[0003] In related technologies, due to the limited internal space of electronic devices and the increasing number of antennas, it is difficult to improve the antenna performance of some antennas, which is not conducive to improving the communication performance of electronic devices. Utility Model Content

[0004] This disclosure provides a radiating arm, an antenna assembly, and an electronic device.

[0041] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this disclosure.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0043] For ease of understanding and explanation, some of the terms and technical terms that appear in the embodiments below this specification are explained.

[0044] Coupling can be understood as direct coupling and / or indirect coupling. "Coupled connection" can be understood as a direct coupling connection and / or indirect coupling connection. Direct coupling can also be called "electrical connection," which is understood as physical contact and electrical conduction between components; it can also be understood as the form of connection between different components in a circuit structure through physical lines that can transmit electrical signals, such as copper foil or wires on a printed circuit board (PCB). "Indirect coupling" can be understood as two conductors conducting electricity through a gap / non-contact method. In one embodiment, indirect coupling can also be called capacitive coupling, for example, signal transmission is achieved by forming an equivalent capacitance through coupling between the gaps between two conductive components.

[0045] Capacitor: can be understood as lumped capacitance and / or distributed capacitance. Lumped capacitance refers to capacitive components, such as capacitor elements; distributed capacitance (or distributed capacitance) refers to the equivalent capacitance formed by two conductive components separated by a certain gap.

[0046] Inductance: can be understood as lumped inductance and / or distributed inductance. Lumped inductance refers to inductive components, such as inductor elements; distributed inductance (or distributed inductance) refers to the equivalent inductance formed through a conductive element of a certain length, such as the equivalent inductance formed by a conductor due to bending or rotation.

[0047] A radiator, or antenna stub, is a device in an antenna 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 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.

[0048] Radiators (or antenna stubs) may include conductors with specific shapes and sizes, such as wires or sheets, and this application does not limit the specific shape. In one embodiment, a wire radiator may be simply referred to as a wire antenna. In one embodiment, a wire radiator may be implemented by a conductive frame, and may also be referred to as a frame antenna. In one embodiment, a 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 loop antennas, half-wave dipole antennas, monopole antennas, ring antennas, and inverted F antennas (also known as inverted F antennas). For example, in a loop antenna, each loop antenna typically includes two radiating stubs, each fed from the feed end of the radiating stub by a feed section. For example, an inverted-F antenna can be considered as a monopole antenna with an added ground path. An inverted-F antenna 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. 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 ring-shaped 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.

[0049] Radiators (or antenna stubs) 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, which is spaced apart from the ground and grounded at both ends, thereby forming a closed or semi-closed slot or gap.

[0050] A radio frequency (RF) module, also called a power supply circuit, is a combination of all circuits used for receiving and transmitting radio frequency (RF) signals. An RF module can include a transceiver and an RF front-end. In some narrower senses, "RF module" refers to an RF chip (RFIC), which can be considered to include both the RF front-end chip and the transceiver. An RF module has the function of converting radio waves (e.g., RF signals) into electrical signals (e.g., digital signals). It is generally considered the RF component.

[0051] In some embodiments, the electronic device may also include a test socket (or, RF socket or RF test socket). This test socket can be used to insert a coaxial cable to test the characteristics of the RF front-end circuitry or the radiator of the antenna. The RF front-end circuitry can be considered as the circuitry coupled between the test socket and the transceiver.

[0052] In some embodiments, the radio frequency front-end circuit can be integrated into a radio frequency front-end chip in an electronic device, or the radio frequency front-end circuit and the transceiver can be integrated into a radio frequency chip in an electronic device.

[0053] A matching circuit is a circuit associated with adjusting the radiation characteristics of an antenna. In one embodiment, the matching circuit is coupled between the RF module and the corresponding radiator. Typically, the matching circuit is coupled between the test mount and the radiator. In one embodiment, the matching circuit has impedance matching and / or frequency tuning functions. It is generally considered part of the antenna.

