Abstract :
In this paper, we present the design of a printed multiple antenna system that uses a ferrimagnetic compound (YIG) as part of the substrate. We investigate the influence of this material on the mutual coupling between the antenna elements when an external magnetic field is applied. It is proved that the proper application of the magnetic field changes the polarization of the elements from linear to circular and additionally reduces their mutual coupling.
