An electronic device, an interface display method, a medium, and a program product.

[0001] This application claims priority to Chinese Patent Application No. 202510339538.3, filed on March 20, 2025, entitled "An Electronic Device, Interface Display Method, Medium and Program Product", and Chinese Patent Application No. 202511881383.2, filed on December 12, 2025, entitled "An Electronic Device, Interface Display Method, Medium and Program Product", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electronic equipment technology, and in particular to an electronic device, an interface display method, a medium, and a program product. Background Technology

[0003] Integrating walkie-talkie functionality into portable electronic devices such as mobile phones, watches, and tablets can meet users' communication needs in special environments (such as no network or short distances).

[0004] Currently, the antennas in mobile phones and other electronic devices mainly operate at frequencies above 600MHz. How to implement walkie-talkie functionality in ultra-low frequency bands (e.g., 400-410MHz) in electronic devices while ensuring antenna performance is an urgent problem to be solved. Summary of the Invention

[0005] To address the aforementioned technical problems, embodiments of this application provide an electronic device, an interface display method, a medium, and a program product.

[0006] In a first aspect, embodiments of this application provide an electronic device, including: a housing; an antenna including a radiator and a feed point, the antenna being used for walkie-talkie communication of the electronic device, the feed point being coupled to the radiator and used to feed in radio frequency signals of the operating frequency band of the walkie-talkie communication; and a display screen being used to display a first interface when the electronic device enters walkie-talkie mode, the first interface including guidance information, the guidance information being used to guide the user to contact a preset area of ​​the housing.

[0007] Based on the above scheme, when the electronic device enters the walkie-talkie mode (e.g., the antenna operates at 400-410MHz), the first interface is displayed on the screen. The first interface guides the user's grip on the electronic device, causing the user to contact a preset area on the casing. This can improve the radiation efficiency of the antenna in walkie-talkie mode, thereby improving communication performance.

[0008] In some possible implementations, the preset area corresponds to the location of the radiator. That is, by guiding the user to the location of the radiator on the electronic device through the first interface, the antenna radiation efficiency in walkie-talkie mode can be improved, thereby enhancing communication performance.

[0009] In some possible implementations, the preset area corresponds to one end of the electronic device along its length, and this end is farther from the feed point of the radiator than the other end of the electronic device along its length. Furthermore, the radiator is electrically connected to the ground. That is, guiding the user to contact the end of the electronic device farther from the radiator via the first interface can also improve the antenna radiation efficiency in walkie-talkie mode, thereby enhancing communication performance.

[0010] In some possible implementations, the antenna is used to operate in the first operating frequency band; after the electronic device enters the walkie-talkie mode, the antenna is used to operate in the second operating frequency band corresponding to the walkie-talkie mode, which is lower than the first operating frequency band.

[0011] It is understandable that electronic devices can reuse existing antennas to achieve walkie-talkie communication. For example, if the main operating frequency band of the existing antenna is the first operating frequency band, after the electronic device enters the walkie-talkie mode, the antenna is used to operate on the second operating frequency band corresponding to the walkie-talkie mode. In this way, the existing antenna can be reused directly without the need to deploy additional antennas for walkie-talkie communication, thereby improving the antenna reuse rate and saving internal space of the electronic device.

[0012] In some possible implementations, the electrical length of the antenna can be one-quarter of the wavelength corresponding to the first operating frequency band. Therefore, the antenna has good performance in the first operating frequency band, but poor performance in the second operating frequency band. Therefore, by guiding the user to contact a preset area on the housing, the performance of the antenna in the second operating frequency band can be improved.

[0013] In some possible implementations, the first operating frequency band is in the range of 699–960 MHz. Correspondingly, the physical length of the radiator is 4–11 cm.

[0014] It is understandable that antennas in the 699–960 MHz band are common in electronic devices. Therefore, antennas in this frequency band can be reused for walkie-talkie communication, which can expand the applicability of integrating walkie-talkie functions into electronic devices.

[0015] It should be noted that this application does not limit the operating frequency band of the reused antenna.

[0016] In some possible implementations, the antenna also includes a first matching circuit and a second matching circuit, wherein the radiator and the first matching circuit are used to operate in a first operating frequency band, and the radiator and the second matching circuit are used to operate in a second operating frequency band.

[0017] It is understandable that through the first matching circuit and the second matching circuit, electronic devices can achieve efficient radiation and reception performance in two different operating frequency bands. This not only improves the radiation efficiency and signal quality of the antenna, but also enhances the flexibility and compatibility of its frequency band switching.

[0018] In some possible implementations, at least a portion of the radiator extends along a first direction, which is either the length or width direction of the electronic device, and a preset region is aligned with the point of maximum current of the radiator in a second direction, which is perpendicular to the first direction.

[0019] It is understandable that human contact with or proximity to an antenna can increase the antenna aperture (the effective size for receiving or transmitting electromagnetic waves) and also cause losses in antenna radiation. However, when the human body contacts or is close to the point of maximum current of the radiator, the benefits of increasing the antenna aperture can outweigh the losses caused by the human body in the radiation. The combined effect can improve antenna performance. Therefore, when an electronic device enters walkie-talkie mode, the first interface can guide the user to contact the preset area on the outer casing corresponding to the point of maximum current of the radiator, which helps to improve antenna performance in walkie-talkie mode.

[0020] In some possible implementations, the radiator includes spaced grounding points and feed points, with the grounding points located at one end of the radiator's extension direction, and a preset area corresponding to the grounding point.

[0021] It is understandable that if one end of the radiator includes a grounding point, then the grounding point is the point of maximum current. Therefore, electronic devices can guide users to contact the grounding point through the first interface to improve antenna performance in walkie-talkie mode.

[0022] In some possible implementations, one end of the radiator along its extension direction is an open end, and the radiator also includes a feed point, with a preset region corresponding to the feed point.

[0023] It is understandable that if one end of the radiator is an open end, then the feed point is the point of maximum current. Therefore, electronic devices can guide users to contact the feed point through the first interface to improve antenna performance in walkie-talkie mode.

[0024] In some possible implementations, the preset region is closer to the bottom of the electronic device along its length than the top of the electronic device along its length.

[0025] It is understandable that a suitable antenna can generally be selected for reuse based on its position in the electronic device. For example, an antenna located at the bottom of the electronic device can be reused to realize the walkie-talkie function. In this way, when the electronic device is in walkie-talkie mode, the user is guided to touch the preset area at the bottom of the electronic device, which allows the user to hold the electronic device in a more comfortable and stable way.

[0026] In some possible implementations, the radiator includes a first side extending along the width direction of the electronic device and a second side extending along the length direction of the electronic device, with the first side and the second side connected to form a corner region of the radiator.

[0027] Accordingly, the preset area satisfies at least one of the following: the preset area corresponds to the corner area; the preset area is aligned with one end of the width direction of the first edge in the length direction; the preset area is aligned with one end of the length direction of the second edge in the width direction.

[0028] It is understandable that for radiators with different structures, the specific position where the human body contacts the radiator can improve the antenna performance. Therefore, based on the actual user's holding habits, a suitable radiator and its position can be selected, and the user can be guided to contact the preset area of ​​the corresponding position through the first interface.

[0029] In some possible implementations, one end of the first side along the width direction is the first end of the radiator, and one end of the second side along the length direction is the second end of the radiator. The first end is an open end, and the second end includes a feed point; or, the first end includes a feed point, and the second end is an open end; or, the first end includes a feed point, and the second end includes a ground point; or, the first end includes a ground point, and the second end includes a feed point; or, the first end includes feed points and ground points spaced apart, and the second end is an open end; or, the first end is an open end, and the second end includes feed points and ground points spaced apart.

[0030] It is understood that for different types of radiators, the specific location where the human body comes into contact with the radiator can improve the antenna performance. Therefore, this application does not limit the structure and form of the radiator.

[0031] In some possible implementations, the electronic device has two short sides arranged opposite each other along its length. One end of the electronic device along its length includes a short side portion of the electronic device. The short side portion includes an extension region extending from either of the two short sides toward the other short side. The ratio between the size of the extension region in the length direction and the size of the electronic device in the length direction is 1 / 10 to 1 / 4.

[0032] In some possible implementations, the outer casing is made of a metallic material, and at least a portion of the casing is used to form a radiator.

[0033] It is understandable that if at least part of the casing of an electronic device is a radiator, then when the user touches the casing, they are in direct contact with the radiator, which is more beneficial to the improvement of antenna performance. In this way, the electronic device can provide a better communication experience in walkie-talkie mode.

[0034] In some possible implementations, the preset area has patterned markings that guide the user to interact with it.

[0035] It is understandable that the electronic device's casing has patterned markings to guide the user to the area. These markings can be formed using methods such as laser marking, photolithography, or ink printing. This provides a more intuitive way for the user to access the location in walkie-talkie mode.

