Description
Technical Field
[0001] This application relates to the field of wireless communication, and particularly to an electronic device. Background Art
[0002] With the continuous evolution of mobile communication technology, satellite communication technology has gradually become a major feature function in mobile terminal devices.
[0003] When an electronic device conducts satellite communication, for example, communicates with a geostationary orbit satellite at 36,000 km, the satellite communication system usually requires a very high transmission power. In order to prevent high-power electrical signals from being injected into the RF channels of antennas that are proximally arranged to the satellite communication antenna during the signal transmission process of the satellite communication antenna in the electronic device, resulting in damage to the electronic components in the RF circuit or interference to the received signals, therefore, usually when the satellite communication antenna is working, the antennas that are proximally arranged in the electronic device do not work.
[0004] However, this also makes it impossible for the electronic device to communicate through the antennas that are proximally arranged to the satellite communication antenna during satellite communication, and the electronic device loses some functions (such as navigation), which causes inconvenience to users in use. Summary of the Invention
[0005] This application provides an electronic device, which includes a first antenna and a second antenna. Both the first antenna and the second antenna use the conductive part of the frame of the electronic device as a radiator. Among them, the operating frequency band of the first antenna includes the satellite communication frequency band, and the operating frequency band of the second antenna includes the satellite navigation frequency band. When the electronic device conducts satellite communication through the first antenna, the electronic device can also simultaneously conduct satellite navigation through the second antenna, improving the user experience during satellite communication.
[0006] In a first aspect, an electronic device is provided, including: a floor; a frame, the frame including a first position, a second position, a third position, and a fourth position arranged in sequence; a first antenna, the operating frequency band of the first antenna including a first frequency band, the first antenna including: a first radiator, the first radiator being a conductive portion of the frame between the first position and the second position, at least a portion of the first radiator being spaced apart from the floor, a first modem, the first modem being coupled to the first radiator; a second antenna, the operating frequency band of the second antenna including a second frequency band, the second antenna including: a second radiator, the second radiator being a conductive portion of the frame between the third position and the fourth position, at least a portion of the second radiator being spaced apart from the floor, a second modem, the second modem being coupled to the second radiator, the first modem being coupled to the second modem; wherein, the first modem sends a first signal to the second modem, the first signal being used to instruct the first antenna to send a signal at a first moment; the second modem deletes or replaces a second signal received by the second antenna at the first moment according to the first signal; the first frequency band includes a satellite communication frequency band, and the second frequency band includes a satellite navigation frequency band.
[0007] According to the embodiments of the present application, the radiators of the first antenna and the second antenna are different (the first radiator and the second radiator do not overlap, and the first antenna and the second antenna do not share a radiator), and there is good isolation between the first antenna and the second antenna. When the first antenna and the second antenna work simultaneously, the first antenna transmitting a signal will not damage the electronic components in the RF circuit of the second antenna.
[0008] Moreover, when the first antenna and the second antenna work simultaneously, the first modem sends a first signal to the second modem, and the second modem determines that the first antenna 210 sends a signal at the first moment through the first signal. The second modem processes the second signal received by the second antenna at the first moment, so that the second antenna is not affected by the signal sent by the first antenna, and the first antenna and the second antenna can work simultaneously.
[0009] Combined with the first aspect, in some implementation manners of the first aspect, that the second modem deletes the second signal received by the second antenna at the first moment according to the first signal further includes: based on the first moment corresponding to a first time slot in a plurality of first sub-frames, the second modem deletes the signals stored in the plurality of first time slots, and the second modem combines the plurality of first sub-frames into a second sub-frame.
[0010] According to an embodiment of the present application, when the first antenna transmits a signal at a first moment (for example, the first moment is from time slot 4 to time slot 6 in subframe 1 and from time slot 1 to time slot 3 in subframe 2), the second modem deletes the signals received by the second antenna from time slot 4 to time slot 6 in subframe 1 and from time slot 1 to time slot 3 in subframe 2. Since there will be some duplicate information in the signals received by the second antenna stored in adjacent subframes, the subframes corresponding to the first moment (subframe 1 and subframe 2) can be combined into a new subframe, and no information will be lost in this subframe. Therefore, the second antenna can work simultaneously with the first antenna without affecting the integrity of the signals received by the second antenna, so that the user can perform satellite communication without losing other functions, such as satellite navigation.
[0011] In combination with the first aspect, in some implementation manners of the first aspect, the second modem replaces the second signal received by the second antenna at the first moment according to the first signal, including: the second modem replaces the second signal with a third signal, where the third signal is a default signal, or the third signal is a signal stored in a time slot corresponding to the first moment in a second subframe, the second subframe is adjacent to a first subframe, and the first subframe includes the time slot corresponding to the first moment.
[0012] According to an embodiment of the present application, when the first antenna transmits a signal at a first moment (for example, the first moment is from time slot 4 to time slot 6 in subframe 1), the second modem replaces the signals stored in time slot 4 to time slot 6 in subframe 1 with the signals stored in the corresponding time slots (time slot 4 to time slot 6 in subframe 2) in the adjacent subframe 2, and no information will be lost in subframe 1. Therefore, the second antenna can work simultaneously with the first antenna without affecting the integrity of the information received by the second antenna, so that the user can perform satellite communication without losing other functions, such as satellite navigation.
[0013] In combination with the first aspect, in some implementation manners of the first aspect, the frame further includes a first side and a second side that intersect at an angle, and the length of the first side is less than the length of the second side; the second position and the third position are located on the first side of the frame.
[0014] According to an embodiment of the present application, at least part of the radiators of the first radiator and the second radiator are located on the first side, which can facilitate the first antenna and the second antenna to generate radiation towards the top of the electronic device (the maximum radiation direction of the radiation pattern is towards the top of the electronic device, for example, the y direction). When the first antenna is a satellite communication antenna, the maximum radiation direction is towards the top of the electronic device, which is convenient for the electronic device to point to the satellite (establish a communication connection with the satellite) when performing satellite communication. When the second antenna is a satellite navigation antenna, it is convenient for the electronic device to achieve precise positioning.
[0015] In combination with the first aspect, in some implementations of the first aspect, the isolation between the first antenna and the second antenna is greater than or equal to 20 dB.
[0016] In combination with the first aspect, in some implementations of the first aspect, the second frequency band includes the L1 band in GPS.

[0018] According to the embodiments of the present application, for a received signal, the power of the received signal is small. For example, when the operating frequency band of the second antenna includes a satellite navigation frequency band, the power of the received signal is only about -130 dB. When the signal transmitted in the baseband chip is in a saturated state (the saturated state can be understood as the power of the signal being greater than a threshold, for example, 0 dB), it can be considered that the abnormal power of the signal is affected by the high-power signal transmitted by the first antenna, and part of the power is transmitted to the radio frequency circuit of the second antenna, then the part of the signal in the saturated state is deleted. The baseband chip processes the signal received by the second antenna in the saturated state, so that the second antenna is not affected by the signal transmitted by the first antenna, and the first antenna and the second antenna can work simultaneously.

