Description

Technical Field

[0001] This invention relates to the field of communication technology, and more particularly to an antenna unit and an electronic device having said antenna unit. Background Technology

[0002] Currently, with the popularization of 5G communication technology, people's communication experience is getting better and better. However, the number of antennas is also increasing, and with the popularization of full-screen and curved screens, the clearance space left for antennas is getting smaller and smaller. In particular, as electronic devices have more and more functions, the number of internal functional components is also increasing, which also squeezes the antenna space. For example, when a functional component is close to an antenna, the proximity of the two can prevent the antenna from having a feeding structure and / or grounding structure, making it difficult to set up the antenna in that area and exacerbating the shortage of antenna installation space. Summary of the Invention

[0003] This application provides an antenna assembly and an electronic device to solve the above-mentioned problems.

[0004] In a first aspect, an electronic device is provided, comprising a functional device and a first antenna unit. The first antenna unit includes a first radiating stub, at least one parasitic stub, and a first feed source. The first radiating stub and the at least one parasitic stub are spaced apart and coupled. The first radiating stub includes a first feed point connected to the first feed source. Under the excitation of the first feed source, the first radiating stub supports the transmission and reception of electromagnetic wave signals in a first frequency band, and the first radiating stub, in cooperation with the at least one parasitic stub, supports the transmission and reception of electromagnetic wave signals in a second frequency band. The functional device is located close to and spaced apart from the first radiating stub of the first antenna unit, and at least the projection of the side of the functional device closest to the first radiating stub onto the first radiating stub is located within a target area outside the first feed point of the first radiating stub.

[0005] Secondly, an antenna assembly is also provided, the antenna element including a first radiating stub, at least one parasitic stub, and a first feed source. The first radiating stub and the at least one parasitic stub are spaced apart and coupled. The first radiating stub includes a first feed point connected to the first feed source. Under the excitation of the first feed source, the first radiating stub supports the transmission and reception of electromagnetic wave signals in a first frequency band, and the first radiating stub, in cooperation with the at least one parasitic stub, supports the transmission and reception of electromagnetic wave signals in a second frequency band.

[0006] The electronic device and antenna assembly of this application, when the functional device is close to the first radiating stub of the first antenna element, ensure that the projection of the side of the functional device near the first radiating stub onto the first radiating stub is located within a target area outside the first feed point of the first radiating stub. That is, the area directly opposite the first radiating stub and the side of the functional device near the first radiating stub does not include connection points such as the first feed point; it only includes the first radiating stub itself. Since the first feed point is located outside the target area, the proximity of the functional device to the first radiating stub does not affect the feed connection of the first feed point. Therefore, the electronic device of this application can place the first antenna element close to the functional device, making full use of space. Furthermore, since the first antenna element / antenna element supports at least two frequency bands, it can effectively meet the requirements of multiple frequency bands within a limited space.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] In the description of the embodiments of this invention, it should be understood that the terms "upper," "lower," "thickness," "width," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not imply or indicate 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 the invention. The term "connection" in this application, unless otherwise specified, mainly refers to a physical structural connection, and may also include electrical connection, direct connection, or indirect connection, etc., where specified. In the description of the embodiments of this invention, the terms "first," "second," etc., are not specific, but are used to distinguish objects with the same name. Where specified in the specification, the objects with the same name referred to by the terms "first," "second," etc., may be the same objects. In this application, the term "A and / or B" includes multiple cases such as "A," "B," and "A and B." The term "connection" in this application includes meanings such as "electrical connection," "direct connection," and / or "indirect connection."

[0029] Please see Figure 1 This is a schematic plan view illustrating a portion of the internal structure of an electronic device 100 in some embodiments of this application. For example... Figure 1As shown, the electronic device 100 includes a functional device 1 and a first antenna unit 2. The first antenna unit 2 includes a first radiating stub 21, at least one parasitic stub 22, and a first feed 23. The first radiating stub 21 and the at least one parasitic stub 22 are spaced apart and coupled. The first radiating stub 21 includes a first feed point F1 connected to the first feed 23. Under the excitation of the first feed 23, the first radiating stub 21 supports the transmission and reception of electromagnetic wave signals in a first frequency band. The first radiating stub 21 and the at least one parasitic stub 22 cooperate to support the transmission and reception of electromagnetic wave signals in a second frequency band. The functional device 1 is close to and spaced apart from the first radiating stub 21 and / or at least one parasitic stub 22 of the first antenna unit 2. At least the projection of the edge of the functional device 1 closest to the first radiating stub 21 onto the first radiating stub 21 is located in a target area outside the first feed point F1 of the first radiating stub 21.

[0030] Therefore, in this application, when the functional device 1 is close to the first radiating branch 21 of the first antenna element 2, since the projection of the edge of the functional device 1 near the first radiating branch 21 onto the first radiating branch 21 is located in the target area outside the first feed point F1 of the first radiating branch 21, that is, the area directly opposite the first radiating branch 21 and the edge of the functional device 1 near the first radiating branch 21 does not include the connection point such as the first feed point F1, that is, it only includes the first radiating branch 21 itself, and the first feed point F1 is located outside the target area, even if the functional device 1 is close to the first radiating branch 21, it does not affect the feed connection of the first feed point F1. Therefore, the electronic device 100 of this application can set the first antenna element 2 near the functional device 1, which can make full use of space, and since the first antenna element 2 supports at least two frequency bands, it can effectively meet the needs of multiple frequency bands in a limited space.

[0031] In this application, the target area outside the first feed point F1 of the first radiating branch 21, as mentioned above, may refer to the area of ​​the first radiating branch 21 that does not include connection points such as feed points, but only includes the structure of the branch 21 itself.

[0032] In this application, the functional device being close to and spaced apart from the first radiating branch of the first antenna unit can mean that the functional device 1 is at least close to and spaced apart from the first radiating branch 21 of the first antenna unit 2. That is, the functional device 1 may be close to and spaced apart only from the first radiating branch 21 of the first antenna unit 2, or it may also be partially close to and spaced apart from at least one parasitic branch 22. Thus, the side of the functional device 1 that is close to the first radiating branch 21 may be directly opposite the first radiating branch 21, or it may also be partially opposite the at least one parasitic branch 22 or the gap between the first radiating branch 21 and the at least one parasitic branch 22. In this application, the projection of the side of the functional device near the first radiating stub onto the first radiating stub is located in the target area outside the first feed point of the first radiating stub. This can also refer to the following: when the functional device 1 is only close to and spaced apart from the first radiating stub 21 of the first antenna unit 2, the projection of the side of the functional device 1 near the first radiating stub 21 on one side of the first radiating stub 21 is located in the target area outside the first feed point F1 of the first radiating stub 21. Alternatively, when the side of the functional device 1 near the first radiating stub 21 is also partially aligned with the at least one parasitic stub 22 or the gap between the first radiating stub 21 and the at least one parasitic stub 22, the projection of the side of the functional device 1 near the first radiating stub 21 on the side where the first radiating stub 21 is located is also partially located outside the first radiating stub 21. That is, a portion of the projection is located on at least one parasitic stub 22 or the gap between the first radiating stub 21 and the at least one parasitic stub 22, and specifically on the area of ​​the parasitic stub 22 without a grounding structure, etc.

[0033] Furthermore, the projection of the side of the functional device 1 near the first radiating branch 21 onto the first radiating branch 21 refers to the portion of the projection of the side of the functional device 1 near the first radiating branch 21 onto the side of the first radiating branch 21. Specifically, the projection of the side of the functional device 1 near the first radiating branch 21 onto the side of the first radiating branch 21 can be entirely located on the first radiating branch 21, or a portion of the projection can be located outside the first radiating branch 21, for example, in the gap between the first radiating branch 21 and the parasitic branch 22, or in the area of ​​the parasitic branch 22 excluding the grounding structure.

[0034] In some embodiments, such as Figure 1As shown, the first radiating branch 21 includes a first end 21a and a second end 21b, both of which are open circuits. The first feed point F1 is located between the first end 21a and the second end 21b, and divides the first radiating branch 21 into a first branch portion 211 located between the first feed point F1 and the first end 21a and a second branch portion 212 located between the first feed point F1 and the second end 21b. The length of the first branch portion 211 is greater than the length of the second branch portion 212, and the target area is located within the first branch portion 211.

[0035] That is, in some embodiments, both ends of the first radiating stub 21 are open circuits. Therefore, the first radiating stub 21 has only one connection point, the first feed point F1, and does not include grounding points or other connection points. Since the first feed point F1 is close to the second end 21b of the first radiating stub 21, a longer stub portion, namely the first stub portion 211, can be left on the first radiating stub 21. Thus, the longer first stub portion 211 is set at the position corresponding to the functional device 1, which allows a larger functional device to be set close together. Since there is no need for feed and grounding in this target area, there is no need to set up a feed structure for feed and a grounding structure for grounding in this target area. Therefore, the functional device 1 can be set very close to meet the internal layout requirements of the electronic device 100, and an antenna stub can still be set at this position to achieve the corresponding frequency band without wasting space.

[0036] The power supply structure can be a power supply spring, a power supply wire, or the like, and the grounding structure can be a grounding spring, a grounding wire, or the like.

[0037] In some embodiments, both ends of the first radiating stub 21 are open circuits, equivalent to a monopole antenna. The first radiating stub 21 can operate in a radiation mode, specifically a half-wavelength resonant mode. That is, the electrical length of the first radiating stub 21 is λ1 / 2, where λ1 is the wavelength corresponding to the first frequency band, and it can resonate in the first frequency band through a half-wavelength resonant mode, thus supporting the transmission and reception of electromagnetic wave signals in the first frequency band.

[0038] In this application, the wavelength corresponding to a certain frequency band may specifically refer to the wavelength corresponding to the center frequency of the frequency band. The resonance of a certain segment or multiple segments in a certain frequency band may be the center frequency of the resonance in that frequency band.

[0039] Please see Figure 2 This is another planar schematic diagram of an electronic device in some embodiments of this application. In some embodiments, such as Figure 2As shown, the at least one parasitic branch 22 includes a first parasitic branch 221 and a second parasitic branch 222. The first radiating branch 21 is located between the first parasitic branch 221 and the second parasitic branch 222 and is spaced apart from and coupled to both the first parasitic branch 221 and the second parasitic branch 222. Under the excitation of the first feed source 23, the first radiating branch 21 and the first parasitic branch 221 cooperate to support the transmission and reception of electromagnetic wave signals in the second frequency band, and the first radiating branch 21 and the second parasitic branch 222 cooperate to support the transmission and reception of electromagnetic wave signals in the third frequency band.