[0036] In some possible ways, the user manual of the electronic device, which is shipped or sold with the electronic device, may contain relevant instructions on the walkie-talkie function of the electronic device, such as prompting the user to touch the preset area of ​​the casing in walkie-talkie mode, or to adopt the grip posture provided in the specific embodiments of this application.

[0037] In some possible ways, the electronic device is a watch, and the radiator includes at least a portion of the watch's annular bezel.

[0038] The ring-shaped frame can be circular, rectangular, square, oval, or other shapes. It's understood that guiding the user to the watch's ring-shaped frame through the initial interface can improve the watch's antenna radiation efficiency in walkie-talkie mode, thereby enhancing communication performance.

[0039] In some possible configurations, the radiator comprises a complete annular border; or the radiator comprises a first portion of the annular border, wherein the annular border includes a first slit and a second slit, and the first portion is the part of the annular border between the first slit and the second slit.

[0040] It is understandable that for a radiator including a complete annular frame, guiding the user to touch any part of the annular frame of the watch can improve the antenna's radiation efficiency. For a radiator including the first part of the annular frame, guiding the user to touch the first part through a first interface can improve the antenna's radiation efficiency.

[0041] Secondly, embodiments of this application provide an interface display method applied to an electronic device. The method includes: when the electronic device enters a walkie-talkie mode, displaying a first interface, the first interface including guidance information for the user's holding posture, the guidance information being used to guide the user to contact a preset area of ​​the outer shell of the electronic device.

[0042] In some possible implementations, the guidance information includes one or more of the following: information to indicate the user's grip posture when touching the shell; information to indicate the user's arm posture when touching the shell; information to indicate the area of ​​the shell that the user is touching; and information to indicate the number of fingers that the user is touching the shell.

[0043] It is understandable that visual guidance information can be used to guide users to hold electronic devices (such as mobile phones) in a specific posture so that users can touch specific areas on the casing of the electronic device, or to guide users to touch the electronic device (such as watches) with a specific arm posture or number of fingers. This can provide clear and intuitive operation guidance for users, improve the ease of use of walkie-talkie functions, and thus achieve the goal of improving antenna radiation efficiency in walkie-talkie mode.

[0044] In some possible implementations, the guidance information includes at least one display element among text, images, and symbols.

[0045] Thirdly, embodiments of this application provide a readable storage medium that includes one or more programs. When the one or more programs are executed on an electronic device, the electronic device enables the interface display method described in the second aspect above.

[0046] Fourthly, embodiments of this application provide a program product that, when executed on an electronic device, enables the electronic device to implement the interface display method described in the second aspect above.

[0047] The technical effects of the second to fourth aspects mentioned above can be referred to the technical effects of the first aspect, and will not be repeated here. Attached Figure Description

[0104] The illustrative embodiments of this application include, but are not limited to, an electronic device, an interface display method, a medium, and a program product.

[0105] The following explains the terminology that may appear in the embodiments of this application.

[0106] Radiator: In an antenna, this is the device used to receive / transmit electromagnetic wave radiation. In some cases, the term "antenna" is narrowly defined as a radiator, which converts guided wave energy from the transmitter into radio waves, or converts radio waves into guided wave energy, for radiating and receiving radio waves. The modulated high-frequency current energy (or guided wave energy) generated by the transmitter is transmitted to the transmitting radiator via a feed line, where it is converted into electromagnetic wave energy of a specific polarization and radiated in the desired direction. The receiving radiator converts the electromagnetic wave energy of a specific polarization from a specific direction in space back into modulated high-frequency current energy, which is then transmitted to the receiver input via a feed line.

[0107] The radiator may include a conductor with a specific shape and size, such as a wire or sheet, and this application does not limit the specific shape. In one embodiment, the wire radiator may be simply referred to as a wire antenna. In one embodiment, the wire radiator may be implemented by a conductive frame, and may also be referred to as a frame antenna. In one embodiment, the wire radiator may be implemented by a support conductor, and may also be referred to as a support antenna. In one embodiment, the wire diameter (e.g., including thickness and width) of the wire radiator, or the radiator of the wire antenna, is much smaller than the wavelength (e.g., the wavelength of the medium) (e.g., less than 1 / 16 of the wavelength), and the length may be comparable to the wavelength (e.g., the wavelength of the medium) (e.g., the length is around 1 / 8 of the wavelength, or 1 / 8 to 1 / 4, or 1 / 4 to 1 / 2, or longer). The main forms of wire antennas include dipole antennas, half-wave dipole antennas, monopole antennas, loop antennas, and inverted F antennas (also known as IFA, Inverted F Antenna). For example, in a dipole antenna, each dipole antenna typically includes two radiating stubs, each fed from the feed end of the radiating stub by a feed section. For example, an IFA can be considered as a monopole antenna with an added ground path. An IFA has one feed point and one ground point, and is called an inverted-F antenna because its side view is inverted-F shaped. In one embodiment, the sheet radiator may include a microstrip antenna or a patch antenna, such as a planar inverted-F antenna (also known as a PIFA). In one embodiment, the sheet radiator may be implemented using a planar conductor (e.g., a conductive sheet or conductive coating). In one embodiment, the sheet radiator may include a conductive sheet, such as a copper sheet. In one embodiment, the sheet radiator may include a conductive coating, such as silver paste. The shape of the sheet radiator includes circular, rectangular, and annular shapes, and this application does not limit the specific shape. The structure of a microstrip antenna generally consists of a dielectric substrate, a radiator, and a ground plane, wherein the dielectric substrate is disposed between the radiator and the ground plane.

[0108] Radiators may also include slots or gaps formed on a conductor, for example, closed or semi-closed slots or gaps formed on a grounded conductor surface. In one embodiment, a slotted or slit radiator may be simply referred to as a slot antenna or a gap antenna. In one embodiment, the radial dimension (e.g., including width) of the slot or gap of the slot antenna / gap antenna is much smaller than the wavelength (e.g., the dielectric wavelength) (e.g., less than 1 / 16 of the wavelength), while the length dimension may be comparable to the wavelength (e.g., the dielectric wavelength) (e.g., a length of approximately 1 / 8 of the wavelength, or 1 / 8 to 1 / 4, or 1 / 4 to 1 / 2, or longer). In one embodiment, a radiator with a closed slot or gap may be simply referred to as a closed slot antenna. In one embodiment, a radiator with a semi-closed slot or gap (e.g., an opening added to a closed slot or gap) may be simply referred to as an open slot antenna. In some embodiments, the gap shape is elongated. In some embodiments, the length of the gap is approximately half a wavelength (e.g., the dielectric wavelength). In some embodiments, the length of the gap is approximately an integer multiple of a wavelength (e.g., one dielectric wavelength). In some embodiments, the slot can be fed by transmission lines connected across one or both sides, thereby exciting a radio frequency electromagnetic field on the slot and radiating electromagnetic waves into space. In one embodiment, the radiator of the slot antenna or gap antenna can be implemented by a conductive frame grounded at both ends, also known as a frame antenna; in this embodiment, the slot antenna or gap antenna can be viewed as including a linear radiator, the linear radiator being spaced apart from the ground and grounded at both ends, thereby forming a closed or semi-closed slot or gap. In one embodiment, the radiator of the slot antenna or gap antenna can be implemented by a support conductor grounded at both ends, also known as a support antenna.

[0109] Ground (GND): Generally refers to at least a portion of any grounding layer, ground plane, or grounding metal layer within an electronic device (such as a mobile phone), or at least a portion of any combination of the aforementioned grounding layers, ground planes, or grounding components. "Ground" can be used for grounding components within an electronic device. In one embodiment, "ground" can be the grounding layer of a circuit board in an electronic device, or a grounding metal layer formed by a ground plane formed within the frame of the electronic device or a metal film formed beneath the screen. In one embodiment, the circuit board can be a printed circuit board (PCB), such as an 8-layer, 10-layer, or 12-14-layer board having 8, 10, 12, 13, or 14 layers of conductive material, or components separated and electrically insulated by dielectric or insulating layers such as fiberglass or polymers. In one embodiment, the circuit board includes a dielectric substrate, a grounding layer, and a trace layer, with the trace layer and grounding layer electrically connected via vias. In one embodiment, components such as displays, touchscreens, input buttons, transmitters, processors, memory, batteries, charging circuits, and system-on-chip (SoC) architectures can be mounted on or connected to a circuit board; or electrically connected to trace layers and / or ground layers in the circuit board. For example, an RF source is disposed on a trace layer.

[0110] Any of the aforementioned grounding layers, ground planes, or grounding metal layers are made of conductive materials. In one embodiment, the conductive material may be any of the following: copper, aluminum, stainless steel, brass and their alloys, copper foil on an insulating substrate, aluminum foil on an insulating substrate, gold foil on an insulating substrate, silver-plated copper, silver-plated copper foil on an insulating substrate, silver foil on an insulating substrate and tin-plated copper, graphite-impregnated cloth, graphite-coated substrates, copper-plated substrates, brass-plated substrates, and aluminum-plated substrates. Those skilled in the art will understand that grounding layers / ground planes / grounding metal layers may also be made of other conductive materials.

