<p>ANTENNA CIRCUIT An antenna circuit includes a ferrite core around which a main coil and a negative feedback coil are wound, and a field effect transistor (FET) with its source grounded, and with a voltage induced in the main coil being applied across the gate and the source of the FET to thereby form an aperiodic circuit and the drain of the FET being connected through the negative feedback coil to a load.</p> |