[0027] According to an embodiment of the present application, in a first subframe, the first antenna sends a signal at a first moment (for example, time slots 1, 2, 4, 5 in subframe 1), and the second antenna receives a signal at a second moment (for example, time slots 7, 8 in subframe 2). Since the second antenna does not receive a signal at the first moment, the second antenna is not affected by the signal sent by the first antenna, and the first antenna and the second antenna can work simultaneously in the first subframe.

[0042] The technical solutions in the present application will be described below with reference to the accompanying drawings.
[0043] It should be understood that the term "and / or" used herein is only a description of the same field of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after.
[0044] The term "within... range" used in the present application, unless otherwise specified as not including the end values, is default to include the two end values of the range. For example, within the range of 1 to 5, both the values 1 and 5 are included.
[0045] Coupling: It can be understood as direct coupling and / or indirect coupling. "Coupling connection" can be understood as direct coupling connection and / or indirect coupling connection. Direct coupling can also be called "electrical connection", which is understood as physical contact and electrical conduction between components; it can also be understood as a form of connection between different components in a circuit structure through physical lines such as copper foils or wires on a printed circuit board (PCB) that can transmit electrical signals. "Indirect coupling" can be understood as electrical conduction between two conductors in a non-contact manner through air. In one embodiment, indirect coupling can also be called capacitive coupling. For example, signal transmission is achieved by forming an equivalent capacitance through the coupling between the gaps of two spaced conductive parts.
[0046] Element / device: Includes at least one of lumped elements / devices and distributed elements / devices.
[0047] Lumped element / device: It refers to the general term for all elements when the size of the element is much smaller than the wavelength corresponding to the operating frequency of the circuit. For a signal, regardless of the time, the characteristics of the element always remain fixed and are independent of frequency.
[0048] Distributed element / device: Different from lumped elements, when the size of the element is about the same as or larger than the wavelength corresponding to the operating frequency of the circuit, when a signal passes through the element, the characteristics of each point of the element itself will vary with the change of the signal. At this time, the element as a whole cannot be regarded as a single entity with fixed characteristics, but should be called a distributed element.
[0049] Capacitance: It can be understood as lumped capacitance and / or distributed capacitance. Lumped capacitance refers to components with capacitive properties, such as capacitor elements; distributed capacitance (or distributed capacitor) refers to the equivalent capacitance formed by two conductive parts spaced apart by a certain gap.
[0050] Inductance: It can be understood as lumped inductance and / or distributed inductance. Lumped inductance refers to components with inductive properties, such as inductor elements; distributed inductance (or distributed inductor) refers to the equivalent inductance formed by a conductive part of a certain length.
[0051] Radiator: It is a device in an antenna used to receive / transmit electromagnetic wave radiation. In some cases, "antenna" is narrowly understood as a radiator, which converts the guided wave energy from a transmitter into radio waves, or converts radio waves into guided wave energy, for radiating and receiving radio waves. The modulated high-frequency current energy (or guided wave energy) generated by the transmitter is transmitted to the transmitting radiator through a feeder line. Through the radiator, it is converted into electromagnetic wave energy of a certain polarization and radiated in the required direction. The receiving radiator converts the electromagnetic wave energy of a certain polarization from a specific direction in space back into modulated high-frequency current energy and transmits it to the input end of the receiver through the feeder line.
[0052] The radiator may include a conductor with a specific shape and size, such as linear or sheet-like, etc. The present application does not limit the specific shape. In one embodiment, the linear radiator may be simply referred to as a wire antenna. In one embodiment, the linear radiator may be implemented by a conductive frame and may also be referred to as a frame antenna. In one embodiment, the linear radiator may be implemented by a support conductor and may also be referred to as a support antenna. In one embodiment, the wire diameter (e.g., including thickness and width) of the linear radiator, or the radiator of the wire antenna, is much smaller than the wavelength (e.g., the dielectric wavelength) (e.g., less than 1 / 16 of the wavelength), and the length can be comparable to the wavelength (e.g., the dielectric wavelength) (e.g., the length is around 1 / 8 of the wavelength, or 1 / 8 to 1 / 4, or 1 / 4 to 1 / 2, or longer). The main forms of wire antennas include dipole antennas, half-wave dipole antennas, monopole antennas, loop antennas, inverted-F antennas (also known as IFA, Inverted F Antenna). For example, for a dipole antenna, each dipole antenna generally includes two radiating branches, and each branch is fed by a feeding portion from the feeding end of the radiating branch. For example, an inverted-F antenna (Inverted-F Antenna, IFA) can be regarded as obtained by adding a grounding path to a monopole antenna. The IFA antenna has a feeding point and a grounding point, and is called an inverted-F antenna because its side view is in the shape of an inverted F. In one embodiment, the sheet radiator may include a microstrip antenna, or a patch antenna, such as a planar inverted-F antenna (also known as PIFA, Planar Inverted F Antenna). In one embodiment, the sheet radiator may be implemented by a planar conductor (such as a conductive sheet or a conductive coating, etc.). In one embodiment, the sheet radiator may include a conductive sheet, such as a copper sheet. In one embodiment, the sheet radiator may include a conductive coating, such as silver paste. The shape of the sheet radiator includes circular, rectangular, annular, etc. The present application does not limit the specific shape. The structure of a microstrip antenna generally consists of a dielectric substrate, a radiator, and a ground plane, where the dielectric substrate is disposed between the radiator and the ground plane.
[0053] The radiator may also include a groove or a slit formed on a conductor. For example, a closed or semi-closed groove or slit is formed on a grounded conductor surface. In one embodiment, the slotted or slit radiator may be simply referred to as a slot antenna or a slit antenna. In one embodiment, the radial dimension (e.g., including the width) of the slot or slit of the slot antenna / slit antenna is much smaller than the wavelength (e.g., the dielectric wavelength) (e.g., less than 1 / 16 of the wavelength), and the length dimension can be comparable to the wavelength (e.g., the dielectric wavelength) (e.g., the length is around 1 / 8 of the wavelength, or 1 / 8 to 1 / 4, or 1 / 4 to 1 / 2, or longer). In one embodiment, the radiator with a closed slot or slit may be simply referred to as a closed slot antenna. In one embodiment, the radiator with a semi-closed slot or slit (e.g., adding an opening to the closed slot or slit) may be simply referred to as an open slot antenna. In some embodiments, the shape of the slit is elongated. In some embodiments, the length of the slit is about half a wavelength (e.g., the dielectric wavelength). In some embodiments, the length of the slit is about an integer multiple of the wavelength (e.g., one dielectric wavelength). In some embodiments, the slit can be fed by a transmission line bridging one or both of its sides. Thus, a radio frequency electromagnetic field is excited on the slit and radiates electromagnetic waves into space. In one embodiment, the radiator of the slot antenna or the slit antenna can be implemented by a conductive frame grounded at both ends, and can also be referred to as a frame antenna; in this embodiment, it can be considered that the slot antenna or the slit antenna includes a linear radiator, the linear radiator is spaced from the floor and grounded at both ends of the radiator, so as to form a closed or semi-closed slot or slit. In one embodiment, the radiator of the slot antenna or the slit antenna can be implemented by a support conductor grounded at both ends, and can also be referred to as a support antenna.
