A multiferroic antenna apparatus and method are described which provides increased energy efficiencies and ease of implementation. Magnetoelastic and/or magnetostrictive resonator are coupled to a piezoelectric substrate, along with electrodes coupled to its opposing surfaces. In receive mode the resonators create mechanical waves in response to being excited into magnetic oscillation by receiving electromagnetic radiation, and these mechanical waves coupled to the piezoelectric substrate causing it to generate an electrical output signal at said electrodes. In transmit mode an electrical signal coupled through the electrodes induces mechanical waves in the piezoelectric substrate directed to the resonators which are excited into magnetic oscillation to output electromagnetic waves.
