Multiferroic heterostructures consisting of a piezoelectric or ferroelectric material and a ferromagnetic material with magnetostrictive properties allow for cross coupling of the electric and magnetic degrees of freedom via strain mediation of the magnetoelectric coupling. This phenomenon is usually studied in the long wavelength approximation of electrostatic/magnetostatic limit. In the dynamic regime where electromagnetic fields are coupled, the magnetoelectric effect of multiferroic materials or nanostructures has been usually considered only under the concept electrically shifting the ferromagnetic resonance for phase shifters in the current literature. In this work we investigate the feasibility of a new concept design of multiferroics to be used directly as an antenna “surface” material or transmitting/receiving element. This fundamentally new approach based on multiferroics as antenna element in the UHF band, promises a reduction of the antenna size up to