[0054] The feeding circuit is a combination of all circuits for receiving and transmitting radio frequency signals. The feeding circuit may include a transceiver and a radio frequency front-end circuit (RF front end). In some cases, "feeding circuit" is narrowly understood as a radio frequency integrated circuit (RFIC), and the RFIC can be considered to include a radio frequency front-end chip and a transceiver. The feeding circuit has the function of converting radio waves (e.g., radio frequency signals) and electrical signals (e.g., digital signals). Generally, it is considered as a part of the radio frequency.
[0055] In some embodiments, the electronic device may further include a test socket (or referred to as a radio frequency socket or a radio frequency test socket). This test socket can be used to insert a coaxial cable to test the characteristics of the radio frequency front-end circuit or the radiator of the antenna through the cable. The radio frequency front-end circuit can be considered as the circuit part coupled between the test socket and the transceiver.
[0056] In some embodiments, the radio frequency front-end circuit can be integrated into a radio frequency front-end chip in an electronic device, or the radio frequency front-end circuit and the transceiver can be integrated into a radio frequency chip in the electronic device.
[0057] It should be understood that any two of the first / second / ... / Nth feeding circuits in this application can share the same transceiver. For example, signals can be transmitted through a radio frequency channel in a transceiver (e.g., a port (pin) of a radio frequency chip); they can also share a radio frequency front-end circuit. For example, signals can be processed by a switch or an amplifier in a radio frequency front-end.
[0058] It should also be understood that two of the first / second / ... / Nth feeding circuits in this application generally correspond to two radio frequency test sockets in an electronic device.
[0059] The matching circuit is a circuit for adjusting the radiation characteristics of the antenna. In one embodiment, the matching circuit is coupled between the feeding circuit and the corresponding radiator. In one embodiment, the matching circuit is coupled between the test socket and the radiator. Generally, the matching circuit is a combination of circuits coupled between the radiator and the ground plane. In one embodiment, the matching circuit can include switches and / or electronic components. The switch can be an electronic component for switching the coupled connection of the radiator. The matching circuit has the functions of impedance matching and / or frequency tuning. Generally, it is considered to be a part of the antenna.
[0060] The grounding structure / feeding structure. The grounding structure / feeding structure can include connecting parts, such as metal shrapnel. The radiator is coupled to the ground plane through the grounding structure / the feeding structure is coupled to the feeding circuit. In some embodiments, the feeding structure can include a transmission line / feeding wire, and the grounding structure can include a grounding wire.
[0061] 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 endpoint or end part that is physically disconnected from other radiators. It can also be considered as a certain point or a certain section on a continuous radiator. In one embodiment, the "end / point" can include the connection / coupling area on the antenna radiator that is coupled to other conductive structures. For example, the feeding end / feeding point can be the coupling area on the antenna radiator that is coupled to the feeding structure (e.g., the area facing a part of the feeding structure), and for another example, the grounding end / grounding point can be the connection / coupling area on the antenna radiator that is coupled to the grounding structure.
[0062] Open end, closed end: In some embodiments, the open end and the closed end are, for example, defined relative to whether they are grounded. The closed end is grounded, and the open end is not grounded. In some embodiments, the open end and the closed end are, for example, defined relative to other conductive bodies. The closed end is electrically connected to other conductive bodies, and the open end is not electrically connected to other conductive bodies. In one embodiment, the open end can also be referred to as a floating end, a free end, an open end, or an open-circuit end. In one embodiment, the closed end can also be referred to as a grounded end or a short-circuit end. It should be understood that in some embodiments, other conductive bodies can be coupled and connected through the open end to transfer coupled energy (which can be understood as transferring current).
[0063] In some embodiments, the understanding of the "closed end" can also be from the perspective of current distribution. The closed end or the grounded end, etc., can be understood as the current maxima on the radiator or the electric field minima on the radiator; in one embodiment, coupling electronic devices (such as capacitors, inductors, etc.) through the closed end does not change the current distribution characteristics of its current maxima / electric field minima; in one embodiment, making a slit (such as a slit filled with an insulating material) at or near the closed end does not change the current distribution characteristics of its current maxima / electric field minima.
[0064] In some embodiments, the understanding of the "open end" can also be from the perspective of current distribution. The open end or the floating end, etc., can be understood as the current minima on the radiator or the electric field maxima on the radiator; in one embodiment, coupling electronic devices (such as capacitors, inductors, etc.) through the open end does not change the current distribution characteristics of its current minima / electric field maxima.
[0065] It should be understood that coupling an electronic device (such as a capacitor, an inductor, etc.) to the radiator end at a slit (from the structure of the radiator, similar to the opening of an open end or a floating end) can make the radiator end the current maxima / electric field minima. In this case, it should be understood that the radiator end at this slit is actually the closed end or the grounded end, etc.
[0066] The "floating radiator" mentioned in the embodiments of the present application refers to a radiator that is not directly connected to the feeder / feeding stub and / or the ground wire / grounding stub, but is fed and / or grounded through an indirect coupling method.
[0067] It should be understood that the "floating" in the "floating end" and the "floating radiator" does not mean that there is no structure around the radiator to support it. In one embodiment, the floating radiator can be, for example, a radiator disposed on the inner surface of an insulating rear cover.
[0068] Resonance / Resonant Frequency: The resonant frequency is also called the resonance frequency. The resonant frequency can have a frequency range, that is, the frequency range where resonance occurs. The frequency corresponding to the strongest resonance point is the center frequency point. The return loss characteristic of the center frequency can be less than -20 dB. It should be understood that if there is no additional explanation, when the antenna / radiator mentioned in this application generates "the first / second... resonance", among them, the first resonance should be the fundamental mode resonance generated by the antenna / radiator, or rather, the resonance with the lowest frequency generated by the antenna / radiator. It should be understood that the antenna / radiator can generate one or more antenna modes according to the specific design, and each antenna mode can correspondingly generate a fundamental mode resonance.
