Zusammenfassung:A magnetic transmitting antenna has a beam member having a first end and a second end, wherein the beam member comprising: an elastic member; at least one magnetoelastic member disposed on a first surface of the elastic member; and an actuator disposed on a second surface of the elastic member, wherein the actuator is configured to apply stress to the elastic member thereby applying a bending stress thereto for changing the magnetic permeability of the at least one magnetoelastic member, which in turn, changes an external magnetic field. At least one magnet is disposed adjacent to the magnetoelastic member such that magnetization is induced in the magnetoelastic member.
