A monopole antenna is provided. The monopole antenna comprises a ground element, a radiating element, a first inductive element and a second inductive element. The radiating element includes a feed point and the feed point divides the radiating element into the first radiating portion and the second radiating portion. The second radiating portion is connected with the first radiating portion. The first radiating portion and the second radiating portion support a first frequency band and a second frequency band, respectively. The operating frequency of the first frequency band is higher than that of the second frequency band. The first inductive element is connected between the first radiating portion and the ground element. The second inductive element is connected between the second radiating portion and the ground element.
