Abstract
Compact, simple, ferromagnetic-filter coupling structures which provide a very high, effective-quality factor Q in the VHF, UHF, and microwave frequency ranges achieved by means of offsetting the ferromagnetic element from the plane of the coupling loops and by phase shifting the current in one of the coupling loops to produce an orthogonal field in the vicinity of the ferromagnetic element.
