Influence of a split double concentric ring resonator elements axial rotation on the microwave transmission line frequency-selective characteristics

摘要

The work is dedicated toward studying the methods for correcting the frequency characteristics of a passive transmission path of a strip-line or coplanar microwave transmission line, equipped by a split double concentric ring resonator on the transmission section reverse side of the printed circuit board (plate). This correction is carried out by rotation around the center of the concentric rings (or an axis passing through this point and perpendicular to the plane of the substrate) of both constituent elements of the resonator separately and of the whole resonant structure.
