Abstract

Réseau d'antennes à microbandes ayant une polarisation linéaire à large bande et une polarisation circulaire à grande pureté de polarisation, des lignes de transmission (2) du réseau étant couplées capacitivement à des plaquettes de transmission (3) en un point de transmission unique ou en des points de transmission multiples, les plaquettes de transmission étant à leur tout couplées électromagnétiquement à des plaquettes rayonnantes correspondantes (4). Le couplage sans contact permet une fabrication à couches multiples simple et peu couteuse.
