Abstract

A possibility to design a compact polarization rotator based on the structures of dihedral symmetry is studied. Here, the diaphragms with several equal rectangular apertures are considered as dihedral symmetry structures. Ultimate performances of the rotators considered are obtained by using different optimization procedures. They demonstrate acceptable reflection in the predetermined frequency band. The rotators that achieve the polarization plane rotation by an angle of choice are examined as well.
