An antenna having a capacitive element is disclosed. Herein, the antenna is configured of a radiator, a ground plane being spaced apart to a predetermined distance from the radiator, a ground pin electrically connected to the radiator and the ground plane, a capacitive element located between the radiator and the ground plane, a first branch arm electrically connecting the capacitive element and the radiator, and a second branch arm electrically connecting the capacitive element and the ground plane. Thus, multiple band and broad band characteristics can be realized by the simple structure of the antenna.
