Frequency Reconfigurable Miniature Monopole Antenna Using Magneto-Dielectric Material

This paper presents a reconfigurable miniature monopole antenna partially loaded with a Tunable Magneto-Dielectric Material (T-MDM) in the VHF band. A parametric study optimised the amount of the T-MDM and its effect on miniaturization. The antenna achieves a 40% miniaturization rate with just 17% of its height loaded by a 2 mm thick MDM, and demonstrates 15% frequency agility in the VHF band.
