Zusammenfassung:In this paper we investigate the use of an epoxy bonded ferrimagnetic compound, Yttrium Iron Garnet (YIG), as a substrate of a patch antenna operating in Ku band. We investigate its influence on the antenna's polarization properties under the application of an external magnetic field. It is proved that the axial ratio and also the sense and the tilt of the antenna polarization ellipse are influenced by this substrate since they change in respect to the direction and the magnitude of an externally applied magnetic field. Also the presence of this material causes non reciprocal properties in the antenna operation, changing the antenna properties while in receiving or transmitting mode.