[0040] That is, in some embodiments, the at least one parasitic branch 22 includes two parasitic branches, a first parasitic branch 221 and a second parasitic branch 222, with the first parasitic branch 221 and the second parasitic branch 222 located on both sides of the first radiating branch 21 and coupled to it. The first radiating branch 21 and the first parasitic branch 221 cooperate to support the transmission and reception of electromagnetic wave signals in the second frequency band, and the first radiating branch 21 and the second parasitic branch 222 cooperate to support the transmission and reception of electromagnetic wave signals in the third frequency band.

[0041] Therefore, in some embodiments, the first radiating branch 21, together with the first parasitic branch 221 and the second parasitic branch 222, can support the second and third frequency bands. Thus, the first antenna element 2 can support three frequency bands, thereby achieving coverage of more frequency bands and further meeting the current demand for multiple frequency bands.

[0042] In this application, as described above, the first end 21a and the second end 21b of the first radiating branch 21 are both open circuit ends. The first parasitic branch 221 includes a third end 221a and a fourth end 221b, where the third end 221a is an open circuit end and the fourth end 221b is a grounding end used for connection to ground (GND). The second parasitic branch 222 includes a fifth end 222a and a sixth end 222b, where the fifth end 222a is an open circuit end and the sixth end 222b is a grounding end used for connection to ground (GND). The first end 21a of the first radiating branch 21 and the third end 221a of the first parasitic branch 221 are positioned close to each other and spaced apart. The first radiating branch 21 is coupled to the first parasitic branch 221. The second end 21b of the first radiating branch 21 and the fifth end 222a of the second parasitic branch 222 are positioned close to and spaced apart from each other to couple with the second parasitic branch 222. As mentioned above, the first radiating branch 21 operates in radiation mode and supports the transmission and reception of electromagnetic wave signals in the first frequency band. The first branch portion 211 cooperates with the first parasitic branch 221 to operate in radiation mode and supports the transmission and reception of electromagnetic wave signals in the second frequency band. The second branch portion 212 cooperates with the second parasitic branch 222 to operate in radiation mode and supports the transmission and reception of electromagnetic wave signals in the third frequency band.

[0043] That is, in some embodiments, both the first parasitic branch 221 and the second parasitic branch 222 have an open-circuit structure at one end and a grounded structure at the other end. The open-circuit ends of the first parasitic branch 221 and the second parasitic branch 222 are respectively close to and spaced apart from the first end 21a and the second end 21b of the first radiating branch 21, thus having corresponding coupling gaps. This allows both the first parasitic branch 221 and the second parasitic branch 222 to be coupled to the first radiating branch 21 through corresponding coupling gaps. Specifically, the first radiating branch 21 and the first parasitic branch 221 cooperate to support the transmission and reception of electromagnetic wave signals in the second frequency band. Specifically, the first branch portion 211 located between the first feed point F1 and the first end 21a of the first radiating branch 21 cooperates with the first parasitic branch 221 to support the transmission and reception of electromagnetic wave signals in the second frequency band, and operates in radiation mode. The first radiating stub 21 and the second parasitic stub 222 cooperate to support the transmission and reception of electromagnetic wave signals in the third frequency band. Specifically, the second stub portion 212 located between the first feed point F1 and the second end 21b of the first radiating stub 21 cooperates with the second parasitic stub 222 to support the transmission and reception of electromagnetic wave signals in the third frequency band, and operates in radiation mode.

[0044] Therefore, in some embodiments, as described above, the first radiating stub 21 is open-circuited at both ends, serving as a monopole antenna, operating in radiation mode, specifically a half-wavelength resonant mode. The first stub portion 211 and the first parasitic stub 221 also cooperate in operating in radiation mode to support the transmission and reception of electromagnetic wave signals in the second frequency band, and the second stub portion 212 and the second parasitic stub 222 also cooperate in operating in radiation mode to support the transmission and reception of electromagnetic wave signals in the third frequency band.

[0045] Wherein, when the side of the functional device 1 near the first radiating branch 21 is also partially aligned with the at least one parasitic branch 22 or the gap between the first radiating branch 21 and the at least one parasitic branch 22, the side of the functional device 1 near the first radiating branch 21 may be partially aligned with the region of the first parasitic branch 221 excluding the fourth end 221b, and the projection of the side of the functional device 1 near the first radiating branch 21 onto the first parasitic branch 221 is located in the region of the first parasitic branch 221 excluding the fourth end 221b.

[0046] In this application, "A" and "B" are set close to each other and spaced apart, or "A" and "B" are adjacent to each other, which means that "A" and "B" are set apart and the distance between them is less than a preset distance, such as less than 0.8 cm or 1 cm.

[0047] In some embodiments, such as Figure 2 As shown, the second parasitic branch 222, the first radial branch 21, and the first parasitic branch 221 are all straight strips. The second parasitic branch 222, the first radial branch 21, and the first parasitic branch 221 are arranged sequentially along a preset direction, and the extension direction of the second parasitic branch 222, the first radial branch 21, and the first parasitic branch 221 is the same as the arrangement direction, that is, the same as the arrangement direction of the second parasitic branch 222, the first radial branch 21, and the first parasitic branch 221.

[0048] That is, in some embodiments, the second parasitic branch 222, the first radial branch 21 and the first parasitic branch 221 are all straight strips, and the second parasitic branch 222, the first radial branch 21 and the first parasitic branch 221 are spaced apart from each other and arranged in a straight line.

[0049] Wherein, the second parasitic branch 222, the first radial branch 21, and the first parasitic branch 221 can be the dimensions along the extension direction of the longest side of the second parasitic branch 222, the first radial branch 21, and the first parasitic branch 221. For example, when the second parasitic branch 222, the first radial branch 21, and the first parasitic branch 221 are straight strips, the extension direction of the longest side of the second parasitic branch 222, the first radial branch 21, and the first parasitic branch 221 is the extension direction of the longest straight side.

[0050] In some embodiments, at least one of the second parasitic branch 222, the first radial branch 21, and the first parasitic branch 221 may also be bent. For example, the first radial branch 21 may be bent, while the second parasitic branch 222 and the first parasitic branch 221 may be straight. The first radial branch 21 may include two portions connected at an angle, and the extending directions of the two portions connected at an angle may be the same as the extending directions of the second parasitic branch 222 and the first parasitic branch 221, respectively. In this case, the second parasitic branch 222, the first radial branch 21, and the first parasitic branch 221 may also form a generally "L"-shaped structure.

[0051] Please see Figure 3 This is a schematic diagram showing the current distribution of the first antenna element 2 of the electronic device 100 in some embodiments of this application operating in a first frequency band. Figure 3 It can be used as Figure 2 The schematic diagram of the current distribution of the first antenna unit 2 operating in the first frequency band is obtained by simulation test using the electronic device 100 shown as an example.

[0052] like Figure 3 As shown, when the first antenna element 2 operates in the first frequency band, since the first radiating stub 21 mainly supports the transmission and reception of electromagnetic wave signals in the first frequency band, the current i1 in the first frequency band is mainly distributed on the first radiating stub 21, and from... Figure 3 It can be seen that the direction of the current i1 is the same throughout the first radiating branch 21, for example, Figure 3 The directions shown are from the first end 21a to the second end 21b. That is, since the electrical length of the first radiating stub 21 is λ1 / 2, which is 1 / 2 of the wavelength corresponding to the first frequency band, the current distributed on the first radiating stub 21 corresponds to half a cycle, that is, the current of the positive half cycle or the current of the negative half cycle. Thus, the current direction is the same, which satisfies the current distribution mode of the radiation mode.

[0053] Please see Figure 4 This is a schematic diagram showing the current distribution of the first antenna element 2 of the electronic device 100 in some embodiments of this application operating in the second frequency band. Figure 4It can also be used as Figure 2 The diagram shows the current distribution of the first antenna unit 2 operating in the second frequency band, obtained from simulation testing using the electronic device 100 shown as an example.

[0054] As mentioned above, the first antenna element 2, through the first stub portion 211 and the first parasitic stub 221, also cooperates to support the transmission and reception of electromagnetic wave signals in the second frequency band. Figure 4 As shown, the current i2 in the second frequency band is mainly distributed on the first branch portion 211 and the first parasitic branch 221.

[0055] In some embodiments, specifically, the first feed source 23 first excites the first stub portion 211 to generate a current i2, and then couples the first stub portion 211 to excite the first parasitic stub 221 to generate a corresponding current i2. Since the third end 221a of the first parasitic stub 221, which is an open circuit, is close to the first stub portion 211, while the fourth end 221b, which is a grounded end, is far from the first stub portion 211, the current i2 generated by the excitation of the first parasitic stub 221 will have the same direction as the current i2 in the first stub portion 211. For example, as... Figure 4 As shown, the direction of the current i2 generated on the first stub portion 211 is from the first end 21a to the first feed point F1, while the first parasitic stub 221 is excited to generate a current i2 from the fourth end 221b, which is the ground end, to the third end 221a, which is the open end. The current directions of the two are the same.

[0056] Specifically, for two spaced stubs, when the directions of the currents generated after these two stubs are excited are the same, the radiation mode can be effectively excited, that is, the conditions for operating in the radiation mode are met. Therefore, the first stub portion 211 and the first parasitic stub 221 cooperate to operate in the radiation mode, thereby supporting the transmission and reception of electromagnetic wave signals in the second frequency band.

[0057] In some embodiments, the sum of the electrical lengths of the first stub portion 211 and the first parasitic stub 221 is approximately λ2 / 2, where λ2 is half the wavelength corresponding to the second frequency band. Thus, the first stub portion 211 and the first parasitic stub 221 can cooperate to operate in radiation mode, specifically in half-wavelength resonant mode, to support the transmission and reception of electromagnetic wave signals in the second frequency band.

[0058] Please see Figure 5 This is a schematic diagram showing the current distribution of the first antenna element 2 of the electronic device 100 in some embodiments of this application operating in the third frequency band. Figure 5 It can also be used as Figure 2 The schematic diagram of the current distribution of the first antenna unit 2 operating in the third frequency band is obtained by simulation test using the electronic device 100 shown as an example.