[0111] A power supply circuit is a combination of all circuits used for receiving and transmitting radio frequency (RF) signals. It can include a transceiver and an RF front-end. In some cases, the term "power supply circuit" is narrowly interpreted as an RF integrated circuit (RFIC), which can be considered to include both the RF front-end chip and the transceiver. The power supply circuit has the function of converting radio waves (e.g., RF signals) into electrical signals (e.g., digital signals). It is generally considered part of the RF component.

[0112] 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. Typically, the matching circuit is a combination of circuits coupled between the radiator and the ground plane. In one embodiment, the matching circuit may include a tuning circuit and / or electronic components, which may be electronic components for switching the coupling connection of the radiator. The matching circuit has the function of impedance matching and / or frequency tuning. It is generally considered to be part of the antenna.

[0113] Open terminal, closed terminal: In some embodiments, open terminal and closed terminal are, for example, relative to whether or not they are grounded; the closed terminal is grounded, and the open terminal is not grounded. In some embodiments, open terminal and closed terminal are, for example, relative to other conductors; the closed terminal is electrically connected to other conductors, and the open terminal is not electrically connected to other conductors. In one embodiment, the open terminal may also be referred to as a floating terminal, free terminal, open terminal, or open-circuit terminal. In one embodiment, the closed terminal may also be referred to as a ground terminal or short-circuit terminal. It should be understood that in some embodiments, other conductors can be coupled through the open terminal to transfer coupled energy (which can be understood as transferring current).

[0114] Electrical length: can be the ratio of physical length (i.e., mechanical length or geometric length) to the wavelength of the transmitted electromagnetic wave. Electrical length can satisfy the following formula:

[0115] in, Let L be the electrical length, L be the physical length, and λ be the wavelength of the electromagnetic wave.

[0116] Wavelength: or operating wavelength, can be the wavelength corresponding to the center frequency of the resonant frequency or the center frequency of the operating frequency band supported by the antenna. For example, assuming the center frequency of the B1 uplink band (resonant frequency from 1920MHz to 1980MHz) is 1955MHz, then the operating wavelength can be the wavelength calculated using this frequency. Not limited to the center frequency, "operating wavelength" can also refer to the wavelength corresponding to the non-center frequency of the resonant frequency or operating frequency band.

[0117] Coupling can be understood as direct coupling and / or indirect coupling. "Coupled connection" can be understood as a direct coupling connection and / or indirect coupling connection. Direct coupling, also known as "electrical connection," refers to components being in direct or indirect physical contact and electrically conductive. For example, in circuit construction, different components are connected through physical lines that can transmit electrical signals, such as copper foil or wires on a printed circuit board (PCB). "Indirect coupling" can be understood as two conductors conducting electricity through a gap or without contact. In one embodiment, indirect coupling can also be called capacitive coupling, for example, using the coupling between two conductive parts to form an equivalent capacitance to achieve signal transmission.

[0118] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0119] As mentioned earlier, conventional walkie-talkies all use large-sized external antennas, which result in good antenna performance in the 400-410MHz frequency band. For example, conventional walkie-talkie 1 uses a spiral antenna 101 as shown in Figure 1(a), or a whip antenna 102 as shown in Figure 1(b).

[0120] It is understood that the size of the external helical antenna 101 or whip antenna 102 is not limited by space. Therefore, the corresponding antenna length can be set according to the antenna performance at different lengths. For example, the physical length of the helical antenna 101 or whip antenna 102 used in the aforementioned 400-410MHz frequency band may be more than one hundred millimeters.

[0121] However, traditional walkie-talkies lack portability, so walkie-talkie functionality can be integrated into electronic devices (such as mobile phones and watches). These devices can directly reuse existing antennas, such as low-frequency antennas (e.g., antennas operating in the 699–960 MHz band), to achieve walkie-talkie functionality. This direct reuse of existing antennas, without the need for additional antennas, saves space in the electronic device.

[0122] It should be noted that the electronic devices in this application embodiment include, but are not limited to, mobile stations (MS) and mobile terminals (MT). For example, the electronic device can be a mobile phone, wearable device (e.g., a watch), smart TV, electronic device, tablet computer, desktop computer, laptop computer, virtual reality (VR) device, augmented reality (AR) device, terminal in industrial control, terminal in self-driving, terminal in remote medical surgery, terminal in smart grid, terminal in transportation safety, terminal in smart city, terminal in smart home, and other devices containing antennas. This application embodiment does not limit the specific form of the electronic device. For ease of description, a mobile phone is used as an example below.

[0123] Figures 2A and 2B show front views of the mobile phone 2 in some embodiments. It should be noted that in the figures of this application, the X-axis direction can be the width direction of the mobile phone 2; for example, the positive X-axis direction can be from the left side to the right side of the mobile phone 2. The Y-axis direction can be the length direction of the mobile phone 2; for example, the positive Y-axis direction can be from the bottom end to the top end of the mobile phone 2. In some embodiments, the dimension of the mobile phone 2 along its length direction can be greater than its dimension along its width direction; or, in other embodiments, the dimension of the mobile phone 2 along its length direction can be less than or equal to its dimension along its width direction. The Z-axis direction can be the thickness direction of the mobile phone 2; for example, the positive Z-axis direction can be from the back end to the front end of the mobile phone 2. The front and back ends are the two side surfaces of the mobile phone 2 arranged opposite each other along the Z-axis direction, where the front end can represent the surface facing the user when the user holds the mobile phone 2, and the back end can represent the surface facing away from the user when the user holds the mobile phone 2. The X-axis, Y-axis, and Z-axis directions can be mutually perpendicular.

[0124] As shown in Figures 2A and 2B, the mobile phone 2 includes a casing 10 and a display screen 20. The casing 10 surrounds the display screen 20, forming the frame and back cover of the mobile phone 2. The back cover and the display screen 20 are located on opposite sides along the Z-axis, with the display screen 20 located on the front of the mobile phone 2 and the back cover located on the back of the mobile phone 2.

[0125] The mobile phone 2 also includes an antenna 30. In some embodiments, the housing 10 is made of metal, and at least a portion of the housing 10 (e.g., the left side border shown in the dashed box in Figure 2A, or the corner portion shown in the dashed box in Figure 2B) is used to form the antenna 30; in other words, the housing 10 and the antenna 30 are integrally connected. Alternatively, in other embodiments, the housing 10 is made of plastic, and the antenna 30 is disposed within the cavity formed by the housing 10 and the display screen 20. To ensure the external radiation performance of the antenna 30, the antenna 30 is disposed against the edge of the housing 10, such as the left side border shown in the dashed box in Figure 2A, or the corner portion shown in the dashed box in Figure 2B, or it may also be disposed at the top or bottom of the mobile phone 2.

[0126] As mentioned earlier, electronic devices can directly reuse existing antennas to realize walkie-talkie functions. For example, mobile phone 2 can realize walkie-talkie functions based on antenna 30.

[0127] For example, Figure 2C shows a schematic diagram of the internal structure of a mobile phone 2. As shown in Figure 2C, the mobile phone 2 includes a first radio frequency (RF) chip 201 and a second RF chip 202, wherein the first RF chip 201 and the second RF chip 202 can be used to process RF signals of different frequency bands or different communication modes, respectively. For example, the first RF chip 201 is used to process RF signals in the 699–960 MHz frequency band under mobile communication mode, and the second RF chip 202 is used to process RF signals in the 400–410 MHz frequency band under walkie-talkie communication mode.

[0128] In some embodiments, as shown in FIG2C, the first RF chip 201 and the second RF chip 202 are respectively connected to the antenna 30 via a switch 203, and the first RF chip 201 and the second RF chip 202 are connected to the same feed point of the antenna 30. The switch 203 can be used to control the feed point of the antenna 30 to be connected to the first RF chip 201 or to the second RF chip 202 according to the current communication mode, so that the antenna 30 is used to transmit and receive RF signals in the current communication mode. For example, in walkie-talkie mode, the mobile phone 2 controls the switch 203 to switch to the second RF chip 202, so that the second RF chip 202 is connected to the feed point of the antenna 30; in mobile communication mode, the mobile phone 2 controls the switch 203 to switch to the first RF chip 201, so that the first RF chip 201 is connected to the feed point of the antenna 30.

[0129] It is understood that the switching control of switch 203 can be executed by the first radio frequency chip 201 / the second radio frequency chip 202, or by other electronic devices (such as processors) in the mobile phone 2.

