / point" may include a connection / coupling area on the antenna radiator that is coupled to other conductive structures. For example, the feeding end / feeding point may be a connection / coupling area on the antenna radiator that is coupled to a feeding structure or a feeding circuit (for example, an area facing a portion of the feeding circuit). For another example, the grounding end / grounding point may be a connection / coupling area on the antenna radiator that is coupled to a grounding structure or a grounding circuit (for example, an area facing a portion of the grounding circuit).

[0109] 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).

[0110] 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).

[0111] 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.

[0112] 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.

[0113] The “suspended radiator” mentioned in the embodiments of the present application means that the radiator is not directly connected to the feed line / feed branch and / or the ground line / ground branch, but is fed and / or grounded through indirect coupling.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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:

[0121] Where L is the physical length and λ is the wavelength of the electromagnetic wave.

[0122] 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.

[0123] It should be understood that the wavelength of the radiation signal in air can be calculated as follows: (wavelength in air, or wavelength in vacuum) = speed of light / frequency, where frequency is the frequency of the radiation signal (MHz) and the speed of light can be taken as 3×108 m / s. The wavelength of the radiation signal in the medium can be calculated as follows: Wherein, ε is the relative dielectric constant of the medium. The wavelength in the embodiments of the present application generally refers to the dielectric wavelength, which can be the dielectric wavelength corresponding to the center frequency of the resonant frequency, or the dielectric wavelength corresponding to the center frequency of the working frequency band supported by the antenna. For example, assuming that the center frequency of the B1 uplink frequency band (resonant frequency is 1920MHz to 1980MHz) is 1955MHz, the wavelength can be the dielectric wavelength calculated using the frequency of 1955MHz. Not limited to the center frequency, "dielectric wavelength" can also refer to the dielectric wavelength corresponding to the non-center frequency of the resonant frequency or the working frequency band. For ease of understanding, the dielectric wavelength mentioned in the embodiments of the present application can be simply calculated by the relative dielectric constant of the medium filled on one or more sides of the radiator.

[0124] Antenna system efficiency (total efficiency): refers to the ratio of input power to output power at the antenna port.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] 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.

[0131] 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.

[0132] Beamwidth: This refers to the range of angles within a first angle range relative to the top of the electronic device (e.g., the z-direction) where the gain of the antenna's pattern is greater than or equal to a threshold. This first angle is the beamwidth. When the first angle is large, for example, greater than or equal to 30°, the antenna is considered to have a wide beam and exhibit good radiation characteristics within this angle range.

[0133] 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.

[0134] 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.

[0135] 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).

[0136] 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.

[0137] 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.

[0138] 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).

[0139] The technical solutions of the embodiments of the present application will be described below with reference to the accompanying drawings.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] Due to the compactness of electronic devices, a floor / grounding plate / grounding layer is typically provided within a 0-2mm internal space from the inner surface of the frame (for example, the printed circuit board, midframe, screen metal layer, battery, etc. can all be considered part of the floor). In one embodiment, a dielectric is filled between the frame and the floor, and the length and width of the rectangle enclosed by the inner surface contour of the dielectric filling can be simply considered the length and width of the floor. Alternatively, the length and width of the rectangle enclosed by the contour of all conductive parts within the frame can be considered the length and width of the floor.

[0145] 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.

[0146] The electronic device 10 may further include a frame 11, which may be made 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.

[0147] In one implementation, the frame 11, which primarily comprises a conductive material, can be referred to as a conductive frame or metal frame of the electronic device 10, and is suitable for use in industrial designs (IDs) with a metallic appearance. In one implementation, the outer surface of the frame 11 is primarily made of a conductive material, such as a metal material, thereby creating the appearance of a metallic frame. In these implementations, the conductive portion of the frame 11, including the outer surface, can serve as an antenna radiator for the electronic device 10 and is generally referred to as a frame antenna.

[0148] In another implementation, the outer surface of the frame 11 is primarily composed of a non-conductive material, such as plastic, creating a non-metallic frame appearance suitable for non-metallic IDs. In one implementation, the inner surface of the frame 11 may include a conductive material, such as metal. In this implementation, the conductive portion of the inner surface of the frame 11 can serve as an antenna radiator for the electronic device 10. It should be understood that the radiator (or, in other words, the conductive material on the inner surface) disposed on the inner surface of the frame 11 can be positioned adjacent to the non-conductive material of the frame 11 to minimize the volume occupied by the radiator and to be closer to the exterior of the electronic device 10, achieving better signal transmission. This can also be referred to as a frame antenna. It should be noted that the antenna radiator being positioned adjacent to the non-conductive material of the frame 11 means that the antenna radiator can be positioned closely to the inner surface of the non-conductive material, embedded within the non-conductive material, or positioned close to the inner surface of the non-conductive material, for example, with a small gap between the antenna radiator and the inner surface of the non-conductive material. It should be understood that both the conductive and non-conductive materials can be considered part of the frame 11.

[0149] It should be understood that there may be an insulating gap on the frame 11, and the conductive part of the frame between the two insulating gaps or the insulating gap and the grounding point serves as a radiator, thereby forming a frame antenna. When the frame 11 is formed of a conductive material such as metal, the insulating gap can be understood as a gap opened in the frame 11 filled with non-metallic material (insulating material). In this case, the gap is visible on the exterior surface. When the outer surface of the frame 11 is a non-conductive material, the insulating gap can be understood as a gap formed between two sections of radiators on the inner surface of the frame 11. Non-metallic material (insulating material) may be provided in the gap, or non-metallic material may not be provided, for example, it may be filled with air. In this case, the gap is not visible on the exterior surface.

[0150] 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.

[0151] The frame 11 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 have an aperture in this portion of the frame serving as the radiator to facilitate antenna radiation.

[0152] 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, screws, 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 between this part of the frame that serves as the radiator and the middle frame 19, thereby ensuring that the antenna radiator has a good radiation environment, so that the antenna has a good signal transmission function.

[0153] 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.

[0154] 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.

[0155] 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 in the form of an antenna based on a flexible printed circuit (FPC), an antenna based on laser-direct-structuring (LDS), or a microstrip disk antenna (MDA). In one embodiment, the antenna may also be a transparent structure embedded within the screen of electronic device 10, such that the antenna is a transparent antenna unit embedded within the screen of electronic device 10.

[0156] 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 .

[0157] 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.

[0158] 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.

[0159] It should be understood that the "common mode" or "CM mode" in this application includes the line common mode mode and the slot common mode mode, and the "differential mode mode" or "DM mode" in this application includes the line differential mode mode and the slot differential mode mode, which can be specifically determined according to the structure of the antenna.

[0160] It should be understood that the "common-differential mode" or "CM-DM mode" in this application refers to the line common mode and line differential mode generated on the same radiator, or refers to the slot common mode and slot differential mode generated on the same radiator, which can be specifically determined according to the structure of the antenna.

[0161] 1. Common mode (CM) mode

[0162] (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 grounded, 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).

[0163] 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 .

[0164] (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.

[0165] 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.

[0166] 2. Line differential mode (DM) mode

[0167] 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.

[0168] 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°.

[0169] (b) in FIG3 shows the current and electric field distribution of the antenna 50. As shown in (b) in FIG3, the current is distributed in the same direction on both sides of the middle position 51 of the antenna 50, for example, in an antisymmetric distribution; the electric field is distributed in opposite directions on both sides of the middle position 51. As shown in (b) in FIG3, the current at the feed line 52 is distributed in opposite directions. Based on the opposite distribution of the current at the feed line 52, the feeding shown in (a) in FIG3 can be called line 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 (b) in FIG3 can be called a line DM mode (it can also be simply referred to as a DM mode. For example, for a linear antenna, the DM mode refers to a line DM mode). The current and electric field shown in (b) in FIG3 can be respectively referred to as the current and electric field of the line DM mode.

[0170] The current is strong at the center 51 of the antenna 50 (the current is strong near the center 51 of the antenna 50) and weak at both ends of the antenna 50, as shown in FIG3(b). The electric field is weak at the center 51 of the antenna 50 and strong at both ends of the antenna 50.

[0171] 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.

[0172] 3. Line CM-DM mode

[0173] FIG2 and FIG3 above respectively show the line CM mode and line DM mode generated by adopting different feeding methods when both ends of the radiator are open.

[0174] 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).

[0175] FIG4 is a schematic diagram of a satellite communication usage scenario provided in an embodiment of the present application.

[0176] As shown in FIG4 , when a user performs satellite communication through an electronic device, it is necessary to point the area of ​​the electronic device's antenna with better radiation characteristics toward the satellite to achieve satellite alignment (establishing a communication connection with the satellite).

[0177] During satellite communications, the relative position of the electronic device and the satellite changes. For example, if a low-orbit satellite moves, the satellite may exceed the antenna's area of ​​good radiation characteristics (for example, the antenna has good radiation characteristics within a 30-degree angle from the top, but the satellite is located outside this area). In this case, the user needs to change the grip or move the device to keep the satellite within the antenna's area of ​​good radiation characteristics to maintain the satellite tracking status or establish a connection with a new satellite. Otherwise, the communication quality will be poor or even dropped, which will greatly affect the user's communication experience.

[0178] This application provides an electronic device including an antenna. The antenna's operating frequency band includes a satellite communications frequency band. The antenna utilizes at least a conductive portion of its frame as a radiator. The antenna can generate different maximum radiation directions, thereby enhancing the user experience during satellite communications.

[0179] It should be understood that the radiators and parasitic branches described in the embodiments of the present application may have different functions in different usage scenarios of the electronic device. For example, in the embodiments of the present application, the electronic device is taken as an example to perform communication under the first satellite system. In this usage scenario, the radiator and the parasitic branch are used to generate resonance and a directional pattern suitable for communication with the first satellite system. In other scenarios, for example, the electronic device does not perform satellite communication under the first satellite system, and the radiator and the parasitic branch can be used as radiators or parasitic branches of different communication systems, for example, the radiator or parasitic branch of the antenna in the cellular system, or the radiator or parasitic branch of the antenna in WiFi.

[0180] Therefore, the embodiments of the present application are related to electronic devices performing satellite communications, and any electronic device performing satellite communications (or having satellite communication functions) is applicable to the embodiments of the present application.

[0181] FIG5 is a schematic diagram of an electronic device 10 provided in an embodiment of the present application.

[0182] As shown in FIG. 5 , the electronic device 10 includes a frame 11 , an antenna 200 , and a floor 300 .

[0183] At least a portion of the frame 11 is spaced apart from the floor 300. The frame 11 includes a first position 201 and a second position 202. The frame 11 defines a first insulating gap and a second insulating gap at the first position 201 and the second position 202.

[0184] In one embodiment, the width of the first insulating gap is greater than or equal to 0.2 mm and less than or equal to 2 mm. It should be understood that the width of the gaps provided on the frame in the embodiments of the present application can be within the above ranges. For the sake of brevity, they are not detailed here. The "width of the insulating gap" should be understood as the dimension extending in the direction between two sections of conductive material (e.g., two radiators).

[0185] The frame 11 includes a first side 131 and a second side 132 that intersects the first side 131 at an angle. The length of the first side 131 is shorter than the length of the second side 132. The first position 201 and the second position 202 are located on the first side 131. In one embodiment, the first side 131 can be understood as a short side of the electronic device 10. When the electronic device 10 is a foldable electronic device including multiple housings, the first side 131 can be understood as a short side of the electronic device 10 when it is in a folded state.

[0186] It should be understood that the first side 131 can be the top side or the bottom side of the electronic device 10. For simplicity, the description will be given using the example where the first side 131 is the top side of the electronic device 10. The top side / bottom side of the electronic device 10 can be understood as the top / bottom side in normal use, for example, the top / bottom side of a mobile phone under a desktop or graphical user interface (GUI).

[0187] The antenna 200 includes a radiator 210 , a feeding circuit 220 , a first switch branch 231 , a second switch branch 232 , and a first switch 241 .

[0188] The radiator 210 includes a conductive portion of the frame 11 between the first position 201 and the second position 202. At least a portion of the radiator 210 is spaced apart from the floor 300.

[0189] The radiator 210 includes a feeding point 221 , and the feeding circuit 220 is coupled to the feeding point 221 to feed an electrical signal into the antenna 200 .

[0190] It should be understood that for the sake of simplicity of discussion, in the embodiments of the present application, only the electrical connection in the coupling connection is used as an example for explanation. In actual production or design, it can also be achieved through indirect coupling.

[0191] Radiator 210 includes a first connection point 211. A first switch branch 231, a second switch branch 232, and a first switch 241 are coupled between first connection point 211 and floor 300. A first connection port of first switch 241 is coupled to first switch branch 231, and a second connection port of first switch 241 is coupled to second switch branch 232.

[0192] For ease of understanding, the first switch branch 231 and the second switch branch 232 can be considered to be connected in parallel. In one embodiment, the first switch branch 231 and the second switch branch 232 are connected in parallel between the floor panel 300 and the first connection point 211. In one embodiment, the first switch branch 231 and the second switch branch 232 are both connected in parallel between the floor panel 300 and the first connection point 211 via the first switch 241.

