Several designs are presented covering either one or both sub-bands. Simulation results exhibit promising performance with gain levels in the range of 31-35.1 dBi for a 100-mm diameter aperture. The design of a switched focal array is presented and enables the coverage of an angular sector of ±6.6° with 5.1 dB gain variation in the lower band and ±6.9° with 6.8 dB gain variation in the upper band. © 2017 Euraap. %G English %L hal-01622485 %U https://hal-univ-rennes1.archives-ouvertes.fr/hal-01622485 %~ CEA %~ UNIV-NANTES %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ IETR %~ STATS-UR1 %~ CENTRALESUPELEC %~ DRT %~ UR1-HAL %~ UR1-MATH-STIC %~ UR1-UFR-ISTIC %~ IETR-BEAMS %~ IETR-ADH %~ TEST-UNIV-RENNES %~ LETI %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ CEA-GRE %~ TEST-HALCNRS %~ UR1-MATH-NUM %~ IETR-SUMIT %~ NANTES-UNIVERSITE %~ UNIV-NANTES-AV2022
