摘要：
A planar antenna includes a ground plane having a ground point. A main radiating element has a feeding point positioned adjacent to the ground point. The main radiating element is positioned adjacent to a contact side of the ground plane such that a space is formed there between. A parasitic element is positioned adjacent to the contact side such that a space is formed there between. The main radiating element has a shape such that the space between the main radiating element and the contact side becomes larger as the main radiating element becomes closer to the parasitic element and the parasitic element has a shape such that the space between the parasitic element and the contact side becomes larger as the parasitic element becomes closer to the main radiating element. Additionally, the parasitic element may have a slit formed therein.
