A solidly mounted resonator (SMR)-based magnetoelectric (ME) antenna comprises a substrate, a Bragg reflector disposed on the substrate, a magnetostrictive/piezoelectric ME composite element disposed on the Bragg reflector, a first electrically conductive contact and a second electrically conductive contact. The first contact is disposed between the Bragg reflector and the magnetostrictive/piezoelectric ME composite element and electrically coupled to a bottom surface of the magnetostrictive/piezoelectric ME composite element. The second contact is disposed on top of the magnetostrictive/piezoelectric ME composite element and electrically coupled to the top of the magnetostrictive/piezoelectric ME composite element. The magnetostrictive/piezoelectric ME composite element comprises a magnetorestrictive multilayer deposited on a piezoelectric layer. The magnetorestrictive multilayer produces an in-plane uniaxial magnetic anisotropy (UMA). The UMA is a twofold UMA that exhibits a symmetric radiation pattern.