[0054] A tuning circuit is a circuit associated with adjusting the resonant frequency of an antenna. In one embodiment, the tuning circuit is coupled between the radiator and the ground. In another embodiment, the tuning circuit is coupled between the radio frequency module and the radiator. In yet another embodiment, the tuning circuit functions as impedance matching and / or frequency tuning. Typically, it is considered part of the antenna.

[0055] In one embodiment, the matching circuit / tuning circuit may include switches and / or electronic components / devices, where the switches are electronic components / devices for switching the coupling connection of the radiator. The switches in the matching circuit / tuning circuit may also be referred to as antenna switches. In one embodiment, the matching circuit / tuning circuit may include a filter circuit.

[0056] Ground / Plug: This can broadly refer to at least a portion of any grounding layer, ground plane, or ground 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 / Plug" can be used for grounding components within an electronic device. In one embodiment, "Ground / Plug" may include any one or more of the following: a grounding layer of the electronic device's circuit board, a ground plane formed by the frame of the electronic device, a ground metal layer formed by a thin metal film beneath the screen, a conductive grounding layer of the battery, and conductive or metallic components electrically connected to the aforementioned grounding layer / ground plane / metal layer. In one embodiment, the circuit board may be a printed circuit board. In one embodiment, components such as a display, touchscreen, input button, transmitter, processor, memory, battery, charging circuit, and system-on-chip (SoC) architecture may be mounted on or connected to the circuit board; or electrically connected to the trace layers and / or grounding layers in the circuit board. For example, a radio frequency source is disposed on a trace layer.

[0057] 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.

[0058] Grounding: refers to coupling with the aforementioned ground / floor via a grounding structure and / or grounding circuit. In one embodiment, grounding can be achieved through physical grounding, such as through a structural component of the mid-frame to achieve physical grounding at a specific location on the frame (or, physical ground). In another embodiment, grounding can be achieved through device grounding, such as through devices like capacitors / inductors / resistors connected in series or parallel (or, device ground).

[0059] End / Point: The "end / point" in the first end / second end / feed end / ground end / feed point / ground point / connection point of an antenna radiator should not be narrowly interpreted as necessarily an endpoint or end that is physically disconnected from other radiators. It can also be considered as a point or segment on a continuous radiator. In one embodiment, an "end / point" may include a connection / coupling region on the antenna radiator that is coupled to other conductive structures. For example, a feed end / feed point may be a coupling region on the antenna radiator that is coupled to a feed structure (e.g., a region facing a part of the feed structure). Similarly, a ground end / ground point may be a connection / coupling region on the antenna radiator that is coupled to a ground structure.

[0060] 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).

[0061] Wide beams have a widened wavefront in space, a larger beam angle, and a wider coverage area.

[0062] Wide-beam antennas refer to antenna designs with wide-angle beam coverage characteristics. Their half-power beamwidth (HPBW) typically exceeds 120°, enabling them to maintain stable alignment in dynamic communications between electronic devices and high-speed satellites.

[0063] Currently, mobile phones, tablets, and other electronic devices have become indispensable technological products in people's lives, studies, and entertainment, bringing them numerous conveniences and enjoyment. With the diversification of electronic device functions, there are now many types and brands available, offering consumers a wide range of choices. Simply improving the functional features of electronic devices is no longer sufficient to meet people's demands.

[0064] With the continuous development of communication technology, the number of antennas in electronic devices is also increasing. To address this, electronic devices often use a combination of various antenna types, such as metal frame antennas and LDS / FPC antennas, to achieve coverage across a wide range of frequency bands and scenarios. LDS / FPC antennas have small profiles and high space utilization. They can achieve good signal radiation performance using only metal traces, making them a promising antenna design with a large market and promising future.

[0065] However, in related technologies, people have increasingly higher requirements for the antenna performance of electronic devices, and the communication performance of traditional LDS / FPC antennas can no longer meet people's requirements for communication performance.

[0066] Based on this, the present disclosure provides a radiating arm. This radiating arm forms a current loop for the gain radiating stub through structural optimization. When applied to antenna components and electronic devices, the current loop effectively enhances the communication performance of the gain radiating stub.

[0067] To better understand the radiating arm of this disclosure, it is illustrated by an electronic device in which the radiating arm is applied.