[0059] As mentioned above, the first antenna element 2 supports the transmission and reception of electromagnetic wave signals in the third frequency band through cooperation between the second stub portion 212 and the second parasitic stub 222. Figure 5 As shown, the current i3 in the third frequency band is mainly distributed on the second branch 212 and the second parasitic branch 222.

[0060] In some embodiments, specifically, the first feed source 23 first excites the second stub portion 212 to generate a current i3, and then couples the second parasitic stub 222 with the second stub portion 212 to generate a corresponding current i3. Since the fifth terminal 222a of the second parasitic stub 222, which is an open circuit, is close to the second stub portion 212, while the sixth terminal 222b, which is a grounded terminal, is far from the second stub portion 212, the current i3 generated by the excitation of the second parasitic stub 222 will have the same direction as the current i3 in the second stub portion 212. For example, as... Figure 5 As shown, the direction of the current i3 generated on the second stub portion 212 is from the first feed point F1 to the second end 21b, while the second parasitic stub 222 is excited to generate a current i3 from the fifth end 222a (which is an open circuit end) to the sixth end 222b (which is a grounded end). The current directions of the two are the same.

[0061] As mentioned earlier, for two spaced stubs, when the directions of the currents generated after the two stubs are excited are the same, the radiation mode can be effectively excited, that is, the conditions for operating in the radiation mode are met. Therefore, the first stub portion 211 and the first parasitic stub 221 cooperate to operate in the radiation mode, thereby supporting the transmission and reception of electromagnetic wave signals in the second frequency band.

[0062] In some embodiments, the sum of the electrical lengths of the first stub portion 211 and the first parasitic stub 221 is approximately λ2 / 2, where λ2 is half the wavelength corresponding to the second frequency band. Thus, the second stub portion 212 and the second parasitic stub 222 can cooperate to operate in radiation mode, specifically in half-wavelength resonant mode, to support the transmission and reception of electromagnetic wave signals in the third frequency band.

[0063] In this application, the electrical lengths of the first branch portion 211, the first parasitic branch 221, and the second parasitic branch 222 can be the electrical lengths of the branches themselves, for example, equal to the physical lengths of the branches themselves. Alternatively, the electrical lengths of the first branch portion 211, the first parasitic branch 221, and the second parasitic branch 222 can also be the equivalent electrical lengths under the matching of the corresponding matching units.

[0064] That is, in this application, the electrical length of a certain branch can be the same as the physical length of the branch, or, in some embodiments, the branch can also be connected to a matching unit, and the electrical length of the branch can also be the equivalent electrical length under the cooperation of the matching unit.

[0065] When a stub is connected to a matching unit, the matching unit can be connected between the corresponding feed source and feed point, or between the ground terminal and ground, thereby achieving corresponding matching adjustment so that the electrical length of the stub meets the resonance requirements of the corresponding frequency band. The matching unit may include capacitors and / or inductors; for example, it may include multiple capacitors and / or inductors connected in series or parallel.

[0066] Among them, the present application Figure 1 and Figure 2 The diagram illustrates the first antenna unit 2 excluding the matching unit.

[0067] In some embodiments, the first frequency band is lower than the second frequency band, and the second frequency band is lower than the third frequency band.

[0068] That is, in some embodiments, the first radiating branch 21 supports a lower frequency band than both the second and third frequency bands. Therefore, the wavelength corresponding to the first frequency band is longer than the wavelengths corresponding to the second and third frequency bands, while the wavelength corresponding to the third frequency band is the shortest. Thus, the electrical length of the first radiating branch 21 supporting the first frequency band is the longest, meaning the physical length of the first radiating branch 21 is the longest. Since the second branch portion 212 of the first radiating branch 21 and the second parasitic branch 222 cooperate to support the third frequency band, the overall physical length of the second branch portion 212 and the second parasitic branch 222 of the first radiating branch 21 is the shortest, resulting in a very short physical length for the second branch portion 212. This means that the first branch portion 211 constitutes most of the region of the first radiating branch 21. Therefore, the length of the first stub portion 211 will be relatively large. As mentioned above, the longer first stub portion 211 is positioned at the location corresponding to the functional device 1, which allows the larger functional device to be positioned close to it. Since there is no need for power supply and grounding, the functional device 1 can be positioned very close to meet the internal layout requirements of the electronic device 100. Furthermore, an antenna stub can still be set at this location to achieve the corresponding frequency band without wasting space.

[0069] As previously mentioned, since the first radiating branch 21 operates in radiation mode, specifically a half-wavelength resonant mode, and the first branch portion 211 and the first parasitic branch also operate in half-wavelength resonant mode, as do the second branch portion 212 and the second parasitic branch 222, their electrical lengths are all approximately half the corresponding frequency band. Therefore, in some embodiments, when the first frequency band is lower than the second frequency band, and the second frequency band is lower than the third frequency band, the electrical length of the first radiating branch 21 is longer than the sum of the electrical lengths of the first branch portion 211 and the first parasitic branch, and the sum of the electrical lengths of the first branch portion 211 and the first parasitic branch is greater than the sum of the electrical lengths of the second branch portion 212 and the second parasitic branch 222. When these branches are not connected to the matching unit, that is, the physical length of the first radiating branch 21 is longer than the sum of the physical lengths of the first branch portion 211 and the first parasitic branch, and the sum of the physical lengths of the first branch portion 211 and the first parasitic branch is greater than the sum of the physical lengths of the second branch portion 212 and the second parasitic branch 222.

[0070] The physical length of the aforementioned branches is the length along their respective extension directions, that is, the length of the longest side of these branches.

[0071] In this application, "A" frequency band is lower than "B" frequency band, which means that the highest value of the frequency range corresponding to A frequency band is lower than the lowest value of the frequency range corresponding to B frequency band, or that the center frequency corresponding to A frequency band is lower than the center frequency corresponding to B frequency band.

[0072] In some embodiments, the first frequency band is a mid-frequency band, such as the B3 / N3 band or the B1 / N1 band; the second frequency band is a high-frequency band, such as the B41 / N41 band or the B40 / N40 band; and the third frequency band is a 5G NR band including N77, N78, and N79.

[0073] B3 and N3 refer to the same frequency band. In 4G communication, it is called the B3 band, while in 5G communication it is called the N3 band. The only difference is the name. Similarly, B1 and N1, as well as B41 and N41, are the same.

[0074] In this application, the 5G NR band refers to a 5G communication band with a frequency higher than 3GHz, such as the aforementioned N77, N78, N79 bands, etc.

[0075] Obviously, in some embodiments, the first frequency band, the second frequency band, and the third frequency band can also be other suitable frequency bands. For example, the first frequency band can also be a low frequency band, the second frequency band can also be a WiFi 2.4G frequency band, the third frequency band can also be a WiFi 5G frequency band, and so on.

[0076] In some embodiments, such as Figure 2 As shown, the electronic device 100 includes a top end D1, a bottom end D2, and two side ends D3. The first radiating branch 21, the first parasitic branch 221, and the second parasitic branch 222 of the first antenna unit 2 are disposed on one of the side ends D3.

[0077] That is, in some embodiments, taking the first radiating branch 21, the first parasitic branch 221, and the second parasitic branch 222 as examples, the first radiating branch 21, the first parasitic branch 221, and the second parasitic branch 222 can be set on one of the side ends D3. Since the side end D3 of the electronic device 100 is relatively long, it can meet the setting requirements of the three branches.

[0078] In some embodiments, such as Figure 2As shown, the first parasitic branch 221 is disposed on the side of the first radiating branch 21 near the bottom end D2, and the second parasitic branch 222 is disposed on the side of the first radiating branch 21 near the top end D1. The second parasitic branch 222, the first radiating branch 21, and the first parasitic branch 221 are arranged sequentially along the direction from the top end D1 to the bottom end D2 of the electronic device 100, and the extension direction of the second parasitic branch 222, the first radiating branch 21, and the first parasitic branch 221 is the same as the arrangement direction.

[0079] That is, in some embodiments, such as Figure 2 As shown, the first radiating branch 21, the first parasitic branch 221, and the second parasitic branch 222 are all straight strips and are arranged sequentially from the top D1 to the bottom D2 of the electronic device 100. The extension direction of the first radiating branch 21, the first parasitic branch 221, and the second parasitic branch 222 is the same as the arrangement direction of the second parasitic branch 222, the first radiating branch 21, and the first parasitic branch 221, that is, from the top D1 to the bottom D2, and they are roughly arranged in a "I" shape.

[0080] In some embodiments, such as Figure 2 As shown, the electronic device 100 also includes a battery compartment 131, in which a rechargeable battery 132 is placed. The battery compartment 131 is located on the side of the functional device 1 near the bottom end D2, and the first parasitic branch 221 is at least partially opposite the battery compartment 131.

[0081] Since the battery compartment 131 is generally a certain distance from the edge of the electronic device 100, such as the side end D3, and this distance satisfies the normal setting of the power supply structure and grounding structure, the first parasitic branch 221 is at least partially opposite the battery compartment 131, and the space of the battery compartment 131 facing the side end D3 can be reasonably utilized.

[0082] In this application, the use of directional terms such as "top" and "bottom" when describing the electronic device 100 is primarily based on the orientation of the device when held and used by the user. "Top" refers to the position facing the top of the electronic device 100, and "bottom" refers to the position facing the bottom. This does not imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the orientation of the electronic device 100 in a real-world application scenario. In some embodiments, the bottom end D2 of the electronic device 100 is the end with a headphone jack and a USB port, and the top end D1 is the opposite end to the end with the headphone jack and USB port, or it may refer to the end with a camera, receiver, etc.

[0083] In some embodiments, such as Figure 2 As shown, the fourth end 221b of the first parasitic stub 221, which is the grounding end, extends further away from the third end 221a to form an extension stub Z1. In some embodiments, the extension stub has a structure with one end open and the other end grounded through the third end 221a. The extension stub can also be connected to other feed sources and, under the excitation of other feed sources, support the transmission and reception of electromagnetic wave signals in at least one other frequency band.

[0084] That is, the first parasitic branch 221 can also share a branch with the extended branch Z1, and be isolated from each other by grounding through the third end 221a, and the extended branch Z1 can also be used as a radiating branch to support more frequency bands. Details will be explained later.

[0085] In some embodiments, the projection of at least the side of the functional device 1 near the first radiating stub 21 onto the first radiating stub 21 is located in a target area outside the first feed point F1 of the first radiating stub 21, meaning that the projection of at least the side of the functional device 1 toward the first radiating stub 21 onto the first radiating stub 21 is located in the target area, that is, within the first stub portion 211.