[0069] Resonant Frequency Band: The range of the resonant frequency is the resonant frequency band, and the return loss characteristic of any frequency point within the resonant frequency band can be less than -6 dB or -5 dB.
[0070] Communication Frequency Band / Operating Frequency Band: No matter what type of antenna, it always operates within a certain frequency range (bandwidth). For example, an antenna supporting Band 40 has an operating frequency band including frequencies in the range of 2300 MHz to 2400 MHz, or rather, the operating frequency band of this antenna includes Band 40. The frequency range that meets the index requirements can be regarded as the operating frequency band of the antenna.
[0071] The resonant frequency band and the operating frequency band can be the same or can partially overlap. In one embodiment, one or more resonant frequency bands of the antenna can cover one or more operating frequency bands of the antenna.
[0072] Electrical Length: It can refer to the ratio of the physical length (i.e., mechanical length or geometric length) to the wavelength of the transmitted electromagnetic wave. The electrical length can satisfy the following formula:
[0073]
[0074] where L is the physical length and λ is the wavelength of the electromagnetic wave.
[0075] Wavelength: Or the operating wavelength, which can be the wavelength corresponding to the center frequency of the resonant frequency or the center frequency of the operating frequency band supported by the antenna. For example, assuming the center frequency of the B1 uplink frequency band (resonant frequency is 1920 MHz to 1980 MHz) is 1955 MHz, then the operating wavelength can be the wavelength calculated using this frequency of 1955 MHz. Not limited to the center frequency, the "operating wavelength" can also refer to the wavelength corresponding to a non - center frequency of the resonant frequency or the operating frequency band.
[0076] It should be understood that the wavelength of the radiated signal in air can be calculated as follows: (air wavelength, or vacuum wavelength) = speed of light / frequency, where the frequency is the frequency of the radiated signal (MHz), and the speed of light can be taken as 3×10^8 m / s. The wavelength of the radiated signal in a medium can be calculated as follows: Among them, ε is the relative dielectric constant of the medium. The wavelength in the embodiments of the present application generally refers to the medium wavelength, which can be the medium wavelength corresponding to the center frequency of the resonant frequency, or the medium wavelength corresponding to the center frequency of the operating frequency band supported by the antenna. For example, assuming that the center frequency of the B1 uplink frequency band (resonant frequency is 1920 MHz to 1980 MHz) is 1955 MHz, the wavelength can be the medium wavelength calculated using the frequency of 1955 MHz. Not limited to the center frequency, the "medium wavelength" can also refer to the medium wavelength corresponding to the non-center frequency of the resonant frequency or the operating frequency band. For ease of understanding, the medium wavelength mentioned in the embodiments of the present application can be simply calculated by the relative dielectric constant of the medium filled on one side or multiple sides of the radiator.
[0077] Those skilled in the art can understand that efficiency is generally expressed as a percentage, and there is a corresponding conversion relationship between it and dB. The closer the efficiency is to 0 dB, the better the efficiency of the antenna is characterized.
[0078] Ground (GND): It can generally refer to at least a part of any ground layer, ground plane, or ground metal layer in an electronic device (such as a mobile phone), or at least a part of any combination of the above ground layer, ground plane, or ground component. "Ground" can be used for grounding components in an electronic device. In one embodiment, "ground" can be the ground layer of the circuit board of the electronic device, or the ground plane formed by the middle frame of the electronic device or the ground metal layer formed by the metal film under the screen. In one embodiment, the circuit board can be a printed circuit board (PCB), such as an 8-layer, 10-layer, or 12 - 14-layer board with 8, 10, 12, 13, or 14 layers of conductive material, or components separated and electrically insulated by dielectric layers or insulating layers such as fiberglass, polymer, etc. In one embodiment, the circuit board includes a dielectric substrate, a ground layer, and a trace layer, and the trace layer and the ground layer are electrically connected through vias. In one embodiment, components such as a display, a touch screen, an input button, a transmitter, a processor, a memory, a battery, a charging circuit, a system on chip (SoC) structure, etc. can be mounted on the circuit board or connected to the circuit board; or electrically connected to the trace layer and / or the ground layer in the circuit board. For example, a radio frequency source is arranged on the trace layer.
[0079] Any of the above ground layers, or ground plates, or ground metal layers is made of a conductive material. In one embodiment, the conductive material can be any one of the following materials: copper, aluminum, stainless steel, brass and their alloys, copper foil on an insulating substrate, aluminum foil on an insulating substrate, gold foil on an insulating substrate, silver-plated copper, silver-plated copper foil on an insulating substrate, silver foil on an insulating substrate, and tin-plated copper, cloth impregnated with graphite powder, a substrate coated with graphite, a copper-plated substrate, a brass-plated substrate, and an aluminum-plated substrate. Those skilled in the art can understand that the ground layer / ground plate / ground metal layer can also be made of other conductive materials.
[0080] Grounding: It means achieving coupling with the above-mentioned ground / floor in any way. In one embodiment, grounding can be through physical grounding, such as achieving physical grounding (or called, physical ground) at specific positions on the frame through some structural members of the middle frame. In one embodiment, grounding can be through device grounding, such as grounding through devices such as capacitors / inductors / resistors connected in series or in parallel (or called, device ground).
[0081] Next, the technical solutions of the embodiments of the present application will be described in conjunction with the accompanying drawings.
[0082] As Figure 1 shown, the electronic device 10 may include: a cover 13, a display / display module 15, a printed circuit board (PCB) 17, a middle frame 19, and a rear cover 21. It should be understood that in some embodiments, the cover 13 may be a cover glass, or may be replaced with a cover made of other materials, such as a cover made of PET (Polyethylene terephthalate) material, etc.
[0083] Among them, the cover 13 can be arranged closely against the display module 15, and can mainly be used to protect the display module 15 and prevent dust.
[0084] 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., and the embodiments of the present application do not limit this.
[0085] The middle frame 19 mainly plays a supporting role for the whole machine. Figure 1As shown in the figure, the PCB 17 is disposed between the middle frame 19 and the rear cover 21. It should be understood that in one embodiment, the PCB 17 can also be disposed between the middle frame 19 and the display module 15, and the embodiments of the present application do not limit this. Among them, the printed circuit board PCB 17 can use a flame-retardant material (FR-4) dielectric board, or a Rogers dielectric board, or a mixed dielectric board of Rogers and FR-4, and so on. Here, FR-4 is a code for a flame-retardant material grade, and the Rogers dielectric board is a high-frequency board. Electronic components are carried on the PCB 17, for example, radio frequency chips, etc. In one embodiment, a metal layer can be provided on the printed circuit board PCB 17. This metal layer can be used for grounding the electronic components carried on the printed circuit board PCB 17, and can also be used for grounding other components, such as a bracket antenna, a frame antenna, etc. This metal layer can be called a floor, or a ground plane, or a ground layer. In one embodiment, this metal layer can be formed by etching metal on the surface of any layer of dielectric board in the PCB 17. In one embodiment, the metal layer for grounding can be disposed on the side of the printed circuit board PCB 17 close to the middle frame 19. In one embodiment, the edge of the printed circuit board PCB 17 can be regarded as the edge of its ground layer. In one embodiment, the metal middle frame 19 can also be used for grounding the above-mentioned components. The electronic device 10 can also have other floors / ground planes / ground layers. As described above, details are not elaborated here.