[0130] Alternatively, in some embodiments, as shown in FIG2D, FIG2D illustrates another schematic diagram of the internal structure of a mobile phone 2. The difference from FIG2C is that the first RF chip 201 and the second RF chip 202 are respectively connected to different feed points on the antenna 30. The first RF chip 201 and the second RF chip 202 can adaptively process the RF signal according to the current communication mode, or other electronic devices in the mobile phone 2 (e.g., a processor) can select either the first RF chip 201 or the second RF chip 202 to process the RF signal according to the current communication mode.

[0131] It is understood that the first RF chip 201 and the second RF chip 202 described above can be integrated and packaged together as a single integrated chip, or they can be packaged in a distributed manner, meaning that the first RF chip 201 and the second RF chip 202 are two independent chips. It should be noted that this application does not limit the specific form of the RF chip or the antenna architecture; the above embodiments are merely examples.

[0132] However, the size of the antenna 30 in the current mobile phone 2 is much smaller than that of the antenna in the traditional walkie-talkie 1 (over 100 millimeters). For example, the size of the antenna 30 operating in the 699–960 MHz frequency band is generally 4–11 centimeters. It performs well in the 699–960 MHz band but poorly in the 400–410 MHz band. Therefore, when implementing walkie-talkie functionality based on existing antennas in electronic devices, the low performance of these antennas in the corresponding frequency bands results in poor walkie-talkie performance.

[0133] Therefore, in order to improve the antenna performance of electronic devices when implementing walkie-talkie functions based on existing antennas, this application provides an interface display method for electronic devices. Taking mobile phone 2 as an example, when mobile phone 2 enters walkie-talkie mode (antenna 30 operates at 400-410MHz), a guidance interface is displayed on the screen 20 to guide the user's grip on mobile phone 2, so that the user contacts the location of antenna 30 on the outer casing 10, such as the antenna 30 on the left side frame as shown in Figure 2A, or the antenna 30 at the corner as shown in Figure 2B. It is understood that human contact or proximity to the antenna can increase the antenna aperture (the effective size for receiving or transmitting electromagnetic waves), but it will also cause losses in antenna radiation. However, based on the actual shape of antenna 30, it can be determined that when the human body contacts or is close to a specific part of antenna 30 (e.g., the point of maximum current on the radiator), the benefit of increasing the antenna aperture can outweigh the loss of radiation caused by the human body. The combined effect can improve antenna performance. Therefore, this application uses a guidance interface to guide the user to contact the location of antenna 30, thereby improving the performance of antenna 30 in walkie-talkie mode and improving the reuse rate of antenna 30.

[0134] It should be noted that this application does not limit the form, location, or number of antennas used in the electronic device in walkie-talkie mode. For example, when multiplexing two or more antennas, the user can be guided to simultaneously contact the location of each antenna on the casing 10. For ease of explanation, the following uses the multiplexing of a single antenna 30 as an example. Furthermore, this application does not limit the specific form of the antennas used in walkie-talkie mode; the specific form and location of the antennas in each embodiment are merely examples. For example, the antenna can be a slotted antenna, an IFA antenna, a monopole antenna, or any other arbitrary form. The antenna can be located on the left side, right side, top, bottom, or corner of the mobile phone 2. This application can reuse any antenna in the electronic device for walkie-talkie mode. In addition, this application does not limit the original operating frequency used for the multiplexed antennas, nor does it limit whether the two or more antennas operate at the same frequency when multiplexing two or more antennas.

[0135] The technical solutions of this application will be further described below based on different structures of the antenna 30. Figure 3 shows the specific structure of the antenna 30 in some embodiments.

[0136] In some embodiments, as shown in FIG3, the antenna 30 may be a slotted antenna. The antenna 30 includes a radiator 301 extending along the Y-axis direction. There is a gap between the radiator 301 and the ground plane 302. One end of the radiator 301 includes a ground point D1, and the other end includes a feed point P1. The feed point P1 is coupled to the radiator 301 and is used to feed in radio frequency signals (e.g., radio frequency signals in the operating frequency band of walkie-talkie communication). The radiator 301 is connected to the ground plane 302 through the ground point D1 and connected to a feed circuit through the feed point P1. The feed circuit is used to receive and transmit radio frequency signals.

[0137] In some embodiments, antenna 30 operates in the 699–960 MHz frequency band. Therefore, a first matching circuit is also included between the feed point P1 and the feed circuit, and the feed point P1 and the first matching circuit are used for frequency tuning in the 699–960 MHz frequency band.

[0138] In some embodiments, the mobile phone 2 reuses antenna 30 to implement walkie-talkie mode. Therefore, the power supply circuit can be used to receive and transmit radio frequency signals at the frequency corresponding to walkie-talkie mode. Alternatively, the mobile phone 2 may integrate a walkie-talkie function module 40 (including a radio frequency front-end chip and a transceiver). The radiator 301 is electrically connected to the walkie-talkie function module 40 through the power supply point P1. The walkie-talkie function module 40 is specifically used to receive and transmit radio frequency signals in walkie-talkie mode.

[0139] Correspondingly, a second matching circuit is also included between the power supply point P1 and the power supply circuit / walkie-talkie function module 40. The power supply point P1 and the second matching circuit are used for frequency tuning of the corresponding frequency band of the walkie-talkie mode.

[0140] It is understandable that when the antenna 30 is fed, the current and electric field distribution on the radiator 301 are as follows: the electric field gradually increases from the grounding point D1 to the feeding point P1, and the electric field is strongest at the feeding point P1; the current gradually increases from the feeding point P1 to the grounding point D1, and the current is the largest at the grounding point D1.

[0141] It is understandable that the human body is conductive. If a person comes into contact with the point of maximum current on the radiator 301, such as grounding point D1, the person acts as an extension branch of the antenna, increasing the antenna aperture. Furthermore, the electric field at grounding point D1 is weak, resulting in minimal loss of radiation performance due to the person, thus improving antenna performance. Therefore, when implementing a walkie-talkie function based on antenna 30, the performance of antenna 30 in the 400–410MHz frequency band can be improved by having a person come into contact with the grounding point D1 of antenna 30, thereby enhancing the walkie-talkie communication effect.

[0142] In some embodiments, as shown in Figure 2A, the grounding point D1 of the antenna 30 is located approximately on the left side of the phone 2 near the bottom. The feed point P1 is located approximately on the left side of the phone 2, slightly towards the top. That is, the grounding point D1 is closer to the bottom of the phone 2 than the top. This ensures that the user can contact the grounding point D1, making the grip more comfortable for the user and reducing the burden of holding the phone in walkie-talkie mode.

[0143] Based on this, in some embodiments, the mobile phone 2 can guide the user to contact the grounding point D1 of the antenna 30 through the guide interface 400 shown in FIG4A.

[0144] As shown in Figure 4A, when the mobile phone 2 enters walkie-talkie mode, it can display interface 400, which includes guidance information 410. For example, the guidance information 410 may include guidance text "Please place your finger here" 410a, guidance contact area 410b, and pointing arrow 410c.

[0145] The guiding contact area 410b can be defined based on the location of the point of maximum current in the antenna 30, i.e., the grounding point D1. For example, the dimension of the guiding contact area 410b in the Y-axis direction can be 10-20 mm extending from the grounding point D1 in both the positive and negative directions. It can be understood that the user does not need to precisely contact the grounding point D1; the current in the antenna 30 is relatively high within the guiding contact area 410b, and human contact with this guiding contact area 410b can expand the radiation range of the antenna 30 and improve its performance.

[0146] It should be noted that this application does not limit the specific content of the guidance information 410; anything used to guide the user to contact the antenna 30 is within the scope of protection of this application.

[0147] Furthermore, the contact with antenna 30 mentioned in this application includes both direct and indirect contact. For example, when antenna 30 is a metal-framed antenna, the radiator 301 is formed as part of the outer casing 10, so when the user touches the outer casing 10, they are in direct contact with antenna 30. As another example, when antenna 30 is located inside mobile phone 2, the user can indirectly contact antenna 30 by touching the outer casing 10.

[0148] Furthermore, the preset area of ​​the housing 10 mentioned in this application can be the area of ​​the housing 10 that the user contacts based on the guide contact area in the guide interface. For example, in Figure 4A, the user contacts the preset area 10A on the housing 10 based on the guide contact area 410b. That is, the preset area in this application can refer to the guide contact area in the display interface; therefore, the relevant description of the guide contact area applies to the preset area. For example, as shown in Figure 4A, the preset area is aligned with the guide contact area in the X-axis direction. This can be understood as the preset area having the same position and size along the Y-axis direction as the guide contact area. Since the guide contact area is defined based on the point of maximum current on the radiator, the preset area can be understood as being aligned with the point of maximum current.

