Miniaturization strategy of compact antenna using magneto-dielectric material

This article describes a strategy of miniaturization for an electrically small Monopolar Wire-Plate Antenna (MWPA) loaded by Magneto-Dielectric Material (MDM). The multiplication of antenna's shorted wires lead to a stronger interaction with the material. An electrically small six wires MWPA loaded with MDM is designed at VHF band (sphere radius around λ
₀
/15). While conserving interesting performances (η
_t
=70%), the designed antenna is 27% smaller than a single shorted MWPA without loading material.
