Title
(EN) RADIOFREQUENCY COMPONENT HAVING A PLURALITY OF WAVEGUIDE DEVICES PROVIDED WITH RIDGES
(FR) COMPOSANT RADIOFRÉQUENCE COMPORTANT PLUSIEURS DISPOSITIFS À GUIDE D'ONDE MUNI DE STRIES
Abstract
(EN)
A radiofrequency component (1) having a plurality of waveguide devices (2), for example antennas or polarizers, arranged in an array and designed to transmit and/or receive electromagnetic signals, the radiofrequency component (1) having a plurality of ridges (23), and each waveguide device having: at least one inner wall (3); an upstream aperture (24) located upstream with respect to the direction of propagation of the emitted signals; a downstream aperture (25) located downstream with respect to said direction of propagation of the emitted signals, which aperture is linked to the upstream aperture such that the emitted signals are transmitted from the upstream aperture to the downstream aperture; wherein the ridge arrangement in the downstream apertures (25) of each waveguide device (2) comprises no more and no fewer than three ridges (23).
