A multi-band antenna includes a radiating antenna member, a first parasitic antenna member, and a second parasitic antenna member. The radiating antenna member includes a feeding unit, a high frequency (HF) radiating unit and a low frequency (LF) radiating unit, the HF radiating unit and the LF radiating unit extend from the feeding unit. The first parasitic antenna member includes an HF grounding part, and an HF parasitic unit extending from the HF grounding part and adjacent to the HF radiating unit. The second parasitic antenna member includes an LF grounding part, and an LF parasitic unit extending from the LF grounding part and electromagnetically coupled to the LF radiating unit. The feeding unit is arranged between the HF grounding part and the LF grounding part; the feeding unit and the HF radiating unit define a receiving slot, and the HF parasitic unit is arranged in the receiving slot.
