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.