[0086] In some embodiments, the functional device 1 is square. That is, when the projection of the functional device 1 in the direction perpendicular to the display screen of the electronic device 100 is square, the side of the functional device 1 facing the first radiating branch 21 can be parallel to the first radiating branch 21. In this case, the entire projection of the functional device 1 on the first radiating branch 21 will be located within the target area. In some embodiments, when the projection of the functional device 1 in the direction perpendicular to the display screen of the electronic device 100 is not square, for example, it is trapezoidal, the short side of the functional device 1 can also face the first radiating branch 21. In this case, it is sufficient that the short side of the functional device 1 facing the first radiating branch 21 is located within the target area, because the functional device 1 will still form a clearance space outside the short side, allowing for the installation of a power supply structure or a grounding structure.

[0087] Therefore, in this application, it is sufficient to ensure that the projection of at least the side of the functional device 1 near the first radiating branch 21 onto the first radiating branch 21 is located in the target area outside the first feed point F1 of the first radiating branch 21.

[0088] In some embodiments, the functional device 1 includes a cooling fan.

[0089] That is, in some embodiments, the functional device 1 may include a cooling fan as a heat dissipation device.

[0090] As electronic devices 100 become increasingly powerful, many users run various large games or software on them, which often leads to excessive heat generation. In this application, by adding a cooling fan to the electronic device 100, the heat dissipation effect can be greatly improved.

[0091] Generally, cooling fans need to be positioned close to the edge of the electronic device 100 to exhaust air through the ventilation holes on the edge of the electronic device 100, thus achieving air cooling. Therefore, the distance between the cooling fan and the side end D3 of the electronic device 100 is very small, for example, only about 1.5 mm. For most current antenna stub placements and the frame of the electronic device 100, this distance is insufficient to accommodate the grounding and / or feeding structures of the antenna stubs, making it difficult to achieve antenna functionality. In particular, cooling fans typically have metal components; embedding the cooling fan significantly affects the feeding and grounding positions of the antenna stubs due to the metal components within the fan body.

[0092] In this application, as described above, the area directly opposite the edge of the first radiating branch 21 to the functional device 1 near the first radiating branch 21 does not include connection points such as the first feed point F1; that is, it only includes the first radiating branch 21 itself. The first feed point F1 is located outside the target area. Therefore, even if the functional device 1, i.e., the cooling fan, is close to the first radiating branch 21, it does not affect the feed connection of the first feed point F1. Therefore, the electronic device 100 of this application can place the first antenna unit 2 near the functional device 1, making full use of space.

[0093] In some embodiments, the functional device 1 may also include other devices, such as a camera or other similar structures.

[0094] Please see Figure 6 This is a plan view illustrating a further structure of the electronic device 100 in some embodiments of this application.

[0095] Among them, such as Figure 6As shown, in some embodiments, the electronic device 100 includes multiple antenna units 200, which include the first antenna unit 2 and other antenna units. That is, the electronic device 100 includes other antenna units besides the first antenna unit 2. The frequency bands supported by the electronic device 100 include mid-to-high frequency bands and 5G NR bands. Multiple antenna units 200 supporting the mid-to-high frequency bands are distributed on the four sides of the electronic device 100, and multiple antenna units 200 supporting the 5G NR bands are also distributed on the four sides of the electronic device 100.

[0096] Therefore, in this application, there are multiple antenna units 200 supporting mid-to-high frequency bands, which are distributed on the four sides of the electronic device 100. There are also multiple antenna units 200 supporting 5G NR bands, which are distributed on at least three sides of the electronic device 100. Thus, when the electronic device 100 is held and used by a user, it can be ensured that important frequency bands such as mid-to-high frequency bands and 5G NR bands are not all held, thus ensuring communication performance.

[0097] In this application, the statement that an antenna unit 200 supports a certain frequency band means that the antenna unit supports a certain frequency band, that is, the frequency band supported by the antenna unit includes a certain frequency band, and does not mean that the antenna unit 200 only supports a certain frequency band, but can also support other frequency bands.

[0098] In some embodiments, multiple antenna elements 200, including the first antenna element 2, simultaneously support mid-to-high frequency bands and 5G NR bands. That is, in some embodiments, multiple antenna elements 200, including the first antenna element 2, simultaneously support mid-to-high frequency bands and 5G NR bands.

[0099] In some embodiments, the antenna unit 200 supporting the mid-to-high frequency band includes four antenna units, thereby forming a 4*4 MIMO antenna system for the mid-to-high frequency band. In some embodiments, the antenna unit supporting the 5G NR band also includes four antenna units, thereby forming a 4*4 MIMO antenna system for the 5G NR band, which can effectively improve the communication performance of the mid-to-high frequency band and the 5G NR band.

[0100] In some embodiments, the frequency band supported by the electronic device 100 further includes a low-frequency band, and the plurality of antenna elements 200 include at least two antenna elements 200 supporting the low-frequency band. The at least two antenna elements 200 supporting the low-frequency band form a 2*2 MIMO antenna system for the low-frequency band, which can effectively improve the communication performance of the low-frequency band. As described above, the electronic device 100 includes a top end D1, a bottom end D2, and two side ends D3. One of the at least two antenna elements 200 supporting the low-frequency band is located at the middle position of one of the side ends D3, and the other is located at the position of the other side end D3 and the bottom end D2.

[0101] In some embodiments, the frequency bands supported by the electronic device 100 further include WiFi bands and GPS bands. The WiFi bands include WiFi 2.4G bands and WiFi 5G bands, and the GPS bands include at least the GPS L1 band. The antenna units 200 supporting the WiFi bands include multiple units and are distributed at least on two sides of the electronic device 100. The antenna units 200 supporting the GPS bands are distributed on the side of the electronic device 100 located at the top D1.

[0102] In some embodiments, the antenna unit 200 supporting the WiFi band includes at least two, and each antenna unit 200 supporting the WiFi band supports both the WiFi 2.4G band and the WiFi 5G band. Therefore, the at least two antenna units 200 supporting the WiFi 2.4G band and the WiFi 5G band form a 2*2 MIMO antenna system for the WiFi 2.4G band and the WiFi 5G band, which can effectively improve the communication performance of the WiFi 2.4G band and the WiFi 5G band.

[0103] In some embodiments, the antenna units 200 supporting the WiFi band include multiple units, and are distributed at least on two adjacent sides of the electronic device 100. This ensures that, in different holding states of the electronic device 100, such as landscape or portrait holding, at least one antenna unit 200 supporting the WiFi band is not fully held, thus ensuring communication performance for both the WiFi 2.4G and WiFi 5G bands.

[0104] In some embodiments, one antenna unit 200 supporting the WiFi band is located in the middle of the side end D3, and at least two antenna units 200 supporting both mid-to-high frequency bands and 5G NR bands are also located in the middle of one side end D3. This ensures that the antenna is not completely gripped when the user holds it with one hand or both hands, which helps to reduce the impact on the human body and further improves the antenna performance of the WiFi band, mid-to-high frequency band and 5G NR band.

[0105] In some embodiments, such as Figure 6 As shown, the electronic device also includes a plurality of other antenna units, including second antenna unit 3, third antenna unit 4, fourth antenna unit 5, fifth antenna unit 6, sixth antenna unit 7, seventh antenna unit 8, eighth antenna unit 9, ninth antenna unit 10 and tenth antenna unit 11. That is, the plurality of antenna units 200 includes the first antenna unit 2, and also includes second antenna unit 3, third antenna unit 4, fourth antenna unit 5, fifth antenna unit 6, sixth antenna unit 7, seventh antenna unit 8, eighth antenna unit 9, ninth antenna unit 10 and tenth antenna unit 11. Specifically, the first antenna unit 2 supports low, mid, and high frequency bands as well as the 5G NR band; the second antenna unit 3 supports low frequency bands as well as the 5G NR band; the third antenna unit 4 also supports low frequency bands as well as the 5G NR band; the fourth antenna unit 5, the fifth antenna unit 6, and the sixth antenna unit 7 all support mid-to-high frequency bands as well as the 5G NR band; the seventh antenna unit 8 supports the GPS L1 band as well as the 5G NR band; the eighth antenna unit 9 and the ninth antenna unit 10 both support the WiFi 2.4G band as well as the WiFi 5G band; and the tenth antenna unit 11 supports the 5G NR band.

[0106] That is, in some embodiments, the electronic device 100 may include 10 antenna units 200 to achieve full coverage of low, medium and high frequencies, 5G NR band, GPS band and WiFi band.

[0107] In some embodiments, as described above, the electronic device 100 includes a top end D1, a bottom end D2, and two side ends D3. The side ends D3 include a first side end D31 and a second side end D32. The first antenna unit 2 is disposed on the first side end D31, the second antenna unit 3 is disposed on the first side end D31 and the bottom end D2, the third antenna unit 4 is disposed on the second side end D32, the fourth antenna unit 5 is disposed on the top end D1 and the second side end D32, the fifth antenna unit 6 is disposed on the bottom end D2, the sixth antenna unit 7 is disposed on the second side end D32, the seventh antenna unit 8 is disposed on the top end D1, the eighth antenna unit 9 is disposed on the top end D1 and the first side end D31, the ninth antenna unit 10 is disposed on the first side end D31, and the tenth antenna unit 11 is disposed on the second side end D32.

[0108] The second antenna element 3 is disposed at the first side end D31 and the bottom end D2, meaning that part of the second antenna element 3 is disposed at the first side end D31 and part is disposed at the bottom end D2, that is, disposed at... Figure 6 The position is shown in the lower left corner of the viewpoint. Similarly, the fourth antenna unit 5 is disposed at the top D1 and the second side D32, meaning that a portion of the fourth antenna unit 5 is disposed at the top D1 and a portion is disposed at the second side D32. The eighth antenna unit 9 is disposed at the top D1 and the first side D31, also meaning that a portion of the eighth antenna unit 9 is disposed at the top D1 and a portion is disposed at the first side D31.