[0149] Figure 4B shows a schematic diagram of the interface 400 in some other embodiments. As shown in Figure 4B, the guidance information 410 may include, in addition to the guidance text "Please place your finger here" 410a, the guidance contact area 410b, and the pointing arrow 410c, a guidance contact area 410d and a pointing arrow 410e. The guidance contact areas 410d and 410b are located on opposite sides of the interface 400 along the X-axis, thus guiding the user to hold the phone 2 on both sides, resulting in a more stable grip.

[0150] Alternatively, as mentioned above, mobile phone 2 can reuse two or more antennas to achieve walkie-talkie functionality. Therefore, the aforementioned guiding contact area 410d can also be a region defined based on the location of the maximum current point of the other antennas besides antenna 30. It is understood that the location of the guiding contact area 410d in this embodiment is defined based on the actual location of the reused antennas in mobile phone 2. For example, the guiding contact area 410d can also be located at the bottom of mobile phone 2, and this application does not limit this.

[0151] In this embodiment, different postures of a user holding the mobile phone 2 were simulated based on a hand model, and the performance of the antenna 30 under different grip postures was simulated and tested.

[0152] For example, Figure 5A shows a schematic diagram of a typical posture for a user to hold a mobile phone 2. Typically, a user holds the mobile phone 2 in the posture shown in Figure 5A. At this time, the fingers will come into contact with the feed point P1 of the antenna 30. Since the electric field at the feed point P1 is relatively large, more of the radiated energy of the antenna 30 is absorbed by the human body, resulting in a decrease in the performance of the antenna 30.

[0153] Figure 5B shows a schematic diagram of a user's grip on the mobile phone 2 based on guidance information 410. Figures 5B(a) and (b) show schematic diagrams of grip postures at different angles.

[0154] As shown in Figure 5B, the guidance information 410 displayed on the interface 400 of the mobile phone 2 guides the user to adopt a new grip posture, which can prevent the user from touching the feed point P1, thereby avoiding the electric field from entering the human body and reducing the loss of radiated energy of the antenna 30 by the human body; at the same time, it can guide the user to touch the grounding point D1. Since the current at the grounding point D1 is relatively large (the maximum current in the 400-410MHz frequency band will not exceed the current range that the human body can withstand), human body contact can greatly increase the antenna aperture, thereby making the antenna 30 perform better in walkie-talkie mode.

[0155] Figure 6 shows schematic diagrams of the performance curves of the antenna 30 under different grip postures in some embodiments. The horizontal axis represents the operating frequency of the antenna 30, and the vertical axis represents the radiation efficiency of the antenna 30. Curve 1 is the performance curve of the antenna 30 measured based on the conventional grip posture shown in Figure 5A; curve 2 is the performance curve of the antenna 30 measured based on the new grip posture shown in Figure 5B; and curve 3 is the performance curve of the antenna 30 measured in free space, i.e., when the phone 2 is not held.

[0156] As shown in Figure 6, when the mobile phone 2 is in walkie-talkie mode, for example, when the antenna 30 is operating in the 400MHz frequency band, the radiation efficiency of the new grip shown in Figure 5B is approximately -8.6dB, the radiation efficiency of the conventional grip is approximately -14.2dB, and the radiation efficiency in free space is approximately -9.9dB. It can be seen that the radiation efficiency of the antenna 30 in the new grip is 5dB+ higher than that in the conventional grip, and 1dB+ higher than that in free space. That is, the new grip significantly improves the radiation efficiency of the antenna 30.

[0157] Figure 7 shows a schematic diagram of the structure of antenna 30 in some other embodiments.

[0158] In some embodiments, as shown in FIG7, the antenna 30 may be a wire antenna. The antenna 30 includes a radiator 301 extending along the Y-axis direction. There is a gap between the radiator 301 and the ground 302. One end of the radiator 301 includes a feed point P2. The difference from the above embodiments is that in this embodiment, the other end of the radiator 301 is not grounded. The ungrounded other end is referred to as the open end below.

[0159] For antenna 30 shown in Figure 7, the current is maximum at feed point P2 when it is fed. Referring to Figure 2A, the feed point P2 of antenna 30 is located approximately on the left side of mobile phone 2 near the bottom.

[0160] Since the location of the maximum current point (feed point P2) of antenna 30 in this embodiment is similar to that of the maximum current point (ground point D1) of antenna 30 shown in Figure 3 within the mobile phone 2, in this embodiment, the mobile phone 2 can guide the user's grip posture through the interface 400 shown in Figure 4A or Figure 4B, so that the user contacts the feed point P2 of antenna 30. It can be understood that in this embodiment, the guided contact area 410b in the interface 400 is a region defined based on the location of the feed point P2 of antenna 30.

[0161] For example, Figure 8 shows another schematic diagram of a user holding the mobile phone 2 based on the guide interface 400.

[0162] As shown in Figure 8, the user is guided to adopt a new grip posture through the guidance information 410 in the interface 400 of the mobile phone 2, so that the user touches the feed point P2. Since the current of the feed point P2 is large and the electric field is small, human contact can greatly increase the antenna aperture, thereby making the antenna 30 perform better in walkie-talkie mode.

[0163] Similarly, the performance of the antenna 30 in the grip posture shown in Figure 8 was simulated and tested in this embodiment of the application.

[0164] Figure 9 shows schematic diagrams of the performance curves of antenna 30 under different grip postures in other embodiments. The horizontal axis represents the operating frequency of antenna 30, and the vertical axis represents the radiation efficiency of antenna 30. Curve 1 is the performance curve of antenna 30 measured based on the new grip posture shown in Figure 8, and curve 2 is the performance curve of antenna 30 measured in free space, i.e., when mobile phone 2 is not held.

[0165] As shown in Figure 9, when the mobile phone 2 is in walkie-talkie mode, for example, when the antenna 30 is operating in the 400MHz frequency band, its radiation efficiency in free space is approximately -11.5dB, while the radiation efficiency with the new grip posture shown in Figure 8 is approximately -10.1dB. It can be seen that the radiation efficiency of the antenna 30 with the new grip posture is 1dB+ higher than that in free space; that is, the new grip posture significantly improves the radiation efficiency of the antenna 30.

[0166] Figure 10A shows the current distribution on the radiator 301 and the ground plane 302 in the antenna 30 shown in Figure 7.

[0167] As shown in Figure 10A, the current loop flows from the open end of the radiator 301 to the feed point P2 at the other end, through the feed point P2 to the ground 302, and then to the area of ​​the ground 302 that is far away from the feed point P2 (the area within the dashed box in Figure 10A, referred to below as the end of the ground 302). That is, the end of the ground 302 is farther away from the feed point P2 than the other end of the ground 302 along the Y-axis.

[0168] It is understandable that while human contact with the open end of radiator 301 can increase the antenna aperture, the large electric field at the open end causes the losses from human contact to outweigh the gains from the increased aperture, resulting in a deterioration in antenna performance. However, as shown in Figure 10A, the current is weaker at the end of ground plane 302. Human contact with the end of ground plane 302 can increase the aperture while maintaining low energy absorption losses, resulting in an improved antenna performance.

[0169] Based on this, in some embodiments, the mobile phone 2 may add guidance information in the guidance interface 400 to instruct the user to hold the floor 302 at that position, according to the position of the end of the floor 302 in the mobile phone 2.

[0170] In some embodiments, the end of the floor 302 is located at the top of the mobile phone 2. Referring to FIG10B, the mobile phone 2 has a short side 210 and a short side 220 disposed opposite to each other along the Y-axis direction. The top of the mobile phone 2 may include a short side portion 210a near the short side 210, and the end of the floor 302 may refer to the short side portion 210a.

[0171] The short side portion 210a can also be understood as the region extending from the short side 210 towards the short side 220. The ratio between the dimension y1 of this region along the Y-axis and the dimension y2 of the mobile phone 2 along the Y-axis can be 1 / 10 to 1 / 4. For example, y1 / y2 can be equal to 1 / 10, 1 / 8, 1 / 5, or 1 / 4. Specifically, the dimension of y1 can be in the range of 1 cm to 5 cm, for example, 1 cm, 2 cm, 3 cm, or 5 cm.

[0172] For example, if the end of the floor 302 is near the top of the mobile phone 2, the guide interface displayed on the mobile phone 2 may include guide information pointing to the top of the mobile phone 2. Figure 11A shows a schematic diagram of a user holding the mobile phone 2 based on the guide interface 400. Figures 11A(a) and (b) show schematic diagrams of the holding posture at different angles.

[0173] As shown in Figure 11A, the guidance information 410 in the interface 400 of the mobile phone 2 guides the user to adopt a new grip posture, which can guide the user to touch or get close to the end of the floor 302, while avoiding the user touching the feed point P2. This increases the antenna aperture while keeping the energy absorption loss low, which helps to improve the antenna performance.

[0174] It should be noted that the guidance information on the guidance interface 400 varies depending on the position of the end of the floor 302 within the phone 2, resulting in different user grip postures. Figure 11B illustrates another user grip posture for the phone 2. As shown in Figure 11B, the user can hold the phone 2 with both hands, ensuring contact with or close proximity to the end of the floor 302 while improving the stability of the grip. It is understood that this application does not limit the specific content of the guidance interface 400 or the user grip posture.

