Abstract

In this paper, we present a patch antenna design and fabrication that uses a ferrimagnetic compound, Yttrium Iron Garnet (YIG), as part of its substrate. It is proved via both numerical simulations and experimental measurements, that with suitable application of an external magnetic field, a reconfigurable behavior in terms of the polarization characteristics can be achieved. The antenna is reconfigured from a single band linear polarized to a dual band circular polarized one, with different polarization sense in each resonance band. Mixtures containing YIG and epoxy resin in various consistencies have been examined.