[0109] In this application, "antenna unit 200 is disposed at a certain position in electronic device 100" means that the radiating branch of antenna unit 200 is disposed at a certain position in electronic device 100. When antenna unit 200 also includes parasitic branches, "antenna unit 200 is disposed at a certain position in electronic device 100" means that both the radiating branch and the parasitic branch of antenna unit 200 are disposed at a certain position in electronic device 100. For example, in this application, when the first antenna unit 2 includes the first radiating branch 21, the first parasitic branch 221, and the second parasitic branch 222, and the first antenna unit 2 is disposed at the first side end D31, specifically, the first radiating branch 21, the first parasitic branch 221, and the second parasitic branch 222 of the first antenna unit 2 are disposed at the first side end D31.

[0110] in, Figure 1 , Figure 2 as well as Figure 6The diagram shows the electronic device 100 viewed from the back and the side away from the display screen. The first side end D31 is the left side end in the view, and the second side end D32 is the right side end in the view.

[0111] In some embodiments, such as Figure 6 As shown, the second antenna element 3 includes a second feed 31 and a second radiating stub 32. The second radiating stub 32 includes a second feed point F2 and two opposing ends: a first open-circuit end 32a and a first ground end 32b for grounding. The second feed point F2 is located between the first ground end 32b and the first open-circuit end 32a of the second radiating stub 32. The portion between the first ground end 32b and the first open end 32a of the second radiating stub 32, i.e., the entire second radiating stub 32, supports the transmission and reception of low-frequency electromagnetic wave signals under the excitation of the second feed 31. The second radiating stub 32 is disposed at the bottom end D2 and the first side end D31 of the electronic device 100.

[0112] The portion between the first ground terminal 32b and the first open terminal 32a of the second radiating stub 32 forms an IFA (Inverted F antenna) antenna structure. Under the excitation of the second feed 31, the portion between the first ground terminal 32b and the first open terminal 32a of the second radiating stub 32 supports the transmission and reception of low-frequency electromagnetic wave signals.

[0113] In particular, since the second radiating stub 32 of the second antenna unit 3 is located at the corner of the electronic device 100 between the bottom end D2 and the first side end D31, it can ensure that it is not completely gripped when the user holds it with one hand or two hands, which helps to reduce the impact on the human body and further improve the antenna performance of the low frequency band. Moreover, since the stubs required for low frequencies are relatively long, by setting them at the corner position, space can be freed up for other antenna units, which is beneficial to the overall layout.

[0114] In some embodiments, the equivalent electrical length of the portion between the first ground terminal 32b and the first open terminal 32a of the second radiating stub 32 is 1 / 4 of the wavelength of the low-frequency band, and can resonate in the low-frequency band to support the transmission and reception of electromagnetic wave signals in the low-frequency band.

[0115] In some embodiments, the second feed point F2 of the second radiating stub 32 is located close to the first open end 32a, and the stub portion between the second feed point F2 of the second radiating stub 32 and the first open end 32a also supports the transmission and reception of electromagnetic wave signals in the 5G NR band under the excitation of the second feed source 31.

[0116] That is, in some embodiments, the equivalent electrical length of the stub portion between the second feed point F2 of the second radiating stub 32 and the first open terminal 32a meets the resonance requirements of the 5G NR band, for example, it is 1 / 4 of the wavelength corresponding to the 5G NR band, thereby supporting resonance in the 5G NR band.

[0117] Therefore, as mentioned above, the second antenna unit 3 can simultaneously support low-frequency bands and 5G NR bands.

[0118] like Figure 6 As shown, the third antenna element 4 includes a third feed 41 and a third radiating stub 42. The third radiating stub 42 includes a third feed point F3 and two opposing ends: a second open-circuit terminal 42a (open circuit) and a second ground terminal 42b (grounding). The third feed point F3 is located between the second ground terminal 42b and the second open-circuit terminal 42a of the third radiating stub 42. The portion between the second ground terminal 42b and the second open-circuit terminal 42a of the third radiating stub 42, i.e., the entire third radiating stub 42, supports the transmission and reception of low-frequency electromagnetic wave signals under the excitation of the third feed 41. The third radiating stub 42 is located at the second side terminal D32 of the electronic device 100.

[0119] In some embodiments, such as Figure 6 As shown, the third radiating branch 42 is located at the middle position of the second side end D32 of the electronic device 100, that is, both ends of the third radiating branch 42 are at a certain distance from the top end D1 and the bottom end D2 of the electronic device 100. Therefore, the third radiating branch 42 of the third antenna unit 4 is located at one of the side ends D3, that is, at the middle position of the second side end D32, which is relatively far from the top end D1 and the bottom end D2 of the electronic device 100. This ensures that the device is not completely gripped when held with one hand or two hands, reducing the impact on the user and further improving the antenna performance in the low-frequency band.

[0120] The portion between the second ground terminal 42b and the second open terminal 42a of the third radiating stub 42 also forms an IFA antenna structure. The portion between the second ground terminal 42b and the second open terminal 42a of the third radiating stub 42 supports the transmission and reception of low-frequency electromagnetic wave signals under the excitation of the third feed source 41.

[0121] In some embodiments, the portion between the second ground terminal 42b and the second open terminal 42a of the third radiating stub 42, that is, the equivalent electrical length of the entire third radiating stub 42, is 1 / 4 of the wavelength of the low-frequency band, and can resonate in the low-frequency band to support the transmission and reception of electromagnetic wave signals in the low-frequency band.

[0122] In some embodiments, the third feed point F3 of the third radiating stub 42 is located close to the second open end 42a, and the stub portion between the third feed point F3 of the third radiating stub 42 and the second open end 42a also supports the transmission and reception of electromagnetic wave signals in the 5G NR band under the excitation of the third feed source 41.

[0123] That is, in some embodiments, the equivalent electrical length of the stub portion between the third feed point F3 of the third radiating stub 42 and the second open terminal 42a meets the resonance requirements of the 5G NR band, for example, it is 1 / 4 of the wavelength corresponding to the 5G NR band, thereby supporting resonance in the 5G NR band.

[0124] Therefore, as mentioned above, the third antenna unit 4 can also support both low-frequency bands and 5G NR bands simultaneously.

[0125] like Figure 6 As shown, the fourth antenna element 5 includes a fourth feed 51 and a fourth radiating stub 52. The fourth radiating stub 52 includes a fourth feed point F4. The fourth radiating stub 52 also includes two opposing ends: a third open-circuit terminal 52a and a third ground terminal 52b for grounding. The fourth feed point F4 is located between the third ground terminal 52b and the third open-circuit terminal 52a of the fourth radiating stub 52.

[0126] Wherein, the distance between the fourth power supply point F4 and the third open circuit terminal 52a is less than the distance between the fourth power supply point F4 and the third grounding terminal 52b, that is, the fourth power supply point F4 is closer to the third open circuit terminal 52a.

[0127] The portion between the third ground terminal 52b and the open-circuit terminal 52a of the fourth radiating stub 52, i.e., the entire fourth radiating stub 52, supports the transmission and reception of electromagnetic wave signals in the intermediate frequency band under the excitation of the fourth feed source 51. The fourth radiating stub 52 also forms an IFA antenna structure, and the portion between the third ground terminal 52b and the open-circuit terminal 52a of the fourth radiating stub 52, i.e., the entire fourth radiating stub 52, supports the transmission and reception of electromagnetic wave signals in the intermediate frequency band under the excitation of the fourth feed source 51.

[0128] In some embodiments, the portion between the third ground terminal 52b and the third open terminal 52a of the fourth radiating stub 52, i.e. the equivalent electrical length of the entire fourth radiating stub 52, is 1 / 4 of the wavelength of the intermediate frequency band, and can resonate in the intermediate frequency band to support the transmission and reception of electromagnetic wave signals in the intermediate frequency band.

[0129] Specifically, the stub portion between the third grounding terminal 52b of the fourth radiating stub 52 and the fourth feed point F4 supports the transmission and reception of electromagnetic wave signals in the high-frequency band under the excitation of the fourth feed source 51, and the stub portion between the third open terminal 52a of the fourth radiating stub 52 and the fourth feed point F4 supports the transmission and reception of electromagnetic wave signals in the 5GNR band under the excitation of the fourth feed source 51.

[0130] That is, in some embodiments, the equivalent electrical length of the stub portion between the third grounding terminal 52b of the fourth radiating stub 52 and the fourth feed point meets the resonance requirements of the intermediate frequency band, for example, it is 1 / 4 of the wavelength corresponding to the intermediate frequency band, thereby supporting resonance in the intermediate frequency band. The equivalent electrical length of the stub portion between the third open terminal 52a of the fourth radiating stub 52 and the fourth feed point meets the resonance requirements of the 5G NR band, for example, it is 1 / 4 of the wavelength corresponding to the 5G NR band, thereby supporting resonance in the 5G NR band.

[0131] Therefore, as mentioned above, the fourth antenna unit 5 can also simultaneously support mid-to-high frequency bands and 5G NR bands.

[0132] Among them, such as Figure 6 As shown, the third grounding terminal 52b of the fourth radiating branch 52 is located at the second side end D32, and the third open-circuit terminal 52a of the fourth radiating branch 52 is located at the top end D1. Thus, part of the fourth radiating branch 52 is located at the top end D1, and another part is located at the second side end D32.

[0133] like Figure 6As shown, the fifth antenna element 6 includes a fifth feed 61 and a fifth radiating stub 62. The fifth radiating stub 62 includes a fifth feed point F5. The fifth radiating stub 62 also includes two opposing ends: a fourth open-circuit terminal 62a (which is open-circuited) and a fourth ground terminal 62b (which is grounded). The fifth feed point F5 is located between the fourth ground terminal 62b and the fourth open-circuit terminal 62a of the fifth radiating stub 62.

[0134] The distance between the fifth power supply point F5 and the fourth open circuit terminal 62a is less than the distance between the fifth power supply point F5 and the fourth grounding terminal 62b, that is, the fifth power supply point F5 is closer to the fourth open circuit terminal 62a.

[0135] The portion between the fourth ground terminal 62b and the open-circuit terminal 62a of the fifth radiating stub 62, i.e., the entire fifth radiating stub 62, supports the transmission and reception of electromagnetic wave signals in the intermediate frequency band under the excitation of the fifth feed source 61. The fifth radiating stub 62 also forms an IFA antenna structure, and the portion between the fourth ground terminal 62b and the open-circuit terminal 62a of the fifth radiating stub 62, i.e., the entire fifth radiating stub 62, supports the transmission and reception of electromagnetic wave signals in the intermediate frequency band under the excitation of the fifth feed source 61.

