Abstract
Disclosed is a planar inverted-F antenna with an extended grounding plane. The planar inverted-F antenna has a grounding metal plate having a selected side edge on which the extended grounding plane is formed and has a predetermined height. At least one antenna signal radiating plate is connected to the grounding metal plate by a short-circuit piece and is substantially parallel to and spaced from the grounding metal plate by a distance. A feeding point extends from the antenna signal radiating plate in a direction toward the grounding metal plate and corresponds to the extended grounding plane with a predetermined gap therebetween. With the arrangement of the extended grounding plane, the impedance matching of the antenna is improved and the impedance bandwidth of the antenna is increased.