[0193] It should be understood that the "first switch," "second switch," and "third switch" herein may include one or more switching devices; and the "first connection point," "second connection point," and "third connection point" herein may include one or more connection points. In one embodiment, the first switch branch 231 may be coupled between the floor 300 and the radiator 210 via a switching device in the first switch and a connection point in the first connection points 211; the second switch branch 232 may be coupled between the floor 300 and the radiator 210 via another switching device in the first switch and another connection point in the first connection points 211. In this embodiment, the switch is used only to switch between different switch branches coupled to the radiator / parasitic branch, and its specific location and form are not limited.

[0194] It should be understood that in the embodiment of the present application, the switch branch can be understood as a circuit between the switch and the connection point (for example, the first connection point 211) or the floor 300, which can be switched to different switch branches by the switch, so that the equivalent capacitance, equivalent resistance or equivalent inductance coupled to the connection point is different.

[0195] In one embodiment, the switch branch may include one or more electronic components, and the multiple electronic components may be connected in series or in parallel to achieve different equivalent capacitance values ​​and / or equivalent inductance values ​​and / or equivalent resistance values. In one embodiment, the switch branch may also include a switch to switch the equivalent capacitance values ​​and / or equivalent inductance values ​​and / or equivalent resistance values ​​in different states of the switch branch.

[0196] In one embodiment, the switch branch may not include electronic components. The switch branch can be used to determine the boundary conditions at the first connection point. For example, the switch branch is in an open circuit state. When the switch common port is connected to the switch branch, the first connection point 211 is in an open circuit state (not coupled to the floor 300 through a device). Alternatively, the switch branch is in a short circuit state. When the switch common port is connected to the switch branch, the first connection point 211 is in a short circuit state (electrically connected to the floor 300 and no other electronic components are provided). For the sake of simplicity, in the electronic device 10 shown in Figure 5, only the first switch branch 231 including an equivalent first electronic component and the second switch branch 232 including an equivalent second electronic component are used as an example for explanation.

[0197] The feeding point 221 and the first connection point 211 are respectively located on two sides of a virtual axis of the radiator 210 , and the lengths of the radiator 210 on both sides of the virtual axis are the same.

[0198] It should be understood that the two sides of the virtual axis described in the embodiment of the present application can be understood as the two sides of the plane formed by the virtual axis and the thickness direction of the electronic device 10 (for example, the direction perpendicular to the display screen) (for example, the x direction).

[0199] At the same time, due to production design requirements, the edge of the frame 11 facing the floor 300 (towards the inside of the electronic device 10) is not flat. Therefore, in the application embodiment, the virtual axis of the radiator 210 can be understood as a straight line passing through the center of the radiator 210 and perpendicular to the extension direction of the radiator 210.

[0200] When the first connection point 211 is coupled to the first switch branch 231, for example, the common port of the first switch 241 is coupled to the first connection port of the first switch 241, and the first switch branch 231 is coupled to the first connection point 211, the radiator 210 is configured to generate a first resonance, wherein the resonant frequency band of the first resonance includes a first frequency band, which is at least a portion of a satellite communication frequency band.

[0201] It should be understood that when the radiator 210 is arranged on the top or bottom edge of the electronic device 10, the resonant frequency band of the first resonance includes at least part of the frequency band within 1.5 GHz to 4.5 GHz, and the antenna 200 can have better radiation characteristics (for example, radiation efficiency, bandwidth, etc.).

[0202] Satellite communications include at least one of the following communication services: satellite receiving and / or sending short messages (also known as short messages), satellite calling and / or answering calls, and satellite data (such as Internet access).

[0203] In one embodiment, the satellite communication frequency band may include part of the frequency band in the Tiantong satellite system, and may include the transmit frequency band (1980MHz-2010MHz) and the receive frequency band (2170MHz-2200MHz) in the Tiantong satellite system. In one embodiment, the satellite communication frequency band may include part of the frequency band in the Beidou satellite system, and may include the transmit frequency band (1610MHz-1626.5MHz) and the receive frequency band (2483.5MHz-2500MHz) in the Beidou satellite system. In one embodiment, the satellite communication frequency band may include part of the frequency band in the low-orbit satellite system, and may include the transmit frequency band (1668MHz-1675MHz) and the receive frequency band (1518MHz-1525MHz) in the low-orbit satellite system. Alternatively, it may also be applied to other satellite communication systems, and the embodiments of the present application are not limited thereto.

[0204] It should be understood that when the electronic device 10 performs satellite communication, it can communicate with the communication satellite through one antenna or multiple antennas in the electronic device 10.

[0205] In one embodiment, when the electronic device 10 performs satellite communication, it can communicate with the communication satellite via an antenna within the electronic device 10. In this case, the antenna can be loaded with different electronic components at different time slots to adjust the resonant point frequency, thereby allowing the antenna to operate in the transmitting and receiving frequency bands of the satellite system.

[0206] In one embodiment, when the electronic device 10 performs satellite communication, it may communicate with a communication satellite through multiple antennas within the electronic device 10. In this case, the operating frequency bands of some of the multiple antennas may include the transmit frequency bands of the satellite system, and the operating frequency bands of other antennas may include the receive frequency bands of the satellite system.

[0207] 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 of 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 of the Beidou satellite system), the electronic device 10 can send or receive short messages and pictures through the antenna 200.

[0208] When the first connection point 211 is coupled to the second switch branch, for example, the common port of the first switch 241 is coupled to the second connection port of the first switch 241, the second switch branch 232 is coupled to the first connection point 211. The radiator 210 is configured to generate a second resonance, and the resonant frequency band of the second resonance includes the first frequency band.

[0209] According to an embodiment of the present application, when the first connection point 211 is coupled to the first switch branch 231 or the second switch branch 232 through the first switch 241, for example, the first electronic component or the second electronic component is coupled to the first connection point 211, the resonant frequency band of the resonance generated by the radiator 210 can include the first frequency band.

[0210] It should be understood that when the electronic device 10 communicates with a communication satellite via the antenna 200, the operating frequency band of the antenna 200 may include a transmit frequency band and a receive frequency band within the satellite communication frequency band. In one embodiment, the feed circuit 220 is configured to transmit radio frequency signals within a first frequency band and radio frequency signals within a second frequency band.

[0211] In one embodiment, at the first time / time period, the resonant frequency band of the first resonance and the resonant frequency band of the second resonance in the above embodiment include a first frequency band, and the first frequency band may be a transmission frequency band in a satellite communication frequency band.

[0212] In one embodiment, at the first time / time period, the resonant frequency band of the first resonance and the resonant frequency band of the second resonance in the above embodiment include a second frequency band, and the second frequency band may be a receiving frequency band in a satellite communication frequency band.

[0213] In one embodiment, the first frequency band may be at least a portion of a frequency band between 1.5 GHz and 4.5 GHz. In one embodiment, the antenna 200 operates in the Tiantong satellite system, and the first frequency band may be a transmit frequency band (1980 MHz-2010 MHz) therein. In one embodiment, the antenna 200 operates in the Beidou satellite system, and the first frequency band may be a transmit frequency band (1610 MHz-1626.5 MHz) therein. In one embodiment, the antenna 200 operates in a low-orbit satellite system (e.g., StarNet), and the first frequency band may be a transmit frequency band (1668 MHz-1675 MHz) therein.

[0214] In one embodiment, the second frequency band may be at least a portion of a frequency band between 1.5 GHz and 4.5 GHz. In one embodiment, the antenna 200 operates in the Tiantong satellite system, and the second frequency band may be a receiving frequency band (2170 MHz-2200 MHz) therein. In one embodiment, the antenna 200 operates in the Beidou satellite system, and the second frequency band may be a receiving frequency band (2483.5 MHz-2500 MHz) therein. In one embodiment, the second frequency band may be a receiving frequency band (1518 MHz-1525 MHz) therein.

[0215] In one embodiment, antenna 200 may further include a tuning circuit. This tuning circuit is coupled to radiator 210 and configured to adjust the resonant frequency of the resonance generated by radiator 210 so that the resonant frequency range of the first resonance and the resonant frequency range of the second resonance include the first frequency range or the second frequency range, thereby enabling antenna 200 to operate in the first frequency range and the second frequency range in different time slots. In one embodiment, the tuning circuit may include other switch branches coupled to the first connection point via first switch 241. This switch branch is configured to adjust the resonant frequency of the resonance generated by radiator 210 so that the resonant frequency range of the first resonance and the resonant frequency range of the second resonance include the first frequency range or the second frequency range. In one embodiment, the tuning circuit may include first switch branches 231 and second switch branches 232. The first switch branches 231 and second switch branches 232 may be configured to enable the resonant frequency range of the first resonance and the resonant frequency range of the second resonance generated by radiator 210 to include the first frequency range. Other switch branches may be configured to enable the resonant frequency range of the first resonance and the resonant frequency range of the second resonance generated by radiator 210 to include the second frequency range. For the sake of simplicity, in the embodiments of the present application, only the example of an antenna operating in a single frequency band is used for illustration.

[0216] When first connection point 211 is coupled to first switch branch 231 via first switch 241, antenna 200 generates a first directional pattern, where the maximum radiator direction of the first directional pattern is the first direction. In one embodiment, when antenna 200 generates the first directional pattern, it can be considered that radiator 210 and first switch branch 231 are used to generate the first directional pattern.

[0217] When first connection point 211 is coupled to second switch branch 232 via first switch 241, antenna 200 generates a second directional pattern, with the maximum radiator direction of the second directional pattern being the second direction. In one embodiment, antenna 200 generates the second directional pattern by radiator 210 and second switch branch 232. The first direction and the second direction are different.

[0218] It should be understood that in the embodiments of the present application (e.g., the electronic device 10 shown in FIG5 ), the antenna 200 is described as being in the same operating state. The same operating state can be understood as meaning that the operating frequency band of the antenna 200 includes either the first frequency band or the second frequency band, and the antenna 200 can communicate in the corresponding frequency band when the first switch 241 is coupled to the first switch branch 231 or the second switch branch 232.

[0219] The first frequency band is a transmitting frequency band in the satellite communication frequency band (for example, the transmitting frequency band in the Tiantong satellite system, 1980MHz-2010MHz), and the antenna 200 can transmit radio frequency signals to the communication satellite by coupling to the first directional pattern or the second directional pattern generated by the first switch branch 231 or the second switch branch 232 through the first connection point 211.

[0220] The second frequency band is a receiving frequency band in the satellite communication frequency band (for example, the receiving frequency band in the Tiantong satellite system, 2170MHz-2200MHz), and the antenna 200 can be coupled to the first directional pattern or the second directional pattern generated by the first switch branch 231 or the second switch branch 232 through the first connection point 211 to receive the radio frequency signal sent by the communication satellite.

[0221] When electronic device 10 uses antenna 200 to transmit and receive signals with a communication satellite in different time slots, antenna 200's operating frequency band can include the satellite system's transmit frequency band or receive frequency band in different time slots. In the corresponding time slots, antenna 200 can transmit radio frequency signals to the communication satellite or receive radio frequency signals sent by the communication satellite using the generated first or second radiation patterns.

[0222] Antenna 200 can have two directional patterns with different maximum radiation directions in the first frequency band. Antenna 200 can switch the first directional pattern and the second directional pattern generated by antenna 200 according to the communication conditions (for example, including relative positions) between the communication satellite and the electronic device 10 to switch the maximum radiation direction of the directional pattern generated by antenna 200 to ensure the communication quality between the communication satellite and the electronic device 10.

[0223] Therefore, the electronic device 10 has good communication characteristics within a range of relatively large angles (e.g., 50°, 60°, or 70°) relative to the top direction (the direction from the bottom of the electronic device to the top, such as the z-direction). For example, when a user is performing satellite communication, the antenna 200 has a wide beam characteristic, and the directional pattern generated by the antenna 200 has good characteristics within a relatively large angle, effectively improving the user experience.

[0224] At the same time, the first resonance / second resonance is generated by the line DM mode described in the above embodiment. Since the current generated by the line DM mode is mainly generated by the radiator 210, the current is mainly concentrated on the radiator 210. The current on the floor 300 has little effect on the antenna 200, and it is easy to determine the maximum radiation direction of the directional pattern generated by the antenna 200. In one embodiment, the two ends of the radiator 210 are open ends, and the radiator 210 can operate in a half-wavelength mode. The electrical length of the radiator 210 is half of the first wavelength, and the first wavelength is the wavelength corresponding to the resonance generated by the radiator 210. Among them, the wavelength corresponding to the resonance can be understood as the wavelength corresponding to the resonance point of the resonance, or the wavelength corresponding to the center frequency of the resonance frequency band. It should be understood that the above wavelengths are all vacuum wavelengths. Since there is a certain conversion relationship between the medium wavelength and the vacuum wavelength, the above vacuum wavelength can also be converted into the medium wavelength.

[0225] Furthermore, the linear CM mode can excite the transverse modes of the floor (which account for more than the longitudinal modes), but the currents corresponding to the transverse modes in the floor cancel each other out. Therefore, the system efficiency and radiation efficiency of the linear CM mode are low. In contrast, the linear DM mode, where the antenna radiation is primarily generated by the radiator, has better system efficiency and radiation efficiency than the linear CM mode.

[0226] In one embodiment, an angle between the first direction and the second direction is greater than or equal to 10° and less than or equal to 90°.

[0227] It should be understood that when the maximum radiation direction of the first radiation pattern and the maximum radiation direction of the second radiation pattern are offset toward both sides of the top direction (there is a larger angle between the first direction and the second direction), the width of the radiation beam of the antenna 200 can be further widened, so that the antenna 200 has good communication characteristics within a wider angle range (the angle with the top direction).

