Systematic design of a class of wideband circular polarizers using dispersion engineering

Abstract : A novel topology and a systematic procedure for the design of wideband linear-to-circular polarization converters are presented. The proposed configuration consists of three anisotropic inductive sheets, separated by two dielectric spacers. The dispersion curves for the two polarizations are engineered to achieve a broadband, linear phase response. The design procedure maximizes the differential phase bandwidth. The circuit parameters of the design are derived without any optimization. Fractional bandwidths larger than 48.5%, for incident angles up to 30°, are achieved. A printed circuit board (PCB) realization is discussed in order to numerically validate the proposed approach. © 2017 Euraap.
