Description

Technical Field

[0001] This application relates to the field of antenna device technology, and in particular to an antenna device and electronic device. Background Technology

[0002] With the development of communication technology, wireless mobile devices are becoming increasingly common, especially mobile phones. People are no longer satisfied with simple call functions; they are increasingly seeking miniaturization and improved communication quality in mobile communication devices such as mobile phones. As a crucial component for communication quality, the development of antenna devices is receiving more and more attention.

[0003] Taking a mobile phone as an example, the antenna device is embedded in the phone and includes a grounding component and a feed component electrically connected to the grounding component. In related technologies, antenna devices generally have a radiation area. When the antenna is working, the signal enters the antenna through the feed component, which excites a current distribution in the radiation area. The antenna radiates the electromagnetic energy carried by the current in the form of electromagnetic waves through the radiation area, realizing signal transmission (for transmitting antennas). During reception, external electromagnetic waves induce a current signal in the radiation area, which is transmitted to subsequent circuits for processing through the feed component (for receiving antennas).

[0004] However, the antenna devices in the relevant technologies cannot cover multiple frequency bands well. Utility Model Content

[0042] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0043] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application.

[0044] Furthermore, where the terms "first" and "second" appear, these terms are 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" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0045] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0046] In related technologies, gaps are incorporated into antenna devices to divide them into multiple radiation regions. The presence of these gaps alters the antenna's equivalent inductance and capacitance. Since the antenna's resonant frequency is related to its equivalent inductance and capacitance, the position, size, and shape of these gaps can be appropriately adjusted to modify the antenna's equivalent inductance and capacitance, thereby ensuring the antenna's resonant frequency meets the requirements of a specific operating frequency band. For example, in antennas requiring multi-band operation, multiple different gaps are used to achieve resonance in different frequency bands.

[0047] However, in related technologies, the arrangement of multiple radiation zones cannot adequately cover multiple different frequency bands.

[0048] To address the aforementioned problems, embodiments of this application provide an antenna device and electronic device. By including a first resonant adjustment unit and a second resonant adjustment unit, the antenna radiating element is divided into multiple first radiating arms spaced apart along a second direction. This arrangement of the multiple first radiating arms forms a radiating array, capable of generating resonance at multiple different frequencies. These resonant frequencies mutually increase, enabling the antenna to achieve effective electromagnetic radiation and reception over a wider frequency range, thereby broadening the antenna's operating frequency band and generating a wider bandwidth, maximizing the performance across the entire 4G frequency band from 700MHz to 2700MHz.

[0049] The following will combine Figures 1 to 4 The specific structures of the antenna device and electronic device provided in the embodiments of this application will be described.

[0050] This application provides an electronic device including a housing, with an antenna device at least partially exposed within the housing. This allows the antenna to interact more directly with external electromagnetic fields, thereby enhancing signal reception and transmission capabilities, improving the communication quality of the electronic device, and also facilitating heat dissipation within the electronic device.

[0051] For example, the electronic device can be a mobile phone, laptop computer, tablet computer, etc. This embodiment does not limit this.

[0052] Reference Figure 1 and Figure 2 As shown, this application embodiment provides an antenna device, including a substrate 100 and an antenna radiating element 200, the antenna radiating element 200 being disposed on the substrate 100. It can be understood that the substrate 100 can also be referred to as a motherboard.

[0053] For example, the connection method between the antenna radiating element 200 and the substrate 100 is not limited. For instance, the antenna radiating element 200 can be soldered onto the substrate 100; or the antenna radiating element 200 and the substrate 100 can be connected by means of snap-fit, screw connection, etc. This embodiment does not limit this.

[0054] In this embodiment, refer to Figure 3 As shown, the antenna radiating element 200 includes a feed element 210, a grounding element 220 and an antenna radiating element 230. The feed element 210 is electrically connected to the feed point of the substrate 100; the grounding element 220 is electrically connected to the grounding point of the substrate 100; and the antenna radiating element 230 is electrically connected to both the feed element 210 and the grounding element 220.