[0228] In one embodiment, the first switch branch 231 and the second switch branch 232 can be used to adjust current distribution on the radiator 210 and the floor 300 .

[0229] In one embodiment, the first switch branch 231 is coupled to the first connection point 211, the antenna 200 operates in the first frequency band or the second frequency band, and the current (e.g., current intensity, current density) on the floor 300 on the first side of the virtual axis is greater than the current on the floor 300 on the second side of the virtual axis, as shown in (a) and (b) in Figure 6.

[0230] In one embodiment, the first switch branch 231 is coupled to the first connection point 211, the antenna 200 operates in the first frequency band or the second frequency band, and the current (e.g., current intensity, current density) on the radiator 210 on the first side of the virtual axis is greater than the current on the radiator 210 on the second side of the virtual axis.

[0231] In one embodiment, the second switch branch 232 is coupled to the first connection point 211, the antenna 200 operates in the first frequency band or the second frequency band, and the current (e.g., current intensity, current density) on the floor 300 on the first side of the virtual axis is less than the current on the floor 300 on the second side of the virtual axis, as shown in (c) and (d) in Figure 6.

[0232] In one embodiment, the second switch branch 232 is coupled to the first connection point 211, the antenna 200 operates in the first frequency band or the second frequency band, and the current (e.g., current intensity, current density) on the radiator 210 on the first side of the virtual axis is less than the current on the radiator 210 on the second side of the virtual axis.

[0233] It should be understood that the current on the floor 300 described in the embodiment of the present application can be understood as the current near the edge of the floor 300 close to the radiator / parasitic branch, for example, the current within 30 mm from the edge.

[0234] It should be understood that when the current (e.g., current intensity, current density) on the floor 300 on the first side of the virtual axis is greater than the current on the floor 300 on the second side of the virtual axis, the directional pattern generated by the antenna 200 deflects toward the second side. When the current (e.g., current intensity, current density) on the floor 300 on the first side of the virtual axis is less than the current on the floor 300 on the second side of the virtual axis, the directional pattern generated by the antenna 200 deflects toward the first side. A larger angle between the first direction and the second direction can further broaden the width of the antenna radiation beam, enabling the antenna 200 to exhibit good communication characteristics over a wider range of angles (angles relative to the top direction).

[0235] Therefore, the first connection point 211 is coupled to different switch branches through the first switch 241 , so that the current distribution on the floor 300 can be adjusted, thereby deflecting the maximum radiation direction of the directional pattern generated by the antenna 200 .

[0236] In one embodiment, the first connection point 211 is located on a first side of the virtual axis, and the feeding point 221 is located on a second side of the virtual axis.

[0237] In one embodiment, the first switch branch 231 and the second switch branch 232 may both be capacitive, and the equivalent capacitance value of the first switch branch 231 and the equivalent capacitance value of the second switch branch 232 may both be less than or equal to 2 pF.

[0238] It should be understood that when the first switch branch 231 and the second switch branch 232 are capacitive, the equivalent capacitance value of the first switch branch 231 is smaller than the equivalent capacitance value of the second switch branch 232 .

[0239] When the second switch branch 232 is coupled to the first connection point 211 , the current on the floor 300 on the first side of the virtual axis is weakened, and the current on the floor 300 on the second side of the virtual axis is strengthened, compared to when the first switch branch 231 is coupled to the first connection point 211 .

[0240] When the first switch branch 231 is coupled to the first connection point 211 , the current on the floor 300 on the first side of the virtual axis increases, and the current on the floor 300 on the second side of the virtual axis decreases, compared to when the second switch branch 232 is coupled to the first connection point 211 .

[0241] In one embodiment, the first switch branch 231 and the second switch branch 232 may both be inductive. The equivalent inductance of the first switch branch 231 and the equivalent inductance of the second switch branch 232 may both be greater than or equal to 5 nH and less than or equal to 100 nH.

[0242] It should be understood that when the first switch branch 231 and the second switch branch 232 are inductive, the equivalent inductance of the first switch branch 231 is smaller than the equivalent inductance of the second switch branch 232 .

[0243] When the second switch branch 232 is coupled to the first connection point 211 , the current on the floor 300 on the first side of the virtual axis is weakened, and the current on the floor 300 on the second side of the virtual axis is strengthened, compared to when the first switch branch 231 is coupled to the first connection point 211 .

[0244] When the first switch branch 231 is coupled to the first connection point 211 , the current on the floor 300 on the first side of the virtual axis increases, and the current on the floor 300 on the second side of the virtual axis decreases, compared to when the second switch branch 232 is coupled to the first connection point 211 .

[0245] In one embodiment, the first switch branch 231 may be capacitive, and the second switch branch 232 may be inductive.

[0246] When the second switch branch 232 is coupled to the first connection point 211 , the current on the floor 300 on the first side of the virtual axis is weakened, and the current on the floor 300 on the second side of the virtual axis is strengthened, compared to when the first switch branch 231 is coupled to the first connection point 211 .

[0247] When the first switch branch 231 is coupled to the first connection point 211 , the current on the floor 300 on the first side of the virtual axis increases, and the current on the floor 300 on the second side of the virtual axis decreases, compared to when the second switch branch 232 is coupled to the first connection point 211 .

[0248] It should be understood that for the sake of simplicity of discussion, in the embodiments of the present application, only the example of the first connection point 211 being located on the first side of the virtual axis and the feeding point 221 being located on the second side of the virtual axis is used for illustration. In actual production or application, the first connection point 211 may also be located on the second side of the virtual axis and the feeding point 221 may also be located on the first side of the virtual axis. Similarly, the same can be understood accordingly.

[0249] In one embodiment, the radiator 210 may further include a grounding point 222, as shown in FIG7 . The grounding point 222 is located between the first connection point 211 and the feeding point 221. The radiator 210 is coupled to the floor 300 at the grounding point 222.

[0250] It should be understood that when radiator 210 is coupled to floor 300 at ground point 222, first switch branch 231 can be coupled to first connection point 211, and radiator 210 is further configured to generate a third resonance. When second switch branch 232 is coupled to first connection point 211, radiator 210 is further configured to generate a fourth resonance. The third and fourth resonances are generated by the line CM mode described in the above embodiments. In one embodiment, at the resonance point of the third resonance or the resonance point of the fourth resonance, the current in radiator 210 reverses direction on both sides of ground point 222. In one embodiment, the resonance point frequency of the third resonance is lower than the resonance point frequency of the first resonance. The resonance point frequency of the fourth resonance is lower than the resonance point frequency of the second resonance.

[0251] Furthermore, since the radiator 210 is coupled to the floor 300 at the grounding point 222, the coupling amount between the floor 300 and the radiator 210 is increased, thereby making the current difference on the floor 300 greater when the first switch branch 231 or the second switch branch 232 is coupled to the first connection point 211, thereby making the difference between the first radiation pattern and the second radiation pattern greater (for example, the angle between the maximum radiation directions is increased), which can further widen the width of the radiation beam of the antenna 200, so that the antenna 200 has good communication characteristics within a wider angle range (angle with the top direction).

[0252] In one embodiment, when radiator 210 is coupled to floor 300 at ground point 222, both ends of radiator 210 are open, allowing radiator 210 to operate in half-wavelength mode. The electrical length of radiator 210 is half the second wavelength, where the first wavelength is the wavelength corresponding to the center frequency between the two resonant point frequencies generated by radiator 210. In one embodiment, the second wavelength is greater than the first wavelength.

[0253] In one embodiment, the grounding point 222 may be located in the central area of ​​the radiator 210 , where the central area may be understood as an area within 5 mm from the center of the radiator 210 .

[0254] It should be understood that by increasing the structural symmetry of the antenna 200 , the antenna 200 can have better communication performance.

[0255] In one embodiment, grounding can be achieved through a grounding member at the grounding point 222. The width of the connection between the grounding member and the frame 11 is greater than or equal to 1 mm and less than or equal to 20 mm.

[0256] In one embodiment, when the first switching branch 231 is coupled to the first connection point 211, a first frequency difference between the resonant point frequency of the first resonance and the resonant point frequency of the third resonance is less than a first threshold. When the second switching branch 232 is coupled to the first connection point 211, a second frequency difference between the resonant point frequency of the second resonance and the resonant point frequency of the fourth resonance is greater than a first threshold. In one embodiment, the first threshold is 300 MHz. In one embodiment, the first threshold is 250 MHz. In one embodiment, the first threshold is 200 MHz. In one embodiment, the first threshold is 150 MHz.

[0257] It should be understood that when radiator 210 is coupled to floor 300 at ground point 222 and radiator 210 is coupled to different switch branches at first connection point 211, a third resonance and a fourth resonance can be generated by the line CM mode. The first switch branch 231 and the second switch branch 232 can also be used to adjust the frequency difference between the resonance point frequency of the line CM mode and the resonance point frequency of the line DM mode.

[0258] When the second switching branch 232 is coupled to the first connection point 211, the frequency difference between the resonance point frequency of the line CM mode and the resonance point frequency of the line DM mode increases compared to when the first switching branch 231 is coupled to the first connection point 211. This reduces the current in the floor 300 on the first side of the virtual axis, while increasing the current in the floor 300 on the second side of the virtual axis. When the first switching branch 231 is coupled to the first connection point 211, the frequency difference between the resonance point frequency of the line CM mode and the resonance point frequency of the line DM mode decreases compared to when the second switching branch 232 is coupled to the first connection point 211. This reduces the current in the floor 300 on the first side of the virtual axis, while decreasing the current in the floor 300 on the second side of the virtual axis.

[0259] In one embodiment, the first frequency difference is smaller than the second frequency difference, and the difference between the first frequency difference and the second frequency difference is greater than or equal to 100 MHz.

[0260] It should be understood that when the difference between the first frequency difference and the second frequency difference is within the aforementioned range, and the first connection point 211 is coupled to the first switch branch 231 or the second switch branch 232, respectively, the difference between the current on the floor 300 on the first side of the virtual axis and the current on the floor 300 on the second side of the virtual axis is greater, thereby increasing the difference between the first and second radiation patterns (e.g., the angle between the maximum radiation directions increases), further widening the width of the radiation beam of the antenna 200. The wide beamwidth of the antenna 200 enables the antenna 200 to have good communication characteristics over a wider range of angles (angles relative to the top direction).

[0261] In one embodiment, the distance between the feed point 221 and the adjacent end of the radiator 210 (e.g., the second position 202) (the length of the radiator 210) is less than or equal to one-third of the length of the radiator 210. In one embodiment, the distance between the feed point 221 and the adjacent end of the radiator 210 is less than or equal to 5 mm.

[0262] In one embodiment, the distance between the first connection point 211 and the adjacent end of the radiator 210 (e.g., the first position 201) (the length of the radiator 210) is less than or equal to one-third of the length of the radiator 210. In one embodiment, the distance between the first connection point 211 and the adjacent end of the radiator 210 is less than or equal to 5 mm.

[0263] It should be understood that moving the feeding point 221 toward one end of the radiator 210 facilitates miniaturization of the radiator 210. Moving the first connection point 211 toward one end of the radiator 210 facilitates adjustment of current distribution on the floor 300, thereby providing a wider current adjustment range.

[0264] Figures 8 to 10 show simulation results for antenna 200 in electronic device 10 shown in Figure 7 . Figure 8 shows the S-parameters of antenna 200 (with first switch branch 231 coupled to first connection point 211). Figure 9 shows the S-parameters of antenna 200 (with second switch branch 232 coupled to first connection point 211). Figure 10 shows the simulation results for the radiation efficiency of antenna 200 (with first switch branch 231 and second switch branch 232 coupled to first connection point 211).

[0265] As shown in FIG8 , the first switch branch 231 is coupled to the first connection point 211, and the antenna can resonate near 2.3 GHz and near 2.1 GHz. The resonance near 2.3 GHz may correspond to the first resonance in the above embodiment, and the resonance near 2.1 GHz may correspond to the third resonance in the above embodiment.

[0266] As shown in FIG9 , the second switch branch 232 is coupled to the first connection point 211, and the antenna can resonate near 2.2 GHz and near 1.8 GHz. The resonance near 2.2 GHz may correspond to the second resonance in the above embodiment, and the resonance near 1.8 GHz may correspond to the fourth resonance in the above embodiment.

[0267] As shown in FIG10 , in the first frequency band (eg, 2170 MHz-2200 MHz), the antennas in which the first switch branch 231 is coupled to the first connection point 211 or the second switch branch 232 is coupled to the first connection point 211 both have good radiation efficiency.

[0268] Figures 11 to 15 are directional patterns of the antenna 200 in the electronic device 10 shown in Figure 7 at 2.2 GHz. Figure 11 is a two-dimensional directional pattern generated by the antenna 200 (the first switch branch 231 is coupled to the first connection point 211). Figure 12 is a three-dimensional directional pattern generated by the antenna 200 (the first switch branch 231 is coupled to the first connection point 211). Figure 13 is a two-dimensional directional pattern generated by the antenna 200 (the second switch branch 232 is coupled to the first connection point 211). Figure 14 is a three-dimensional directional pattern generated by the antenna 200 (the second switch branch 232 is coupled to the first connection point 211). Figure 15 is a directional pattern formed by the superposition of the first directional pattern and the second directional pattern.

