Abstract
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.
Highlights
Influence of a split double concentric ring resonator elements axial rotation on the microwave transmission line frequencyselective characteristics
When calculating the topological elements of this section of the transmission line, it was taken into account that in order to more efficiently absorb the power of the transmission line at a given frequency1,2 in the operating position, the sections with cut areas in the concentric rings of the double ring resonator will be perpendicular to the transmission line of electromagnetic power
The following possible rotary manipulations were simulated with the developed ring resonant structure (Fig. 1): (1) rotation of the inner ring of the split double concentric ring resonator (SDCRR), (2) rotation of the outer ring of the SDCRR, and (3) synchronous rotation of both SDCRR rings as a single design
Summary
When calculating the topological elements of this section of the transmission line, it was taken into account that in order to more efficiently absorb the power of the transmission line at a given frequency in the operating position, the sections with cut areas in the concentric rings of the double ring resonator will be perpendicular to the transmission line of electromagnetic power. The following possible rotary manipulations were simulated with the developed ring resonant structure (Fig. 1): (1) rotation of the inner ring of the split double concentric ring resonator (SDCRR), (2) rotation of the outer ring of the SDCRR, and (3) synchronous rotation of both SDCRR rings as a single design. In these cases, the rotation was carried out in a discrete manner by turning the corresponding ring (op rings) through a full turn (360○) with a step of 30○