[0055] It should be noted that the basic working principle of the antenna device is as follows: when the feed element 210 introduces a radio frequency signal into the antenna radiator 230, a current distribution is generated on the antenna radiator 230. According to Maxwell's equations, a changing current generates a changing magnetic field, which in turn generates a changing electric field, thus forming electromagnetic waves that radiate outward in the space surrounding the antenna. The grounding element 220 acts as a reference potential, providing a loop for the current in the antenna radiator 230, allowing the current to flow continuously within the antenna radiator 230.

[0056] In this embodiment, refer to Figure 1 As shown, the antenna radiator 230 may be provided with a first resonance adjustment part 231 and a second resonance adjustment part 232. The first resonance adjustment part 231 and at least part of the second resonance adjustment part 232 both extend along the first direction X and divide the antenna radiator 230 into a plurality of first radiating arms 240 arranged at intervals along the second direction Y; the first direction and the second direction intersect.

[0057] For example, the first direction X can be the length direction of the antenna radiating element 200, that is, in this embodiment, the first direction X is the horizontal direction, and the second direction Y can be the height direction of the antenna radiating element 200. It should be noted that the length, width, and thickness in this embodiment are merely for ease of description and do not imply any limitation on the dimensions.

[0058] In this embodiment, the first resonance adjustment part 231 and at least part of the second resonance adjustment part 232 are both extended along the first direction X (horizontal direction), which helps to change the current distribution path on the antenna radiator 230, so that the antenna can resonate at multiple different frequencies, and the different resonance frequencies are superimposed on each other, thereby widening the operating frequency band of the antenna.

[0059] In addition, the horizontally extended resonance adjustment makes the current distribution of the antenna radiator 230 more uniform and controllable in the horizontal direction. At the same time, it allows the antenna to be relatively small in the vertical direction, thus realizing the antenna layout in a limited space. For space-constrained electronic devices, this helps to achieve miniaturization and thinning of the device, and also reduces the manufacturing difficulty.

[0060] In this embodiment, multiple first radiating arms 240 are arranged at intervals along the second direction Y. On the one hand, this forms a radiating array capable of resonating at multiple different frequencies. These resonant frequencies mutually increase each other, enabling the antenna to achieve effective electromagnetic radiation and reception over a wider frequency range, thereby broadening the antenna's operating frequency band and generating a wider bandwidth to maximize the 4G full-band performance of 700MHz-2700MHz. On the other hand, the layered design allows the first resonant adjustment unit 231 to be responsible for radiation in one frequency band, and the second resonant adjustment unit 232 to be responsible for radiation in another frequency band. Furthermore, due to their different spatial positions, mutual interference between different frequency bands is reduced, thereby achieving wider frequency band coverage and better frequency band isolation, and improving the overall performance of the antenna.

[0061] In some embodiments, reference is made to Figure 2 As shown, along the second direction Y, the antenna radiator 230 has a first side 233 and a second side 234 opposite to both ends of the central axis, and the second side 234 is connected to the substrate 100. The first resonance adjustment part 231 is disposed near the first side 233 relative to the central axis, and at least a portion of the second resonance adjustment part 232 is disposed near the second side 234 relative to the central axis.

[0062] It should be noted that the central axis is the middle position of the antenna radiator 230 in the height direction. For example, the middle position is at 1 / 2 in the height direction.

[0063] For example, with the substrate 100 as a plane, the position of the first resonance adjustment portion 231 is higher than at least a portion of the second resonance adjustment portion 232. That is, the first resonance adjustment portion 231 is closer to the outer side.

[0064] In this way, on the one hand, the arrangement of the first resonant adjustment part 231 on the outside can, to a certain extent, protect the second resonant adjustment part 232 on the inside and the components on the substrate 100; on the other hand, since the first resonant adjustment part 231 is on the outside, it is easier to operate and modify it when debugging and optimizing the antenna. For example, if the performance of a certain frequency band is found to be unsatisfactory during the test, it is easier to fine-tune the shape, size and other parameters of the first resonant adjustment part 231 without having to modify the complex structure inside the antenna near the substrate 100, which reduces the difficulty and cost of debugging and improves the efficiency of antenna design and production.