[0175] In this embodiment, the performance of the antenna 30 was simulated and tested when the user held the top of the mobile phone 2.

[0176] Figure 12 shows schematic diagrams of the performance curves of the antenna 30 under different grip postures in other embodiments. The horizontal axis represents the operating frequency of the antenna 30, and the vertical axis represents the radiation efficiency of the antenna 30. Curve 1 is the performance curve of the antenna 30 measured in a new grip posture where the user holds the top of the phone 2, and curve 2 is the performance curve of the antenna 30 measured in free space, i.e., when the phone 2 is not held.

[0177] As shown in Figure 12, when the mobile phone 2 is in walkie-talkie mode, for example, when the antenna 30 is operating in the 400MHz frequency band, its radiation efficiency in free space is approximately -12.4dB, while the radiation efficiency with the new grip is approximately -5.1dB. It can be seen that the radiation efficiency of the antenna 30 with the new grip is 7dB+ higher than that in free space; that is, the new grip significantly improves the radiation efficiency of the antenna 30.

[0178] Figure 13A shows a schematic diagram of the structure of the antenna 30 in some other embodiments.

[0179] In some embodiments, as shown in FIG13A, the radiator 301 of the antenna 30 is "L"-shaped. There is a gap between the radiator 301 and the floor 302. Referring to FIG2B, the radiator 301 is located at the corner of the mobile phone 2, such as the upper left corner, the upper right corner, the lower left corner, or the lower right corner, which is not limited in this application.

[0180] Taking the radiator 301 located at the upper left corner of the mobile phone 2 as an example, specifically, the radiator 301 includes a first side 301-1 extending along the X-axis and a second side 301-2 extending along the Y-axis. One end of the first side 301-1 extending along the X-axis is connected to one end of the second side 301-2 extending along the Y-axis, and the connection portion of the first side 301-1 and the second side 301-2 forms the corner region of the radiator 301 (as shown in the circular dashed box M). In some embodiments, as shown in FIG13A, the other end of the first side 301-1 extending along the X-axis is an open end, and the other end of the second side 301-2 extending along the Y-axis includes a feed point P3.

[0181] In this embodiment, the end of the floor 302 is shown in the rectangular dashed box in Figure 13A, and the current is relatively weak within the rectangular dashed box.

[0182] In this embodiment, the end of the floor 302 is located at the bottom of the mobile phone 2. Referring to FIG13B, the bottom of the mobile phone 2 may include a short side portion 220a near the short side 220, and the end of the floor 302 may refer to the short side portion 220a.

[0183] The short side portion 220a can also be understood as the region extending from the short side 220 towards the short side 210. The ratio between the dimension y3 of this region along the Y-axis and the dimension y2 of the mobile phone 2 along the Y-axis can be 1 / 10 to 1 / 4. For example, y3 / y2 can be equal to 1 / 10, 1 / 8, 1 / 5, or 1 / 4. Specifically, the dimension of y3 can range from 1 cm to 5 cm, for example, 1 cm, 2 cm, 3 cm, or 5 cm.

[0184] The embodiments of this application simulated and tested the performance of the antenna 30 under different conditions, such as when a human body is in contact with the open end, corner area and end of the floor 302 of the radiator 301 respectively, and when both hands are in contact with the corner area of ​​the radiator 301 and the end of the floor 302 at the same time.

[0185] Figure 14 shows schematic diagrams of the performance curves of the antenna 30 under different grip postures in other embodiments. The horizontal axis represents the operating frequency of the antenna 30, and the vertical axis represents the radiation efficiency of the antenna 30. Curve 1 is the performance curve of the antenna 30 measured when the user simultaneously contacts the corner area of ​​the radiator 301 and the end of the floor 302; curve 2 is the performance curve of the antenna 30 measured when the user contacts the end of the floor 302; curve 3 is the performance curve of the antenna 30 measured when the user contacts the corner area of ​​the radiator 301; curve 4 is the performance curve of the antenna 30 measured when the user contacts the open end of the radiator 301; and curve 5 is the performance curve of the antenna 30 measured in free space, i.e., when the phone 2 is not held.

[0186] As shown in Figure 14, when the mobile phone 2 is in walkie-talkie mode, for example, when the antenna 30 is operating in the 400MHz frequency band, the radiation efficiency in free space is approximately -8.2dB, the radiation efficiency of the antenna 30 is approximately -7.2dB when it is in contact with the open end of the radiator 301, the radiation efficiency of the antenna 30 is approximately -6.8dB when it is in contact with the corner area of ​​the radiator 301, the radiation efficiency of the antenna 30 is approximately -3.8dB when it is in contact with the end of the floor 302, and the radiation efficiency of the antenna 30 is approximately -3.3dB when it is in contact with both the end of the floor 302 and the corner area of ​​the radiator 301.

[0187] It can be seen that contacting the open end, corner area, and end of the floor 302 of the radiator 301 separately, or contacting both the corner area of ​​the radiator 301 and the end of the floor 302 simultaneously with both hands, significantly improves antenna performance. Furthermore, contacting both the corner area of ​​the radiator 301 and the end of the floor 302 simultaneously with both hands results in a greater performance improvement than contacting only the open end, corner area, or end of the floor 302.

[0188] In other embodiments, the radiator 301 may have a form different from that shown in FIG13A. FIG15A to FIG15E illustrate the form of the radiator 301 in other embodiments.

[0189] As shown in Figure 15A, the difference from Figure 13A is that the other end of the first side 301-1 extending along the X-axis includes the power supply point P3, and the other end of the second side 301-2 extending along the Y-axis is an open end.

[0190] As shown in Figure 15B, the difference from Figure 13A is that the other end of the first side 301-1 extending along the X-axis includes a feed point P3, and the radiator 301 also includes a grounding point D2, which is located at the other end of the second side 301-2 extending along the Y-axis.

[0191] As shown in Figure 15C, the difference from Figure 13A is that the radiator 301 also includes a grounding point D2, which is located at the other end of the first side 301-1 extending along the X-axis.

[0192] As shown in Figure 15D, the difference from Figure 13A is that the other end of the second side 301-2 extending along the Y-axis is an open end, and the radiator 301 also includes a grounding point D2. The feed point P3 and the grounding point D2 are both located at the other end of the first side 301-1 extending along the X-axis.

[0193] As shown in Figure 15E, the difference from Figure 13A is that the radiator 301 also includes a grounding point D2. The feed point P3 and the grounding point D2 are both located at the other end of the second side 301-2 extending along the Y-axis.

[0194] It is understandable that, through testing and simulation, for the different forms of radiators 301 shown in Figures 15A to 15E, human contact with the open end, corner area, or end of the floor 302 of the radiator 301, or simultaneous contact with the corner area of ​​the radiator 301 and the end of the floor 302, can all lead to improved antenna performance.

[0195] It is understood that in this embodiment, the mobile phone 2 may display a guidance interface similar to that shown in Figure 4A or Figure 4B to guide the user to contact specific parts of the antenna 30 (such as the open end, corner, and end of the floor 302 of the radiator 301). The specific guidance interface can be designed according to actual conditions, and this application does not limit the specific content of the interface (e.g., static screen, dynamic screen, text / image / symbol display elements in the screen).

[0196] The following example uses a watch as an electronic device. Figure 16A shows a front view of watch 3 in some embodiments.

[0197] As shown in Figure 16A, the watch 3 includes a watch body 50 and a watch strap 60. The watch body 50 and the watch strap 60 can be fixedly connected or detachably connected. The watch body 50 can be circular, rectangular, square, oval, or other shapes. For example, Figure 16B shows an example where the watch body 50 is rectangular in some embodiments. As shown in Figure 16A or Figure 16B, the watch body 50 can include a housing 51 and a display screen 52. The housing 51 includes an annular frame 510, which can be a circular annular frame as shown in Figure 16A, or a rectangular annular frame or other annular frame shapes as shown in Figure 16B. The housing 51 and the display screen 52 enclose a receiving space, which can be used to accommodate various functional modules and electronic components of the watch 2, including but not limited to processors, memory, batteries, antennas, etc.

[0198] The watch 3 also includes an antenna 70. The watch 3 can implement a two-way communication function based on the antenna 70. In some embodiments, the annular frame 510 of the housing 51 is made of metal, and at least a portion of the annular frame 510 is used to form the antenna 70, for example, the portion shown in the dashed box in Figure 16A or Figure 16B (i.e., the first part of this application) is the antenna 70, or the entire annular frame 510 of the housing 51 is the antenna 70. In other embodiments, the housing 51 is made of plastic, and the antenna 70 is disposed within the accommodating space formed by the housing 51 and the display screen 52. For example, the antenna 70 is disposed against the annular frame 510 of the housing 51, for example, at the position of the annular frame shown in the dashed box in Figure 16A or Figure 16B, or surrounds and adheres to the entire annular frame 510 of the housing 51.

