The accurate estimation of the direction of arrivals across the 3D half-space of incoming electromagnetic fields is obtained over a 1.7:1 frequency range from only two colocated and orthogonal circular arrays of Vivaldi antennas. %G English %2 https://enac.hal.science/hal-01977267/document %2 https://enac.hal.science/hal-01977267/file/aps_ursi_2018_Duplouy.pdf %L hal-01977267 %U https://enac.hal.science/hal-01977267 %~ UNIV-TLSE2 %~ UNIV-TLSE3 %~ ENAC %~ CNRS %~ INSA-TOULOUSE %~ LAAS %~ LAAS-MINC %~ TELECOM %~ TELECOM-EMA %~ UT1-CAPITOLE %~ LAAS-HYPERFREQUENCES-ET-OPTIQUE %~ INSA-GROUPE %~ TOULOUSE-INP %~ UNIV-UT3 %~ UT3-INP %~ UT3-TOULOUSEINP
