1. A magnetoelectric (ME) antenna, comprising:
one or more resonators electronically connected in series or in parallel, each of said resonators having a structure of
a magnetostrictive layer;
a top ground electrode layer;
a piezoelectric layer;
a bottom electrode layer; and
a substrate layer;
wherein said top ground electrode layer is deposited on said piezoelectric layer and is patterned with a shaped aperture; the magnetostrictive layer is also deposited on said piezoelectric layer through the shaped aperture; the piezoelectric layer is deposited on the bottom electrode layer which is deposited on the substrate layer;
thereby when in use the magnetostrictive layer and the piezoelectric layer form a heterostructure on the bottom electrode layer, leading to magnetization oscillation that radiates electromagnetic waves by an induced acoustic resonance frequency or converts the electromagnetic waves into a piezoelectric voltage output.