[0136] In some embodiments, the portion between the fourth ground terminal 62b and the fourth open terminal 62a of the fifth radiating stub 62, that is, the equivalent electrical length of the entire fifth radiating stub 62, is 1 / 4 of the wavelength of the intermediate frequency band, and can resonate in the intermediate frequency band to support the transmission and reception of electromagnetic wave signals in the intermediate frequency band.

[0137] Specifically, the branch portion between the fourth grounding terminal 62b of the fifth radiating branch 62 and the fifth feed point F5 supports the transmission and reception of electromagnetic wave signals in the high-frequency band under the excitation of the fifth feed source 61, and the branch portion between the fourth open terminal 62a of the fifth radiating branch 62 and the fifth feed point F5 supports the transmission and reception of electromagnetic wave signals in the 5GNR band under the excitation of the fifth feed source 61.

[0138] That is, in some embodiments, the equivalent electrical length of the stub portion between the fourth ground terminal 62b of the fifth radiating stub 62 and the fifth feed point F5 meets the resonance requirements of the intermediate frequency band, for example, it is 1 / 4 of the wavelength corresponding to the intermediate frequency band, thereby supporting resonance in the intermediate frequency band. The equivalent electrical length of the stub portion between the fourth open terminal 62a of the fifth radiating stub 62 and the fifth feed point F5 meets the resonance requirements of the 5G NR band, for example, it is 1 / 4 of the wavelength corresponding to the 5G NR band, thereby supporting resonance in the 5G NR band.

[0139] Therefore, as mentioned above, the fifth antenna unit 6 can also simultaneously support mid-to-high frequency bands and 5G NR bands.

[0140] Among them, such as Figure 6 As shown, the fourth grounding terminal 62b of the fifth antenna element 6 is also directly connected to the adjacent stub Z2, and is isolated from each other by grounding through the fourth grounding terminal 62b. The adjacent stub Z2 can be located near the bottom end D2 of the second side end D3, and can further connect to other feed sources, thus supporting other frequency bands under the excitation of other feed sources.

[0141] Among them, such as Figure 6 As shown, the fourth open end 62a of the fifth radiating branch 62 is close to and spaced apart from the first open end 32a of the second radiating branch 32.

[0142] like Figure 6 As shown, the sixth antenna element 7 includes a sixth feed 71 and a sixth radiating stub 72. The sixth radiating stub 72 includes a sixth feed point F6. The sixth radiating stub 72 also includes two opposing ends: a fifth open-circuit terminal 72a and a fifth ground terminal 72b for grounding. The sixth feed point F6 is located between the fifth ground terminal 72b and the fifth open-circuit terminal 72a of the sixth radiating stub 72.

[0143] The distance between the sixth power supply point F6 and the fifth open circuit terminal 72a is less than the distance between the sixth power supply point F6 and the fifth grounding terminal 72b, that is, the sixth power supply point F6 is closer to the fifth open circuit terminal 72a.

[0144] The portion between the fifth ground terminal 72b and the fifth open terminal 72a of the sixth radiating stub 72, i.e., the entire sixth radiating stub 72, supports the transmission and reception of electromagnetic wave signals in the intermediate frequency band under the excitation of the sixth feed 71. The sixth radiating stub 72 also forms an IFA antenna structure, and the portion between the fifth ground terminal 72b and the fifth open terminal 72a of the sixth radiating stub 72, i.e., the entire sixth radiating stub 72, supports the transmission and reception of electromagnetic wave signals in the intermediate frequency band under the excitation of the sixth feed 71.

[0145] In some embodiments, the portion between the fifth ground terminal 72b and the fifth open terminal 72a of the sixth radiating stub 72, i.e. the equivalent electrical length of the entire sixth radiating stub 72, is 1 / 4 of the wavelength of the intermediate frequency band, and can resonate in the intermediate frequency band to support the transmission and reception of electromagnetic wave signals in the intermediate frequency band.

[0146] Specifically, the branch portion between the fifth grounding terminal 72b of the sixth radiating branch 72 and the sixth feed point F6 supports the transmission and reception of electromagnetic wave signals in the high-frequency band under the excitation of the sixth feed source 71, and the branch portion between the fifth open terminal 72a of the sixth radiating branch 72 and the sixth feed point F6 supports the transmission and reception of electromagnetic wave signals in the 5GNR band under the excitation of the sixth feed source 71.

[0147] That is, in some embodiments, the equivalent electrical length of the stub portion between the fifth ground terminal 72b of the sixth radiating stub 72 and the sixth feed point F6 meets the resonance requirements of the intermediate frequency band, for example, it is 1 / 4 of the wavelength corresponding to the intermediate frequency band, thereby supporting resonance in the intermediate frequency band. The equivalent electrical length of the stub portion between the fifth open terminal 72a of the sixth radiating stub 72 and the sixth feed point F6 meets the resonance requirements of the 5G NR band, for example, it is 1 / 4 of the wavelength corresponding to the 5G NR band, thereby supporting resonance in the 5G NR band.

[0148] Therefore, as mentioned above, the sixth antenna unit 7 can also simultaneously support mid-to-high frequency bands and 5G NR bands.

[0149] Among them, such as Figure 6 As shown, the sixth antenna element 7 is approximately located in the middle of the second side end D32. And as... Figure 6 As shown, the first antenna unit 2 is also located approximately in the middle of the first side end D31. Therefore, at least two antenna units that simultaneously support the mid-to-high frequency band and the 5G NR band are located in the middle of the corresponding side ends. Thus, as mentioned above, when the user holds it with one hand or both hands, it can be ensured that it is not completely gripped, which helps to reduce the impact on the human body and further improve the antenna performance of the mid-to-high frequency band and the 5G NR band.

[0150] like Figure 6 As shown, the seventh antenna element 8 includes a seventh feed 81 and a seventh radiating stub 82. The seventh radiating stub 82 includes a seventh feed point F7. The seventh radiating stub 82 also includes two opposing ends: a sixth open-circuit terminal 82a (which is open-circuit) and a sixth ground terminal 82b (which is grounded). The seventh feed point F7 is located between the sixth ground terminal 82b and the sixth open-circuit terminal 82a of the seventh radiating stub 82.

[0151] Wherein, the distance between the seventh feed point F7 and the sixth open terminal 82a is less than the distance between the seventh feed point F7 and the sixth ground terminal 82b, that is, the seventh feed point F7 is closer to the sixth open terminal 82a.

[0152] The portion between the sixth ground terminal 82b and the open-circuit terminal 82a of the seventh radiating stub 82, i.e., the entire seventh radiating stub 82, supports the transmission and reception of electromagnetic wave signals in the GPS frequency band, such as the GPS L1 band, under the excitation of the seventh feed 81. The seventh radiating stub 82 also forms an IFA antenna structure, and the portion between the sixth ground terminal 82b and the open-circuit terminal 82a of the seventh radiating stub 82, i.e., the entire seventh radiating stub 82, supports the transmission and reception of electromagnetic wave signals in the GPS frequency band under the excitation of the seventh feed 81.

[0153] In some embodiments, the portion between the sixth ground terminal 82b and the sixth open terminal 82a of the seventh radiating stub 82, that is, the equivalent electrical length of the entire seventh radiating stub 82, is 1 / 4 of the wavelength of the GPS frequency band, and can resonate in the GPS frequency band to support the transmission and reception of electromagnetic wave signals in the GPS frequency band.

[0154] The stub portion between the sixth open terminal 82a of the seventh radiating stub 82 and the seventh feed point F7 supports the transmission and reception of electromagnetic wave signals in the 5G NR band under the excitation of the seventh feed source 81.

[0155] That is, in some embodiments, the equivalent electrical length of the stub portion between the sixth open terminal 82a of the seventh radiating stub 82 and the seventh feed point F7 meets the resonance requirements of the 5G NR band, for example, it is 1 / 4 of the wavelength corresponding to the 5G NR band, thereby supporting resonance in the 5G NR band.

[0156] Therefore, as mentioned above, the seventh antenna unit 8 can support the GPS L1 band and the 5G NR band.

[0157] like Figure 6 As shown, the eighth antenna element 9 includes an eighth feed 91 and an eighth radiating stub 92. The eighth radiating stub 92 includes an eighth feed point F8. The eighth radiating stub 92 also includes two opposing ends: a seventh open-circuit terminal 92a (which is open-circuit) and a seventh ground terminal 92b (which is grounded). The eighth feed point F8 is located between the seventh ground terminal 92b and the seventh open-circuit terminal 92a of the eighth radiating stub 92.

[0158] Wherein, the distance between the eighth feed point F8 and the seventh open terminal 92a is less than the distance between the eighth feed point F8 and the seventh ground terminal 92b, that is, the eighth feed point F8 is closer to the seventh open terminal 92a.

[0159] The portion between the seventh ground terminal 92b and the open-circuit seventh terminal 92a of the eighth radiating stub 92, i.e., the entire eighth radiating stub 92, supports the WiFi 2.4G band under the excitation of the eighth feed source 91. The eighth radiating stub 92 also forms an IFA antenna structure, and under the excitation of the eighth feed source 91, it supports the transmission and reception of electromagnetic wave signals in the GPS band.

[0160] In some embodiments, the portion between the seventh ground terminal 92b and the seventh open terminal 92a of the eighth radiating stub 92, i.e. the equivalent electrical length of the entire eighth radiating stub 92, is 1 / 4 of the wavelength of the WiFi 2.4G band, and can resonate in the WiFi 2.4G band to support the transmission and reception of electromagnetic wave signals in the WiFi 2.4G band.

[0161] The stub portion between the seventh open terminal 92a of the eighth radiating stub 92 and the eighth feed point F8 supports the transmission and reception of electromagnetic wave signals in the WiFi 5G band under the excitation of the eighth feed source 91.

[0162] That is, in some embodiments, the equivalent electrical length of the stub portion between the seventh open terminal 92a of the eighth radiating stub 92 and the eighth feed point F8 meets the resonance requirements of the WiFi 5G band, for example, it is 1 / 4 of the wavelength corresponding to the WiFi 5G band, thereby supporting resonance in the 5G NR band.

[0163] Therefore, as mentioned above, the eighth antenna unit 9 can support the WiFi 2.4G band and the WiFi 5G band.

[0164] Among them, such as Figure 6 As shown, the seventh open terminal 92a of the eighth radiating stub 92 is located at the top D1 of the electronic device 100, and the seventh ground terminal 92b of the eighth radiating stub 92 is located at the first side terminal D31 of the electronic device 100. Thus, part of the eighth antenna element 9 is located at the top D1, and part is located at the first side terminal D31.

