Abstract: An antenna system is provided, including a ground plane, a first antenna unit, a second antenna unit, a first ground unit and a second ground unit. The ground plane includes a first side and a second side. The first ground unit and the ground plane jointly form a first closed loop, and a length of the first ground unit matches the first high-frequency signal and the second high-frequency signal to provide grounding of the high-frequency signals. The second ground unit forms a second closed loop and is connected to the first ground unit, and a length of the second ground unit is greater than the length of the first ground unit. A sum of the length of the second ground unit and the length of the first ground unit matches the first low-frequency signal and the second low-frequency signal, to jointly provide the grounding of the low-frequency signals.

Abstract: 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.
