The embodiments described herein are only used to more clearly illustrate the technical solutions of this application and are therefore only examples and are not intended to limit the scope of protection of this application.

[0027] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more features.

[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0029] The embodiment of the present application provides an antenna structure and a mobile device to solve the problem that when the antenna power is increased, the SIM card in the SIM card holder 3 may be interfered with or even fail.

[0030] See also Figure 1 and Figure 2 An antenna structure includes an antenna body 1, a shielding component 2 and a SIM card holder 3. The antenna body 1 is arranged on one side of the shielding component 2, and the SIM card holder 3 is arranged on the side of the shielding component 2 away from the antenna body 1. The shielding component 2 is grounded, and the shielding component 2 is arranged opposite to the SIM card holder 3. At least part of the antenna body 1 is arranged opposite to the SIM card holder 3.

[0031] By arranging a shielding member 2 between the SIM card holder 3 and a section of the antenna body 1 facing the SIM card holder 3, the impact of the antenna body 1 on the SIM card holder 3 when the power is increased can be reduced, thereby reducing interference with the SIM card when a SIM card is installed in the SIM card holder 3. In addition, by grounding the shielding member 2, the shielding performance of the shielding member 2 can be further improved, thereby solving the problem that the SIM card in the SIM card holder 3 will be interfered with or even fail when the antenna power is increased.

[0032] See also Figure 2 and Figure 4 The antenna structure further includes a fixing bracket 4 and a PCB board 5. The fixing bracket 4 is disposed on one side of the PCB board 5 in the first direction. The SIM card holder 3 is fixedly connected to the side of the PCB board 5 near the fixing bracket 4. The antenna body 1 is fixedly connected to the side of the fixing bracket 4 away from the PCB board 5. The shielding member 2 is fixedly connected to the side of the fixing bracket 4 near the PCB board 5. In this embodiment, the shielding member 2 is formed on the fixing bracket 4 by laser direct forming. In other embodiments of the present application, the shielding member 2 is any one of a solid copper FPC board, a layer of conductive cloth, or a layer of copper foil.

[0033] See also Figure 3 The antenna body 1 includes a first antenna body 11, a second antenna body 12 and a third antenna body 13 connected in sequence. The first antenna body 11 is located at the edge of one end of the fixing bracket 4 in the second direction, the second antenna body 12 is located at the edge of one end of the fixing bracket 4 in the third direction, and the third antenna body 13 is located at the edge of the other end of the fixing bracket 4 in the second direction.

[0034] In this embodiment, the first direction is the thickness direction of the PCB board 5 , the second direction is the length direction of the fixing bracket 4 , and the third direction is the width direction of the fixing bracket 4 .

[0035] See also Figure 2 and Figure 4 The SIM card holder 3 is located at one end of the PCB board 5 in the first direction. The projected area of the shielding component 2 on the PCB board 5 is larger than the projected area of the SIM card holder 3 on the PCB board 5. The shielding component 2 and the SIM card holder 3 are directly opposite each other, and the first antenna body 11 and the SIM card holder 3 are directly opposite each other. This allows the shielding component 2 to reduce the impact of the first antenna body 11 on the SIM card holder 3 when the first antenna body 11 is in a high-power state. In addition, the height difference between the shielding component 2 and the first antenna body 11 in the first direction is H, 1.6mm≤H≤2mm. When H is less than 1.6mm, the shielding component 2 is too close to the first antenna body 11, resulting in a greater impact of the shielding component 2 on the first antenna body 11. When H is greater than 2mm, the thickness of the mobile device is too large.

[0036] See also Figure 1and Figure 2 In order to reduce the impact of the second antenna body 12 and the third antenna body 13 on the SIM card holder 3, the second antenna body 12 is spaced apart from the SIM card holder 3 in the first direction and staggered in the second direction, and the third antenna body 13 is spaced apart from the SIM card holder 3 in the first direction and staggered in the third direction.

[0037] The fixing bracket 4 defines a fixed cavity, which houses an electrical component. In this embodiment, the electrical component is a speaker. Providing a sound cavity in the fixing bracket 4 not only reduces space usage but also improves the speaker's audio performance by providing a larger cavity. The speaker is spaced apart from the antenna body 1 in the first direction and offset in the second and third directions. The offset distance L1 in the second direction reduces interference with the antenna body 1. The offset distance L2 in the third direction is 3mm≤L1≤4mm, and 3mm≤L2≤4mm.

[0038] See also Figure 2 and Figure 4 , an antenna shrapnel 51, a grounding shrapnel, a shield, an RF feeder, and a grounding wire are provided on the PCB board 5. In this embodiment, the housing of the SIM card holder 3 is made of metal, and the SIM card holder 3 is connected to the grounding wire, thereby improving the anti-interference capability of the SIM card holder 3 itself. The shielding component 2 is connected to the grounding shrapnel, which is connected to the shield, which is connected to the grounding wire, thereby improving the shielding performance of the shielding component 2. In this embodiment, the shield is a 100nh inductor or a 0ohm resistor. The antenna shrapnel 51 is provided on the side of the SIM card holder 3 away from the antenna shrapnel 51 to reduce the interference of the antenna shrapnel 51 on the SIM card holder 3. The antenna shrapnel 51 is connected to the RF feeder and the antenna body 1 to facilitate the connection of the antenna to the communication module in the mobile device.

[0039] The present application also provides a mobile device including the antenna structure described above. Since the mobile device includes the antenna structure described above, and because it has at least some or all of the beneficial effects of the antenna structure described above, they will not be described in detail here.
