For example, the front extension 20 may be an elongated extension, and the front extension 20 has a ground pad (not numbered) adjacent to the conductive through structure 4. In addition, each first front radiator 21 has a first front bending portion 211, and each first front radiator 21 has a first front recess 2100 disposed on the first front bending portion 211 and facing the front extension 20. However, the above-mentioned example is only one possible embodiment and is not intended to limit the present invention.

Further, as shown in fig. 2, the rear antenna structure 3 is disposed on a rear surface of the antenna carrier substrate 1, and the conductive through structure 4 penetrates the antenna carrier substrate 1 and is electrically connected to the rear antenna structure 3.

For example, the conductive through structure 4 has a feed pad (not numbered) adjacent to the front extension 20, and the back extension 30 may be a strip extension. In addition, each first back radiator 31 has a first back bending portion 311, and each first back radiator 31 has a first back recess 3100 disposed on the first back bending portion 311 and facing the back extension 30.

Furthermore, the two second front radiators 22 and the two second back radiators 32 may cooperate with each other to form a dual-frequency dipole antenna, and the dual-frequency dipole antenna may be configured to provide operating frequencies of 2GHz and 5GHz simultaneously.

Thereby, the two first front radiators 21 and the two first back radiators 31 may cooperate with each other to form a single-frequency dipole antenna, and the single-frequency dipole antenna may be configured to provide an operating frequency of 5 GHz. However, the above-mentioned example is only one possible embodiment and is not intended to limit the present invention.

It should be noted that, in each of the second front radiators 22, the length of the second front left short bending portion 221 (for example, the length in the horizontal direction or the length extending from one of the end portions of the front extension section 20) is smaller than the length of the second front left long bending portion 222 (for example, the length in the horizontal direction or the length extending from one of the end portions of the back extension section 30), and the length of the second front right short bending portion 223 (for example, the length in the horizontal direction or the length extending from one of the end portions of the front extension section 20) is smaller than the length of the second front right long bending portion 224 (for example, the length in the horizontal direction or the length extending from one of the end portions of the front extension section 20). Furthermore, in each second front radiator 22, the area of the second front left short bending portion 221 (e.g., the area extending from one of the end portions of the back extension 30) is smaller than the area of the second front left long bending portion 222 (e.g., the area extending from one of the end portions of the back extension 30), and the area of the second front right short bending portion 223 (e.g., the area extending from one of the end portions of the back extension 30) is smaller than the area of the second front right long bending portion 224 (e.g., the area extending from one of the end portions of the back extension 30). Further, the second front left short folded portion 221 and the second front right short folded portion 223 may be symmetrically disposed with each other, and the second front left long folded portion 222 and the second front right long folded portion 224 may be symmetrically disposed with each other. However, the above-mentioned example is only one possible embodiment and is not intended to limit the present invention.

For example, in conjunction with fig. 1 to 3, each second back radiator 32 has a second back left short bent portion 321, a second back left long bent portion 322, a second back right short bent portion 323, and a second back right long bent portion 324, and each second back radiator 32 has a plurality of second back left recessed areas 3201 and a plurality of second back right recessed areas 3202 respectively facing the plurality of second back left recessed areas 3201. It should be noted that in each second back radiator 32, the length of the second back left short bending portion 321 (e.g., the length in the horizontal direction or the length extending from one of the end portions of the back extension 30) is smaller than the length of the second back left long bending portion 322 (e.g., the length in the horizontal direction or the length extending from one of the end portions of the back extension 30), and the length of the second back right short bending portion 323 (e.g., the length in the horizontal direction or the length extending from one of the end portions of the back extension 30) is smaller than the length of the second back right long bending portion 324 (e.g., the length in the horizontal direction or the length extending from one of the end portions of the back extension 30). Furthermore, in each second back radiator 32, the area of the second back left short bending portion 321 (e.g., the area extending from one of the end portions of the back extension 30) is smaller than the area of the second back left long bending portion 322 (e.g., the area extending from one of the end portions of the back extension 30), and the area of the second back right short bending portion 323 (e.g., the area extending from one of the end portions of the back extension 30) is smaller than the area of the second back right long bending portion 324 (e.g., the area extending from one of the end portions of the back extension 30). Further, the second back left short folded portion 321 and the second back right short folded portion 323 may be symmetrically disposed, and the second back left long folded portion 322 and the second back right long folded portion 324 may be symmetrically disposed. However, the above-mentioned example is only one possible embodiment and is not intended to limit the present invention.

For example, as shown in fig. 3, a second front radiator 22 and a second back radiator 32 are connected to a first end portion 2003 of the front extension 20 and a first end portion 3003 of the back extension 30, respectively, and the "outline (or contour) of the second front radiator 22 connected to the first end portion 2003 of the front extension 20" and the "outline (or contour) of the second back radiator 32 connected to the first end portion 3003 of the back extension 30" may be symmetrical to each other. Furthermore, another second front radiator 22 and another second back radiator 32 are connected to a second end portion 2004 of the front extension 20 and a second end portion 3004 of the back extension 30, respectively, and the "outline (or contour) of the second front radiator 22 connected to the second end portion 2004 of the front extension 20" and the "outline (or contour) of the second back radiator 32 connected to the second end portion 3004 of the back extension 30" may be symmetrical to each other. However, the above-mentioned example is only one possible embodiment and is not intended to limit the present invention.

Thus, as shown in fig. 3, the "second front left short bending portion 221 and the second front right short bending portion 223" of each second front radiator 22 and the "second back left short bending portion 321 and the second back right short bending portion 323" of each second back radiator 32 may be matched with each other (for example, the adjacent second front radiator 22 and the second back radiator 32 may be matched with each other) to provide an operating frequency of 2 GHz. Furthermore, the "second front left long-bending portion 222 and the second front right long-bending portion 224" of each second front radiator 22 and the "second back left long-bending portion 322 and the second back right long-bending portion 324" of each second back radiator 32 may cooperate with each other to provide an operating frequency of 5 GHz.
