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. %G English %L hal-01622469 %U https://univ-rennes.hal.science/hal-01622469 %~ UNIV-NANTES %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ IETR %~ STATS-UR1 %~ CENTRALESUPELEC %~ UR1-HAL %~ UR1-MATH-STIC %~ UR1-UFR-ISTIC %~ IETR-BEAMS %~ IETR-ADH %~ TEST-UNIV-RENNES %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ TEST-HALCNRS %~ UR1-MATH-NUM %~ IETR-SUMIT %~ NANTES-UNIVERSITE %~ UNIV-NANTES-AV2022
