Monopole Antenna Miniaturization with Magneto-Dielectric Material Loading Combined with Metal Parasitic Element

In this paper is shown a new way to use Magneto-Dielectric Materials (MDM) in order miniaturize monopole antennas. It proposed load an antenna with MDM the relative permeability achieve first 17% miniaturization rate. Then, better miniaturization, it add metal parasitic plates on both sides of material permittivity ensure capacitance useful shift antenna’s resonant frequency. By combining loading, metallic plates’ capacitances and matching circuit designed real frequency technic, from 350 MHz 200 achieved corresponding 43% height reduction. A has been match at −5 dB. The obtained bandwidth 15% (185–215 MHz) realized gain over −2.5 dBi.
