Electrically Small Microstrip Antenna Based on Magnetodielectric Materials

Abstract

An electrically small microstrip patch antenna based on high permittivity dielectric and magnetodielectric materials (MDM) is investigated in this paper. The basic parameters of microstrip patch antennas based on high dielectric and magnetodielectric materials are compared with other solutions. The analysis shows that an MDM-based patch surface is 7.14 times smaller when compared with a suspended plate antenna. The use of MDM improves bandwidth and offers perfect impedance matching between the material and free space, over a much wider bandwidth.
