A multiband antenna comprises a ground plane, a substrate, and a radiating metal element, wherein a side of the substrate is substantially adjacent to a side of the ground plane; the radiating metal element is on a surface of the substrate. The radiating metal element comprises a radiating portion having a slit, a shorting portion having a first end electrically connected to the radiating portion and a second end electrically connected to the ground plane, and a feeding portion; the feeding portion comprises an antenna feeding point for electrically connecting to a signal source, wherein a first spacing is formed between the feeding portion and the radiating portion, and a second spacing is formed between the feeding portion and the shorting portion.
