In a broadband printed dipole antenna for wireless applications, metal plates of a radiation portion, a feed-in portion and a bandwidth modulation portion are formed on a substrate. Two radiation portions come with a specific shape and have an interval between the two radiation portions. The feed-in portion is composed of two separated long bars and coupled to one of the specific shaped radiation portions. The bandwidth modulation portion is disposed symmetrically adjacent to the feed-in portion, such that the impedance matching can be adjusted to form a broadband dipole antenna for WiMAX applications.
