Abstract: The invention provides an antenna for wireless devices which improves matching of the main antenna element and parasitic antenna element in the antenna. The antenna of the invention comprises a main antenna element and a parasitic antenna element, the main antenna element and the parasitic antenna element being separated from each other, a matching element is connected between the main antenna element and the parasitic antenna element, with an end of the matching element being electrically connected to a conductor strip of the main antenna element, and the other end being electrically connected to a conductor strip of the parasitic antenna element. Optimized antenna performance can be achieved by adjusting position and value of the matching element.
