[0027] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0028] Figure 1 This is a schematic diagram illustrating an antenna structure according to an exemplary embodiment. For example... Figure 1As shown, the antenna structure includes a first radiator 1, an antenna support 2, and a second radiator 3. The first radiator 1 is a frame radiator; for example, it can be a portion of the external frame of the electronic device. The antenna support 2 and the second radiator 3 can be disposed inside the electronic device. The second radiator 3 is mounted on the antenna support 2 and fixed thereto. For example, the second radiator 3 can be disposed on any surface of the antenna support 2. Specifically, it can be disposed on the surface of the antenna support 2 facing the first radiator 1 to increase the coupling area between the second radiator 3 and the first radiator 1; or it can be disposed on other surfaces intersecting with the surface of the antenna support 2 facing the first radiator 1. Alternatively, the second radiator 3 can be disposed inside the antenna support 2. The specific design can be customized as needed, and this disclosure does not impose any limitations on this.

[0029] The antenna support 2 can be an insulating support, such as a plastic support, a rubber support, or a support structure made of other insulating materials. The second radiator 3 can be a metal patch, such as copper foil or aluminum foil. The second radiator 3 can be a radiator of any shape. For example, the second radiator 3 can be a ring radiator, which helps to increase the coupling area between the second radiator 3 and the first radiator 1; as another example, the second radiator 3 can be a radiator with curved wiring; and as yet another example, the second radiator 3 can be a polygonal structure.

[0030] In addition to arranging the second radiator 3, other electronic components or mechanical structures can also be arranged on the same antenna support 2, and this disclosure does not impose any limitations on this. For example, in some embodiments, the antenna support 2 includes a circuit board substrate, and the second radiator 3 includes metal traces, such as copper foil traces. Other electronic components of the associated electronic device and shielding covers can also be arranged on the circuit board substrate. In other embodiments, the second radiator 3 can be an LDS (Laser-Direct-structuring) antenna. Specifically, the antenna support 2 and the second radiator 3 can be adaptively designed as needed, and this disclosure does not impose any limitations on this.

[0031] In this embodiment, the second radiator 3 and the first radiator 1 can cover at least one of the same frequency bands. For example, the antenna structure also includes a first feed 4 and a second feed 5. The first feed 4 is electrically connected to the first radiator 1, and the second feed 5 is electrically connected to the second radiator 3. The resonance generated by the first feed 4 to excite the first radiator 1 covers the N78 frequency band. Similarly, the resonance generated by the second feed 5 to excite the second radiator 3 can also cover the N78 frequency band, thus achieving coverage of the same frequency band by the second radiator 3 and the first radiator 1. Furthermore, there is current coupling between the second radiator 3 and the first radiator 1, meaning that the current on the second radiator 3 can be slot-coupled to the first radiator 1, and the current on the first radiator 1 can also be slot-coupled to the second radiator 3. This helps to balance the current intensity on the first radiator 1 and the second radiator 3, ensuring the radiation performance of the antenna structure. At the same time, the antenna energy is carried by the first radiator 1 and the second radiator 3, thereby reducing the SAR values ​​of the first radiator 1 and the second radiator 3, which helps to reduce the radiation impact of the antenna structure and improve radiation safety.

[0032] The above description only illustrates the current coupling between the first radiator 1 and the second radiator 3 when both cover the N78 frequency band. In other embodiments, the first radiator 1 and the second radiator 3 may also be radiating one or more of the N78, N77, and N48 frequency bands, and this disclosure does not impose any limitations on this. The above description uses the example of the first radiator 1 and the second radiator 3 being connected to their respective feeders. In other embodiments, only the first radiator 1 may be connected to the feeder, and the second radiator 3 may act as a parasitic stub coupled to the first radiator 1, thereby sharing the current and antenna energy.

[0033] In some embodiments, such as Figure 2 As shown, the second radiator 3 includes a first branch 31, a second branch 32, and a third branch 33. The second branch 32 and the third branch 33 are respectively connected to the two ends of the first branch 31 one by one, and the second branch 32 and the third branch 33 are connected to the same side of the first branch 31. The second branch 32 and the first branch 31 form an angle of about 90°, and the third branch 33 and the first branch 31 form an angle of about 90°, thus constructing a ring-shaped second radiator 3. Constructing a ring-shaped second radiator 3 is beneficial to the uniform distribution of current between the second radiator 3 and the first radiator 1.

[0034] Furthermore, the second radiator 3 also includes a fourth branch 34 and a fifth branch 35. The fourth branch 34 is connected to the first branch 31, and its extension direction is parallel to that of the first branch 31. The fourth branch 34 is positioned close to the second branch 32. Similarly, the fifth branch 35 is connected to the first branch 31, and its extension direction is parallel to that of the first branch 31. The fifth branch 35 is positioned close to the third branch 33, and the fourth branch 34 and the fifth branch 35 extend in opposite directions. This arrangement of the fourth branch 34 and the fifth branch 35 increases the area of ​​the second radiator 3, which is beneficial for uniform coupling between the second radiator 3 and the first radiator 1.

[0035] The fourth branch 34 and the fifth branch 35 can be arranged symmetrically or asymmetrically. The widths of the fourth branch 34 and the fifth branch 35 can be equal or unequal. The width of the fourth branch 34 can be equal or unequal to the width of the first branch 31, and the width of the fifth branch 35 can be equal or unequal to the width of the first branch 31. This disclosure does not impose any restrictions on this.

[0036] In some embodiments, the fifth branch 35 and the third branch 33 are disposed close to the first radiator 1 relative to the fourth branch 34 and the second branch 32. The end of the first radiator 1 may be located within the opening area enclosed by the third branch 33, the first branch 31, and the fifth branch 35, or outside the opening area. In the extending direction of the first radiator 1, that is... Figure 3 In the vertical direction shown, the end of the first radiator 1 extends beyond the end of the fifth branch 35, and the distance between the end of the first radiator 1 and the third branch 33 is greater than or equal to 1 mm and less than or equal to 4 mm, that is... Figure 3 As shown, 1mm≤L1≤4mm, for example, L1 is equal to 2mm, 2.55mm, 3.02mm, 3.54mm or 3.9mm.

[0037] In the direction perpendicular to the extension direction of the first radiator 1, that is... Figure 3 In the left-right direction shown, the distance between the fifth branch 35 and the first radiator 1 is greater than or equal to 2 mm and less than or equal to 6 mm. That is... Figure 3 As shown, 2mm≤L2≤6mm, for example, L1 is equal to 2.55mm, 3mm, 3.84mm, 4.55mm, 5mm or 5.6mm.

[0038] Based on the technical solution of this disclosure, an electronic device is also provided, which may include the antenna structure described in any of the foregoing embodiments. The antenna support 2 and the second radiator 3 may be disposed inside the electronic device. For example, the antenna support 2 may be fixed to the middle frame of the electronic device, and the first radiator 1 may form part of the outer frame segment of the electronic device, such as part of the top frame segment, part of the bottom frame segment, or part of the side frame segment. This disclosure does not impose any limitations on this.
