The third side surface 105 and the fourth side surface 106 can be connected between the upper surface 101 and the lower surface 102 and opposite to each other (or can be arranged in reverse to each other). For example, the antenna-carrying substrate 1 can have a rectangular shape, a similar rectangular shape, or any possible shape. The antenna-carrying substrate 1 can be any kind of insulating material or high dielectric material (e.g., ceramic or ceramic-like material). However, the above-mentioned example is only one possible embodiment and is not intended to limit the present application.

[0030] Further, the first antenna structure 2 and the second antenna structure 3 can be arranged on the upper surface 101 and the lower surface 102 of the antenna-carrying substrate 1.

However, the above example is only one embodiment and is not intended to limit the present application.

[0033] For example, as shown in FIG. 1, the first antenna structure 2 can include a first radiating layer 21, and the second antenna structure 3 can include a second radiating layer 31. Figure 2 As shown, in one embodiment, the upper surface 101 of the antenna-carrying substrate 1 can have a continuous meandering region 1010, and the continuous meandering region 1010 can be located between the first antenna structure 2 and the second antenna structure 3.

In addition, the upper surface 101 of the antenna-carrying substrate 1 can have a second separation region 1012 connected to a second end of the continuous meandering region 1010, and the second separation region 1012 can be located between the second extension portion 312 and the third side surface 105 and between the second bending portion 313 and the third side surface 105, thereby separating (separating) the second extension portion 312 and the second bending portion 313 of the second radiating layer 31 from the third side surface 105 by a second predetermined distance. However, the above example is only one embodiment and is not intended to limit the present application.

[0034] For example, as shown in FIG. 1, the first antenna structure 2 can include a first radiating layer 21, and the second antenna structure 3 can include a second radiating layer 31.
