ABSTRACT:
A coaxial resonator with a distributed tuning capacity. The resonator includes one outer conductor and one central conductor, both conductors having a symmetry of revolution around a predetermined central axis. The tuning capacitor is fully distributed along the axis of the resonator and includes at least two cylindrical armatures nested into each other and having the axis of the resonator as their central axis, one of the two armatures constituting one of the two conductors of the resonator. The coaxial resonator may find particular application for RMN magnetometer probes.
