Abstract: The impedance of a loopstick antenna is directly modulated utilizing a mechanically actuated magnetoelastic material preferably placed in the core (or center) of looped wires forming the loopstick antenna. Using one or more mechanical actuators the permeability in the center of the loopstick antenna can be modulated at a rapid rate (such as with data or audio information), allowing the magnetic field outside of the antenna to be modulated at large bandwidths without requiring switches or modulators capable of high voltage thus reducing the overall complexity and cost of the transmitter. The external magnetic field is created by an AC source which is preferably impedance matched to the loopstick antenna by means of a matching network and is FM modulated according to a modulating signal applied to the one or more mechanical actuators.
