CPC H01Q 21/067 (2013.01) [H01Q 3/44 (2013.01)] | 16 Claims |
1. A multiferroic radio frequency antenna apparatus, comprising:
a piezoelectric substrate;
at least one pair of electrodes coupled to said piezoelectric substrate; and
a plurality of magnetoelastic and/or magnetostrictive resonators coupled to said piezoelectric substrate;
wherein said electrodes in combination with piezoelectric substrate convert between radio frequency electrical signals input at the electrodes to mechanical waves in the piezoelectric substrate, or from mechanical waves in the piezoelectric substrate to radio frequency electrical signal from the electrodes;
wherein said magnetoelastic and/or magnetostrictive resonators in combination with said piezoelectric substrate convert between radio frequency electromagnetic waves input at said magnetoelastic and/or magnetostrictive resonators to mechanical waves in said piezoelectric substrate, or from mechanical waves in said piezoelectric substrate to radio frequency electromagnetic waves from said magnetoelastic and/or magnetostrictive resonators;
wherein said antenna apparatus performs reception in response to converting radio frequency electromagnetic radiation into radio frequency electrical signals, and performs transmission in response to converting radio frequency electrical signals into radio frequency electromagnetic radiation; and
wherein dynamic magnetic flux current oscillations in said plurality of magnetoelastic and/or magnetostrictive resonators are used as a fundamental source for detecting or radiating radio frequency electromagnetic waves.
