Abstract

Panneau de conversion de polarisation (PAN) comprenant une pluralité de cellules de conversion de polarisation (CEL) agencées en réseau compact régulier, chaque cellule du réseau comprenant un guide d’ondes métallique (GON) délimité par un port d’entrée (POE) et par un port de sortie (POS), le guide d’ondes métallique (GON) supportant un premier et un deuxième modes dégénérés à polarisations croisées et sensiblement linéaires, un tronçon du guide d’ondes (GON) de chaque cellule (CEL), appelé tronçon principal (TP), étant configuré pour que le premier et le deuxième modes dégénérés se propagent avec des vitesses de phase différentes. Figure pour l’abrégé : Fig. 8APolarization conversion panel (PAN) comprising a plurality of polarization conversion cells (CEL) arranged in a regular compact array, each cell of the array comprising a metallic waveguide (GON) bounded by an input port (POE) and via an output port (POS), the metallic waveguide (GON) supporting a first and a second degenerate mode with crossed and substantially linear polarizations, a section of the waveguide (GON) of each cell (CEL) , called main leg (TP), being configured so that the first and second degenerate modes propagate with different phase velocities.