[0065] In some embodiments, reference is made to Figure 2 As shown, at least a portion of the second resonance adjustment unit 232 can be disposed on the central axis. That is, at least a portion of the second resonance adjustment unit 232 is located in the middle position.

[0066] In this way, on the one hand, the antenna can radiate more evenly in the horizontal and vertical directions, reducing blind spots and weak areas of signal coverage; on the other hand, the middle position maintains a certain distance from the top and bottom of the antenna radiating element 230, which can reduce unnecessary electromagnetic coupling between the antenna edge or other components, help reduce electromagnetic interference, avoid problems such as resonant frequency shift and bandwidth narrowing caused by strong coupling, and ensure the stable operation of the antenna in complex electromagnetic environments.

[0067] In some embodiments, reference is made to Figure 2 As shown, along the second direction Y, the ratio of the height of the first resonant adjustment part 231 to the height of the antenna radiator 230 is H1, where H1 is between 0.7 and 0.75.

[0068] For example, H1 can be set to 0.7, 0.71, 0.72, 0.73, 0.74, 0.75, or any value between 0.7 and 0.75, depending on actual needs. In this embodiment, H1 is mainly used as an example of 0.72 for illustration.

[0069] If H1 is less than 0.7, the first resonant adjustment part 231 is too close to the top of the antenna device, and the electromagnetic coupling between the first resonant adjustment part 231 and the edge of the top of the antenna or other structures will be enhanced, which may lead to unnecessary electromagnetic interference. This interference will affect the normal operation of the antenna, causing the resonant frequency of the antenna to shift, the bandwidth to narrow, and the radiation efficiency to decrease, thereby seriously affecting the performance of the antenna.

[0070] If H1 is greater than 0.75, the first resonant adjustment unit 231 is positioned relatively low in the antenna height direction, resulting in inefficient use of space in the antenna height direction. This may lead to underutilization of the upper space of the antenna and overcrowding of the lower space, affecting the overall structural layout of the antenna. This not only hinders the miniaturization design of the antenna but may also increase electromagnetic interference between the antenna and other devices, reducing the performance of the entire system.

[0071] Therefore, limiting H1 to between 0.7 and 0.75 ensures that the first resonance adjustment unit 231 is positioned appropriately in the antenna height direction, effectively adjusting the electromagnetic distribution inside the antenna and enabling the antenna to achieve a more ideal resonance within the operating frequency band.

[0072] In some embodiments, the ratio of the height of the second resonant adjustment unit 232 to the height of the antenna radiator 230 along the second direction is H2, where H2 is between 0.41 and 0.46. For example, in this embodiment, H2 is 0.435, which ensures that the second resonant adjustment unit 232 is positioned appropriately in the antenna height direction.

[0073] In some embodiments, reference is made to Figure 2 and Figure 4 As shown, the second resonance adjustment section 232 may include a first resonance adjustment segment 2321, a second resonance adjustment segment 2322, and a third resonance adjustment segment 2323; the third resonance adjustment segment 2323 extends along a first direction, and the first resonance adjustment segment 2321 and the second resonance adjustment segment 2322 are connected at opposite ends of the third resonance adjustment segment 2323; the first resonance adjustment segment 2321 and the second resonance adjustment segment 2322 both extend along a second direction and on the side away from the substrate 100, and are located on both sides of the first resonance adjustment section 231.

[0074] The above design allows different adjustment segments to excite specific resonant modes on different frequency bands, thereby expanding the antenna's multi-band resonant capability and enabling the antenna to support more communication frequency bands.

[0075] The first resonant adjustment section 2321 and the second resonant adjustment section 2322 are located on both sides of the first resonant adjustment section 231, which can effectively increase the isolation between different frequency bands. Different adjustment sections can work independently on different frequency bands, reducing mutual interference between frequency bands and ensuring the stability and reliability of the antenna when it works simultaneously on multiple frequency bands.

