Abstract:
In order to achieve a convenient small antenna size, often a monopole antenna is printed on a substrate sheet and bent into the shape of a so-called inverted L or inverted F antenna. In this paper we consider the perfectly electrical conducting half-sheet configuration, which is a special case of a wedge, to derive an analytical representation for the radiation resistance of a miniaturized planar bent folded monopole antenna. This model is validated by simulations and compared to the case of a standard short monopole. Its higher radiation resistance than that of the conventional short monopole is put forward in this paper, which is due to its linear dependance on the antenna height.