[0086] Due to the compactness inside the electronic device, generally, floors / ground planes / ground layers are provided in the internal space within 0-2 mm from the inner surface of the frame (for example, the printed circuit board, the middle frame, the screen metal layer, the battery, etc. can all be regarded as part of the floor). In one embodiment, a dielectric is filled between the frame and the floor. The length and width of the rectangle formed by enclosing the inner surface contour of the filled dielectric can be simply regarded as the length and width of the floor; or the length and width of the rectangle formed by enclosing the contour formed by superimposing all the conductive parts inside the frame can be regarded as the length and width of the floor.
[0087] Among them, the electronic device 10 can also include a battery (not shown in the figure). The battery can be disposed between the middle frame 19 and the rear cover 21, or can be disposed between the middle frame 19 and the display module 15, and the embodiments of the present application do not limit this. In some embodiments, the PCB 17 is divided into a main board and a sub-board, and the battery can be disposed between the main board and the sub-board. Among them, the main board can be disposed between the middle frame 19 and the upper edge of the battery, and the sub-board can be disposed between the middle frame 19 and the lower edge of the battery.
[0088] The electronic device 10 may further include a frame 11, which may be formed of a conductive material such as metal. The frame 11 may be disposed between the display module 15 and the rear 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 fix the display module 15. In one implementation, the frame 11 made of a conductive material may be directly used as the conductive frame of the electronic device 10, for example, to form the appearance of a metal frame, which is suitable for metal industrial design (ID). In one implementation, the outer surface of the frame 11 may be a conductive material, such as a metal material, so as to form the appearance of a metal frame. In these implementations, the conductive portion of the frame 11 may be used as the antenna radiator of the electronic device 10.
[0089] In another implementation, the outer surface of the frame 11 may also be a non-conductive material, such as plastic, to form the appearance of a non-metal frame, which is suitable for non-metal ID. In one implementation, the inner surface of the frame 11 may include a conductive material, such as a metal material. In this implementation, the conductive portion of the frame 11 may be used as the antenna radiator of the electronic device 10. It should be understood that the radiator provided on the inner surface of the frame 11 (or the conductive material on the inner surface) is arranged in conformity with the non-conductive material of the frame 11 to facilitate antenna radiation, and both the conductive material and the non-conductive material should be regarded as part of the frame 11.
[0090] It should be understood that the frame 11 may have insulating gaps, and the conductor portion of the frame between two insulating gaps or between an insulating gap and a ground point serves as a radiator, thereby forming a frame antenna. Among them, 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 a non-metal material (insulating material). And this gap is visible on the appearance surface. When the outer surface of the frame 11 is a non-conductive material, the insulating gap can be understood as a gap spaced between the conductor portions inside the frame 11, and this gap may be filled with a non-metal material (insulating material), or may not be filled with a non-metal material and be filled with air. And this gap is not visible on the appearance surface.
[0091] The middle frame 19 may include the frame 11. The middle frame 19 including the frame 11, as an integral part, can support the electronic components in the whole machine. The cover plate 13 and the rear cover 21 are respectively covered along the upper and lower edges of the frame to form the outer shell or housing of the electronic device. In one embodiment, the cover plate 13, the rear cover 21, the frame 11, and / or the middle frame 19 may be collectively referred to as the outer shell or housing of the electronic device 10. It should be understood that the "outer shell or housing" may be used to refer to a part or all of any one of the cover plate 13, the rear cover 21, the frame 11, or the middle frame 19, or refer to a part or all of any combination of the cover plate 13, the rear cover 21, the frame 11, or the middle frame 19.
[0092] The frame 11 can at least partially serve as an antenna radiator to receive / transmit radio frequency signals. There can be a gap between this part of the frame serving as the radiator and the other parts of the middle frame 19, thus ensuring a good radiation environment for the antenna radiator. In one embodiment, the middle frame 19 can be provided with apertures at this part of the frame serving as the radiator to facilitate the radiation of the antenna.
[0093] Alternatively, the frame 11 may not be regarded as part of the middle frame 19. In one embodiment, the frame 11 can be connected to and integrally formed with the middle frame 19. In another embodiment, the frame 11 can include a protruding member extending inward to connect with the middle frame 19. For example, it can be connected by means of a spring piece, a screw, welding, etc. The protruding member of the frame 11 can also be used to receive a feeding signal, so that at least a part of the frame 11 serves as an antenna radiator to receive / transmit radio frequency signals. There can be a gap 42 between this part of the frame serving as the radiator and the middle frame 19, thus ensuring a good radiation environment for the antenna radiator and enabling the antenna to have a good signal transmission function.
[0094] Among them, the rear cover 21 can be a rear cover made of a metal material; it can also be a rear cover made of a non-conductive material, such as a glass rear cover, a plastic rear cover and other non-metal rear covers; it can also be a rear cover made of both conductive and non-conductive materials. In one embodiment, the rear cover 21 including a conductive material can replace the middle frame 19 and, together with the frame 11, serve as an integral part to support the electronic devices in the whole machine.
[0095] In one embodiment, the middle frame 19, and / or the conductive part of the rear cover 21, can serve as the reference ground of the electronic device 10. Among them, the frame 11, the PCB 17, etc. of the electronic device can be grounded by electrically connecting with the middle frame.
[0096] The antenna of the electronic device 10 can also be arranged inside the frame 11. When the frame 11 of the electronic device 10 is made of a non-conductive material, the antenna radiator can be located inside the electronic device 10 and arranged along the frame 11. For example, the antenna radiator is arranged close to the frame 11 to minimize the volume occupied by the antenna radiator and be closer to the outside of the electronic device 10 to achieve a better signal transmission effect. It should be noted that the antenna radiator being arranged close to the frame 11 means that the antenna radiator can be arranged closely against the frame 11 or close to the frame 11. For example, there can be a certain small gap between the antenna radiator and the frame 11.