[0269] It should be understood that in the directional diagram shown in the embodiment of the present application, the vertical axis is the angle Theta (θ) (the angle with the z-axis) with the z-direction (the top direction, the direction from the bottom of the electronic device to the top), and the horizontal axis is the angle Phi with the x-direction (the extension direction of the first side). (Angle with the x-axis in the xoy plane).

[0270] It should be understood that the first connection point 211 is coupled to the first switch branch 231, and the antenna 200 can generate the first directional pattern in the above embodiment. The first connection point 211 is coupled to the second switch branch 232, and the antenna 200 can generate the second directional pattern in the above embodiment.

[0271] As shown in FIG11 and FIG13 , the first and second directional patterns generated by the antenna have gains greater than or equal to 0 dBi within a range where Theta (θ) is less than 25°, and the antenna has good radiation characteristics.

[0272] The first switch branch is coupled to the first connection point, and the first directional pattern is only at Phi In the range greater than 90° and less than 270°, the gain is greater than or equal to 0 dBi, as shown in Figure 11.

[0273] The first switch branch is coupled to the first connection point, and the current (for example, current intensity, current density) on the floor on the first side of the virtual axis (for example, the first connection point is located on the first side of the virtual axis, and the feeding point is located on the second side of the virtual axis) is greater than the current on the floor on the second side of the virtual axis, and the first radiation pattern generated by the antenna is deflected toward the second side (for example, the feeding point side), as shown in Figure 12.

[0274] The second switch branch is coupled to the first connection point, and the second directional pattern is only at Phi In the range of greater than 0° and less than 90° and greater than 270° and less than 360°, the gain is greater than or equal to 0 dBi, as shown in Figure 13.

[0275] The first switch branch is coupled to the second connection point, and the current (for example, current intensity, current density) on the floor on the first side of the virtual axis (for example, the first connection point is located on the first side of the virtual axis, and the feeding point is located on the second side of the virtual axis) is smaller than the current on the floor on the second side of the virtual axis. The first radiation pattern generated by the antenna is deflected toward the first side (for example, the side of the first connection point), as shown in FIG14 .

[0276] When the first and second patterns are superimposed (synthesized), the antenna exhibits good radiation characteristics within a range where Theta (θ) is less than 70°, as shown in Figure 15. When the communications satellite moves within this angular range (within 70° of the top direction), it remains within the region of electronic device 10 where the antenna exhibits good radiation characteristics, ensuring good communication between the communications satellite and electronic device 10.

[0277] FIG16 is a schematic diagram of another electronic device 10 provided in an embodiment of the present application.

[0278] As shown in FIG16 , the first side 131 or the second side 132 further includes a third position 203, and the second side 132 further includes a fourth position 204. The frame 11 may have an insulating gap at the third position 203, or may be grounded at the third position 203. The frame 11 may have an insulating gap at the fourth position 204, or may be grounded at the fourth position 204.

[0279] It should be understood that the first side 131 in the embodiment of the present application may include a straight-line extending side and may also include an arc-shaped extending side, and the second side 132 may be understood similarly. When the outer contour of the electronic device includes an arc-shaped chamfer, the first side 131 may include its straight-line extending portion and half of the arc-shaped extending portion, and the second side 132 may include its straight-line extending portion and the other half of the arc-shaped extending portion. The extension direction of the first side 131 is the direction of its straight-line extending portion. The extension direction of the second side 132 is the direction of its straight-line extending portion. The third side 133 in subsequent embodiments may also be understood accordingly.

[0280] The antenna 200 may further include a first parasitic stub 251 , a third switch branch 233 , a fourth switch branch 234 , and a second switch 242 .

[0281] The first parasitic branch 251 includes a conductive portion of the frame 11 between the third position 203 and the fourth position 204. At least a portion of the first parasitic branch 251 is spaced apart from the floor 300.

[0282] The first parasitic branch 251 includes a second connection point 212. A third switch branch 233, a fourth switch branch 234, and a second switch 242 are coupled between the second connection point 212 and the floor 300. A first connection port of the second switch 242 is coupled to the third switch branch 233. A second connection port of the second switch 242 is coupled to the fourth switch branch 234. For ease of understanding, the third switch branch 233 and the fourth switch branch 234 can be considered to be connected in parallel.

[0283] It should be understood that the antenna 200 shown in FIG16 differs from the antenna 200 shown in FIG7 only in the first parasitic stub 251. In the antenna 200 shown in FIG7 , the first parasitic stub 251 is not provided. In the antenna 200 shown in FIG16 , however, the conductive portion between the third position 203 and the fourth position 204 serves as the first parasitic stub 251.

[0284] It should be understood that the parasitic branch 251 is set, or the parasitic branch 251 is not set, or multiple parasitic branches are set as will be described in subsequent embodiments, the devices set in the first switch branch 231 can be the same or different, the equivalent device values ​​of the first switch branch 231 can be the same or different, and the specific form of the first switch branch 231 can be selected according to the target directional pattern; similarly, one or more parasitic branches can be set, and the specific form of the second switch branch 232 can also be selected according to the target directional pattern.

[0285] In one embodiment, the first connection point 211 is coupled to the first switch branch 231, and the second connection point 212 is coupled to the third switch branch 233 via the second switch 242. For example, the common port of the second switch 242 is coupled to the first connection port of the second switch 242, and the third switch branch 233 is coupled to the second connection point 212. The antenna 200 generates a first radiation pattern. In one embodiment, the generation of the first radiation pattern by the antenna 200 can be considered to be the generation of the first radiation pattern by the radiator 210 and the first parasitic branch 251.

[0286] In one embodiment, first connection point 211 is coupled to second switch branch 232, and second connection point 212 is coupled to fourth switch branch 234 via second switch 242. For example, the common port of second switch 242 is coupled to the second connection port of second switch 242, and fourth switch branch 234 is coupled to second connection point 212, thereby generating a second directional pattern for antenna 200. In one embodiment, the generation of the second directional pattern by antenna 200 can be considered to be the result of radiator 210 and first parasitic stub 251 being used to generate the second directional pattern for antenna 200.

[0287] It should be understood that each of the first switch branch 231 , the second switch branch 232 , the third switch branch 233 and the fourth switch branch 234 may include one of the following three situations:

[0288] 1. One or more electronic devices are used to connect the radiator / parasitic branch to the ground at the corresponding connection point through the electronic device;

[0289] 2. Excluding electronic devices, used to ensure that the radiator / parasitic branch is grounded at the corresponding connection point without passing through any electronic devices;

[0290] 3. It does not include electronic devices and is separated from the floor, and is used to separate the radiator / parasitic branch from the floor at the corresponding connection point;

[0291] It should be understood that in the embodiment shown in FIG16 , at least one of the radiator 210 and the first parasitic stub 251, through corresponding components within the switch branch disposed thereon, causes the antenna 200 to generate a first pattern; and at least the other of the radiator 210 and the first parasitic stub 251, through corresponding components within the switch branch disposed thereon, causes the antenna 200 to generate a second pattern. Therefore, "antenna 200 generating the first pattern" can be understood as "radiator 210, first parasitic stub 251, first switch branch 231, and third switch branch 233 are used to generate the first pattern of antenna 200," and "antenna 200 generating the second pattern" can be understood as "radiator 210, first parasitic stub 251, second switch branch 232, and fourth switch branch 234 are used to generate the second pattern of antenna 200." A similar understanding can be applied to other embodiments of the present application.

[0292] In one embodiment, the fourth switch branch 234 can be used to prevent the first parasitic stub 251 from affecting the second directivity pattern.

[0293] In one embodiment, the fourth switch branch 234 may not include any electronic components and may directly electrically connect the second connection point 212 to the floor 300. When the first connection point 211 is coupled to the second switch branch 232, the second connection point 212 is coupled to the fourth switch branch 234 via the second switch 242, and the floor 300 is coupled to the second connection point 212, this is equivalent to not having the first parasitic stub 251. In one embodiment, the fourth switch branch 234 may include electronic components that can distance the parasitic resonance generated by the first parasitic stub 251 from the resonance generated by the radiator 210 (e.g., with a frequency difference greater than or equal to 300 MHz).

[0294] Among them, the first parasitic branch 251 does not affect the second directional pattern in various ways (for example, the second connection point 212 is coupled with the floor 300 branch). It can also be understood that the first parasitic branch 251 is used to generate the second directional pattern together with the radiator 210. This is because when the first parasitic branch 251 is switched to couple other switch branches, the second directional pattern will change accordingly.

[0295] It should be understood that the first parasitic branch 251 can be used to increase the difference between the first and second directional patterns (for example, increasing the angle between the maximum radiation directions, for example, the angle between the first and second directions is greater than or equal to 15°), further widening the width of the radiation beam of the antenna 200, and enabling the antenna 200 to have good communication characteristics over a wider range of angles (angles relative to the top direction). It should be understood that the greater difference between the first and second directional patterns mentioned in this application can be understood as a stronger complementarity between the first and second directional patterns.

[0296] It should be understood that in the embodiments of the present application (for example, the electronic device 10 shown in FIG16 ), the antenna 200 is described as being in the same operating state. The same operating state can be understood as meaning that the operating frequency band of the antenna 200 may include the first frequency band, and the antenna 200 can communicate in the first frequency band when the first switch 241 is coupled to the first switch branch 231 or the second switch branch 232, and when the second switch 242 is coupled to the third switch branch 233 or the fourth switch branch 234.

[0297] In one embodiment, the first connection point 211 is coupled to the first switch branch 231, and the second connection point 212 is coupled to the third switch branch 233 via the second switch 242. When the antenna 200 operates in the first frequency band or the second frequency band, the current on the floor 300 on the first side of the virtual axis is greater than the current on the floor 300 on the second side of the virtual axis, and the first parasitic branch 251 is located on the second side of the virtual axis.

[0298] It should be understood that the first parasitic branch 251 can be used to adjust the angle between the maximum radiation direction of the first radiation pattern and the top direction, making the angle larger (the maximum radiation direction is deflected toward the side of the first parasitic branch 251), and the antenna 200 has better radiation characteristics within a wider angle range.

[0299] In one embodiment, the first connection point 211 is located on a first side of the virtual axis, and the feed point 221 is located on a second side of the virtual axis. The first connection point 211 is coupled to the first switch branch 231, and the current on the floor 300 on the first side of the virtual axis is greater than the current on the floor 300 on the second side of the virtual axis, if one of the following conditions is met:

[0300] 1. The first switch branch 231 and the second switch branch 232 can both be capacitive. The equivalent capacitance of the first switch branch 231 and the equivalent capacitance of the second switch branch 232 can both be less than or equal to 2 pF. The equivalent capacitance of the first switch branch 231 is less than the equivalent capacitance of the second switch branch 232.

[0301] 2. The first switch branch 231 and the second switch branch 232 can both be inductive. The equivalent inductance of the first switch branch 231 and the equivalent inductance of the second switch branch 232 can both be greater than or equal to 5 nH and less than or equal to 100 nH. The equivalent inductance of the first switch branch 231 is smaller than the equivalent inductance of the second switch branch 232.

[0302] 3. The first switch branch 231 may be capacitive, and the second switch branch 232 may be inductive.

[0303] It should be understood that, for the sake of simplicity of discussion, in the embodiments of the present application, only the first connection point 211 is located on the first side of the virtual axis and the feeding point 221 is located on the second side of the virtual axis for illustration. In actual production or application, the positions of the first connection point 211 and the feeding point 221 can be adjusted. For example, the first connection point 211 is located on the second side of the virtual axis, and the feeding point 221 is located on the first side of the virtual axis. It is only necessary to adjust the first switch branch 231 and the second switch branch 232 according to the above rules. When the first connection point 211 is coupled to the first switch branch 231, the current on the floor 300 on the first side of the virtual axis can be greater than the current on the floor 300 on the second side of the virtual axis.

[0304] In one embodiment, the first connection point 211 is coupled to the first switch branch 231, and the second connection point 212 is coupled to the third switch branch 233 through the second switch 242. When the antenna 200 operates in the first frequency band or the second frequency band, the current on the radiator 210 and the current on the first parasitic branch 251 are in the same direction (the current path is clockwise or counterclockwise).

[0305] In one embodiment, the first parasitic branch 251 can be of any structure, and the embodiments of the present application do not limit this. In one embodiment, the frame 11 can have an insulating gap at the third position 203 and the fourth position 204, and the first parasitic branch 251 can be an antenna structure similar to a dipole. In one embodiment, the frame 11 can have an insulating gap between the third position 203 and the fourth position 204, and the first parasitic branch 251 can be an antenna structure composed of multiple branches. For the sake of simplicity of discussion, in the embodiments of the present application, only one end of the first parasitic branch 251 is described as an open end and the other end is a grounded end. The frame 11 is coupled to the floor 300 at the third position 203 and a third insulating gap is opened at the fourth position 204, as shown in Figure 17.

[0306] In one embodiment, the third position 203 is located between the fourth position 204 and the second position 202. The first position 201, the second position 202, the third position 203 and the fourth position 204 are arranged on the frame 11 in sequence.

[0307] It should be understood that, for the sake of simplicity of discussion, in the embodiments of the present application, only the above-mentioned structure is used as an example for illustration. In actual production or design, the fourth position 204 may also be located between the third position 203 and the second position 202. The embodiments of the present application do not limit this and will not be described one by one.

