Abstract
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.
Claims6
A wideband printed dipole antenna for wireless applications, with a substrate comprising:
- a radiation portion, including a first radiator and a second radiator arranged with an interval in between, and the first and second radiators being oval metal plates;
- a feed-in portion, having corresponding upper and lower sides in a long bar shape, and including a first linear section and a second linear section, and the first linear section being extended from the first radiator towards the second radiator, and the second linear section being extended from the second radiator towards the first radiator, and an interval being formed between the first and second linear sections;
- and
- a bandwidth modulation portion, including a first modulation metal plate and a second modulation metal plate, symmetrically disposed at the upper and lower sides of the feed-in portion.
