BROADBAND RECEIVING ANTENNA Russian patent published in 2023 - IPC H01Q7/00 

FIELD: radio technology.

SUBSTANCE: invention can be used to convert the magnetic field (MF) or the magnetic component of the electromagnetic field generated by harmonic or pulsed signal sources. A broadband receiving antenna contains a primary induction magnetometric transducer, an isolation capacitor and a resistive load connected in series, while the primary inductive magnetometric transducer and the resistive load are electrically connected to a common conductor at the first ends, connected to an isolation capacitor at the second ends. The capacitance C of the isolation capacitor is determined from the relation С=2L/(Rn+r)², where L and r are, respectively, the inductance and active resistance of the primary inductive magnetometric transducer at low frequency; Rn is the resistance of the resistive load.

EFFECT: reduction of the lower limiting frequency by a factor of ~ and increasing the steepness of the low-frequency slope of the frequency response of the device by a factor of two without changing the conversion coefficient.
