BROADBAND SENSOR OF WEAK MAGNETIC FIELDS Russian patent published in 2024 - IPC G01R33/24 

FIELD: measurement.

SUBSTANCE: invention relates to measurement equipment and is intended for measurement of weak magnetic fields. Broadband sensor of weak magnetic fields contains a microwave generator, two microstrip resonators with thin magnetic films, two amplitude detectors, an adder, magnetic system, compensation measurement circuit, including repeater, high-pass filter, operational amplifier, feedback resistance, feedback coil, at that, the device contains two printed-circuit assemblies, on the first assembly there is a microwave generator, and on the second one, installed in the centre of the feedback coil, two microstrip resonators with thin magnetic films are arranged, wherein the axis of the feedback coil is orthogonal to the plane of the printed circuit assembly of the microwave generator.

EFFECT: wider operating frequency band of a broadband sensor of weak magnetic fields.