[0097] The antenna of the electronic device 10 can also be arranged inside the housing, such as a bracket antenna, a millimeter wave antenna, etc. Figure 1(not shown in the figure). The clearance of the antenna disposed within the housing can be obtained by a slit / aperture on any one of the middle frame, and / or the side frame, and / or the rear cover, and / or the display screen, or by a non-conductive gap / aperture formed between any several of them. The setting of the clearance of the antenna can ensure the radiation characteristics of the antenna. It should be understood that the clearance of the antenna can be a non-conductive area formed by any conductive component within the electronic device 10, and the antenna radiates signals to the external space through this non-conductive area. In one embodiment, the form of the antenna 40 can be an antenna form based on a flexible printed circuit (FPC), an antenna form based on laser-direct-structuring (LDS), or a microstrip disk antenna (MDA), etc. In one embodiment, the antenna can also adopt a transparent structure embedded inside the screen of the electronic device 10, such that the antenna is a transparent antenna unit embedded inside the screen of the electronic device 10.
[0098] Figure 1 Only some components included in the electronic device 10 are schematically shown, and the actual shape, actual size, and actual structure of these components are not limited by Figure 1 the limitations.
[0099] 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 regarded as the front surface, the surface where the rear cover is located can be regarded as the back surface, and the surface where the side frame is located can be regarded as the side surface.
[0100] It should be understood that in the embodiments of the present application, when it is considered that the user holds the electronic device (usually vertically and facing the screen), the orientation of the electronic device has a top, a bottom, a left side, and a right side. It should be understood that in the embodiments of the present application, when it is considered that the user holds the electronic device (usually vertically and facing the screen), the orientation of the electronic device has a top, a bottom, a left side, and a right side.
[0101] Figure 2 is a schematic diagram of an electronic device 10 provided by an embodiment of the present application.
[0102] As Figure 2 shown, the conductive side frame 11 of the electronic device 10 can have a first position 101, a second position 102, and a grounding point 103 located between the first position 101 and the second position 102. In one embodiment, the side frame 11 respectively opens a first slit and a second slit at the first position 101 and the second position 102, and is coupled and connected to the ground plane at the third position 103.
[0103] The radiator 105 of the antenna 100 is the conductive part of the side frame 11 between the first position 101 and the second position 102.
[0104] When the electronic device 10 conducts satellite communication through the antenna 100 (with the antenna 100 serving as a satellite communication antenna), a very high transmission power is required. To prevent high-power electrical signals from being injected into the RF channels of antennas disposed adjacent to the antenna 100, which may damage the electronic components in the RF channels or interfere with the received signals, generally, when the antenna 100 is operating, the adjacent antennas do not operate.
[0105] When the electronic device 10 conducts satellite communication, it cannot communicate through the adjacent antennas, and the electronic device 10 loses some functions, which causes inconvenience to users in use. For example, in existing designs, a navigation antenna (for example, the operating frequency band includes some frequency bands in GPS) usually multiplexes at least part of the radiator 105 as a radiator (for example, the conductive part of the frame 11 between the first position 101 and the ground point 103). The power of the signal received by the navigation antenna is only -130 dB, while the transmission power of the satellite communication antenna is about 30 dB. Since the navigation antenna multiplexes part of the radiator of the satellite communication antenna to generate radiation, the isolation between the satellite navigation antenna and the satellite communication antenna is poor. When the two antennas operate simultaneously, the transmission signal of the high-power satellite communication antenna will be fed into the RF circuit of the satellite navigation antenna, causing damage to the electronic components in the RF circuit. Therefore, the satellite navigation antenna and the satellite communication antenna (antenna 100) cannot operate simultaneously. And since the satellite navigation antenna is in a non-operating state when the satellite communication antenna (antenna 100) is operating, the electronic device 10 cannot perform navigation simultaneously when conducting satellite communication.
[0106] An embodiment of the present application provides an electronic device, which includes a first antenna and a second antenna. Both the first antenna and the second antenna use the conductive part of the frame of the electronic device as a radiator. Among them, the operating frequency band of the first antenna includes the satellite communication frequency band, and the operating frequency band of the second antenna includes the satellite navigation frequency band. When the electronic device conducts satellite communication through the first antenna, the electronic device can also perform satellite navigation through the second antenna simultaneously, improving the user experience when conducting satellite communication.
[0107] Figure 3 It is a schematic diagram of an electronic device 10 provided by an embodiment of the present application.
[0108] As Figure 3 shown, the electronic device 10 includes a frame 11, a first antenna 210, a second antenna 220, and a ground plane 200.
[0109] Among them, the frame 11 includes a first position 201, a second position 202, a third position 203, and a fourth position 204 arranged in sequence.
[0110] The first antenna 210 includes a first radiator 211 and a first modem 212.
[0111] The first radiator 211 is a conductive part of the frame 11 between the first position 201 and the second position 202. At least part of the first radiator 211 is spaced apart from the floor 200. The first modem 212 is coupled to the first radiator 211.
[0112] It should be understood that in the embodiments of the present application, the modem is used to process the electrical signals transmitted or received by the corresponding antenna. Processing the electrical signals can be understood as modulating the electrical signals transmitted by the feeding circuit, for example, up-converting, or modulating the electrical signals received by the antenna, for example, down-converting. For the sake of brevity of discussion, they will not be elaborated one by one.
[0113] The second antenna 220 includes a second radiator 221 and a second modem 222.
[0114] The second radiator 221 is a conductive part of the frame 11 between the third position 203 and the fourth position 204. At least part of the second radiator 221 is spaced apart from the floor 200. The second modem 222 is coupled to the second radiator 221. The first modem 212 is coupled to the second modem 222.
[0115] The operating frequency band of the first antenna 210 includes a satellite communication frequency band. The operating frequency band of the second antenna 220 includes a non-satellite communication frequency band.
[0116] In one embodiment, the first frequency band may include a transmission frequency band and / or a reception frequency band in satellite communication. For example, in the Tiantong satellite system, the first frequency band may include 1980 MHz - 2010 MHz (transmission frequency band), 2170 MHz - 2200 MHz (reception frequency band). In the Beidou satellite system, the first frequency band may include 1610 MHz - 1626.5 MHz (transmission frequency band), 2483.5 MHz - 2500 MHz (reception frequency band). Or, it can also be applied to other satellite communication systems, and the embodiments of the present application do not limit this.
[0117] In one embodiment, when the first antenna 210 operates in the Tiantong satellite system (the operating frequency band of the first antenna 210 includes at least part of the frequency bands in the Tiantong satellite system), the electronic device 10 can perform voice communication through the first antenna 210. In one embodiment, when the first antenna 210 operates in the Beidou satellite system (the operating frequency band of the first antenna 210 includes at least part of the frequency bands in the Beidou satellite system), the electronic device 10 can send or receive pictures or short messages through the first antenna 210.
