| Zusammenfassung: | A communication device includes a ground plane and an antenna element. The antenna element includes a first radiation portion and a second radiation portion. The first radiation portion includes a meander section and a rectangular metal section. The meander section has a rectangular hook-shaped structure. A feed point is disposed at a first end of the meander section, and a second end of the meander section is electrically connected to the rectangular metal section. A first end of the second radiation portion of an L-shaped structure is electrically connected to the ground plane. A first end of the rectangular metal section is spaced apart from a second end of the second radiation portion by a first parallel slot. The communication device operates in a first frequency band with the first radiation portion and the second radiation portion, and operates in a second frequency band with the first radiation portion. |