[0076] In some embodiments, reference is made to Figure 4 As shown, the orthographic projection of the third resonant adjustment section 2323 onto the plane of the substrate 100 covers and extends beyond the orthographic projection of the first resonant adjustment section 231 onto the plane of the substrate 100.

[0077] It is understandable that "coverage" means that the orthographic projection of the third resonant adjustment section 2323 on the plane where the substrate 100 is located completely includes the orthographic projection of the first resonant adjustment section 231 on the plane where the substrate 100 is located, that is, the projection of the first resonant adjustment section 231 is completely within the range of the projection of the third resonant adjustment section 2323.

[0078] "Exceeding" means that the projected area of ​​the third resonant adjustment section 2323 is larger than the projected area of ​​the first resonant adjustment section 231. It should be noted that there is no limit to the area of ​​the third resonant adjustment section 2323 exceeding the first resonant adjustment section 231, and it can be designed according to the actual antenna device.

[0079] This design allows the third resonant adjustment section 2323 to have a wider electromagnetic coupling area with the first resonant adjustment section 231 in space. This larger coupling range can more effectively adjust the current distribution on the antenna radiator 230, thereby enhancing the ability to control the antenna resonant characteristics.

[0080] In some embodiments, reference is made to Figure 1 and Figure 4As shown, the antenna radiator 230 may be provided with a third resonance adjustment part 235, a fourth resonance adjustment part 236 and a fifth resonance adjustment part 237; the third resonance adjustment part 235 is connected to the end of the first resonance adjustment section 2321 away from the third resonance adjustment section 2323, the fifth resonance adjustment part 237 is connected to the end of the second resonance adjustment section 2322 away from the third resonance adjustment section 2323; the fourth resonance adjustment part 236 is connected to the first resonance adjustment part 231.

[0081] Among them, the third resonance adjustment unit 235, the fourth resonance adjustment unit 236 and the fifth resonance adjustment unit 237 divide the antenna radiator 230 into a plurality of second radiating arms 250 arranged at intervals along the first direction.

[0082] Thus, the configuration of multiple resonant adjustment units provides the antenna with more possibilities for current path adjustment. The third resonant adjustment unit 235, the fourth resonant adjustment unit 236, and the fifth resonant adjustment unit 237 can excite or adjust the antenna's resonant mode at different frequency bands, enabling the antenna to cover a wider frequency range and achieve more precise resonant control at each frequency band. This is crucial for devices supporting multiple communication standards, ensuring that the antenna operates stably and efficiently at different frequency bands, thereby improving the device's communication capabilities and compatibility.

[0083] Furthermore, the complex resonant tuning section structure provides greater freedom in antenna design. Operators can flexibly adjust the parameters of each resonant tuning section, such as length, width, and bending angle, according to specific application scenarios and performance requirements. This allows the antenna to better adapt to the space constraints and functional needs of different devices, enabling personalized designs and meeting diverse market demands.

[0084] In some embodiments, reference is made to Figure 1 As shown, the third resonance adjustment unit 235, the fourth resonance adjustment unit 236 and the fifth resonance adjustment unit 237 all extend along the third direction Z and are arranged at intervals along the first direction X; the third direction Z intersects with the first direction X and the second direction Y respectively.

[0085] Along the first direction X, the distance between the fourth resonant adjustment unit 236 and the third resonant adjustment unit 235 is greater than the distance between the fourth resonant adjustment unit 236 and the fifth resonant adjustment unit 237.

[0086] It should be noted that different spacing will cause each resonant adjustment part to produce different degrees of resonance adjustment effect in different frequency bands, thereby enabling the antenna to cover multiple frequency bands more precisely.

[0087] For example, a larger spacing (between the fourth resonant adjustment unit 236 and the third resonant adjustment unit 235) may mainly affect the resonance of the lower frequency band, while a smaller spacing (between the fourth resonant adjustment unit 236 and the fifth resonant adjustment unit 237) may have a more significant effect on the resonance of the higher frequency band, thereby achieving differentiated adjustment of different frequency bands and improving the multi-band performance of the antenna.