[0199] It should be noted that this application does not limit the specific form of antenna 70. Different forms of antenna 70 are illustrated below with reference to Figures 17A and 17B.

[0200] Figure 17A shows a schematic diagram of the antenna 70 in some embodiments. The antenna 70 includes a radiator 701, which is arc-shaped and extends circumferentially along the floor 702, and is radially spaced from the floor 702. The radiator 701 includes a feed point P4, which is coupled to the radiator 701 and used to feed in radio frequency signals in the operating frequency band of walkie-talkie communication. Exemplarily, the feed point P4 may be located at one end of the circumferentially extending radiator 701.

[0201] It is understood that, in this embodiment, referring to FIG16A, the radiator 701 may be a part of the annular frame 510 of the housing 51 (e.g., shown by the dashed box). Continuing to refer to FIG17A, the annular frame 510 includes a first slit 510A and a second slit 510B, and the radiator 701 may be a first portion 5101 of the annular frame 510 between the first slit 510A and the second slit 510B.

[0202] Figure 17B shows a schematic diagram of the radiator 701 in some other embodiments. The difference from Figure 17A is that the location of the feed point P4 is different. In this embodiment, the radiator 701 can be a second part 5102 of the annular frame 510 between the first slit 510A and the second slit 510B.

[0203] Figure 17C shows a schematic diagram of the antenna 70 in some other embodiments. The difference between the antenna 70 shown in Figure 17A and the radiator 701 is that the radiator 701 also includes a grounding point D3, and the feed point P4 and the grounding point D3 are located at the two ends of the radiator 701 extending circumferentially.

[0204] Figure 17D shows a schematic diagram of the antenna 70 in some other embodiments. As shown in Figure 17D, in some embodiments, the annular frame 510 includes a first slit 510A and a second slit 510B, and the radiator 701 can be a first portion 5101 of the annular frame 510 between the first slit 510A and the second slit 510B. The first portion 5101 includes a first sub-portion 51011 and a second sub-portion 51012, and there is a slit between the first sub-portion 51011 and the second sub-portion 51012, within which an electronic component 703 (e.g., one or more of a switch, capacitor, and inductor) is coupled, that is, the electronic component 703 is coupled to the first sub-portion 51011 and the second sub-portion 51012 respectively. This antenna 70 has a large circumferential dimension and a large radiating aperture, which helps to improve the radiation performance of the antenna 70.

[0205] In some embodiments, electronic component 703 may be disposed on the circuit board of watch 3, with a first end of electronic component 703 coupled to a first sub-part 51011 and a second end of electronic component 703 coupled to a second sub-part 51012.

[0206] In some embodiments, the electronic component 703 may also be an equivalent capacitor or an equivalent inductor. For example, one of the first sub-parts 51011 and the second sub-parts 51012 on both sides of the fracture extends inward and forms a distributed capacitor (e.g., a parallel plate capacitor structure) with the other, or the first sub-parts 51011 and the second sub-parts 51012 extend inward respectively to form a distributed capacitor (e.g., a parallel plate capacitor structure). As another example, the first sub-parts 51011 and the second sub-parts 51012 on both sides of the fracture are coupled with one or more strip structures, which form a distributed inductor. The strip structures can be straight, bent, etc.

[0207] In some embodiments, a power supply circuit is connected to the power supply point P4, which can be used to receive and transmit radio frequency signals at the frequency corresponding to the walkie-talkie mode.

[0208] Alternatively, in other embodiments, the watch 3 may integrate a walkie-talkie function module (including an RF front-end chip and a transceiver), and the radiator 701 is electrically connected to the walkie-talkie function module through the feed point P4. The walkie-talkie function module is specifically used to receive and transmit RF signals in walkie-talkie mode.

[0209] In some embodiments, a matching circuit is also included between the power supply point P4 and the power supply circuit / walkie-talkie function module. The power supply point P4 and the matching circuit are used for frequency tuning of the corresponding frequency band of the walkie-talkie mode.

[0210] It is understood that in the above embodiments, the radial diameter of the floor 702 in the watch 3 is small (e.g., 40mm), resulting in low radiation efficiency of the radiator 701 when it operates in the walkie-talkie frequency band.

[0211] Based on this, in this embodiment of the application, when the watch 3 enters the walkie-talkie mode (antenna 70 operates at 400-410MHz), a guidance interface is displayed on the display screen 52 to guide the user to contact the location of the antenna 70 on the housing 51, for example, to contact the antenna 70 at the edge of the housing 51 as shown in Figure 16A, so as to improve the radiation efficiency of the antenna 70 and enhance the performance of the watch 3 in the walkie-talkie mode.

[0212] In some embodiments, the watch 3 can guide the user to contact the antenna 70 via a guide interface 800 as shown in FIG18A.

[0213] As shown in Figure 18A, when the watch 3 enters walkie-talkie mode, it displays interface 800, which includes guidance information 810 and a walkie-talkie voice control 820. For example, the guidance information 810 may include the guidance text "Finger touches the border" 810a and a pointing arrow 810b. The walkie-talkie voice control 820 is used to collect the user's voice upon detecting a user's click operation.

[0214] In another example of a guide interface 800, as shown in Figure 18B, the guide information 810 may include the guide text “Please touch here” 810a and the guide touch area 810c.

[0215] It is understandable that in the application scenario of Watch 3, human contact with any position on the radiator 701 can bring about an improvement in radiation efficiency. Therefore, the aforementioned pointing arrow 810b and the guiding contact area 810c can be defined according to the position of the radiator 701.

[0216] This application does not limit the specific content of the guidance information 810; anything used to guide the user to contact the antenna 70 falls within the scope of protection of this application. Furthermore, the contact with the antenna 70 mentioned in this application includes both direct and indirect contact. See the description above for details, which will not be repeated here.

[0217] In the application scenario of Watch 3, the preset area mentioned in this application can be the area of ​​the housing 51 that the user touches based on the guidance information (e.g., pointing arrows) in the guidance interface. For example, in Figure 18A, the preset area 51A on the housing 51 is indicated by the pointing arrow 810b. That is, the preset area in this application can refer to the area pointed to by the guidance information in the display interface.

[0218] Figure 19 shows a schematic diagram of the user's posture when touching the watch 3 based on the guidance information 810 shown in Figure 18A. As shown in Figure 19, by guiding the user to the location of the antenna 70 through the guidance information 810 displayed on the watch 3, the energy loss of the antenna 70 radiated by the user's arm wearing the watch 3 can be reduced, thereby improving the performance of the antenna 70 in walkie-talkie mode.

[0219] For ease of understanding, this application embodiment is based on the model diagram of the user wearing watch 3 on the left arm shown in Figure 20, and the antenna 70 radiation of watch 3 under the walkie-talkie module is simulated.

[0220] As shown in Figure 21(a), when the user's right hand fingers do not touch the antenna 70, the antenna 70 radiates into the left arm. However, as shown in Figure 21(b), when the user's right hand fingers touch the antenna 70 in the posture shown in Figure 19, the radiation absorption of the left arm is significantly reduced. Thus, the external radiation performance of the antenna 70 can be improved.

[0221] In this embodiment of the application, the performance of the antenna 70 was simulated and tested under different conditions: when the user's finger touches the antenna 70 and when the user's finger does not touch the antenna 70.

[0222] Figure 22 shows the antenna performance curves when the user's finger touches the antenna 70 and when the user's finger does not touch the antenna 70. Curve 1 represents the radiation efficiency when the user's finger touches the antenna 70, and curve 2 represents the radiation efficiency when the user's finger does not touch the antenna 70. As shown in Figure 22, in walkie-talkie mode, for example, when the antenna 70 operates at approximately 400MHz, the antenna radiation efficiency is -12.49dB when the user's finger touches the antenna 70, while it is -17.025dB when the user's finger does not touch the antenna 70. Therefore, it can be seen that touching the antenna 70 effectively improves the radiation efficiency.

[0223] As mentioned earlier, in the application scenarios of Watch 3, human contact with any position on the radiator 701 can bring about an improvement in radiation efficiency.

[0224] Based on the antenna 70 structure shown in Figure 17A, the antenna performance is simulated when a user's finger touches the four positions (A1 to A4) shown in Figure 23A. Figure 23B shows a schematic diagram of the antenna performance curves when a user's finger touches the four positions shown in Figure 23A. As shown in Figure 23B, in walkie-talkie mode, for example, when antenna 70 operates in the approximately 400MHz frequency band, the difference in radiation efficiency corresponding to different positions of the human body touching the radiator 701 is small.

[0225] In some embodiments, the guidance information in the guidance interface includes instructions on the number of fingers the user is touching. The number of fingers indicated can be one, two, three, four, or five fingers.