[0068] like Figure 1 As shown, in some embodiments, an electronic device 10 is provided, including an antenna assembly 100, a housing assembly 200, and a radio frequency module 300. The radio frequency module 300 is disposed in the housing assembly 200 and is fed in conjunction with a power supply section 1111.

[0069] The antenna assembly 100 includes a radiating arm 110 and an insulating member 120 disposed on the housing assembly 200. The radiating arm 110 is fixed to the insulating member 120. The radiating arm 110 includes a first radiating branch 111, a second radiating branch 112, and a current loop 113. The first radiating branch 111 has a feed section 1111. The second radiating branch 112 is bent and connected to the first radiating branch 111, and the second radiating branch 112 has a grounding section 1121 spaced apart from the feed section 1111. The current loop 113 has a first through hole 1131. The current loop 113 is electrically connected to both the first radiating branch 111 and the second radiating branch 112, and at least a portion of the current loop 113 is disposed between the feed section 1111 and the grounding section 1121.

[0070] When the electronic device 10 is in use, the antenna assembly 100 is flexibly mounted on the housing assembly 200 via the insulating member 120. The radio frequency module 300 is mounted on the housing assembly 200 and is fed in conjunction with the feed section 1111. It can excite the electromagnetic field generated by the current loop 113 to superimpose the electromagnetic field generated between the first radiating branch 111 and the second radiation, thereby achieving the effect of radiation superposition enhancement and thus achieving the purpose of antenna performance enhancement.

[0071] In some embodiments, the radiating arm 110 is made of LDS (Laser Direct Structuring) or a patch, and the insulating component 120 is an insulating support. Thus, when the radiating arm 110 is made of LDS, the antenna assembly 100 constitutes an LDS antenna, occupying less space and making the structure of the electronic device 10 more compact. When the radiating arm 110 is made of a patch, the antenna assembly 100 constitutes a patch antenna.

[0072] In some embodiments, the insulating element 120 is made of a flexible material and cooperates with the radiating arm 110 to form an FPC antenna. In this way, the antenna can be formed on a flexible circuit board, which facilitates wiring, occupies less space, and makes the structure of the electronic device 10 more compact.

[0073] In some embodiments, the insulating element 120 is a circuit board substrate, and the radiating arm 110 is a conductive foil. In this way, the desired antenna can be formed on the circuit board.

[0074] like Figure 2 As shown, in some embodiments, the radiating arm 110 is further provided with a plurality of second through holes 101 arranged around the current ring 113, and the insulating member 120 is provided with a protrusion 121 that nests and engages with the second through holes 101. In this way, the engagement between the second through holes 101 and the protrusion 121 facilitates the reliable fixing of the radiating arm 110 to the insulating member 120.

[0075] In conjunction with the aforementioned patch embodiment, the radiating arm 110 can be easily injection molded with the insulating component 120 through the second through hole 101, so that part of the insulating component is embedded in the second through hole 101, forming a protrusion 121 that is nested and fitted with the second through hole 101.

[0076] like Figure 2 As shown, in some embodiments, the insulating member 120 is provided with a third through hole 122 that corresponds one-to-one with the first through hole 1131 to form a first clearance through hole. Thus, the insulating member 120 can be used as a decorative element for a camera, which passes through the first clearance through hole to obtain light from outside the electronic device 10. The insulating member 120 can also be used as a light shield to prevent stray light from entering the image sensor and affecting the image quality of the electronic device 10.

[0077] like Figure 2 As shown, in some embodiments, the first radiating branch 111 is further provided with clearance slots spaced apart from the first through hole 1131 along the length direction of the first radiating branch 111, and the insulating member 120 is provided with a fourth through hole 122 that corresponds one-to-one with the clearance slot to form a second clearance through hole. Thus, the insulating member 120 can be used as a decorative element for a camera, which passes through the second clearance through hole to obtain light from outside the electronic device 10. The insulating member 120 can also be used as a light shield to prevent stray light from entering the image sensor and affecting the image quality of the electronic device 10.

[0078] In conjunction with the aforementioned embodiment of the first bypass through hole, two cameras can be integrated using the insulating member 120, which facilitates providing users with more shooting experiences.

