Description

Technical Field

[0001] Embodiments of this application relate to the technical field of antennas, and more particularly to an antenna, antenna assembly, and electronic device. Background Technology

[0002] In the antenna design process, the antenna's adjustability is usually poor, requiring the redesign of the circuit board connected to the antenna to change its directivity, which is time-consuming and labor-intensive, affecting the antenna design efficiency. Utility Model Content

[0003] Embodiments of this application provide an antenna, antenna assembly, and electronic device that can improve the tunability of the antenna and facilitate the improvement of antenna design efficiency.

[0004] On one hand, embodiments of this application provide an antenna. The antenna includes a radiator, a feed point, and a feed location. The radiator is used to radiate signals. The feed point and the feed location are spaced apart and connected to the radiator, respectively. An isolation slot and a guide slot are formed on the antenna, which penetrate the antenna along its thickness direction. The isolation slot is located between the feed point and the feed location, and the guide slot is connected to the isolation slot and surrounds a portion of the feed point or the feed location.

[0005] In some possible implementations, the feed point and the feed location are spaced apart along a first direction. When the guide channel surrounds a portion of the feed point, the guide channel includes a first sub-channel and a second sub-channel. The first sub-channel is located along the first direction on the side of the feed point away from the isolation channel, and the second sub-channel is located along a second direction on one side of the feed point, connecting the first sub-channel and the isolation channel. When the guide channel surrounds a portion of the feed location, the guide channel includes a third sub-channel and a fourth sub-channel. The third sub-channel is located along the first direction on the side of the feed location away from the isolation channel, and the fourth sub-channel is located along the second direction on one side of the feed location, connecting the third sub-channel and the isolation channel. The second direction is perpendicular to the first direction.

[0006] In some possible implementations, at least a portion of the radiator is located on one side of the feed point and the feed location along a second direction. With the guide slot surrounding a portion of the feed point, the second sub-slot is located on the side of the feed point away from the radiator along the second direction.

[0007] In some possible implementations, the feed point and the radiator are connected, and the feed point and the radiator are spaced apart. The antenna also includes a first connection structure comprising a first portion and a second portion, the first portion extending along a second direction, and the second portion extending along the first direction. The first portion is located along the first direction on the side of the feed point away from the feed point and is connected to the radiator. The second portion is located along the second direction on the side of the feed point away from the radiator and is connected to the feed point. The first portion and the feed point are spaced apart to form a first sub-slot, and the second portion and the feed point are spaced apart to form a second sub-slot.

[0008] In some possible implementations, at least a portion of the radiator is located on one side of the feed point and feed location along the second direction. With the guide slot surrounding a portion of the feed location, the fourth sub-slot is located on the side of the feed location away from the radiator along the second direction.

[0009] In some possible implementations, the feed point and the radiator are connected, and the feed point and the radiator are spaced apart. The antenna also includes a second connection structure comprising a connected third portion and a fourth portion, the third portion extending along a second direction and the fourth portion extending along a first direction. The third portion is located along the first direction on the side of the feed point away from the feed point and is connected to the radiator, while the fourth portion is located along the second direction on the side of the feed point away from the radiator and is connected to the feed point. The third portion and the feed point are spaced apart to form a third sub-slot. The fourth portion and the feed point are spaced apart to form a fourth sub-slot.

[0010] In some possible implementations, the radiator includes a first radiator, a second radiator, and a third radiator. The first radiator, the second radiator, and the third radiator are used to radiate signals in different frequency bands.

[0011] In some possible implementations, the first radiator includes a first sub-radiator and a second sub-radiator, with at least a portion of the first sub-radiator located on one side of the feed point and feed location along a first direction, and at least a portion of the second sub-radiator located on the other side of the feed point and feed location along the first direction.

[0012] On the other hand, embodiments of this application provide an antenna assembly. The antenna assembly includes a circuit board and an antenna as described above. The circuit board includes a first connection point and a second connection point spaced apart. The first connection point is connected to a feed point, and the second connection point is connected to a feed point.

