  • Electrically small self-resonant electro-quasistatic exciter and detector with canceled magnetic field
    Patent number: 12241923
    Abstract: An electrically small electroquasistatic antenna having a structure that reduces radiated magnetic fields and maintains suitable radiated electrical fields. The electroquasistatic antenna is a dipole antenna that is electrically short, which presents as a capacitor for use as an electroquasistatic antenna, with one or multiple counterposed inductive elements to resonate the antenna and provide high efficiency while simultaneously canceling the external magnetic fields. The electroquasistatic antenna may be configured for operation as an electroquasistatic exciter or electroquasistatic detector.
