Abstract

An antenna is provided comprising a transmission element, a ground element, a first parasitic element, a second parasitic element and a third parasitic element. The transmission element is located on a first plane, wherein the transmission element is T shaped, and comprises a first transmission portion and a second transmission portion and the second transmission portion is perpendicular to the first transmission portion and connected to an end thereof. The ground element is located on a second plane parallel to the first plane. The first parasitic element, the second parasitic element and the third parasitic element are connected to the ground element and located on the second plane.
