Title of Invention

A TUNABLE AM RADIO ANTENNA IN THE FORM OF A FERRITE BAR LOOP ANTENNA

Abstract An AM radio antenna circuit having a ferrite bar loop antenna comprises a resonating structure forming a balacned antenna circuit, a varavtor diode tuning structure presenting a controllable capacitance to said winding structure, a DC path including the winding structure coupled to the varactor constructed and arranged to deliver a tuning signal to the varactor and means for connecting the actenna circuit to the input of an external detecotr integrated circuit.