[0165] like Figure 6 As shown, the ninth antenna element 10 includes a ninth feed 101 and a ninth radiating stub 102. The ninth radiating stub 102 includes a ninth feed point F9. The ninth radiating stub 102 also includes two opposing ends: an eighth open-circuit terminal 102a (which is open-circuit) and an eighth ground terminal 102b (which is grounded). The ninth feed point F9 is located between the eighth ground terminal 102b and the eighth open-circuit terminal 102a of the ninth radiating stub 102.

[0166] Wherein, the distance between the ninth power supply point F9 and the eighth open circuit terminal 102a is less than the distance between the ninth power supply point F9 and the eighth grounding terminal 102b, that is, the ninth power supply point F9 is closer to the eighth open circuit terminal 102a.

[0167] Specifically, the portion between the eighth ground terminal 102b and the open-circuit terminal 102a of the ninth radiating stub 102, i.e., the entire ninth radiating stub 102, supports the WiFi 2.4G band under the excitation of the ninth feed 101. The ninth radiating stub 102 also forms an IFA antenna structure, and under the excitation of the ninth feed 101, it supports the transmission and reception of electromagnetic wave signals in the GPS band.

[0168] In some embodiments, the portion between the eighth ground terminal 102b and the eighth open terminal 102a of the ninth radiating stub 102, i.e. the equivalent electrical length of the entire ninth radiating stub 102, is 1 / 4 of the wavelength of the WiFi 2.4G band, and can resonate in the WiFi 2.4G band to support the transmission and reception of electromagnetic wave signals in the WiFi 2.4G band.

[0169] The stub portion between the eighth open terminal 102a of the ninth radiating stub 102 and the ninth feed point F9 supports the transmission and reception of electromagnetic wave signals in the WiFi 5G band under the excitation of the ninth feed source 101.

[0170] That is, in some embodiments, the equivalent electrical length of the stub portion between the eighth open terminal 102a of the ninth radiating stub 102 and the ninth feed point F9 meets the resonance requirements of the WiFi 5G band, for example, it is 1 / 4 of the wavelength corresponding to the WiFi 5G band, thereby supporting resonance in the 5G NR band.

[0171] Therefore, as mentioned above, the ninth antenna unit 10 can support the WiFi 2.4G band and the WiFi 5G band.

[0172] The ninth antenna element 10 is located approximately in the middle of the first side end D31.

[0173] Among them, such as Figure 6 As shown, the eighth grounding terminal 102b of the ninth radiating branch 102 is close to the fourth grounding terminal 221b of the first parasitic branch 221, and the ninth radiating branch 102 and the first parasitic branch 221 share a branch.

[0174] That is, the extended branch Z1 formed by the fourth end 221b of the first parasitic branch 221 (which is the grounding end) extending away from the third end 221a can be the ninth radial branch 102. The ninth radial branch 102 shares a branch with the first parasitic branch 221 and is isolated by grounding through the eighth grounding end 102b and the fourth end 221b (which is the grounding end). Wherein, as Figure 6 As shown, there may be a gap between the eighth grounding terminal 102b and the fourth grounding terminal 221b, and the branch between the eighth grounding terminal 102b and the fourth grounding terminal 221b is considered as grounding.

[0175] The eighth grounding terminal 102b and the fourth grounding terminal 221b are spaced apart, which allows the position of the eighth grounding terminal 102b and / or the fourth grounding terminal 221b to be adjusted within a certain range, so as to better resonate in the corresponding frequency band.

[0176] like Figure 6 As shown, the tenth antenna element 11 includes a tenth feed 111 and a tenth radiating stub 112. The tenth radiating stub 112 includes a tenth feed point F10. The tenth radiating stub 112 also includes two opposing ends: a ninth open-circuit terminal 112a (which is open-circuit) and a ninth ground terminal 112b (which is grounded). The tenth feed point F10 is located between the ninth ground terminal 112b and the ninth open-circuit terminal 112a of the tenth radiating stub 112.

[0177] In some embodiments, the portion between the ninth ground terminal 112b and the ninth open terminal 112a of the tenth radiating stub 112, that is, the entire tenth radiating stub 112, supports the transmission and reception of electromagnetic wave signals in the 5G NR band under the excitation of the tenth feed 111.

[0178] That is, the portion between the ninth ground terminal 112b and the ninth open terminal 112a of the tenth radiating stub 112, which is also the equivalent electrical length of the entire tenth radiating stub 112, is 1 / 4 of the wavelength of the 5G NR band, and can resonate in the 5G NR band to support the transmission and reception of electromagnetic wave signals in the 5G NR band.

[0179] Therefore, as mentioned above, the tenth antenna element 11 can support the 5G NR band.

[0180] In some embodiments, such as Figure 6As shown, the ninth grounding terminal 112b of the tenth radiating branch 112 is directly connected to the fifth grounding terminal 72b of the sixth radiating branch 72. That is, the tenth radiating branch 112 and the sixth radiating branch 72 share a branch and are isolated from each other by grounding through the ninth grounding terminal 112b and the fifth grounding terminal 72b.

[0181] Therefore, in this application, through the above structure, the first antenna unit 2 supports at least low, mid, and high frequency bands and the 5G NR band; the second antenna unit 3 supports at least low frequency bands and the 5G NR band; the third antenna unit 4 also supports at least low frequency bands and the 5G NR band; the fourth antenna unit 5, the fifth antenna unit 6, and the sixth antenna unit 7 all support at least mid-to-high frequency bands and the 5G NR band; the seventh antenna unit 8 supports at least the GPS L1 band and the 5G NR band; the eighth antenna unit 9 and the ninth antenna unit 10 both support at least the WiFi 2.4G band and the WiFi 5G band; and the tenth antenna unit 11 supports at least the 5G NR band.

[0182] Please see Figure 7 This is a schematic diagram illustrating the return loss of the first antenna element 2 of the electronic device 100 in some embodiments of this application when operating in the mid-to-high frequency band and the 5G NR band. Figure 7 It can be used as Figure 2 or Figure 6 The diagram shows the return loss obtained from simulation tests of the first antenna unit 2 of the electronic device 100 operating in the mid-to-high frequency band and the 5G NR band.

[0183] In a certain frequency band, the frequency corresponding to the lowest point of the same input return loss curve is the resonant frequency. The lower the input return loss, the lower the loss at that resonant frequency, and the higher the antenna radiation efficiency.

[0184] in, Figure 7 In this context, the mid-frequency bands include the B3 band (resonant frequency approximately 1.8 GHz) and the B1 band (resonant frequency approximately 2.1 GHz), while the high-frequency bands include the B40 band (resonant frequency approximately 2.3 GHz) and the B41 band (resonant frequency approximately 2.5 GHz). The 5G NR band is illustrated using the N78 band (resonant frequency approximately 3.5 GHz) as an example.

[0185] Among them, from Figure 7 It can be seen that the first antenna element 2 of the electronic device 100 of this application has low return loss in both the mid-high frequency band and the 5GNR band, with a maximum of only -4dB, indicating low loss.

[0186] Please see Figure 8This diagram illustrates the radiation efficiency and overall system efficiency of the first antenna element 2 of the electronic device 100 in some embodiments of this application when operating in the mid-to-high frequency band and the 5G NR band. Figure 8 It can be used as Figure 2 or Figure 6 The diagram shows the radiation efficiency and overall system efficiency of the first antenna unit 2 of the electronic device 100, which is obtained from simulation tests conducted in the mid-to-high frequency band and the 5G NR band.

[0187] In a certain frequency band, the frequency corresponding to the highest point of the same radiation efficiency curve or the total system efficiency curve is the resonant frequency. The lower the input return loss, the lower the loss at that resonant frequency, and the higher the antenna radiation efficiency.

[0188] in, Figure 8 The diagram illustrates the radiation efficiency curve Sr1 and the overall system efficiency curve St1. Among them, Figure 8 The diagram also includes the mid-frequency bands, namely the B3 band (resonant frequency of approximately 1.8 GHz) and the B1 band (resonant frequency of approximately 2.1 GHz), and the high-frequency bands, namely the B40 band (resonant frequency of approximately 2.3 GHz) and the B41 band (resonant frequency of approximately 2.5 GHz). The 5G NR band is illustrated using the N78 band (resonant frequency of approximately 3.5 GHz) as an example.

[0189] from Figure 8 It can be seen that the first antenna element 2 of the electronic device 100 of this application has high overall system efficiency and radiation efficiency in the mid-to-high frequency band and the 5G NR band, with the lowest being only about -4dB, indicating high radiation efficiency.

[0190] Therefore, it can be seen that, through the structure of the first antenna unit 2 in this application, not only can the first radiating branch 21 be set at least in a position close to the functional device 1, but the radiation performance of the first antenna unit 2 in each frequency band can also be ensured.

[0191] Please see Figure 9 This is a data graph showing the radiation efficiency of the first antenna unit 2 operating in various frequency bands when the electronic device 100 in some embodiments of this application is in different usage scenarios. Figure 9 It can also be used as Figure 2 or Figure 6 The diagram shows the radiation efficiency of the first antenna unit 2 of the electronic device 100, which is obtained from simulation tests conducted in the mid-to-high frequency band and the 5G NR band.

[0192] in, Figure 9The diagram illustrates the radiation efficiency of the first antenna unit 2 operating in the mid-to-high frequency band and the 5G NR band in both free-space (FS) and user-handed scenarios (specifically, USB NR, held with both hands and the USB port facing right). Figure 9 The mid-frequency bands include the B3 and B1 bands, and the high-frequency bands include the B40 and B41 bands. The 5G NR bands are illustrated using the N78 band as an example.

[0193] like Figure 9 As shown, in the free space scenario (FS), the radiative efficiency (RFE) is -4.3 dB for the B3 band, -4.3 dB for the uplink band (B1T) of the B1 band, and -4.5 dB for the downlink band (B1R). The RFE for the B40 band is -4.3 dB, the B41 band is -5.4 dB, and the N78 band is -4.1 dB. In the user-handheld scenario (USBR), the RFE is -4.5 dB for the B3 band, -4.5 dB for the uplink band (B1T) of the B1 band, and -5.5 dB for the downlink band (B1R). The RFE for the B40 band is -5.5 dB, the B41 band is -6.4 dB, and the N78 band is -5.2 dB.

