Classification: CPC G  H | IPC G  H

Claim 0:
1. A microwave resonator magnetic field measuring device (1) for measuring alternating magnetic fields, comprising:
a base plate (11) with at least one support/bearing/clamping point (111);
at least one mechanical oscillator (12+13) formed as an integrated microwave resonator in the form of a cantilever (13) having at least one magnetostrictive layer (12), the latter being connected and mounted at at least one point to the base plate (11) in the at least one supporting/bearing/clamping point (111),
at least one coupling means (161) for microwaves and
at least one decoupling means (162) for microwaves,
wherein the base plate (11) and the mechanical oscillator (12+13) are at least partly electrically conductive and electrically conductively connected to one another, and
wherein the microwave resonator magnetic field measuring device (1) is set up to detect, during operation, the mechanical deflection of the mechanical oscillator (12, 13) by the influence of an alternating magnetic field to be measured on the magnetostrictive layer (12) by means of the integrated microwave resonator.