[0079] At least a portion of the current loop 113 is positioned close to the feed section 1111. In this way, the current generated by the feed section 1111 can be used to excite the current loop 113 to generate an electromagnetic field, thereby increasing the radiation performance of the radiation arm 110.

[0080] like Figure 2As shown, in some embodiments, the first radiating stub 111 includes a first end 1112 that is bent and connected to one end of the second radiating stub 112, and a second end 1113 that is spaced apart from the first end 1112 along a first direction. The feed section 1111 and the current loop 113 are disposed near the first end 1112, and the ground section 1121 is disposed near the other end of the second radiating stub 112. At least a portion of the current loop 113 is disposed between the feed section 1111 and the ground section 1121. Thus, the first radiating stub 111 and the second radiating stub 112 can easily form an inverted-F antenna. By placing the current loop 113 as close as possible to the feed section 1111 and the ground section 1121, it is convenient to use the ground section 1121 to excite the current loop 113 to generate an electromagnetic field. The current loop 113 is closer to the feed section 1111 than the second end 1113, which facilitates the superposition of the radiated fields to enhance the radiation performance of the inverted-F antenna and improve the communication performance of the electronic device 10.

[0081] Furthermore, in some embodiments, the current loop 113 is positioned close to the ground portion 1121 and spaced apart from the second end 1113 along a first direction. This positions the current loop 113 close to the ground portion 1121. The stronger current at these locations results in a stronger radiation field generated by the current loop 113, further enhancing the radiation performance of the antenna assembly 100.

[0082] like Figure 2 As shown, in some embodiments, at least a portion of the second radiating stalk 112 extends along a second direction, which is perpendicular to the first direction. This facilitates the formation of an inverted-F antenna.

[0083] like Figure 2 As shown, the first direction is the X-axis direction, and the second direction is the Y-axis direction.

[0084] In some embodiments, the first radiating branch 111, the second radiating branch 112, and the current loop 113 are integrally formed. This reduces assembly steps, improves the precision of the radiating arm 110, and helps to improve its radiation performance.

[0085] In some embodiments, the current loop 113 includes at least two loops, which are spaced apart along the length of the first radiating stub 111. This allows for the flexible arrangement of multiple current loops 113 to enhance the radiating stub and improve the radiation performance of the radiating arm 110, depending on actual needs.

[0086] like Figure 3As shown, in some embodiments, when the power supply section 1111 is powered, the current generated by the first radiating branch 111 flows to the second terminal 1113, and the current generated by the grounding section 1121 flows around the current loop 113 to the power supply section 1111 and the second terminal 1113, respectively. In this way, the current loop 113 can induce an equivalent electromagnetic field, thereby enhancing the radiation performance of the first radiating branch 111 and the second radiating branch 112 through the principle of field superposition.

[0087] like Figure 4 As shown, in some embodiments, the first radiating stub 111 and the second radiating stub 112 cooperate to form an inverted-F radiator. Thus, after the feed section of the radiating arm is energized, it can excite the first and second radiating stubs to form an inverted-F antenna, also called an IFA antenna, which can generate two electric field components, Ex and Ey. The electric field of the current loop, Etotal, can be decomposed into an Ex1 electric field component and an Ey2 electric field component.

[0099] In the description of this disclosure, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0100] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include at least one of that feature. In the description of this disclosure, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0101] In this disclosure, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0102] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0103] It should be noted that when a component is referred to as "fixed to," "set on," "fixed to," or "mounted on" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component. Furthermore, when a component is considered to be "fixed transmission connection" to another component, the two can be fixed in a detachable or non-detachable manner, as long as power transmission can be achieved. Methods such as socketing, snap-fitting, integral molding, and welding are feasible in conventional technologies and will not be elaborated upon here. When a component is perpendicular or approximately perpendicular to another component, it means that the ideal state is perpendicularity, but due to manufacturing and assembly factors, a certain degree of perpendicularity error may exist. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only and do not represent the only possible implementation.

[0104] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0105] The above embodiments are merely illustrative of several implementation methods of this disclosure, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent.