[0308] In one embodiment, the first connection point 211 is coupled to the first switch branch 231, the second connection point 212 is coupled to the third switch branch 233 through the second switch 242, the feed circuit 220 feeds an electrical signal, the radiator 210 is used to generate a first main resonance, the first parasitic branch 251 is used to generate a first parasitic resonance, and the first main resonance and the first parasitic resonance together form the above-mentioned first resonance (because the frequency difference between the resonance point of the first parasitic resonance and the resonance point of the first main resonance is small, in the S-parameter diagram, the first main resonance and the first parasitic resonance are merged into one resonance). In one embodiment, the resonance point of the first parasitic resonance is located within the resonance frequency band of the first main resonance. In one embodiment, the frequency difference between the resonance point frequency of the first parasitic resonance and the resonance point frequency of the first main resonance is less than or equal to 100 MHz. In one embodiment, the frequency difference between the resonance point frequency of the first parasitic resonance and the resonance point frequency of the first main resonance is less than or equal to 50 MHz. In one embodiment, the resonance point frequency of the first parasitic resonance can be less than the resonance point frequency of the first main resonance.

[0309] At the same time, in an embodiment of the present application, the coupling between the radiator 210 and the first parasitic branch 251 is weak, and the first parasitic resonance cannot be well excited. Therefore, the pit corresponding to the first parasitic resonance does not appear clearly in the S-parameter diagram. However, since the first parasitic resonance is partially excited by current, an obvious pit will appear in the efficiency curve (for example, radiation efficiency or system efficiency). For example, if an efficiency pit appears at the first frequency point, the first frequency point can be considered to correspond to the resonance point of the above-mentioned first parasitic resonance. In one embodiment, the efficiency (for example, radiation efficiency or system efficiency) caused by the pit does not exceed 1.5dB. In one embodiment, the efficiency (for example, radiation efficiency or system efficiency) caused by the pit does not exceed 1dB.

[0310] In one embodiment, the first parasitic stub 251 has one open end and the other grounded end, and can operate in a quarter-wavelength mode. The electrical length of the first parasitic stub 251 is one-quarter of the third wavelength, where the third wavelength is the wavelength corresponding to the parasitic resonance generated by the first parasitic stub 251. In one embodiment, the third wavelength is greater than the first wavelength.

[0311] In one embodiment, the distance between the first parasitic stub 251 and the radiator 210 in the third direction is less than half the length of the second side 132. The third direction is the extension direction of the second side 132, for example, the top direction (z direction).

[0312] It should be understood that the first parasitic stub 251 may be located at a side of the midpoint of the second side 132 close to the first side 131 , so that the first parasitic stub 251 can be better excited and the antenna 200 has better radiation characteristics.

[0313] In one embodiment, the conductor portion between the third position 203 and the second position 202 may also serve as a parasitic stub, as shown in FIG18 .

[0314] It should be understood that the parasitic stub (formed by the conductor portion between the third position 203 and the second position 202) is used to improve the radiation characteristics (e.g., improve efficiency) of the antenna 200. The parasitic stub can also be used to increase the coupling between the first parasitic stub 251 and the radiator 210 to better excite the first parasitic stub 251. The parasitic stub can also be used to reduce the voltage of the second switch 242 to prevent the second switch 242 from breaking down due to excessive voltage.

[0315] For the sake of simplicity, the parts of the antenna 200 shown in Figures 17 and 18 that are similar to the antenna 200 shown in Figure 7 are not repeated one by one. For example, the similar parts include: the position of the radiator 210, the frequency band of satellite communication; the resonance generated by the coupling of the radiator 210 with the first switch branch 231 or the second switch branch 232 at the first connection point 211; the current distribution of the floor 300 coupled with the first switch branch 231 or the second switch branch 232 at the first connection point 211; the value range of the equivalent device of the first switch branch 231 and the second switch branch 232; the position of the feeding point 221; the position of the grounding point 222; the position of the first connection point 211; and so on.

[0316] FIG19 is a schematic diagram of another electronic device 10 provided in an embodiment of the present application.

[0317] 19 , the frame 11 further includes a third side 133 intersecting the first side 131 at an angle. The first side 131 or the third side 133 further includes a fifth position 205 , and the third side 133 further includes a sixth position 206 .

[0318] The antenna 200 may further include a second parasitic stub 252 , a fifth switch branch 235 , a sixth switch branch 236 , and a third switch 243 .

[0319] The second parasitic branch 252 includes a conductive portion of the frame 11 between the fifth position 205 and the sixth position 206. At least a portion of the second parasitic branch 252 is spaced apart from the floor 300.

[0320] Second parasitic branch 252 includes third connection point 213. Fifth switch branch 235, sixth switch branch 236, and third switch 243 are coupled between third connection point 213 and floor 300. A first connection port of third switch 243 is coupled to fifth switch branch 235. A second connection port of third switch 243 is coupled to sixth switch branch 236. For ease of understanding, third switch branch 233 and fourth switch branch 234 can be considered to be connected in parallel.

[0321] It should be understood that the antenna 200 shown in FIG19 differs from the antenna 200 shown in FIG16 only in the second parasitic stub 252. The antenna 200 shown in FIG17 does not include the second parasitic stub 252, but only includes the first parasitic stub 251. However, the antenna 200 shown in FIG19 includes both the first parasitic stub 251 and the second parasitic stub 252.

[0322] It should be understood that whether the second parasitic branch 252 is provided or not, the components provided in the first switch branch 231 can be the same or different, the equivalent component values ​​of the first switch branch 231 can be the same or different, and the specific form of the first switch branch 231 can be selected based on the target radiation pattern. Similarly, whether the second parasitic branch 252 is provided or not, the specific form of the second switch branch 232, the third switch branch 233, or the fourth switch branch 234 can also be selected based on the target radiation pattern. In the antenna 200 shown in Figure 19, the first connection point 211 is coupled to the first switch branch 231, the second connection point 212 is coupled to the third switch branch 233, and the third connection point 213 is coupled to the sixth switch branch 236 via the third switch 243. For example, the common port of the third switch 243 is coupled to the second connection port of the third switch 243. The first switch branch 231 is coupled to the first connection point 211, the third switch branch 233 is coupled to the second connection point 212, and the third connection point 213 is coupled to the sixth switch branch 236, so that the antenna 200 generates a first directional pattern. In one embodiment, the generation of the first directional pattern by the antenna 200 can be considered to be the result of the radiator 210, the first parasitic stub 251, the second parasitic stub 251, the first switch branch 231, the third switch branch 233, and the sixth switch branch 236 being used to generate the first directional pattern of the antenna 200.

[0323] First connection point 211 is coupled to second switch branch 232, second connection point 212 is coupled to fourth switch branch 234, and third connection point 213 is coupled to fifth switch branch 235 via third switch 243. For example, the common port of third switch 243 is coupled to the first connection port of third switch 243. Antenna 200 generates a second radiation pattern. In one embodiment, the second radiation pattern generated by antenna 200 can be considered to be generated by radiator 210, first parasitic stub 251, second parasitic stub 252, second switch branch 232, fourth switch branch 234, and fifth switch branch 235.

[0324] It should be understood that each of the fifth switch branch 235 and the sixth switch branch 236 may also include one of the following three situations:

[0325] 1. One or more electronic devices are used to connect the radiator / parasitic branch to the ground at the corresponding connection point through the electronic device;

[0326] 2. Excluding electronic devices, used to ensure that the radiator / parasitic branch is grounded at the corresponding connection point without passing through any electronic devices;

[0327] 3. It does not include electronic devices and is separated from the floor, and is used to separate the radiator / parasitic branch from the floor at the corresponding connection point;

[0328] It should be understood that in the embodiment shown in Figure 19, at least two of the radiator 210, the first parasitic branch 251 and the second parasitic branch 252, through corresponding components in the switch branch set thereon, enable the antenna 200 to generate a first radiation pattern; at least another two of the radiator 210, the first parasitic branch 251 and the second parasitic branch 252 (for example, different from the two used to generate the first radiation pattern) through corresponding components in the switch branch set thereon, enable the antenna 200 to generate a second radiation pattern. Therefore, “antenna 200 generates a first directivity pattern” can be understood as “radiator 210, first parasitic branch 251, second parasitic branch 252, first switch branch 231, third switch branch 233, and sixth switch branch 236 are used to generate the first directivity pattern of antenna 200”; and “antenna 200 generates a second directivity pattern” can be understood as “radiator 210, first parasitic branch 251, second parasitic branch 252, second switch branch 232, fourth switch branch 234, and fifth switch branch 235 are used to generate the second directivity pattern of antenna 200”. The same can be said for other embodiments in this application.

[0329] In one embodiment, the sixth switch branch 236 can be used to prevent the second parasitic stub 252 from affecting the first pattern. In one embodiment, the sixth switch branch 236 may not include electronic components and can directly electrically connect the third connection point 213 to the floor 300. The third connection point 213 is coupled to the sixth switch branch 236 via the third switch 243, and the third connection point 213 is coupled to the floor 300, which is equivalent to not having the second parasitic stub 252. In one embodiment, the sixth switch branch 236 can include electronic components that can distance the parasitic resonance generated by the second parasitic stub 252 from the resonance generated by the radiator 210 (e.g., with a frequency difference greater than or equal to 300 MHz).

[0330] Among them, the second parasitic branch 252 does not affect the first directional pattern in various ways (for example, the third connection point 213 is coupled with the floor 300 branch). It can also be understood that the second parasitic branch 252 is used to generate the second directional pattern together with the radiator 210 and the first parasitic branch 251. This is because when the second parasitic branch 252 is switched to couple other switch branches, the second directional pattern will change accordingly.

[0331] In one embodiment, the fourth switch branch 234 can be used to prevent the first parasitic stub 251 from affecting the second pattern. In one embodiment, the fourth switch branch 234 may not include electronic components and can directly electrically connect the second connection point 212 to the floor 300. When the first connection point 211 is coupled to the second switch branch 232, the second connection point 212 is coupled to the fourth switch branch 234 via the second switch 242, and the floor 300 is coupled to the second connection point 212, this is equivalent to not having the first parasitic stub 251. In one embodiment, the fourth switch branch 234 can include electronic components that can distance the parasitic resonance generated by the first parasitic stub 251 from the resonance generated by the radiator 210 (e.g., with a frequency difference greater than or equal to 300 MHz).

[0332] Among them, the first parasitic branch 251 does not affect the second direction pattern in various ways (for example, the second connection point 212 is coupled with the floor 300 branch). It can also be understood that the first parasitic branch 251 is used to generate the second direction pattern together with the radiator 210 and the second parasitic branch 252.

[0333] It should be understood that the first parasitic branch 251 and the second parasitic branch 252 can be used to make the difference between the first radiation pattern and the second radiation pattern larger (for example, the angle between the maximum radiation directions is increased, for example, the angle between the first direction and the second direction is greater than or equal to 20°), which can further widen the width of the radiation beam of the antenna 200, so that the antenna 200 has good communication characteristics within a wider angle range (angle with the top direction).

[0334] It should be understood that in the embodiments of the present application (for example, the electronic device 10 shown in FIG19 ), the antenna 200 is described as being in the same operating state. The same operating state can be understood as meaning that the operating frequency band of the antenna 200 may include the first frequency band, and the antenna 200 can communicate in the first frequency band when the first switch 241 is coupled to the first switch branch 231 or the second switch branch 232, the second switch 242 is coupled to the third switch branch 233 or the fourth switch branch 234, and the third switch 243 is coupled to the fifth switch branch 235 or the sixth switch branch 236.

[0335] In one embodiment, the first connection point 211 is coupled to the first switch branch 231, the second connection point 212 is coupled to the third switch branch 233, and the third connection point 213 is coupled to the sixth switch branch 236 via the third switch 243. When the antenna 200 operates in the first frequency band or the second frequency band, the current on the floor 300 on the first side of the virtual axis is greater than the current on the floor 300 on the second side of the virtual axis, the first parasitic branch 251 is located on the second side of the virtual axis, and the second parasitic branch 252 is located on the first side of the virtual axis.

[0336] In one embodiment, the first connection point 211 is coupled to the second switch branch 232, the second connection point 212 is coupled to the fourth switch branch 234, the third connection point 213 is coupled to the fifth switch branch 235 via the third switch 243, the antenna 200 operates in the first frequency band or the second frequency band, and the current on the floor 300 on the first side of the virtual axis is less than the current on the floor 300 on the second side of the virtual axis.

[0337] It should be understood that the first parasitic branch 251 can be used to adjust the angle between the maximum radiation direction of the first pattern and the top direction, making the angle larger (the maximum radiation direction is deflected toward the first parasitic branch 251). The second parasitic branch 252 can be used to adjust the angle between the maximum radiation direction of the second pattern and the top direction, making the angle larger (the maximum radiation direction is deflected toward the second parasitic branch 252). When the maximum radiation direction of the first pattern and the maximum radiation direction of the second pattern are offset toward the top direction, the bandwidth of the radiation beam can be widened, allowing the antenna 200 to have better radiation characteristics over a wider angle range.

[0338] In one embodiment, the first connection point 211 is located on a first side of the virtual axis, and the feeding point 221 is located on a second side of the virtual axis.

