PLANAR INVERTED F ANTENNA

摘要

A planar inverted F antenna is provided to reduce size of antenna by installing auxiliary plate between ground surface and antenna body. A planar inverted F antenna(100) comprises a ground surface(110), an antenna body(120), a power feeding line(130), a ground pin(140), and at least one or more auxiliary plate(150). The ground surface has a finite plane, and is formed with a conductive material. The antenna body maintains a constant interval from the ground surface, and transmits/receives an electric wave. The power feeding line electrically connects the ground surface and the antenna body, and is vertically formed about the ground surface. The ground pin grounds the antenna body on the ground surface. At least one or more auxiliary plate is positioned between the antenna body and the ground surface. A width(w) of the auxiliary plate is smaller than a width(W) of the antenna body. The auxiliary plate has T shape.