[0118] It should be understood that for the sake of simplicity of discussion, in the embodiments of the present application, the satellite communication performed by the electronic device 10 can be understood as that the electronic device 10 can send or receive pictures or short messages to / from a satellite using the first antenna 210, or the electronic device 10 can perform voice communication via the satellite using the first antenna 210.
[0119] In one embodiment, the second frequency band may include a non-satellite communication frequency band. In one embodiment, the second frequency band may include a satellite navigation frequency band. For example, the GPS frequency band (L1 frequency band, L2 frequency band or L5 frequency band). In one embodiment, the second frequency band may include a short-range communication frequency band. For example, the WiFi frequency band, the BT frequency band. In one embodiment, the second frequency band may also include at least some frequency bands in the cellular network, for example, at least some frequency bands in the low frequency band (698 MHz - 960 MHz), at least some frequency bands in the medium frequency band (1710 MHz - 2170 MHz), at least some frequency bands in the high frequency band (2300 MHz - 2690 MHz), at least some frequency bands in sub 6G.
[0120] The first modem 212 sends a first signal to the second modem 222. The first signal is used to instruct the first antenna 210 to send a signal at a first moment. The second modem 222 processes a second signal received by the second antenna 220 at the first moment according to the first signal. In one embodiment, the second modem 222 deletes or replaces the second signal received by the second antenna 220 at the first moment according to the first signal.
[0121] It should be understood that according to the technical solution provided by the embodiments of the present application, the radiators of the first antenna 210 and the second antenna 220 are different (the first radiator 211 and the second radiator 221 do not overlap, and the first antenna 210 and the second antenna 220 do not reuse the radiator), and there is good isolation between the first antenna 210 and the second antenna 220. When the first antenna 210 and the second antenna 220 work simultaneously, the first antenna 210 transmitting a signal will not damage the electronic components in the RF circuit of the second antenna 220.
[0122] Moreover, when the first antenna 210 and the second antenna 220 work simultaneously, the first modem 212 sends a first signal to the second modem 222. The second modem 222 determines that the first antenna 210 sends a signal at the first moment through the first signal, and the second modem 222 processes the second signal received by the second antenna 220 at the first moment, so that the second antenna 220 is not affected by the signal sent by the first antenna 210, and the first antenna 210 and the second antenna 220 can work simultaneously.
[0123] In one embodiment, the frame 11 includes a first side 131 and a second side 132 that intersect at an angle, and the length of the first side is less than the length of the second side 132. In one embodiment, the first side 131 may be the top side of the electronic device 10.
[0124] In one embodiment, the second position 202 and the third position 203 are located on the first side 131. In one embodiment, at least part of the radiators of the first radiator 211 and the second radiator 221 may be located on the first side 131.
[0125] It should be understood that at least part of the radiators of the first radiator 211 and the second radiator 221 being located on the first side 131 can facilitate the radiation of the first antenna 210 and the second antenna 220 towards the top of the electronic device 10 (the maximum radiation direction of the radiation pattern is towards the top of the electronic device, for example, the y direction). When the first antenna 210 is a satellite communication antenna, the maximum radiation direction is towards the top of the electronic device 10, which is convenient for satellite acquisition (establishing a communication connection with a satellite) when the electronic device 10 performs satellite communication. When the second antenna 220 is a satellite navigation antenna, it is convenient for the electronic device 10 to achieve precise positioning.
[0126] In one embodiment, the frame 11 respectively forms a first insulating gap, a second insulating gap, and a third insulating gap at the first position 201, the second position 202, and the third position 203. The frame 11 is coupled to the floor 200 at the fourth position 204.
[0127] In one embodiment, the frame 11 respectively forms a first insulating gap, a second insulating gap, and a third insulating gap at the first position 201, the second position 202, and the fourth position 204, as shown in (a) of Figure 4 . The frame 11 is coupled to the floor 200 at the third position 203.
[0128] In one embodiment, the second position 202 and the third position 203 are the same (overlap), and the first radiator 211 and the second radiator 221 are adjacent, as shown in (b) of Figure 4 . The frame 11 respectively forms a first insulating gap and a second insulating gap at the first position 201 and the second position 202 (the third position 203). The frame 11 is coupled to the floor 200 at the fourth position 204.
[0129] It should be understood that the embodiments of the present application do not limit the boundary conditions of the first radiator 211 and the second radiator 221 (for example, the frame 11 has an insulating gap or is coupled to the floor 200 at the first position 201, the second position 202, the third position 203, or the fourth position 204), and do not limit the positions of the first position 201, the second position 202, the third position 203, and the fourth position 204 on the frame 11, which can all be adjusted according to actual production or design. The above embodiments are only for illustration and will not be elaborated one by one.
[0130] In one embodiment, the isolation between the first antenna 210 and the second antenna 220 is greater than or equal to 20 dB. In one embodiment, the isolation between the first antenna 210 and the second antenna 220 is greater than or equal to 25 dB.
[0131] It should be understood that as the isolation between the first antenna 210 and the second antenna 220 increases, when the first antenna 210 is operating, the second antenna 220 has better radiation characteristics.
[0132] In one embodiment, the second modem 222 deletes the second signal received by the second antenna 220 at the first moment according to the first signal, and further includes: when the first moment corresponds to the first time slot in a plurality of first sub-frames, the second modem deletes the signals stored in the plurality of first time slots, and the second modem synthesizes the plurality of first sub-frames into a second sub-frame.
[0133] As Figure 5 shown, when the first antenna sends a signal at the first moment (for example, the first moment is from time slot 4 to time slot 6 in sub-frame 1 and from time slot 1 to time slot 3 in sub-frame 2), the second modem deletes the signals received by the second antenna in time slot 4 to time slot 6 in sub-frame 1 and from time slot 1 to time slot 3 in sub-frame 2. Since there will be some duplicate information in the signals received by the second antenna stored in adjacent sub-frames, therefore, the sub-frames corresponding to the first moment (sub-frame 1 and sub-frame 2) can be synthesized into a new sub-frame, and this sub-frame will not lose information. Therefore, the second antenna can work simultaneously with the first antenna without affecting the integrity of the signals received by the second antenna, so that users can perform satellite communication without losing other functions, such as satellite navigation.
[0134] It should be understood that the first moment described in the embodiments of the present application can be understood as all time slots corresponding to the first antenna when it is sending. For example, the first moment can include multiple time slots within the same sub-frame, or different time slots in multiple sub-frames, and the embodiments of the present application do not limit this.
[0135] In one embodiment, the second modem 222 replaces the second signal received by the second antenna 220 at the first moment according to the first signal, including: the second modem replaces the second signal with a third signal, where the third signal is a default signal, or the third signal is a signal stored in the time slot corresponding to the first moment in the second sub-frame. The second sub-frame is adjacent to the first sub-frame, and the first sub-frame includes the first moment.