[0339] The first connection point 211 is coupled to the first switch branch 231, and the current on the floor 300 on the first side of the virtual axis is greater than the current on the floor 300 on the second side of the virtual axis. Alternatively, the first connection point 211 is coupled to the second switch branch 232, and the current on the floor 300 on the first side of the virtual axis is less than the current on the floor 300 on the second side of the virtual axis. One of the following conditions must be met:

[0340] 1. The first switch branch 231 and the second switch branch 232 can both be capacitive. The equivalent capacitance of the first switch branch 231 and the equivalent capacitance of the second switch branch 232 can both be less than or equal to 2 pF. The equivalent capacitance of the first switch branch 231 is less than the equivalent capacitance of the second switch branch 232.

[0341] 2. The first switch branch 231 and the second switch branch 232 can both be inductive. The equivalent inductance of the first switch branch 231 and the equivalent inductance of the second switch branch 232 can both be greater than or equal to 5 nH and less than or equal to 100 nH. The equivalent inductance of the first switch branch 231 is smaller than the equivalent inductance of the second switch branch 232.

[0342] 3. The first switch branch 231 may be capacitive, and the second switch branch 232 may be inductive.

[0343] It should be understood that, for the sake of simplicity, in the embodiments of the present application, only the first connection point 211 is located on the first side of the virtual axis and the feeding point 221 is located on the second side of the virtual axis for illustration. In actual production or application, the positions of the first connection point 211 and the feeding point 221 can be adjusted. For example, the first connection point 211 is located on the second side of the virtual axis, and the feeding point 221 is located on the first side of the virtual axis. It is only necessary to adjust the first switch branch 231 and the second switch branch 232 according to the above rules. When the first connection point 211 is coupled with the first switch branch 231, the current on the floor 300 on the first side of the virtual axis can be greater than the current on the floor 300 on the second side of the virtual axis. Alternatively, when the first connection point 211 is coupled with the second switch branch 232, the current on the floor 300 on the first side of the virtual axis can be less than the current on the floor 300 on the second side of the virtual axis.

[0344] In one embodiment, the first connection point 211 is coupled to the first switch branch 231, the second connection point 212 is coupled to the third switch branch 233, and the third connection point 213 is coupled to the sixth switch branch 236 through the third switch 243. When the antenna 200 operates in the first frequency band or the second frequency band, the current on the radiator 210 and the current on the first parasitic branch 251 are in the same direction (the current path is clockwise or counterclockwise).

[0345] In one embodiment, the first connection point 211 is coupled to the second switch branch 232, the second connection point 212 is coupled to the fourth switch branch 234, and the third connection point 213 is coupled to the fifth switch branch 235 through the third switch 243. When the antenna 200 operates in the first frequency band or the second frequency band, the current on the radiator 210 and the current on the second parasitic branch 252 are in the same direction (the current path is clockwise or counterclockwise).

[0346] It should be understood that when the current on the radiator 210 is in the same direction as the current on the parasitic branch (the first parasitic branch 251 or the second parasitic branch 252 ), the bandwidth of the radiation beam can be better broadened, so that the antenna 200 has better radiation characteristics in a wider angle range.

[0347] In one embodiment, the first parasitic branch 251 and the second parasitic branch 252 can be of any structure, and the embodiments of the present application do not limit this. In one embodiment, the frame 11 can have an insulating gap at the third position 203 and the fourth position 204, and / or an insulating gap at the fifth position 205 and the sixth position 206, and the first parasitic branch 251 and / or the second parasitic branch 252 can be a dipole-like antenna structure. In one embodiment, the frame 11 can have an insulating gap between the third position 203 and the fourth position 204, and / or an insulating gap between the fifth position 205 and the sixth position 206, and the first parasitic branch 251 and / or the second parasitic branch 252 can be an antenna structure composed of multiple branches. For the sake of simplicity of discussion, in the embodiments of the present application, only one end of the first parasitic branch 251 and the second parasitic branch 252 is open and the other end is grounded for description. The frame 11 is coupled to the floor 300 at the third position 203 and has a third insulating gap at the fourth position 204. The frame 11 is coupled to the floor 300 at the third position 203 and has a fourth insulating gap at the sixth position 206, as shown in FIG20 .

[0348] In one embodiment, the third position 203 is located between the fourth position 204 and the second position 202. The fifth position 205 is located between the sixth position 206 and the first position 201.

[0349] It should be understood that for the sake of simplicity of discussion, in the embodiments of the present application, only the above-mentioned structure is used as an example for illustration. In actual production or design, the fourth position 204 may also be located between the third position 203 and the second position 202, and the sixth position 206 may be located between the fifth position 205 and the first position 201. The embodiments of the present application do not limit this and will not be described one by one.

[0350] In one embodiment, the first connection point 211 is coupled to the first switch branch 231, the second connection point 212 is coupled to the third switch branch 233, and the third connection point 213 is coupled to the sixth switch branch 236. An electrical signal is fed into the feed circuit 220, the radiator 210 is configured to generate a first main resonance, and the first parasitic stub 251 is configured to generate a first parasitic resonance. The first connection point 211 is coupled to the second switch branch 232, the second connection point 212 is coupled to the fourth switch branch 234, and the third connection point 213 is coupled to the fifth switch branch 235. An electrical signal is fed into the feed circuit 220, the radiator 210 is configured to generate a second main resonance, and the second parasitic stub 252 is configured to generate a second parasitic resonance.

[0351] The first main resonance and the first parasitic resonance together form the above-mentioned first resonance, and the second main resonance and the second parasitic resonance together form the above-mentioned second resonance (due to the small frequency difference between the resonance point of the parasitic resonance and the resonance point of the main resonance, in the S-parameter diagram, the main resonance and the parasitic resonance are merged into one resonance). In one embodiment, the resonance point of the parasitic resonance is located within the resonance frequency band of the main resonance. In one embodiment, the frequency difference between the resonance point frequency of the parasitic resonance and the resonance point frequency of the main resonance is less than or equal to 100 MHz. In one embodiment, the frequency difference between the resonance point frequency of the parasitic resonance and the resonance point frequency of the main resonance is less than or equal to 50 MHz. In one embodiment, the resonance point frequency of the parasitic resonance can be less than the resonance point frequency of the main resonance.

[0352] At the same time, in an embodiment of the present application, the coupling between the radiator 210 and the parasitic branch (the first parasitic branch 251 or the second parasitic branch 252) is weak, and the parasitic resonance cannot be well excited. Therefore, the pit corresponding to the parasitic resonance does not appear clearly in the S-parameter diagram. However, since the parasitic resonance is partially excited by current, an obvious pit will appear in the efficiency curve (for example, radiation efficiency or system efficiency). For example, if an efficiency pit appears at the first frequency point, the first frequency point can be considered to correspond to the resonance point of the above-mentioned first parasitic resonance or second resonance. In one embodiment, the efficiency (for example, radiation efficiency or system efficiency) caused by the pit does not exceed 1.5dB. In one embodiment, the efficiency (for example, radiation efficiency or system efficiency) caused by the pit does not exceed 1dB.

[0353] In one embodiment, the first parasitic stub 251 and the second parasitic stub 252 have one open end and the other end grounded. The first parasitic stub 251 and the second parasitic stub 252 can operate in a quarter-wavelength mode. The electrical length of the first parasitic stub 251 and the second parasitic stub 252 is half of a fourth wavelength, where the fourth wavelength corresponds to the parasitic resonance generated by the parasitic stub. In one embodiment, the fourth wavelength is greater than the first wavelength.

[0354] In one embodiment, the distance between the first parasitic stub 251 or the second parasitic stub 252 and the radiator 210 in the third direction is less than half the length of the second side 132 (or the third side 133). The third direction is the extending direction of the second side 132 (or the third side 133), for example, the top direction (z direction).

[0355] It should be understood that the first parasitic branch 251 can be located at the midpoint of the second side 132 on the side close to the first side 131, and the second parasitic branch 252 can be located at the midpoint of the third side 133 on the side close to the first side 131, so that the first parasitic branch 251 and the second parasitic branch 252 can be better excited, so that the antenna 200 has better radiation characteristics.

[0356] In one embodiment, the conductor portion between the third position 203 and the second position 202 and / or the conductor portion between the first position 201 and the fifth position 205 may also serve as a parasitic stub, as shown in FIG. 21 .

[0357] It should be understood that the parasitic stub (the parasitic stub formed by the conductor portion between the third position 203 and the second position 202 and / or the conductor portion between the first position 201 and the fifth position 205) is used to improve the radiation characteristics of the antenna 200 (e.g., improve efficiency). The parasitic stub can also be used to increase the coupling between the first parasitic stub 251 (and / or the second parasitic stub 252) and the radiator 210 to better stimulate the first parasitic stub 251 (and / or the second parasitic stub 252). The parasitic stub can also be used to reduce the voltage of the second switch 242 (and / or the third switch 243) to prevent the second switch 242 (and / or the third switch 243) from breaking down due to excessive voltage.

[0358] For the sake of simplicity, the parts of the antenna 200 shown in Figures 19 and 20 that are similar to the antenna 200 shown in Figures 16 and 17 are not repeated one by one. For example, the similar parts include: the position of the radiator 210, the frequency band of satellite communication; the resonance generated by the coupling of the radiator 210 with the first switch branch 231 or the second switch branch 232 at the first connection point 211; the current distribution of the floor 300 coupled with the first switch branch 231 or the second switch branch 232 at the first connection point 211; the value range of the equivalent device of the first switch branch 231 and the second switch branch 232; the position of the feeding point 221; the position of the grounding point 222; the position of the first connection point 211; and so on.

[0359] Figures 22 to 24 show simulation results for antenna 200 in electronic device 10 shown in Figure 20. Figure 22 shows the S-parameters of antenna 200 (with first connection point 211 coupled to first switch branch 231 and second connection point 212 coupled to third switch branch 233). Figure 23 shows the S-parameters of antenna 200 (with first connection point 211 coupled to second switch branch 232 and third connection point 213 coupled to fifth switch branch 235). Figure 24 shows simulation results for the radiation efficiency of antenna 200 (with connection points coupled to different switch branches).

[0360] As shown in Figure 22, the first connection point 211 is coupled to the first switch branch 231, and the second connection point 212 is coupled to the third switch branch 233. The antenna can resonate near 2.3 GHz and near 2.1 GHz. The resonance near 2.3 GHz corresponds to the first resonance in the above embodiment, and the resonance near 2.1 GHz corresponds to the third resonance in the above embodiment.

[0361] As shown in FIG23 , the first connection point 211 is coupled to the second switch branch 232, and the third connection point 213 is coupled to the fifth switch branch 235. The antenna can resonate near 2.2 GHz and near 1.8 GHz. The resonance near 2.2 GHz corresponds to the second resonance in the above embodiment, and the resonance near 1.8 GHz corresponds to the fourth resonance in the above embodiment.

[0362] As shown in FIG. 24 , in the first frequency band (eg, 2170 MHz-2200 MHz), antennas whose connection points are connected to different switch branches all have good radiation efficiency.

[0363] Moreover, compared with the case where the first parasitic branch or the second parasitic branch is not provided, the antenna generates a pit near 2.19 GHz, which corresponds to the first parasitic resonance or the second parasitic resonance in the above embodiment, and the radiation efficiency decreases by about 0.4 dB.

[0364] Figures 25 to 29 illustrate the directional patterns of antenna 200 at 2.2 GHz in the electronic device 10 shown in Figure 20 . Figure 25 illustrates a two-dimensional directional pattern generated by antenna 200 (with the first connection point 211 coupled to the first switch branch 231 and the second connection point 212 coupled to the third switch branch 233). Figure 26 illustrates a three-dimensional directional pattern generated by antenna 200 (with the first connection point 211 coupled to the first switch branch 231 and the second connection point 212 coupled to the third switch branch 233). Figure 27 illustrates a two-dimensional directional pattern generated by antenna 200 (with the first connection point 211 coupled to the second switch branch 232 and the third connection point 213 coupled to the fifth switch branch 235). Figure 28 illustrates a three-dimensional directional pattern generated by antenna 200 (with the first connection point 211 coupled to the second switch branch 232 and the third connection point 213 coupled to the fifth switch branch 235). Figure 29 illustrates the directional pattern formed by the superposition of the first and second directional patterns.

[0365] It should be understood that the first connection point 211 is coupled to the first switch branch 231, and the second connection point 212 is coupled to the third switch branch 233, so that the antenna 200 can generate the first directivity pattern in the above embodiment. The first connection point 211 is coupled to the second switch branch 232, and the third connection point 213 is coupled to the fifth switch branch 235, so that the antenna 200 can generate the second directivity pattern in the above embodiment.

[0366] As shown in FIG. 25 and FIG. 27 , the first and second directional patterns generated by the antenna have gains greater than or equal to 0 dBi within a range where Theta (θ) is less than 25°, and the antenna has good radiation characteristics.

[0367] The first connection point is coupled to the first switch branch, the second connection point is coupled to the third switch branch, and in the range of Theta (θ) greater than 25° and less than 70°, the first directional pattern is only In the range greater than 75° and less than 280°, the gain is greater than or equal to 0 dBi, as shown in Figure 25.

[0368] The first connection point is coupled to the first switch branch, and the second connection point is coupled to the third switch branch. The radiator, the first parasitic branch, and the second parasitic branch are used to generate a first radiation pattern of the antenna. The first parasitic branch can be used to adjust the angle between the maximum radiation direction of the first radiation pattern and the top direction, increasing the angle (deflecting the maximum radiation direction toward the first parasitic branch), as shown in Figure 26.

