Abstract: An active magnetic antenna with a ferrite core having a winding is provided, forming a frame magnetic antenna which is connected with a low-noise transistor, to amplify a signal of the frame magnetic antenna. A base of the transistor is connected directly to one contact of the winding, and a second contact of the winding is capable of shifting a voltage of the base of the transistor. The impedance of the frame magnetic antenna is adjusted as a complex conjugate with an impedance of the base of the transistor of the low-noise amplifier, and the winding eliminates its own resonances.
