Abstract

A dual capacitively loaded planar inverted-F antenna (C-PIFA) is proposed and studied. The capacitive loading of the proposed structure reduces the resonant length from λ/4 to less than λ/6. While inheriting the attractive features of PIFAs, such as easy fabrication and low cost, the proposed design exhibits desired GSM bandwidth with high gain. This antenna could be used in mobile devices requiring less weight and high mechanical strength. The proposed structure can be implemented with very thin metal sheet, which accounts for its less weight.