[0369] The first connection point is coupled with the second switch branch, the third connection point is coupled with the fifth switch branch, and in the range of Theta (θ) greater than 25° and less than 70°, the second directional pattern is only at Phi In the range greater than 0° and less than 120° and greater than 240° and less than 360°, the gain is greater than or equal to 0 dBi, as shown in Figure 27.

[0370] The first connection point is coupled to the second switch branch, and the third connection point is coupled to the fifth switch branch. The radiator, the first parasitic branch, and the second parasitic branch are used to generate a second radiation pattern of the antenna. The second parasitic branch can be used to adjust the angle between the maximum radiation direction of the second radiation pattern and the top direction, increasing the angle (deflecting the maximum radiation direction toward the second parasitic branch), as shown in Figure 28.

[0371] When the first and second patterns are superimposed (synthesized), the antenna exhibits good radiation characteristics within a range where Theta (θ) is less than 70°, as shown in Figure 29. When the communications satellite moves within this angular range (within 70° of the top direction), it remains within the region of electronic device 10 where the antenna exhibits good radiation characteristics, ensuring good communication between electronic device 10 and the communications satellite.

[0372] FIG30 is a schematic diagram of an electronic device 10 provided in an embodiment of the present application.

[0373] As shown in FIG. 30 , the electronic device 10 includes a frame 11 , an antenna 200 , and a floor 300 .

[0374] At least a portion of the frame 11 is spaced apart from the floor 300. The frame 11 includes a first side 131, and a second side 132 and a third side 133 that intersect the first side 131 at an angle. The length of the first side 131 is shorter than the length of the second side 132, and shorter than the length of the third side 133.

[0375] First side 131 includes a first position 201 and a second position 202. First side 131 or second side 132 also includes a third position 203. Second side 132 includes a fourth position 204. First side 131 or third side 133 also includes a fifth position 205. Third side 133 includes a sixth position 206. Frame 11 defines a first insulating gap and a second insulating gap in first position 201 and second position 202.

[0376] The antenna 200 includes a radiator 210 , a feeding circuit 220 , a first parasitic stub 251 , a second parasitic stub 252 , a third switch branch 233 , a fourth switch branch 234 , a fifth switch branch 235 , a sixth switch branch 236 , a second switch 242 , and a third switch 243 .

[0377] The radiator 210 includes a conductive portion of the frame 11 between the first position 201 and the second position 202. At least a portion of the radiator 210 is spaced apart from the floor 300.

[0378] The first parasitic branch 251 includes a conductive portion of the frame 11 between the third position 203 and the fourth position 204. The second parasitic branch 252 includes a conductive portion of the frame 11 between the fifth position 205 and the sixth position 206. At least a portion of the first parasitic branch 251 is spaced apart from the floor 300. At least a portion of the second parasitic branch 252 is spaced apart from the floor 300.

[0379] The radiator 210 includes a feeding point 221 , and the feeding circuit 220 is coupled to the feeding point 221 to feed an electrical signal into the antenna 200 .

[0380] The first parasitic branch 251 includes a second connection point 212. A third switch branch 233, a fourth switch branch 234, and a second switch 242 are coupled between the second connection point 212 and the floor 300. A first connection port of the second switch 242 is coupled to the third switch branch 233. A second connection port of the second switch 242 is coupled to the fourth switch branch 234. For ease of understanding, the third switch branch 233 and the fourth switch branch 234 can be considered to be connected in parallel.

[0381] Second parasitic branch 252 includes third connection point 213. Fifth switch branch 235, sixth switch branch 236, and third switch 243 are coupled between third connection point 213 and floor 300. A first connection port of third switch 243 is coupled to fifth switch branch 235. A second connection port of third switch 243 is coupled to sixth switch branch 236. For ease of understanding, third switch branch 233 and fourth switch branch 234 can be considered to be connected in parallel.

[0382] When the second connection point 212 is coupled to the third switch branch 233 via the second switch 242, and the third connection point 213 is coupled to the sixth switch branch 236 via the third switch 243, for example, the common port of the second switch 242 is coupled to the first connection port of the second switch 242, and the common port of the third switch 243 is coupled to the second connection port of the third switch 243. The radiator 210 is configured to generate a first resonance, wherein the resonant frequency band of the first resonance includes a first frequency band, which is at least a portion of the satellite communication frequency band.

[0383] In one embodiment, second connection point 212 is coupled to third switch branch 233 via second switch 242, and third connection point 213 is coupled to sixth switch branch 236 via third switch 243, thereby generating a first directivity pattern for antenna 200. In one embodiment, generating the first directivity pattern for antenna 200 can be considered to be generated by radiator 210, first parasitic stub 251, and second parasitic stub 252.

[0384] The second connection point 212 is coupled to the fourth switch branch 234 via the second switch 242, and the third connection point 213 is coupled to the fifth switch branch 235 via the third switch 243. For example, the common port of the second switch 242 is coupled to the second connection port of the second switch 242, and the common port of the third switch 243 is coupled to the first connection port of the third switch 243. The radiator 210 is configured to generate a second resonance, and the resonant frequency band of the second resonance includes the first frequency band.

[0385] It should be understood that when the electronic device 10 communicates with a communication satellite via the antenna 200, the operating frequency band of the antenna 200 may include a transmit frequency band and a receive frequency band within the satellite communication frequency band. In one embodiment, the feed circuit 220 is configured to transmit radio frequency signals within a first frequency band and radio frequency signals within a second frequency band.

[0386] In one embodiment, at the first time / time period, the resonant frequency band of the first resonance and the resonant frequency band of the second resonance in the above embodiment include a first frequency band, and the first frequency band may be a transmission frequency band in a satellite communication frequency band.

[0387] In one embodiment, at the first time / time period, the resonant frequency band of the first resonance and the resonant frequency band of the second resonance in the above embodiment include a second frequency band, and the second frequency band may be a receiving frequency band in a satellite communication frequency band.

[0388] In one embodiment, the first frequency band may be at least a portion of a frequency band between 1.5 GHz and 4.5 GHz. In one embodiment, the antenna 200 operates in the Tiantong satellite system, and the first frequency band may be a transmit frequency band (1980 MHz-2010 MHz) therein. In one embodiment, the antenna 200 operates in the Beidou satellite system, and the first frequency band may be a transmit frequency band (1610 MHz-1626.5 MHz) therein. In one embodiment, the antenna 200 operates in a low-orbit satellite system (e.g., StarNet), and the first frequency band may be a transmit frequency band (1668 MHz-1675 MHz) therein.

[0389] In one embodiment, the second frequency band may be at least a portion of a frequency band between 1.5 GHz and 4.5 GHz. In one embodiment, the antenna 200 operates in the Tiantong satellite system, and the second frequency band may be a receiving frequency band (2170 MHz-2200 MHz) therein. In one embodiment, the antenna 200 operates in the Beidou satellite system, and the second frequency band may be a receiving frequency band (2483.5 MHz-2500 MHz) therein. In one embodiment, the second frequency band may be a receiving frequency band (1518 MHz-1525 MHz) therein.

[0390] In one embodiment, antenna 200 may further include a tuning circuit. This tuning circuit is coupled to radiator 210 and configured to adjust the resonant frequency of the resonance generated by radiator 210 so that the resonant frequency range of the first resonance and the resonant frequency range of the second resonance include the first frequency range or the second frequency range, allowing antenna 200 to operate in the first frequency range and the second frequency range in different time slots. In one embodiment, the tuning circuit may include other switch branches coupled to the first connection point via first switch 241. This switch branch is configured to adjust the resonant frequency of the resonance generated by radiator 210 so that the resonant frequency range of the first resonance and the resonant frequency range of the second resonance include the first frequency range or the second frequency range. In one embodiment, the tuning circuit may include first switch branches 231 and second switch branches 232. The first switch branches 231 and second switch branches 232 may be configured to enable the resonant frequency range of the first resonance and the resonant frequency range of the second resonance generated by radiator 210 to include the first frequency range. Other switch branches may be configured to enable the resonant frequency range of the first resonance and the resonant frequency range of the second resonance generated by radiator 210 to include the second frequency range. For the sake of simplicity, in the embodiments of the present application, only the example of an antenna operating in a single frequency band is used for illustration.

[0391] In one embodiment, the second connection point 212 is coupled to the fourth switch branch 234 via the second switch 242, and the third connection point 213 is coupled to the fifth switch branch 235 via the third switch 243, so that the antenna 200 generates a second directional pattern. In one embodiment, the second directional pattern generated by the antenna 200 can be considered to be generated by the radiator 210, the first parasitic stub 251, and the second parasitic stub 252.

[0392] It should be understood that in the embodiment shown in FIG30 , at least one of the first parasitic stub 251 and the second parasitic stub 252, through corresponding components within the switch branch disposed thereon, causes the antenna 200 to generate a first pattern; and at least the other of the first parasitic stub 251 and the second parasitic stub 252, through corresponding components within the switch branch disposed thereon, causes the antenna 200 to generate a second pattern. Therefore, "antenna 200 generating the first pattern" can be understood as "radiator 210, first parasitic stub 251, second parasitic stub 252, third switch branch 233, and sixth switch branch 236 are used to generate the first pattern of antenna 200," and "antenna 200 generating the second pattern" can be understood as "radiator 210, first parasitic stub 251, second parasitic stub 252, fourth switch branch 234, and fifth switch branch 235 are used to generate the second pattern of antenna 200." A similar understanding can be applied to other embodiments of the present application.

[0393] In one embodiment, the sixth switch branch 236 can be used to prevent the second parasitic stub 252 from affecting the first pattern. In one embodiment, the sixth switch branch 236 may not include electronic components and can directly electrically connect the third connection point 213 to the floor 300. The third connection point 213 is coupled to the sixth switch branch 236 via the third switch 243, and the third connection point 213 is coupled to the floor 300, which is equivalent to not having the second parasitic stub 252. In one embodiment, the sixth switch branch 236 can include electronic components that can distance the parasitic resonance generated by the second parasitic stub 252 from the resonance generated by the radiator 210 (e.g., with a frequency difference greater than or equal to 300 MHz).

[0394] Among them, the second parasitic branch 252 does not affect the first direction pattern in various ways (for example, the third connection point 213 is coupled with the branch of the floor 300). It can also be understood that the second parasitic branch 252 is used to generate the second direction pattern together with the radiator 210 and the first parasitic branch 251.

[0395] In one embodiment, the fourth switch branch 234 can be used to prevent the first parasitic stub 251 from affecting the second pattern. In one embodiment, the fourth switch branch 234 may not include electronic components and can directly electrically connect the second connection point 212 to the floor 300. When the first connection point 211 is coupled to the second switch branch 232, the second connection point 212 is coupled to the fourth switch branch 234 via the second switch 242, and the floor 300 is coupled to the second connection point 212, this is equivalent to not having the first parasitic stub 251. In one embodiment, the fourth switch branch 234 can include electronic components that can distance the parasitic resonance generated by the first parasitic stub 251 from the resonance generated by the radiator 210 (e.g., with a frequency difference greater than or equal to 300 MHz).

[0396] Among them, the first parasitic branch 251 does not affect the second direction pattern in various ways (for example, the second connection point 212 is coupled with the floor 300 branch). It can also be understood that the first parasitic branch 251 is used to generate the second direction pattern together with the radiator 210 and the second parasitic branch 252.

[0397] In one embodiment, the maximum radiator direction of the first directional pattern is a first direction, the maximum radiator direction of the second directional pattern is a second direction, and the first direction and the second direction are different.

[0398] It should be understood that in the first switching state, compared to when the first parasitic branch 251 is not provided (for example, when the second connection point 212 is coupled to the sixth switch branch), the first direction is deflected toward the side where the first parasitic branch 251 is located. In the second on state, compared to when the second parasitic branch 252 is provided (for example, when the third connection point 213 is coupled to the fourth switch branch), the second direction is deflected toward the side where the second parasitic branch 252 is located. The first parasitic branch 251 and the second parasitic branch 252 can be used to deflect the directional pattern generated by the antenna 200 in the first switching state and the second switching state toward the top direction (the direction from the bottom of the electronic device to the top, for example, the z-direction) on both sides (the side where the first parasitic branch 251 is located and the side where the second parasitic branch 252 is located). The antenna 200 can switch the first directional pattern and the second directional pattern generated by the antenna 200 according to the communication status (for example, including the relative position) between the communication satellite and the electronic device 10 to switch the maximum radiation direction of the directional pattern generated by the antenna 200, thereby ensuring the communication quality between the communication satellite and the electronic device 10.

[0399] Therefore, the electronic device 10 has good communication characteristics within a range of relatively large angles (e.g., 50°, 60°, or 70°) relative to the top direction (the direction from the bottom of the electronic device to the top, such as the z-direction). For example, when a user is performing satellite communication, the antenna 200 has a wide beam characteristic, and the directional pattern generated by the antenna 200 has good characteristics within a relatively large angle, effectively improving the user experience.

[0400] It should be understood that in the embodiments of the present application (for example, the electronic device 10 shown in FIG30 ), the antenna 200 is described as being in the same operating state. The same operating state can be understood as meaning that the operating frequency band of the antenna 200 may include the first frequency band, and the antenna 200 can communicate in the first frequency band when the second switch 242 is coupled to the third switch branch 233 or the fourth switch branch 234, and when the third switch 243 is coupled to the fifth switch branch 235 or the sixth switch branch 236.

