Optimization of the use of magneto-dielectric materials for highly miniaturized monopole antennas

International audienceThis article presents the miniaturization of a UWB planar monopole antenna covering the VHF band through the use of low loss Magneto-Dielectric Materials (MDM). By using slots in the antenna structure, the dimensions and position of the MDM have been optimized to reduce the amount of MDM required to obtain an optimum miniaturization rate. This new monopole structure shows a miniaturization rate of 60% by covering about only 5% of the antenna surface area