[0013] In another aspect, embodiments of this application provide an electronic device that includes the antenna assembly described above.

[0014] In summary, the embodiments of this application have at least the following beneficial effects:

[0015] In the embodiments of this application, compared to setting the guide groove to extend in a direction away from the feed point and feed location, setting the guide groove around a part of the feed point or feed location can change the directivity of the antenna without changing the attributes of the feed point and feed location, meeting the requirements of field testing and over-the-air (OTA) testing, without redesigning the circuit board, improving the antenna's adjustability, saving time and effort, and thus improving the antenna's design efficiency.

[0016] Understandably, the antenna's directivity differs when the guide slot extends around the feed point versus when it extends around the feed point. This allows the guide slot to be positioned to extend around or around the feed point, improving the antenna's adjustability. Attached Figure Description

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] Figure 1 These are schematic diagrams illustrating the structure of electronic devices provided in some embodiments of this application. For example... Figure 1 As shown, an embodiment of this application provides an electronic device 300. For example, the electronic device 300 can be an electronic device with communication functions, such as a mobile phone, laptop computer, tablet computer, smartwatch, smart bracelet, etc. Alternatively, the electronic device 300 can also be other devices besides those described above. The embodiments of this application do not further limit the specific form of the electronic device 300.

[0037] Taking a mobile phone as an example, the electronic device 300 may include a housing 310 and a display panel 320. The display panel 320 is used to display image information, and the display panel 320 and the housing 310 are connected.

[0038] In some examples, the electronic device 300 also includes an antenna assembly 200. Figure 1 Not shown in the image, see [link / reference]. Figure 2 The antenna assembly 200 can be placed within the accommodating space enclosed by the housing 310, so that the housing 310 can protect the antenna assembly 200.

[0039] For example, antenna assembly 200 can be an inverted-F antenna (IFA). Alternatively, antenna assembly 200 can also be other types of antennas, which are not further limited in the embodiments of this application.

[0040] Figure 2 This is a schematic diagram of the structure of an antenna assembly provided in some embodiments of this application. In some examples, such as... Figure 2 As shown, the antenna assembly 200 includes an antenna 100 and a circuit board 210. The antenna 100 includes a feed point 101 and a feed point 102 spaced apart. For example, the feed point 101 and the feed point 102 may be spaced apart along a first direction X.

[0041] Antenna 100 may include a thin metal sheet, such as a copper sheet. Alternatively, antenna 100 may also include other metals or alloys besides copper. The embodiments of this application do not further limit the material of antenna 100. Feed point 101 and feed point 102 may be pads, with feed point 101 used to connect to the power supply terminal and feed point 102 used to connect to the ground terminal.

[0042] The circuit board 210 may include at least one of a printed circuit board (PCB) and a flexible printed circuit (FPC). The embodiments of this application do not further limit the specific form of the circuit board 210.

[0043] The circuit board 210 includes a first connection point and a second connection point (not shown in the figure) spaced apart. The first connection point is connected to the power supply point 101, and the second connection point is connected to the power supply point 102.

[0044] For example, the first connection point and the second connection point can be set at intervals along the first direction X, and the distance between the first connection point and the second connection point along the first direction X is equal to or approximately equal to the distance between the feed point 101 and the feed point 102 along the first direction X, so that the first connection point can be connected to the feed point 101 and the second connection point can be connected to the feed point 102.

[0045] Figure 3 for Figure 2 A partially enlarged schematic diagram of region H1. It can be understood that the first connection point is the power supply connection point, and the second connection point is the grounding connection point. The first and second connection points are connected to feed point 101 and feed point 102 respectively, as shown below. Figure 3 As indicated by the middle arrow G1, current can flow along the direction from feed point 101 to feed point 102, and the circuit board 210 can supply power to the antenna 100, thereby enabling the antenna 100 to radiate signals outward.

