Contribution on notch antenna loaded by magneto-dielectric material

In the present paper we focus on the effect of a magneto-dielectric material on a notch antenna. Initially introduced for notch miniaturization, the new material loading provides some insight into the notch operating mode. The first section evokes the classical approach of notch working. Then we present the characteristics of the specific employed material, the simulation results dealing with electric and magnetic energy densities and the optimization of material size and emplacement. Finally measurements are carried out to confirm the influence of the loading material technique and to estimate the miniaturized antenna performances.