[0194] As can be seen from the above, the first antenna element 2 of this application has high radiation efficiency in both the mid-to-high frequency band and the 5G NR band under free space (FS) and user handheld (USBR) scenarios, and the overall antenna performance is good.

[0195] Please see Figure 10 This is a data graph showing the radiation efficiency of the second antenna unit 3 operating in the corresponding frequency band when the electronic device 100 in some embodiments of this application is in different usage scenarios. Figure 10 It can be used as Figure 6 The diagram shows the radiation efficiency of the second antenna unit 3 of the electronic device 100, which is operated in the low-frequency band and obtained from simulation tests.

[0196] in, Figure 10 The diagram illustrates the radiation efficiency of the second antenna unit 3 operating in the low-frequency band under both free space (FS) and user-handheld scenarios.

[0197] in, Figure 10 The example provided illustrates the low-frequency bands including B5, B8, B20, and B28.

[0198] When the second antenna element 3 is in a free-space scenario where it is not being held, the B5 band, such as Figure 10As shown in column B5(FS), the radiative efficiency is approximately -8dB; the B8 band, as... Figure 10 As shown in column B8(FS), the radiative efficiency is approximately -8dB; the B20 band, as... Figure 10 As shown in the B20(FS) column, the radiative efficiency is approximately -8dB; the B28 band, as... Figure 10 As shown in column B28(FS), the radiation efficiency is approximately -9dB. When the second antenna element 3 is in a user-held scenario (where, Figure 10 Specifically, in the scenario where the user holds the device with their right hand (BHHR), the B5 band, such as... Figure 10 As shown in the B5 (BHHR) column, the radiative efficiency is approximately -14.5 dB; the B8 band, as... Figure 10 As shown in the B8 (BHHR) column, the radiative efficiency is approximately -14.5 dB, in the B20 band, as... Figure 10 As shown in the B20 (BHHR) column, the radiative efficiency is approximately -15 dB; the B28 band, as... Figure 10 As shown in the B28(BHHR) column, the radiation efficiency is approximately -15.5dB.

[0199] from Figure 10 It can be seen that the radiation efficiency of the second antenna element 3 is relatively high in free space, but the radiation efficiency is somewhat affected in the right-hand holding scenario.

[0200] Please see Figure 11 This is a radiation efficiency data diagram showing the third antenna unit 4 operating in the corresponding frequency band when the electronic device 100 in some embodiments of this application is in different usage scenarios. Figure 11 It can be used as Figure 6 The diagram shows the radiation efficiency of the third antenna unit 4 of the electronic device 100, which is operated in the low-frequency band and obtained from simulation tests.

[0201] in, Figure 11 The diagram illustrates the radiation efficiency of the third antenna element 4 operating in the low-frequency band under both free space (FS) and user handheld (BHHR) scenarios.

[0202] in, Figure 11 The example also uses the low-frequency bands B5, B8, B20, and B28 as examples.

[0203] When the third antenna element 4 is in a free-space scenario where it is not being held, the B5 band, such as Figure 11 As shown in column B5(FS), the radiative efficiency is approximately -5.5 dB; the B8 band, as... Figure 11 As shown in column B8(FS), the radiative efficiency is approximately -5dB; the B20 band, as... Figure 11 As shown in the B20(FS) column, the radiative efficiency is approximately -5dB; the B28 band, as... Figure 11 As shown in column B28(FS), the radiation efficiency is approximately -7.5dB. When the third antenna element 4 is in a user-held scenario (where, Figure 11 Specifically, in the scenario where the user holds the device with their right hand (BHHR), the B5 band, such as...

Figure 11 As shown in the B28(BHHR) column, the radiation efficiency is approximately -12.5dB.

[0204] It is evident that the third antenna element 4 exhibits high radiation efficiency across all frequency bands in free-space scenarios. Furthermore, since the third antenna element 4 is located in the middle region of the side end D3, unlike the second antenna element 3, it also demonstrates high radiation efficiency under the same right-hand grip scenario.

Figure 15 As shown in the N78 (USBR) column, the radiative efficiency is approximately -12.6 dB. The radiative efficiency of the GPS L1 band is less affected and was not tested.

[0220] It can be seen that the seven-antenna unit 8 has high radiation efficiency in both the GPS L1 band and the 5G NR band in both free space and user-held scenarios.

[0232] It is evident that the tenth antenna element 11 exhibits high radiation efficiency in the 5G NR band under free-space conditions.

[0233] Therefore, it can be seen that the multiple antenna elements 200 of the electronic device 100 of this application have good radiation efficiency in their respective supported frequency bands, and can achieve good antenna performance.

[0234] Among them, such as Figure 2 , Figure 6 As shown in the figure, the electronic device 100 also includes a frame B1, and the first radiating branch 21, at least one parasitic branch 22, etc. are disposed on the frame B1 of the electronic device 100 and are spaced apart by a gap X1.

[0235] In some embodiments, the frame B1 of the electronic device 100 is a metal frame, and the first radiating branch 21, at least one parasitic branch 22, etc., are metal frame segments formed by opening the gap X1 in the metal frame of the electronic device 100.

[0236] In some other embodiments, the frame B1 of the electronic device 100 is a non-metallic frame, and the first radiating branch 21, at least one parasitic branch 22, etc., are metal segments disposed in the frame of the electronic device 100, and the first radiating branch 21, at least one parasitic branch 22, etc., are spaced apart from each other.

[0237] That is, in some other embodiments, the frame B1 of the electronic device 100 may also be a non-metallic frame with low conductivity, such as plastic, ceramic, etc. The first radiating branch 21, at least one parasitic branch 22, etc., are metal segments disposed in the frame B1 of the electronic device 100.

[0238] The first radiating branch 21, at least one parasitic branch 22, and other branches may be embedded in the frame of the electronic device 100 or disposed on the inner side of the frame of the electronic device 100.

[0239] In some embodiments, the first radiating branch 21, at least one parasitic branch 22, etc., are elongated, and the surface with the largest area of ​​the first radiating branch 21, at least one parasitic branch 22, etc., is a surface parallel to the frame surface of the frame B1, wherein the frame surface of the frame B1 is substantially perpendicular to the plane of the display screen of the electronic device 100.

[0240] like Figure 2 , Figure 6 As shown in the figures, the electronic device 100 also includes a motherboard 201, wherein the first feed source 23 and other feed sources, as well as the functional device 1, may be specifically disposed on the motherboard 201. The figures in this application are merely schematic diagrams; in some figures, due to layout issues, some feed sources are not located on the motherboard 201. The aforementioned grounding may be achieved by connecting to the ground on the motherboard 201.

[0241] Among them, such as Figure 2 , Figure 6 As shown in the figure, the electronic device 100 also includes a middle frame 202, which is used to support structures such as a display screen, and the middle frame 202 serves as the ground of the whole machine. The ground on the motherboard 201 is connected to the middle frame 202 to provide ground potential.

[0242] The aforementioned grounding can also be achieved by directly connecting to the middle frame 202.

[0243] The electronic device 100 may also include an antenna bracket, which is made of insulating material. The first radiating branch 21, at least one parasitic branch 22, etc., may also be fixed on the corresponding antenna bracket and fixed to the corresponding position of the electronic device near the frame B1 through the antenna bracket.

[0244] In some embodiments, the first radiating branch 21, at least one parasitic branch 22, etc., may be an FPC (flexible printed circuit) fixed on the antenna bracket or an LDS (Laser-Direct-structuring) metal segment formed on the antenna bracket by laser technology, or a PDS metal segment formed on the antenna bracket by PDS (Printing Direct Structure) technology (e.g., forming a metal segment by printing conductive ink, conductive silver paste, etc. on the antenna bracket), and fixed to a corresponding position in the electronic device 100 by the antenna bracket, for example, a corresponding position near the frame B1.

[0245] The electronic device 100 can be any device including an antenna, such as a mobile phone, tablet computer, smartwatch, or laptop computer. Furthermore, the electronic device 100 can be a tablet-type electronic device or a foldable electronic device. The electronic device 100 also includes other structures, such as a processor, memory, speaker, USB interface, etc., which are not relevant to the improvements in this application and will not be described in detail here.

[0246] Please see Figure 19 The diagram below shows a structural block diagram of an electronic device 100 in some embodiments of this application. In some embodiments, the electronic device 100 includes an antenna assembly 300.

[0247] In some embodiments, the antenna assembly 300 may include the aforementioned first antenna element 2.

[0248] For example, the antenna assembly 300 may include a first radiating stub 21, at least one parasitic stub 22, and a first feed 23. The first radiating stub 21 and the at least one parasitic stub 22 are spaced apart and coupled. The first radiating stub 21 includes a first feed point F1 connected to the first feed 23. Under the excitation of the first feed 23, the first radiating stub 21 supports the transmission and reception of electromagnetic wave signals in a first frequency band. The first radiating stub 21 and the at least one parasitic stub 22 cooperate to support the transmission and reception of electromagnetic wave signals in a second frequency band.

[0249] The specific structure of the antenna assembly 300 can be found in the aforementioned specific structure of the first antenna unit 2, and will not be repeated here.

[0250] In some embodiments, the antenna assembly 300 may also include the structure of other antenna elements mentioned above, such as the structure of the ninth antenna element 10, etc., as detailed above.

[0251] in, Figure 19 In the structural block diagram, it is only for the purpose of illustrating that the electronic device 100 includes an antenna assembly 300. Obviously, the electronic device 100 is the electronic device 100 in any of the foregoing embodiments, and may also include other necessary structures.

[0252] The electronic device 100 and antenna assembly 300 of this application, when the functional device 1 is close to the first radiating branch 21 of the first antenna element 2, ensure that the feeding connection of the first feed point F1 is not affected even when the functional device 1 is close to the first radiating branch 21. This is because the projection of the edge of the functional device 1 near the first radiating branch 21 onto the first radiating branch 21 is located outside the target area of ​​the first feed point F1. In other words, the area directly opposite the first radiating branch 21 and the edge of the functional device 1 near the first radiating branch 21 does not include connection points such as the first feed point F1, but only the first radiating branch 21 itself. Since the first feed point F1 is located outside the target area, the electronic device 100 of this application can position the first antenna element 2 close to the functional device 1, making full use of space. Furthermore, since the first antenna element 2 supports at least two frequency bands, it can effectively meet the requirements of multiple frequency bands within a limited space.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Where there is no conflict, the embodiments and features in the embodiments of this application can be combined with each other.