[0226] For example, as shown in Figure 24, which illustrates a schematic diagram of interface 800 in some other embodiments. As shown in Figure 24, the guidance text "Please touch the border with three fingers" 810a in the guidance information 810 indicates the number of fingers the user should touch.

[0227] Figure 25 shows a schematic diagram of the user's posture when touching the watch 3 based on the guidance information 810 shown in Figure 24. As shown in Figure 24, by guiding the user to touch the location of the antenna 70 with three fingers through the guidance information 810, the contact area between the fingers and the antenna 70 can be increased, reducing the loss of radiated energy from the antenna 70 by the user's arm wearing the watch 3, thereby improving the performance of the antenna 70 in walkie-talkie mode.

[0228] Figure 26A shows a schematic diagram of the antenna performance when one finger touches antenna 70 as shown in Figure 20. Figure 26B shows a schematic diagram of the antenna performance when three fingers touch antenna 70 as shown in Figure 25. As can be seen from Figure 26A, the radiation efficiency of antenna 70 is -11.7 dB when one finger touches it. As can be seen from Figure 26B, the radiation efficiency of antenna 70 is -9.9 dB when three fingers touch it. It can be seen that the more fingers that touch it, that is, the larger the contact area, the higher the radiation efficiency of antenna 70.

[0229] In some embodiments, the guidance information in the guidance interface also includes instructions on the angle at which the user's finger contacts the antenna 70. For example, Figures 27A and 27B illustrate two different angles. As shown in Figure 27A, the user contacts the antenna 70 with a single finger at an angle further away from the left arm (hereinafter referred to as angle 1). As shown in Figure 27B, the user contacts the antenna 70 with a single finger at an angle closer to the left arm (hereinafter referred to as angle 2).

[0230] In some embodiments, the guidance information in the guidance interface can present the arm posture shown in Figure 27A or Figure 27B as an image.

[0231] Figure 28 shows the antenna performance when the user's finger is not in contact with the antenna 70 and when the finger is in contact with the antenna 70 at angles 1 and 2. As shown in Figure 28, when the antenna 70 operates in the approximately 400MHz frequency band, the radiation efficiency is -10.617dB when the user's finger is in contact with the antenna 70 at angle 1, -12.545dB when the user's finger is in contact with the antenna 70 at angle 2, and -16.962dB when the user's finger is not in contact with the antenna 70. It can be seen that the antenna performance is improved when the user's finger is in contact with the antenna 70 at angle 1 or angle 2 compared to when the user's finger is not in contact with the antenna 70, and the performance is best when the user's finger is in contact with the antenna 70 at angle 1. That is, when the user's right hand touches the edge of the housing 51, the wider the angle between the right hand and the left arm, the better the radiation efficiency of the antenna 70.

[0232] Figure 29 shows a schematic diagram of the structure of the antenna 70 in some other embodiments.

[0233] In some embodiments, as shown in FIG29, the radiator 701 of the antenna 70 surrounds the floor 702 circumferentially. That is, the radiator 701 can be a complete annular frame 510, which may not include gaps. The radiator 701 may include feed points, and this application does not limit the number or location of feed points. The radiator 701 may include grounding points, and this application does not limit the number or location of grounding points.

[0234] Figure 30A shows a schematic diagram of the antenna performance curves when the user's finger is not in contact with the antenna 70 shown in Figure 29. Curve 1 indicates that the antenna 70 has a resonant frequency of approximately 400MHz, and curve 2 indicates the radiation efficiency when the user's finger is not in contact with the antenna 70. As can be seen from curve 2, when the antenna 70 operates at approximately 400MHz, the radiation efficiency when the user's finger is not in contact with the antenna 70 is -22.69dB.

[0235] Figure 30B shows a schematic diagram of the antenna performance curves when a user's finger touches the antenna 70 shown in Figure 29. Curve 1 indicates that the antenna 70 has a resonant frequency of approximately 400MHz, and curve 2 indicates the radiation efficiency when the user's finger touches the antenna 70. As can be seen from curve 2, when the antenna 70 operates at approximately 400MHz, the radiation efficiency when the user's finger touches the antenna 70 is -19.2dB.

[0236] It is understandable that, based on testing and simulation, for the antenna 70 structure shown in Figure 29, in walkie-talkie mode, the radiation performance of the antenna 70 can be improved by the user's finger touching any edge of the casing 51. Correspondingly, the guidance interface can adopt an interface 800 similar to those shown in Figures 18A, 18B, or 24. Furthermore, the radiation performance of the antenna 70 can be improved by the user touching the watch 3 with any contact posture shown in Figures 19, 25, 27A, or 27B based on the guidance interface.

[0237] Furthermore, the above embodiment uses a circular dial body 50 as an example. As mentioned earlier, the dial body 50 can be rectangular. Below, using a rectangular dial body 50 as an example, some other forms of the radiator 701 will be described.

[0238] As shown in Figure 31A, the floor 702 is rectangular. The radiator 701 is elongated and extends along the length or width of the surface 50, with a gap between the radiator 701 and the floor 702. The radiator 701 may include a power supply point; the number and location of the power supply points are not limited in this application. The radiator 701 may include a grounding point; the number and location of the grounding points are not limited in this application.

[0239] As shown in Figure 31B, the difference from that shown in Figure 31A is that the radiator 701 is L-shaped and located at the corner of the surface 50, such as the upper left corner, the upper right corner, the lower left corner, or the lower right corner. This application does not limit this.

[0240] As shown in Figure 31C, the radiator 701 is in the shape of a rectangular ring and is arranged at intervals around the floor 702.

[0241] It is understandable that, based on testing and simulation, for the antenna 70 structure shown in Figures 31A to 31C, in walkie-talkie mode, the radiation performance of the antenna 70 can be improved by the user's finger touching the location of the antenna 70 on the housing 51. Correspondingly, the guidance interface can adopt an interface 800 similar to those shown in Figures 18A, 18B, or 24. Furthermore, the radiation performance of the antenna 70 can be improved by the user touching the watch 3 with any contact posture shown in Figures 19, 25, 27A, or 27B based on the guidance interface.

[0242] In some embodiments, as shown in Figures 17A to 17D and Figure 29, the diameter of the circular annular frame 510 ranges from 36 mm to 44 mm; exemplary examples, it can be 38 mm, 42 mm, or 44 mm. Since the radiator 701 can be the entire annular frame 510 or a part of it, the physical length of the radiator 701 can be... Where d is the diameter of the annular border 510.

[0243] Alternatively, as shown in Figure 16B, for the rectangular annular frame 510, the length of its dimensions ranges from 42 mm to 46 mm, for example, 44.5 mm, and the width of its dimensions ranges from 36 mm to 42 mm, for example, 40 mm. Correspondingly, since the radiator 701 can be the entire annular frame 510 or a part of the annular frame 510, the physical length of the radiator 701 can be the length of the annular frame 510, the width of the annular frame 510, or its perimeter; that is, the physical length of the radiator 701 can be from 36 mm to 176 mm.

[0244] This application provides an interface display method applied to an electronic device. Figure 32 shows a flowchart of the interface display method according to this application. As shown in Figure 32, the interface display method includes the following steps:

[0245] S3201: Electronic device detected to have entered walkie-talkie mode.

[0246] In some embodiments, the electronic device detects a user operation and determines that it has entered walkie-talkie mode. The user operation includes, but is not limited to, voice commands, gesture commands, or touch operations based on the walkie-talkie application interface (which may include trigger controls for walkie-talkie mode).

[0247] As mentioned above, electronic devices reuse antennas to implement walkie-talkie functions. For example, the operating frequency of the antenna corresponding to the walkie-talkie mode can be 400–410 MHz (the range of the second operating frequency band mentioned in this application). In some embodiments, electronic devices can reuse antennas in the 699–960 MHz frequency band (the range of the first operating frequency band mentioned in this application) to implement walkie-talkie functions.

[0248] Generally, the electrical length of an antenna in the 699–960 MHz band can be one-quarter of the wavelength corresponding to the resonant frequency within that band. For example, the physical length of the radiator of an antenna in the 699–960 MHz band is approximately 4–11 cm. For instance, the physical length of the radiator can be 4 cm, 5 cm, 8 cm, 10 cm, or 11 cm.

[0249] S3202: Display the first interface, which includes guidance information to guide the user to the location of the antenna in the electronic device.

[0250] It is understood that the first interface is the guidance interface mentioned in this application, such as interface 400 shown in Figure 4A or Figure 4B, interface 800 shown in Figure 18A, Figure 18B, or Figure 24. The guidance information may include one or more of the following: information for instructing the user on the grip posture when touching the casing; information for instructing the user on the arm posture when touching the casing; information for instructing the area of ​​the user touching the casing; and information for instructing the number of fingers of the user touching the casing.