[0401] It should be understood that the antenna 200 shown in FIG30 differs from the antenna 200 shown in FIG19 only in the first switch branch 231, the second switch branch 232, and the first switch 241. In the antenna 200 shown in FIG16, the first switch branch 231, the second switch branch 232, and the first switch 241 are not provided.

[0402] It should be understood that whether switches and switch branches are set on the radiator 210, or whether switches and switch branches are not set on the radiator 210, the devices set in the third switch branch 233 set on the first parasitic branch 251 can be the same or different, the equivalent device values ​​of the third switch branch 233 can be the same or different, and the specific form of the third switch branch 233 can be selected according to the target radiation pattern; similarly, whether switches and switch branches are set on the radiator 210, the specific form of the fourth switch branch 234 set on the first parasitic branch 251, the fifth switch branch 235 set on the second parasitic branch 252, or the sixth switch branch 236 set on the second parasitic branch 252 can also be selected according to the target radiation pattern.

[0403] In the antenna 200 shown in Figure 19, the first switch 241 is used to switch the switch branch coupled to the first connection point 211 in different switching states, adjust the current distribution on the floor 300 on both sides of the virtual axis, and deflect the maximum radiation direction of the directional pattern generated by the antenna 200 in different switching states.

[0404] Furthermore, in antenna 200 shown in FIG19 , the angle between the maximum radiation direction of the directional pattern generated by antenna 200 and the top direction can be further adjusted in different switching states through first parasitic branch 251 and second parasitic branch 252, thereby further increasing this angle. These two approaches ensure that antenna 200 maintains good communication characteristics over a wide range of angles relative to the top direction (the direction from the bottom of the electronic device to the top, for example, the z-direction).

[0405] In the antenna 200 shown in Figure 30, the first switch branch 231, the second switch branch 232 and the first switch 241 are not set. Only the first parasitic branch 251 and the second parasitic branch 252 are used to adjust the maximum radiation direction of the directional pattern generated by the antenna 200 in different switching states, so that the antenna 200 has good communication characteristics within a range of a larger angle with the top direction (the direction from the bottom of the electronic device to the top, for example, the z direction).

[0406] In one embodiment, the first parasitic branch 251 and the second parasitic branch 252 can be of any structure, and the embodiments of the present application do not limit this. In one embodiment, the frame 11 can have an insulating gap at the third position 203 and the fourth position 204, and / or an insulating gap at the fifth position 205 and the sixth position 206, and the first parasitic branch 251 and / or the second parasitic branch 252 can be a dipole-like antenna structure. In one embodiment, the frame 11 can have an insulating gap between the third position 203 and the fourth position 204, and / or an insulating gap between the fifth position 205 and the sixth position 206, and the first parasitic branch 251 and / or the second parasitic branch 252 can be an antenna structure composed of multiple branches. For the sake of simplicity of discussion, in the embodiments of the present application, only one end of the first parasitic branch 251 and the second parasitic branch 252 is open and the other end is grounded for description. The frame 11 is coupled to the floor 300 at the third position 203 and has a third insulating gap at the fourth position 204. The frame 11 is coupled to the floor 300 at the third position 203 and has a fourth insulating gap at the sixth position 206, as shown in FIG31 .

[0407] In one embodiment, an angle between the first direction and the second direction is greater than or equal to 10° and less than or equal to 90°.

[0408] It should be understood that when the first radiation pattern, the maximum radiation direction of the first radiation pattern and the maximum radiation direction of the second radiation pattern are offset toward both sides of the top direction (there is a larger angle between the first direction and the second direction), the width of the radiation beam of the antenna 200 can be further widened, so that the antenna 200 has good communication characteristics within a wider angle range (the angle with the top direction).

[0409] In one embodiment, the radiator 210 may not include a ground point.

[0410] It should be understood that the first and second resonances described above are generated by the linear DM mode described in the above embodiments. Since the current generated in the linear DM mode is primarily generated by radiator 210 and is concentrated on radiator 210, multiple current modes are not generated on floor 300, making it easier to determine the maximum radiation direction of the antenna 200's pattern. Furthermore, in the linear DM mode, the antenna's radiation is primarily generated by the radiator, resulting in superior system efficiency and radiation efficiency compared to the linear CM mode.

[0411] In one embodiment, the second connection point 212 is coupled to the third switch branch 233 through the second switch 242, and the third connection point 213 is coupled to the sixth switch branch 236 through the third switch 243. When the antenna 200 operates in the first frequency band or the second frequency band, the current on the radiator 210 and the current on the first parasitic branch 251 are in the same direction (the current path is clockwise or counterclockwise).

[0412] In one embodiment, the second connection point 212 is coupled to the fourth switch branch 234 through the second switch 242, and the third connection point 213 is coupled to the fifth switch branch 235 through the third switch 243. When the antenna 200 operates in the first frequency band or the second frequency band, the current on the radiator 210 and the current on the second parasitic branch 252 are in the same direction (the current path is clockwise or counterclockwise).

[0413] It should be understood that when the current on the radiator 210 is in the same direction as the current on the parasitic branch (the first parasitic branch 251 or the second parasitic branch 252 ), the bandwidth of the radiation beam can be better broadened, so that the antenna 200 has better radiation characteristics in a wider angle range.

[0414] In one embodiment, the third position 203 is located between the fourth position 204 and the second position 202. The fifth position 205 is located between the sixth position 206 and the first position 201.

[0415] It should be understood that for the sake of simplicity of discussion, in the embodiments of the present application, only the above-mentioned structure is used as an example for illustration. In actual production or design, the fourth position 204 may also be located between the third position 203 and the second position 202, and the sixth position 206 may be located between the fifth position 205 and the first position 201. The embodiments of the present application do not limit this and will not be described one by one.

[0416] In one embodiment, the second connection point 212 is coupled to the third switch branch 233 via the second switch 242, and the third connection point 213 is coupled to the sixth switch branch 236 via the third switch 243. The feed circuit 220 feeds an electrical signal, the radiator 210 is configured to generate a first main resonance, and the first parasitic stub 251 is configured to generate a first parasitic resonance. The second connection point 212 is coupled to the fourth switch branch 234 via the second switch 242, and the third connection point 213 is coupled to the fifth switch branch 235 via the third switch 243. The feed circuit 220 feeds an electrical signal, the radiator 210 is configured to generate a second main resonance, and the second parasitic stub 252 is configured to generate a second parasitic resonance.

[0417] The first main resonance and the first parasitic resonance together form the above-mentioned first resonance, and the second main resonance and the second parasitic resonance together form the above-mentioned second resonance (due to the small frequency difference between the resonance point of the parasitic resonance and the resonance point of the main resonance, in the S-parameter diagram, the main resonance and the parasitic resonance are merged into one resonance). In one embodiment, the resonance point of the parasitic resonance is located within the resonance frequency band of the main resonance. In one embodiment, the frequency difference between the resonance point frequency of the parasitic resonance and the resonance point frequency of the main resonance is less than or equal to 100 MHz. In one embodiment, the frequency difference between the resonance point frequency of the parasitic resonance and the resonance point frequency of the main resonance is less than or equal to 50 MHz. In one embodiment, the resonance point frequency of the parasitic resonance can be less than the resonance point frequency of the main resonance.

[0418] At the same time, in an embodiment of the present application, the coupling between the radiator 210 and the parasitic branch (the first parasitic branch 251 or the second parasitic branch 252) is weak, and the parasitic resonance cannot be well excited. Therefore, the pit corresponding to the parasitic resonance does not appear clearly in the S-parameter diagram. However, since the parasitic resonance is partially excited by current, an obvious pit will appear in the efficiency curve (for example, radiation efficiency or system efficiency). For example, if an efficiency pit appears at the first frequency point, the first frequency point can be considered to correspond to the resonance point of the above-mentioned first parasitic resonance or second resonance. In one embodiment, the efficiency (for example, radiation efficiency or system efficiency) caused by the pit does not exceed 1.5dB. In one embodiment, the efficiency (for example, radiation efficiency or system efficiency) caused by the pit does not exceed 1dB.

[0419] In one embodiment, the resonance point frequency of the first resonance (first main resonance) and the resonance point frequency of the second resonance (second main resonance) are substantially the same. In one embodiment, the frequency difference between the resonance point frequency (first main resonance) and the resonance point frequency of the second resonance (second main resonance) is less than or equal to 50 MHz.

[0420] In one embodiment, the distance between the first parasitic stub 251 or the second parasitic stub 252 and the radiator 210 in the third direction is less than half the length of the second side 132 (or the third side 133). The third direction is the extending direction of the second side 132 (or the third side 133), for example, the top direction (z direction).

[0421] It should be understood that the first parasitic branch 251 can be located at the midpoint of the second side 132 on the side close to the first side 131, and the second parasitic branch 252 can be located at the midpoint of the third side 133 on the side close to the first side 131, so that the first parasitic branch 251 and the second parasitic branch 252 can be better excited, so that the antenna 200 has better radiation characteristics.

[0422] In one embodiment, the conductor portion between the third position 203 and the second position 202 and / or the conductor portion between the first position 201 and the fifth position 205 may also serve as a parasitic stub, as shown in FIG. 32 .

[0423] It should be understood that the parasitic stub (the parasitic stub formed by the conductor portion between the third position 203 and the second position 202 and / or the conductor portion between the first position 201 and the fifth position 205) is used to improve the radiation characteristics of the antenna 200 (e.g., improve efficiency). The parasitic stub can also be used to increase the coupling between the first parasitic stub 251 (and / or the second parasitic stub 252) and the radiator 210 to better stimulate the first parasitic stub 251 (and / or the second parasitic stub 252). The parasitic stub can also be used to reduce the voltage of the second switch 242 (and / or the third switch 243) to prevent the second switch 242 (and / or the third switch 243) from breaking down due to excessive voltage.

[0424] Figures 33 to 35 show simulation results for antenna 200 in electronic device 10 shown in Figure 31 . Figure 33 shows the S-parameters of antenna 200 (second connection point 212 coupled to third switch branch 233, third connection point 213 coupled to sixth switch branch 236). Figure 34 shows the S-parameters of antenna 200 (second connection point 212 coupled to fourth switch branch 234, third connection point 213 coupled to fifth switch branch 235). Figure 35 shows the simulation results of the radiation efficiency of antenna 200 (connection points coupled to different switch branches).

[0425] As shown in FIG33 , the second connection point is coupled to the third switch branch via the second switch, and the third connection point is coupled to the sixth switch branch via the third switch, so that the antenna can resonate near 2.2 GHz. The resonance generated near 2.2 GHz may correspond to the first resonance in the above embodiment.

[0426] As shown in FIG34 , the second connection point is coupled to the fourth switch branch via the second switch, and the third connection point is coupled to the fifth switch branch via the third switch, so that the antenna can resonate near 2.2 GHz. The resonance near 2.2 GHz may correspond to the second resonance in the above embodiment.

[0427] As shown in FIG33 and FIG34 , the resonance point frequency of the first resonance and the resonance point frequency of the second resonance are substantially the same.

[0428] As shown in FIG35 , in the first frequency band (eg, 2170 MHz-2200 MHz), antennas whose connection points are connected to different switch branches all have good radiation efficiency.

[0429] Furthermore, in the first switching state and the second switching state, the antenna generates a pit near 2.1 GHz, which may correspond to the first parasitic resonance or the second parasitic resonance in the above embodiment, and the radiation efficiency decreases by about 0.5 dB.

[0430] Figures 36 to 38 illustrate the directional patterns of antenna 200 at 2.2 GHz in electronic device 10 shown in Figure 31 . Figure 36 illustrates the directional pattern generated by antenna 200 (with second connection point 212 coupled to third switch branch 233, and third connection point 213 coupled to sixth switch branch 236). Figure 37 illustrates the directional pattern generated by antenna 200 (with second connection point 212 coupled to fourth switch branch 234, and third connection point 213 coupled to fifth switch branch 235). Figure 38 illustrates the directional pattern formed by superimposing the first and second directional patterns.

[0431] It should be understood that when the second connection point 212 is coupled to the third switch branch 233 and the third connection point 213 is coupled to the sixth switch branch 236, the antenna 200 can generate the first directional pattern in the above embodiment. When the second connection point 212 is coupled to the fourth switch branch 234 and the third connection point 213 is coupled to the fifth switch branch 235, the antenna 200 can generate the second directional pattern in the above embodiment.

[0432] As shown in FIG36 and FIG37 , the first and second directional patterns generated by the antenna have gains greater than or equal to 0 dBi within a range where Theta (θ) is less than 40°, and the antenna has good radiation characteristics.

[0433] In the range of Theta (θ) greater than 40° and less than 70°, the first pattern is only In the range greater than 90° and less than 270°, the gain is greater than or equal to 0 dBi, as shown in Figure 36.

[0434] In the range of Theta (θ) greater than 40° and less than 70°, the second pattern is only In the range greater than 0° and less than 90° and greater than 270° and less than 360°, the gain is greater than or equal to 0 dBi, as shown in Figure 37.

[0435] When the first and second patterns are superimposed (synthesized), the antenna exhibits good radiation characteristics within a range where Theta (θ) is less than 70°, as shown in FIG38 . When the communication satellite moves within this angular range (within 70° of the top direction), it remains within the region of electronic device 10 where the antenna exhibits good radiation characteristics, ensuring good communication between electronic device 10 and the communication satellite.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