[0046] For example, such as Figure 2 As shown, a positioning through-hole Q may be provided on the antenna 100, and the positioning through-hole Q penetrates the antenna 100 along the thickness direction of the antenna 100. The positioning through-hole Q can play a positioning role and improve the ease of assembly between the antenna 100 and other components (such as the circuit board 210).

[0047] Continue to refer to Figure 2 In some examples, antenna 100 includes a radiator 110 for radiating signals, and feed point 101 and feed point 102 are respectively connected to the radiator 110. At least a portion of the radiator 110 is located on one side of feed point 101 and feed point 102 along a second direction Y.

[0048] For example, feed point 101, feed point 102 and radiator 110 can be a single-piece structure to improve the reliability of the connection between the three.

[0049] The feed point 101 and the radiator 110 can be directly connected or indirectly connected through other components (such as the first connection structure 103). The feed point 102 and the radiator 110 can be directly connected or indirectly connected through other components (such as the second connection structure 104).

[0050] Understandably, the current can flow along the direction from the feed point 101, the radiator 110 to the feed point 102, so that the radiator 110 can radiate signals to the outside world, such as electromagnetic wave signals, so that the electronic device 300 can achieve communication.

[0051] The second direction Y is perpendicular to the first direction X. Understandably, the second direction Y and the first direction X can be perpendicular or approximately perpendicular, that is, the angle between the second direction Y and the first direction X can be 90° (unit: degrees), or it can be 88° or 89°, etc.

[0052] In some examples, there are multiple radiators 110, which can be spaced out and connected to feed point 101 and feed point 102 respectively. Different radiators 110 can be used to radiate signals of different frequency bands.

[0053] For example, such as Figure 2 As shown, the radiator 110 includes a first radiator 111, a second radiator 112, and a third radiator 113, which are used to radiate signals of different frequency bands. In this way, the antenna 100 can radiate signals of different frequency bands, improving the applicability of the antenna 100.

[0054] The first radiator 111 can be used to radiate 5G wireless fidelity (WIFI) signals, the second radiator 112 can be used to radiate global positioning system (GPS) signals, and the third radiator 113 can be used to radiate 2.4G WIFI signals. Alternatively, the first radiator 111, the second radiator 112, and the third radiator 113 can also be used to radiate other signals, and the embodiments of this application do not further limit this.

[0055] In some examples, such as Figure 2 As shown, the first radiator 111 may include a first sub-radiator 111a and a second sub-radiator 111b. At least a portion of the first sub-radiator 111a is located on one side of the feed point 101 and the feed point 102 along the first direction X, and at least a portion of the second sub-radiator 111b is located on the other side of the feed point 101 and the feed point 102 along the first direction X.

[0056] The first radiator 111 is configured to include a first sub-radiator 111a and a second sub-radiator 111b, so that the first radiator 111 can support dual frequency bands and realize multiple inputs and multiple outputs.

[0057] Alternatively, the first radiator 111 may not include the first sub-radiator 111a and the second sub-radiator 111b (see [link]). Figure 8 At this time, at least a portion of the first radiator 111 can be located on one side of the feed point 101 and the feed point 102 along the first direction X.

[0058] At least a portion of the second radiator 112 and at least a portion of the third radiator 113 may be located on the same side of the feed point 101 and the feed point 102 along the first direction X.

[0059] For example, such as Figure 2 As shown, when the first radiator 111 includes a first sub-radiator 111a and a second sub-radiator 111b, a portion of the second sub-radiator 111b, a portion of the second radiator 112 and a portion of the third radiator 113 can be located on the same side of the feed point 101 and the feed point 102 along the first direction X, and a portion of the first sub-radiator 111a can be located on the other side of the feed point 101 and the feed point 102 along the first direction X.

