Abstract :
In this paper, we propose a planar folded dipole antenna (PFDA). The PFDA consists of a folded loop element placed horizontally on the top of the ground plane (GP) so that the antenna has a lower profile. In the analysis, an electromagnetic simulator based on the model of moments is used. The design parameters, which are useful in practical operation, are obtained. An example of a low profile antenna is designed, based on these parameters, and antenna characteristics such as VSWR, the current distributions and the radiation patterns are shown. Furthermore, we study the miniaturization of the antenna including a GP by reducing the GP length.