[0136] As Figure 6 shown, when the first antenna transmits a signal at the first moment (for example, the first moment is time slots 4 to 6 in sub-frame 1), the second modem replaces the signal stored in time slots 4 to 6 in sub-frame 1 with the signal stored in the corresponding time slots (time slots 4 to 6 in sub-frame 2) in the adjacent sub-frame 2, and sub-frame 1 does not lose information. Therefore, the second antenna can work simultaneously with the first antenna without affecting the integrity of the information received by the second antenna, so that the user can perform other functions, such as satellite navigation, without losing them when conducting satellite communication.
[0137] It should be understood that in the Figure 6 scheme shown, only the signal stored in time slots 4 to 6 in sub-frame 2 is taken as an example for the third signal. The third signal can also be the signal stored in time slots 4 to 6 in [sub-frame X], or the third signal can also be a preset default signal. The embodiments of the present application do not limit this.
[0138] In the above embodiment, only taking the example that the first antenna 210 transmits a signal and the second antenna 220 receives a signal simultaneously at the first moment, the first modem 212 sends the first signal to the second modem 222, and the second modem 222 deletes or replaces the second signal received by the second antenna 220 at the first moment according to the first signal. In one embodiment, the second modem 222 controls the second antenna 220 to receive a fourth signal at the second moment, where the first moment and the second moment are different time slots in the first sub-frame.
[0139] It should be understood that as Figure 7 shown, in the first sub-frame, the first antenna transmits a signal at the first moment (for example, time slots 1, 2, 4, 5 in sub-frame 1), and the second antenna receives a signal at the second moment (for example, time slots 7, 8 in sub-frame 2). Since the second antenna does not receive a signal at the first moment, the second antenna is not affected by the signal transmitted by the first antenna, and the first antenna and the second antenna can work simultaneously in the first sub-frame.
[0140] In one embodiment, the first antenna receives a fifth signal at the second moment. It should be understood that the first antenna and the second antenna can receive signals in the same time slot, and there will be no mutual interference between the first antenna and the second antenna.
[0141] In one embodiment, the second modem 222 controls the circuit between the second modem 222 and the second radiator 221 to be in an isolated state at a first moment according to the first signal, reducing the influence of the transmitted signal of the first antenna 210 on the radio frequency circuit of the second antenna 220. Herein, the circuit being in an isolated state can be understood as that the active devices in the circuit are not powered on (not supplied with power), and the switches are in an off state.
[0142] Figure 8 It is a schematic diagram of an electronic device 10 provided by an embodiment of the present application.
[0143] As Figure 8 shown, the electronic device 10 includes a baseband chip 223.
[0144] Among them, the baseband chip 223 is coupled to the second radiator 221. When the electronic device 10 communicates through the first antenna 210, the baseband chip 223 is used to delete or replace the first signal, where the first signal is the signal received by the second antenna 220 and the signal is in a saturated state.
[0145] It should be understood that for the received signal, the power of the received signal is small. For example, when the operating frequency band of the second antenna 220 includes the satellite navigation frequency band, the power of the received signal is only about -130 dB. When the signal transmitted in the baseband chip 223 is in a saturated state (the saturated state can be understood as that the power of the signal is greater than the threshold, for example, 0 dB), it can be considered that the abnormal power of the signal is affected by the high-power signal transmitted by the first antenna 210, and part of the power is transmitted to the radio frequency circuit of the second antenna 220, then the part of the signal in the saturated state is deleted. The baseband chip 223 processes the signal received by the second antenna 220 in the saturated state, so that the second antenna 220 is not affected by the signal transmitted by the first antenna 210, and the first antenna 210 and the second antenna 220 can work simultaneously.
[0146] In one embodiment, the baseband chip 223 is used to replace the first signal, and further includes: the baseband chip 223 replaces the first signal with a second signal, where the second signal is a default signal, or the second signal is the signal stored in the time slot corresponding to the time slot storing the first signal in the second sub-frame, the second sub-frame is adjacent to the first sub-frame, and the first sub-frame includes the time slot storing the first signal.
[0147] In one embodiment, the baseband chip 223 is used to delete the first signal, and further includes: when the first moment corresponds to multiple first sub-frames, the baseband chip 223 deletes the first signal in the multiple first sub-frames, and the baseband chip 223 combines the multiple first sub-frames into a second sub-frame.
[0148] It should be understood that the baseband chip 223 is used to delete or replace the first signal and in the above embodiment ( Figure 5 andFigure 6 Similarly, the second modem 222 deletes or replaces the second signal, which will not be elaborated one by one.
[0149] For the sake of brevity of discussion, Figure 8 the first antenna 210 and the second antenna 220 shown in Figure 3 the first antenna 210 and the second antenna 220 shown in will not be elaborated one by one for the similar parts. For example, the similar parts include the position of the first radiator 211; the position of the second radiator 221; the relative position of the first radiator 211 and the second radiator 221; the operating frequency bands of the first antenna and the second antenna; the isolation between the first antenna and the second antenna; deleting or replacing signals; and so on.
[0150] In one embodiment, the first antenna 210 includes a first modem 212. The second antenna 220 includes a second modem 222. The first modem 212 and the second modem 222 are not directly coupled, as shown in Figure 8 wherein, not being directly coupled can be understood as that there is no direct communication interface between the first modem 212 and the second modem 222, and there is also a coupling connection between the first modem 212 and the second modem 222 by at least one chip.
[0151] In one embodiment, the electronic device 10 may further include an application processor (AP) 230. The AP 230 is coupled to the baseband chip 223. In one embodiment, the AP 230 sends a third signal to the baseband chip 223, and the third signal is used to instruct the electronic device 10 to communicate through the first antenna 210. In one embodiment, the first port of the AP 230 is coupled to the first modem 212, and the second port is coupled to the second modem 222. In one embodiment, the baseband chip 223 is used to process the first signal after receiving the third signal.
[0152] The first modem 212 and the second modem 222 can be used to send the working states of the first antenna 210 and the second antenna 220 to the AP, such as the operating frequency, the transmitting power, etc.
[0153] In one embodiment, the first modem 212 and the second modem 222 are coupled, as shown in Figure 9As shown. There is at least one circuit between the first modem 212 and the second modem 222 without a chip. In one embodiment, the first modem 212 sends a fourth signal to the second modem, and the fourth signal is used to indicate that the first antenna 210 sends a signal at the first moment. The second modem 222 sends a fifth signal to the baseband chip 223, and the fifth signal is used to indicate that the electronic device 10 communicates through the first antenna 210 at the first moment. In one embodiment, the baseband chip 223 is used to process the first signal after receiving the fifth signal.