[0060] Understandably, the first radiator 111, the second radiator 112, and the third radiator 113 can also be arranged in other ways than those described above. The embodiments of this application do not further limit the arrangement and shape of the first radiator 111, the second radiator 112, and the third radiator 113.

[0061] Continue to refer to Figure 2 In some examples, the antenna 100 has an isolation slot M and a guide slot P, which penetrate the antenna 100 along its thickness direction. The isolation slot M is located between the feed point 101 and the feed point 102. The guide slot P and the isolation slot M are connected.

[0062] For example, the isolation slot M can extend along the second direction Y and is located between feed point 101 and feed point 102. The isolation slot M can isolate feed point 101 and feed point 102, reducing the risk of short circuit between feed point 101 and feed point 102.

[0063] The guide slot P and the isolation slot M can be integrally formed, allowing the guide slot P to communicate with the isolation slot M. Understandably, the guide slot P can guide the direction of current. The direction of the current in the antenna 100 differs depending on the extension direction of the guide slot P.

[0064] Taking mobile phones as an example, mobile phones have evolved from 2G (second-generation mobile technology), 3G (third-generation mobile technology), and 4G (fourth-generation mobile technology) to 5G (fifth-generation mobile technology) and even the future 6G (sixth-generation mobile technology). The antenna environment is becoming increasingly worse, and the number of antennas is increasing, further exacerbating the already challenging environment for each functional antenna. The space for antenna placement is shrinking, limiting the area of ​​the antenna pattern and resulting in increasingly poor antenna adjustability.

[0065] Currently, antennas are compactly designed, with most using a single feed and single ground configuration. This significantly increases the difficulty of antenna tuning, causing the antenna's directivity to fail to meet field measurement requirements. In weak field environments, this can lead to a series of problems such as signal disconnection.

[0066] In some implementations, such as Figure 2 As shown, the guide slot P typically extends away from the feed point 101 and the feed point 102; that is, the guide slot P typically does not surround the feed point 101 or the feed point 102.

[0067] exist Figure 2 In this design, if the antenna performance cannot be adjusted, it is usually necessary to swap the attributes of the feed point and the feed location for debugging. That is, the original feed point is used as the feed location, and the original feed location is used as the feed point.

[0068] Feed point 101 and feed point 102 are connected to circuit board 210 respectively. Usually, circuit board 210 needs to be redesigned to swap the attributes of feed point 101 and feed point 102, which is time-consuming and labor-intensive and affects the design efficiency of the antenna.

[0069] Figure 4 This is a schematic diagram of the structure of an antenna assembly provided in some other embodiments of this application. Figure 5 for Figure 4 A magnified view of a portion of region H2. Figure 6 This is a schematic diagram of the structure of an antenna assembly provided in some embodiments of this application. Figure 7 for Figure 6 A magnified view of a portion of region H3. Figure 8 This is a schematic diagram of the structure of an antenna assembly provided in some embodiments of this application. Figure 9 for Figure 8 A magnified view of a portion of region H4. Figure 10 This is a schematic diagram of the structure of an antenna assembly provided in some embodiments of this application. Figure 11 for Figure 10 A magnified view of a portion of the H5 area.

[0070] Based on this, in embodiments of this application, the guide groove P surrounds a portion of the feed point 101 or feed point 102. That is, as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the guide slot P can extend around the feed point 101, or, as... Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the guide groove P can also extend around the feed point 102.

[0071] Understandably, the antenna 100 operates by converting between electric and magnetic fields. By changing the extension direction of the guide slot P, the direction of the current in the antenna 100 can be changed, and the direction of the coupling current formed in the guide slot P can also be changed, thereby changing the directivity of the antenna 100.

