International audienceThis paper presents a new three-dimensional frequency selective structure for single linear polarization filtering applications. Full-wave simulations of the structure in an infinite periodic configuration exhibit a wide band-pass response reaching 60%, with out-of-band rejection of at least 10 dB. Dielectric loading ensures miniaturization of the unit cell, which prevents the onset of Floquet harmonics in the bandwidth of interest, making the structure's response stable up-to 60° degrees of incidence angle. © 2020 EurAAP
