Latest Patents

One of his key patents is the "Reduced Q low frequency antenna." This invention describes a rod antenna and antenna circuit that utilize negative feedback to lower the Q factor of the antenna. The design incorporates a unique coil tapping arrangement that significantly reduces electric field susceptibility on the detected signal from the main coil. Additionally, different biasing arrangements are employed to minimize noise. In some embodiments, the main detector coil features a center tap that is AC grounded, with signal taps taken from the opposite ends of the main coil. These signals are then fed into a differential amplifier, whose output is connected to the magnetic circuit of the rod antenna through a second inductor winding that is magnetically coupled to the resonance circuit of the main antenna coil.