[0072] As the guide slot P extends away from the feed point 101 and the feed point 102, the current direction of the antenna 100 is as follows: Figure 3 As indicated by the middle arrow G1, the current direction of the antenna 100 is as follows when the guide slot P extends around the feed point 101. Figure 5 The direction of the middle arrow G2 and Figure 7 As indicated by the middle arrow G3, the current direction of the antenna 100 is as follows when the guide slot P extends around the feed point 102. Figure 9 The direction of the middle arrow G4 and Figure 11 As indicated by the middle arrow G5.

[0073] In other words, the directivity of the antenna 100 when the guide slot P extends away from the feed point 101 and the feed point 102 is different from the directivity of the antenna 100 when the guide slot P surrounds a part of the feed point 101 or the feed point 102.

[0074] Understandably, in the accompanying drawings of this application, the following characters are used... Figure 3 , Figure 5 , Figure 7 , Figure 9 and Figure 11 For example, to simplify the structure of the attached diagram, only the direction of current flow between feed point 101 and feed point 102 is shown, without showing the path of current flowing from feed point 101 to radiator 110 and then through radiator 110 to feed point 102.

[0075] Compared to setting the guide slot P to extend away from the feed point 101 and feed location 102, setting the guide slot P around a part of the feed point 101 or feed location 102 can change the directivity of the antenna 100 without changing the properties of the feed point 101 and feed location 102, meeting the requirements of field testing and over-the-air (OTA) testing, without the need to redesign the circuit board 210, improving the adjustability of the antenna 100, saving time and effort, and thus improving the design efficiency of the antenna 100.

[0076] Understandably, the directivity of antenna 100 is different when the guide slot P extends around feed point 101 and when the guide slot P extends around feed point 102. In this way, the guide slot P can be set to extend around feed point 101 or feed point 102 as needed, improving the adjustability of antenna 100.

[0077] Understandably, the directivity of the antenna 100 can also be changed by altering the width and length of the isolation slot M and the guide slot P. The embodiments of this application do not further limit the values ​​of the width and length of the isolation slot M and the guide slot P.

[0078] In some examples, such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, when the guide slot P surrounds a portion of the feed point 101, the guide slot P includes a first sub-slot P1 and a second sub-slot P2. The first sub-slot P1 is located on the side of the feed point 101 away from the isolation slot M along the first direction X, and the second sub-slot P2 is located on the side of the feed point 101 along the second direction Y, and connects the first sub-slot P1 and the isolation slot M.

[0079] For example, the first sub-slot P1 and the second sub-slot P2 can be an integrally formed structure. The first sub-slot P1 can extend along the second direction Y and is located along the first direction X on the side of the feed point 101 away from the isolation slot M. The second sub-slot P2 can extend along the first direction X and is located along the second direction Y on one side of the feed point 101, and connects the first sub-slot P1 and the isolation slot M, so that the guide slot P can surround a portion of the feed point 101.

[0080] Understandably, for feed point 101, the unenclosed portions of the first sub-slot P1 and the second sub-slot P2 can be used to connect with the radiator 110.

[0081] In some examples, such as Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, when the guide groove P surrounds a portion of the feed point 102, the guide groove P includes a third sub-groove P3 and a fourth sub-groove P4. The third sub-groove P3 is located on the side of the feed point 102 away from the isolation groove M along the first direction X, and the fourth sub-groove P4 is located on the side of the feed point 102 along the second direction Y, and connects the third sub-groove P3 and the isolation groove M.

[0082] For example, the third sub-slot P3 and the fourth sub-slot P4 can be a single-piece structure. The third sub-slot P3 can extend along the second direction Y and is located along the first direction X on the side of the feed point 102 away from the isolation slot M. The fourth sub-slot P4 can extend along the first direction X and is located along the second direction Y on one side of the feed point 102, and connects the third sub-slot P3 and the isolation slot M, so that the guide slot P can surround a portion of the feed point 102.

[0083] Understandably, for feed point 102, the unenclosed portions of the third sub-slot P3 and the fourth sub-slot P4 can be used to connect with the radiator 110.