[0088] At the same time, this differentiated spacing provides more dimensions for parameter adjustment in antenna design. The spacing, length, width and other parameters of the three resonant adjustment parts can be flexibly adjusted according to specific application requirements and performance indicators to achieve precise control of antenna performance.

[0089] In some embodiments, the second radiating arm 250 and the first radiating arm 240 can be a single unit, which helps to reduce the number of antenna devices, simplify the overall structure of the antenna, and reduce the difficulty of structural design.

[0090] For example, the second radiating arm 250 and the first radiating arm 240 can be L-shaped, wherein the L-shaped integrated design can realize complex antenna functions within a limited space. With the trend of miniaturization and integration in modern electronic devices, the L-shaped structure can more flexibly adapt to the internal spatial layout of the device, facilitating integration with other circuit components. This embodiment does not limit the shape of the antenna device.

[0091] In some embodiments, the first resonance adjustment part 231 can be a first groove formed on the antenna radiator 230; the second resonance adjustment part 232 can be a second groove formed on the antenna radiator 230.

[0092] The introduction of the grooves can excite multiple resonant modes on the antenna radiator 230. Different resonant modes correspond to different frequency ranges, and the superposition of these resonant modes can broaden the antenna's operating bandwidth. The first and second grooves can resonate independently or interact with each other, enabling the antenna to effectively radiate and receive signals over a wider frequency range, thus improving the antenna's adaptability to different communication standards and application scenarios.

[0093] For example, the width of the first resonant adjustment part 231 can be between 0.7-0.9 mm, and the width of the second resonant adjustment part 232 can be between 0.8-1 mm.

[0094] For example, the width of the first resonant adjustment part 231 can be set to 0.7mm, 0.8mm, 0.9mm, or any value between 0.7mm and 0.9mm, depending on actual needs. The width of the second resonant adjustment part 232 can be set to 0.8mm, 0.9mm, 1.0mm, or any value between 0.8mm and 1mm, depending on actual needs.

[0095] This ensures that the first resonant adjustment unit 231 and the second resonant adjustment unit 232 are within a suitable width range, which helps to accurately adjust the resonant frequency of the antenna in different frequency bands and meet the needs of multi-band communication.

[0096] For example, the width of the third resonant adjustment section 235 can be between 0.7 and 0.9 mm, the width of the fourth resonant adjustment section 236 can be between 0.9 and 1.1 mm, and the width of the fifth resonant adjustment section 237 can be between 1.2 and 1.4 mm. Appropriate widths can excite multiple resonant modes, and the widths of each resonant adjustment section can cooperate within their respective ranges to broaden the antenna's operating bandwidth. This allows the antenna to enhance radiation intensity in a specific direction or achieve more uniform omnidirectional radiation, reducing signal dead zones.

[0097] In some embodiments, the length of the first resonant adjustment section 231 can be between 0.55 and 0.6. For example, in this embodiment, the length of the first resonant adjustment section 231 is 0.57. This embodiment does not limit the description to this value.

[0098] In some embodiments, reference is made to Figure 3 As shown, the antenna device can be provided with a fixed pad 300, and the antenna radiating element 200 is connected to the substrate 100 through the fixed pad 300, thereby improving the connection strength and structural stability between the antenna radiating element 200 and the substrate 100.

[0099] The antenna device and electronic device provided in this application include a first resonant adjustment unit and a second resonant adjustment unit to divide the antenna radiating element into a plurality of first radiating arms arranged at intervals along a second direction. In this way, the arrangement of the plurality of first radiating arms can form a radiating array, capable of generating resonance at multiple different frequencies. These resonant frequencies mutually increase each other, enabling the antenna to achieve effective electromagnetic radiation and reception over a wider frequency range, thereby broadening the antenna's operating frequency band and generating a relatively wide bandwidth, maximizing the performance of the 700MHz-2700MHz 4G full-band.

[0100] The technical features of the above embodiments can be combined in any way.
