Abstract
An antenna having a parasitic element is disclosed, the antenna including a ground, a radiation unit which is arranged on a different area of the same plane as the ground, and a parasitic element which is selectively connected to the ground, and operates as an antenna element. Where the antenna is in a first mode, electromagnetic waves resonate in the radiation unit, and where the antenna is in a second mode, electromagnetic waves resonate in the radiation unit and the parasitic element.
