Abstract

In this paper, we present the design, fabrication and characterization measurements of a proximity-coupled fed patch antenna that uses a ferrimagnetic compound, Yttrium Iron Garnet (YIG), as part of its substrate. External magnetic field is applied in order to achieve reconfigurability. Specifically, by applying a suitable external magnetic field, the linearly polarized single-band antenna exhibits dual-band behavior. Furthermore, it is proved via simulation and experimental measurements that we can achieve antenna polarization reconfigurability.