[0084] In some examples, such as Figure 4 As shown, when the guide slot P surrounds a portion of the feed point 101, the second sub-slot P2 is located on the side of the feed point 101 away from the radiator 110 along the second direction Y.

[0085] This configuration reduces the impact of the second sub-slot P2 on the connection between the feed point 101 and the radiator 110, allowing the feed point 101 to be directly connected to the radiator 110 along the second direction Y, which helps reduce the loss of the antenna 100 and improve its efficiency.

[0086] Continue to refer to Figure 4 In some examples, feed point 101 and radiator 110 are connected, and feed point 102 and radiator 110 are spaced apart.

[0087] Understandably, the second sub-slot P2 is located on the side of the feed point 101 away from the radiator 110, so that the feed point 101 can be directly connected to the radiator 110. For example, the feed point 102 can be spaced apart from the first radiator 111, the second radiator 112, and the third radiator 113, respectively.

[0088] The antenna 100 also includes a first connection structure 103, which includes a first portion 1031 and a second portion 1032 that are connected. The first portion 1031 extends along a second direction Y, and the second portion 1032 extends along a first direction X. For example, the first portion 1031 and the second portion 1032 can be an integrally formed structure to improve the connection reliability between them.

[0089] The first portion 1031 is located along the first direction X on the side of the feed point 101 away from the feed point 102 and is connected to the radiator 110. The second portion 1032 is located along the second direction Y on the side of the feed point 101 away from the radiator 110 and is connected to the feed point 102. The first portion 1031 and the feed point 101 are spaced apart to form a first sub-slot P1, and the second portion 1032 and the feed point 101 are spaced apart to form a second sub-slot P2.

[0090] This configuration allows the guide slot P to surround a portion of the feed point 101. Understandably, current can flow along the first connection structure 103 around the feed point 101. Compared to setting the guide slot P to extend away from the feed point 101 and feed point 102, this configuration allows the directivity of the antenna 100 to be changed without altering the properties of the feed point 101 and feed point 102, improving the adjustability of the antenna 100 and thus increasing its design efficiency.

[0091] In some examples, such as Figure 8 As shown, when the guide slot P surrounds a portion of the feed point 102, the fourth sub-slot P4 is located on the side of the feed point 102 away from the radiator 110 along the second direction Y.

[0092] This configuration reduces the impact of the fourth sub-slot P4 on the connection between the feed point 102 and the radiator 110, allowing the feed point 102 to be directly connected to the radiator 110 along the second direction Y.

[0093] In some examples, such as Figure 8 As shown, feed point 102 is connected to radiator 110, and feed point 101 and radiator 110 are spaced apart.

[0094] Understandably, the fourth sub-slot P4 is located on the side of feed point 102 away from radiator 110, so that feed point 102 can be directly connected to radiator 110.

[0095] The antenna 100 also includes a second connection structure 104, which includes a third portion 1041 and a fourth portion 1042 connected together. The third portion 1041 extends along a second direction Y, and the fourth portion 1042 extends along a first direction X. For example, the third portion 1041 and the fourth portion 1042 can be an integrally formed structure to improve the connection reliability between them.

[0096] The third portion 1041 is located along the first direction X on the side of the feed point 102 away from the feed point 101 and is connected to the radiator 110. The fourth portion 1042 is located along the second direction Y on the side of the feed point 102 away from the radiator 110 and is connected to the feed point 101. The third portion 1041 and the feed point 102 are spaced apart to form a third sub-slot P3. The fourth portion 1042 and the feed point 102 are spaced apart to form a fourth sub-slot P4.

[0097] This configuration allows the guide slot P to surround a portion of the feed point 102. Understandably, current can flow along the second connection structure 104 around the feed point 102. Compared to having the guide slot P extend away from the feed points 101 and 102, this configuration allows the directivity of the antenna 100 to be changed without altering the properties of the feed points 101 and 102, improving the adjustability of the antenna 100 and thus increasing its design efficiency.
