The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] The utility model embodiment provides an antenna structure used in a housing, such as Figure 1 and Figure 3 As shown, the antenna structure includes a metal sputtering layer 2, a conductive foam 3 and an antenna body 4. The metal sputtering layer 2 is disposed on the inner wall of the housing 1, and the conductive foam 3 is disposed on the metal sputtering layer 2.

[0031] The antenna body 4 includes a baffle portion 41, a radiating portion 42, and a bending portion 43 for connecting the baffle portion 41 and the radiating portion 42. A feeding point (not shown) is provided on the radiating portion 42, through which a signal is input to the antenna body 4 and radiated out through the radiating portion 42.

[0032] The bent portion 43 of the antenna body 4 is in contact with the conductive foam 3 , so that the antenna body 4 , the conductive foam 3 and the metal sputtering layer 2 form a complete antenna structure.

[0033] The antenna body 4 of this embodiment is fixed in the housing 1 through a connecting rib plate 44 formed by bending the retaining wall portion 41 , so as to ensure that the bent portion 43 can maintain contact with the conductive foam 3 .

[0034] The antenna structure cleverly utilizes the metal sputtering layer 2 on the inner wall of the casing 1 and the conductive foam 3 attached to the metal sputtering layer 2, and forms a complete antenna structure through the antenna body 4 in contact with the conductive foam 3, eliminating the traditional antenna's built-in reference ground (copper foil or aluminum foil), simplifying the antenna design, and reducing costs and increasing efficiency.

[0035] like Figure 2As shown, the housing 1 of this embodiment can be a shell of the electronic device system end, and the shell can be an upper cover or a bottom shell, and the upper cover or the bottom shell includes a main body 10 and a skirt portion 11 located around the main body 10, wherein the angle between the skirt portion 11 and the main body 10 is greater than or equal to 90 degrees. When the electronic device is placed on the operating platform, the main body 10 is used to contact the table top of the operating platform, and there is an angle between the skirt portion 11 and the table top, so that it is convenient for the user to pick up the electronic device.

[0036] Furthermore, the metal sputtering layer 2 of the present embodiment is laid on the inner wall surface of the main body 10, the bending portion 43 and the radiation portion 42 are respectively attached to the inner wall surface of the skirt portion 11, and the radiation portion 42 extends along the inner wall surface direction of the skirt portion 11. In this way, the area of ​​the radiation portion 42 can be maximized while ensuring that space inside the casing 1 is saved.

[0037] As for the specific degree of the angle between the skirt portion 11 and the main body portion 10 of this embodiment, there is no specific limitation and it can be determined according to the shape of the housing 1.

[0038] like Figure 3 As shown, the metal sputtering layer 2 is mainly laid on the inner wall surface of the main body 10 of the casing 1 and has a portion extending to the inner wall surface of the skirt portion 11. The conductive foam 3 of this embodiment is arranged on the metal sputtering layer 2 and the portion extending to the skirt portion 11, so as to facilitate the bending portion 43 and the radiation portion 42 to be respectively fitted with the inner wall surface of the skirt portion 11.

[0039] Preferably, the conductive foam 3 of this embodiment is attached to the metal sputtering layer 2 and has a portion extending beyond the metal sputtering layer 2. The portion of the conductive foam 3 extending beyond the metal sputtering layer 2 can be used to solve sputtering process problems and avoid the phenomenon that causes unstable antenna performance.

[0043] The method of fixing the reinforcing plate 46 between the retaining wall portion 41 and the radiation portion 42 is not limited. Figure 5 As shown, in some embodiments, the reinforcing plate 46 can be stuck between the retaining wall portion 41 and the radiating portion 42 and abut against the retaining wall portion 41 and the radiating portion 42 respectively to limit the retaining wall portion 41 and the radiating portion 42 from approaching each other.

[0044] Specifically, slots may be machined on the retaining wall portion 41 and the radiating portion 42 respectively, and then a clamping block may be machined on the reinforcing plate 46 , and the reinforcing plate 46 may be fixed between the retaining wall portion 41 and the radiating portion 42 by clamping the clamping block in the slot.

[0045] In this embodiment, both the retaining wall portion 41 and the radiating portion 42 are sheet structures. The radiating portion 42 is attached to the inner wall surface of the skirt portion 11 of the housing and extends along the inner wall surface of the skirt portion 11 .

[0046] The radiation portion 42 is provided with a plurality of radiation branches, and the shapes, structures or layouts of the plurality of radiation branches are not specifically limited and can be determined according to parameters such as the frequency of the transmitted signal.
