We have proposed an open terminated folded inverted-L antenna (FILA) with slits. In order to miniaturize the FILA, several slits are employed on the substrate surface. Folded structure is used for broadbanding. Design of the FILA to achieve broadband

We have investigated a folded inverted-L antenna (FILA) and introduced equations with respect to the limitation of the theoretical bandwidth. The miniaturization of the conventional FILA was not sufficient because the FILA consists of a substrate per
